Ingredients

• 24 to 32 ounces boneless and skinless chicken breasts
• 1 yellow summer squash, small, cut into 1/4 inch circles

• 1 tablespoon olive oil
• 3 garlic cloves, minced
• 1/2 teaspoon kosher salt
• 1/4 teaspoon ground black pepper

Make-ahead and serving ideas

This dish holds up well if you want to prepare the filling a few hours in advance: keep the sautéed vegetables refrigerated and assemble just before cooking. Serve the stuffed chicken over a bed of steamed rice, alongside a simple green salad, or with crusty bread to sop up any juices. A light drizzle of extra virgin olive oil and a squeeze of lemon over the plated chicken brightens the flavors beautifully.

Equipment

• Cutting board and sharp knife
• Large skillet (ovenproof if you want to finish in the oven) or a baking dish
• Tongs or spatula
• Meat thermometer (recommended)

Step-by-step instructions

Follow these steps to make Cheesy Summer Squash Stuffed Chicken. The rewritten directions preserve the original order and ingredient amounts while clarifying each step for a smooth cooking experience.

1. Prepare the vegetables: Slice the yellow summer squash, zucchini, and roma tomatoes into 1/4 inch circles. Mince the garlic cloves and set everything aside.
2. Make the filling: Heat 1 tablespoon olive oil in a large skillet over medium heat. Add the minced garlic and cook for about 30 seconds to 1 minute, stirring, until fragrant but not browned.
3. Add the sliced yellow summer squash and zucchini to the skillet. Sauté for 4 to 6 minutes, stirring occasionally, until the vegetables are slightly softened but still hold their shape.
4. Stir in the sliced roma tomatoes and continue to cook for another 1 to 2 minutes, just until the tomatoes begin to warm through. Remove the skillet from the heat and season the vegetable mixture with 1/2 teaspoon kosher salt and 1/4 teaspoon ground black pepper. Allow the filling to cool slightly so it’s easier to handle.
5. Prepare the chicken breasts: Pat the 24 to 32 ounces boneless and skinless chicken breasts dry with paper towels. Using a sharp knife, carefully cut a pocket into the thickest side of each chicken breast by slicing horizontally, leaving about 1/2 inch of meat intact at the edges so the pocket holds together. Do not cut all the way through.
6. Stuff the chicken: Spoon an even amount of the cooled vegetable mixture into each chicken breast pocket. Divide the 1/2 cup shredded mozzarella cheese among the breasts, tucking it into the pocket on top of the vegetables so the cheese will melt inside while the chicken cooks. Press the edges gently to close the pockets. If needed, secure with toothpicks to hold the opening closed while cooking.
7. Cook the chicken: Wipe the skillet clean and return it to medium heat with a small splash of olive oil if needed. Place the stuffed chicken breasts in the skillet and sear for 3 to 4 minutes on the first side without moving them, until golden brown. Carefully flip each breast and sear the second side for another 3 to 4 minutes.
8. Finish cooking through: Reduce the heat to medium-low and cover the skillet, or transfer the seared chicken to a baking dish and place it in a preheated 375°F oven. Continue cooking until the chicken reaches an internal temperature of 165°F in the thickest part of the breast and the cheese inside has melted, about 6 to 12 minutes depending on thickness. Use a meat thermometer to confirm doneness for perfectly cooked chicken.
9. Rest and serve: Remove the chicken from the heat and let it rest for 3 to 5 minutes to allow the juices to redistribute. Remove any toothpicks if used. Slice each breast to reveal the cheesy, vegetable-studded interior and serve warm.

Troubleshooting & tips

• If the chicken browns too quickly before it’s cooked through, lower the heat and cover the skillet to finish cooking more gently.
• If your chicken breasts are very thick, consider butterflying them more thinly or pounding them slightly to an even thickness so they cook evenly.
• To avoid a watery filling, cook the vegetables just until tender and let them cool before stuffing; excess moisture releases during cooking otherwise.
• For extra flavor, add a pinch of dried oregano or 1 teaspoon chopped fresh basil to the vegetable mixture.

Nutritional notes

This Cheesy Summer Squash Stuffed Chicken is a moderate-calorie entrée that highlights vegetables while keeping the cheese portion light. Using fat-free shredded mozzarella reduces saturated fat while still delivering that satisfying melty texture. Pair with whole grains or a simple side salad for a balanced plate.

Leftover storage and reheating

Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently in a 350°F oven for 10 to 12 minutes or until warmed through, or microwave on medium power in 30-second increments to avoid drying out the chicken. If reheating from chilled, bring to room temperature for 10 to 15 minutes before reheating for more even warming.

Final thoughts

Cheesy Summer Squash Stuffed Chicken is a breezy, vegetable-forward way to enjoy boneless, skinless chicken breasts.

Once you get the hang of pocketing and stuffing the chicken, this recipe is easy to adapt and a reliable go-to for seasonal meals.
