Why You’ll Love This Spaghetti Squash Alfredo

You’ll fall for this Spaghetti Squash Alfredo because it’s equal parts healthy and indulgent. The creamy sauce is comforting without being overbearing, and the squash provides that familiar pasta-like twirl with a boost of fiber and vitamins. It fits seamlessly into low-carb and gluten-free lifestyles, but truly anyone who enjoys creamy, cheesy meals will find something to love here.

Can I Use Pre-Cooked Spaghetti Squash?

Absolutely. If you’re short on time, pre-cooked spaghetti squash from the grocery store or leftovers from a previous meal work great here. Just be sure to remove any excess moisture by patting the strands dry with a paper towel before mixing with the Alfredo sauce. This keeps your final dish creamy instead of watery.

Ingredients for the Spaghetti Squash Alfredo

Spaghetti Squash Alfredo uses simple, wholesome ingredients you likely already have on hand. Here’s what you’ll need:

Spaghetti squash: The star of the dish. Once roasted, its strands mimic pasta and hold up well to creamy sauces.

Butter: Adds richness and depth to the Alfredo sauce.

Garlic: Brings aromatic warmth and essential flavor to the base.

Heavy cream: Creates the luxurious creaminess classic to Alfredo.

Parmesan cheese: The heart of the Alfredo flavor, it melts beautifully into the sauce.

Salt and pepper: To season and balance the dish.

Fresh parsley (optional): For a fresh finish and touch of color.

How To Make the Spaghetti Squash Alfredo

Step 1: Roast the Squash

Cut your spaghetti squash in half lengthwise, scoop out the seeds, and place it cut side down on a baking sheet. Roast at 400°F for about 40 minutes or until tender. Let it cool slightly, then use a fork to shred the strands into spaghetti-like ribbons.

Step 2: Make the Alfredo Sauce

In a large skillet, melt the butter over medium heat. Add the minced garlic and sauté for about 1 minute until fragrant. Pour in the heavy cream and bring it to a gentle simmer. Stir in the grated Parmesan and let it melt, stirring frequently, until smooth and creamy. Season with salt and pepper to taste.

Step 3: Combine and Serve

Add the spaghetti squash strands to the skillet and gently toss to coat in the sauce. Let everything heat through for a few minutes. Garnish with chopped parsley if using, then serve hot.

How to Serve and Store This Spaghetti Squash Alfredo

This recipe makes enough to feed about 4 people as a main course or up to 6 as a side. It pairs beautifully with a fresh salad or grilled protein and fits into many weekly meal plans.

To store leftovers, place them in an airtight container and refrigerate for up to 4 days. Reheat in a skillet over medium heat, adding a splash of cream if needed to loosen the sauce.
