Ingredients
- 4 boneless, skinless chicken breasts
- 2 cups marinara sauce
- 1 cup mozzarella cheese, shredded
- 1 cup mushrooms, sliced
- 1 teaspoon Italian seasoning
- Salt and pepper to taste
- Olive oil for greasing
How to Make It
Preheat your oven to 375°F (190°C). Allow the oven to fully preheat so the chicken begins cooking at the correct temperature.
Grease a baking dish with olive oil. Coat the bottom and sides lightly to help prevent sticking.
Season the chicken breasts with salt, pepper, and Italian seasoning, then place them in the baking dish. Season both sides of the chicken for balanced flavor throughout the dish.
Pour marinara sauce over the chicken, making sure it’s well coated. Spread the sauce evenly so it covers the chicken and helps keep it moist as it bakes.
Scatter the sliced mushrooms on top of the sauce. Distribute them evenly so every serving gets some savory mushroom flavor.
Sprinkle the mozzarella cheese over the entire dish. Cover the chicken and mushrooms with the shredded cheese for a golden, bubbly topping.
Bake in the oven for 25-30 minutes, or until the chicken reaches an internal temperature of 165°F (74°C) and the cheese is bubbly and golden. Check the chicken at the thickest part with an instant-read thermometer to confirm it is fully cooked.
Serve hot with pasta or a side salad. Spoon some of the marinara sauce over each serving for extra flavor.
How to Serve It
- Serve the chicken over pasta to soak up the marinara sauce.
- Pair it with a crisp side salad for a lighter, balanced meal.
- Add a simple vegetable side, such as roasted vegetables or steamed greens, to round out the plate.
How to Store It
Store leftovers in an airtight container in the refrigerator. Reheat individual portions gently in the microwave or place the chicken in a covered oven-safe dish and warm it until heated through. Avoid overheating, as this can make the chicken dry and the cheese chewy.
For longer storage, place cooled leftovers in a freezer-safe container and freeze. Thaw the chicken in the refrigerator before reheating for the best texture and most even results.
Helpful Tips
- Arrange the chicken breasts in a single layer so they cook evenly.
- Spread the marinara sauce over the chicken before adding the mushrooms and cheese to help keep the chicken moist.
- Always confirm doneness by checking that the chicken reaches an internal temperature of 165°F (74°C), especially if the breasts vary in thickness.
Optional Variations
- Add sliced bell peppers, spinach, or zucchini along with the mushrooms for extra vegetables.
- Replace some or all of the mozzarella with provolone or a blend of Italian cheeses.
- Add a pinch of red pepper flakes to the marinara sauce for a little heat.
Frequently Asked Questions
Can I use chicken thighs instead of chicken breasts?
Yes. Boneless, skinless chicken thighs can be used, but cooking time may vary. Check that the chicken reaches an internal temperature of 165°F (74°C).
Can I prepare this dish ahead of time?
You can assemble the chicken, marinara sauce, mushrooms, and cheese ahead of time and keep it refrigerated until ready to bake. Let the chilled dish sit briefly while the oven preheats, then bake until the chicken reaches 165°F (74°C).
How do I know when the mozzarella chicken bake is done?
The cheese should be bubbly and golden, and the chicken must reach an internal temperature of 165°F (74°C) at the thickest part.
What can I serve instead of pasta or salad?
Rice, roasted vegetables, steamed greens, or crusty bread all pair well with the marinara sauce and cheesy chicken.
