What is Butternut Squash Alfredo?

Butternut Squash Alfredo is a simple, cream-based alfredo sauce that incorporates cooked butternut squash. It has a reddish-orange color and a silky texture. The bold yet pleasant flavor of the butternut squash allows you to cut back on the cream and cheese, so it’s a bit less heavy than a traditional alfredo sauce.

How Do I Store Butternut Squash Alfredo Sauce?

This recipe is best served fresh, but can keep in the fridge in an airtight container for up to 3 days. Reheat in a sauté pan on the stovetop for a few minutes. You may need to add a touch of cream when reheating to return the sauce to its original consistency.

Can I Freeze Butternut Squash Alfredo?

Yes, you can freeze this recipe! In fact, you can make a few batches of this sauce and freeze them for quick weeknight meals all season long. It can be stored in freezer-grade Ziploc bags or airtight containers. Allow the sauce to completely thaw in the fridge before heating and serving.

How Do I Choose a Butternut Squash?

Look for a butternut squash that is uniform in color. It should be light beige with few cuts and scratches. Avoid squash with deep cuts or gouges. Pick a heavy squash that feels full inside. That’s how you’ll know it’s ripe.

Tips for Making Butternut Squash Alfredo

  • If you’re serving this over fettuccine, don’t overcook your pasta. The sauce will pair really well with an al dente pasta.
  • You can use an immersion blender so you don’t have to transfer your sauce to a food processor or blender.
  • You can also eat this as a soup! Serve with some toasted garlic bread and sprinkle some parmesan and parsley on top. You might have to add some chicken broth to thin it out a little.

step by step directions on how to make a cream butternut squash alfredo fettuccine pasta dish

Notes

  • Squash is ready pretty quick when you simmer it – usually within 5-10 minutes, depending on the size of your chunks. It’s ready as soon as it easily breaks with a fork.
  • If you accidentally forget to keep some of your starchy squash water, you can use water from your pasta instead. Or, you can make starch water by mixing ¾ cup boiling water with 1 ½ tbsp of cornstarch. Add the cornstarch to a bit of cold water, stir well, then quickly mix it into the boiling water.

Substitutions

  • Cream – you can use half & half or a mix of cream and chicken broth in this recipe, but your sauce will be thinner.
  • Butter – substitute margarine or another butter substitute, but your recipe will lose a bit of its richness and classic alfredo flavor.
  • Fettuccine – any pasta will work fine for this recipe, including gluten-free or vegetable-based pasta.
