Ingredient Notes & Details

Boneless, Skinless Chicken Breasts
Lean and tender, chicken breasts work beautifully in this slow cooker chicken recipe. You can substitute boneless thighs for extra juiciness if preferred.

Marinara Sauce
Choose a high-quality marinara for the best flavor. A thick, rich sauce creates that classic baked chicken Parmesan-style feel. Look for one with minimal added sugar.

Garlic (Minced)
Fresh garlic adds depth and warmth. Garlic powder can work in a pinch, but fresh gives a brighter flavor.

Italian Seasoning
This blend of oregano, basil, thyme, and rosemary gives that classic oven roasted chicken vibe without turning on the oven.

Salt & Black Pepper
Simple but essential for bringing out the natural flavors of the chicken and sauce.

Shredded Mozzarella Cheese
Use whole milk mozzarella for the best melt and stretch. Fresh mozzarella slices can also be used for a more elevated feel.

Parmesan Cheese (Optional)
Adds a salty, nutty finish that enhances the cheesy mozzarella topping.

Fresh Basil (Optional Garnish)
A sprinkle of fresh basil brightens the entire dish and adds a pop of color.

Step-by-Step Instructions

Step 1: Prepare the Slow Cooker
Lightly spray your slow cooker insert with cooking spray or use a liner for easy cleanup.

Step 2: Season the Chicken
Pat the chicken breasts dry with paper towels. Season both sides with salt, black pepper, and Italian seasoning. This builds flavor right from the start.

Step 3: Add Sauce and Garlic
Spread a thin layer of marinara sauce on the bottom of the slow cooker. Place the seasoned chicken on top. Add minced garlic, then pour the remaining sauce over the chicken, making sure it’s fully covered.

Step 4: Slow Cook Until Tender
Cover and cook on LOW for 4–6 hours or HIGH for 2–3 hours. The chicken should reach an internal temperature of 165°F and be fork-tender.

Step 5: Add the Mozzarella
About 20–30 minutes before serving, sprinkle shredded mozzarella evenly over the chicken. Cover again and allow it to melt completely.

Step 6: Finish with Parmesan & Basil
If using, sprinkle freshly grated Parmesan and chopped basil just before serving.

The result? Tender chicken bathed in rich tomato sauce with perfectly melted, bubbly cheese on top — all without using the oven.
