How to Make Crockpot Lentil Soup

Step 1: Sauté the Aromatics

Start by getting a skillet warm. Use about one tablespoon of olive oil. Add your chopped yellow onion. Put in the diced carrots too. Add the celery that you diced. Cook these for about 5 to 7 minutes. Stir them often. You want them to start getting soft. This step is not mandatory. However, it does create a deeper flavor. It makes your slow cooker lentil soup much richer. Now, add the minced garlic. Cook it for just one more minute. Let it become fragrant. Be very careful not to burn the garlic. If you are rushed for time, you can skip this. Just add the raw vegetables straight into the slow cooker.

Step 2: Combine Ingredients in the Slow Cooker

Move the sautéed veggies. Put them into your slow cooker crock. If you skipped seasoning the vegetables, add your raw chopped ones now. Add the 28-ounce can of crushed tomatoes. Pour in the six cups of vegetable broth. Next, add the 1.5 cups of rinsed lentils. Make sure they are brown or green types. Do not forget the teaspoon of dried thyme. Add the bay leaf. Stir everything well. This ensures all ingredients mix together nicely inside the slow cooker.

Step 3: Cook the Soup

Put the lid securely on the slow cooker. Set it to the LOW setting. Let the soup cook for 6 to 8 hours. Alternatively, use the HIGH setting. Cook for 3 to 4 hours then. Your cooker model might affect time. Cook it until the lentils are tender. This slow cooker lentil soup needs minimal fuss. The goal is tender lentils. You want flavors to meld. It becomes a truly satisfying dish.

Step 4: Finish and Season

Cooking is done. The lentils are tender. Carefully remove the bay leaf. Throw it away. Stir in fresh spinach now. Do this if you are using it. The soup is hot. The heat will wilt the spinach. This only takes a few minutes. It adds color and nutrients. Now, taste your Crockpot Lentil Soup. Add salt and pepper as needed. Adjusting seasoning is very important. It brings out the best flavors.

Garnishes

To elevate your Crockpot Lentil Soup, a few simple garnishes make all the difference. A generous sprinkle of fresh parsley adds color. It offers a bright, herbaceous note. This cuts through the soup’s richness. For creaminess and tang, dollop plain Greek yogurt. A swirl of sour cream is also wonderful. A drizzle of good olive oil before serving enhances aroma. It adds pleasant richness. For a bit of crunch, try toasted croutons. Crispy fried onions are great too.

Make Ahead and Storage

Storing Leftovers

Leftover Crockpot Lentil Soup is a treasure for future meals! Once cooled, transfer the soup into airtight containers. I prefer glass containers. They do not retain odors. They are great for reheating. The soup stays fresh in the refrigerator. It is good for up to 4-5 days. If you added spinach, it might be softer. It will still be delicious. For best results when reheating, store any fresh garnishes. Keep parsley or yogurt separate.

Freezing

This Crockpot Lentil Soup recipe freezes beautifully. It is an excellent candidate for meal prepping! Let the soup cool completely. Portion it into freezer-safe containers. Use heavy-duty freezer bags too. For best texture, leave out spinach. Do not add garnishes before freezing. Properly stored, your lentil soup lasts. It can be kept frozen for up to 3 months. Thaw it overnight in the refrigerator. Gently reheat from frozen on the stovetop. Use low heat. Add a splash of broth if needed.

Reheating

Reheating this hearty soup is simple. The best method is on the stovetop. This maintains the texture. Transfer the soup to a saucepan. Heat it gently over medium-low heat. Stir it occasionally. Heat until it is warmed through. You can also reheat it in the microwave. Use 1-2 minute intervals. Stir between each step. Heat until hot. If you froze the soup, it might be thick. Add extra vegetable broth or water. Thin it to your liking. If you left out spinach, stir it in. Add this during the last few minutes of reheating.

Recipe Tips

• Preparation Tips: Rinse your lentils well. Use cold water. This removes dust. Chop vegetables evenly. This helps them cook uniformly.
• Cooking Techniques: For a thicker soup, mash lentils. Do this against the slow cooker side. Use a spoon. Do this near the end. Cooking time varies. Adjust it for your slow cooker.
• Substitutions: Add other root vegetables. Try parsnips or sweet potatoes. Use chicken broth for more flavor. This is fine if not vegetarian.
• Pro Tips: Sautéing vegetables adds flavor. Do this before the slow cooker. It enhances your Crockpot Lentil Soup Recipe.
