• Butter: Gives a layer of richness right from the start, especially when toasting those walnuts and sage.
• Walnuts: Add crunch and earthiness, plus they soak up that browned butter flavor beautifully.

• Garlic: Four cloves may sound like a lot, but it gives beautiful, subtle depth.
• Crushed Red Pepper Flakes: Just a bit for gentle heat and complexity.
• Fresh Baby Spinach: Adds freshness and vibrant green, not to mention extra nutrients.

• Kosher Salt & Black Pepper: Don’t skimp! Proper seasoning is key to making this dish sing.
• Ground Nutmeg: Just a pinch lifts the sauce and complements the pumpkin’s sweetness.
• Vegetable Broth: Thins the sauce so it’s luxurious but not heavy, and binds flavors together.
• Pumpkin Purée: The magic ingredient—it makes the sauce creamy, autumnal, and so unique.

• Fontina Cheese: For all the cheesy stretch and nutty flavor that makes a baked pasta irresistible.

How to Make Pasta Bake with Pumpkin Tomato Sauce

Step 1: Cook the Pasta

Start by getting a big pot of salted water boiling. You want it to taste like the ocean—this gives your pasta the best base flavor. Add your chosen pasta and cook until just shy of al dente, about two minutes less than the package says. The pasta will finish cooking in the oven and soak up all those wonderful flavors later. Drain well and set aside.

Step 2: Toast the Walnuts and Sage in Butter

In your largest sauté pan, melt the butter over medium heat. Add the walnuts and the first tablespoon of chopped fresh sage. Toast them together for about five minutes, stirring often. This combo fills your kitchen with the most comforting aroma. When the walnuts are golden and everything smells nutty and fragrant, sprinkle with a tiny pinch of salt and scoop the mixture into a small bowl for topping the bake later.

Step 3: Sauté the Vegetables

Return the pan to medium heat and swirl in the olive oil. Add your mushrooms and onion, and cook for about eight minutes, stirring occasionally. You want the onions to turn soft and the mushrooms to release their liquid and start to brown. This is where so much of the pasta’s savory backbone develops.

Step 4: Build the Pumpkin Tomato Sauce

Stir in the tomato paste, minced garlic, and red pepper flakes. Let this cook for three to four minutes, stirring constantly. You’ll see the tomato paste darken into a deep, brick red and start to caramelize—this takes the flavor over the top. Gradually add the spinach, stirring until it wilts. Then sprinkle in the oregano, salt, black pepper, nutmeg, and the remaining sage. Breathe in—it’s amazing!

Step 5: Make it Creamy

Pour in the vegetable broth, scraping up any tasty browned bits from the bottom of the pan. Stir in the pumpkin purée, Parmesan cheese, and half a cup of fontina cheese. Keep stirring until the cheese is melted and the sauce is velvety smooth and orange—a signature of this Pasta Bake with Pumpkin Tomato Sauce. If you dip in a spoon for a taste, you’ll know you’re on the right track.

Step 6: Combine Pasta and Sauce

Add your drained pasta to the pan and toss everything together. Be sure every noodle is generously coated in the luscious pumpkin-tomato sauce. This step is where the magic happens and you might want to sneak a taste — just to check the seasoning!

Step 7: Assemble and Bake

Transfer the saucy pasta mixture into a well-greased 13×9-inch baking dish. Sprinkle the remaining fontina cheese all over the top, and finish with the browned butter walnut-sage mixture you set aside earlier. Cover the dish with foil and bake at 375°F for 15 minutes, then remove the foil and bake for 10 minutes more. The cheese will be melty and golden, and the edges deliciously crisp. Let it rest for a few minutes before serving—all the flavors meld together as it cools slightly.

How to Serve Pasta Bake with Pumpkin Tomato Sauce

Garnishes

Pile your servings high and finish with a blizzard of extra grated Parmesan, a few small sage leaves, and maybe even a drizzle of good olive oil. The crunchy walnut-sage topping already adds a burst of texture, but a sprinkle of red pepper flakes or a crack of black pepper never hurts for those who love a bit more pizzazz.

Side Dishes

This Pasta Bake with Pumpkin Tomato Sauce is hearty enough on its own, but shines beautifully when paired with a fresh, zippy salad—something with arugula, lemon, and maybe shaved fennel for crunch. A simple garlic bread or warm, rustic loaf is also a complete crowd-pleaser, perfect for scooping up any extra sauce left on your plate.

Creative Ways to Present

For a dinner party, spoon the bake into individual ramekins for a personal touch—everyone gets their own bubbling mini casserole. Or, try serving it family-style in a gorgeous baking dish, straight from oven to table. For extra cozy vibes, scatter roasted pumpkin cubes or caramelized shallots over the top before baking.

Make Ahead and Storage

Storing Leftovers

Store any leftovers of your Pasta Bake with Pumpkin Tomato Sauce in an airtight container in the refrigerator. The flavors actually continue to deepen as it sits! It will keep beautifully for up to five days, making it great for meal prep or next-day lunches.

Freezing

This dish is a freezer superstar. Let your pasta bake cool completely, then transfer to a freezer-safe container or a zip-top bag (press out any air). It’ll keep for up to three months. When you’re ready for some comfort, simply thaw overnight in the fridge before reheating.

Reheating

For best results, reheat single servings in the microwave with a splash of broth, which keeps the pasta from drying out. To heat larger portions, cover the baking dish loosely with foil and warm in a 350°F oven until bubbly and heated through. The cheese will get melty again and your kitchen will smell heavenly, just like the first time.

FAQs

Can I use a different type of cheese?

Absolutely! While fontina melts beautifully, feel free to substitute mozzarella, sharp cheddar, or gouda for different flavor notes. A touch of Gruyère or provolone also works marvelously for extra richness.

Is Pasta Bake with Pumpkin Tomato Sauce suitable for vegans?

Yes, with simple swaps! Use a plant-based butter, your favorite vegan cheeses, and check that your pasta is egg-free. The pumpkin-tomato sauce itself is already dairy-free before the cheese is added, so it adapts easily.

Can I add protein to this pasta bake?

Of course! For extra heartiness, stir in cooked Italian sausage (for non-vegetarians), roasted chickpeas, white beans, or even sautéed tempeh before baking. The sauce is flavorful enough to complement any of these additions.

What can I use if I don’t have fresh sage?

No fresh sage? No problem. You can swap in half the amount of dried sage or use other herbs like thyme or rosemary. Each will bring a slightly different aromatic character, but all will taste delicious.

Is there a gluten-free version of this recipe?

Yes! Simply use your favorite gluten-free pasta. Everything else in the Pasta Bake with Pumpkin Tomato Sauce is naturally gluten-free, so you don’t need to make any other changes.
