Ingredients for Mozzarella Chicken Skillet
I always use fresh mozzarella when possible because it melts beautifully and adds that authentic Italian touch. However, shredded mozzarella works perfectly fine if that’s what you have on hand. The key is using quality ingredients since this recipe keeps things simple.
- 2 tablespoons olive oil
- 1 onion, finely chopped
- 3-4 cloves garlic, minced or grated – I recommend using fresh garlic rather than jarred for the best flavor
- 1 (15 oz) can crushed tomatoes or your favorite marinara
- 1 teaspoon Italian seasoning
- 1/2 teaspoon garlic powder
- 1/2 teaspoon crushed red pepper – my preference is to adjust this based on your heat tolerance
- 1/2 teaspoon salt
- 1/2 teaspoon pepper
- 4 small-medium boneless, skinless chicken breasts – in my experience, pounding them to even thickness ensures consistent cooking
- 8 oz fresh or shredded mozzarella – I usually go for fresh mozzarella slices for that restaurant-style presentation
- Fresh basil, to garnish
Step-by-Step Instructions
I recommend having all your ingredients prepped before you start cooking. This recipe moves quickly once you begin, so having everything ready makes the process smooth and stress-free.
Step 1: Preheat your oven to 400°F. Heat the olive oil in a large oven-safe skillet over medium-high heat. Add the chopped onion and cook for 2-3 minutes until softened and the edges turn slightly golden. This caramelization adds wonderful depth to your sauce.
Step 2: Add the minced garlic and sauté for just 30 seconds, stirring constantly. Garlic burns quickly, so watch it closely. Once fragrant, add the crushed tomatoes along with Italian seasoning, garlic powder, crushed red pepper, salt, and pepper. Sauté everything together for 2 minutes to let the flavors meld.
Step 3: Pat the chicken breasts dry with paper towels, then nestle them into the tomato sauce. Cook for 1-2 minutes per side. You’re not cooking them through at this stage, just giving them a quick sear to lock in moisture and add color.
Step 4: Transfer the skillet to your preheated oven and bake for 10 minutes. Remove the pan carefully (use oven mitts as the handle will be extremely hot), flip each chicken breast, then top with mozzarella slices or shredded cheese. Return to the oven and bake another 10 minutes until the chicken reaches an internal temperature of 165°F. The cheese should be golden and bubbly.
Step 5: Remove from the oven and let rest for 2-3 minutes. Garnish with fresh basil leaves and serve immediately while the cheese is still gooey and delicious.

Perfect Pairings for Your Cheesy Chicken Skillet
This Italian-inspired chicken pairs beautifully with sides that complement its rich, savory flavors while adding variety to your plate.
Zucchini Noodles: Perfect for keeping this meal low-carb and keto-friendly. The light, fresh taste of zoodles balances the rich cheese and tomato sauce without overwhelming your palate. They soak up the delicious sauce beautifully.
Garlic Roasted Broccoli: Try this alongside our Sheet Pan Garlic Butter Chicken and Veggies for a complete one-pan approach. The slight bitterness of roasted broccoli cuts through the richness of the cheese while adding essential vitamins and fiber to your meal.
Cauliflower Rice: Another fantastic low-carb option that soaks up the delicious tomato sauce. Season it with a bit of garlic and herbs to complement the Italian flavors in the main dish. For another rice-based meal, check out our Smothered Chicken and Rice.
Simple Green Salad: A crisp salad with lemon vinaigrette provides a refreshing contrast to the warm, cheesy chicken. The acidity brightens up the entire meal and adds nutritional balance. If you love Italian flavors, our Creamy Garlic Parmesan Chicken Pasta makes another excellent pairing.
Garlic Bread: If you’re not watching carbs, a slice of warm garlic bread is perfect for sopping up every last bit of that incredible tomato sauce. It’s comfort food at its finest, similar to what you’d enjoy with our Spinach and Ricotta Stuffed Shells.
Keeping It Fresh
Store any leftovers in an airtight container in the refrigerator for up to 3-4 days. The flavors actually deepen overnight, making leftovers even more delicious the next day.
To reheat, I recommend using a covered skillet over medium-low heat to preserve the chicken’s moisture. Add a splash of water or chicken broth if the sauce has thickened. You can also microwave individual portions, though the chicken may be slightly less tender than skillet reheating.
This dish is incredibly versatile. Shred any leftover chicken and toss it with pasta for a quick lunch, or serve it over rice for a different spin on the original recipe. For more chicken dinner inspiration, try our Mozzarella Chicken in Basil Cream Sauce or Chicken Marsala.
FAQs
Can I use chicken thighs instead of breasts?
Absolutely! Chicken thighs work wonderfully and add extra richness. Just adjust the cooking time slightly as thighs may need a few extra minutes to reach 165°F.
What if I don’t have an oven-safe skillet?
You can sear the chicken in a regular skillet, then transfer everything to a baking dish before placing it in the oven. Just be sure to use a dish large enough to hold the chicken in a single layer.
Can I make this ahead of time?
You can prep the sauce and sear the chicken a few hours ahead, then refrigerate. When ready to serve, bring to room temperature and complete the baking steps as directed.
