INGREDIENTS IN KETO LASAGNA

Zucchini - I used three medium-sized zucchinis for this recipe. It's best to slice them with a mandolin so that they are very thin and even. These slices make our keto lasagna "noodles".

Ground Beef - A hearty meat sauce starts with beef. You could also consider using half Italian sausage and half ground beef to add more flavor.

Onion and Garlic - Sauteed and added to the sauce, these aromatic veggies give the dish depth.

Keto Marinara Sauce - Pick up your favorite keto-friendly sauce at the store. Be sure to check for added sugars - many pasta sauces are not keto-friendly. You can also make your own Keto Tomato Sauce.

Herbs - Dried basil and oregano flavor the sauce, while dried parsley adds brightness to the ricotta cheese filling.

Seasoning - Simple salt and pepper ensure that your sauce is perfect.

Ricotta Cheese - Choose whole milk ricotta to keep this recipe low carb.

Parmesan - Grated parmesan cheese is classic and flavorful.

Mozzarella - This melty cheese creates the most amazing top layer to this casserole.

Egg - a whole egg is mixed with ricotta to add stability to the lasagna. This is what keeps the cheese from running out of the lasagna after you slice it.

HOW TO MAKE KETO LASAGNA

Start by preheating the oven to 375°F and spraying a 9x13 inch baking dish with cooking spray.

Use a mandolin to carefully slice the zucchini into ⅛-inch thick slices. Lay the slices onto a flat kitchen surface and sprinkle them salt to draw out some of the moisture. Wait 15 minutes, then pat the zucchini dry with a towel.
Make the sauce. Brown the beef, onion, and garlic in a large saucepan breaking the meat apart as it cooks, cooking until fully browned and cooked through.
Add the marinara sauce, basil, oregano, salt, and pepper and stir until combined. Bring the sauce to a boil then reduce the heat and simmer for 5 minutes, stirring occasionally.
Make the filling. Combine the whisked egg, ricotta cheese, parmesan cheese, and dried parsley.
Layer the lasagna. Spread a little sauce on the bottom of the baking dish first.
Add a layer of zucchini noodles over the sauce
Spread ⅓ of the ricotta mixture over the zucchini, followed by ⅓ of the meat sauce. Sprinkle with a half cup of mozzarella cheese.
Repeat the layers (zucchini, ricotta, sauce, mozzarella) two more times.

Finish the lasagna by baking it in the oven as directed in the recipe card below.

ARE ZUCCHINI NOODLES KETO?

Zucchini sliced into thin sheets is the perfect keto replacement for lasagna noodles. Spiralized zucchini also makes an excellent keto pasta substitute.

WHAT ELSE CAN I USE INSTEAD OF LASAGNA NOODLES?

Low carb recipe creators are some of the most creative people out there! There are keto lasagna recipes that use deli turkey instead of noodles, and some recipes that use a homemade low carb cheese noodle to do the job instead.

There are also products available, such as hearts of palm lasagna noodles and cauliflower lasagna noodles.

We like this keto lasagna with zucchini noodles the best because it's easy to make, doesn't require any special ingredients, and the zucchini adds great flavor and nutrition to the dish too.

IS ZUCCHINI THE SAME AS COURGETTE?

Yes it is! Courgette is the word used in the UK to describe what folks in the US call zucchini.

HOW CAN I KEEP ZUCCHINI LASAGNA FROM BEING WATERY?

Zucchini is delicious as a stand in for lasagna noodles, but it does have one very serious flaw: Zucchini is a very watery vegetable!

If not treated properly, you could end up with a watery, soupy mess. The mess will be tasty, but not very easy to eat with a fork.

My best tip for zucchini lasagna is that you NEED to salt the sliced zucchini and dry it off before layering the dish.

Be sure to generously salt the zucchini slices and let them sit like that for at least 15 minutes. At that point you can take a kitchen towel or paper towels and soak up any liquid that the salt pulled out of the zucchini.

While tomato sauce will have some natural sugar because it's made with tomatoes, it shouldn't have any added sugars.

Rao's Marinara sauce is a popular choice among low-carb cooks. It has 5 net carbs per serving.

You can be extra sure that your marinara sauce is keto friendly by making it yourself!

It's important to let the lasagna rest before slicing it. The cheese mixture needs to cool a bit so that your slices stay together.
The nutrition facts here are a guide. Your lasagna may have more or less net carbs per serving, depending on the ingredients that you use.
To avoid unnecessary carbs in shredded cheese, buy a block of cheese and shred it yourself rather than using bagged cheese.
