Ingredients Needed

Before you start cooking, make sure you have everything on hand. Here’s what you’ll need:

Main Ingredients

1 ½ cups dried green or brown lentils – These are the star of the soup, providing a hearty, earthy base.
1 medium onion, chopped – Adds a savory depth of flavor to the soup.
2 carrots, peeled and diced – A touch of sweetness and color.
2 celery stalks, diced – Adds crunch and freshness.
3 garlic cloves, minced – For that aromatic kick.
1 (14.5 oz) can diced tomatoes – For acidity and a bit of sweetness.
4 cups vegetable broth – This serves as the base liquid and enhances the overall flavor.
1 teaspoon ground cumin – A warm, earthy spice that gives the soup a bit of complexity.
1 teaspoon turmeric – Adds an extra layer of flavor and vibrant color.
1 teaspoon dried thyme – Brings out a herby, woody flavor.
1 bay leaf – For subtle depth in flavor.
Salt and pepper, to taste – Enhances all the flavors and balances the soup.

Optional Ingredients

1 tablespoon lemon juice – For a bright, zesty finish.
A handful of spinach or kale – If you want to add some greens to your soup.
Olive oil – To sauté the vegetables if you prefer a richer flavor.
Red pepper flakes – For a bit of heat.

Cooking Instructions

Here’s how you can make your Crockpot Lentil Soup:

Prepare the Veggies: Start by chopping the onion, carrots, celery, and garlic. This will ensure that everything cooks evenly in the crockpot.
Layer the Ingredients in the Crockpot: Add the lentils, chopped vegetables, garlic, diced tomatoes (with juices), vegetable broth, spices, and bay leaf to the crockpot. Give it all a quick stir to distribute the ingredients evenly.
Cook Low and Slow: Cover the crockpot and set it to low for 6-8 hours. If you’re in a rush, you can set it to high for 3-4 hours, but slow cooking is best for developing deeper flavors.
Check for Doneness: About 30 minutes before serving, taste and adjust the seasonings with more salt, pepper, or spices if needed. If you want to add spinach or kale, stir it in at this point.
Serve & Garnish: Once the lentils are tender and the broth has thickened to your liking, turn off the heat. Optionally, squeeze a bit of lemon juice over the soup to brighten it up and serve with some crusty bread or crackers.

Ingredient Insights

Lentils: Lentils are not only high in protein but also loaded with fiber, making them great for digestion and heart health. They’re also a fantastic source of iron, which is especially beneficial if you’re vegetarian or vegan.
Vegetable Broth: A good-quality vegetable broth will enhance the soup’s flavor and make it rich. If you prefer, you can use chicken broth for a heartier taste, but vegetable broth keeps it lighter.
Tomatoes: Tomatoes add a touch of sweetness and acidity, balancing the earthiness of the lentils. They also provide a natural source of vitamin C.
Garlic & Spices: Garlic adds a wonderful aromatic depth to the soup, while cumin and turmeric offer a unique flavor profile. Together, these spices create a warming, satisfying experience.

Expert Tips

Soak the Lentils: While it’s not strictly necessary, soaking lentils overnight can help them cook more evenly and reduce the cook time slightly. Just make sure to drain and rinse them well before adding to the crockpot.
Use a Fat Separator: If you’re using a store-bought broth, consider using a fat separator to remove excess fat from the broth before adding it to the soup. This will result in a cleaner, lighter taste.
Stir Occasionally: If you’re home during the cooking process, it’s a good idea to give the soup a quick stir once or twice to make sure the ingredients are well combined.
Make it Creamy: If you prefer a creamier texture, blend a portion of the soup using an immersion blender or a regular blender. This will give the soup a velvety finish while still maintaining some of the lentil texture.

Recipe Variations

Add Protein: If you’re looking for a meatier soup, you can add shredded chicken, turkey, or even sausage. Just make sure to adjust the cooking time depending on the protein you add.
Spicy Version: If you like some heat, toss in some red pepper flakes, or use a spicy chili powder blend. You can also add a diced jalapeño or two for extra kick.
Herby Twist: For a more herbaceous flavor, add fresh herbs like rosemary, parsley, or cilantro in place of dried thyme. Fresh herbs will give a lively, fresh quality to the soup.
Add Potatoes: If you’re craving a more filling soup, adding diced potatoes is a great way to bulk it up. Potatoes will cook down into the broth and make the soup even more hearty.

Final Words

Crockpot Lentil Soup is one of those dishes that’s as versatile as it is comforting. It can be modified to suit any taste and is a perfect option for meal prep or a quick weeknight dinner. The beauty of this recipe lies in how you can easily adapt it based on what you have on hand or your personal preferences.
