Creamy Roasted Garlic Butternut Squash Pasta Recipe

Creamy Roasted Garlic Butternut Squash Pasta Recipe tastes velvety, cozy, a little sweet from the squash, and deeply savory from slow roasted garlic.

Why Make This Creamy Roasted Garlic Butternut Squash Pasta Recipe at Home

You get a super creamy sauce without heavy amounts of cream, because the roasted butternut squash does most of the work. Roasted garlic adds restaurant level flavor, but you only need a knife, a sheet pan, and a blender.

This recipe uses simple pantry ingredients and works with fresh or frozen squash. You also control the salt, the richness, and the texture, so it fits picky kids, plant lovers, and cheese fanatics.

This Creamy Roasted Garlic Butternut Squash Pasta Recipe tastes like fall in a bowl, silky and comforting without feeling heavy, and it disappears from plates every single time. ★★★★★

Ingredients You Need

Pasta

• 12 ounces short pasta
  • Good options: rigatoni, penne, fusilli, orecchiette, shells.
  • Whole wheat or chickpea pasta also works, but check the box for timing.

Roasted butternut squash and garlic

• 1 medium butternut squash
  • Aim for about 2.5 to 3 pounds whole, which gives about 4 cups cubed.
  • Use pre cut squash from the store if you want a shortcut.
• 1 whole head garlic
• 2 tablespoons olive oil
• 1 teaspoon kosher salt
• ½ teaspoon black pepper
• ½ teaspoon smoked paprika or sweet paprika
• ¼ teaspoon red pepper flakes
  • Adjust to taste or skip for kids.

Sauce base

• 1 to 1¼ cups low sodium vegetable broth or chicken broth
  • Start with 1 cup, then thin the sauce as needed.
• ½ cup half and half or heavy cream
  • Use full fat canned coconut milk for a dairy free version.
• ¼ cup grated Parmesan cheese, plus more for serving
  • Use a wedge and grate it yourself for best melt.
• 2 tablespoons butter
  • Use vegan butter if you keep it dairy free.
• 1 tablespoon fresh lemon juice
• ¼ teaspoon ground nutmeg
• Extra salt and pepper to taste

Optional mix ins

• 2 cups baby spinach or chopped kale
• ½ cup thawed peas
• ½ cup toasted walnuts or pecans, roughly chopped
• Crispy roasted chickpeas for crunch

Pantry shortcuts and notes

• Use frozen cubed butternut squash if you want to skip peeling and chopping.
• Use jarred roasted garlic if your store sells it, about 2 to 3 tablespoons.
• Use boxed stock or broth and taste before salting, since some brands run salty.
• Use pre grated Parmesan only in a pinch, since it often contains anti caking agents that fight melting.

Equipment list

• Large sheet pan
• Sharp chef’s knife and vegetable peeler
• Cutting board
• Aluminum foil
• Large pot for boiling pasta
• Colander
• Blender, food processor, or immersion blender
• Large skillet or wide pot for finishing the pasta
• Wooden spoon or silicone spatula

Tips & Mistakes

• Salt the pasta water generously so the noodles taste seasoned, not bland.
• Roast the squash until it browns on the edges, since pale squash gives a flat tasting sauce.
• Wrap the garlic head tightly in foil so it softens and caramelizes instead of drying out.
• Reserve at least 1 cup of starchy pasta water before you drain, since it helps loosen and silk up the sauce.
• Blend the sauce very smooth so it coats the pasta instead of clumping.
• Taste the sauce before you add more salt, because Parmesan and broth already add plenty.
• Add greens like spinach at the end so they wilt gently and keep a nice color.
• Reheat leftovers with a splash of broth or water so the sauce turns creamy again instead of gluey.

