2. Add to Crockpot: Place the seasoned chicken breasts at the bottom of the crockpot.
3. Pour Marinara Sauce: Spread the marinara sauce evenly over the chicken, ensuring they are entirely covered.
4. Set the Temperature: Cover the crockpot and set it to low for 4-6 hours or high for 2-3 hours.
5. Add Cheese: About 30 minutes before serving, sprinkle the mozzarella and Parmesan cheese on top of the chicken.
