Keto Lasagna

This keto lasagna is comforting, delicious, and tastes like the real thing! Layers of low-carb lasagna noodles, meat sauce, ricotta cheese, and plenty of mozzarella cheese, it’s keto comfort food at its finest!
I’ve been eating lasagna for as long as I can remember, and I see no reason why being keto should change that. If you’ve tried my zucchini lasagna, then surely you’d agree.
My recipe is similar to a traditional lasagna. I swap the regular lasagna noodles for a keto alternative: a mixture of cheese and egg that forms a sturdy, pasta-like texture. I did test out a store-bought “miracle noodle” style lasagna sheets, which were convenient but tasted NOTHING like noodles.
The results in my homemade version speak for themselves: thick, savory lasagna sheets stacked between a rich filling of beef, red sauce, and even more melted cheese. Altogether, it’s one of my favorite keto dinner ideas that’s always a hit–just ask my whole family!

Recipe highlights
- Incredible flavors. We’re talking layer upon layer of cheese, savory red sauce, and juicy ground beef. What could be better than that?
- Quick and easy. Yes, you need to make the lasagna sheets from scratch, but even then, the total cooking time is less than that of a traditional lasagna.
- Deceptively low-carb. For how decadent this lasagna is, you’d never believe it has only 2 grams of net carbs per serving.
Enjoy it on its own or pair it with some keto cheese bread or keto garlic bread for a well-rounded meal.
Key Ingredients
Here’s what goes into my keto lasagne recipe, along with kitchen notes. The complete list with measurements is in the recipe card below.
For the keto lasagna noodles
- Cream cheese. I recommend using cream cheese from a block over a tub, as it has a thicker texture and no added water.
- Mozzarella cheese. Mozzarella has a mild flavor and stretches beautifully, making it the perfect cheese for the noodles. Do not use cheddar or any other cheese, as they are prone to forming a film on the exterior.
- Parmesan cheese. Use finely grated Parmesan or fresh Parmesan. Some supermarkets sell a powdered version, which won’t work well and will leave the noodles gritty.
- Eggs, room temperature eggs. I recently tested this with an egg substitute, but unfortunately, it didn’t turn out at all.
For the filling.
- Onion and garlic. Necessary additions to any good bolognese sauce or marinara recipe.
- Ground beef. I used lean ground beef, but any cut of ground beef works.
- Marinara sauce. Use a marinara sauce with no added sugar. You can also use my keto pizza sauce or keto spaghetti sauce.
- Salt and pepper. to taste.
- Ricotta cheese- To layer the lasagna and give it creaminess. It is like a mock bechamel. Please opt for full-fat ricotta, as the lower-fat versions contain added water and thickeners that also increase the carbs.
- Mozzarella cheese. What is a lasagna without mozzarella?
How to make a keto lasagna
Step 1- Prepare the lasagna noodles. Start by adding the cream cheese, mozzarella, and parmesan, then microwave in 30-second spurts until the mozzarella has mostly melted. Whisk in the eggs until a thick and creamy batter remains.
Step 2- Bake the noodles. Next, bake the lasagna for 15 minutes, until it’s just golden around the edges.
Step 3- Make the meat sauce. Now, add the onions and garlic to a pan and saute for 5 minutes. Add the ground beef and cook until no longer pink. Add the marinara sauce, salt, and pepper, and continue pan-frying for a further 5 minutes.
Step 4- Assemble and cook. Finally, add tin foil to a pan, leaving half an inch overhanging on each side. Slice the lasagna sheet into six even pieces. Place two pieces on the bottom of the pan, followed by a third of the ricotta, a third of the meat sauce, and a third of the mozzarella. Repeat until all the noodles are cooked. Bake in the oven for 30-35 minutes, until golden brown on top. Slice, then serve.
Arman’s recipe tips
- Let the noodles cool. Make sure the lasagna noodles have cooled for a few minutes before layering. Otherwise, you risk melting the ricotta and compromising the lasagna’s structure. I find 3 to 4 minutes to be plenty.
- Use freshly grated cheese. Admittedly, I usually don’t heed this advice, but grating a block of fresh cheese makes for a better overall texture.
- Save time. I find making the lasagna noodles in advance saves a ton of time when I go to assemble the lasagna.
- Add some heat. If you’re a spice fiend, add a few dashes of red pepper flakes to the meat sauce.
- Amp up the seasonings. Depending on how flavorful your red sauce is, it might need a little flavor boost. I usually stir in some salt, black pepper, and oregano or, at the very least, garnish the lasagna with fresh basil.
How to store leftovers
To store: Leftovers should be refrigerated in a sealed container for up to 1 week.
To freeze: Place individual portions of lasagna in airtight containers and store in the freezer for up to 6 months. Let them thaw overnight in the refrigerator, or add more reheating time.
To reheat: Reheat leftover lasagna in the microwave or oven at 350F until warm.
Frequently asked questions
There are just 2 grams of net carbs in each serving of lasagna. This is made as written, including the low-carb lasagna noodles.
As mentioned earlier, I tested these with keto-friendly lasagna noodles, but I wasn’t a fan. It had no flavor and also tasted like you were chewing on plastic (sorry). Instead, I suggest replacing the noodles with low carb vegetables, like zucchini or eggplant. Summer squash is also a good option.
If you’d like to make this lasagna in advance, it’s easy! Just prep the layers as instructed, but allow them to cool completely before assembling. Then, assemble the lasagna, cover it in plastic wrap, and store it in the fridge for 1-2 days or in the freezer for up to 3 months. If refrigerated, add an extra 10 minutes to the baking time. If frozen, let it thaw overnight in the fridge before baking.

