Tips for Perfect Cheesy Mozzarella Chicken
-
Avoid overcooking – Check at the lower end of the cooking range.
-
For thicker sauce – Remove chicken and whisk in a cornstarch slurry (1 tsp cornstarch + 2 tsp water) into the sauce; cook uncovered for 10 minutes.
-
For extra browning – After slow cooking, pop the chicken under the broiler for 2-3 minutes to get that golden cheese crust.
Storage
-
Fridge: Store leftovers in an airtight container for up to 3 days.
-
Freezer: Freeze in portions for up to 2 months; thaw in fridge overnight before reheating.
FAQ
Can I use frozen chicken?
Yes — but increase cooking time by about 1 hour on low.
Can I make this without cheese?
Technically yes, but you’d lose the “cheesy” magic. Try dairy-free mozzarella if needed.
Can I double the recipe?
Absolutely! Just make sure your slow cooker is large enough.
