Cheesy baked chicken breast and peppers is a colorful one-dish dinner: chicken breasts and sliced red, yellow and green bell peppers tossed with olive oil, garlic, paprika and oregano, spread in a casserole dish, covered with cheddar and Parmesan and baked until the chicken is juicy and the cheese is golden. It takes 40 minutes and serves 4.
How to make it: Toss the chicken with the garlic, spices, salt, pepper and olive oil, then add the sliced peppers and toss again. Arrange everything in a 9×13 dish, sprinkle with both cheeses and bake at 375°F for 25 to 30 minutes, until the chicken reaches 165°F. Finish with parsley.

Why You’ll Love It

- Cheesy crust: cheddar and Parmesan melt into a golden top.
Can You Cook Raw Chicken and Peppers at the Same Time?
Yes. Thinly sliced peppers roast in about the same time it takes chicken breasts to cook through at 375°F. They soften, sweeten and release a little juice that keeps the chicken moist. Spread them around and under the chicken in an even layer so everything cooks at the same rate. Just make sure the chicken reaches 165°F in the thickest part before serving.
Ingredient Notes
Chicken breasts: 4 boneless, skinless breasts. Pound thick ends to an even thickness so they cook evenly.
Bell peppers: 1 each red, yellow and green, thinly sliced.
Seasoning: 2 cloves of garlic, 1 teaspoon each of paprika and dried oregano, salt and pepper, and 3 tablespoons olive oil.
Cheese: 1 cup shredded cheddar and 1/2 cup grated Parmesan.
Parsley: fresh, chopped, to finish.

Is It Better to Bake Chicken Breast at 350 or 400?
Somewhere in between works best for this dish. This recipe uses 375°F: hot enough to roast the peppers and melt the cheese to golden, but gentle enough that the chicken stays juicy while it cooks through. Higher heat cooks faster but can dry out the edges before the center is done; lower heat takes longer and won’t brown the cheese as well.
The Secret to Flavorful Cheesy Chicken
- Season the chicken well. Paprika, garlic and oregano coat every piece before the cheese goes on.
- Even thickness. Pound thick breasts so they cook evenly and stay juicy.
- Two cheeses. Cheddar melts creamy; Parmesan adds salty, nutty flavor and browns.
- Don’t overbake. Pull it at 165°F and let it rest a few minutes.
- Spoon the juices over. The peppers and chicken make a flavorful pan sauce.
How to Keep the Chicken Juicy
Chicken breasts dry out when the thin end overcooks while the thick end catches up. Pound them to an even thickness between two sheets of plastic wrap, or slice very thick breasts in half horizontally. Coating them in olive oil before seasoning helps hold in moisture, and the cheese on top acts like a lid. Check early with a thermometer and take the dish out as soon as the thickest piece reaches 165°F.
Variations
- Fajita style: use fajita seasoning and pepper jack, and add sliced onion.
- Italian: swap the cheddar for mozzarella and add Italian seasoning.
- More vegetables: add zucchini, mushrooms or red onion.
- Chicken thighs: boneless thighs stay extra juicy; bake to 165°F.
- Sliced chicken: cut the breasts into strips for a faster bake.
Storage & Reheating
Refrigerate leftovers within 2 hours and eat them within 3 to 4 days. Reheat covered in the oven or microwave until hot, to 165°F. Leftovers are great sliced into wraps or over rice.
What to Serve With It
Serve it with rice, quinoa, roasted potatoes, pasta or a green salad.
