- 1 onion, finely diced
- 3 garlic cloves, minced
- 2 carrots, chopped
- 2 celery stalks, diced
- 1 tsp cumin (adds a warm, earthy flavor)
- 1 tsp smoked paprika (for a subtle smoky depth)
- 4 cups vegetable broth (or chicken broth for non-vegans)
- 2 cups fresh spinach, roughly chopped
- Salt and pepper to taste

Optional Add-Ins:
- 1 can diced tomatoes for extra acidity

Timing
This Lentil Soup with Spinach takes just 45 minutes from start to finish—10 minutes of prep and 35 minutes of cooking. Compared to traditional stews that simmer for hours, this recipe is 60% faster without sacrificing depth of flavor.
Step-by-Step Instructions
Step 1: Sauté the Aromatics
Heat olive oil in a large pot over medium heat. Add the onion, garlic, carrots, and celery, sautéing for 5 minutes until softened. This builds the flavor foundation for your Lentil Soup with Spinach.
Step 2: Toast the Spices
Stir in the cumin and smoked paprika, letting them toast for 30 seconds until fragrant. This unlocks their essential oils, intensifying the soup’s aroma.
Step 3: Simmer the Lentils
Add the lentils and broth, bringing the mixture to a boil. Reduce heat to low, cover, and simmer for 25 minutes until lentils are tender. Pro tip: Stir occasionally to prevent sticking.
Step 4: Add the Spinach
Fold in the fresh spinach and lemon juice, cooking just until the spinach wilts (about 2 minutes). Season with salt and pepper to taste.
