Velvety Red Lentil Soup with Sizzling Aleppo Butter Step-by-step instructions

Before you start

Before you start, rinse the red lentils under cold water in a fine-mesh sieve until the water runs clear. Dice the onion, carrot, and potato into small, even pieces.

Mince the garlic. Measure out the broth, cumin, and salt. Cut the lemon into wedges and have the crusty bread ready. Set out your large pot, immersion blender, and small skillet.

Instructions

Sauté and Simmer

1. 1Sauté the vegetables
   Heat the olive oil in a large pot over medium heat. Add the onion, carrot, and potato. Cook, stirring occasionally, until the onion is translucent, about 5 minutes. Add the garlic and cook for 1 minute more.
   Look for The onion becomes soft and translucent, and the garlic is fragrant.
   Tip Dice the vegetables into small, even pieces so they cook evenly.
2. 2Add lentils and broth
   Stir in the rinsed red lentils, broth, cumin, and salt. Bring to a boil, then reduce the heat to low, cover, and simmer for 25 minutes, or until the lentils and vegetables are very tender.
   Look for The soup is bubbling gently and the lentils are plump and tender.
   Tip Rinse the lentils in a fine-mesh sieve before adding to remove any debris.

The onion, carrot, and potato should be softened and slightly golden. The lentils will have absorbed most of the liquid and become tender.

The soup will smell earthy and spiced. Before moving on, ensure the lentils are fully cooked—they should mash easily between your fingers.

Blend to Velvet

3. 3Blend until silky
   Using an immersion blender, puree the soup directly in the pot until completely smooth and velvety. If you don't have an immersion blender, carefully transfer the soup in batches to a countertop blender and blend until smooth.
   Look for The soup is completely smooth with no visible chunks.
   Tip Be careful when blending hot liquids; leave the lid slightly ajar to release steam.
4. 4Adjust consistency
   Return the soup to medium-low heat if needed. If the soup is too thick, add a little extra broth or water to reach your desired consistency. Taste and adjust salt if necessary.
   Look for The soup is thick enough to coat the back of a spoon but still pourable.
   Tip Keep the soup warm while you prepare the sizzling butter.

After blending, the soup should be completely smooth, with a velvety, creamy appearance. It should coat the back of a spoon. If any chunks remain, continue blending until perfectly smooth. The color should be a warm golden orange.

Sizzle and Serve

5. 5Make the sizzling butter
   In a small skillet, melt the butter over medium heat. Add the Aleppo pepper flakes and dried mint. Cook, swirling the pan, until the butter foams and becomes fragrant, about 1 to 2 minutes. Remove from the heat.
   Look for The butter is foamy and the spices are sizzling and aromatic.
   Tip Do not let the butter brown; it should just foam and become fragrant.
6. 6Ladle and garnish
   Ladle the hot soup into warm bowls. Drizzle each bowl with a spoonful of the sizzling Aleppo butter, making sure to include some of the pepper and mint. Serve with lemon wedges and crusty bread for dipping.
   Look for The butter sizzles as it hits the hot soup, releasing a spicy, minty aroma.
   Tip Squeeze fresh lemon juice over the soup just before eating for brightness.

The butter should be foamy and the Aleppo pepper and mint should be sizzling and fragrant. When poured over the soup, the butter should create a beautiful red swirl. The soup should be hot and steamy, ready for a squeeze of lemon and a chunk of crusty bread.

Common mistakes

Avoid overcrowding the pot when sautéing the vegetables; cook them in a single layer if possible. Don't skip rinsing the lentils, as this removes excess starch and prevents the soup from becoming gummy.

When blending, be careful with hot liquids—always vent the blender lid and start on low speed. Finally, don't let the butter brown; it should only foam and become fragrant, otherwise it will taste bitter.

How to tell it’s done

The soup is done when the lentils and vegetables are completely tender and the soup has thickened slightly. To check, take a spoonful and let it cool slightly; it should be smooth and creamy.

If you're using chicken broth, the soup is safe to eat as soon as it's simmered, but for the best flavor, let it simmer the full 25 minutes. The sizzling butter is ready when it is foamy and fragrant, but not browned.
