Step-by-Step Instructions
This casserole is straightforward but packed with flavor. Follow these detailed steps to get it right, even if you’re new to cooking.
1. Preheat the Oven
Set your oven to 375°F (190°C). This gives it time to reach the right temperature while you prep everything else.
If your oven runs hot or cool, adjust slightly and keep an eye on the cooking time later.
2. Season and Sear the Chicken
Pat the chicken breasts dry with a paper towel to ensure a nice sear. Sprinkle both sides with salt, black pepper, and Italian seasoning.
Heat olive oil in a large skillet over medium-high heat.
Once the oil shimmers, add the chicken and sear for 3-4 minutes per side until golden brown.
You’re not cooking them through—just getting a nice crust. Transfer the chicken to a plate and set aside.
3. Prepare the Sauce
In the same skillet, reduce the heat to medium and add the minced garlic.
Stir for about 30 seconds until fragrant, being careful not to burn it. Add the sun-dried tomatoes, heavy cream, and chicken broth.
Stir well to combine, scraping up any browned bits from the skillet for extra flavor. Let the sauce simmer for 2-3 minutes until it starts to thicken slightly.
Stir in the Parmesan cheese and red pepper flakes (if using) until the cheese melts into the sauce.
4. Assemble the Casserole
Place the seared chicken breasts in a 9×13-inch baking dish. Pour the creamy sauce evenly over the chicken, making sure each piece is well-coated.
Sprinkle the mozzarella cheese over the top, covering the chicken and sauce.
5. Bake the Casserole
Place the baking dish in the preheated oven and bake for 20-25 minutes, or until the chicken reaches an internal temperature of 165°F (74°C) and the cheese is bubbly and golden.
If you want a more golden top, you can broil for 1-2 minutes at the end, but watch closely to avoid burning.
6. Garnish and Serve
Remove the casserole from the oven using oven mitts. Sprinkle fresh basil over the top for a pop of color and flavor.
Let it rest for 5 minutes before serving to let the sauce settle.

Tips for Success
Getting this casserole just right is easy with a few pointers. I’ve learned these from making it a bunch of times, and they’ll help you avoid any hiccups.
- Use a meat thermometer to ensure the chicken is cooked to 165°F (74°C).
- Drain the sun-dried tomatoes well to avoid an oily sauce.
- Don’t skip the sear—it locks in the chicken’s juices.
- If the sauce is too thick, add a splash more chicken broth.
- Taste the sauce before baking and adjust seasoning as needed.

Serving Suggestions
This casserole is a star on its own, but pairing it with the right sides takes it to the next level. It’s rich and creamy, so I like to balance it with something light or starchy to soak up that delicious sauce.
- Serve with pasta like fettuccine or penne to mop up the sauce.
- Pair with a crisp green salad with a tangy vinaigrette.
- Roast some asparagus or broccoli for a veggie side.
- Offer crusty bread to scoop up every last bit of sauce.
- Try it with mashed potatoes for ultimate comfort.
