- 1/4 teaspoon black pepper: Provides a subtle heat and complexity.

How to Make Spaghetti Squash Alfredo Recipe
Step 1: Roast the Spaghetti Squash
Start by preheating your oven to 400°F (200°C). Place the halved and seeded spaghetti squash cut-side down on a baking sheet. Roasting it this way allows the flesh to soften perfectly, so when you shred it with a fork, it naturally separates into those beautiful spaghetti-like strands that form the base of our dish.
Step 2: Sauté the Garlic
While the squash roasts, heat olive oil in a large skillet over medium heat. Add the minced garlic and sauté it for 1 to 2 minutes until you can smell that delightful fragrance. This step ensures the garlic infuses its flavor without overpowering, setting a delicious tone for the sauce.
Step 3: Make the Alfredo Sauce
Pour the heavy cream into the skillet with the garlic and bring it to a gentle simmer. Add the cream cheese and stir continuously until it melts into a smooth, creamy base. Then, stir in the freshly grated Parmesan along with salt, pepper, and nutmeg. Cook the sauce for about 5 minutes so it thickens to a luscious consistency that will coat the spaghetti squash strands beautifully.
Step 4: Shred the Spaghetti Squash
Once the squash is roasted and tender, remove it from the oven and let it cool just enough to handle. Use a fork to scrape the flesh, creating those lovely strands that resemble thin noodles—this is where the magic of the Spaghetti Squash Alfredo Recipe truly shines.
Step 5: Combine and Toss
Add the shredded squash directly to your skillet with the Alfredo sauce. Gently toss until every strand is coated in that creamy, flavorful sauce. This step melds everything together so perfectly, ensuring each bite is full of delicious indulgence without feeling heavy.
How to Serve Spaghetti Squash Alfredo Recipe
Garnishes
A sprinkle of freshly chopped parsley on top of your Spaghetti Squash Alfredo Recipe not only adds a splash of vibrant green but also a fresh, herbaceous note that balances the richness of the sauce. You could also add a dash of extra Parmesan if you love a cheesy finish.
Side Dishes
This dish pairs wonderfully with simple, crisp vegetable sides like steamed broccoli or a fresh garden salad to introduce some crunch and brightness. For extra heartiness, consider serving alongside roasted chicken or garlic-sauteed shrimp, which complement the creamy sauce beautifully.
Creative Ways to Present
To elevate your presentation, serve the Spaghetti Squash Alfredo Recipe in the roasted squash shells themselves—this adds a rustic charm to your plate that’s sure to impress. Alternatively, plate it with a drizzle of truffle oil or a sprinkle of toasted pine nuts for extra texture and decadence.
Make Ahead and Storage
Storing Leftovers
Leftover Spaghetti Squash Alfredo Recipe keeps well when stored in an airtight container in the refrigerator for up to 3 days. The sauce might thicken as it cools, but a quick warm-up will bring back its creamy goodness.
Freezing
While this recipe is best enjoyed fresh, you can freeze leftovers for up to a month. Transfer them to a freezer-safe container and thaw overnight in the fridge before reheating gently to preserve the sauce’s texture and flavor.
Reheating
Heat leftovers over low to medium heat on the stove, stirring occasionally to prevent burning and to restore that luscious sauce. If the sauce feels a bit thick, add a splash of cream or milk to loosen it up without losing any creaminess.
FAQs
Can I use a different type of squash for this Alfredo recipe?
Spaghetti squash is unique for its stringy texture that mimics noodles, so using other squashes won’t give the same effect. However, you could experiment with zucchini noodles if you want a fresh twist with similar low-carb benefits.
Is this Spaghetti Squash Alfredo Recipe suitable for vegetarians?
Absolutely! The recipe uses vegetarian-friendly ingredients like cheese and cream. Just be sure the Parmesan cheese you use is free from animal-derived rennet if strict vegetarianism is important to you.
Can I make a lighter version of this recipe?
Yes! You can substitute half-and-half for the heavy cream to reduce fat content, although the sauce may be slightly less rich but still deliciously creamy.
How do I know when the spaghetti squash is done roasting?
The squash is ready when the flesh is tender and easily separates into strands when scraped with a fork. It usually takes 35 to 40 minutes at 400°F (200°C).
Can I add protein directly into the recipe?
Definitely! Adding cooked chicken, shrimp, or tossing in some steamed broccoli can transform this dish into a more balanced and filling meal without compromising its flavors.
