Zucchini Lasagna Ingredients:

Donโ€™t let these ingredients scare you! This is a perfect combination of deliciousness that your family is going to love.

  • Olive Oil: I like to use Extra Virgin Olive Oil for itโ€™s flavor
  • Onion: Dice well,  you donโ€™t want large chunks of onion
  • Ground Beef: You could substitute ground turkey or ground chicken
  • Italian Sausage: This will give it the meal itโ€™s zest, if you like spicy for Hot Italian Sausage.
  • Crushed Tomatoes: Gives the recipe some texture with out the lumps
  • Tomato Sauce: Use low sodium to make it just heart healthier.
  • Tomato Paste: Gives richness and body without extra water.
  • Italian Seasoning: Donโ€™t skimp on the seasoning. Zucchini will take on the flavor
  • Sugar: Cuts the acidity in the tomato sauce so donโ€™t leave out.
  • Fresh Basil: Can use dried basil, just half as much.
  • Ricotta Cheese: Low fat works great if you want.
  • Parmesan: Make sure itโ€™s finely grated to make sure it melts well.
  • Egg: Adding an egg to the ricotta helps bind the cheese together and makes it rich and creamy.
  • Zucchini: Keep the zucchini the same length for even โ€œnoodlesโ€
  • Mozzarella Cheese: Buy pre-shredded mozzarella for faster prep.

How to Make Lasagna:

A rich zesty meat sauce is layered with a cheesy, creamy ricotta and thinly sliced zucchini that has been cooked to perfection. All of it is topped with ooey, gooey Parmesan and mozzarella cheese.

  1. Saute: In a large skillet saute the onions in olive oil till tender.
  2. Cook: To the onions add the beef and sausage and cook and crumble till brown and cooked through
  3. Add: Next stir in the crushed tomatoes, tomato sauce, tomato paste, Italian seasoning, sugar and basil. Let it simmer on low heat.
  4. Mix: In a separate bowl mix the ricotta cheese, parmesan and egg together thoroughly.
  5. Layer: In a 9ร—13 well oiled pan begin to layer the lasagna starting with 1 cup of the meat sauce then the zucchini, followed by the ricotta mix  and then some mozzarella cheese. Youโ€™ll repeat the layers and end with ooey gooey mozzarella on top.
  6. Bake: Cover with a aluminium foil and bake in 375 degree oven for 20 min. Then remove the foil and bake for an additional 20-25 minutes till heated through.
  7. Cool: Cool for at least 10 min to help the lasagna set before cutting.

Tips And Tricks for the BEST Zucchini Lasagna: 

Zucchini has a lot water in it naturally, use some of these tips to make sure your BEST Zucchini Lasagna isnโ€™t soggy.

  • Slice: To slice the zucchini thinly use a mandoline to get even 1/8โ€ณ slices.
  • Salt: Salt the zucchini to draw out the water and let it sit for 15 minutes, then pat thoroughly dry. If you use kosher salt itโ€™ll be easier to wipe it off.
  • Dry: Broil or grill your zucchini slices to dry out even further and give it a little extra flavor as well.
  • Thicken: Make sure your sauce is good and thick, if you need to thicken it take 1 Tablespoon of cornstarch mixed in 2 Tablespoons of cold water and stir into your sauce bringing it to a boil. Having a thick sauce will help absorb any water released from the zucchini.
  • Sneaky: If all else fails you can layer uncooked lasagna noodles on the very bottom of your pan. It wonโ€™t be completely gluten free but the uncooked noodles will soak up any liquid. You can always remove that bottom layer to make it low-carb before eating.

Variations and Storing Lasagna:

This Zucchini Lasagna is so adaptable and stores nicely for leftovers, if you have them.

  • Vegetables: Swap out the zucchini for eggplant or thinly sliced sweet potatoes. Add a layer of chopped vegetables, like cooked spinach, or saute peppers, mushrooms, or asparagus.
  • Protein:  You can use ground chuck, ground turkey or Italian chicken sausage instead of regular sausage.
  • Sauce: Make a whole new flavor by using Alfredo sauce instead of a tomato based sauce.
  • Store: Lasagna can be stored in the fridge for up to 5 days, cooked lasagna for up to 2 months.
