Slow Cooker Cheesy Mozzarella Chicken Recipe

Looking for a comforting, cheesy, and flavorful dish that practically cooks itself? Look no further than this Slow Cooker Cheesy Mozzarella Chicken. It’s a cozy, Italian-inspired meal that’s simple enough for a weeknight yet satisfying enough for company. Imagine tender chicken breasts slow-cooked in a rich tomato sauce, topped with gooey mozzarella cheese—like a lazy-day version of chicken parmesan, but even creamier and easier.

Step-by-Step Instructions

Step 1: Prepare the Chicken

Pat chicken dry with paper towels. Season both sides with salt, pepper, garlic powder, and Italian seasoning.

Optional: For added depth of flavor, sear the chicken breasts for 2–3 minutes per side in olive oil in a hot skillet. This adds a caramelized exterior that enhances the overall dish, but it’s not required.

Step 2: Prepare the Sauce

In a mixing bowl or directly in the slow cooker, combine the marinara sauce, onion, garlic, basil, oregano, red pepper flakes, tomato paste, and sugar. Stir well to combine.

Taste and adjust seasoning if needed. If you’re using a pre-made marinara, you may not need much salt or sugar.

Step 3: Add Chicken to the Slow Cooker

Place the seasoned chicken into the slow cooker. Pour the sauce mixture over the chicken, making sure all pieces are coated and submerged.

Step 4: Slow Cook

Set your slow cooker to:

• Low for 6–7 hours for juicy, tender chicken

• High for 3–4 hours for a faster meal

Avoid overcooking, especially if using chicken breasts, as they can become dry. Chicken thighs offer a little more leeway in cooking time.

Step 5: Add the Cheese

About 15–30 minutes before serving, sprinkle shredded mozzarella and Parmesan evenly over the top of the chicken. Cover and cook on low or warm until the cheese is melted and bubbly.

Step 6: Garnish and Serve

Once the cheese is melted, garnish with freshly chopped basil or parsley.

Use a spatula to lift each cheesy chicken portion and serve hot with your favorite sides.

Serving Suggestions

This cheesy chicken pairs wonderfully with both classic and creative sides:

Carbohydrate Bases:

• Pasta – spaghetti, penne, or fettuccine are perfect

• Rice – white, brown, or garlic butter rice

• Mashed potatoes – adds a creamy, rich contrast

• Polenta – for a rustic, Italian-inspired plate

• Toasted ciabatta or garlic bread – soak up every drop of sauce

Vegetable Sides:

• Roasted broccoli or cauliflower

• Steamed green beans with lemon zest

• Italian salad with vinaigrette

• Roasted zucchini, eggplant, or bell peppers

Tips for Success

1. Chicken Cut Options

• Thighs stay moist longer and are less prone to drying out in the slow cooker.

• Breasts are leaner and better for lower-fat diets but must be watched carefully to avoid overcooking.

2. Sauce Consistency

If you like a thicker sauce, you can:

• Use tomato paste or a thicker marinara

• Remove the lid for the last 30 minutes to reduce the sauce

3. Cheese Tips

• Use whole milk mozzarella for maximum melt and flavor

• Grate your own cheese—pre-shredded cheese contains anti-caking agents that affect meltability

4. Meal Prep

• Make this a freezer meal by adding seasoned raw chicken and sauce to a freezer bag. Freeze flat. Thaw in the fridge overnight before adding to your slow cooker the next day.

Variations

1. Creamy Mozzarella Chicken

Add ½ cup of heavy cream or cream cheese to the sauce for a creamier version. Stir it in during the last hour of cooking.

2. Mozzarella Chicken with Spinach

Stir in 2–3 cups of fresh baby spinach during the last 15 minutes of cooking. It wilts beautifully into the sauce and adds color and nutrients.

3. Spicy Mozzarella Chicken

Add an extra ½ teaspoon of red pepper flakes, or a dash of hot sauce to the sauce. Top with sliced jalapeños before serving.

4. Mozzarella Chicken with Mushrooms

Add 1 cup of sliced mushrooms at the beginning of the cook time for an umami boost.

5. Chicken Mozzarella Sandwiches

Shred the cooked chicken and serve it on toasted rolls with the sauce and cheese melted under a broiler. Add arugula or sautéed peppers for extra flavor.

Storage and Reheating

FAQs

Can I use frozen chicken in the slow cooker?

It’s best to thaw frozen chicken first to ensure safe and even cooking. USDA guidelines advise against cooking frozen meat directly in a slow cooker.

Can I make this dairy-free?

Yes, omit the cheese and consider adding a splash of coconut milk or dairy-free cream to the sauce for richness. Use a dairy-free cheese alternative if desired.

What’s the best slow cooker size for this recipe?

A 4 to 6-quart slow cooker is ideal. If doubling the recipe, use a larger size to avoid overcrowding.

Can I cook this on the stovetop or in the oven?

Yes! Simmer the sauce and chicken in a large skillet on low heat, covered, for 30–40 minutes. Top with cheese in the last 5 minutes, then cover again to melt.
