Ingredients Overview
This recipe uses classic Italian-inspired staples to create a colorful, satisfying dish without a lot of fuss.
Main Ingredients:
-
Boneless Skinless Chicken Breasts: Choose medium to large breasts that can be butterflied or sliced for stuffing.
-
Pesto: Homemade or store-bought basil pesto adds aromatic, garlicky flavor and keeps the chicken moist during baking.
-
Fresh Mozzarella: Sliced mozzarella melts beautifully inside the chicken for a gooey center. You can also use mozzarella pearls or shredded.
-
Tomatoes: Cherry or grape tomatoes work well — their sweetness intensifies as they roast. Sun-dried tomatoes are also a great variation.
-
Olive Oil: Adds richness and helps the chicken brown.
-
Salt & Pepper: Simple seasoning that lets the pesto shine.
-
Italian Seasoning (Optional): A pinch sprinkled on top boosts the savory aroma.
Optional Additions:
-
Spinach or Arugula: Layer inside for added nutrients and texture.
-
Parmesan Cheese: A sprinkle on top before baking for an extra cheesy crust.
-
Toothpicks or Kitchen Twine: Useful for securing stuffed chicken, especially if overfilled.
Ingredient Tips:
-
Pesto: Use one with quality olive oil and real Parmesan. If homemade, store leftovers in the fridge or freezer.
-
Chicken: Pound slightly to even thickness if one side is much thicker.
-
Mozzarella: Fresh slices are best, but low-moisture shredded can also work if that’s what you have on hand.
Step-by-Step Instructions
1. Prep the Chicken
Preheat oven to 400°F (200°C).
Using a sharp knife, carefully slice a deep pocket into the side of each chicken breast. Don’t cut all the way through — you want to create a pouch.
Season both sides of the chicken breasts with salt and pepper.
2. Stuff the Chicken
Open the pocket and layer inside:
-
1–2 teaspoons pesto
-
1–2 slices fresh mozzarella
-
A few slices of cherry tomatoes or 2–3 sun-dried tomato pieces
Carefully press closed. Secure with toothpicks if needed.
Repeat with all chicken breasts.
3. Sear (Optional but Recommended)
In an oven-safe skillet, heat 1 tablespoon olive oil over medium-high heat.
Add chicken breasts and sear 2–3 minutes per side until lightly golden. This adds flavor and color.
If not searing, just place stuffed chicken directly in a greased baking dish.
4. Bake
Transfer skillet or dish to the oven and bake uncovered for 18–22 minutes, or until internal temperature reaches 165°F (74°C) and cheese is melted.
Optional: Broil for 2 minutes at the end for golden bubbly cheese.
Let rest 5 minutes before serving to retain juices.
Tips, Variations & Substitutions
-
Make It Low-Carb/Keto: This dish is naturally low in carbs. Serve with cauliflower mash or zucchini noodles.
-
Add Greens: Layer spinach or arugula inside the chicken for a pop of color and added nutrients.
-
Use Thighs Instead: Boneless thighs can also be stuffed and baked for a juicier option. Roll and secure with toothpicks.

Flavor Variations:
-
Swap pesto for sun-dried tomato pesto or olive tapenade

FAQs
Q1: Can I prep this in advance?
Yes! Stuff and season the chicken up to 24 hours in advance. Keep tightly covered in the fridge and bake when ready.
Q2: Can I freeze stuffed chicken breasts?
Yes, but for best results, freeze before baking. Wrap tightly and freeze up to 2 months. Thaw in the fridge overnight before cooking.
Q3: What kind of pesto is best?
Classic basil pesto works beautifully, but you can also try arugula pesto, kale pesto, or even sun-dried tomato pesto for a twist.
Q4: Can I make this dairy-free?
Yes. Use dairy-free pesto and a plant-based mozzarella alternative. There are many melty vegan cheeses available now.
Q5: Should I use toothpicks to keep them closed?
It helps, especially if overfilled. Be sure to remove toothpicks before serving.
Q6: How do I keep the chicken juicy?
Don’t overcook — check with a thermometer and let it rest before slicing. Also, searing the chicken helps lock in moisture.
Q7: What sides go best with this dish?
Fresh sides like arugula salad or grilled vegetables balance the richness. Or go classic with mashed potatoes or herbed rice.
