This Mushroom Cauliflower Alfredo Pasta Bake offers a creamy, comforting twist on classic pasta dishes by using a rich cauliflower-based Alfredo sauce.
Make the cauliflower alfredo sauce according to your preferred recipe or instructions, ensuring it has a creamy texture suitable for mixing into the pasta.
Heat 1 tablespoon of olive oil in a skillet over medium heat. Add the sliced mushrooms and diced onion, cooking for 10-15 minutes until the mushrooms release their liquid and both vegetables soften and caramelize.
Boil the penne pasta in salted water until al dente, following package instructions. Drain and set aside.
In a large 13 x 9-inch baking dish, mix together the cooked penne, sautéed mushrooms and onions, freshly grated parmesan cheese, chopped parsley, and the prepared cauliflower alfredo sauce. Stir well to evenly coat the pasta with the sauce.
Add 1 teaspoon of salt or adjust to taste, mixing thoroughly.
Sprinkle the cup of mozzarella evenly over the top of the pasta mixture in the baking dish.
Preheat the oven to 400°F (200°C). Bake the casserole for 10-15 minutes, or until the cheese on top is bubbly and begins to brown.
Remove from oven and allow to cool slightly before serving. Garnish with additional fresh parsley if desired.
