How long do you bake Zucchini Lasagna?

The general rule is that you should bake the zucchini lasagna for about one hour. However, if you are making a larger batch for a huge family, you need to make sure that you are baking it for a longer time.

You will know that the lasagna is cooked when the sauce on top is getting darker. However, be careful about cooking it for too long as it might burn at the bottom of the pan.

How to prepare the zucchini before using it in the lasagna?

You should slice the zucchini in 1/8-inch slices. But, because they are watery, it is best to grill or roast them first. Using your grilling pan is a great option. Grilling it on both ends will ensure that most moisture will get removed.

After grilling, you should put the zucchini slices on a paper towel to remove as much moisture as possible before you start using it to build your lasagna. If you skip this step, your lasagna will be a bit watery, but it will still taste good.

How do you roast zucchini for lasagna?

  • Slice the zucchini in about 1/8-inch slices, then splash with some olive oil, salt and pepper.
  • Arrange the zucchini uniformly in a large baking pan, and put in the oven at 425 degrees F.
  • Roast for about 12-14 minutes, or until tender.

Can you make a healthier zucchini lasagna as well?

Yes, it is possible to make a healthier zucchini lasagna. You should use leaner ground beef, or substitute the beef with chicken or other leaner meats. For vegetarian version,  I recommend using tofu, beans, or some extra veggies. I usually go for a mix of bell peppers, mushroom and spinach.

Does zucchini lasagna freeze well?

Yes, the zucchini lasagna freezes really well. You can prepare the lasagna in advance and freeze it. Then, you should just put it back into the oven to defrost and to make it warm again.

The secret here is that you should prepare the meal, and make sure that you are freezing it in a container that will be oven safe. Otherwise, you might have a problem with defrosting and heating it up again. Best to freeze it up to three months.
