When you need an easy weeknight win, this gluten-free pasta bake checks all the boxes. A cheesy spaghetti casserole is a family-favorite recipe packing in flavor with browned Italian sausage in a creamy tomato sauce and lots of gooey mozzarella. It requires only a handful of ingredients, simple prep, and guarantees no mushy baked pasta!
Preheat the oven to 400℉. Grease a 9X13 inch baking dish and set aside.
Start with boiling unsalted water for the pasta. Cook for 2 minutes less then al dente (8 minutes with Rummo spaghetti). Drain and rinse in cold water to stop the cooking; set aside in the colander.

Meanwhile while the pasta is cooking, heat a skillet over medium high heat. Add the olive oil and brown the sausage with onions and garlic until the sausage is no longer pink, about 6 minutes.
½ tablespoon olive oil, 1 pound bulk mild sweet Italian sausage, 1 small onion, 2 garlic cloves
Reduce the heat to medium low and add the marinara and cream cheese. Stir and heat until the cream cheese is smooth, about 5 minutes. Remove from the heat and stir in ½ cup mozzarella cheese.
In the empty pot the pasta was cooked in, combine the sauce with the cooked pasta. Transfer to the prepared baking dish and spread evenly. Top with remaining mozzarella cheese. Bake for 20 minutes, or until heated through and cheese is melted.
