FAQs

Can I use red or brown lentils instead of green?

Yes, but red lentils cook faster and break down more, resulting in a creamier soup. Brown lentils work similarly to green.

Do I need to soak the lentils first?

No soaking is necessary for green lentils, but rinsing them before use is recommended.

Can I use frozen butternut squash?

Yes, frozen squash works well. Add it directly to the pot; no need to thaw.

What kind of stock is best?

Vegetable stock keeps the soup vegan, but chicken stock adds a deeper savory flavor if you're not plant-based.

How do I thicken the soup more?

Simmer uncovered for a few extra minutes or mash some of the lentils with a spoon.

Can I make this soup in a slow cooker?

Yes. Sauté the onions, garlic, and squash first, then transfer everything to a slow cooker. Cook on low for 6–8 hours.

Can I use pre-cooked lentils?

Yes, reduce the simmering time and add pre-cooked lentils halfway through to avoid overcooking.

What type of yogurt is best for topping?

Plain Greek yogurt adds creaminess and tang, while coconut yogurt keeps it dairy-free and vegan.

How can I make this soup smoother?

Blend partially or fully with an immersion blender for a smoother consistency.

Is this soup freezer-friendly?

Yes, it freezes well. Just cool completely and store in freezer-safe containers.
