Why You’ll Love This Slow Cooker Chicken Parmesan

• Easy weeknight dinner: Minimal prep and simple pantry ingredients.
• No frying required: Enjoy chicken parmesan-style flavor without breading or oil-heavy cooking.
• Family-friendly recipe: Cheesy marinara chicken is a favorite with both kids and adults.
• Great for meal prep: Leftovers reheat well for lunches, pasta bowls, sandwiches, or wraps.
• High-protein meal: Chicken breasts provide protein, while tomato-based marinara adds flavor with minimal effort.

Ingredients

• 1½ to 2 pounds boneless, skinless chicken breasts
• 1 jar (24 ounces) marinara sauce
• 1 teaspoon garlic powder
• 1 teaspoon dried Italian seasoning or dried oregano
• ½ teaspoon kosher salt, or to taste
• 1½ cups shredded mozzarella cheese
• ¼ cup grated Parmesan cheese

Instructions

1. Lightly grease the inside of your slow cooker with oil or nonstick cooking spray.
2. Place the chicken breasts in a single layer at the bottom of the slow cooker. A little overlap is fine, but try to keep the chicken mostly flat for even cooking.
3. In a bowl, combine the marinara sauce, garlic powder, Italian seasoning, and salt. Stir until well mixed.
4. Pour the seasoned marinara sauce over the chicken breasts, making sure the chicken is fully covered.
5. Cover and cook on LOW for 4 to 5 hours or on HIGH for 2½ to 3 hours, until the chicken is tender and fully cooked.
6. Use two forks to shred the chicken directly in the slow cooker. Mix it well with the marinara sauce.
7. Sprinkle mozzarella cheese over the chicken and sauce, followed by the grated Parmesan.
8. Cover again and cook on LOW for 10 to 15 minutes, until the cheese is melted, creamy, and bubbly.
9. Serve hot with pasta, rice, steamed vegetables, spaghetti squash, or a fresh green salad.

Serving Ideas

Serve this cheesy slow cooker chicken over spaghetti, penne pasta, buttered egg noodles, or fluffy rice. For a lighter meal, pair it with zucchini noodles, roasted broccoli, green beans, or spaghetti squash.

It also makes a delicious chicken parmesan-style sandwich. Spoon the shredded chicken and sauce onto toasted rolls, add extra mozzarella, and broil until melted.

Tips and Variations

For a thicker, casserole-style texture, stir in ½ cup seasoned breadcrumbs after shredding the chicken, then add the cheese. To keep the chicken breasts whole, skip shredding and simply top each breast with sauce and cheese.

You can also add sliced mushrooms or onions beneath the chicken for extra flavor. For a spicy version, add a pinch of red pepper flakes to the marinara sauce. Use part-skim mozzarella and serve with vegetables for a lighter slow cooker chicken parmesan meal.

Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently in the microwave or on the stovetop with a splash of marinara sauce if needed.
