Step‑by‑Step Instructions for Pasta Bake with Pumpkin Tomato Sauce

Step 1: Preheat the Oven
Begin by preheating your oven to 375°F (190°C) to ensure it’s hot and ready for baking. While the oven heats up, gather all your necessary ingredients and equipment, including a large pot, a sauté pan, and a baking dish. This preparation will streamline the cooking process and help you make this delicious Pasta Bake with Pumpkin Tomato Sauce efficiently.

Step 2: Cook the Pasta
In a large pot, bring salted water to a boil and add your chosen pasta. Cook until the pasta is just 2 minutes short of al dente, typically around 6–8 minutes, depending on the type. Once done, drain the pasta and set it aside temporarily in a colander, allowing the steam to escape while you prepare the delicious sauce.

Step 3: Prepare the Walnut-Sage Topping
In the same sauté pan, melt 2 tablespoons of unsalted butter over medium heat. Add the finely chopped walnuts and 1 tablespoon of fresh sage, cooking for about 5 minutes until the walnuts are golden and fragrant. Once toasted, remove them from the pan and set aside, allowing the flavors to deepen while you focus on the sauce.

Step 4: Sauté the Vegetables
Using the same sauté pan, heat 2 tablespoons of extra-virgin olive oil over medium heat. Add the sliced cremini mushrooms and the finely chopped yellow onion, sautéing for about 8 minutes until the onions are translucent and the mushrooms have softened. Stir occasionally to ensure even cooking and prevent sticking, creating a rich flavor base for your Pasta Bake with Pumpkin Tomato Sauce.

Step 5: Create the Sauce
Next, stir in 1/4 cup of tomato paste, minced garlic, and 1/2 teaspoon of crushed red pepper flakes into the sautéed vegetables. Cook for 3–4 minutes, allowing the mixture to caramelize and develop a deep flavor. The aroma should be mouthwatering, filled with savory goodness, preparing your taste buds for the creamy sauce that follows.

Step 6: Add the Greens and Seasonings
Gradually add about 3–4 handfuls of fresh baby spinach to the pan, stirring until the greens have wilted down completely, about 2–3 minutes. Season the mixture with 1 teaspoon oregano, 1 teaspoon kosher salt, 1/2 teaspoon black pepper, and 1/4 teaspoon ground nutmeg. Mix well, ensuring every ingredient is evenly coated in the fragrant spices.

Step 7: Combine the Broth and Pumpkin
Pour in 3 cups of vegetable broth to deglaze the pan, scraping up any browned bits from the bottom for extra flavor. Mix in one 15-ounce can of pumpkin purée along with 1/2 cup of grated Parmesan cheese and half of the 1 1/2 cups of grated Fontina cheese. Stir until the sauce is smooth and creamy, ready to envelop your pasta.

Step 8: Mix Pasta and Sauce
In a large mixing bowl, combine the cooked pasta with the creamy pumpkin tomato sauce. Stir gently but thoroughly, ensuring every piece of pasta is well coated in the rich mixture. This step is crucial as it allows the flavors to meld beautifully within the Pasta Bake with Pumpkin Tomato Sauce, creating a comforting dish.

Step 9: Prepare for Baking
Transfer the pasta and sauce mixture into a greased baking dish, spreading it out evenly. Top with the remaining Fontina cheese and the walnut-sage mixture you prepared earlier, ensuring a delightful crunch and cheesy top layer. This adds a tasty contrast to the creamy pasta below while enhancing the overall flavor.

Step 10: Bake the Dish
Cover the baking dish with foil and place it in the preheated oven. Bake for 15 minutes, then carefully remove the foil and bake for an additional 10 minutes. Keep an eye on it, and look for a golden, bubbly surface as the cheese melts into perfection, revealing an invitingly rich Pasta Bake with Pumpkin Tomato Sauce ready to be served.

When you’re ready to enjoy the dish, just combine the prepared pasta and sauce in a baking dish, top with cheese and walnuts, and bake for about 25 minutes at 375°F.
