Whenever you have an hour to prepare a filling meal for the whole family, give this pasta recipe a go! I’m one of those pasta lovers who simply can’t give up lasagna – even on a low-carb lifestyle. That’s why I immediately came up with this recipe for you.

What Makes This Lasagna Dish Keto?


It’s the pasta that carries a lot of carbs. That is why I was delighted to find out that there are keto-friendly noodles and pastas available in the market. There are now pasta alternatives for the traditional version. I’ll be using keto-friendly fettuccine for this recipe. You may use and keto pasta available in your local grocery.

Aside from using low-carb fettuccine, I was extra careful in choosing the rest of the ingredients – from the meat sauce to the topping. You can check the ingredients list below. Finally, I avoided white sugar and sweet Italian sausage which a lot of lasagna recipes use.

Cooking Equipment Needed

  • Lasagna spatula
  • Knife
  • Baking dish
  • Colander (for the fettuccine)
  • Grater

Frequently Asked Questions

How do I properly store cooked keto lasagna?

Store cooked lasagna in an airtight container or freezer bag. Then freeze it. A temperature of 0°F will keep it safe and fresh for up to 2 months in the freezer.

How do I reheat keto lasagna?

Transfer the lasagna to a baking dish, cover with aluminum foil, and bake it at 330 °F. You can also microwave it.

What should the first layer of my lasagna be?

One mistake that people make with lasagna is placing the pasta as the first layer on the dish. Doing this will cause the pasta to stick on the baking dish. So instead, use the meat sauce as the first layer.

Tips & Tricks

  • If you happen to be a vegetarian, use a meat substitute for ground beef. Cremini and shiitake mushrooms make your dish meatier.
  • Store-bought tomato sauce is more convenient. However, a lot of options carry plenty of carbs and sugar. Choose the option that has the lowest possible carbs. If you want, you can make your own version!
  • While baking keto lasagna in the oven, cover it with foil to avoid dryness. Only remove the foil when it’s almost done.

Keto Lasagna is a baking recipe

Rated 5.0 out of 5

The recipe for Keto Lasagna is a baking recipe and baking with ghee is always a safer option than olive oil. I have tried the recipe with ghee instead of olive oil. Ghee’s high smoke point is an advantage for baking with ghee. I use grass-fed ghee in place of olive oil for tasty and safe baking.

You obviously made the lasagna while documenting the steps for the instructions before coming up with the FAQs. But in the FAQ you tell us to make the first layer meat sauce so the noodles don’t stick to the dish. Yet in the Assembly instructions you tell us to add half the noodles to the dish and then cover them with the meat sauce. Reread & correct before posting, please.

Hi there, thanks for feedback – we appreciate it! In response, we’ve updated the recipe steps to show that we should start with the meat sauce as the first layer (bottom of the dish). Hope this hasn’t caused a lot of inconvenience on your end. Have a great day.
