2. It is packed with flavor

Sun-dried tomatoes bring concentrated tomato flavor and a slightly tangy, savory taste. Garlic, Italian seasoning, Parmesan, mozzarella, and herbs add even more depth.

3. Sweet corn balances the savory ingredients

Corn is an easy ingredient that can completely transform a casserole. Its natural sweetness balances the salty cheese and tangy sun-dried tomatoes.

You do not need a long list of unusual ingredients. Most of the ingredients are easy to find at a typical American grocery store.

Ingredients for Sun-Dried Tomato Chicken Casserole

For approximately 4 servings, you will need:

1 ½ pounds boneless, skinless chicken breasts
1 tablespoon olive oil
3 cloves garlic, minced
½ cup sun-dried tomatoes, chopped
1 ½ cups corn kernels, fresh, frozen, or canned and drained
1 cup heavy cream
½ cup chicken broth
½ cup freshly grated Parmesan cheese
1 cup shredded mozzarella cheese
1 teaspoon Italian seasoning
½ teaspoon smoked paprika
½ teaspoon onion powder
½ teaspoon salt, or to taste
¼ teaspoon black pepper
¼ teaspoon red pepper flakes, optional
1 tablespoon fresh parsley, chopped
1 tablespoon fresh basil, chopped, optional
1 tablespoon butter
1 teaspoon lemon juice, optional

Choosing the Best Chicken

Boneless, skinless chicken breasts work especially well because they cook quickly and are easy to cut into bite-sized pieces.

You can also use boneless chicken thighs if you prefer darker meat. Chicken thighs generally have a richer flavor and can stay juicy during cooking.

For an even faster dinner, cooked rotisserie chicken can be substituted. Simply shred or chop the cooked chicken and add it when the creamy sauce is prepared.

If using raw chicken, always cook it to a safe minimum internal temperature of 165°F as measured with a food thermometer. USDA guidance also recommends checking the thickest part of poultry rather than relying only on color.

What Makes Sun-Dried Tomatoes So Good in Chicken Casserole?

Sun-dried tomatoes are one of the easiest ways to add intense tomato flavor to a quick dinner.

Fresh tomatoes contain a lot of water, while sun-dried tomatoes have a concentrated flavor. They bring savory tomato notes, mild sweetness, tanginess, and a pleasant chewy texture.

When combined with creamy ingredients, sun-dried tomatoes create a flavor profile similar to popular creamy Tuscan-style chicken dishes, but the addition of corn gives this casserole its own unique character.

If your sun-dried tomatoes are packed in oil, you can drain them and reserve a little of the flavorful oil for cooking the chicken.

How to Make Sun-Dried Tomato Chicken Casserole in 30 Minutes

Step 1: Prepare the Chicken

Cut the chicken breasts into small, evenly sized bite-sized pieces.

Season them with salt, black pepper, smoked paprika, onion powder, and Italian seasoning.

Cutting the chicken into similarly sized pieces helps it cook more evenly and quickly.

Step 2: Sear the Chicken

Heat olive oil and butter in a large oven-safe skillet over medium-high heat.

Add the seasoned chicken pieces in a single layer.

Cook for approximately 4 to 6 minutes, turning occasionally, until the chicken is lightly golden and nearly cooked through.

Do not overcrowd the pan. If necessary, cook the chicken in batches.

Remove the chicken from the skillet and place it on a clean plate.

Step 3: Cook the Garlic and Sun-Dried Tomatoes

Reduce the heat to medium.

Add the minced garlic and chopped sun-dried tomatoes to the same skillet.

Cook for approximately 30 to 60 seconds.

The garlic should become fragrant without turning dark brown.

If your sun-dried tomatoes were packed in oil, a small spoonful of their oil can add even more flavor.

Step 4: Add the Corn

Add the corn kernels to the skillet.

Cook for 1 to 2 minutes, stirring occasionally.

Fresh corn, frozen corn, or canned corn can all work.

If using canned corn, drain it well before adding it to the skillet.

Step 5: Create the Creamy Sauce

Pour in the chicken broth and heavy cream.

Stir everything together while scraping the bottom of the skillet with a wooden spoon.

Those browned bits from the chicken add excellent flavor to the sauce.

Add the Parmesan cheese and stir until the sauce becomes smooth and creamy.

Taste and adjust the seasoning.

For a little heat, add red pepper flakes.

Step 6: Return the Chicken

Place the cooked chicken back into the skillet.

Stir gently so the chicken is coated in the creamy sun-dried tomato sauce.

Allow everything to simmer for a few minutes until the chicken is fully cooked and the sauce has thickened slightly.

Step 7: Add the Cheese

Sprinkle shredded mozzarella evenly over the top.

If using an oven-safe skillet, place the skillet under the broiler for 1 to 3 minutes until the cheese is melted and lightly golden.

Watch carefully because cheese can brown quickly under a broiler.

Alternatively, cover the skillet with a lid for several minutes until the mozzarella melts.

The finished casserole should be creamy, bubbling, and loaded with melted cheese.

