Whether you’re new to spaghetti squash recipes or a seasoned pro looking for a fresh take, I promise this Spaghetti Squash Alfredo Boats will quickly become a favorite in your kitchen too.
What You’ll Need for This Spaghetti Squash Alfredo Boats:

- 1 medium spaghetti squash (about 3 pounds): You can find this at most grocery stores, often in the produce section near winter squash.
- 2 cups heavy cream: Don’t have heavy cream? Full-fat coconut milk can be a lovely swap for a dairy-free twist in this Spaghetti Squash Alfredo Boats.
- 1 cup freshly grated Parmesan cheese: Freshly grated always gives the best melt and flavor. Pre-grated works well in a pinch to keep things speedy.
- 2 tablespoons unsalted butter: This adds richness. You can use olive oil if that’s what you have on hand.
- 3 cloves garlic, minced: Garlic is a must for any good alfredo sauce dish, bringing that savory kick.
- Salt and freshly ground black pepper, to taste: Simple seasoning to highlight flavors.
- Optional: ½ teaspoon Italian seasoning or fresh herbs like parsley or basil: I always add a bit extra for a fresh, earthy note in my Spaghetti Squash Alfredo Boats.
This recipe uses simple, approachable ingredients because I believe great baking – or cooking – should be easy to start and affordable to enjoy. Spaghetti squash is a fantastic base for healthy pasta alternatives since it’s low in carbs but high in nutrients. Plus, it roasts right in its skin, cutting down on cleanup and making your kitchen smell simply amazing.
For time-saving, I like to prep the garlic and measure out my cheeses while the squash is roasting. It’s a small multitasking trick that helps this dish come together faster. If you want to prep ahead, the sauce can be made a day before and reheated gently. Storing your Parmesan in an airtight container in the fridge keeps it fresh longer, and some fresh garlic can last a couple of weeks if stored in a cool, dry place.
Here’s my little trick that makes this Spaghetti Squash Alfredo Boats extra wonderful: once the squash has roasted and you’ve scraped out the strands, I toss them with a bit of olive oil before mixing in the sauce. This step helps the sauce cling deliciously, making every bite creamy and satisfying. It’s a small step that lifts this dish into a family favorite you will want to bake again and again.
How to Make This Spaghetti Squash Alfredo Boats:
- Preheat your oven to 400°F (200°C). Place your spaghetti squash on a baking sheet. I slice mine in half lengthwise—this is a key step for your Spaghetti Squash Alfredo Boats to roast evenly. Don’t forget to scoop out the seeds once it’s halved.
- Roast the squash cut-side down for about 40 minutes. Your kitchen will start to smell wonderful as the squash softens and edges caramelize. If your squash looks golden and tender when poked with a fork, you’re on track.
- While the squash roasts, start on your alfredo sauce. Melt butter in a saucepan over medium heat. Add minced garlic and cook until fragrant, about 1-2 minutes. This simple cream sauce base is where all the magic starts for your Spaghetti Squash Alfredo Boats.
- Pour in the heavy cream. Bring it to a gentle simmer—don’t boil—and stir frequently. Let it thicken slightly for about 5 minutes. This slow heat ensures your cream sauce stays silky smooth.
- Stir in the grated Parmesan cheese and Italian seasoning (if using). Keep stirring until the cheese melts into a luscious sauce. Season with salt and pepper to taste. If your sauce looks too thick, add a splash of milk or broth to loosen it.
- Remove the squash from the oven. Using a fork, scrape the flesh into strands right inside the skins. Toss the strands lightly with olive oil so the cream sauce coats perfectly.
- Fill the squash shells with your creamy alfredo mixture. This is where your Spaghetti Squash Alfredo Boats really come together.
- Optional: sprinkle a little more cheese on top and pop back into the oven under the broiler for 2-3 minutes until golden and bubbly. Watch carefully to avoid burning.
- Serve immediately and enjoy. This recipe takes about an hour from start to finish, but the results are so worth it!
While your Spaghetti Squash Alfredo Boats bakes, it’s a perfect time to tidy up or enjoy a cup of tea as the creamy aroma fills your home. This ease and simplicity are big reasons I bake this so often. If you want to switch things up, you can toss in cooked chicken, mushrooms, or spinach for a heartier stuffed spaghetti squash.
Serving Your Spaghetti Squash Alfredo Boats:

I love serving my Spaghetti Squash Alfredo Boats with a crisp green salad to balance the creaminess. Something simple like arugula with lemon vinaigrette really cuts through the richness. A side of roasted vegetables or garlic bread also pairs beautifully, making this an easy meal that feels both indulgent and fresh.
These boats are perfect for cozy dinners at home, sharing with friends, or even making ahead for a nourishing weeknight treat. For a fun twist, sprinkle fresh herbs or a handful of toasted pine nuts on top. It adds a lovely texture and fresh pop.
Leftovers? No problem! I reheat these gently in the oven to keep the edges crisp, or microwave with a little extra cream to bring back that silky sauce. Come winter, swapping out herbs for sage and adding a pinch of nutmeg brings a festive touch to this already comforting dish.

Fresh is best, but you can use frozen cooked spaghetti squash. Just thaw and drain excess moisture before mixing with the sauce. - How can I adjust this Spaghetti Squash Alfredo Boats for different pan sizes?
