How to Make Slow Cooker Lentil and Vegetable Soup

Step 1: Prepare Your Ingredients

Wash and chop your vegetables into bite-sized pieces, rinse your lentils thoroughly, and gather your herbs and spices to ensure a smooth cooking process.

Step 2: Sauté Aromatics

In a skillet, heat olive oil and sauté onions, garlic, carrots, and celery until fragrant and slightly softened to enhance the soup’s depth of flavor before slow cooking.

Step 3: Combine in the Slow Cooker

Transfer the sautéed vegetables to the slow cooker, add lentils, tomatoes, vegetable broth, herbs, and spices. Stir everything together thoroughly.

Step 4: Cook on Low

Set your slow cooker to low and cook for 6 to 8 hours, allowing the lentils to soften and the flavors to meld perfectly.

Step 5: Add Greens and Final Seasoning

About 15 minutes before serving, stir in fresh spinach or kale, then taste and adjust seasoning with salt and pepper as needed.

Pro Tips for Making Slow Cooker Lentil and Vegetable Soup

• Rinse lentils well: This removes any dust or debris and prevents cloudiness in your soup.
• Sauté first: Cooking aromatics before slow cooking elevates the soup’s flavor profile dramatically.
• Don’t overfill: Leave space in your slow cooker to ensure even cooking and prevent spills.
• Season toward the end: Salt can toughen lentils if added too early, so season at the end for better texture.
• Use fresh herbs last: Add delicate herbs right before serving to keep their brightness and aroma intact.