Step 8: Garnish and Serve

Remove the skillet from the heat.

Finish with fresh parsley and basil.

A small squeeze of lemon juice can brighten the creamy sauce and balance the richness.

Serve immediately while the cheese is warm and gooey.

The Secret to a Creamy Chicken Casserole

The key to a creamy casserole is controlling the heat.

Heavy cream can create a rich sauce, but cooking it too aggressively can cause the sauce to reduce too quickly.

Keep the sauce at a gentle simmer rather than a violent boil.

Parmesan also helps thicken the sauce while adding salty, nutty flavor.

For an even thicker casserole, you can add a small amount of cream cheese. About 2 to 3 tablespoons is usually enough to create an extra-creamy texture.

Can You Use Frozen Corn?

Absolutely.

Frozen corn is one of the easiest ingredients to keep on hand for quick dinners.

You do not necessarily need to thaw frozen corn first. Add it directly to the skillet and cook until heated through.

Frozen corn can also retain a nice texture and sweetness.

Can You Use Canned Corn?

Yes.

Canned corn is convenient and works beautifully in this recipe.

Make sure you drain it well before adding it to the skillet.

If the corn contains a lot of excess liquid, it can make the creamy sauce thinner than intended.

Fresh Corn Variation

If fresh corn is in season, remove the kernels from approximately 2 to 3 ears of corn.

Fresh corn brings a crisp texture and natural sweetness that pairs wonderfully with sun-dried tomatoes.

For summer dinners, fresh corn makes this casserole particularly delicious.

How to Make This Recipe Spicy

If you enjoy spicy chicken recipes, there are several easy ways to increase the heat.

Add:

Red pepper flakes
Cayenne pepper
Chopped jalapeño
Hot Italian sausage
Crushed red pepper
A drizzle of hot sauce
Pepper Jack cheese instead of mozzarella

For mild heat, start with ¼ teaspoon red pepper flakes.

For a more intense spicy chicken casserole, increase gradually according to your preference.

How to Add Vegetables

This casserole is incredibly flexible.

You can add vegetables such as:

Spinach

Stir in 2 to 3 cups of fresh spinach toward the end of cooking. The spinach will quickly wilt into the creamy sauce.

Mushrooms

Sauté sliced mushrooms after cooking the chicken and before making the sauce.

Bell Peppers

Red, yellow, or orange bell peppers add sweetness and color.

Broccoli

Use small broccoli florets and cook them until tender before combining them with the casserole.

Zucchini

Diced zucchini cooks quickly and works well with the creamy tomato sauce.

Asparagus

Fresh asparagus makes an excellent spring variation.

Make It a Chicken Pasta Casserole

Want to make the meal even heartier?

Add cooked pasta.

Penne, rotini, bow-tie pasta, rigatoni, or shells all work well.

Cook approximately 8 ounces of pasta according to the package directions.

Drain it and stir it into the creamy chicken mixture.

Add a little extra chicken broth or cream if necessary to loosen the sauce.

Top with mozzarella and bake or broil until bubbling.

This creates a delicious sun-dried tomato chicken pasta casserole that is perfect for family dinners.

Make It a Chicken and Rice Casserole

For a comforting rice-based version, serve the creamy chicken and corn mixture over cooked white rice, brown rice, jasmine rice, or basmati rice.

You can also stir cooked rice directly into the sauce.

Rice absorbs the creamy sun-dried tomato sauce beautifully.

For meal prep, divide the chicken, corn, and rice into individual containers.

Best Cheese Choices

Mozzarella is a great choice because it melts smoothly and creates a stretchy cheese topping.

Parmesan provides a stronger savory flavor.

You can also experiment with:

Provolone
Monterey Jack
Colby Jack
Fontina
Cheddar
Pepper Jack
Asiago

A combination of mozzarella and Parmesan provides an excellent balance between meltability and flavor.

What to Serve with Sun-Dried Tomato Chicken Casserole

Although this casserole can easily be served as a complete meal, adding a simple side dish makes dinner feel even more special.

Garlic Bread

Warm garlic bread is perfect for soaking up the creamy sauce.

Green Salad

A crisp salad with lettuce, cucumber, tomatoes, and a light vinaigrette provides freshness alongside the rich casserole.

Roasted Vegetables

Roasted broccoli, asparagus, zucchini, or green beans make excellent side dishes.

Steamed Green Beans

Green beans provide a fresh contrast to the creamy chicken.

Rice

Serve the casserole over rice if you want an extra hearty meal.

Pasta

Pasta turns the dish into a complete creamy chicken pasta dinner.

How to Store Leftover Chicken Casserole

Allow leftovers to cool promptly and place them in shallow, covered containers.

USDA guidance recommends refrigerating perishable cooked food promptly and using most cooked leftovers within 3 to 4 days.

Store the casserole in the refrigerator and reheat individual portions as needed.

For food safety, leftovers should be reheated to 165°F.

Can You Freeze This Casserole?

