How to make spaghetti squash lasagna: basic steps

This spaghetti squash lasagna is very easy to make! But it does take a bit of time. Why? Spaghetti squash can take up to 1 hour to roast. Yes, everyone’s favorite squash is a little high maintenance like that. But never fear! Once your squash is roasted, it’s terribly easy to put together. Here’s what to do:

Tips on how to cook spaghetti squash

The main task for this spaghetti squash lasagna is (no surprise!)…cooking the spaghetti squash. Here’s what to know about cooking this tough yellow squash:

Slice lengthwise to serve in “bowls”. Usually we slice the squash around the middle to get the longest noodles (see How to Cook Spaghetti Squash). But if you want to serve it in natural bowls, cit it lengthwise. Roasting is the best method. Roast your squash at 400 degrees until it’s tender, 40 to 55 minutes.Separate into noodles with a fork. Scrape out the cut sides with a fork: instant noodles! Allow to steam 5 minutes in a colander. This helps to remove excess liquid.

Alternative method: Instant Pot!

Want to speed up the cook time? You can cook your spaghetti squash in the Instant Pot, with one caveat: you’ll have to cook them one at a time. This spaghetti squash lasagna calls for 2 squash, but only 1 can fit in an Instant Pot at a time. The Instant Pot is significantly quicker: it takes only 13 minutes for the squash to cook. So even cooking two squash, it takes about half the time to pressure cook them. Score!

Bake it in the shells, or use a baking dish!

The fun part about this spaghetti squash lasagna is that you can bake it in the shells for beautiful presentation! But it’s not required. Here are a few notes about both:

Bake it in the shell: When you scoop out the spaghetti squash strands with a fork, keep the skin of the squash in tact. It forms a natural shell that you can use for baking it! Pros: it’s beautiful. Cons: it’s pre-portioned so you can’t choose how much you want, and it’s harder to serve to a crowd. Kids also seem to prefer the next option. Bake it in a 9 x 9 baking dish: Or, throw it into a 9 x 9 baking dish! It works just as well and takes a little less time to assemble. Pros: It’s easier to serve to a crowd, and seems more like “real” lasagna. Cons: It’s not nearly as stunning to look at.

Make ahead tips for spaghetti squash lasagna

Can you make ahead parts of this spaghetti squash lasagna for easy prep? Absolutely. Here are a few options to choose from:

Roast the squash in advance. Simply roast your squash in advance and refrigerate until you want to bake. Some liquid may accumulate while it refrigerates: just pour it off. While the oven preheats, layer the ingredients. Increase the final bake time a little since you’ll be baking the noodles from cold (or warm them in the microwave before assembling). Don’t assemble in advance. You might be tempted to assemble it then refrigerate, but we advise against this. Moisture can accumulate in the fridge, making it overly watery. Simply roast the squash in advance per above: you can layer it while the oven preheats and there’s no time lost!
