Ingredients Overview

Let’s break down the essential ingredients that make this stuffed chicken dish so irresistible:

Chicken Breasts

Choose boneless, skinless chicken breasts, preferably thick ones. These hold up well to stuffing and stay juicy when baked. If they’re very large, slice them in half to create uniform portions.

Fresh Mozzarella

Soft, fresh mozzarella adds creaminess and that signature cheesy pull. You can use mozzarella balls, pre-sliced rounds, or shred a block of low-moisture mozzarella.

Cherry or Grape Tomatoes

These mini tomatoes are juicy and sweet, and their small size makes them perfect for stuffing without adding too much moisture. Halve them to prevent the filling from becoming watery.

Basil Pesto

Pesto is the flavor backbone here. Whether you use store-bought or homemade, it brings richness, garlic, and herby brightness to the dish. A little goes a long way.

Olive Oil

Used for searing and baking. Go for extra virgin olive oil for the best flavor.

Seasonings

Salt, pepper, garlic powder, and Italian seasoning elevate the chicken without overpowering the filling.

Toothpicks or Kitchen Twine

Used to secure the chicken so the filling doesn’t spill out during cooking.

Step-by-Step Instructions

This recipe comes together in under 40 minutes and looks much fancier than it is. Here’s how to make it:

1. Preheat Oven

Preheat your oven to 375°F (190°C). Lightly grease a baking dish or ovenproof skillet.

2. Prepare the Chicken

• Place 4 chicken breasts on a cutting board.

• Using a sharp knife, slice a pocket into the side of each chicken breast, being careful not to cut all the way through.

• Season the outside and inside of each pocket with salt, pepper, garlic powder, and Italian seasoning.

3. Add the Filling

• Spread 1 tablespoon of pesto inside each chicken pocket.

• Stuff with 2–3 slices of mozzarella and 3–4 halved cherry tomatoes.

• Secure the opening with toothpicks to keep the filling in place during cooking.

4. Sear the Chicken (Optional but Recommended)

• Heat 1–2 tbsp olive oil in a large oven-safe skillet over medium-high heat.

• Add the stuffed chicken and sear for 2–3 minutes per side, until golden brown. This helps lock in flavor and gives the chicken a beautiful color.

5. Bake

• Transfer the skillet to the oven (or place chicken in your prepared baking dish).

• Bake for 18–22 minutes, or until the internal temperature reaches 165°F (74°C).

• Let rest for 5 minutes before removing toothpicks and serving.

FAQ

1. Can I use frozen chicken?

Yes, but thaw it fully before slicing and stuffing. Frozen chicken can be harder to cut and will cook unevenly if not fully thawed.

2. Can I make this ahead of time?

Absolutely. Assemble the chicken, cover, and refrigerate for up to 24 hours. Bake just before serving.

3. Can I air fry these?

Yes! Air fry at 375°F (190°C) for 15–18 minutes, flipping halfway. Use toothpicks to secure the stuffing, and lightly spray with oil for a golden crust.

4. Can I grill the stuffed chicken?

You can, but it’s best to use indirect heat and keep the lid closed to avoid burning the outside while the inside cooks. Wrapping in foil can help retain the filling.

5. How do I prevent the stuffing from leaking out?

Secure the opening with 2–3 toothpicks, and don’t overstuff. Searing before baking also helps seal the chicken.

6. What’s the best way to reheat leftovers?

Reheat gently in the oven at 325°F (160°C) for 10–12 minutes or in the microwave in 30-second bursts, covered with a damp paper towel.

7. Is this recipe good for meal prep?

Yes. It keeps well for up to 4 days in the fridge. Just let it cool fully before storing in airtight containers.
