How to Make Slow Cooker Lentil Soup

Slow Cooker Lentil Soup

How to Store and Serve Slow Cooker Lentil Soup

This lentil soup meal prep recipe is a perfect one-portion meal. Just divide this meal prep recipe evenly in four single-compartment containers, fill your fridge or freezer, and forget about it!

This lentil soup meal prep will last for about 5 days in the fridge, with one caveat. Lentils are best for your belly when they’re as fresh as possible. To reduce the chances of belly-bloating, eat this meal prep recipe as soon after cooking and add the spice hing to support digestion if you are sensitive to legumes.

If you're freezing this soup, it will keep in the freezer for up to 6 months. Defrost overnight in the fridge, right on the stovetop, or in the microwave, depending on your preference and how much time you have available.

We love to eat this soup as is, because it's a pretty complete meal, but do serve with a side salad if you want and, if you're not gluten-free, a hunk of crusty bread or a handful of crackers.

Substitutions and Variations

We have specified standard green lentils here, but you may notice there are a few different kinds. If you use red lentils, this soup will cook in much less time and the lentils will pop open and get starchy. That's because red lentils are different from green ones in that regard! You want to steer clear of the French puy lentils, which are best for salads and other cooked dishes.

You can vary the amounts of the ingredients if desired (just don't change the liquid amount). Add sweet potatoes or Yukon gold potatoes, cut into ½-inch cubes, if you want something even heartier and love potatoes with lentils like we do. Lentil soup is a bit of a blank slate.

Tips for Making Slow Cooker Lentil Soup:

  1. Don’t worry about soaking your lentils because the slow cooker will take care of the tenderness.
  2. Do rinse and sift your lentils before cooking because sometimes there are rocks. Remove debris now and you’ll thank yourself later.
  3. Asafoetida (also known as hing) is an additional spice/powder known for reducing the gas-forming qualities of legumes, including lentils. If you are sensitive to beans, try it!

    1. Sure. We haven't tested with Kale, but it should be a good swap. May need to cook a little longer to break down the kale a bit more?

    1. Hi Amanda, We don't calculate the exact serving size. The recipe makes 4 meals, so should be evenly divided into 4 portions.
