Notes
Storage:Â Store leftover soup in an airtight container in the fridge for up to 3 days. It freezes well for up to 3 months in an airtight container or freeze-safe bags and can be reheated in the microwave.This crockpot lasagna soup recipe will thicken even more to the point of being stewy when it sits in the fridge, as the noodles absorb the liquid. You can simply add a little more beef stock if you like it thinner.Top tipsI also love to use a meal mug (affiliate link) to take this soup to work. I freeze it in the same mug, then pop it in the microwave and have it for lunch!You will have leftover dry cottage cheese, but it does freeze well for up to 3 months, if you place the container in a large ziplock freezer bag.You can also use up leftover dry cottage cheese (aka farmer's cheese) in one of these 15 recipes with Farmers Cheese !Variations & Substitutions
Spinach - you can use fresh spinach instead of frozen
Cottage cheese- you can use regular cottage cheese instead of dry cottage cheese but it's important you drain it and cook the soup on the LOW setting (see ingredient notes above).
Vegetarian - the beef hamburger can be replaced with a plant-based burger to make this vegetarian lasagna soup or skip the meat altogether
Lasagna Noodles- you can use a fresh noodle that's easier to cut OR a different kind of pasta (such as bowtie). Or you can use whole wheat regular lasagna noodles (you'll need to add them earlier)
Meat - you can make this lasagna soup with ground turkey or ground chicken instead of ground beef
Tomato sauce - you can substitute marinara sauce
Canned Diced Tomatoes - you can use crushed tomatoes instead
