How to Make Lentil & Brown Rice Soup
Step 1: Prepare the vegetables
Dice the onion, carrots, and celery. Mince the garlic and set everything aside.
Step 2: Build the flavor base
Heat olive oil in a large soup pot over medium heat. Add the onion, carrots, and celery and cook until softened and fragrant. Stir in the garlic and cook briefly.

Add the lentils, tomatoes, bay leaves, salt, pepper, and water or broth. Bring to a gentle boil, then reduce the heat and simmer until the lentils are tender.

Frequently Asked Questions
Can I make lentil and brown rice soup ahead of time?
Yes. This soup is ideal for making ahead. The flavors deepen as it sits, making it even better the next day. Store it in an airtight container in the refrigerator for up to 5 days.
Does lentil and brown rice soup freeze well?
Absolutely. This soup freezes very well. Let it cool completely, then freeze in freezer-safe containers for up to 3 months. Thaw overnight in the refrigerator and reheat on the stove or in the microwave.
Should I cook the brown rice in the soup or separately?
For best texture, cook the brown rice separately and stir it into the soup before serving. Cooking rice directly in the soup can cause it to absorb too much liquid and become mushy, especially when reheating leftovers.
What type of lentils work best for this soup?
Brown or green lentils are best because they hold their shape while cooking. Red lentils cook much faster and will break down, creating a thicker, more stew-like texture.
Is this lentil and brown rice soup vegan?
Yes, as long as you use vegetable broth or water. The recipe is naturally vegetarian and easy to keep fully vegan without any substitutions.
Can I make this soup in a slow cooker?
Yes. Add all ingredients except the cooked rice to the slow cooker and cook on low for 6–7 hours or high for 3–4 hours, until lentils are tender. Stir in the cooked brown rice just before serving.
How can I add more flavor to lentil soup?
You can boost flavor by adding bay leaves, dried thyme, cumin, smoked paprika, or a splash of lemon juice or vinegar at the end. Using broth instead of water also adds depth.
Why did my soup get thick after storing?
Lentils and rice continue to absorb liquid as the soup sits. This is normal. Simply add a little water or broth when reheating to reach your desired consistency.
Can I add meat to this recipe?
Yes. Cooked shredded chicken, sausage, or ground turkey can be added if you prefer a non-vegetarian version. Add cooked meat toward the end so it doesn’t dry out.
Is lentil and brown rice soup healthy?
Yes. This soup is high in fiber, rich in plant-based protein, and made with whole-food ingredients. It’s filling, nourishing, and naturally low in fat, making it a great option for balanced meals.
Simple, nourishing, and endlessly comforting, this lentil and brown rice soup is the kind of recipe that earns a permanent spot in your rotation.
