How to Make Caramelized Onion Red Lentil Soup
Step 1: Heat the Olive Oil
Start by heating the olive oil in a large pot or Dutch oven over medium heat. The oil should shimmer just slightly.
Step 2: Sauté the Onions
Add the sliced onions along with a generous pinch of salt. Cook, stirring occasionally, for about 15-20 minutes. During this time, watch as the onions gradually deepen in color and develop a sweet aroma. The sugar in the onions caramelizes beautifully, bringing out their natural sweetness.
Step 3: Add Garlic and Spices
Once the onions turn to a golden-brown hue, stir in the minced garlic, cumin, and smoked paprika. Sauté for another 1-2 minutes until the spices become fragrant, filling your kitchen with their warm and tantalizing perfume.
Step 4: Introduce the Carrots
Toss in the diced carrots and cook for an additional 5 minutes. The carrots will soften, further sweetening the mixture and adding vibrant color to your soup.
Step 5: Combine Lentils and Liquids
Now, it’s time for the stars of your soup! Add the rinsed red lentils, vegetable broth, and diced tomatoes. Stir everything together, ensuring that the ingredients mingle beautifully.
Step 6: Bring to a Boil
Bring the pot to a gentle boil. Once it’s bubbling, reduce the heat to low. Cover the pot, letting it simmer for about 20 minutes, or until the lentils become tender and melt into the soup.
Step 7: Blend if Desired
If you enjoy a smoother texture, carefully use your immersion blender to puree the soup until it reaches your desired consistency. For those who prefer a chunkier texture, skip this step and leave it as is.
Step 8: Final Seasoning
Stir in the salt, black pepper, and lemon juice. Taste and adjust seasonings as needed, allowing the bright acidity of lemon to enhance the overall flavors.
Step 9: Serve and Garnish
Pour the soup into bowls, garnishing each serving with a sprinkle of fresh parsley or cilantro for an extra burst of flavor. Serve hot and smile as everyone digs in.
