Most ingredients for this lentil vegetable soup are pantry staples, but you may need to pick up a few items if your kitchen is running low. Lentils are the star, lending protein and body to the soup. Warming spices like cumin and paprika give depth and aroma, while a can of diced tomatoes adds bright acidity to balance the broth. Olive oil, onion, garlic, carrots and celery form the classic flavor base that carries the dish.

Ingredients for Lentil Vegetable Soup
1 cup lentils — rinsed and drained. Lentils cook quickly and absorb flavors well.
1 medium onion — chopped, for a sweet-savory base.
2 cloves garlic — minced, to brighten and deepen flavor.
2 cups carrots — chopped, for natural sweetness and color.
2 cups celery — chopped, to add subtle earthiness and texture.
1 can diced tomatoes (about 14.5 oz) — adds tomato richness and acidity.
6 cups vegetable broth — the liquid base; use low-sodium if preferred.
1 tsp cumin — warm and earthy, it complements the lentils.
1 tsp paprika — for color and mild peppery sweetness.
1 tsp salt or to taste, and ½ tsp black pepper.
2 tbsp olive oil — for sautéing and added richness.
Technique Tip for Making This Soup
To build the best flavor, take time to properly sweat the aromatics. Sauté the onion and garlic in olive oil until soft and translucent — this releases their natural sugars and forms a deeper base. Add cumin and paprika to the hot oil and briefly toast them for 30–60 seconds before adding vegetables and liquids; this helps bloom the spices and intensify the final flavor. Simmer gently until the lentils are tender, and always taste and adjust salt and pepper at the end. A squeeze of lemon juice or a handful of chopped fresh herbs right before serving will brighten the soup.
