It’s such a rewarding recipe to come back to—you can make it your own, and it’ll never let you down. Let’s dive into the ingredients you’ll need to get started.
What You’ll Need for This Spaghetti Squash Alfredo Boats:
Here’s all you’ll need to make delicious Spaghetti Squash Alfredo Boats that your family or guests will love. This keeps ingredients simple because good cooking should be accessible and not intimidating.
- 1 medium spaghetti squash (about 3 to 4 pounds)
- 2 cups heavy cream (or half-and-half for a lighter option)
- 1 cup grated Parmesan cheese (freshly grated if possible)
- 3 tablespoons unsalted butter
- 3 cloves garlic, minced
- Salt and black pepper, to taste
- Fresh parsley or basil, chopped (optional, for garnish)
- 1/2 teaspoon nutmeg (this little touch really brings out the sauce’s flavor)
- 1 cup shredded mozzarella or fontina cheese (for topping)
- Olive oil (for roasting the squash)
Don’t have heavy cream? A mixture of milk and cream cheese works perfectly in this Spaghetti Squash Alfredo Boats recipe too. And if Parmesan isn’t on hand, Pecorino Romano is a great substitute.
You can find most of these ingredients at your local grocery store year-round. Spaghetti squash is usually available in the produce section, especially in fall and winter, but I’ve seen it stocked quite regularly in many markets.
This Spaghetti Squash Alfredo Boats is also economical since you’re stretching a few rich ingredients over a big veggie base. For quick prep, I like to halve and roast my spaghetti squash while prepping the sauce so nothing sits waiting too long. Store any leftover Parmesan and butter in the fridge and keep your herbs fresh in a small glass of water on the counter for easy use.
Here’s my little secret that makes this Spaghetti Squash Alfredo Boats extra special: a pinch of nutmeg in the Alfredo sauce—it adds warmth without being sweet. Ready to see how it all comes together in the kitchen?
How to Make This Spaghetti Squash Alfredo Boats:
Let’s cook this Spaghetti Squash Alfredo Boats step by step—it’s easier than it looks, and I’m here to walk you through it.
- Preheat your oven to 400°F. Drizzle olive oil over the halved spaghetti squash, rubbing it over the flesh, and sprinkle with salt and pepper. Lay the halves cut side down on a baking sheet.
- Roast the squash for 40-45 minutes. You’ll know it’s ready when the flesh is tender and pulls away in strands with a fork easily. This is the step where patience pays off with your Spaghetti Squash Alfredo Boats—the squash needs to be cooked through to get the perfect texture.
- While the squash roasts, start your Alfredo sauce. In a heavy skillet over medium heat, melt the butter. Add minced garlic and sauté until fragrant but not browned, about 1 minute.
- Add the heavy cream and nutmeg. Bring to a gentle simmer, stirring occasionally. Let this cook for about 4-5 minutes until it starts to thicken slightly.
- Mix in the Parmesan cheese, stirring until smooth. Season with salt and pepper to taste. If your sauce feels too thick, add a little more cream or milk to loosen it—a great time-saving shortcut is to prepare this sauce while the squash is roasting.
- Remove the spaghetti squash from the oven and let it cool slightly. Using a fork, scrape out the flesh into long strands, keeping it mostly inside the halves for stuffing. If your Spaghetti Squash Alfredo Boats looks like this—a little loose or watery when scraping—that’s okay. Drain excess moisture by letting it sit briefly or blot with a paper towel.
- Mix the spaghetti squash strands with the Alfredo sauce gently, then spoon the mixture back into the squash shells. Sprinkle shredded mozzarella or fontina cheese on top.
- Return the stuffed boats to the oven and bake for another 15 minutes. You want the cheese to melt and get bubbly, with a nice golden color.
- Garnish with fresh chopped parsley or basil before serving. Your kitchen will smell amazing when this Spaghetti Squash Alfredo Boats is ready—creamy, garlicky, and inviting.
From start to finish, this Spaghetti Squash Alfredo Boats takes about an hour, but much of that is hands-off roasting and baking. While it cooks, you can tidy up or set the table, making great use of your time.
Through the many times I’ve made this recipe, I’ve learned that roasting the squash cut side down helps steam the flesh for tender strands, and stirring the sauce gently prevents it from getting grainy. You’ll be surprised how simple and satisfying this meal is.
Serving Your Spaghetti Squash Alfredo Boats:
This Spaghetti Squash Alfredo Boats truly shines when served as a hearty yet healthy low carb meal. I love pairing it with a crisp green salad tossed with lemon vinaigrette, or simple roasted broccoli—both add fresh contrasts to the creamy Alfredo sauce pasta.
For occasions, it works beautifully as a cozy weeknight dinner or a vegetarian main dish for gatherings. It’s a conversation starter, especially since stuffed spaghetti squash feels special but isn’t a fuss to prepare.
If you want to get creative, these boats are perfect for seasonal variations—try adding sautéed mushrooms or spinach into the Alfredo sauce for an extra veggie boost. When the season calls for it, roasted cherry tomatoes make a colorful, juicy topping.
Leftovers? I like to scoop the filling out and toss it with pasta or crisp it up in a skillet for a quick next-day meal. Sometimes, I even turn it into a vegetarian alfredo boats pasta bake—just add breadcrumbs and bake until crunchy on top.

Common Questions About This Spaghetti Squash Alfredo Boats:

Absolutely! You can roast the spaghetti squash and prepare the Alfredo sauce up to two days in advance. Store the strands and sauce separately in airtight containers in the fridge, then assemble and bake just before serving.
2. What’s a good substitute for heavy cream in this Spaghetti Squash Alfredo Boats?
Half-and-half or a mix of whole milk and cream cheese works well if you want a lighter sauce. Just expect a slightly less rich result but still delicious.

Spaghetti squash sizes vary, so plan about one medium squash per 2-3 people depending on appetite. You can easily halve or double the sauce ingredients to match your squash amount.

Definitely! Cooked chicken, shrimp, or even crispy bacon make great additions. For a vegetarian Alfredo boat, try adding sautéed mushrooms or broccoli.

If the squash isn’t roasted long enough or is too dense, it can hold moisture. Make sure to roast it until tender. You can also pat it dry with paper towels before mixing with sauce.

Simple! Use a mild cheese like mozzarella and reduce garlic slightly. Kids usually love the creamy texture and cheesy topping.
