Savory Mushroom and Spinach Spaghetti Casserole Recipe Walkthrough

First, let's get that oven preheating to 375°F. While it warms up, cook the spaghetti as the package directs. Once it's perfectly al dente, drain it and set it aside. Now, heat up a large skillet over medium heat, adding the olive oil. Toss in the mushrooms and give them a sauté until they're golden brown, which should take about 5 minutes.

Next, stir in the fresh spinach and continue cooking until it wilts down nicely. This shouldn't take long, just a couple of minutes. In a large mixing bowl, combine your cooked spaghetti with the sautéed mushrooms and spinach. Add in the marinara sauce, ricotta cheese, mozzarella, and Parmesan. Sprinkle in the garlic powder, oregano, and a pinch of salt and pepper. Mix everything until well combined.

Transfer this delicious mixture into a greased casserole dish, spreading it out evenly. Pop it into your preheated oven and let it bake for about 25 minutes. You'll know it's done when the cheese is bubbling and golden brown on top. Once out of the oven, let it cool for a quick 5 minutes before serving. Enjoy!
