Boursin Stuffed Chicken

This is the kind of dinner that works on a Tuesday but impresses at a dinner party. Chicken breasts stuffed with creamy Boursin, mozzarella, and spinach, seared golden and finished in a hot oven, so they cut open at the table like something from a restaurant. The first time I made stuffed chicken, I used fresh spinach without squeezing out the water, and the filling turned loose and watery and leaked everywhere. Using frozen spinach squeezed bone-dry fixes that completely.

What I love is the dramatic payoff for how little work it actually takes. One pan, about thirty minutes, and a crisp golden crust with a gooey, herby center. The Boursin is the flavor backbone, the mozzarella makes it stretchy and gooey, and a little Italian seasoning and garlic powder amplify it all. It looks like you really did something, and you did, it just wasn’t that hard.

Here’s the kitchen tip for the crust. Sear the chicken first, at high heat, for a full five minutes without moving it. That’s what builds the deeply golden crust. If you keep nudging it around, it never browns properly, so place it top-side down and leave it alone. Then it goes straight into a hot 425 oven to finish, and the high heat means a short cook time, which keeps the chicken juicy instead of drying out.

And cut the pocket like a pita pocket, not a butterfly, which is the part that looks intimidating but isn’t. Cut into the thick side of the breast, starting in the center, and go about three-quarters of the way through, leaving about 3/4 inch on both ends so the pocket has walls. You’re making a pouch, not opening the breast flat. Go slow with a sharp knife, and if you nick through one end, that’s what the toothpicks are for. You’ll smell that garlicky, herby cheese thing as it cooks.

Why You’ll Love This Recipe

The crust is crisp and golden. Searing first at high heat builds a deeply golden crust before the chicken finishes in the oven.

The filling is gooey and herby. Boursin, mozzarella, and spinach make a creamy, stretchy center packed with flavor.

It’s restaurant-caliber. It cuts open at the table looking impressive, even though it’s a one-pan, 30-minute dinner.

It’s make-ahead friendly. You can stuff the chicken ahead and just sear and bake when you’re ready.

Ingredients

Here’s everything you’ll need:

• 1 1/2 lbs boneless skinless chicken breasts
• 1/4 cup frozen spinach, thawed
• 1 cup low-moisture shredded mozzarella
• 1 teaspoon Italian seasoning
• 1 teaspoon garlic powder
• 1 (5oz) wheel garlic herb Boursin cheese
• 1 teaspoon kosher salt
• Black pepper, to taste
• 1 Tablespoon olive oil

How to Make Boursin Stuffed Chicken

1. Prep the Chicken

Heat the oven to 425. Place the chicken breasts between parchment and gently pound the centers to an even thickness, not thin, just even. Pat them completely dry with paper towels for a better sear.

2. Cut the Pockets

Lay each breast flat and cut into the thick side, starting at the center, almost all the way through, leaving about 3/4 inch on each end. Think pita pocket, not butterfly, so you’re making a pouch.

3. Make the Filling

Squeeze every bit of moisture out of the thawed spinach with a paper towel. Mix it with the mozzarella, Italian seasoning, garlic powder, and Boursin until combined. It should be thick and hold its shape.

4. Stuff and Seal

Spoon the filling evenly into each pocket without overfilling. Push two toothpicks through both sides to close the seam, then season the outside generously with salt and pepper.

5. Sear the Chicken

Heat the olive oil in a large oven-safe skillet over medium-high until shimmering. Place the chicken top-side down and cook five minutes without moving it, then flip and sear two to three minutes more, until deeply golden.

6. Finish in the Oven

Transfer the pan to the oven and bake 10 to 12 minutes, until the internal temperature hits 165 degrees. Rest five minutes, then remove the toothpicks before plating.

Expert Tips

Sear without moving the chicken. A full five minutes undisturbed is what builds that golden crust.

Use frozen spinach squeezed dry. Any moisture left makes the filling loose and watery.

Cut a pita pocket, not a butterfly. You want a deep pouch with walls, not the breast opened flat.

Use low-moisture mozzarella. Fresh mozzarella has too much water and won’t get that gooey stretch.

Pat the chicken dry before searing. A dry surface browns much better than a wet one.

Recipe Variations and Add-ins

You can use homemade Boursin cheese in place of the store-bought wheel.

Add a few chopped sun-dried tomatoes to the filling for a tangy, sweet note.

You can use a different herb Boursin flavor like shallot and chive to change it up.

Wrap each stuffed breast in a slice of prosciutto before searing for a salty, crispy edge.

You can add a pinch of red pepper flakes to the filling for a little heat.

What to Serve With This Recipe

Serve it with roasted green beans. Toss them on a sheet pan to finish alongside the chicken. The two come together easily.

Pair it with Boursin mashed potatoes. The creamy potatoes echo the filling. They make a hearty plate.

Set it next to roasted baby potatoes. The crisp potatoes round out the meal. They roast right with the chicken.

How to Store This Recipe

This is a great recipe to prep ahead. Stuff the chicken, seal with toothpicks, cover tightly with plastic wrap, and refrigerate for up to 24 hours, then sear and bake when ready, adding two to three minutes to the oven time since it’s going in cold.

Store cooked leftovers in an airtight container in the fridge for a few days. Reheat in the oven to keep the crust from going soft, since the microwave can leave the chicken rubbery.
