Why You’ll Love This Pumpkin Pasta Bake

Whether you’re a busy mom juggling school pickups and Zoom calls or just someone who wants to add more plant-based meals to their rotation, this Pumpkin Pasta Bake is here to rescue dinner time. It’s rich, savory, and perfectly creamy thanks to a dreamy blend of pumpkin purée and tomato paste. Plus, it sneaks in veggies like spinach and mushrooms without raising red flags for picky eaters.

Ingredients You’ll Need:

1 lb dry pasta (rigatoni, ziti, fusilli, or your fave shape)
2 Tbsp butter
½ cup chopped walnuts
1 Tbsp + 2 tsp chopped fresh sage
2 Tbsp olive oil
8 oz cremini mushrooms, sliced
1 yellow onion, chopped
¼ cup tomato paste
4 garlic cloves, minced
½ tsp crushed red pepper flakes
3-4 handfuls baby spinach
1 tsp dried oregano
1 tsp kosher salt
½ tsp black pepper
¼ tsp nutmeg
3 cups vegetable broth
1 can (15 oz) pumpkin purée
½ cup grated Parmesan
1 ½ cups grated fontina

How to Make It:

Preheat oven to 375ºF. Cook pasta until 2 minutes before al dente, then drain.
In a large skillet, melt butter over medium. Add walnuts and 1 Tbsp sage; toast for 5 minutes. Season with a pinch of salt and set aside.
In the same pan, heat olive oil. Add mushrooms and onion; sauté 8 minutes.
Stir in tomato paste, garlic, and red pepper flakes. Cook 3-4 minutes until the paste deepens in colour.
Add spinach a handful at a time until wilted. Mix in oregano, remaining sage, salt, pepper, and nutmeg.
Pour in broth, scraping the bottom of the pan. Add pumpkin, Parmesan, and ½ cup fontina. Stir until smooth.
Mix the sauce with the cooked pasta. Transfer to a greased 13×9″ baking dish.
Top with remaining fontina and the walnut-sage mix. Cover with foil and bake 15 minutes.
Remove foil and bake 10 more minutes until bubbly and golden.

Tips to Make This a Weeknight Win

Swap fontina with mozzarella or gruyère if that’s what you have.
Use canned mushrooms to save time (but fresh is best for flavor!).
Make it ahead: Prep up to step 7, refrigerate, then bake when ready.
Gluten-free pasta works great here, too—just watch the cook time.

Why This One’s Close to My Heart

I first whipped this up one brisk October evening when my pantry was down to odds and ends. A can of pumpkin, leftover pasta, and a dream. I crossed my fingers and hoped for the best. Not only did my family devour it—even my spinach-averse youngest—but it quickly became our cozy season tradition. Now, the smell of sage and bubbling cheese feels like a hug from the kitchen.

What to Serve With It

Pair your Pumpkin Pasta Bake with a simple arugula salad tossed in balsamic vinaigrette for brightness. Add some crusty bread for mopping up the extra sauce (you won’t want to waste a drop). And if you’re feeling festive, a crisp apple cider—sparkling or hard—is the perfect fall touch.

How to Store Leftovers

Cool completely before storing. Keep leftovers in an airtight container in the fridge for up to 4 days. Reheat in the oven at 350ºF, covered, for 20 minutes. Or microwave single servings for 2-3 minutes. You can also freeze portions for up to 2 months—just thaw overnight in the fridge before reheating.

Is this really a good vegetarian dinner?

Yes! It’s protein-rich with walnuts, cheese, and veggies. Meat lovers won’t even miss it.

Can I make this with gluten-free pasta?

Definitely. Just adjust your cook time so it doesn’t turn mushy when baked.

What’s the best pasta shape for a baked pasta?

Rigatoni, ziti, or shells hold the sauce well. But really, use what you love.
