How to Make Best Lentil Soup Recipe

Step 1: Sauté the Aromatics

Begin by heating the extra-virgin olive oil in a large pot over medium heat. Toss in the chopped onion, carrots, celery, and diced kale stems along with ground cumin, sea salt, and fresh black pepper. Stir this fragrant mix occasionally for about 8 minutes until the vegetables start to soften and their natural sweetness blossoms.

Step 2: Build the Soup Base

Next, add the grated garlic to the pot, letting it warm through for a minute until aromatic. Pour in the fire-roasted diced tomatoes, drained and with all their smoky goodness, then stir in the rinsed green lentils. Add the white wine vinegar, fresh thyme sprigs bundled together for easy removal later, and pour in the vegetable broth to cover everything. This combination creates the hearty base of the soup.

Step 3: Simmer and Tenderize

Bring the soup to a gentle simmer, cover the pot, and let it cook for 25 to 30 minutes. This allows the lentils to soften thoroughly while the flavors marry beautifully. You’ll smell the wonderful blend of herbs and spices as the soup thickens nicely.

Step 4: Add Kale Leaves and Final Seasoning

In the last 5 minutes of cooking, stir in the chopped kale leaves. They will wilt down and add a lovely texture and vibrant green color. Once done, remove the thyme bundle and adjust seasoning if needed. Your Best Lentil Soup Recipe is now ready to be ladled into bowls.

Garnishes

To elevate your bowl, sprinkle chopped fresh parsley on top for a burst of color and fresh flavor. If you enjoy a bit of spice, red pepper flakes add a nice kick.

Side Dishes

This soup shines brightest when paired with warm, crusty bread that’s perfect for dipping. A simple side salad or roasted vegetables also work well to round out the meal without overpowering the soup’s lovely flavors.

Creative Ways to Present

If you want to impress guests, serve the soup in rustic bowls and top it with a drizzle of good olive oil or a dollop of yogurt for extra creaminess. Adding a few toasted seeds or nuts on top provides delightful crunch that contrasts beautifully with the tender lentils.

FAQs

Can I use brown or red lentils instead of green lentils?

Yes, you can substitute brown or red lentils, but keep in mind they have different cooking times and textures. Red lentils will cook faster and become soft, while brown lentils hold their shape a bit more like green lentils.

Is this recipe suitable for vegans?

Absolutely! Simply omit the Parmesan cheese garnish to keep it vegan-friendly without sacrificing any flavor or heartiness.

Can I make this lentil soup in a slow cooker?

Definitely. Use the same ingredients, cook the aromatics on the stovetop first, then transfer to a slow cooker and cook on low for 6 to 8 hours or on high for about 3 to 4 hours.

What can I do if the soup is too thick?

If your soup thickens too much, just stir in extra vegetable broth or water until it reaches your desired consistency.

How long does the soup keep in the freezer?

For best quality, freeze your lentil soup for up to 3 months. Beyond that, it’s still safe but might lose some fresh flavor and texture.
