Why You’ll Love This Lentil Soup

Grandma’s Lentil Soup is hearty, filling, and surprisingly easy to make. It’s packed with fiber-rich lentils and fresh vegetables that make every spoonful satisfying. It’s budget-friendly, vegan by default, and freezer-safe, so you can enjoy it on busy weeknights. The flavors are deeply savory with subtle layers from herbs and spices, and you can customize it with add-ins like spinach or a dash of lemon.

What Kind of Lentils Should I Use?

Brown or green lentils work best for Grandma’s Lentil Soup. They hold their shape beautifully after cooking, offering texture without turning mushy. Red lentils can be used if you prefer a creamier consistency, but they do break down more. If you’re aiming for a rustic, classic vibe, go with brown lentils. No need to soak them ahead of time—just give them a rinse and toss them in.