How to Make Creamy Roasted Garlic Butternut Squash Pasta Recipe

Prep the squash and garlic

1. Heat your oven to 400°F and line a large sheet pan with parchment or lightly oil it.
2. Peel the butternut squash, slice it in half lengthwise, scoop out the seeds, then cut it into 1 inch cubes.
3. Place the squash on the sheet pan, drizzle with 1½ tablespoons olive oil, and sprinkle with 1 teaspoon salt, ½ teaspoon black pepper, paprika, and red pepper flakes.
4. Toss everything so the cubes coat evenly and spread them in a single layer with a little space between pieces.

Roast until caramelized

1. Slice the top off the head of garlic to expose the cloves, drizzle with the remaining ½ tablespoon olive oil, and wrap it in foil.
2. Place the foil wrapped garlic on the same sheet pan or directly on the oven rack.
3. Roast the squash and garlic for 25 to 35 minutes, tossing the squash halfway, until the squash turns tender and golden on the edges.
4. Check the garlic by squeezing the head gently with tongs; it should feel very soft.

Cook the pasta

1. While the squash roasts, bring a large pot of water to a boil and salt it well.
2. Add the pasta and cook it until it reaches al dente, following the package timing as a guide.
3. Scoop out at least 1 cup of pasta water, then drain the pasta.
4. Set the pasta aside in the colander and keep the pot handy for later or use a large skillet.

Blend the roasted squash sauce

1. Squeeze the roasted garlic cloves out of the papery skins once they cool enough to handle.
2. Add the roasted squash, roasted garlic, 1 cup broth, half and half, butter, nutmeg, and Parmesan to a blender or food processor.
3. Blend until the mixture turns very smooth and creamy, scraping down the sides as needed.
4. Taste and adjust with salt, pepper, and more broth if you want a thinner sauce.

Finish the pasta in the pan

1. Set a large skillet or the empty pasta pot over medium heat and pour in the blended sauce.
2. Add the cooked pasta and toss until the sauce coats every piece, thinning with splashes of pasta water if it looks too thick.
3. Stir in spinach, peas, or other quick cooking add ins and cook 1 to 2 minutes until the greens wilt and everything heats through.
4. Squeeze in the lemon juice, taste again, and adjust seasoning with more salt, pepper, or Parmesan.

Plate and garnish

1. Spoon the Creamy Roasted Garlic Butternut Squash Pasta into warm bowls.
2. Top with extra grated Parmesan and a sprinkle of black pepper or red pepper flakes.
3. Add chopped toasted nuts or crispy chickpeas on top if you like crunch.
4. Serve right away while the sauce stays silky and hot.

Variations I've Tried

I swap the half and half for full fat canned coconut milk and skip the Parmesan for a dairy free version, then I add extra lemon juice and nutritional yeast for cheesy flavor. I add crispy roasted chickpeas or pan seared tofu cubes for more protein and texture. I stir in chopped fresh sage or thyme with the sauce for a more herb forward vibe.

I also use roasted sweet potato in place of some of the squash when I run low, which gives a slightly sweeter, deeper orange sauce. I toss in sautéed mushrooms and caramelized onions when I want a richer, more savory pasta night. I use gluten free pasta and vegan butter when I cook for gluten free and dairy free friends, and the sauce still tastes thick and luxurious.

How to Serve Creamy Roasted Garlic Butternut Squash Pasta Recipe

Serve this Creamy Roasted Garlic Butternut Squash Pasta Recipe in warm bowls and top it with extra Parmesan, black pepper, and a drizzle of good olive oil. Pair it with a crisp green salad, roasted broccoli, or simple steamed green beans for some freshness and crunch. Add garlic bread, focaccia, or warm crusty rolls if your crew loves carbs on carbs. Offer lemon wedges and red pepper flakes at the table so everyone can tweak their own bowl.

How to store

• Store leftovers in an airtight container in the fridge for up to 4 days.
• Add a splash of broth, water, or milk before you chill the pasta if it already looks very thick.
• Freeze portions in freezer safe containers for up to 2 months, and label with the date.
• Reheat gently on the stove over low to medium heat with a splash of liquid, and stir often until the sauce loosens and turns creamy again.
• Reheat in the microwave in short bursts, stirring between each burst and adding a spoonful of liquid if the sauce looks tight.
