I love this butternut squash lentil soup because it’s warm, comforting, and perfect for chilly days. It’s one of those recipes that feels like a big, cozy hug in a bowl. I can’t wait for you to try it and see how simple ingredients come together to make something really special.
Some ingredients like butternut squash and red lentils might not be in your kitchen right now. Butternut squash is usually found in the produce section, and it’s a sweet, nutty vegetable that cooks down nicely in soups. Red lentils are different from the lentils you might have seen before—they cook faster and become soft, which helps make the soup creamy without needing cream. You can find them in the dried beans or international foods aisle at the supermarket.

Ingredients For Butternut Squash Lentil Soup Recipe
Butternut squash: A sweet and creamy vegetable that adds natural sweetness and thickness to the soup.
Red lentils: Small, quick-cooking lentils that help make the soup smooth and filling.
Onion: Adds a savory base flavor when sautéed.
Garlic: Gives a nice aromatic punch and depth to the soup.
Vegetable broth: The liquid that cooks everything together and adds extra flavor.
Cumin: A warm spice that adds earthiness and a little bit of smokiness.
Coriander: A spice with a citrusy, slightly sweet flavor that pairs well with cumin.
Salt: Enhances all the flavors in the soup.
Black pepper: Adds a mild heat and sharpness.
Olive oil: Used for sautéing the onion and garlic, adding richness and helping to bring out flavors.
Technique Tip for This Recipe
One of the most important steps in this Butternut Squash Lentil Soup Recipe is sautéing the onion and garlic until they’re translucent. This means cooking them just long enough so they become soft and a little see-through, but not browned. Here’s how you can do it:
- Heat the olive oil in your pot over medium heat. You want it warm but not smoking.
- Add the chopped onion and minced garlic to the pot.
- Stir them around every minute or so to keep them from sticking or burning.
- Watch closely—the onion will start to look clear and soft after about 5 to 7 minutes. That’s when you know they’re translucent.
Doing this step right makes a big difference because it brings out the natural sweetness in the onion and garlic, which adds a rich flavor to the whole soup. If you rush it or cook on too high heat, the garlic can burn and taste bitter, which nobody wants.
When I first tried this, I didn’t stir enough and ended up with some burnt bits at the bottom of the pot. It made the soup taste a little off. Now, I keep a close eye and stir often, and it always turns out great. Also, if you’re in a hurry, you can chop the onion and garlic smaller so they cook faster, but be careful not to let them brown too much.
Taking your time with this step really pays off because it builds the base flavor for the soup, making it cozy and delicious. Plus, the smell while sautéing is pretty amazing!
