Pasta Bake with Pumpkin Tomato Sauce Ingredients

For the Pasta
• Dry Pasta (1 lb) – This forms the essential base of your baked dish; any tubular pasta works well.

For the Sauce
• Unsalted Butter (2 Tbsp) – Adds a rich depth of flavor; swap with olive oil for a dairy-free version.
• Cremini Mushrooms (8 oz, sliced) – Contributes umami and a hearty texture; button mushrooms are a fine substitute.
• Yellow Onion (1, finely chopped) – Enhances sweetness and overall depth; shallots can be used instead.
• Garlic (4 cloves, minced) – Imparts aromatic flavor to the sauce; fresh garlic powder serves as a quick alternative.
• Tomato Paste (1/4 cup) – Intensifies the tomato flavor; an essential component for your sauce.
• Crushed Red Pepper Flakes (1/2 tsp) – Provides a hint of heat; skip this if you’re aiming for a milder taste.
• Fresh Baby Spinach (3 to 4 handfuls) – Brings in nutrients and vibrant color; kale or Swiss chard can be swapped in.
• Dried Oregano (1 tsp) – Elevates the flavor profile, with basil as a tasty alternative.
• Ground Nutmeg (1/4 tsp) – Adds warmth that complements the pumpkin beautifully; omit if sensitive to spices.
• Vegetable Broth (3 cups) – Used for deglazing and enhancing flavors in your sauce; chicken broth is fine if not vegetarian.
• Pumpkin Purée (1 (15-oz.) can) – The heart of the sauce providing both creaminess and flavor; essential for a Pasta Bake with Pumpkin Tomato Sauce.

For the Topping
• Walnuts (1/2 cup, finely chopped) – Adds a delightful crunch and nuttiness; pecans or sunflower seeds can step in for variety.
• Fresh Sage (1 Tbsp + 2 tsp, finely chopped) – Infuses warm herbal notes; thyme or oregano also work well.
• Grated Parmesan Cheese (1/2 cup) – Contributes a salty, nutty zing; use pecorino or nutritional yeast for a vegan option.
• Grated Fontina Cheese (1 1/2 cups, divided) – Melts beautifully, providing a creamy texture; Gruyère is a great substitute.

Enjoy your cooking journey with this enchanting blend of flavors and make your kitchen come alive with the essence of autumn!

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

Step 1: Preheat Oven
Begin your delicious journey by preheating your oven to 375ºF (190ºC). This ensures the oven is hot and ready to embrace your heavenly Pasta Bake with Pumpkin Tomato Sauce once assembled, giving it that lovely golden finish for the perfect bake.

Step 2: Cook Pasta
Bring a large pot of salted water to a rolling boil. Add in your dry pasta and cook for 2 minutes less than the package instructions suggest—just shy of al dente. Drain the pasta and set it aside in a large bowl, ready to soak up all those glorious flavors in your sauce.

Step 3: Prepare Walnut-Sage Mixture
In a large skillet over medium heat, melt the unsalted butter. Once melted, toss in the finely chopped walnuts and sage, stirring them for about 5 minutes until they’re lightly toasted and fragrant. Season the mixture with a touch of salt before transferring it to a bowl—this crunchy topping will bring wonderful texture to your pasta bake!

Step 4: Sauté Vegetables
In the same skillet, add 2 tablespoons of extra-virgin olive oil over medium heat. Gently sauté the sliced cremini mushrooms and chopped yellow onion for about 8 minutes until they are soft and golden. This step builds a delightful base of flavor before we start layering in the sauce for our Pasta Bake with Pumpkin Tomato Sauce.

Step 5: Build Sauce
Stir in the tomato paste, minced garlic, and crushed red pepper flakes into your sautéed vegetables. Cook for 3-4 minutes until the tomato paste caramelizes slightly, providing depth to the sauce. Gradually add the baby spinach in batches, allowing it to wilt down before proceeding to the next step—this ensures a vibrant, nutrient-rich mixture.

Step 6: Season and Combine
Now, stir in the dried oregano, kosher salt, black pepper, and ground nutmeg into your spinach mix. Pour in the vegetable broth and deglaze the skillet, scraping any tasty bits from the bottom. Once well combined, add the pumpkin purée and half of the grated fontina, stirring until the mixture is smooth and inviting, ready to envelop your pasta.

Step 7: Mix in Pasta
Add your cooked pasta to the creamy pumpkin tomato sauce in the skillet. Gently fold the pasta into the sauce, ensuring every piece is thoroughly coated and the sauce has embraced the pasta beautifully. This mixture is what will make your Pasta Bake with Pumpkin Tomato Sauce so comforting and delicious!

Step 8: Transfer to Baking Dish
Carefully pour the pasta mixture into a greased 13×9-inch baking dish. Evenly distribute the remaining grated fontina cheese on top, followed by the toasted walnut-sage mixture. This layer will create a lovely crispy topping that enhances each bite of your savory baked dish.

Step 9: Bake
Cover the baking dish with foil and place it in the preheated oven. Bake for 15 minutes, then remove the foil and continue baking for another 10 minutes. Keep an eye on it—the cheese should turn beautifully golden, creating a mouthwatering crust that signifies your delectable Pasta Bake with Pumpkin Tomato Sauce is ready to be enjoyed.

Pasta Bake with Pumpkin Tomato Sauce Recipe FAQs

How do I choose ripe pumpkins for this dish?
Absolutely! When selecting a pumpkin, look for one that feels heavy for its size, with a firm skin that’s free of blemishes or soft spots. A pumpkin with a rich, vibrant color is often a good sign of ripeness. If using canned pumpkin purée, make sure it’s 100% pumpkin without additives for the best flavor in your pasta bake.

What’s the best way to store leftovers of this pasta bake?
Very good question! Store leftovers in an airtight container in the refrigerator for up to 5 days. Ensure it’s completely cooled before sealing to prevent moisture accumulation. If you’d like to enjoy it longer, consider freezing it—just cool it down and place it in freezer-safe containers for up to 3 months. Always label your containers—this can make meal prep feel organized and exciting!

Can I freeze the Cheesy Pumpkin Pasta Bake after baking?
Absolutely! To freeze, first let the dish cool completely after baking. Then, slice it into portions or leave it whole, and transfer it to freezer-safe containers or heavy-duty freezer bags. Make sure to label the bags with the date. Thaw overnight in the refrigerator when you’re ready to enjoy it again, and reheat in the microwave or oven with a splash of vegetable broth to rejuvenate its creamy texture.

What if my pasta bake is too dry after baking?
Not to worry! If your pasta bake seems a bit dry, it could be due to the pasta soaking up too much moisture. Next time, try cooking the pasta just shy of al dente, and be sure to add enough liquid when assembling. If it still happens, you can add a splash of broth or cream before serving to bring it back to its creamy glory!

Are there any allergens in the ingredients I should consider?
Certainly! This recipe contains ingredients like walnuts and cheese, both of which can trigger allergies. If you’re serving guests, be sure to check their dietary restrictions.
