Common Questions

Can I use red lentils instead of green or brown lentils?

Red lentils cook much faster and break down more easily, creating a creamier texture. If using red lentils, reduce the simmering time to about 15 minutes and expect a thicker, less chunky consistency.

How do I store leftover soup?

Store in an airtight container in the refrigerator for up to 5 days. The soup may thicken as it sits, so add a splash of broth or water when reheating. It also freezes well for up to 3 months.

Can I skip roasting the vegetables?

Yes, you can add the raw diced vegetables directly to the pot after sautéing the onion. However, roasting adds depth of flavor and caramelization that enhances the overall taste of the soup.

What other vegetables work well in this soup?

Sweet potatoes, butternut squash, kale, spinach, green beans, or parsnips are excellent additions. Add heartier vegetables like squash with the lentils, and stir in leafy greens during the last 5 minutes of cooking.

How can I make this soup more filling?

Serve with crusty bread, add cooked quinoa or farro, increase the lentil quantity to 1.5 cups, or stir in chopped potatoes. You can also top with a dollop of Greek yogurt or sour cream if not maintaining a vegan diet.

Why are my lentils still hard after cooking?

Old lentils take longer to soften. Adding acidic ingredients like tomatoes or lemon juice too early can also slow cooking. Ensure lentils are fully submerged in liquid and simmer gently until tender, adding more time if needed.
