• Salt and pepper to taste

Directions:

1. Preheat and Prepare: Preheat oven to 375°F. Grease a 9x13-inch baking dish with olive oil or non-stick spray to prevent sticking.
2. Cook the Pasta: In a large pot of salted boiling water, cook penne pasta according to package instructions until al dente. Drain and set aside.

5. Season and Simmer: Mix in oregano, basil, and red pepper flakes if using. Season with salt and pepper to taste. Pour in marinara sauce and let simmer for 5 minutes to blend flavors.
6. Combine with Pasta and Cheese: In a large mixing bowl, combine cooked pasta with the mushroom-sauce mixture. Stir in ricotta cheese until evenly distributed.
7. Layer the Casserole: Spread half the pasta mixture in the prepared baking dish. Sprinkle with half the mozzarella and Parmesan. Repeat with remaining pasta, then top with the rest of the cheeses.
8. Bake Covered, Then Uncovered: Cover with foil and bake for 20 minutes. Remove foil and bake for another 10 minutes, until cheese is bubbly and golden.
