How to Make Creamy Marry Me Chicken Casserole
Step 1: Prep the Chicken
- Preheat your oven to 375°F (190°C). Grease a 9×13-inch casserole dish.
- Season diced chicken with salt, pepper, and Italian seasoning.
- In a large skillet, heat olive oil over medium-high heat. Add the chicken and cook until lightly golden on the outside and just cooked through, about 5-6 minutes. Remove from heat and set aside.

Step 2: Make the Creamy Sauce
- In the same skillet, add garlic and sun-dried tomatoes. Sauté for 1-2 minutes until fragrant.
- Stir in crushed red pepper flakes (if using), heavy cream, chicken broth, and Parmesan cheese. Whisk until cheese is melted and the sauce is smooth.
- Stir in sour cream and 1 cup mozzarella cheese, letting it melt into the sauce. Simmer on low for 2-3 minutes to thicken.
Step 3: Assemble the Casserole
- In a large mixing bowl, combine cooked pasta, cooked chicken, creamy sauce, and chopped fresh basil. Toss gently until evenly coated.
- Spread mixture into the prepared casserole dish. Top with remaining 1/2 cup mozzarella cheese.
Step 4: Bake to Perfection
- Bake uncovered for 20-25 minutes until bubbly and golden on top.
- Let cool for 5 minutes. Garnish with extra basil and serve hot!
