Mozzarella Pesto Stuffed Chicken

The smell of basil pesto bubbling under golden chicken still makes my stomach rumble. I stumbled on this technique during a chaotic Tuesday when I needed something impressive but fast, and my brother was coming over unexpectedly. The way the mozzarella oozes out when you cut into it feels like a tiny celebration every single time.

Last summer I made this for my neighbor who swears she hates boring chicken breast. She literally asked for the recipe before even finishing her first bite, and now she makes it twice a week for her family. The cheese melting into the pesto creates this incredible sauce that forms right in the pan.

Ingredients

• 4 boneless skinless chicken breasts: Look for pieces of similar size so they finish cooking together
• 1 tablespoon olive oil: Helps the seasonings stick and creates that gorgeous golden exterior
• 1/2 teaspoon salt: Essential even with the salty pesto inside
• 1/4 teaspoon black pepper: Freshly cracked makes such a difference here
• 4 tablespoons basil pesto: Homemade is lovely but good store bought works perfectly too
• 120 g mozzarella cheese sliced: Fresh mozzarella melts beautifully but low moisture slices work best
• 2 tablespoons grated Parmesan cheese: Forms this incredible salty crust on top
• 1/2 teaspoon dried Italian herbs: Totally optional but pretty and fragrant

Instructions

Preheat your oven to 200°C 400°F and grease a baking dish:

Do not skip greasing the pan because the cheese will stick and create a mess

Carefully cut a deep pocket into each chicken breast:

Go slowly and keep your hand flat on top of the chicken to guide the knife through without piercing the back

Season the chicken generously on all sides:

Get the salt and pepper into the pockets too not just the outside

Fill each pocket with pesto and mozzarella:

Do not overstuff or the cheese will escape during baking

Secure openings with toothpicks and brush with oil:

Place them seam side up in the dish so the cheese stays put while cooking

Sprinkle with Parmesan and Italian herbs:

This creates the most beautiful golden crust that everyone will notice

Bake for 25 to 30 minutes until fully cooked:

The juices should run clear and an instant read thermometer must hit 74°C

Let the chicken rest for 5 minutes before serving:

This keeps all those juices inside instead of running onto your cutting board

My husband requests this whenever we have friends over for dinner because it looks fancy but requires almost no active cooking time. I love that I can prep everything in the morning and just pop it in the oven when guests arrive.

Making It Your Own

Sun dried tomato pesto works beautifully here and adds this gorgeous red color throughout the filling. Sometimes I add a few fresh spinach leaves inside the pockets because they wilt down and add a nice contrast to the rich cheese.

What To Serve Alongside

Roasted vegetables with some olive oil and salt make the perfect side because they cook right alongside the chicken. A crisp green salad with a simple vinaigrette cuts through the richness beautifully.

Wine Pairing Secrets

A light Italian white wine like Pinot Grigio complements the basil without overpowering it. The crisp acidity balances the rich cheese filling perfectly.

• Chill your wine properly before serving
• Avoid heavily oaked whites that compete with the pesto
• Light red wines work too if you prefer red over white

This is one of those recipes that somehow manages to feel elegant and comforting all at once.

Recipe Questions & Answers

→ How do I prevent the filling from leaking out?

Use toothpicks to secure the opening after stuffing. You can also lightly pound the chicken to an even thickness before cutting the pocket, which helps create a tighter seal. Place the chicken seam-side up in the baking dish.

→ Can I use store-bought pesto?

Absolutely. Store-bought basil pesto works perfectly and saves time. Just check the ingredients to ensure it meets your dietary needs, especially if avoiding nuts or specific allergens.

→ What internal temperature should the chicken reach?

The chicken is safe when it reaches 74°C (165°F) internally. Use a meat thermometer inserted into the thickest part, avoiding the filling, to ensure doneness without overcooking.

→ Can I prepare this ahead of time?

Yes, you can stuff the chicken up to 24 hours in advance. Wrap tightly and refrigerate until ready to bake. You may need to add 5-10 minutes to the cooking time if baking cold from the refrigerator.

→ What sides pair well with this dish?

Roasted vegetables like zucchini, bell peppers, or asparagus complement the flavors beautifully. A crisp green salad with balsamic dressing, cauliflower mash, or steamed green beans also work wonderfully.
