What inspired me to make this Low Carb Lasagna?

Lasagna is Grumpy’s absolute FAVORITE pasta casserole. Who can blame him for this? It has all the factors of pure comfort food. The moment you put one bite in your mouth, you will feel better! Now that we are sticking to the Keto diet, it is sad for him that his favorite meal became off limits. As a result, I had to find a way to make it low carb for him so he could still enjoy it.

A few months back I had received a box of low carb palmini spaghetti noodles in a subscription box. They intrigued me because of how they came packaged; shelf stable and vacuum packed. I wasn’t quite so sure it was a product we would eat. But, I gave them a try and found out they were an excellent substitute for regular spaghetti. And, when I found out they also made a lasagna shape noodle, I knew we had to try it!

What is keto pasta?

Keto pasta is a low carb option to replace the regular flour made noodle in a recipe. There are many versions of keto pasta. We love the palmini noodle because it is quick, convenient, and has great macros. A photo of a box of the Natural Heaven Veggie noodle substitute

What if I don’t want to use Palmini noodles?

That’s ok! You can make your own noodles. Eggplant or Zucchini make a good substitute if you want to stick to a vegetable. However, you can also make a fathead pizza crust, bake it, then cut it into noodle shape! If you need a recipe for pizza crust, check out my Wine Braised Short Rib Keto Pizza and just make the recipe for the crust!

What do you use as a marinara for low-carb lasagna?

There are several low-carb marinara options that you can buy ready made. Rao’s Homemade is an excellent choice. However, you can also make your own simple red sauce. If you buy a marinara sauce in the store, be sure to read the nutrition label. Sauces can be tricky and have hidden added sugars.

Can I substitute Cottage Cheese for Ricotta?

Plain and simple. No. I don’t recommend it. Sure, you can substitute it, but Cottage Cheese is not keto friendly like ricotta. Besides. Ricotta is better. And, I don’t suggest messing with a good thing!Picture of all the cheese filling ingredients. Ricotta, mozzarella, parmesan, egg, and parsley

I always use my Pyrex 1.5 quart loaf pan to bake my lasagna in. It makes the perfect sized 3-layer lasagna for this recipe and is the just right to make a meal that will not offer a lot of leftovers. When you are cooking for just 2 or 3 people, a 16 sized serving of lasagna just doesn’t work! I am also including a link to the Natural Heaven Veggie Noodles for your convenience!
