If you like recipes that are quick to prepare and flavor-packed, you will fall in love with this Gluten-Free Vegetarian Lasagna! It is the perfect way to incorporate fresh produce into a cheesy one-dish meal that your family is going to beg you to make time and again. This is one of my favorite gluten-free dinners, and I think you will love it too!
If you love cheesy recipes loaded with veggies, you will go wild for this meatless lasagna. It is pure comfort food and one of the best ways that I have found to sneak vegetables into the kid's diet.
I use Slow Cooker Marinara that I make ahead and keep in the freezer, but you could use jarred pasta sauce just as easily!
Combined with fresh gluten-free lasagna noodles, I've got a meal that is satisfying and delicious. (If you aren't gluten-free, you can substitute regular lasagna noodles!)
This gluten free lasagna recipe is one my family loved from the first bite!
Ingredients for Making Vegetarian Lasagna
- Zucchini: A mandoline or vegetable peeler makes easy work of slicing the zucchini thin.
- Spinach: I used fresh chopped spinach because that is what I had on hand. If you like frozen spinach works as well.
- Ricotta Cheese: You can use full-fat, part-skim, or vegan ricotta for a dairy-free option. Cottage cheese could also be used.
- Parmesan Cheese: Fresh grated is best. I don't recommend using the kind in the can. It lacks flavor and is loaded with preservatives. Make sure you are using rennet-free parmesan to keep this recipe vegetarian.
- Garlic: I prefer fresh minced garlic
- Fresh Herbs: I used a mixture of fresh herbs - basil and parsley are my favorites. If I happen to have it, oregano is also lovely in this vegetable lasagna recipe.
- Crushed Red Pepper: Red pepper flakes provide a subtle kick of heat. Feel free to leave it off if you are sensitive to heat.
- Marinara Sauce: I like to use homemade. If you are looking for a sugar-free marinara, this one is amazing.
- Mozzarella: I typically use part-skim mozzarella. If you have it, fresh mozzarella is nice on top.
- Lasagna Noodles: I use gluten-free frozen lasagna noodles because they are superior in taste. (I also love that you don't have to take the time to boil noodles.) If you use dried pasta, make sure you cook the noodles in salted water with a little olive oil before adding them to the lasagna. You can also use regular or no boil lasagna noodles to make this.
- Use Eggplant or Summer Squash in place of the zucchini. Carrot and bell pepper can also be added.
- Use a Creamy Tomato Sauce in place of traditional pasta sauce.
- Want to add some meat? You could easily add browned ground beef (or plant based crumbles) to the marinara before adding it to the veggie lasagna.
Make it Vegan
Vegan? Use vegan ricotta and Daiya shreds. Omit the egg. (No need to substitute anything in its place.).
If you don't want to make ricotta, Kite Hill has some fabulous options.
Make it Keto/ Low Carb
Make sure all of your cheeses are full fat, and the marinara is sugar-free. This Keto Marinara is fabulous. Omit the lasagna noodles and use zucchini in place of it.
To do this, use a mandolin, food processor, or very sharp knife to cut zucchini into ribbons.
Bake the ribbons in a 350-degree oven for 5 minutes, and then transfer to paper towels to absorb extra moisture. Use the prepared zucchini ribbons in place of the lasagna.
Making Ahead and Freezing
You can make this recipe up to one day ahead of time and cook it when you are ready to serve. Leftovers will keep for about three days.
You can freeze this recipe, but if you do, I recommend leaving the zucchini off. It just doesn't freeze well.
Frequently Asked Questions
What Vegetables are Good In Lasagna?
There are so many vegetables that work! You can saute red pepper, onions, and mushrooms and add any of them to your lasagna.
Zucchini, spinach, squash, and eggplant are other great options.
Do I Have to Cook Spinach Before Putting it in Lasagna?
Yes, you need to cook spinach before you put it in your lasagna.
When you cook spinach, it releases a tremendous amount of liquid. Putting raw spinach into a casserole will make it watery.
How Do I Keep Vegetables from Making Lasagna Watery?
The key is to make sure that you cook them before adding them to the lasagna! I recommend cooking all vegetables first.
Can I Use Oven Ready Lasagna Noodles?
Absolutely! They are a great option when you want to save time.
