Low Carb Lasagna Soup Recipe in the Instant Pot

warm bowl of keto lasagna soup with parlsey and topped with ricotta cheese

Lasagna is a popular comfort food dish. I have a delicious, easy keto lasagna recipe that you should check out. It is one of my most popular recipes. When the weather is cooler and winter sets in, I like to make soups in the Instant Pot. Keto soups are easy to make using a pressure cooker. You can sauté all your meat and vegetables in the pot and pressure cook the soup. The benefit is that dinner is ready quickly and you don’t have to babysit the stove. This low carb lasagna soup has all the flavors of traditional lasagna – tomatoes, vegetables, pasta, ground beef and cheese; however, it is served as a bowl of warm comforting soup. Top your lasagna keto soup with a dollop of ricotta cheese, a sprinkle of mozzarella cheese and some sprigs of fresh parsley.

Are Tomatoes Keto?

Tomatoes are okay to eat in moderation on the keto diet. One medium sized tomato has around 4 carbs in it. In this recipe, we use one can of diced tomatoes. This contributed to 12 net carbs for the entire lasagna soup. When you portion that out per serving, it is only 2 net carbs for one bowl of warm lasagna keto soup. If you wanted to cut down on carbs from the tomatoes, you could omit the tomato paste. It is there to enhance the tomato sauce flavor of the lasagna broth.

Is Worcestershire Sauce Keto?

Technically, Worcestershire sauce has sugar in it; however, the amount is so tiny that it’s not going to spike your blood sugar too much. Plus the amount used in most savory recipes is minuscule that it doesn’t add much to the carb count per serving. Given this argument, Worcestershire sauce is keto friendly.

Shirataki Noodles

Shirataki noodles are a gelatinous Japanese noodle made from the konjac yam. They are near zero carbs since this pasta is made up of water and glucomannan, a water soluble fiber. They are tasteless if eaten alone, but will take on the flavor of any dish you put them in. Shirataki noodles make a great alternative to traditional pasta in low carb recipes. Many people complain about the rubbery texture of most shirataki noodles on the market. My favorite brand of keto pasta is Zeroodle by Liviva. It combines oat fiber with the konjac noodle, so you don’t get that rubbery consistency and it is still very low carb with only 4 net carbs for the entire package of pasta! My favorite shape is the penne pasta; however, the rice or spaghetti shirataki noodles can work in this recipe too.

The best part…shirataki noodles can be cooked in an Instant Pot. They hold their form and don’t break down with the pressure. If you are still not a fan of konjac pasta or don’t have access to any, you can substitute with either cauliflower rice or cauliflower florets in your lasagna soup.

Instant Pot Pressure Cooker

Pressure cookers are a working parent’s dream come true. Especially with simple, multi-function pressure cookers out there, like the Instant Pot. You can safely have dinner on the table in less than 30 minutes with very little hassle, mess or dishes. Many meals can be cooked in just one pot – your pressure cooker! The pressure cooker that I use is by Instant Pot. It has multiple functions. It can sauté, slow cook, steam, pressure cooker and many more functions. They even have Instant Pots that can air fry! Using an Instant Pot will speed up your cooking time compared to if you were cooking the same meal on the stove top. It will cook between 2 to 6 times faster compared to cooking the same meal in a pot on a burner!

Stove Top Instructions

Don’t have an Instant Pot??? No problem, you can still make this comforting soup. The stove top method works just as well, it will just take longer but your lasagna soup will still be full of flavor. To cook your soup in the stove, add the olive oil, ground beef, onion, celery and garlic to a large stock pot. Sauté until ground beef has browned. Then add the remaining soup ingredients. Bring to a boil. Then reduce heat to low. Cover and let simmer on the stove for 30 minutes.

Keto Lasagna Soup Storage and Reheating Instructions

Store any leftovers in an air tight container in the refrigerator for up to 4 days. You could also place in a freezer safe Ziploc bag or container and freeze the soup for later use. Reheat the lasagna soup in the microwave or on the stove top until heat through.

Instant Pot Easy Keto Lasagna Soup: FAQS

What can I substitute for shirataki pasta?

How should I store leftovers?

Store any leftovers in an airtight container in the fridge for up to 3 days. You can also freeze the soup for up to a month!

Is this recipe suitable for meal prep?

Yes! This Keto Lasagna Soup is perfect for meal prep. Just make a batch ahead of time, portion it out, and reheat when you're ready to eat.

Definitely! You can omit the ground beef and use additional vegetables like mushrooms, bell peppers, or spinach, and replace the broth with vegetable broth.