This is not only the best keto dish I’ve ever made, but one of the best dishes (period) that I’ve ever made. These homemade low carb noodles are soooo much better than using egg wraps, hearts of palm, etc. My husband and super picky kids loved this as well and ate it up within a few days. I’m already writing up my grocery list to make it again. The only addition I made was that I added a bag of steamed chopped spinach. Thank you so much for sharing! This will definitely be a staple dish in my newly started keto lifestyle.
Sorry, found the info!
We all loved this. The only problem I run into when making low carb pasta or bread, where melted cheese needs to be whisked into a smooth substance, is that it never works for me.. As soon as the cold eggs hit the cheese, the cheese clumps up. Any solutions for this? Otheriwse, great recipe! Thank you for sharing.
Hi Liz- it comes down to the cheese being too cool. You can combat this by bringing the eggs to room temperature and whisking them in while the cheese is still warm (not sizzling/hot). 🙂
Absolutely Amazing. Thank you for this recipe.
If I could give this 10 stars I would! I’ve been craving lasagna since starting Keto and this exceeded all expectations! I liked it better than regular lasagna. I substituted mild Italian sausage and cottage cheese instead of ground beef and ricotta. So delicious 😋
I have made this a few times and it is a huge success with everyone
Thank you for the inspiration
Wonderful recipe finally getting to have lasagna again
This recipe is thebomb.com. It rivals regular lasagna and totally scratches the pasta itch! 🤤
I made this.. Big hit everyone loved it. They didnt know it was low carb!!!!
This came out amazing! Was so surprised these keto noodles could be equivalent to a pasta noodle. They are better than pasta!! Flavorful, cuts nicely into portions. I always add fresh herbs from my garden to spruce up meat sauce so that is the only thing I did differently. A total winner! My family loved it!!
Have you used this recipe for other food, such as ravioli or linguini? Thank you very much!
I made this in a 9 X 5 pan without the tin foil and it’s perfect. It’s one of my top favourite keto recipes, and I’m not easy to please. Just one question about serving size. You gave the macro breakdown for one serving, but you didn’t say how big a serving size is. Is it based on 6 servings in the pan?
I loved this. I wasn’t sure what to expect with all the cheese, but it was delicious. I’ll be making it again soon.
It states it makes 8 servings in an 8×8 pan, so just cut in 8 equal pieces and that would be a serving.
I have been missing Italian food for two years, and this was fantastic! I wouldn’t have believed it was low carb if I hadn’t made it myself. I’m making two this weekend so the freezer will be well stocked!
THANK YOU!!
I made two lasagnas, one with traditional noodles and one with your Keto noodles. My husband and neighbors agreed that the Keto noodles were superior to the traditional noodles. This is the first time I have had lasagna in over 5 years. Thank you so much!
