How to Make Keto Chicken Alfredo Spaghetti Squash Boats – Step By Step
Step 1: Preheat your oven to 400°F (200°C). Carefully cut the spaghetti squash in half lengthwise, scoop out seeds, drizzle with olive oil, and season with salt and pepper. Place the halves cut-side down on a baking sheet and roast for about 30-40 minutes until tender.
Step 2: While the squash is baking, heat the remaining olive oil in a large skillet over medium heat. Season the chicken breasts with salt, pepper, and garlic powder. Cook the chicken for 5-7 minutes per side until golden brown and fully cooked. Remove and let it rest before slicing into thin strips.
Step 3: In the same skillet, melt butter over medium heat. Add minced garlic and sauté until fragrant. Pour in the heavy cream, bring to a simmer, and add the Parmesan cheese. Stir constantly until the sauce thickens and becomes creamy, about 3-4 minutes.
Step 4: Once the squash is cooked, use a fork to scrape the inside, creating spaghetti-like strands. Fill each squash half with sliced chicken and pour the Alfredo sauce over the top. Return to the oven and bake for an additional 5-10 minutes.
Step 5: Garnish with fresh parsley and serve immediately while warm—perfectly creamy and savory, these keto boats are both healthy and full of flavor!

Recipe Success Tips & Suggestions
The true charm of this dish lies in its simplicity and adaptability. Make sure to roast the squash perfectly to maintain its stringy, pasta-like texture. For a rich flavor, opt for high-quality Parmesan cheese and fresh garlic. Love veggies? Add in sautéed mushrooms or spinach for extra nutrition. This dish can be easily adapted to suit both seasoned cooks and those new to the keto lifestyle.
Packed Protein: Boost Your Keto Chicken Alfredo
For those looking to up the ante on their protein intake, adding a handful of baby spinach or some steamed broccoli to the Alfredo sauce will not only increase nutrition but also offer a vibrant dash of color. Sneak in additional protein by incorporating crispy bacon or diced ham into the mix!
Low Carb Delight: A Tasty Variation
In pursuit of an even more low-carb variant of our beloved dish? Try swapping out the heavy cream for a full-fat canned coconut milk for a different spin on the traditional Alfredo. The tropical twist will introduce a mild sweetness and pairs beautifully with chicken while maintaining that essential low-carb appeal.
Storage Instructions
If you happen to have leftovers, don’t worry! Store the squash boats in an airtight container in the refrigerator for up to 3 days. When ready to enjoy, simply reheat in a preheated oven at 350°F (175°C) for approximately 10-15 minutes until warm through. Avoid using the microwave to prevent sogginess.
