This slow cooker 6-ingredient chicken parmesan-style recipe is my kind of weeknight magic: you literally pour a jar of store-bought marinara and just five more simple ingredients over raw chicken breasts in the slow cooker, then let it do its thing while you handle the rest of your day. It has all the cozy, cheesy, red-sauce vibes of chicken parmesan, but without the breading, frying, or standing over the stove.
I started making this on nights when I knew I’d walk in the door starving and wanting something that felt like a real dinner, not just a frozen pizza situation, and it quickly became one of those “never gets old” meals everyone is happy to see on repeat.
I usually spoon this saucy chicken over a big bowl of hot spaghetti or penne, then add a simple green salad and some garlic bread or buttered toast on the side. It’s also great over zucchini noodles or steamed broccoli if you’re trying to keep things lighter. For a more comforting, Midwest-style spread, serve it with buttered egg noodles and a side of green beans.
Leftovers make an amazing chicken parmesan-style sandwich: pile the shredded chicken and extra sauce onto a toasted hoagie roll, top with more cheese, and broil until melty.
Slow Cooker 6-Ingredient Chicken Parmesan-Style
Servings: 4
Ingredients
1 1/2 to 2 pounds boneless, skinless chicken breasts (about 3–4 medium)
1 (24-ounce) jar store-bought marinara sauce
1 teaspoon garlic powder
1 teaspoon dried Italian seasoning (or dried oregano)
1/2 teaspoon kosher salt (or to taste)
1 1/2 cups shredded mozzarella cheese
1/4 cup grated Parmesan cheese
Directions
Spray the inside of your slow cooker with nonstick cooking spray or lightly grease it with a bit of oil to help with cleanup.
Lay the raw chicken breasts in a single layer on the bottom of the slow cooker. It’s okay if they overlap a little, but try to keep them mostly flat so they cook evenly.
In a medium bowl, pour in the jar of marinara sauce. Stir in the garlic powder, dried Italian seasoning, and kosher salt until everything is well combined.
Pour the seasoned marinara sauce evenly over the raw chicken breasts in the slow cooker, making sure all of the chicken is covered in sauce.
Cover the slow cooker with the lid and cook on LOW for 4 to 5 hours, or on HIGH for 2 1/2 to 3 hours, until the chicken is cooked through and easily shreds with a fork.
Once the chicken is done, use two forks to gently shred or break apart the chicken breasts right in the slow cooker, mixing them into the marinara sauce so everything is well coated.
Sprinkle the shredded mozzarella cheese evenly over the top of the saucy chicken, then sprinkle the grated Parmesan cheese over the mozzarella.
Cover the slow cooker again and cook on LOW for an additional 10 to 15 minutes, or until the cheese is melted and gooey. If your slow cooker has a “warm” setting, you can switch to warm once the cheese is melted and hold it there until you’re ready to eat.
Taste the sauce and add a pinch more salt if needed. Serve the cheesy chicken and sauce over cooked pasta, rice, or veggies, spooning extra sauce and cheese over each serving.
Variations & Tips
To make this even more like classic chicken parmesan, you can stir in 1/2 cup of seasoned breadcrumbs right after shredding the chicken, then top with the cheese and let it melt; it gives a slightly thicker, more “casserole” feel. If you prefer whole chicken pieces instead of shredded, simply skip the shredding step and just spoon the sauce over the intact breasts before topping with cheese. For extra flavor, add a small sliced onion or a handful of sliced mushrooms under the chicken before pouring on the marinara (this technically adds ingredients, but they cook down into the sauce and are great for stretching the meal).
To lighten it up, use part-skim mozzarella and serve the chicken over roasted vegetables or spaghetti squash. If you like a little heat, sprinkle in 1/4 teaspoon red pepper flakes with the seasonings. This recipe also meal-preps well: cook as directed, cool, then portion the cheesy chicken and sauce into containers with cooked pasta or rice for grab-and-go lunches that reheat beautifully in the microwave.
