Ingredients you need
Zucchini is the go-to vegetable when you need to replace pasta with a healthier option. This lasagna is no exception. You will need to use long thin slices of zucchini as a replacement for the noodles.
I prefer to use a mandolin to slice the zucchini into a thin 3 mm (⅛ inch) sheet. However, a mandolin is not necessary. If you have a hard time slicing the zucchini into sheets, that's ok, the lasagna is just as tasty using thinly sliced zucchini circles.
You will need about one zucchini for every layer of lasagna. I made a 3 layer lasagna so I used 3 zucchini. The recipe will call for 3-4 zucchini to ensure you have enough. Start with 3 and if you need more slice up the fourth.
How to make sugar-free marinara
After you have sliced your zucchini, the next step is to make the marinara. Start by browning the ground beef and draining the grease.
Next add the can of sugar-free crushed tomatoes, or tomato puree, and the seasoning. Bring the sauce to a simmer and then remove it from the heat. The flavors of the sauce will continue to meld as the lasagna cooks in the slow cooker.
Cheat's Cheese Sauce
The cheat's cheese sauce is delicious and easy to make. In a separate bowl mix together the cheese, cream, eggs, salt, and pepper for the sauce.
I used a combination of shredded mozzarella and parmesan cheese for the cheese sauce. If you do not have a combination of the cheese you can use ½ cup parmesan cheese and ½ cup mozzarella cheese.
Your cheats cheese sauce will be somewhat liquid, this makes it easy to spread. Don't worry, it will firm up as it cooks.
How to cook lasagna in a slow cooker
Now that you have all the parts of the lasagna prepped it is time to assemble. Start by adding a little bit of marinara to the bottom of your slow cooker. This will keep the lasagna from sticking to the bottom.
Next, add a layer of zucchini on top of the marinara. Spread ⅓ of the cheese sauce over the zucchini, then cover it with ⅓ of the marinara. Add three layers to the lasagna then sprinkle the top with shredded cheese.
Cover the slow cooker and cook your lasagna on high for 2-3 hours or low for 4-5 hours. When the lasagna is done, let it cool for about 15 minutes before slicing and serving. The zucchini will release a lot of liquid, this can be carefully poured out and discarded if desired.
Oven cooking instructions
Your lasagna may also be cooked in the oven. Assemble your lasagna in a baking pan and cover with foil. Cook the lasagna for 40-45 minutes at 190 C/375 F, uncover the lasagna for the last 10 minutes to crisp the top.
