Ingredients You’ll Need
The blend of roasted spaghetti squash, tender chicken, and a luscious light Alfredo sauce is where all the magic happens. When you pick your spaghetti squash, look for one that feels heavy for its size—that means it’s packed with moisture and will roast up beautifully.
- Spaghetti squash: This veggie substitutes pasta with those fun, spaghetti-like strands once cooked.
- Extra-virgin olive oil: Adds flavor and helps soften the shallots perfectly.
- Shallots: Milder and sweeter than onions, giving the sauce a delicate base.
- Garlic cloves: Essential for that savory depth.
- All-purpose flour: Helps thicken the sauce without it getting gloopy.
- 2% reduced-fat milk: Keeps the sauce creamy but lighter than heavy cream.
- Fresh lemon juice: Brightens the sauce and balances the richness.
- Parmesan cheese: Real sharpness and umami, key for authentic Alfredo flavor.
- Kosher salt and black pepper: Seasoning to bring everything together.
- Shredded rotisserie chicken: A time-saver that adds juiciness and protein.

- Spicy Kick: Sprinkle in a pinch of red pepper flakes to the sauce if you want to add some warmth—it’s a welcome surprise every time!
- Protein Swap: You can swap the chicken with cooked shrimp or even crumbled turkey sausage for another variation I’ve enjoyed.
How to Make Skinny Chicken Alfredo Spaghetti Squash Boats Recipe
Step 1: Roast the Spaghetti Squash
Start by preheating your oven to 400°F. Now, grab a large, sharp knife and carefully cut the spaghetti squash lengthwise, from stem to tail. This can be intimidating at first—I always place it on a damp towel to keep it steady. Lightly coat the inner flesh with cooking spray or a touch of olive oil, then place each half cut-side down on a baking sheet. Roast it for 30 to 40 minutes until the flesh feels tender when you poke it with a fork. This roasting step is crucial because that’s what gives you those beautiful, fork-tender “noodles.” Let the squash cool just enough so you can handle it safely in the next step.
Step 2: Prepare the Alfredo Sauce with Chicken
While the squash roasts, heat your olive oil in a large skillet over medium heat. Toss in the chopped shallots and minced garlic—this combo will fill your kitchen with the most inviting aroma—and cook for about 3 minutes until soft but not browned. Sprinkle in the flour and stir constantly for another 2 minutes; this step helps the sauce thicken without lumps. Then, slowly whisk in the milk, making sure the mixture stays silky smooth. Let it simmer gently for 3 to 4 minutes until it thickens to just the right creamy consistency. Off the heat, whisk in fresh lemon juice, Parmesan cheese, salt, and pepper. Finally, stir in the shredded rotisserie chicken—you’ll love how tender and flavorful this makes the sauce without extra effort.
Step 3: Combine Squash Strands with Alfredo Mixture
Take the roasted spaghetti squash halves and carefully scoop out the seeds—this is an easy step but important for texture. Using a fork, gently scrape the flesh to create those classic spaghetti-like strands, then mix them into your warm chicken Alfredo sauce. This combination makes the filling hearty yet light—a perfect balance that I love to dig into!
Step 4: Fill and Bake the Squash Boats
Spoon the chicken Alfredo mixture evenly into each spaghetti squash half, filling them up nicely. Sprinkle shredded mozzarella cheese over the top for that irresistible, melty finish. Pop them back into the oven for 10 minutes to warm through and melt the cheese. For a final touch, switch your oven to broil on high and broil for 2 minutes until the cheese turns golden with a few enticing spots. Keep a close eye here to avoid burning—broilers work fast! When done, garnish with freshly chopped parsley for a bright pop of color and fresh flavor.
Pro Tips for Making Skinny Chicken Alfredo Spaghetti Squash Boats Recipe
- Squash Cutting Safety: Always stab a knife in the middle of the squash first and twist to crack it before slicing to avoid accidents.
- Smooth Sauce Magic: Whisk the flour and shallot mixture constantly to prevent lumps and get that silky Alfredo texture.
- Timing for Broil: Keep the oven door slightly ajar and watch the cheese closely; it can go from golden to burnt in seconds.
- Avoid Soggy Squash: Roast the squash cut-side down to keep it from becoming watery and maintain those perfect strands.
How to Serve Skinny Chicken Alfredo Spaghetti Squash Boats Recipe
Garnishes
I usually keep it simple with freshly chopped parsley because the bright green really lifts the plate visually and adds a gentle herbal note that complements the creamy sauce beautifully. Sometimes I’ll add a little twist of lemon zest for some extra zing—trust me, it’s worth it!
Side Dishes
Since this recipe is already so filling, my go-to sides are light and crisp—think a simple arugula salad with lemon vinaigrette or roasted asparagus tossed with a bit of garlic and olive oil. They balance out the richness perfectly.
Creative Ways to Present
For family gatherings, I’ve served these boats right on individual plates with a sprinkle of extra Parmesan and a drizzle of truffle oil for a decadent touch. I’ve also laid them out on a large platter garnished with fresh herbs and lemon wedges when hosting friends—it always feels special and inviting.
Make Ahead and Storage
Storing Leftovers
After dinner, I store any leftover boats in an airtight container in the fridge. You can keep them whole or scoop out the filling into a separate container—either way, they stay fresh for up to three days. This is such a lifesaver on busy nights.
Freezing
I’ve frozen the filling mix before and found it thaws beautifully with minimal texture change. Just pack the mix tightly in a freezer-safe container or bag, then thaw overnight in the fridge. I usually skip freezing the assembled boats because the squash texture isn’t quite the same after thawing.
Reheating
To reheat, I like to warm the boats in the oven at 300°F—this keeps the cheese melty and the squash strands separated, avoiding any sogginess. Microwaving the filling on a plate works too if I’m in a rush; just cover it and heat in short bursts to keep it creamy and delicious.
FAQs
-
Can I use fresh chicken instead of rotisserie?
Absolutely! You can cook chicken breasts or thighs seasoned and shredded at home, then stir them into the Alfredo sauce. Rotisserie chicken just saves time and adds a lovely roasted flavor, but fresh cooked works just as well.
-
Is spaghetti squash hard to prepare?
It can feel intimidating the first time, mainly because of the cutting part. Using a sharp knife and stabilizing the squash on a towel helps a lot. Once roasted, the rest is easy and quite rewarding because the strands separate like spaghetti!
-
Can this recipe be made vegan?
Yes! Swap the milk for unsweetened plant milk, parmesan for nutritional yeast, and mozzarella for your favorite vegan cheese. You can substitute the chicken with sautéed mushrooms or seasoned tofu for protein.
-
How can I tell when the spaghetti squash is perfectly cooked?
It’s ready when the flesh is tender and easily shredded into strands with a fork. If the squash resists and feels tough, roast it a bit longer in 5-minute increments until it softens.

