This cauliflower lasagna is the perfect blend of comfort food and nutrition! It’s brimming with layers of crisp-tender cauliflower lasagna noodles, rich ground beef and marinara, and gooey melted cheese. I told you this ground beef and cauliflower is comfort food at its finest! In the middle of the cold winter months, keto lasagna with cauliflower is a staple meal at our house.
And of course, even though traditional lasagnas take a lot of time to put together, this ground beef cauliflower casserole is easy to throw together. You can easily eyeball the quantities or be off on the timing, and it doesn’t matter if you estimate this or that. It will still turn out amazing. The ingredients are very simple and versatile, and you probably have most of them on hand. Just how I like it. 🙂
Cauliflower noodle lasagna is pretty flexible as well and you can make substitutions if you need to. Ground chicken or turkey works just fine instead of the beef. And if you have some other veggies on hand, they can stand in for the cauliflower. (For the record, in my opinion the cauliflower is the best, but you can swap it out if you must.)
This cauliflower lasagna recipe was originally published in February 2016 and was updated in October 2019.
What Is Keto Lasagna?
My keto lasagna takes all of the hearty and comforting flavors of traditional lasagna, but… it’s lasagna with cauliflower instead of noodles! Smart, right? Just like low carb keto chili, there’s no need to add additional starchy ingredients.
How To Make Cauliflower Lasagna
- Roast cauliflower. In order for our cauliflower noodles to taste great, we roast them BEFORE we assemble the beef and cauliflower casserole.
TIP: If you’re picturing cauliflower lasagna noodles as actual sheets, you can make those using this cauliflower pizza crust recipe. However, I think it’s unnecessary and roasted cauliflower is just as delicious!
- Make sauce. Cook some onions in a skillet, then add ground beef, garlic, marinara sauce, diced tomatoes, and half of the fresh basil. Season with salt and pepper and to taste.
- Assemble the cauliflower lasagna keto layers. Layer the cauliflower lasagna noodles in the bottom of a baking dish, top with tomato meat sauce and a layer of mozzarella cheese.
- Bake the roasted cauliflower lasagna. Bake for about 8-10 minutes, or until cheese bubbles.
- Garnish and serve. Top with thinly sliced basil ribbons and dig into your cauliflower beef casserole.
Is Lasagna Keto Friendly?
Most traditional lasagnas would NOT be considered keto-friendly as they are made with pasta noodles!
This version is made with cauliflower lasagna noodles, which means it’s grain-free, gluten-free, low carb, and keto. It still has all of the hearty and comfort of a traditional lasagna, but without the carbs.
How Many Carbs In Keto Lasagna with Cauliflower?
This keto lasagna with cauliflower has just 10 grams of net carbs per serving. Not bad for an entire meal!
Can You Make Ground Beef And Cauliflower Lasagna Noodles Ahead?
Yes, this ground beef and cauliflower lasagna can be made ahead of time! You can assemble the entire cauliflower noodle lasagna and bake right before serving, or prep some of the components separately so that the day-of, you can assemble and bake!
Roast the cauliflower pasta noodles and set aside and make the meat sauce. Refrigerate the components until you’re ready to assemble and then bake. It’s the perfect meal to make ahead!
How To Freeze Ground Beef Cauliflower Casserole
If you’re looking for low carb recipes with ground beef and cauliflower, AND a comfort meal that’s freezer friendly, you’ll want to save this low carb cauliflower casserole recipe. I’ve done it a few times and it works perfectly!
If you line the pan with foil before cooking, you can just freeze it right in the pan. Then, once it’s hardened, take it out by grabbing the foil edges. Wrap the top in more foil, and finish with plastic wrap.
The wrapping will avoid freezer burn, and the foil means you can throw it in the oven straight from the freezer – so convenient! Bake until it’s hot.
