🛒 Ingredients
- 4 boneless, skinless chicken breasts
- 2 cups marinara or pasta sauce
- 1 cup shredded mozzarella cheese
- ½ cup grated Parmesan cheese
- 1 teaspoon Italian seasoning
- 1 teaspoon garlic powder
- ½ teaspoon salt
- ½ teaspoon black pepper
- ½ teaspoon paprika
- ½ cup breadcrumbs, preferably Italian-seasoned
- 2 tablespoons olive oil
- 1 tablespoon chopped fresh parsley, optional
- ½ teaspoon red pepper flakes, optional
- 8 oz spaghetti or your favorite pasta, for serving
👩🍳 Step-by-Step Instructions
Step 1: Prepare the Chicken
Pat the chicken breasts dry with paper towels. If the breasts are very thick, carefully cut them horizontally into thinner pieces so they cook more evenly.
Season both sides with:
- Salt
- Black pepper
- Garlic powder
- Paprika
- Italian seasoning
Rub the seasoning into the chicken so every piece is well coated.
Step 2: Prepare the Slow Cooker
Lightly spray the inside of your slow cooker with cooking spray or brush it with a little olive oil.
Pour about ½ cup of marinara sauce into the bottom of the slow cooker and spread it evenly.
This creates a flavorful base and helps prevent the chicken from sticking.
Step 3: Add the Chicken
Place the seasoned chicken breasts in the slow cooker in a single layer if possible.
Pour the remaining marinara sauce over the chicken, making sure the pieces are well covered.
If you like a little heat, sprinkle the red pepper flakes over the sauce.
Step 4: Slow Cook
Cover the slow cooker with the lid.
Cook on:
- LOW: 5–6 hours
- HIGH: 3–4 hours
Cooking time depends on the thickness of your chicken. The chicken is done when the center reaches 165°F / 74°C.
Try not to repeatedly open the lid while cooking because this allows heat to escape and can increase the cooking time.
Step 5: Add the Cheese
Once the chicken is fully cooked, sprinkle the Parmesan cheese evenly over the chicken.
Then cover each piece with shredded mozzarella.
Put the lid back on and cook for another 10–15 minutes, or until the mozzarella is completely melted.
For a more browned, bubbly cheese topping, you can carefully transfer the chicken to an oven-safe dish and place it under the broiler for a few minutes. Watch it closely because the cheese can brown quickly.
Step 6: Rest the Chicken
Turn off the slow cooker and let the chicken rest for about 5 minutes.
This helps the juices settle and makes the chicken easier to serve.
Sprinkle with fresh parsley for a bright, fresh finish.
Step 7: Prepare the Pasta
While the chicken is cooking—or shortly before serving—cook the spaghetti according to the package directions.
Drain the pasta and toss it with some of the warm marinara sauce from the slow cooker.
Step 8: Serve
Place spaghetti on each plate and top with a tender piece of Chicken Parmesan.
Spoon some extra marinara sauce over the chicken and pasta.
Finish with additional Parmesan and fresh parsley if desired.
🍝 What to Serve With It
Slow Cooker Chicken Parmesan goes especially well with:
- Spaghetti or fettuccine

- Roasted broccoli
- Steamed green beans
- Italian salad
- Roasted vegetables
For a complete busy-night dinner, spaghetti + Chicken Parmesan + garlic bread + simple green salad is an easy combination.
⭐ Tips for the Best Chicken Parmesan
Don’t overcook the chicken: Chicken breasts can become dry if left in the slow cooker too long. Start checking the temperature toward the lower end of the cooking range.
Use good marinara sauce: Since the sauce is a major part of the dish, a flavorful marinara makes a noticeable difference.
Use freshly shredded mozzarella: It generally melts more smoothly than pre-shredded cheese.
Don’t skip the Parmesan: Parmesan adds the salty, nutty flavor that makes the dish taste more like classic Chicken Parmesan.
Want a crispy coating? Traditional Chicken Parmesan is usually breaded and fried or baked. A slow cooker version won’t develop the same crispy crust. For a closer-to-restaurant-style result, coat the cooked chicken with breadcrumbs and Parmesan, add mozzarella, and briefly broil it until golden and bubbly.
❤️ Easy Busy-Night Version
If you’re really short on time, you can simplify the recipe to just chicken + marinara + Italian seasoning + mozzarella + Parmesan. Add everything to the slow cooker, cook until the chicken reaches 165°F/74°C, add the cheeses at the end, and serve over pasta.
