How to Make Slow Cooker Lentil Soup

This recipe keeps things straightforward. Let your slow cooker work its magic, and you’ll be rewarded with a bowl of delicious, hearty goodness. Here’s everything you need to know to make it perfect.

What You’ll Need

Before we get started, here’s a quick look at the ingredients. They’re all pantry staples and fresh veggies that come together beautifully:

• 2 medium onions, diced
• 3 large celery stalks, diced
• 3 large carrots, diced
• 4 cups potatoes, diced
• 2 cups frozen corn
• 1 1/2 cups green or brown lentils, rinsed & drained
• 1 tablespoon garlic powder
• 2 teaspoons dried oregano
• 1 teaspoon dried thyme
• 3 tablespoons soy sauce (I recommend Bragg liquid aminos)
• 3 bay leaves
• 5 whole peppercorns
• 9 cups low-sodium vegetable broth
• Garnishes: Green onion, cilantro, parsley, Greek yogurt, shredded cheese, or tortilla chips

You’ll also need a slow cooker for this recipe. Any size above 6 quarts works great!

Step-by-Step Instructions

Cooking this easy lentil soup in the slow cooker is as simple as it gets. Follow these steps:

1. Add your ingredients. Combine all the vegetables, lentils, garlic powder, oregano, thyme, soy sauce, bay leaves, peppercorns, and broth in the slow cooker. No need to stir; the magic will happen while it cooks.
2. Cook low and slow. Cover and set your slow cooker to Low for 8–10 hours or High for 4–5 hours. Longer cooking times deepen the flavors, so go low and slow if you can.
3. Blend for creaminess. Once it’s done, discard the bay leaves and peppercorns. Use an immersion blender to pulse a few times for a creamy, chunky texture. (If you don’t have an immersion blender, transfer 1 cup of soup to a countertop blender, blend, and stir it back in.)
4. Serve and garnish. Ladle the soup into bowls and top with your favorite garnishes like fresh herbs, cheese, or a dollop of Greek yogurt. Don’t forget a few tortilla chips on the side for crunch!

Jake’s Tips for the Best Slow Cooker Lentil Soup

Here are a few of my best tricks to make this soup absolutely amazing:

• Use red lentils for extra creaminess. If you prefer a softer texture, swap green or brown lentils for red ones. Just keep in mind that they’ll break down more as they cook.
• Customize your veggies. Got leftover zucchini, spinach, or peppers? Toss them in! This recipe is super flexible, so use whatever you have on hand.
• Go for a smoky twist. Adding a teaspoon of smoked paprika or a splash of liquid smoke can give the soup a deeper, smoky flavor.
• Prep ahead for busy weeks. Freeze all the ingredients (except broth) in a large Ziploc bag. Thaw slightly and transfer to your slow cooker with the broth when you’re ready to cook. Easy peasy!
