Recipe Tips and Tricks

Sauté First for Extra Flavor: While not necessary, sautéing the onions, garlic, and carrots before adding them to the slow cooker deepens the soup’s flavor.
Use the Right Lentils: Green or brown lentils hold their shape best in a slow cooker, while red lentils break down into a creamier texture.
Layer Your Ingredients: Place heartier vegetables like carrots and celery at the bottom, then add lentils, seasonings, and broth for even cooking.

Don’t Overdo the Salt Early On: Lentils absorb flavors as they cook, so adjust the seasoning towards the end for the best taste.
Add Greens at the End: If you’re using spinach or kale, stir them in during the last 10 minutes to retain their vibrant color and nutrients.

Ingredients

1 ½ cups brown or green lentils, rinsed
1 medium onion, diced
2 carrots, peeled and chopped

2 celery stalks, chopped
3 garlic cloves, minced
1 can (14.5 oz) diced tomatoes

6 cups vegetable broth
1 teaspoon ground cumin
1 teaspoon smoked paprika

½ teaspoon dried oregano
½ teaspoon ground cinnamon (optional)
½ teaspoon salt (adjust to taste)

¼ teaspoon black pepper
2 cups chopped spinach or kale
2 tablespoons olive oil

1 tablespoon fresh lemon juice

Instructions

Prepare the Ingredients: Rinse the lentils under cold water and drain. Dice the onion, carrots, and celery. Mince the garlic for extra aromatic flavor.
Layer the Ingredients in the Slow Cooker: Add the chopped onions, carrots, and celery to the bottom of the slow cooker. Then, add the rinsed lentils, minced garlic, diced tomatoes, and all the spices—cumin, smoked paprika, oregano, cinnamon (if using), salt, and pepper.

Pour in the Broth: Slowly pour in the vegetable broth, ensuring everything is well submerged. Give the mixture a gentle stir to distribute the spices evenly.
Set and Forget: Cover and cook on low for 6-8 hours or high for 3-4 hours until the lentils are tender and the flavors have melded beautifully.
Add the Greens: In the last 10 minutes of cooking, stir in the chopped spinach or kale. This ensures they retain their color and nutrients.

Finish with Olive Oil and Lemon: Just before serving, drizzle in the olive oil and stir in the fresh lemon juice. These final touches brighten the soup and enhance its Mediterranean flavors.
Serve and Enjoy: Ladle the soup into bowls, garnish with fresh parsley if desired, and enjoy with warm crusty bread or pita.

Notes

This soup thickens as it sits. Add a little water or broth when reheating if you prefer a thinner consistency.

It’s even better the next day, as the flavors continue to develop overnight!

Ingredients Notes

Lentils: Brown or green lentils are ideal for this soup as they hold their shape and provide a slightly chewy texture. If you prefer a softer, creamier consistency, red lentils are a great option.
Vegetables: Carrots, celery, and onions form the aromatic base, while diced tomatoes add a touch of acidity and depth. Feel free to add zucchini, bell peppers, or even potatoes for variation.
Broth: Vegetable broth keeps this soup plant-based, but you can use chicken broth for extra richness if preferred.

Olive Oil: A generous drizzle of extra virgin olive oil at the end enhances the Mediterranean flavors and adds a smooth finish.
Spices & Herbs: Cumin, smoked paprika, and oregano bring warmth and depth. A hint of cinnamon or coriander can add another layer of flavor.
Lemon Juice: A squeeze of fresh lemon at the end brightens the flavors and balances the dish.

Variations and Substitutions

Make It Creamy: Blend a portion of the soup for a thicker, creamier consistency.
Protein Boost: Add cooked shredded chicken, turkey, or chickpeas for an extra protein punch.
Spicy Kick: Stir in a pinch of red pepper flakes or harissa for added heat.

Different Greens: Instead of spinach, try kale, Swiss chard, or collard greens.
Grain Additions: Stir in cooked quinoa, barley, or rice for a heartier meal.
Tomato-Free Option: If you’re avoiding tomatoes, replace them with extra broth and a splash of balsamic vinegar for depth.

Storage Options

Refrigeration: Store in an airtight container for up to 5 days. The flavors will deepen over time, making it even tastier the next day!
Freezing: This soup freezes beautifully! Portion into freezer-safe containers and store for up to 3 months. Thaw overnight in the fridge and reheat on the stovetop.
Reheating: Warm gently over low heat, adding a splash of broth if needed to loosen the consistency.
