This flavorful keto lasagna proves that you don't need starches to enjoy traditional Italian flavors. With tasty layers of spinach and cream cheese, seasoned ground beef, and mozzarella, it's a big hit each time I make it!

This lasagna is so delicious. Warm layers of seasoned spinach, ground beef, and melted cheese - you won't miss the noodles! Over my 14 years of eating a low-carb diet, I have learned that quite often, the flavors we associate with grains are, in fact, the flavors of the fillings and toppings. This is true for pizza (like this cauliflower pizza crust), and it's also true for keto lasagna and zucchini lasagna.
Ingredients

See the recipe card for exact measurements. Here are my comments on some of the ingredients.
- Frozen chopped spinach: I use frozen chopped spinach because I always have it in the freezer, which is very convenient.
- Ground beef: I use lean ground beef (85% lean and 15% fat). I don't recommend going any leaner. While it won't be bad, it won't be as good as meat with a higher fat content, and the lasagna could be a bit dry.
- Onion and garlic: It's fine to use jarred minced garlic, although freshly minced tastes better.
- Marinara sauce: It's best to use a sugar-free brand such as Rao's.
- Cream cheese: I use full-fat cream cheese.
- Cheese: I use shredded mozzarella.
Variations
- Chop ¼ cup of fresh basil and mix it into the cream cheese.
- Dried herbs are good too - you can mix ½ teaspoon of any dried herb (oregano and basil are especially good) into the cream cheese.
- Like your food spicy? Add ¼ teaspoon red pepper flakes to the cream cheese.
- You can replace the mozzarella with another melty cheese, such as provolone.
- Sprinkle a tablespoon of grated Parmesan cheese on top of the mozzarella for added flavor.
Instructions
The detailed instructions and step-by-step photos are included in the recipe card. Here's a quick overview.
Make the beef layer: Cook the beef and onion in olive oil. Drain the beef mixture and return it to the skillet. Add the garlic and mix in the marinara sauce. Turn the heat off.

Make the cream cheese layer: Soften the cream cheese in the microwave. Add the egg, black pepper, and salt. With a spatula, add the drained spinach and mix to blend everything together.

To assemble the lasagna, spread the spinach mixture evenly on the bottom of a greased baking dish. Top it with the meat mixture, and sprinkle the mozzarella on top. Bake the lasagna until the cheese is bubbly and lightly browned, about 30 minutes. Let it stand for ten minutes before cutting and serving.

I really missed lasagna when I went on a low carb diet. Well, this keto lasagna was as delicious as any I have ever had. I did not miss the noodles at all. I sprinkled a little parmesan cheese on top and it was even better.

Recipe Tips
- It's important to remove as much liquid as possible from the spinach to prevent watery lasagna. You should drain it thoroughly by placing it in a colander and pressing on it repeatedly with the back of a large spoon.
- You can double this recipe and bake the lasagna in a 9X13-inch baking dish.
- To use fresh spinach: A 10-ounce package of frozen spinach equals about one pound of fresh spinach. Steam the spinach and drain it well, the same way you would drain frozen spinach. Chop it, and proceed with the recipe.
- Storage: You can keep the leftovers in an airtight container in the fridge for 3-4 days. Reheat them gently in the microwave at 50% power. You can also cut the lasagna into individual portions and freeze them in freezer bags for up to three months.
Serving Suggestions
With its rich layers of meat, dairy, and veggies, keto lasagna is a complete meal, so it doesn't really need any sides. However, you can serve it with a side dish if you wish. When I do, I like to serve it with a simple salad that I can make ahead of time, such as one of these:

