Instructions

Cook the Spaghetti

Begin by boiling a large pot of salted water and cook the spaghetti according to package instructions until al dente. Reserving 1/2 cup of pasta water before draining is key to later adjusting the sauce consistency, ensuring it clings perfectly to the noodles.

Cook Bacon Until Crispy

In a large skillet over medium heat, cook the thick-cut bacon slices until golden and crisp. This renders flavorful fat and creates a crunchy topping. Transfer the bacon to paper towels to cool, then crumble it for easy mixing and garnishing.

Sauté Mushrooms in Bacon Fat

Drain most of the bacon grease, leaving about a tablespoon for sautéing. If needed, add olive oil to prevent sticking. Add the sliced mushrooms and cook for 5–7 minutes until browned and tender, enhancing their natural umami and developing deeper flavor.

Add Garlic and Spices

Stir minced garlic into the mushrooms and cook for about one minute until fragrant, avoiding burning. Then mix in pumpkin puree, dried thyme, smoked paprika, nutmeg, salt, and pepper. This spice blend enriches the pumpkin sauce with warmth and complexity.

Create the Creamy Pumpkin Sauce

Pour in the heavy cream and sprinkle the grated Parmesan cheese into the skillet. Simmer gently for 2–3 minutes, stirring frequently until the sauce thickens and becomes luxuriously creamy, ready to coat the pasta.

Toss Pasta with Sauce and Finish

Add the drained spaghetti to the sauce and toss thoroughly to combine. Use the reserved pasta water to loosen the sauce if it feels too thick, achieving a smooth, clingy texture that envelops every strand.

Serve with Crispy Bacon and Fresh Parsley

Plate the pasta and garnish generously with crumbled crispy bacon and chopped fresh parsley. Add extra Parmesan if desired. This final touch balances texture and adds brightness to the rich dish.

You Must Know

  • To make this dish vegetarian, omit the bacon and add toasted nuts or crispy shallots for crunch.
  • Dairy-free cream and cheese alternatives can be used for a plant-based version without compromising creaminess.
  • The pumpkin sauce can be prepared ahead and stored separately, making weeknight dinner prep even easier.

Storage Tips

Store leftover pumpkin pasta in an airtight container in the refrigerator for up to 3 days. Reheat gently on the stovetop with a splash of cream or reserved pasta water to restore creaminess.

Serving Suggestions

This dish pairs wonderfully with a crisp green salad or roasted autumn vegetables for a well-rounded meal. A glass of light white wine or sparkling water with lemon complements the flavors beautifully.

Professional Tips

  • Use canned pumpkin puree labeled for baking or cooking for the best texture and flavor.
  • Cook bacon slowly over medium heat to render fat fully and avoid burning, ensuring crispiness.
  • Adjust seasoning at the end, as Parmesan adds saltiness; taste before adding more.

FAQs

Can I use fresh pumpkin instead of canned?

Yes, but fresh pumpkin requires cooking and pureeing first. Use a sweet variety like sugar pumpkin, roast until tender, then puree for best results.

What type of mushrooms work best?

Cremini or baby bella mushrooms are ideal due to their robust flavor and meaty texture, but white button mushrooms are also fine.

How can I make this recipe vegan?

Omit bacon and replace heavy cream with coconut cream or cashew cream, and use vegan Parmesan alternatives or nutritional yeast.

Is it necessary to reserve pasta water?

Yes, the starchy pasta water helps loosen and emulsify the sauce, allowing it to cling beautifully to the noodles.

Can I prepare the sauce ahead of time?

Absolutely, the pumpkin sauce can be made and refrigerated for 1–2 days. Reheat gently and add pasta water as needed before combining with spaghetti.
