Oh my goodness, you are going to LOVE these spaghetti squash lasagna boats! If you’re like me, you adore the cheesy, saucy goodness of lasagna but sometimes want to skip the heavy carbs. Well, I’ve totally cracked the code! This recipe takes those classic Italian flavors you crave and packs them into a fun, edible boat made from spaghetti squash. Seriously, it’s a game-changer for weeknight dinners. I stumbled upon this idea years ago when I was trying to lighten up some of our family favorites, and after a few tweaks, this became our go-to. It’s just proof that comforting food can also be incredibly smart and delicious!

Why You’ll Love These Spaghetti Squash Lasagna Boats

Seriously, you won’t believe how creamy and satisfying the ricotta filling is, all tucked into those tender squash strands! It’s pure comfort food. Swap out the pasta for spaghetti squash and you’ve got a winner! It’s a fantastic way to enjoy all the lasagna flavor without all the carbs, making it great for anyone watching their intake.

It’s such a fun way to eat veggies, too! Kids and adults alike get a kick out of these. They’re like personal edible bowls, and who doesn’t love that? It makes eating your vegetables feel like dessert. Plus, with a little prep ahead or a streamlined process, these can absolutely grace your table on a busy weeknight. They’re so much better than takeout!

And the best part? They are totally customizable! Don’t like sausage? Add ground beef, or maybe some spinach! You can really tweak the filling to suit exactly what you’re craving. They’re also meal prep friendly. Prep the squash and the filling a day ahead, and you’re basically halfway done when it’s time to bake. Major win for busy schedules!

Gather Your Ingredients for Spaghetti Squash Lasagna Boats

Alright, let’s get our ingredients lined up! This is the fun part where we gather all the goodies that will transform spaghetti squash into a lasagna dream. You’ll need two medium spaghetti squashes, about 2-3 pounds each, just to make sure we have nice sturdy boats. We’ll also need a tablespoon of olive oil, a teaspoon of salt, and half a teaspoon of black pepper to get those squash halves ready for roasting. For the creamy filling, grab 15 ounces of ricotta cheese, one large egg, half a cup of grated Parmesan, a quarter cup of fresh parsley, and those little flavor boosters: a quarter teaspoon each of garlic powder and onion powder. Don’t forget a 24-ounce jar of your favorite marinara sauce and a cup of shredded mozzarella. Oh, and if you’re feeling it, a pound of cooked Italian sausage or ground beef is a fantastic addition for extra heartiness!

Ingredient Notes and Substitutions

When picking out squash, look for ones that feel heavy for their size and have firm skin – no soft spots! For the marinara sauce, use one you genuinely love the taste of because it really shines here. If you’re not a big fan of ricotta, or just want to mix things up, you can totally try cottage cheese instead! Just drain off any excess liquid. Honestly, I’ve tried both, and while ricotta gives it a super smooth texture, cottage cheese adds a nice little tang. It’s a great swap when you’re thinking about things like “ricotta vs cottage cheese in lasagna boats.” And for my Italian sausage lovers out there, feel free to use mild or hot, or even swap it for ground beef or turkey. Whatever makes your taste buds sing! I have a whole collection of delicious side dishes that would be perfect with this, but today we’re focusing on these amazing boats!


**How to Prepare Spaghetti Squash Lasagna Boats: Step-by-Step**

Okay, let’s get down to business! Making these spaghetti squash lasagna boats is so much easier than you might think, and it’s honestly the best way to whip up a comforting, Italian-inspired meal that’s actually good for you. We’re going to break it down into a few simple steps, so don’t worry if you’ve never tackled spaghetti squash before. Trust me, after this, you’ll be a total pro! It’s perfect for a busy night, maybe paired with a quick weeknight dinner. It’s also super forgiving, kind of like my sheet pan chicken and vegetables – a little extra time here or there won’t ruin everything!

Tips for Perfect Spaghetti Squash Lasagna Boats

Alright, so you’ve got your ingredients ready to go! To make sure these spaghetti squash lasagna boats turn out absolutely perfect every single time, a few little secrets come to mind. First off, when you’re picking out your squash, just give it a good squeeze – you want it to feel firm and heavy for its size, no squishy spots! That’s your best bet for good strands later on. I also like to make sure my marinara sauce isn’t *too* chunky, so it spreads nicely. And if your ricotta seems a little watery, just give it an extra minute to drain in a fine-mesh sieve before mixing. Little things like these really make a difference, trust me! You’ll find that these tips help ensure your boats are perfectly tender and packed with flavor, making them a real showstopper, perhaps even a fun starter from my appetizers and snacks collection!