Ingredients
- 10 ounces frozen chopped spinach
- 1 tablespoon olive oil - plus more for the pan
- 1 pound lean ground beef - 85/15
- 1 small onion - chopped; 4 ounces
- 1 teaspoon Diamond Crystal kosher salt - divided, or ½ teaspoon of any other salt, including Morton kosher salt
- 1 tablespoon fresh garlic - minced
- ½ cup marinara sauce
- 8 ounces cream cheese
- 1 large egg
- ¼ teaspoon black pepper
- ¾ cup mozzarella cheese - part-skim, shredded; 3 ounces
Instructions
- Preheat the oven to 350°F. Lightly grease a square 8-inch baking dish (or any other 2-quart baking dish).
- Defrost the spinach in the microwave according to the package directions. Drain thoroughly by transferring the thawed spinach to a colander and pressing on it repeatedly with the back of a large spoon to extract as much liquid as possible. Set aside.
- Heat the olive oil in a large skillet over medium-high heat for about 3 minutes. Add the beef, onion, and ½ teaspoon of kosher salt. Cook, using a wooden spoon to stir and break up the ground beef into small chunks, until the onion is soft and the meat is browned, 5-7 minutes.
- Drain the beef mixture and return it to the skillet. Add the garlic and cook, stirring, for 30 seconds, then mix in the marinara sauce. Turn the heat off.
- Place the cream cheese in a medium microwave-safe bowl and heat it for 40 seconds to soften. With a fork, stir it until smooth and creamy. Add the egg, black pepper, and remaining ½ teaspoon of kosher salt. Keep stirring the mixture until very smooth. With a spatula, add the drained spinach and mix to blend everything together. Mix well.
- To assemble the lasagna, spread the spinach mixture evenly on the bottom of the prepared baking dish. Top it with the meat mixture, and sprinkle the mozzarella on top.
- Bake the lasagna until the cheese is bubbly and lightly browned, about 30 minutes.
- Let the lasagna stand for ten minutes before cutting and serving.

- I don't recommend using extra-lean ground beef. While it won't be bad, it won't be as good as meat with a higher fat content, and the lasagna will come out a bit dry.

- To use fresh spinach: a 10-ounce package of frozen spinach equals about one pound of fresh spinach. Steam the spinach and drain it well, the same way you would drain frozen spinach. Chop it, and proceed with the recipe.
- You can keep the leftovers in a sealed container in the fridge for 3-4 days. Reheat them gently in the microwave at 50% power. You can also cut the cooled lasagna into individual portions and freeze them in freezer bags for up to three months.

Judy says
Can you use canned chopped spinach?
Vered DeLeeuw says
Hi Judy,
I don't recommend that. Canned spinach is mushy and has a metallic aftertaste.
Nicole says
HI,
I am allergic to eggs. Do you think I can remove the egg and it will still be good? 🙂
Vered DeLeeuw says
Hi Nicole,
I only tested this recipe with an egg, so I'm not sure, but I think it's worth a try. I suggest mixing two tablespoons of heavy cream into the cream cheese instead of the egg. The lasagna might not set as well, and it's possible you would need to scoop it out instead of cutting it, but it should still taste good.
Susie Knott says
Excellent! Quick and easy to make. Tastes excellent. Traditional lasagna noddles aren’t even missed!

This recipe looks absolutely fabulous but, due to my very high cholesterol levels coupled with a severe allergy to cholesterol meds, I need recipe's cholesterol level. Would you please be kind enough to provide? Thank you very much!
Vered DeLeeuw says
Hi Dianne,
According to the nutrition calculation tool used on this website, a serving of this recipe (a sixth of the entire lasagna) has about 130 mg of cholesterol.
However, I would encourage you to verify this information independently. Here's a website where you can calculate the nutrition info for recipes . You can copy and paste the list of ingredients and make any changes needed to ensure the calculation uses the correct ingredients and amounts.

Terry Batson says
I used fresh spinach...delicious! This will be a staple in our house!
Vered DeLeeuw says
Yay! So glad you liked it, Terry!
Connie says
Can I use fresh spinach in this recipe?
Vered DeLeeuw says
Sorry, Connie - I only tested this recipe with frozen spinach.
Brittany says
I’m not a huge fan of cream cheese. But I heard cottage cheese can be used in place of ricotta cheese. Do you think cottage cheese could be a fair replacement in this recipe?
Vered DeLeeuw says
I don't think cottage cheese would work in this recipe.
Kathy Lehnick says
Quick question, could you use thinly sliced, lengthwise zucchini or eggplant to replace the noodles?
Vered DeLeeuw says
There are no noodles in this recipe. I do have a recipe for zucchini lasagna that you could try. If you use zucchini or eggplant, it's important to grill them before using them in the lasagna to avoid watery lasagna.
