One-Pan Chicken

This pesto-stuffed chicken is layered with mozzarella and a bright pistachio-pea pesto, seared in a cast-iron skillet, then baked to an internal temperature of 165°F for a juicy finish. Stuffed chicken often dries out, but following these steps—searing first, monitoring temperature, and finishing in the oven—gives you tender chicken, a crisp exterior, and a vibrant filling.

The whole recipe cooks in a single cast-iron pan in under 30 minutes. Serve with green beans, Italian Lacinato Kale, or Crispy Garlic Parmesan Potatoes for a complete meal.

Ingredients Notes and Substitutions

Ingredients for the recipe.
  • Pesto. Any pesto works here: classic Genovese, trapanese, or an easy pistachio-pea pesto. Use your favorite flavor profile.
  • Cast Iron Pan. A cast iron skillet gives the best sear, but an oven-proof stainless pan works too. If your pan isn’t oven-safe, transfer the seared chicken to a baking dish before finishing in the oven.
  • Peas and Basil. If basil is scarce, increase the peas in the pesto. Use as much fresh basil as available for the brightest flavor.

How to Make Pesto Stuffed Chicken

Ingredients for pesto in a food processor.

Step 1: Make the pesto first. Combine peas, basil, garlic, and pistachios in a food processor and blend until the peas are broken down. Add lemon juice and salt, then process while slowly streaming in olive oil until incorporated.

Step 2: Add grated Parmesan to the pesto and pulse to combine. Add a bit more olive oil if needed for a spoonable consistency. If you’re using store-bought pesto, skip steps 1–2.

Step 3: Preheat the oven to 375°F. Butterfly each chicken breast in thirds: slice thinly to create two pockets while keeping the outer edge intact, producing two openings per breast for stuffing.

Step 4: Spread pesto into each pocket, stuff with mozzarella, fold the chicken closed, and season both sides with salt and pepper.

Step 5: Heat a cast iron skillet over medium-high heat and add avocado or extra virgin olive oil. When the pan is hot, place the chicken in the skillet and sear 3–4 minutes per side until golden.

Step 6: Transfer the skillet to the preheated oven and bake about 15 minutes, or until the internal temperature reaches 165°F. Let rest briefly before serving.

Pro-Tips

  1. Use an instant-read thermometer. Ovens and chicken pieces vary. Checking temperature is the best way to avoid overcooking and ensure moist, safe chicken.
  2. Sear properly. Wait until the pan is hot and nearly smoking, then add the chicken and sear undisturbed for about 3 minutes before flipping to build a good crust.
  3. Butterfly in thirds for better ratio. Cutting two pockets gives more surface area for pesto and cheese so the filling isn’t overwhelmed by the meat. That creates a better pesto-to-chicken balance than a single cut.

Recipe FAQs

How do you reheat stuffed chicken?

Microwave reheating is often the gentlest option for leftover stuffed chicken; reheating in the oven can dry it out. Reheat briefly, checking frequently for even warming.

What vegetables pair well with pesto chicken?

Light vegetables and salads work well—think green beans, sautéed greens, or a simple salad dressed with a classic Caesar or an Italian-style cabbage slaw.

Why sear before baking?

Searing seals the exterior, helps retain juices while baking, and creates a flavorful crust that contrasts the tender interior.

Notes

  1. The pistachio-pea pesto freezes well—make extra for later use.
  2. Always use an instant-read thermometer to ensure the chicken reaches 165°F without overcooking.
  3. When searing, wait until the pan is hot and barely smoking, then sear for about 3 minutes undisturbed before flipping.
  4. Butterflying the chicken into two pockets improves the pesto-to-chicken ratio and gives a better filling experience.
