Step-by-Step Instructions

Sautéing the Onions

Start with two large onions. Thinly slice them and heat 2 tablespoons of olive oil in a large pot over medium heat. Add the onions with a good sprinkle of salt. Cook the onions for about 20 to 25 minutes. Stir them often. This helps them caramelize evenly. You want them to turn a deep golden brown. Salt helps draw out moisture from the onions. This moisture is key for good caramelization.

Adding Aromatics

When your onions are caramelized, it's time to add flavor. Add 3 cloves of minced garlic, 1 teaspoon of ground cumin, and 1 teaspoon of smoked paprika. Stir well to combine. Cook this mixture for 2 to 3 minutes. You will know it's ready when the kitchen fills with a lovely aroma. This step adds a rich depth to the soup.

Cooking Lentils and Carrots

Now, add 1 cup of thoroughly rinsed red lentils and 2 diced carrots to the pot. Pour in 6 cups of vegetable broth and bring it to a rolling boil. Keep an eye on it to prevent boiling over. Once it boils, lower the heat to a gentle simmer. Leave the pot uncovered and let it cook for about 30 minutes. This allows the lentils and carrots to become tender and flavorful.

Blending the Soup

After cooking, take the pot off the heat. You can use an immersion blender to purée the soup. If you don’t have one, carefully use a standard blender. Blend in batches if needed, and remember to vent the lid to let steam escape. Blend until you reach your desired texture. You might want it smooth or a bit chunky, it's up to you.

Seasoning and Final Touches

Taste your soup now. Adjust the flavors with salt, pepper, and 1 tablespoon of fresh lemon juice. This adds a nice brightness. If the soup cools down, put it back on low heat to warm it through. Your delicious caramelized onion red lentil soup is now ready to serve!

Tips & Tricks

Perfecting Caramelization

To get the best caramelization, you need to pay attention to a few factors. First, choose the right onions. Yellow onions work best for this soup. They become sweet and rich when cooked. The heat level is also important. Use medium heat to avoid burning. Stir the onions often to help them cook evenly.

To save time, slice the onions ahead of time. You can even caramelize them the day before. Store them in the fridge and add them when you cook the soup. This way, you cut down on prep time.

Variations for Dietary Preferences

This soup is easy to adapt for different diets. It is already vegan since it uses vegetable broth. If you want to add protein, consider chickpeas or tofu. Both options blend well with the soup.

For gluten-free needs, check your vegetable broth. Some brands add gluten. Use a certified gluten-free broth to keep your soup safe.

Enhancing Flavor Profiles

You can play with flavors by adding more spices. Try curry powder or a pinch of cinnamon for warmth. If you like heat, add red pepper flakes or cayenne pepper. Both add a nice kick to the soup.

For garnishes, fresh herbs work wonders. Chopped parsley adds brightness. You can also use chives or cilantro. A drizzle of olive oil on top gives a rich finish. Enjoy your soup with a slice of crusty bread for a complete meal.

Variations

Spicy Red Lentil Soup

To turn up the heat, add chili or cayenne pepper. Start with a small amount. You can always add more if you want it spicier. For this version, add the spice right after the garlic. This step will allow the heat to blend into the soup. If you add more veggies, adjust the cooking time. You might need an extra five to ten minutes. Keep an eye on the lentils to ensure they soften well.

Creamy Version

If you like a rich texture, try adding coconut milk or cream. This will make the soup creamy and smooth. Add it in after blending the soup. Stir it well to combine. If you use cream, heat it gently. Avoid boiling it, as it can curdle. You might want to cut back on the broth a bit. This ensures the soup stays thick and luxurious.

Vegetable Additions

Adding veggies can boost flavor and nutrition. Consider spinach, kale, or bell peppers. Chop them into small pieces for even cooking. Add them with the lentils and broth. Check for tenderness after 30 minutes. If you add heartier vegetables like sweet potatoes, increase the cooking time by ten minutes. Adjust seasoning after adding new ingredients to keep the flavor balanced.
