Ingredients and Substitutes

Chicken breasts (4 breasts) –This recipe uses boneless and skinless breasts.

Garlic powder (1 tsp) – You can also use minced garlic here for an even more aromatic bake. But garlic powder is a very convenient spice that will do the job well.

Onion powder (1 tsp) – To add a more flavorful touch, use the powder.

Italian seasoning (1 tsp) – You cannot have a mozzarella and tomato bake without having some Italian flavors. Make sure to use Italian seasoning, but basil and oregano can do just as well.

Salt & black pepper (to taste)

Olive oil (2 tbsp)

Chopped tomatoes (16oz) – The recipe calls for canned chopped tomatoes, but feel free to use fresh ones if you have.

Garlic (3 cloves) –Garlic powder will not be as efficient here, but you can substitute with it, if you’ve run out of cloves.

Red onion (1/2 onion) – We use red onions for a more kicking flavor, but the yellow kind will also work.

Oregano (1 tsp) – Fresh or dried leaves will both work here.

Mozzarella (1 cup) – Shredded mozzarella cheese is best here, so I wouldn’t suggest using an alternative.

Basil (2-3 leaves) – Just like the oregano, fresh basil works best, but you can totally use dried leaves.

How to Make Chicken Mozzarella Bake

Step 1. Start by preheating your oven to 375 degrees F. Wash your chicken and pat dry with paper towels.

Then, cut with a knife in squares but not all the way through, as seen in picture 1 below. Make sure not to cut all the way through.

Step 2. Place the cut chicken breast into a baking dish. Add your spices there – salt, pepper, Italian seasonings, onion and garlic powder. And drizzle with the olive oil.

Step 3. Grab a mixing bowl and add the sauce ingredients there. Chopped tomatoes, garlic, chopped red onion, oregano, salt and black pepper.

Step 4. Make sure to combine all of the sauce ingredients well so it is well incorporated.

Step 5. Pour the tomato mixture over the chicken breast.

Step 6. Then, sprinkle the grated mozzarella cheese over.

Step 7. Place the dish in the oven and bake for 25 to 30 minutes. Make sure to put it under the broiler for about 4 minutes at the end.

What to Serve with Mozzarella Chicken

My absolutely favorite thing to serve with mozzarella chicken is garlic bread and a fresh, green salad. Of course, and a glass of cold, dry, white wine, too!

But anything that usually goes well with lighter meat dishes will do fine here, too.

You can serve potatoes, rice, or even pasta. Heck, pasta salad, too! As long as it provides comfort and satisfies your taste buds, the side dish is well-approved!
