Step-by-Step Instructions
Step 1: Season the Chicken
Pat the chicken breasts dry using paper towels.
Season both sides with:
- Garlic powder
- Italian seasoning
- Onion powder
- Salt
- Black pepper
This simple seasoning blend creates a flavorful base.
Step 2: Arrange in the Slow Cooker
Lightly grease the slow cooker if desired.
Place the chicken breasts in a single layer.
Pour the marinara sauce evenly over the chicken, making sure every piece is coated.
Step 3: Slow Cook
Cover with the lid.
Cook on:
- Low: 4–6 hours
- High: 2–3 hours
The chicken is done when it reaches an internal temperature of 165°F (74°C) and is tender enough to cut easily with a fork.
Avoid overcooking, as chicken breasts can become dry if left in the slow cooker for too long.
Step 4: Add the Cheese
Sprinkle the mozzarella evenly over the chicken.
Top with grated Parmesan cheese.
Replace the lid and cook for another 10–15 minutes, just until the cheese is fully melted.
Step 5: Garnish and Serve
Sprinkle chopped parsley or fresh basil over the top for extra freshness.
Serve immediately while the cheese is hot and bubbly.

Frequently Asked Questions
Can I use chicken thighs?
Yes. Boneless, skinless chicken thighs work well and tend to stay even juicier during slow cooking.
Can I use frozen chicken?
For food safety, it’s generally recommended to thaw chicken completely before placing it in a slow cooker. Starting with frozen chicken may keep it in the temperature “danger zone” for too long.
Is this recipe gluten-free?
It can be, provided you use a certified gluten-free marinara sauce and ensure all other ingredients are gluten-free.
Can I make it ahead of time?
Yes. You can season the chicken and refrigerate it overnight. Add it to the slow cooker with the sauce the next day for an easy meal.
