How to Make Creamy Butternut Squash Spaghetti
-
Prep the Squash: Begin by peeling and cutting the butternut squash into small cubes—this helps them cook faster. Dice the onion and mince the garlic. Spread everything on a large baking sheet.
-
Roast Ingredients: Preheat your oven to 400°F (200°C). Toss the squash, onion, and garlic with olive oil, oregano, salt, and pepper. Roast for 15 minutes, or until the squash is fork-tender and golden.
-
Blend Sauce: Carefully transfer the roasted ingredients to a blender. Add the vegetable stock, half and half, and a pinch of nutmeg. Blend until smooth, adjusting the thickness with broth as needed. Taste and season with extra salt and pepper if desired.
-
Cook Pasta: In a large pot of boiling salted water, cook the spaghetti to al dente, around 7-8 minutes. Reserve a cup of pasta water before draining the rest.
-
Combine and Serve: In the pot with the drained pasta, gently reheat the sauce if necessary. Add the spaghetti, sauce, and grated Parmesan, tossing to combine. Use the reserved pasta water to achieve the desired creaminess. Serve hot, garnished with more Parmesan if you like!
Optional: Top with fresh herbs like basil for an extra pop of flavor.

Creamy Butternut Squash Spaghetti Recipe FAQs
What should I look for when selecting butternut squash?

To freeze, allow the sauce to cool completely, then transfer it to a freezer-safe container or a ziplock bag, leaving some space for expansion.

What if my sauce turns out too thick?
No worries! If your sauce is thicker than desired, simply stir in some reserved pasta water gradually until you reach the desired consistency. This will not only help in adjusting the thickness but will also reinvigorate the flavors.
