Recipe Notes
This delicious zucchini lasagna recipe uses a few simple techniques to make sure we emulate the classic dish! Check out these notes to see some special tips.
Ingredient Notes
Zucchini – This summer squash is packed with nutrients and antioxidants. It’s made mostly of water, which is why we have the first step of salting the zoodle. This helps remove excess water from the noodles so they don’t water down our casserole.
Ricotta – This fresh, fluffy cheese is a staple in lasagna. Layering this between the noodles and sauce is what gives lasagna the creamy, luscious mouthfeel that we adore and crave in the classic dish.
Low Carb Spaghetti Sauce – Did you know that many spaghetti sauces are LOADED with sugar? It’s true. So you want to double and triple-check that you have a low carb version of the sauce. We don’t need any sneaky carbs hiding in sauce!
Tools To Make
- Mandolin – This slicer helps protect your hands and keep food cuts consistent. Running your zucchini over this is going to give you even, consistent lasagna noodle-like slices. You can also use a knife, just try to keep your sices as consistent as possible.
- 9×13 pan – this large casserole dish is a classic size for lasagna. It’s wide enough to get full slices of zoodles across, and deep enough for nice thick slices of the completed dish.
Storing Tips
With a recipe this hefty, you’ll most definitely have leftovers. Luckily, this zucchini lasagna recipe stores really well. Put individual slices into airtight containers, or wrap them well with plastic wrap, and store them in the fridge. Reheat in the oven or toaster oven for the best results!
Can You Freeze This?
This zucchini lasagna recipe freezes beautifully, and, as a bonus, you can do that before or after it’s baked! When I want to freeze it unbaked, I wrap it in several layers of plastic wrap and aluminum. When it’s time to bake, I let it thaw in the fridge, then bake as planned.
When I bake it first, I wrap the leftovers in plastic wrap or freezer bags. Then, thaw them in the fridge, or reheat right away with a little added bake time.
Meal Prepping Tips
It can be exhausting thinking of healthy dinners, so this zucchini lasagna recipe is here to save the day! There are plenty of leftovers here to take care of all your low carb dinners.
Cut this gooey lasagna into portions, then store them in airtight containers in the fridge or freezer. Pull one out whenever you need a quick and healthy meal, and reheat it in the oven or toaster oven! Dinner is served!
Serving Suggestions
If you want to try something new, there are a few ways to change this dish up! Try layering individual zucchini strips and rolling them up. Place side by side in the pan for easy to plate zucchini lasagna rolls!
Or try turning these into easy and delicious zucchini lasagna boats – simply hollow out the zucchinis, saving the middle. Cook up the zucchini pieces with the meat and onions. Mix with the sauce and some ricotta, and load it into the zucchini boats, and bake!
Recipe Variations
I’m always swapping ingredients around when I cook, based on what we’re craving, or what I have in the fridge! Here are some tips if you need to make a substitution!
Can I Make Lasagna Noodles With Another Vegetable?
Yep! You can use sweet potatoes, eggplant, or pumpkins instead, as long as you slice them really thin. You could also try this hearty eggplant lasagna, or creamy cabbage lasagna for more veggie options.
What Kind Of Meat Can I Use?
You could use ground beef, sausage, or cooked chicken in this zucchini lasagna recipe, or use sliced prosciutto as layers instead of the zucchini! You may also enjoy this zesty zucchini lasagna with meat for a slightly different take.
Can I Add More Cheese?
Always. In fact, if you can, you probably should. I mean, who doesn’t love creamy, gooey, melty cheese?? You can add more of the mozzarella, parmesan, and ricotta that’s already in this recipe, or try this zucchini lasagna with cottage cheese!
Can I Skip The Meat?
You can totally leave the meat out of this dish to make it vegetarian. If you want to make this zucchini lasagna vegan, check out some cheese variations like cashew cheese or almond ricotta.
Can I Use Different Casserole Sizes?
You can! This low carb casseroles flexible, so make it in whatever size pan you have on hand.
I like to make this dish in a 9×13, however, you can use an oven-safe skillet or an 8×8 casserole as well. Using a smaller dish will mean your healthy casseroles slices will be a bit smaller, but each slice will be taller.
You’ll also need to adjust your bake time to ensure the zucchini lasagna is heated through.
Zucchini Lasagna
Ingredients
Noodles:
- 3 Large Zucchinis
- 1 Tablespoon Salt
Filling:
- 1 Pound Italian Sausage casing removed
- 1 Yellow Onion chopped finely
- 4 Garlic Cloves minced
- 2 - 24 Ounce Low Carb Spaghetti Sauce OR, no sugar added marinara
- 2 Teaspoons Oregano dried
- 1 Teaspoon Basil dried
- 1 Teaspoon Salt
- 1/2 Teaspoon Black Pepper
- 32 Ounces Ricotta Cheese
- 1 Large Egg
- 2 Cups Grated Parmesan Cheese divided
- 4 Cups Mozzarella Shredded divided
- 1 Cup Fresh Basil Chopped
Instructions
Noodles:
- Slice the zucchini lengthwise to form 1/4” thick "lasagna" noodles -- The best way to do this is with a mandolin. If you don't have a mandolin, use a sharp knife (a mandolin is strongly suggested to keep the noodles even!).
- Place sliced zucchini on a flat surface lined with paper towels.
- Sprinkle with half the salt and allow zucchini to sit for 10 minutes.
- Blot zucchini (firmly), flip, and repeat on the other side, using the rest of the salt to sweat this surface.
Filling:
- Meanwhile, preheat your oven to 350 F.
- Cook the meat in a large skillet until no pink is left. Break the meat up with the back of a wooden spoon as it cooks.
- Place cooked meat on a paper towel-lined plate and set aside.
- Carefully remove excess fat from skillet, and add vegetable oil.
- Once shimmering, add the onion and saute until soft, about 10 minutes.
- Add garlic and cook for about 1-2 minutes, or until the garlic is fragrant.
- Remove skillet from heat, and stir in the pasta sauce and meat. Set aside.
- In a large bowl, combine the oregano, basil, salt, pepper, ricotta, egg. Plus 1 cup of parmesan and 2 cups of mozzarella.
Layering:
- Spread 1/2 the meat sauce along the bottom of a 9x13 pan. Then a layer of zucchini. Then a layer of the ricotta combo.
- Repeat until you've used all the ingredients.
- Top lasagna with the remaining 1 cup of parmesan and 2 cups of mozzarella.
- Bake in the preheated oven for 45 minutes -- you'll know it's done when the top is golden brown and the dish is heated through.
- Allow lasagna to cool slightly before serving, and enjoy!
