Ingredients: Building the Foundation
Core Ingredients
- 1 cup dried green or brown lentils, rinsed and drained
- 2 tablespoons olive oil
- 1 medium onion, diced
- 2 medium carrots, peeled and diced
- 2 celery stalks, diced
- 3 garlic cloves, minced
- 1 can (14 oz) diced tomatoes (with juices)
- 6 cups vegetable broth (or water, if preferred)
Seasonings & Herbs
- 1 teaspoon ground cumin
- 1 teaspoon smoked paprika
- 1/2 teaspoon dried thyme
- 1 bay leaf
- Salt and freshly ground pepper to taste
Optional Additions
- 1/2 teaspoon red chili flakes (for heat)
- 1 cup chopped kale or spinach (for added greens)
- Juice of 1 lemon (for brightness)
Step-by-Step Cooking Instructions
1. Sauté the Aromatics
In a large pot, heat the olive oil over medium heat. Add the diced onion, celery, and carrots. Cook for 5–7 minutes, stirring occasionally, until vegetables are softened and slightly golden. Add the minced garlic and cook for an additional 1 minute, stirring constantly to prevent burning.
2. Add the Spices
Stir in cumin, smoked paprika, and dried thyme. Sauté for another minute, allowing the spices to release their aromas and coat the vegetables thoroughly.
3. Combine Lentils, Tomatoes, and Broth
Pour in the vegetable broth, scraping up any bits stuck to the bottom of the pot. Add the lentils, diced tomatoes, and bay leaf. Stir to combine.
4. Simmer to Perfection
Bring the mixture to a boil. Once boiling, reduce the heat to low and cover the pot. Simmer for 25–30 minutes or until the lentils are tender. Stir occasionally to ensure nothing sticks to the bottom.
5. Enhance the Flavor
Once the lentils are cooked, taste and season with salt and pepper. Add chili flakes if a little heat is desired.
6. Add Greens and Lemon (Optional)
If using kale or spinach, stir it in during the final 5 minutes of cooking. Remove the bay leaf and squeeze in the lemon juice just before serving.
