Low Carb Spaghetti Squash Lasagna Boats with Broccolini

Imagine pulling a warm, bubbling dish directly from your oven. This recipe delivers the rich, savory flavor of classic lasagna. However, it swaps traditional noodles for tender spaghetti squash strands.

Consequently, you get a beautiful contrast of textures. The squash offers a delicate, slightly sweet bite. Meanwhile, the broccolini adds a wonderful earthy crunch.

Ultimately, your family will absolutely adore this comforting meal. It provides all the cheesy goodness of Italian comfort food. Therefore, you can satisfy your cravings without any heavy carb crash later.

Recipe Highlights

This dish stands out because it reimagines comfort food. Specifically, we use the natural squash skin as a built-in baking boat. Consequently, this clever trick reduces cleanup time significantly.

Additionally, the vibrant green broccolini boosts the nutritional profile beautifully. The garlic-infused ricotta filling provides rich, creamy pockets of joy throughout. Finally, the golden, melted mozzarella layer on top seals in all the moisture.

Why Make My Spaghetti Squash Lasagna

• Ready quickly because the squash cooks efficiently in the microwave before baking.
• Beginner friendly since it requires absolutely no complicated pasta rolling or layering.
• No fancy equipment is needed, meaning you only need a baking sheet and a fork.
• Family approved because the bubbly cheese top easily wins over picky eaters.
• Budget friendly as it relies on affordable, simple garden vegetables and basic dairy.

Does Spaghetti Squash Lasagna Fit a Keto Lifestyle?

Yes, this dish fits a keto lifestyle exceptionally well. Spaghetti squash naturally contains far fewer carbs than traditional flour pasta. Specifically, one serving of this lasagna delivers only about 9 grams of net carbs. We also load the filling with high-fat ricotta and mozzarella cheeses. Therefore, you can enjoy a hearty portion while easily maintaining your ketosis.

Consequently, it has earned a permanent spot on my weekly meal rotation.

Key Ingredients

I’ve included everything below to make this recipe easy to follow at home. For the full printable recipe instructions and ingredient quantities, scroll to the Recipe card at the bottom of this post.

Spaghetti Squash: This is my absolute favorite low-carb pasta alternative. It provides the perfect stringy texture that mimics traditional spaghetti noodles wonderfully.

Broccolini: I prefer using these tender, sweet stalks over regular broccoli. They chop up beautifully and add a delicate, peppery crunch to every single bite.

Ricotta Cheese: This creamy dairy staple forms the luxurious base of our filling. It adds a classic, velvety lasagna texture that binds the ingredients together.

Garlic: Freshly minced cloves are essential for adding a punchy, aromatic depth. They elevate the mild cheeses and bring a classic Italian warmth.

Mozzarella Cheese: I always select low-moisture mozzarella for the ultimate gooey melt. It creates that beautiful, golden-brown crust on top of each boat.

How to Make Spaghetti Squash Lasagna with Broccolini

I’ve included everything below to make this recipe easy to follow at home. For the full printable recipe instructions and ingredient quantities, scroll to the Recipe card at the bottom of this post.

1. Cut the spaghetti squash in half lengthwise and scrape out the seeds completely.
2. Microwave the halves cut-side down for 10 minutes until the flesh is tender.
3. Shred the inner flesh with a fork to create long, spaghetti-like strands.
4. Sauté the chopped broccolini and minced garlic in olive oil for 4 minutes.
5. Combine the warm broccolini, ricotta, and half of the mozzarella in a bowl.
6. Fold the mixture back into the squash shells and mix with the strands.
7. Top each boat with the remaining mozzarella and a sprinkle of Italian seasoning.
8. Bake at 400°F (200°C) for 15 minutes until the cheese is bubbling.

Pro Tip: Squeeze the cooked squash flesh with a clean kitchen towel before mixing. This step removes excess moisture and prevents your lasagna from becoming watery.

Common Mistakes to Avoid

• Skipping the moisture squeeze: Spaghetti squash naturally holds a lot of water, which can dilute the creamy cheese sauce.
• Overcooking the squash initially: If you microwave it for too long, the strands will turn into mush instead of pasta-like ribbons.
• Using pre-shredded cheese: Pre-packaged cheese often contains anti-caking agents that prevent a perfectly smooth, stretchy melt.

Required Equipment

• Sharp Chef’s Knife: Helps you slice through the tough outer squash skin safely.
• Baking Sheet: Holds the squash boats securely while they bake to golden perfection.
• Sturdy Fork: Allows you to easily scrape the squash flesh into perfect noodles.

Caleb’s Recipe Tips

• Boost the heat by stirring a pinch of red pepper flakes into the ricotta.
• Add extra protein by mixing in cooked Italian sausage or shredded chicken.
• Save precious time by roasting the squash a day in advance.
• Enhance the aroma by stirring in freshly torn basil leaves just before serving.

Storage Instructions

You can store any leftover squash boats in an airtight container in the refrigerator. They will remain fresh and delicious for up to 4 days. However, freezing is not recommended because the squash can become watery upon thawing. To reheat, simply place a boat in the oven at 350°F (175°C) for 12 minutes. Alternatively, microwave on high for 2 minutes until the cheese melts completely.
