Low-Carb Butternut Squash Lasagna

Low-Carb Butternut Squash LasagnaPin recipeFollow us 53.2k

Comfort food doesn't get more classic than lasagne. My low-carb and gluten-free take on this Italian classic features delicious layers of thinly sliced butternut squash, homemade marinara sauce, ground beef, creamy herb-infused ricotta, melty mozzarella and crispy Parmesan.

I used pre-cut butternut squash from a local grocery store. If you can get pre-cut squash, it will save you a ton of time but if not, simply use a mandolin.

Although this grain-free lasagna is not ultra low in carbs, it can be included on a keto diet as long as you stay within your macros. It's high in nutrients and ideal for intermittent fasting when you eat one or two meals per day.

Ingredients (makes 6 servings)


  1. Prepare the Marinara Sauce by following this recipe. Preheat the oven to 200 C/ 400 F. Low-Carb Butternut Squash Lasagna
  2. I used pre-cut butternut squash lasagne sheets. If you can't get pre-cut slices, simply peel the butternut squash and remove the seeds. Then use a mandolin to slice it thinly (about ⅛ inch or ¼ cm). Low-Carb Butternut Squash Lasagna
  3. Grease a large pan with ghee and add the ground beef. Cook for 5-7 minutes while stirring, or until opaque. Add half of the marinara sauce and oregano. Season with half of the salt and pepper. Low-Carb Butternut Squash Lasagna
  4. Prepare the ricotta layer. Combine the ricotta, eggs, chopped parsley and basil. Season with the remaining salt and pepper. Low-Carb Butternut Squash Lasagna
  5. Spread the remaining marinara sauce on the bottom of a large casserole dish. I used a 26 x 18 x 6.5 cm (10 x 7 x 2.5 inch) casserole dish. Add the first layer of butternut squash slices. You will use a total of 3 butternut squash layers. Low-Carb Butternut Squash Lasagna

I changed the way I ate in 2011, when I was diagnosed with Hashimoto’s, an autoimmune disease that affects the thyroid. I had no energy, and I found it more and more difficult to maintain a healthy weight.

That’s when I decided to quit sugar, grains, and processed foods, and to start following a whole-foods-based ketogenic approach to food.

I would love to find these pre-cut lasagna sheets. Anyone in the US know where they might be sold? It sounds so much easier than peeling and slicing the squash. Thanks in advance.


Oh my dear, I made this yesterday and we finished the whole lot!!! It is simply delicious, easy to make and fingerlicking good.
I found your website recently and truly happy with your recipes. Enough inspiration for the coming time!
Have a great day,


Yvonne, thank you for your kind words!


Sorry..what is a "pack" of ricotta.  It says 500 grams or 1.1 ounces...do you mean pounds?


Yes that is correct, it was meant to be in "pounds" - I'll fix it now. Thanks!


Haven't tried recipes yet but certainly sound great. I would like to know if we can eat lentils?


Thank you Lynn! I'm afraid lentils are not on the "regular" low-carb/keto food list: Complete Keto Diet Food List: What to Eat and Avoid
This doesn't mean that all legumes are a no-no (at least not for everyone): Peanuts on a Ketogenic Diet: Eat or Avoid?
