I just nailed an Easy Butternut Squash Pasta that’s smoky, spicy and so creamy you won’t believe it’s vegan.

Jump to Recipe

I’m obsessed with this Spicy Butternut Squash Pasta because it’s smoky, creamy and actually bold enough to make me forget takeout. I love how the butternut squash sings without trying too hard, and the penne soaks up every drop.

Smoked paprika gives it that sneaky campfire note while maple sweetness stops the heat from being rude. This is one of those Easy Butternut Squash Pasta moments I keep in heavy rotation when I need dinner to feel worth eating.

Vegan Butternut Squash dinners shouldn’t be boring. This one isn’t.

Not even close. I’m making it again tonight, no shame.

seriously.

How to Make this

Print Recipe (No Advertisments)

1. Preheat oven to 425F and line a baking sheet with foil or parchment. Toss the butternut squash cubes with 2 tbsp olive oil, 1 tsp sea salt, 1/2 tsp black pepper, 1 tsp smoked paprika and 1/2 to 1 tsp crushed red pepper flakes. Spread in one layer and roast until edges brown and squash is very tender, about 25 to 30 minutes, flipping once.

2. While the squash roasts, soak 3/4 cup raw cashews for at least 4 hours or quick boil them for 10 minutes then drain. This makes the sauce super creamy.

3. Bring a big pot of salted water to a boil and cook 12 oz pasta according to package for al dente. Reserve 1 cup pasta water, then drain the pasta.

4. In a skillet over medium heat add 1 tbsp olive oil, sauté 1 small finely chopped yellow onion until soft and translucent about 5 to 7 minutes, add 3 minced garlic cloves and cook 30 to 60 seconds more until fragrant. If using thyme or sage add about 1 tsp chopped in now.

5. Put the roasted squash, sautéed onion and garlic, drained cashews, 1 cup unsalted vegetable broth, 1 to 2 tbsp nutritional yeast, 1 tbsp fresh lemon juice, 1 tbsp maple syrup (or brown sugar), and 1 tbsp vegan butter or extra olive oil into a blender. Blend until silky smooth, adding more broth or some reserved pasta water a little at a time until sauce is creamy and pourable. Taste and adjust salt, pepper, smoked paprika or crushed red pepper flakes.

6. Warm the blended sauce in the skillet you used for the onions over low heat, thin with reserved pasta water if needed to coat the pasta nicely. Stir and reheat gently, dont boil.

7. Add the drained pasta to the sauce and toss thoroughly so every piece is coated. If sauce feels thick add a splash more pasta water until you like the texture.

8. Taste and finish with a little more lemon juice or maple syrup if it needs brightness or balance, and add extra salt or crushed red pepper if you want more heat.

9. Serve hot, drizzle a little olive oil over each bowl, sprinkle chopped fresh parsley and extra thyme or sage if using. Enjoy right away, it gets best the same day.

Equipment Needed

1. Baking sheet lined with foil or parchment
2. Sharp chef’s knife
3. Cutting board
4. Large mixing bowl (for tossing squash)
5. Measuring cups and spoons
6. High-speed blender or food processor (for the cashew sauce)
7. Large pot for boiling pasta
8. Skillet or sauté pan (to cook onion and warm sauce)
9. Colander or strainer (to drain pasta and cashews)
10. Tongs or a wooden spoon for tossing and serving

FAQ

Q: Can I make this if I dont soak cashews?

A: Yes, but you'll need to boil them for about 10 minutes until soft, then drain. If you skip both soaking and boiling the sauce will be grainy not smooth. For a nut free version use 3/4 cup plain unsweetened soy yogurt or 1/2 cup cooked white beans and add a splash more broth to blend.

Q: How do I control the heat so it isnt too spicy?

A: Start with 1/2 teaspoon crushed red pepper flakes and taste after blending the sauce. You can always add more. Adding the maple syrup, lemon juice or a little extra cashew or butter helps mellow heat quick if it gets too hot.

Q: Should I roast or boil the squash?

A: Roasting gives better flavor, caramelized edges and less water so a richer sauce. Toss cubes with olive oil, smoked paprika, salt and roast at 400 F for 25 to 30 minutes. Boiling is faster but makes the sauce thinner and less flavorful.

Q: How do I get the sauce ultra creamy and not grainy?

A: Use hot broth when you blend, and blend for at least 1 to 2 minutes in a high speed blender. Scrape sides and blend again. If your blender is weak, add a bit more liquid and strain if needed. Warm the sauce gently with the pasta so it finishes silky.

Q: Can I make this ahead and reheat later?

A: Yes store sauce in an airtight container in the fridge for up to 4 days. Reheat gently on the stove adding a splash of broth to loosen it, then toss with freshly cooked pasta. The sauce may thicken in the fridge so thin it when reheating.

Q: What protein pairs well with this dish?

A: For vegan options try pan seared tempeh, crispy chickpeas, or white beans. If you eat meat, grilled chicken or spicy Italian sausage work well. Add them right before serving so they stay crisp and warm.

Spicy Butternut Squash Pasta Recipe Substitutions and Variations

Pasta: use gluten free pasta (rice or corn) if you need gluten free, or try penne made from chickpeas for more protein, or swap for short whole wheat pasta if you want nuttier flavor.
Raw cashews: sub canned coconut milk (full fat) for a creamy vegan sauce, or use soaked blanched almonds (blend well), or try silken tofu for a lower fat creamy base.
Nutritional yeast: use grated vegan Parmesan or a tablespoon of miso plus a pinch of garlic powder for umami, or just skip it and add a bit more lemon and salt to boost flavor.
Maple syrup or brown sugar: swap with agave nectar, honey if not vegan, or a splash of orange juice for natural sweetness and a bright note.

Pro Tips

1. Roast the squash on a single layer and dont skimp on high heat. It caramelizes faster at 425F so you get deeper flavor, just flip once halfway so the edges get browned but not burned.

2. Save more than you think of the pasta water. Start with 1 cup reserved but keep a little extra aside. The starchy water thins the cashew sauce without watering it down and helps it cling to penne or rigatoni.

3. Warm the blended sauce slowly before adding pasta. Boiling can make cashew sauces grainy, so reheat gently and loosen with pasta water in small splashes until it coats the noodles perfectly.

4. Taste and balance at the end. Add lemon for brightness or a touch more maple for sweetness, and adjust smoked paprika or chili flakes for heat. Small tweaks at the finish make the dish go from good to restaurant level.