This Skinny Chicken Alfredo Spaghetti Squash Boats Recipe has become a staple in my kitchen because it hits that sweet spot of indulgence and lightness.

Ingredients
Spaghetti Squash
- 1 medium-sized spaghetti squash
Alfredo Sauce and Filling
- 2 Tbsp. extra-virgin olive oil
- 1/2 cup chopped shallots
- 3 garlic cloves, minced
- 2 Tbsp. all-purpose flour
- 2 cups 2% reduced-fat milk
- 2 Tbsp. fresh lemon juice
- 1/4 cup grated Parmesan cheese
- 1/2 tsp. kosher salt
- 1/2 tsp. freshly ground black pepper
- 2 cups shredded rotisserie chicken
- 1/2 cup shredded mozzarella cheese
- Finely chopped parsley for garnish
Instructions
- Preheat and Prepare Squash: Preheat your oven to 400°F. Using a large knife, carefully cut the spaghetti squash lengthwise from stem to tail. Lightly coat the flesh with cooking spray or olive oil, then place the squash cut-side down on a baking sheet. Roast in the oven for 40 minutes, or until the squash is tender when pierced with a fork. Remove and let cool until safe to handle.
- Make Alfredo Sauce: While the squash is roasting, heat 2 tablespoons of olive oil in a large skillet over medium heat. Add the chopped shallots and minced garlic, sautéing for about 3 minutes until softened. Whisk in 2 tablespoons of all-purpose flour and cook for 2 minutes to form a roux. Slowly add 2 cups of 2% reduced-fat milk in a steady stream, whisking continuously until the mixture is smooth. Allow to simmer gently for 3 to 4 minutes until thickened. Stir in 2 tablespoons fresh lemon juice, 1/4 cup grated Parmesan cheese, 1/2 teaspoon kosher salt, and 1/2 teaspoon freshly ground black pepper. Remove from heat and mix in the shredded rotisserie chicken.
- Prepare Spaghetti Squash Strands: Slice the cooled spaghetti squash open and scrape out the seeds, discarding them. Use a fork to scrape out the spaghetti-like strands into a bowl. Combine the squash strands with the prepared chicken Alfredo mixture, stirring gently to combine.
- Assemble and Bake: Evenly fill the hollowed-out squash shells with the chicken Alfredo and spaghetti squash mixture. Sprinkle 1/2 cup shredded mozzarella cheese evenly over the top. Return the filled squash boats to the oven and bake at 400°F for 10 minutes to melt the cheese.
- Broil for Finish: Switch your oven setting to broil on HIGH and broil the squash for an additional 2 minutes or until the mozzarella is golden and bubbly in spots. Watch carefully to avoid burning.
- Garnish and Serve: Remove the stuffed squash from the oven and garnish with finely chopped fresh parsley. Serve immediately for best flavor and texture.
Notes
- MAKE DAIRY-FREE: Substitute the 2% reduced-fat milk with unsweetened plain almond or cashew milk, and replace Parmesan cheese with nutritional yeast for a cheesy flavor. Use your favorite brand of shredded vegan mozzarella cheese to finish.
- STORE: Store the stuffed squash boats in an airtight container or leave assembled in their shells. They keep refrigerated for up to 3 days.
- REHEAT: Warm in the oven at 300°F until heated through if keeping in the shells. Alternatively, microwave squash mixture on a plate until warm.
