What You Need

Ready to make Spaghetti Squash Alfredo Boats that hit all the right notes? Here’s the ingredient lineup that’s going to make this dish absolutely crave-worthy:

  • 1 medium spaghetti squash (about 3-4 pounds) – for that perfect boat shape, grab one with firm skin.
  • 2 cups heavy cream – splurge on a good quality one; it makes the Alfredo sauce extra silky.
  • 1 cup freshly grated Parmesan cheese – fresh Parmesan is a total must for max flavor.
  • 3 tablespoons butter – butter is the heart of rich sauce, so don’t skimp!
  • 3 garlic cloves, minced – garlic is the secret ingredient that takes Spaghetti Squash Alfredo Boats over the top.
  • Salt and freshly cracked black pepper – to taste, because seasoning is everything.
  • Red pepper flakes (optional) – for a subtle kick if you like a little spice.
  • Fresh parsley, chopped (for garnish) – adds that fresh pop of color and brightness.
  • Olive oil – for roasting the spaghetti squash.
  • Grated nutmeg (a pinch) – trust me, it adds a warm depth that lifts this dish.

For the freshest flavor, buy squash that’s nice and firm. If you’re grabbing Parmesan, the block is where it’s at; pre-grated loses flavor fast. You’ll find these ingredients in most grocery stores, but for bonus points, hit the international aisle for authentic Parmesan options. I like to prep the garlic ahead and stash it in a little airtight container to save time when making these Spaghetti Squash Alfredo Boats.

Pro tip: If you want to cut prep time without losing any flavor, you can buy pre-minced garlic, but fresh always tastes better here. Keep butter and cream refrigerated until just before use, and your sauce will come together perfectly smooth every time.

How to Make It

Now for the fun part: making those Spaghetti Squash Alfredo Boats come to life! Get ready to watch your kitchen fill with the smell of buttery garlic and creamy Alfredo that’s impossible to ignore.

  1. Preheat your oven to 400°F. Start by carefully slicing the spaghetti squash in half lengthwise. Scoop out the seeds and stringy bits — this step shapes your boats for stuffing.
  2. Brush each half with olive oil and sprinkle with salt and pepper. Place them cut-side down on a baking sheet lined with parchment. Roast in the oven for about 40 minutes or until the flesh is tender and you can easily scrape it into strands.
  3. Once roasted, use a fork to gently shred the flesh into spaghetti-like strands without removing the shell — these boats carry all the magic! Set the shells aside for filling.
  4. Meanwhile, melt butter in a saucepan over medium heat. Add minced garlic and sauté for about a minute till fragrant. Your kitchen is about to smell incredible.
  5. Pour in the heavy cream and bring gently to a simmer, stirring frequently. Add grated Parmesan gradually while stirring until the sauce thickens to a luscious, silky consistency.
  6. Season the Alfredo sauce with salt, pepper, and a pinch of nutmeg to deepen the flavor. If you want to turn up the heat a bit, sprinkle in red pepper flakes.
  7. Toss the shredded spaghetti squash strands into the sauce, mixing until every strand is coated in that creamy, cheesy goodness.
  8. Spoon the Alfredo-coated squash back into the roasted shells, packing them generously so every bite is bursting with flavor.
  9. Pop the filled boats back in the oven for 10 minutes, just enough to heat everything through and get a slight golden top.
  10. Garnish with chopped parsley for that fresh burst of color and a little extra zing.

Here’s how to get restaurant-quality Spaghetti Squash Alfredo Boats at home: don’t rush roasting the squash, and stir your sauce gently to avoid clumps. When it’s done, your Spaghetti Squash Alfredo Boats should look golden and gorgeous with each bite invitingly creamy and oh-so comforting.

Serving This Up

Serving Spaghetti Squash Alfredo Boats feels like a mini celebration of comfort and flavor. I usually pair mine with a crisp green salad or roasted veggies to balance the richness of the Alfredo sauce pasta alternative. A glass of chilled white wine or sparkling water with lemon brightens the meal beautifully.

These boats are a perfect centerpiece for cozy weeknight dinners and also a fantastic option for casual dinner parties. Everyone loves when you bring out a dish that looks as good as it tastes — don’t forget to snap those beautiful golden-filled boats for the ‘gram before digging in.

Love adding seasonal twists? In the fall, toss in some sautéed mushrooms and kale before stuffing; in spring, fresh peas and asparagus work wonders. Leftovers? I reheat mine in the oven wrapped in foil to keep the boats moist and creamy.
