What type of lentils should I use in this soup?

We'd recommend brown or green lentils. Red lentils are split which means they'll soften a lot faster.

Can you make this soup in the Instant Pot?

Yes! Place the first group of ingredients below in the Instant Pot and cook on the soup setting for 30 minutes with a quick release at the end. Follow the same blending instructions and then add kale and parsley.

My lentils are still hard! How do I fix this?

Let the soup cook a little longer on the high setting to soften them up! If using the Instant Pot, you could re-pressurize to cook for another 5 minutes, or turn on the sauté mode until they soften.

How big of a crockpot or Instant Pot do I need to use?

This makes a lot of soup! We'd recommend at least a 6-qt. for both.

Can you freeze this lentil soup?

Yes! You could freeze leftovers to keep in the freezer for three months, or make it a freezer meal by following the instructions in the recipe card notes or by checking out this post.

3/4 cup yellow split peas (or just use more lentils)

Instructions

Place all ingredients in the crockpot. Cover and cook on high for 5-6 hours or low for 7-8 hours.
Place about 4 cups of soup in a blender with the olive oil. Pulse gently until semi-smooth and creamy-looking (the oil will form a creamy emulsion with the soup). Add back to the pot and stir to combine. Stir in the kale and parsley. Turn the heat off and just let everything chill out for a bit before serving. The taste gets better with time and so does the texture, IMO!
Season to taste (add the sherry, vinegar, and/or lemon juice at this point) and to really go next level, serve with crusty wheat bread and a little Parmesan cheese. It’s called Detox Balance. 😉
