Iโve probably said this before, but I donโt think spaghetti squash gets nearly enough love. This time of year I tend to see a whole lot of pumpkin, some butternut squash, and sometimes acorn squash is occasionally thrown into the mix too. But spaghetti squash? Not so much.
I personally love spaghetti squash. My mom used to roast it in the oven and serve it simply with butter and salt. Thatโs my mom, noodles, butter, and salt. She could live off of thatโฆand she wouldโฆif she didnโt have to eat my cooking every day.

Thanks to my mom, Iโve had a strong love for spaghetti squash since I was a kid. Itโs one of the only vegetables I feel that can truly replace real deal pasta. Iโm never bummed or left feeling unsatisfied after a spaghetti squash dinner. Itโs always so delicious.
Enter these cute little spaghetti squash lasagna boats that I love so much. These are just like your classic lasagna only made low-carb.

Here are the details
Start with the garlic. If youโve never roasted garlic before, Iโm here to tell you that itโs truly amazing. Slow roasted garlic loses itโs intense garlic flavor and instead takes on a soft sweetness. Itโs delicious and so simple to doโฆlike so simple. Just drizzle an entire head of garlic with a little olive oil, wrap in foil, and roast in the oven until the garlic turns a pretty, golden color.
And thatโs it. Then mash the garlic into a paste and stir it into the tomato sauceโฆ
Which brings me to the next step! While the garlic roasts, make the sauce. I like to use spicy Italian chicken sausage for extra flavor, but you can also use ground chicken, ground turkey, or even ground beef. All will work great. Then just add tomatoes and herbs, and simmer for a bit to thicken the sauce up. Stir in the roasted garlic. And thatโs that.
Tip: if youโre short on time, you can skip roasting the garlic, but I will say that the roasted garlic really adds such a nice flavor to the sauce.


Next, prep the spaghetti squash. I like to microwave the squash for a few minutes to make it easier to cut in half. I know all too well that cutting through spaghetti squash can be super dangerous. Microwaving the squash makes it so much easier to cut. Trust me on this.
Of course, if you donโt own a microwave, you can easily just skip the step. But I would pre-roast your squash in the oven for 15 minutes to start the cooking process.

Now, for the cheesy bรฉchamel sauce. Itโs a simple mixture of milk, fresh ricotta, fontina, and provolone cheeses. I added fresh basil and some nutmeg for warmth.
OK. Now you have all your layers, letโs assemble the spaghetti squash shell. Just layer the ragu sauce and the bรฉchamel sauce inside the spaghetti squash. Top with cheese and bake until the squash is tender and the cheese is melted and bubbling up. One word to say here, YUM.
Top with fried sage and or fresh thyme. Not necessary, but I highly recommend. Why? Because itโs GOOD, and everything is better (and prettier) topped with herbs.
I really canโt begin to express just how good these lasagna boats are. Theyโve been a favorite recipe of mine for years and I love making them every fall. They require a little cooking time, but theyโre an easy, super-cozy dinner than you can throw together any night of the week. And? They are definitely special enough to serve guests for a smaller dinner party. Everyone loves getting a personalized lasagna boat.

Some serving suggestions for you
I recommend serving these with your favorite autumn side salad, this kale salad or this brussels sprout salad would both be great options.
Or? Just serve them on their own because remember, spaghetti squash is a vegetable! And itโs SO GOOD. Buttery, saucy, and a little cheesy. All the classic flavors of traditional lasagna, just on the lighter side.
Nothing not to love! Leftovers can be stored in an airtight container in the fridge.

Roasted Garlic Spaghetti Squash Lasagna Boats

Ingredientsย
- 1 tablespoon extra virgin olive oil, plus more for drizzling
- 1 head garlic
- 3/4 pound ground spicy Italian chicken sausage or ground chicken
- 1 small yellow onion, chopped
- 1 can (28 ounce) crushed San Marzano tomatoes
- 1 dried bay leaf
- 2 teaspoons dried oregano
- 2 medium spaghetti squash, halved and seeds removed
- 1/2 cup whole milk or heavy cream
- 1/4 cup whole milk ricotta cheese
- 1/2 cup fresh basil, chopped
- 1/8 teaspoon grated fresh nutmeg
- 1 1/2 cups shredded fontina cheese or mozzarella cheese
- 1 cup shredded provolone cheese
- kosher salt and black pepper
- fresh thyme and or fried sage leaves, for serving (optional)
Instructionsย
- 1. Preheat the oven to 425 degrees F. Slice off the top portion of the garlic head to expose some of the cloves. Place the garlic on a piece of foil. Drizzle lightly with olive oil and wrap in foil. Transfer to the oven and roast until cloves are lightly browned and tender, about 20 minutes. Let cool, then squeeze the garlic out into a bowl. Mash the cloves with a fork. 2. To make the meat sauce. Heat the olive oil in a large pot over high heat. When the oil shimmers, add the chicken sausage and brown all over, about 5 to 8 minutes. Add onion and cook another 2 minutes. Reduce the heat to low, add the tomatoes, 1 cup water, the bay leaf, oregano, and a pinch each of salt and pepper. Simmer for 15 minutes or until the sauce thickens slightly. Remove the bay leaf, stir in the roasted garlic. Taste and adjust seasonings as needed.3. Meanwhile, poke a few holes into the squash with a fork and place on a plate. Microwave 3 minutes. Let cool slightly, then cut in half lengthwise, scoop out the seeds and discard.ย 4. In a medium bowl, mix together the milk, ricotta cheese, nutmeg, and basil. Season with salt and pepper. Stir in 1 cup fontina cheese and 1/2 cup provolone cheese.ย 5. Place the squash in a baking dish and season the cut sides with salt and pepper. Sprinkle the remaining fontina cheese into the bottom of each squash, then evenly divide meat sauce among the squash cavities. Now spoon the milk/cheese mix over the meat sauce. Top with the remaining provolone cheese. Cover the squash loosely with foil.ย 6. Transfer to the oven and bake 20 minutes. Remove the foil and continue baking another 15-20 minutes or until the squash is tender and the cheese is golden brown on top. The squash will seem a little soupy, this is OK.ย 7. Let the squash sit 5 minutes, then use a fork to scrape the squash into strands, mixing the meat and cheese with the squash. Serve topped with thyme and sage.

I added a bit more ricotta ,as well! Garlic salt,too! I had 2 really big squashes, so added couple minutes for microwave and baking. (Great tip to make cutting the squash easier w micro btw!) I think mixing it all up after baking is best! Yum!
Thanks so much, Ryan! Glad to hear this recipe was enjoyed, I appreciate you making it!
Do you think you could replace some of the mozzarella/fontina or all with Havarti cheese? I just have some of it left and don’t want to waste things.

Hi Kate,
Wonderful!! Love to hear that your kiddos enjoyed this recipe, thanks a lot for giving it a try! xT
Very good but long prep time. Carve out an hour to prepare and then baking time is 20-30 min longer than suggested. Really like the way spaghetti squash peels off and mixes with cheese and tomato sauce. Healthier version of โlasagneโ.
Hi Syl,
Thanks a lot for trying this recipe and sharing your feedback! So sorry this took much longer than expected! xT
Made this for Valentineโs dinner for hubby! Very good! I put more ricotta and less whole milk. Added chopped spinach to get more veggies. Made more tomato sauce than I used but great to freeze for another dinner.
Hi Lori,
Fantastic! I appreciate you making this recipe and your comment! So glad it turned out well for you:)
