This spinach stuffed chicken breast is the kind of dinner that looks like you spent hours in the kitchen but takes about 35 minutes start to finish. Juicy chicken breasts stuffed with a creamy, garlicky Boursin filling loaded with fresh spinach, melty mozzarella, and Parmesan — seared golden in a skillet and finished in the oven until perfectly cooked through.
Why You’ll Love This Recipe
- That Boursin filling. Creamy, garlicky, herby, and melted together with mozzarella and Parmesan — it’s rich, satisfying, and completely irresistible. One package of Boursin transforms a basic stuffed chicken into something restaurant-worthy.
- Sear then bake method. Searing the chicken first gives you a beautifully golden crust. Finishing in the oven ensures the inside cooks through evenly without drying out. It’s the technique that makes all the difference.
- One skillet. Sear and bake in the same pan. No extra dishes, no transferring to a baking dish — straight from stovetop to oven.
- Impressive enough for guests. This is the recipe we pull out when we have people over and want to look like we really know what we’re doing. It never fails to impress.
- Ready in 35 minutes. Prep is 10 minutes. The rest is mostly hands-off oven time.
You’ll Need
How to Make Spinach Stuffed Chicken Breast
Full recipe card with exact quantities is below.
- Mix Boursin, spinach, mozzarella, and Parmesan until creamy.
- Cut a deep pocket into each chicken breast (don’t cut through). Stuff evenly and secure with toothpicks if needed.
- Season all over with salt, pepper, garlic powder, and paprika.
- Heat olive oil in an oven-safe skillet over medium heat. Sear chicken 3–4 minutes per side until golden.
- Transfer to oven and bake 10–15 minutes, until internal temperature reaches 165°F.
Helpful Tips
- Cut the pocket carefully. Use a sharp knife and take your time. Insert the tip into the thickest part of the breast and work the blade back and forth to make a deep, even pocket. The deeper the pocket, the more filling you can fit — and the better every bite tastes.
- Don’t overstuff. It’s tempting to pack in as much filling as possible, but overstuffed chicken bursts open during cooking. Fill it generously but leave a little room at the opening.
- Use toothpicks. For larger pockets or chicken that keeps wanting to open, a toothpick or two across the opening keeps everything sealed while it cooks. Just remember to remove them before serving.
- Don’t skip the sear. The golden crust from searing adds flavor and texture that you simply can’t get from baking alone. It also seals the outside so the filling stays inside during the oven phase.
Substitutions & Variations
- Boursin flavor: Garlic & Fine Herbs is our go-to but Shallot & Chive Boursin is equally delicious. Both work perfectly in this filling.
- Spinach: Fresh baby spinach is ideal. Frozen spinach works too — thaw it completely and squeeze out every drop of water before mixing into the filling, otherwise the filling will be watery.
- Mozzarella: Provolone or Gruyère are great substitutes for a slightly different flavor profile.
- Add sun-dried tomatoes: A small handful of chopped sun-dried tomatoes mixed into the filling adds a sweet, tangy depth that works beautifully with the Boursin.
- Add red pepper flakes: A pinch mixed into the filling or the seasoning blend adds a gentle heat that contrasts nicely with the rich, creamy filling.
- Wrap in bacon: Wrap each stuffed chicken breast in 2–3 slices of bacon before searing. It adds incredible flavor and keeps the filling sealed inside naturally.
What to Serve with Spinach Stuffed Chicken Breast
The pan juices from this chicken are liquid gold — make sure whatever you serve it with can soak them up.
- Garlic mashed potatoes — the classic pairing and our personal favorite
- Roasted asparagus or broccolini — the slight char complements the creamy filling perfectly
- Steamed rice or orzo — simple sides that let the chicken shine
- Crusty bread — for mopping up every last drop of those pan juices
- Simple green salad — a light, fresh contrast to the rich filling
Storage & Reheating
- Fridge: Store leftovers in an airtight container for up to 3 days.
- Reheating: Warm in a skillet over low heat with a small splash of chicken broth or water to keep the chicken moist. You can also reheat in the oven at 325°F for about 10 minutes covered with foil. Avoid the microwave if possible — it can make the chicken rubbery.
- Freezing: These freeze well before cooking. Assemble the stuffed chicken breasts, place on a parchment-lined tray, and freeze until solid. Transfer to a freezer bag and freeze for up to 2 months. Thaw overnight in the fridge before searing and baking.
Frequently Asked Questions
Yes — stuff the chicken breasts up to 24 hours ahead and store them covered in the fridge. Season and sear just before cooking. This actually makes weeknight prep even faster.
Yes — sear the chicken in a regular skillet, then transfer to a baking dish to finish in the oven. You’ll lose some of the pan juices but the chicken will still be delicious.
Boursin is available in most grocery stores in the specialty cheese section, usually near brie and goat cheese. Look for the small rectangular package — the Garlic & Fine Herbs flavor is what we use here.

Creamy Spinach Stuffed Chicken Breast
Ingredients
For the chicken:
- 3 large boneless, skinless chicken breasts (2 pounds)
- 1 teaspoon salt
- ½ teaspoon black pepper
- ½ teaspoon garlic powder
- ½ teaspoon smoked paprika
- 1½ tablespoons olive oil
For the filling:
- 1 5.2 ounce package Boursin cheese (Garlic & Fine Herbs)
- 1½ cups baby spinach, chopped
- ¼ cup shredded mozzarella
- ¼ cup grated Parmesan
Instructions
- Preheat oven to 425°F.
- In a bowl, mix Boursin, spinach, mozzarella, and Parmesan until combined.
- Cut a pocket into each chicken breast (don’t cut all the way through). Divide filling evenly and stuff inside. Secure with toothpicks if needed.
- Season chicken all over with salt, pepper, garlic powder, and paprika.
- Heat olive oil in an oven-safe skillet over medium heat. Sear chicken 3–4 minutes per side until golden.
- Transfer skillet to oven and bake 10–15 minutes, until internal temperature reaches 165°F.
- Rest 5 minutes, then serve with pan juices.
Notes
- Use even-sized chicken breasts: This helps everything cook at the same rate so you don’t end up with dry or undercooked pieces.
- Don’t cut all the way through: Slice a deep pocket, but keep the sides intact so the filling stays inside.
- Chill the filling (optional): If it feels too soft, refrigerate for 10–15 minutes to make stuffing easier.
- Don’t skip the sear: That golden crust adds a lot of flavor and helps lock in juices.
- Use an oven-safe skillet: It makes the transition from stovetop to oven seamless and keeps all those flavorful juices.