Make-Ahead and Storage for Spaghetti Squash Lasagna Boats

Can we talk about making life easier? Because these spaghetti squash lasagna boats are total superstars for meal prep! You can totally roast the spaghetti squash halves and get that delicious cheese filling mixed up a day ahead of time. Just store them in separate airtight containers in the fridge. Then, when it’s dinner time, all you have to do is assemble everything and bake! So simple, especially if you’re looking for fun make-ahead meal prep options. Once baked, you can store any leftovers in an airtight container in the fridge for about 3-4 days. To reheat, just pop them back in the oven at around 350°F (175°C) until they’re warmed through, or even a quick zap in the microwave works too. They stay super tasty!

Nutritional Information for Spaghetti Squash Lasagna Boats

Now, let’s talk numbers for these delicious spaghetti squash lasagna boats! Keep in mind that these are just estimates, okay? Because we all know that using different brands of marinara or cheese can change things up a bit. But generally speaking, one boat will run you around 350 calories. You’re looking at about 25 grams of carbohydrates, with 5 grams of that being fiber, so that’s pretty great for a low-carb meal! Plus, you get a solid 20 grams of protein to keep you feeling satisfied. It’s a really balanced and healthy way to enjoy a classic comfort food flavor!

Frequently Asked Questions About Spaghetti Squash Lasagna Boats

Got questions about these amazing spaghetti squash lasagna boats? I’ve got answers! It’s always good to know the little tricks so your dishes turn out perfect. Here are a few things folks often ask me:

Can I use a different type of squash?

While spaghetti squash is totally the star here because of its “noodles,” you could experiment with acorn squash if you wanted! Just know the texture will be a bit different – a little softer and creamier, not so stringy. It’s still delicious, though, especially if you’re aiming for those cheesy squash lasagna boats vibes!

How do I prevent the squash from being watery?

Great question! This is key for great texture. Make sure you roast the squash cut-side down, as directed. This lets any excess moisture escape. Also, after you scrape out those strands, you can gently press them with a paper towel to get rid of any extra water clinging to them. It makes a big difference!

Can I make this vegan?

You sure can! To make these vegan, swap out the ricotta for a plant-based ricotta alternative (you can even make your own with cashews or tofu!). Use a vegan Parmesan and mozzarella, and make sure your marinara sauce doesn’t contain any hidden dairy or meat products. Easy peasy!

Can I add more veggies to the filling?

Absolutely! Feel free to stir in some cooked spinach, finely chopped mushrooms, or even some extra shredded zucchini along with the ricotta. Just make sure whatever veggies you add are cooked and have had any excess moisture squeezed out so they don’t make the filling too watery. It’s another way to make these boats your own! You could even pair them with a nice big salad, similar to how I might serve some of my soups and salads.

Ingredients

Scale
  • 2 medium spaghetti squash (about 23 lbs each)
  • 1 tbsp olive oil
  • 1 tsp salt, divided
  • 1/2 tsp black pepper, divided
  • 15 oz ricotta cheese
  • 1 large egg, lightly beaten
  • 1/2 cup grated Parmesan cheese
  • 1/4 cup chopped fresh parsley
  • 1/4 tsp garlic powder
  • 1/4 tsp onion powder
  • 1 (24 oz) jar marinara sauce
  • 1 cup shredded mozzarella cheese
  • Optional: 1 lb cooked Italian sausage or ground beef

Instructions

  1. Preheat your oven to 400°F (200°C).
  2. Cut each spaghetti squash in half lengthwise. Scoop out the seeds and stringy pulp.
  3. Brush the cut sides of the squash with olive oil and season with 1/2 tsp salt and 1/4 tsp pepper.
  4. Place the squash halves cut-side down on a baking sheet.
  5. Roast for 40-50 minutes, or until the squash is tender when pierced with a fork.
  6. Let the squash cool slightly, then use a fork to scrape out the spaghetti-like strands. Leave the strands in the squash shells.
  7. While the squash roasts, prepare the ricotta filling. In a medium bowl, combine ricotta cheese, egg, Parmesan cheese, parsley, garlic powder, onion powder, remaining 1/2 tsp salt, and 1/4 tsp pepper. If using, stir in cooked meat.
  8. Spread about 1/4 cup of marinara sauce over the strands in each squash half.