Yes, although the creamy sauce may change slightly in texture after freezing and thawing.

For best results, cool the casserole completely before transferring it to a freezer-safe airtight container.

Freeze for up to approximately 2 to 3 months for best quality.

Thaw overnight in the refrigerator.

Reheat gently and stir occasionally.

If the sauce becomes too thick, add a splash of chicken broth or cream.

Meal Prep Tips

This recipe can work well as part of a weekly meal-prep routine.

Prepare the chicken and sauce, then divide the casserole into individual containers.

Pair each portion with:

Rice
Pasta
Roasted vegetables
Salad
Quinoa
Potatoes

Allow food to cool appropriately before refrigeration.

For the best texture, store fresh garnishes separately and add them just before serving.

How to Make the Recipe Lighter

If you want a lighter version, there are several substitutions you can make.

Replace some of the heavy cream with half-and-half.

Use reduced-fat mozzarella.

Increase the amount of vegetables.

Serve the chicken mixture with a large green salad rather than pasta or rice.

You can also use chicken breast instead of chicken thighs.

Keep in mind that changing the ingredients may change the final texture and richness of the sauce.

How to Make It Extra Creamy

For an ultra-creamy chicken casserole, add:

2 ounces cream cheese
Extra Parmesan
A splash of heavy cream
1 tablespoon butter

Cream cheese is particularly useful because it thickens the sauce and gives it a rich, silky texture.

Allow it to soften before adding it to the skillet so it incorporates smoothly.

Tips for Perfect Chicken Every Time

Cut the chicken evenly

Uneven pieces cook at different speeds.

Don’t overcrowd the pan

Crowding causes chicken to steam instead of brown.

Use medium-high heat

This helps create a flavorful golden exterior.

Don’t overcook the chicken

Chicken breasts can become dry when overcooked.

Use a thermometer

USDA recommends cooking poultry to 165°F measured with a food thermometer.

Let the sauce simmer gently

A gentle simmer helps create a smooth creamy texture.

Common Mistakes to Avoid

Adding Too Much Liquid

Too much broth can make the casserole watery.

Start with the recommended amount and add more only if needed.

Burning the Garlic

Garlic cooks quickly.

Once it becomes fragrant, move on to the next ingredient.

Burned garlic can taste bitter.

Using Too Much Salt

Sun-dried tomatoes, Parmesan, chicken broth, and cheese can all contain salt.

Taste the sauce before adding additional salt.

Overcooking the Chicken

Cook until the chicken reaches the safe temperature, then avoid unnecessary additional cooking.

Skipping the Browning Step

Searing the chicken creates flavorful browned bits that make the final sauce more delicious.

Flavor Variations

Tuscan-Style Chicken Casserole

Add spinach and mushrooms for a Tuscan-inspired variation.

Spicy Sun-Dried Tomato Chicken

Add red pepper flakes and Pepper Jack cheese.

Creamy Garlic Chicken

Increase the garlic and add extra Parmesan.

Mediterranean Chicken Casserole

Add olives, feta cheese, oregano, spinach, and roasted red peppers.

Southwest Chicken Casserole

Replace Italian seasoning with chili powder and cumin. Add black beans, corn, jalapeño, and Monterey Jack cheese.

Bacon Chicken Casserole

Add cooked, crumbled bacon for smoky flavor.

Lemon Herb Chicken Casserole

Add fresh lemon zest, lemon juice, parsley, and oregano.

Frequently Asked Questions

Can I make this casserole without heavy cream?

Yes. Half-and-half can be used, although the sauce will be somewhat lighter.

You can also use evaporated milk for a creamy alternative.

Can I use chicken thighs?

Absolutely.

Boneless, skinless chicken thighs are flavorful and work very well in creamy chicken recipes.

Can I use rotisserie chicken?

Yes.

Rotisserie chicken makes this recipe even faster. Simply shred or chop approximately 3 to 4 cups of cooked chicken and add it to the sauce.

Can I make this without cheese?

Yes, although cheese contributes richness and helps create the classic casserole texture.

You can leave it out or use a dairy-free cheese alternative.

Can I make it gluten-free?

The basic ingredients can be used for a gluten-free version, but always check individual ingredient labels, especially broth, seasoning blends, and packaged products.

Can I make it dairy-free?

Use dairy-free cream or coconut cream and dairy-free cheese alternatives.

The flavor will change somewhat, but the recipe can still be delicious.

What kind of sun-dried tomatoes should I use?

Oil-packed sun-dried tomatoes are particularly flavorful and convenient.

Drain them before chopping.

Dry-packed tomatoes can also work, but they may need to be softened according to package directions.

Can I use frozen chicken?

For this quick recipe, thawed chicken is easiest because it can be cut into small pieces and cooked quickly.

USDA recommends safe thawing in the refrigerator, cold water, or microwave rather than on the counter.

How do I know when the casserole is done?

Use a food thermometer.

The chicken and casserole should reach 165°F. USDA specifically lists casseroles at 165°F as a safe minimum internal temperature.
