In this post, we’ll walk through how to make spaghetti squash lasagna step by step, plus tips for avoiding a watery result.
 
Let’s dive in.
 

How to Make Spaghetti Squash Lasagna (Step by Step)

Making spaghetti squash lasagna comes down to three main phases: roasting the squash, prepping the filling, and layering everything for the oven.
 
Here’s how to make spaghetti squash lasagna that turns out perfectly every time.
 

1. Roast the Spaghetti Squash First

Start by preheating your oven to 400°F.
 
Slice the spaghetti squash in half lengthwise, scoop out the seeds, and drizzle the flesh with olive oil, salt, and pepper.
 
Place the halves cut-side down on a baking sheet and roast for about 35 to 40 minutes until the flesh is fork-tender.
 
Once it cools, use a fork to scrape out the strands, which is the “spaghetti” that makes this spaghetti squash lasagna possible.
 

2. Drain the Squash to Avoid a Watery Lasagna

Spaghetti squash holds a lot of moisture, and that’s the number one reason spaghetti squash lasagna turns out soupy.
 
After scraping the strands, place them in a colander or wrap them in a clean kitchen towel and press gently to remove excess liquid.
 
Let the squash sit for 10 to 15 minutes, then squeeze again.
 
This one step makes a huge difference in how to make spaghetti squash lasagna that slices cleanly instead of pooling water.
 

3. Prepare the Cheese Filling

In a bowl, combine ricotta cheese, one egg, grated Parmesan, minced garlic, chopped parsley, salt, and pepper.
 
The egg helps bind the ricotta so your spaghetti squash lasagna holds its shape when you cut into it.
 
You can also add a handful of shredded mozzarella into the mix for extra creaminess.
 

4. Layer Like a Classic Lasagna

Spread a thin layer of marinara sauce on the bottom of a baking dish.
 
Add half the spaghetti squash strands as your first “noodle” layer, then top with half the ricotta mixture, more sauce, and a sprinkle of mozzarella.
 
Repeat with the remaining squash, ricotta, sauce, and a generous final layer of mozzarella and Parmesan on top.
 
This layering method is exactly how to make spaghetti squash lasagna that looks and tastes like the real deal.
 

5. Bake Until Bubbly and Golden

Bake at 375°F for 25 to 30 minutes until the cheese is melted and the edges are bubbling.
 
For a golden top, broil for the last 2 to 3 minutes, keeping a close eye so it doesn’t burn.
 
Let the spaghetti squash lasagna rest for 10 minutes before slicing, which helps it set up beautifully.
 

Tips for the Best Spaghetti Squash Lasagna

A few smart tweaks will take your spaghetti squash lasagna from good to unforgettable.
 

1. Use a Thick, Low-Sugar Marinara

A watery sauce will ruin your spaghetti squash lasagna fast.
 
Choose a thick marinara or simmer your sauce down for a few minutes to concentrate the flavor.
 

2. Add Protein If You Like

Cooked ground beef, Italian sausage, or shredded chicken all work great in spaghetti squash lasagna.
 
Just brown the meat first and drain the fat so the dish doesn’t get greasy.
 

3. Don’t Skip the Resting Time

Resting lets the layers firm up, which is key when you’re learning how to make spaghetti squash lasagna that slices neatly.
 

4. Make It Ahead for Busy Nights

You can assemble spaghetti squash lasagna a day ahead and refrigerate it covered.
 
Add a few extra minutes to the bake time if it goes into the oven cold.
