Ingredients for Lentil Kale Soup

For this recipe you'll simmer in a large pot on the stove:

Yellow onion: Or you can use white onion or sweet onion if desired.
Carrot
Fresh garlic cloves: I like the taste of fresh, but you can substitute 1-2 teaspoons dried garlic powder instead.
Gold potato: I like Yukon gold potatoes with this recipe because they're flavorful and buttery, but white potato, red potato, or russet potato work great too.
Green lentils or brown lentils: These are a great source of plant-based protein and fiber. I like the earthy taste and texture of green or brown lentils with this recipe. I haven't tested it with red lentils or black lentils, but they could probably work too. (Red lentils are slightly sweeter, and will create more of a stew-like consistency after they boil.)
Diced tomatoes: Either use regular or fire-roasted canned tomatoes.
Vegetable broth: Be sure to use low sodium if desired.
Fresh kale: Any type of kale will work such as curly or lacinato kale. Stir in as much or as little as you would like. You could also substitute with swiss chard or fresh baby spinach.
Ground cumin
Smoked paprika: You can also add salt and black pepper to taste.

Customizing

Herbs & seasonings: I like the warm taste of cumin and smoked paprika, but this would be great with many other flavors too. Switch it up with dried basil, dried oregano, Italian seasonings, bay leaves (remove before serving), rosemary, or curry powder. Or garnish your bowl with fresh parsley or a squeeze of lemon juice before serving.

Make it spicy: Add fire-roasted tomatoes with medium diced chiles, cayenne pepper, or simply top with your favorite hot sauce before enjoying.

Vegetables: Add other veggies as desired. Zucchini, celery, yellow summer squash, bell pepper, spinach, green beans, peas, mushrooms, sweet potatoes, swiss chard, etc.

Thickness: This soup is beautifully dense! If you prefer yours with more broth, then reduce lentils (to about 2/3 cup to 3/4 cup instead of 1 cup). Or simply add more broth or water during cooking.

Storing

After it cools, store leftovers in an airtight container in the refrigerator. I find it keeps well for about 4-5 days. It's a great leftover meal! The flavors only enhance and get better as it sits. Simply reheat in the microwave when ready to enjoy.

Freezing: I haven't personally tried this soup as a freezer meal, but readers have reported success with freezing it for later!
