What Is Stuffed Chicken Breast?
Stuffed chicken breast is a boneless chicken breast sliced open and filled with cheese, vegetables, herbs, or other flavorful ingredients before cooking. In this recipe, the chicken is filled with mozzarella, spinach, and sun-dried tomatoes, then seared and baked until juicy.
Ingredients for Sun Dried Tomato Stuffed Chicken Breast
For the Stuffed Chicken
- 2 small boneless, skinless chicken breasts, about 6 ounces each (180 g each)
- 1/2 cup oil-packed sun-dried tomatoes, drained and sliced (70 g)
- 4 slices mozzarella cheese (85 g)
- 1 packed handful fresh spinach leaves (30 g)
- 2 teaspoons olive oil (10 ml)
the Italian Dressing
- 1 tablespoon Dijon mustard (15 g)
- 1 tablespoon white wine vinegar or lemon juice (15 ml)
- 1/2 teaspoon granulated sugar (2 g)
- 2 teaspoons olive oil (10 ml)
- 1/2 teaspoon Italian seasoning
- 1/2 teaspoon red pepper flakes
- 1/4 teaspoon salt, or to taste
- 1/4 teaspoon black pepper, or to taste

Ingredient Notes and Substitutions
Use small chicken breasts so they cook quickly and stay juicy. If your chicken breasts are larger, bake them for a few extra minutes and check the internal temperature.
Oil-packed sun-dried tomatoes add the best flavor and moisture. Drain them well and pat them dry before stuffing the chicken so excess oil does not make the filling slippery. Unlike dry-packed sun-dried tomatoes, oil-packed tomatoes do not need soaking before use. See Bon Appétit’s guide to oil-packed sun-dried tomatoes for more helpful tips.
Mozzarella gives the filling a stretchy, melty texture. Provolone, Monterey Jack, fontina, or cheddar also work well. For the best melt, use cheese from a block and slice or shred it yourself when possible. See King Arthur Baking’s guide to the best melting cheeses for more options.
Fresh spinach wilts quickly inside the chicken. Frozen spinach can be used after thawing and squeezing out all excess water. For a fresh side that matches the garlic, basil, and tomato flavors in this recipe, serve it with this Tomato Basil Salad with Garlic and Shallots.
Use lemon juice instead of white wine vinegar for a slightly fresher flavor.
How to Make Stuffed Chicken Breast
- Preheat the oven to 350°F (180°C). Lightly oil a baking sheet or oven-safe skillet.
- In a small bowl, whisk together the Dijon mustard, white wine vinegar, sugar, olive oil, Italian seasoning, red pepper flakes, salt, and black pepper.
- Place the chicken breasts on a cutting board. Slice each chicken breast horizontally through the middle, stopping before cutting all the way through, then open it like a book.
- Coat the inside and outside of the chicken with the Italian dressing.

- Add sun-dried tomatoes to one side of each chicken breast. Layer with two slices of mozzarella and a small handful of spinach.
- Fold the chicken closed over the filling. Secure with toothpicks if needed.
- Heat 2 teaspoons olive oil in a skillet over medium-high heat. Sear the chicken for about 1 1/2 minutes per side until lightly golden.
- Transfer the chicken to the prepared baking sheet or leave it in an oven-safe skillet. Bake for 15 minutes, until the cheese is melted and the chicken reaches 165°F (74°C) in the thickest part.

- Rest the chicken for 3 minutes before slicing. Spoon any pan juices over the top before serving.For an easy complete dinner, serve the stuffed chicken with Garlic Butter Rice and a simple green vegetable or salad.

Expert Tips for Juicy Stuffed Chicken Breast
- Pat the chicken dry before adding the dressing so the seasoning sticks well.
- Do not cut completely through the chicken when making the pocket.
- Keep the filling away from the edges to prevent cheese from leaking out.
- Use toothpicks only when needed, then remove them before serving.
- Sear the chicken just until golden because it will finish cooking in the oven.
- Check the internal temperature with a meat thermometer instead of relying only on cooking time. Insert it into the thickest part of the chicken, avoiding the filling, and cook until it reaches 165°F (74°C). See FoodSafety.gov’s safe minimum internal temperature chart for more guidance.
- Let the chicken rest before slicing so the juices stay inside.
- Slice the chicken carefully with a sharp knife to show the spinach, cheese, and sun-dried tomato filling.
Storage and Freezing
- Store leftover stuffed chicken in an airtight container in the refrigerator for up to 3 days.
- Reheat gently in a 325°F oven or microwave until warmed through. Add a small splash of water or chicken broth before reheating to keep the chicken moist.
- To freeze, let the cooked chicken cool completely, wrap each breast tightly, and freeze for up to 2 months. Thaw overnight in the refrigerator before reheating.
Variations
Cream Cheese Stuffed Chicken
- Replace mozzarella with softened cream cheese for a creamy filling.
Feta and Spinach Chicken
- Use crumbled feta instead of mozzarella for a tangier Mediterranean-style version.
Pesto Stuffed Chicken
- Spread 1 tablespoon basil pesto inside each chicken breast before adding spinach and cheese.
Mushroom Stuffed Chicken
- Add sautéed mushrooms with the spinach and mozzarella.
Bacon and Cheese Stuffed Chicken
- Add cooked chopped bacon for a smoky, savory filling.
