Ingredients You’ll Need

The magic in this Spaghetti Squash Lasagna Boats Recipe really comes from the mix of fresh, wholesome ingredients working together—creamy ricotta, hearty kale, melty mozzarella, and a rich turkey tomato sauce. When shopping, look for small to medium spaghetti squash—we want them easy to handle and perfectly portioned for the boats.

• Spaghetti Squash: The star ingredient that gives you “noodles” without the pasta. Look for firm, medium-sized squash for easy roasting.
• Olive Oil: This brings a lovely richness and helps caramelize the garlic and kale perfectly.
• Garlic: Fresh cloves provide a bright, aromatic base—don’t use jarred if you can avoid it!
• Baby Kale: Tender and slightly sweet, it adds freshness and color without overpowering the dish.
• Ricotta Cheese: Creamy and mild, it makes the filling extra luscious.
• Mozzarella Cheese: Melts beautifully, giving you that gooey cheesy topping we all love in lasagna.
• Salt and Lemon Juice: The perfect little accents to brighten up and season the filling.
• Ground Turkey: A lean protein that cooks up tender in the sauce; feel free to substitute ground beef or chicken.
• Crushed Tomatoes: Use a quality canned variety for that rich, simmered tomato flavor.
• Chicken or Vegetable Broth: Thins out the sauce while adding depth.
• Italian Seasonings: Oregano, parsley, and basil make the sauce taste like it simmered all day.
• Red Wine or Vinegar: These add a touch of acidity and complexity—don’t skip this if you can!

Variations

I love experimenting with this Spaghetti Squash Lasagna Boats Recipe—you can really make it your own. Whether you want to make it vegan, spice things up, or bulk it out with more veggies, this recipe is a great blank canvas.

• Vegetarian Variation: I swap out ground turkey for sautéed mushrooms and add chopped zucchini for a veggie-packed version that’s just as satisfying.
• Spicy Twist: Add red pepper flakes to the tomato sauce or mix in some spicy Italian sausage instead of turkey if you like a little heat.
• Dairy-Free Option: Use dairy-free ricotta and mozzarella alternatives, and the results are still creamy and delicious.
• Seasonal Spins: In fall, I sometimes toss roasted butternut squash or sweet potatoes into the mix for extra warmth and sweetness.

How to Make Spaghetti Squash Lasagna Boats Recipe

Step 1: Roast Your Spaghetti Squash

Preheat your oven to 350°F. Cut the squash in half lengthwise—this is easier with a sharp, sturdy knife. Scoop out all the seeds and strings (save those for roasting later if you’re feeling fancy!). Place the halves cut-side up in a baking dish. Roast them uncovered for about 50-60 minutes. You’ll know they’re ready when the flesh is tender enough to pull apart into spaghetti-like strands with a fork. Don’t rush this step; the texture makes all the difference in your lasagna boats. Once done, carefully scrape out the squash “noodles” into a large bowl, keeping those shells intact because they’ll be your boats later!

Step 2: Simmer the Savory Turkey Tomato Sauce

While the squash roasts, heat a tablespoon of olive oil over medium heat in a pan. Add minced garlic and sauté for 1-2 minutes just until fragrant—watch closely so it doesn’t burn! Next, add the ground turkey, breaking it apart as it cooks through. When it’s browned, stir in crushed tomatoes, salt, Italian seasonings, and a splash of red wine or vinegar. Let this simmer gently for 20 minutes to build rich flavor. Add broth as needed if your sauce gets too thick. Here’s a tip from my kitchen: the wine and vinegar give it that slight tang that’ll make your sauce taste gourmet even on a weeknight.

Step 3: Wilt Kale and Prepare the Ricotta Filling

In another skillet, warm olive oil over medium. Toss in minced garlic and after a minute, add baby kale. Stir it gently until the leaves just wilt—don’t overcook, or it loses that great green color and fresh flavor. Then, in a small bowl, mix the kale with ricotta cheese, a good pinch of salt, a squirt of lemon juice to brighten everything up, and half a cup of shredded mozzarella. Finally, fold in the cooked spaghetti squash strands. This blend is creamy but light, layered with lovely textures.

Step 4: Assemble and Bake Your Lasagna Boats

Now comes the fun part — spoon the squash mixture back into the squash shells, packing them generously. Top each filled boat with that rich turkey tomato sauce you simmered up, then sprinkle the remaining shredded mozzarella over everything. Crank up your oven to 425°F and bake for 10-15 minutes, just until the cheese is bubbling and golden. If you want to be fancy, a quick broil for a minute or two can add gorgeous browning, but keep a close eye! When they come out, I like to finish with a sprinkle of Parmesan, a drizzle of olive oil, fresh parsley, and a pinch of salt and pepper.

How to Serve Spaghetti Squash Lasagna Boats Recipe

Garnishes

I usually garnish these boats with a sprinkle of freshly grated Parmesan, some chopped parsley for that fresh green pop, and an extra drizzle of good olive oil to finish. Sometimes a little cracked black pepper on top really brings out the cheese flavors. These simple touches make the presentation look stunning and the flavors even better.

Side Dishes

Because this dish is so hearty, I like to keep sides light and fresh—think a crisp green salad with a tangy vinaigrette or garlic-roasted asparagus. Sometimes I serve it with warm garlic breadsticks for that extra comforting feel, but honestly, this recipe stands well enough on its own.

Creative Ways to Present

For a special dinner, I’ve decorated the boats with edible flowers or fresh basil leaves that add color and a festive vibe. You could also plate each boat on a bed of sautéed greens or place them in shallow bowls with extra sauce ladled around for an elegant touch. Perfect for a cozy dinner party!

Make Ahead and Storage

Storing Leftovers

Leftover spaghetti squash lasagna boats keep beautifully in an airtight container in the fridge for up to 3 days. I find that the flavors deepen overnight, making the next day even more delicious. Just be sure to cover your squash boats tightly to avoid drying out the shells.

Freezing

I’ve had great success freezing the assembled boats before the final cheese bake. Wrap them tightly in plastic wrap and foil, then freeze up to 2 months. When you’re ready, thaw overnight in the fridge and bake as directed—adding an extra 5-10 minutes if needed to heat through and melt the cheese perfectly.

Reheating

To reheat leftovers, I pop them in a 350°F oven for about 15-20 minutes, covered loosely with foil to keep moisture in. This way, the squash stays tender and the cheese melts back into silky perfection instead of drying out in the microwave.
