This One Pot Cheesy Pumpkin Pecan Pasta is fall comfort food at its finest — creamy, cheesy pasta swirled with silky pumpkin sauce and finished with crunchy toasted pecans for the perfect textural contrast. Best of all, it all comes together in a single pot, meaning less cleanup and more time to enjoy dinner. It’s cozy, a little unexpected, and ready in about 30 minutes.
Ingredients You’ll Need
- 12 oz short pasta (penne, rigatoni, or shells)
- 2 tablespoons butter
- 1 small yellow onion, diced
- 3 cloves garlic, minced
- 1 cup pumpkin puree (not pumpkin pie filling)
- 2 1/2 cups vegetable or chicken broth
- 1 cup whole milk or half-and-half
- 1/2 teaspoon dried sage
- 1/4 teaspoon nutmeg
- 1/2 teaspoon salt, plus more to taste
- 1/4 teaspoon black pepper
- 1 1/2 cups shredded sharp cheddar cheese
- 1/2 cup grated Parmesan cheese
- 2/3 cup pecans, roughly chopped and toasted
- Fresh sage or parsley, for garnish, optional
How to Make (Step-by-Step)
1. Sauté the aromatics. Melt the butter in a large pot or deep skillet over medium heat. Add the diced onion and cook for 3–4 minutes, until softened. Stir in the garlic and cook for 30 seconds more, until fragrant.
2. Build the sauce base. Stir in the pumpkin puree, broth, milk, dried sage, nutmeg, salt, and pepper. Bring the mixture to a gentle simmer.
3. Add the pasta. Stir in the dry pasta, making sure it’s mostly submerged in the liquid. Cover and simmer for 12–15 minutes, stirring occasionally, until the pasta is tender and most of the liquid has absorbed.
4. Melt in the cheese. Reduce the heat to low. Add the cheddar and Parmesan in handfuls, stirring until the cheese fully melts and the sauce turns smooth and creamy.
5. Toast the pecans. While the pasta simmers, toast the chopped pecans in a dry skillet over medium heat for 3–4 minutes, stirring frequently, until fragrant and lightly browned. Set aside.
6. Finish and serve. Taste the pasta and adjust salt and pepper as needed. Divide into bowls, top with toasted pecans, and garnish with fresh sage or parsley if desired. Serve immediately while warm and creamy.
Recipe Tips
- Toast the pecans separately. Toasting brings out their natural oils and flavor, making a noticeable difference compared to adding them raw.
- Adjust the sauce consistency. If the pasta looks too thick after the cheese melts, stir in a splash of extra broth or milk to loosen it up.
- Use freshly grated cheese. Pre-shredded cheese contains anti-caking agents that can make the sauce grainy — grating your own cheddar and Parmesan gives the smoothest results.
- Balance the sweetness. A small pinch of cayenne or red pepper flakes cuts through the natural sweetness of the pumpkin nicely.
- Stir often while simmering. Since this is a one-pot pasta, stirring occasionally prevents the pasta from sticking to the bottom of the pot.
Storage & FAQ
How to Store
Store leftovers in an airtight container in the refrigerator for up to 4 days. The sauce will thicken as it chills, so reheat gently on the stovetop or in the microwave with a splash of milk or broth to loosen it back up.
How to Freeze
This pasta can be frozen, though the creamy sauce may separate slightly upon thawing. To freeze, cool completely and store in a freezer-safe container for up to 2 months. Thaw overnight in the refrigerator, then reheat slowly on the stovetop over low heat, stirring in a little extra milk or broth to bring the sauce back together. For best texture, add the toasted pecans fresh after reheating rather than freezing them with the pasta.
FAQ
Can I use fresh pumpkin instead of canned?
Yes — roast and puree fresh pumpkin until smooth, making sure it’s well-drained so it doesn’t add excess water to the sauce.
Can I make this vegetarian?
Yes, simply use vegetable broth in place of chicken broth; the rest of the recipe is already vegetarian-friendly.
What can I use instead of pecans?
Walnuts or toasted pumpkin seeds (pepitas) make great substitutes if you don’t have pecans on hand.
Can I add protein to this dish?
Cooked, shredded rotisserie chicken or crispy pancetta stirred in at the end pairs wonderfully with the creamy pumpkin sauce.
Why did my sauce turn grainy?
This usually happens when the cheese is added over too-high heat or all at once. Lower the heat and add cheese gradually, stirring continuously for a smooth sauce.
