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

Step 1: Preheat Oven
Begin by preheating your oven to 375°F (190°C). This ensures a perfectly baked finish for your Pasta Bake with Pumpkin Tomato Sauce. While the oven warms, gather your baking dish and prepare it by lightly greasing it with cooking spray or a touch of olive oil.

Step 2: Cook Pasta
In a large pot, bring salted water to a rolling boil. Add your choice of dry pasta, cooking it until it’s just 2 minutes shy of al dente, about 8-10 minutes. Once cooked, drain the pasta in a colander, reserving a cup of the pasta water for later. Set the pasta aside as you prepare the delicious sauce.

Step 3: Prepare Topping
In a skillet over medium heat, melt butter and add finely chopped walnuts and sage. Cook for about 5 minutes, stirring occasionally until the walnuts are nicely toasted and fragrant. This walnut-sage topping will add a delightful crunch to your pasta bake. Set it aside in a small bowl once done.

Step 4: Sauté Aromatics
Using the same skillet, add 2 tablespoons of olive oil and warm over medium heat. Add sliced mushrooms and chopped onion, cooking for 7-8 minutes until they are softened and the onions are translucent. The aroma will fill your kitchen, inviting everyone to gather for the upcoming meal.

Step 5: Build Flavor
Stir in the tomato paste, minced garlic, and crushed red pepper flakes to the skillet. Cook this mixture for about 2-3 minutes, allowing it to develop a rich, brick-red color. This step enhances the flavor profile of your Pasta Bake with Pumpkin Tomato Sauce, making it wonderfully savory.

Step 6: Add Spinach
Incorporate the fresh baby spinach into the skillet, stirring until it wilts—about 2-3 minutes. The vibrant green color will contrast beautifully with the rich sauce and add vital nutrients to your comforting dish. Make sure the spinach is well mixed among the other vegetables.

Step 7: Season and Combine
Mix in dried oregano, kosher salt, black pepper, and ground nutmeg to the skillet. Pour in the vegetable broth and pumpkin purée, stirring until the mixture is smooth and well combined. Allow it to simmer for a few minutes until heated through, creating a luscious sauce to coat the pasta.

Step 8: Combine Pasta
Add the reserved cooked pasta to the skillet, tossing gently to coat it in the creamy pumpkin tomato sauce. Ensure every piece of pasta is nestled in the sauce, soaking up all the delicious flavors. Now is the perfect time to taste and adjust the seasoning if needed.

Step 9: Transfer to Baking Dish
Carefully transfer the pasta mixture into your greased baking dish, spreading it out evenly. Top it with the remaining fontina cheese and the toasted walnut-sage mixture, making sure each bite will have that delightful topping. This ready-to-bake dish is sure to be a hit.

Step 10: Bake to Perfection
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 10-15 minutes. Look for that golden, bubbly cheese as your Pasta Bake with Pumpkin Tomato Sauce comes to life, smelling heavenly and inviting.

Storage Tips for Pasta Bake with Pumpkin Tomato Sauce

Fridge: Store any leftovers in an airtight container for up to 5 days. This helps keep the flavors fresh while avoiding unwanted moisture.

Freezer: You can freeze the pasta bake with pumpkin tomato sauce for up to 3 months. Make sure to wrap it tightly in plastic wrap and then in aluminum foil to prevent freezer burn.

Reheating: When ready to enjoy leftovers, thaw overnight in the fridge and reheat in the oven at 350°F (175°C) until warmed through, adding a splash of vegetable broth if it seems dry.

Room Temperature: It’s best to avoid leaving cooked pasta bakes out at room temperature for longer than 2 hours to ensure food safety and quality.

Expert Tips for Pasta Bake with Pumpkin Tomato Sauce

Pasta Perfection: Ensure your pasta is cooked al dente before mixing it with the sauce; this prevents it from becoming mushy during baking.
Creamy Consistency: If the sauce seems too thick, gradually stir in reserved pasta water or additional vegetable broth for the perfect creamy consistency in your pasta bake with pumpkin tomato sauce.
Flavor Boost: For an extra punch, consider adding a sprinkle of smoked paprika or a dash of balsamic vinegar when sautéing the vegetables—this enhances the dish’s complex flavors.
Mind the Topping: Don’t skip toasting the walnut and sage topping! This step adds a delightful crunch and flavorful contrast to the creamy base of your pasta bake.
Storage Savvy: If you have leftovers, store them in an airtight container; adding a splash of broth while reheating helps retain moisture and flavor.
Vegan Variation: To make this dish vegan-friendly, replace cheese with plant-based alternatives and use vegan butter for the topping!

Make Ahead Options

This Pasta Bake with Pumpkin Tomato Sauce is perfect for meal prep enthusiasts who want to enjoy a cozy fall dish without the last-minute rush! You can prepare the sauce (steps 4-7) up to 3 days in advance and store it in an airtight container in the fridge. Simply reheat it gently on the stove, adding a splash of vegetable broth if needed to maintain creaminess.
