I couldn’t have guessed that stuffing chicken with roasted red peppers, sautéed spinach and oozy mozzarella would turn a simple weeknight into the kind of meal people beg me to bring to every party.

Jump to Recipe

I adore the rush when I slice into a chicken breast and molten mozzarella spills into bright strips of roasted red pepper. The contrast is ridiculous: juicy meat, pillowy cheese, tangy-sweet peppers cutting through every bite.

I love how it looks on the plate too, sunny slashes of red and soft white cheese pooling where the chicken gives way. And the pockets of filling keep every slice interesting instead of flat.

I crave this when guests are coming and when I’m too tired to fuss. Comfort without pretension.

Simple, bold, utterly addictive. I never tire of it.

No fuss required.

Big protein, keeps it hearty; you’ll get juicy slices.
Plus sweet, smoky pop; adds color and soft bite.
Basically bright green freshness; wilts down, makes it lighter.
Melty, gooey cheese pull; creamy, mild and comforting.
Garlicky punch that wakes it up without stealing the show.
It gives browning and flavor; makes edges crisp and tasty.
Salty, nutty boost; sprinkles extra savory depth.
Tiny heat pop; adds sparkle if you like a kick.
Herby backbone; it keeps things Mediterranean and a bit earthy.
Salt brings everything together; pepper adds little peppery bite.
Plus liquid that loosens pan bits, adds subtle tang.
Basically a light dusting for golden crust and better browning.
Holds it together so the cheese doesn’t escape during cooking.

Ingredient Quantities

4 boneless skinless chicken breasts (about 1 1/2 to 2 lbs total)

1 cup roasted red peppers, jarred and drained, sliced (about 1 large jar)

4 cups fresh spinach leaves (about 5 oz), roughly chopped

1 cup shredded mozzarella cheese (about 4 oz) or 4 oz fresh mozzarella, sliced

2 cloves garlic, minced

2 tablespoons olive oil, plus 1 tablespoon butter for cooking

1/4 cup grated Parmesan cheese (optional, but nice for flavor)

1/4 teaspoon red pepper flakes (optional)

1 teaspoon dried oregano or 1 tablespoon fresh chopped oregano

Salt and freshly ground black pepper, to taste (about 1 teaspoon salt total)

1/4 cup low sodium chicken broth or dry white wine for deglazing (optional)

2 tablespoons all purpose flour for light dredging (optional for browning)

Toothpicks or kitchen twine to secure the stuffed breasts

How to Make this

Print Recipe (No Advertisments)

1. Preheat oven to 375°F. Pat the 4 chicken breasts dry and, with a sharp knife, slice a pocket into the thick side of each breast without cutting all the way through; season inside and out with salt, pepper and the oregano.

2. In a skillet over medium heat, warm 2 tablespoons olive oil and 1 tablespoon butter. Add minced garlic and chopped spinach, sauté until wilted and most of the moisture is gone, about 2 to 3 minutes; season with a little salt and the red pepper flakes if using. Let cool slightly.

3. Chop or thinly slice the roasted red peppers. If using fresh mozzarella, thinly slice it; if shredded, measure 1 cup. In a bowl combine the spinach mixture, roasted red peppers, mozzarella and the grated Parmesan if using. Taste and adjust seasoning.

4. Stuff each chicken breast with an even amount of the filling, pressing it in gently. Secure openings with toothpicks or kitchen twine so filling wont fall out.

5. Optional light dredge: put 2 tablespoons flour on a plate, lightly toss each stuffed breast in flour shaking off excess. This gives a nicer browned crust but you can skip it if you like.

6. Heat a large ovenproof skillet over medium high heat with another tablespoon olive oil. Sear the stuffed breasts 2 to 3 minutes per side until golden brown. Be careful not to overcrowd the pan; do this in batches if needed.

7. If the pan has browned bits, deglaze with 1/4 cup low sodium chicken broth or dry white wine, scraping up those bits for extra flavor. Let the liquid reduce for a minute.

8. Transfer the skillet to the preheated oven and bake 18 to 22 minutes, or until an instant read thermometer in the thickest part of the breast reads 165°F and cheese is melted. If you used thin breasts, check earlier.

9. Remove from oven, let rest 5 minutes so juices redistribute. Remove toothpicks or twine, slice carefully or serve whole, spooning any pan juices over the chicken.

10. Garnish with a sprinkle of extra Parmesan or chopped fresh oregano if you like, and serve with your favorite sides.

FAQ

Can I make this ahead of time and bake later? Yes. You can assemble the stuffed breasts, secure them with toothpicks or twine, and refrigerate for up to 24 hours. Let them sit at room temp for 20 minutes before cooking so they cook evenly. If freezing, wrap tightly and freeze up to 2 months; thaw in the fridge overnight before baking.

How do I know the chicken is fully cooked without cutting it open? Use an instant read thermometer inserted into the thickest part of the breast (not touching cheese). It should read 165°F. If you dont have a thermometer, make a small test cut into one breast and check that juices run clear and there's no pink.

Can I use other cheeses or fillings? Absolutely. Provolone, fontina, or a sharp cheddar work well. You can swap roasted peppers for sun dried tomatoes, use kale instead of spinach, or add cooked mushrooms or cooked pancetta for extra flavor. Just dont overstuff or the chicken may not seal properly.

Do I need to dredge the chicken in flour? No, its optional. A light dredge helps create a golden sear when pan browning but you can skip it for a lighter dish or to keep it gluten free. If you skip flour, just increase the pan heat a little and add more oil to get good color before finishing in the oven.

What’s the best way to prevent the filling from leaking out? Pat chicken dry, make a neat pocket with a sharp knife, dont overfill, and use toothpicks or kitchen twine to close the openings. Browning seam-side down first helps seal them. Let them rest 5 minutes after baking so melted cheese settles instead of oozing out.

How should I store and reheat leftovers? Refrigerate leftovers in an airtight container for up to 3 days. Reheat gently in a 325°F oven for 10 to 15 minutes until heated through, or microwave in short bursts to avoid rubbery chicken and over-melted cheese. If frozen, thaw overnight before reheating.

Savory Stuffed Chicken With Roasted Red Peppers, Spinach, And Mozzarella Recipe Substitutions and Variations

Chicken breasts: swap with boneless skinless turkey cutlets or pork tenderloin medallions, or use large bone-in chicken thighs but cook a bit longer so they’re done through.
Roasted red peppers: use sun dried tomatoes (rehydrated) for a chewier tang, or jarred marinated artichoke hearts for a different savory note, or roasted poblano for a smoky kick.
Fresh spinach: substitute baby kale or Swiss chard (tough stems removed) or frozen chopped spinach that’s been thawed and squeezed dry, just cook it a little longer.
Mozzarella cheese: swap with provolone, fontina, or even a mild cheddar for melty goodness, or use crumbled feta for a saltier, tangy result.

Pro Tips

1. Pound the thicker parts of breasts a little so they’re even. They’ll cook more evenly and you won’t get one overdone and one underdone. Don’t go crazy though, just a few light taps.

2. Squeeze excess moisture from the wilted spinach before mixing it with the cheese. Too much water = soggy filling and watery pan juices, and nobody likes that.

3. Brown in a hot pan, but don’t rush the oven time. A good sear gives flavor, but if you skip the final oven rest you’ll squeeze out all the juices when cutting. Let it sit 4 to 6 minutes after baking.

4. If you’re worried about filling leaking, tuck in with toothpicks and set the seam side down when searing and baking; it helps seal things. Also, use a thermometer — it’s the easiest way to avoid dry chicken.
