Easy Baked Chicken Parmesan (No Breading)

Ingredients
6 boneless skinless chicken breasts…
1 (16 ounce) bottle light Italian dressing
1⁄2 cup light ranch salad dressing
2 tablespoons olive oil
5 tablespoons minced garlic, divided (I used the pre-minced stuff from the jar)
2 1⁄4 cups shredded parmesan cheese, divided (not the stuff in the green jar)
1 tablespoon dried parsley
olive oil flavored cooking spray
1⁄3 cup finely chopped white onion (mild in flavor)
1 (8 ounce) can tomato sauce
1 (6 ounce) can tomato paste
3 tablespoons dried basil, divided
3 tablespoons dried oregano, divided
1⁄2 teaspoon salt
1⁄2 teaspoon black pepper
1 bay leaf
1 1⁄2 cups 2% mozzarella cheese, grated
Directions
The morning or the night before serving, combine italian dressing, ranch dressing, 3 tablespoons minced garlic and 2 tablespoons olive oil in a large zip lock bag. Squish bag around to combine all ingredients. Add chicken breasts to bag, close and squish until they are well coated in the dressing mixture. Put the bag in bowl (to prevent spills) and refrigerate all day or overnight up 24 hours.
When ready to cook, Preheat oven to 400*F. Then mix 2 cups parmesan cheese, with parsley, 1 1/2 tablespoons of the basil and oregano (each).
Spray a large baking dish (big enough for all six breasts) with olive oil cooking spray.
Remove chicken from baggie one by one and “dredge” in the cheese and spice mixture, until thoroughly coated in cheese mixture. Then place chicken in a single layer in the dish.
When all chicken is coated, place chicken in oven and bake for 20-25 minutes (or until the internal temp is 155*F).
While chicken bakes, in a large non stick sauce pan, make the sauce.
Spray sauce pan with olive oil cooking spray (or use 1 tablespoon olive oil but do not use another flavor spray). Then saute onions and remaining garlic until tender and onions are translucent.
Add tomato paste and tomato sauce to garlic and onions. Stir until smooth. Then add the remaining, oregano and basil and the other spices including the bay leaf. (At this point if sauce looks to thick for your liking add 1 tomato sauce can of water) Allow to simmer for the remainder of the baking time until you need it.
When chicken has baked 20 minutes, remove from oven and top each breast with sauce (to your liking, we cover the whole thing) then top with 1/4 cup of mozarella cheese (again to your liking) put baking dish back into the oven for 10 more minutes or until cheese is bubbly. Then switch your broiler on to brown cheese (optional).
Remove from oven and sprinkle with remaining parmesan cheese.
Serve it up, I have never had anyone not finish this!
