📝 About This Recipe

This soul-warming lentil soup is a staple in Mexican households, blending earthy legumes with the salty, smoky richness of crispy bacon. Infused with a traditional 'recaudo' of fire-roasted tomatoes and aromatics, this dish offers a perfect balance of protein-packed nutrition and deep, savory comfort. It is the ultimate 'comida casera' that tastes even better the next day as the flavors continue to meld and deepen.

🥗 Ingredients

The Base

  • 2 cups Dry Brown or Green Lentils (rinsed and picked over for stones)
  • 6 slices Thick-cut Bacon (chopped into 1/2-inch pieces)
  • 8 cups Chicken Broth or Water (low-sodium preferred)
  • 2 pieces Bay Leaves (dried)

The Recaudo (Tomato Base)

  • 3 large Roma Tomatoes (ripe, roughly chopped)
  • 1/2 medium White Onion (chopped)
  • 3 cloves Garlic (peeled)
  • 1/2 teaspoon Cumin Seeds (or ground cumin)

Vegetables and Seasoning

  • 2 medium Carrots (peeled and diced into small cubes)
  • 1 piece Celery Stalk (finely diced)
  • 1/2 cup Fresh Cilantro (finely chopped)
  • 1 teaspoon Kosher Salt (adjust to taste)
  • 1/2 teaspoon Black Pepper (freshly cracked)
  • 1 tablespoon Olive Oil (only if bacon is very lean)

For Garnish

  • 1-2 pieces Serrano Chile (thinly sliced for heat)
  • 1/4 cup Mexican Crema (for drizzling)
  • 1 piece Avocado (sliced or cubed)
  • 2 pieces Lime Wedges (for brightness)

👨‍🍳 Instructions

  1. 1

    Rinse the lentils thoroughly under cold running water and drain. Place them in a large heavy-bottomed pot or Dutch oven with 8 cups of broth/water and the bay leaves.

  2. 2

    Bring the pot to a boil, then reduce heat to low, cover, and simmer for about 20 minutes. The lentils should be halfway cooked (slightly tender but still firm).

  3. 3

    While the lentils simmer, place the chopped bacon in a large skillet over medium heat. Fry until the bacon is crispy and the fat has rendered out. Using a slotted spoon, remove the bacon and set aside on paper towels, leaving the fat in the pan.

  4. 4

    In the same skillet with the bacon fat, add the diced carrots and celery. Sauté for 5-6 minutes until the vegetables begin to soften and pick up the smoky flavor.

  5. 5

    Prepare the 'recaudo': In a blender, combine the chopped tomatoes, onion, garlic, and cumin. Blend until completely smooth. If the mixture is too thick, add a splash of water.

  6. 6

    Push the carrots and celery to the side of the skillet and pour in the blended tomato mixture. Cook over medium-high heat, stirring constantly, for 5-8 minutes. The sauce should darken in color and thicken—this 'frying' of the sauce is essential for authentic flavor.

  7. 7

    Carefully pour the sautéed vegetable and tomato mixture into the pot with the simmering lentils.

  8. 8

    Stir in half of the crispy bacon bits (reserve the rest for garnish to keep them crunchy).

  9. 9

    Season with salt and pepper. Remember that bacon and broth contain salt, so taste before adding the full amount.

  10. 10

    Cover and simmer the soup for another 15-20 minutes, or until the lentils are completely tender and the soup has thickened slightly.

  11. 11

    Stir in the fresh cilantro during the last 2 minutes of cooking to preserve its bright color and aroma.

  12. 12

    Remove the bay leaves. Taste one last time and adjust seasoning if necessary. If the soup is too thick, add a little more hot broth.

  13. 13

    Ladle the hot soup into bowls. Top with the reserved crispy bacon, avocado slices, a drizzle of crema, and a few slices of serrano chile if you like a kick.

💡 Chef's Tips

Don't salt the lentils at the very beginning; doing so can sometimes make the skins tough. Wait until they are partially cooked. For a deeper flavor, char the tomatoes, onion, and garlic on a griddle (comal) before blending them into the recaudo. If you prefer a creamier texture, take one cup of the finished soup, blend it until smooth, and stir it back into the pot. Store leftovers in the fridge for up to 4 days; the lentils will absorb liquid as they sit, so you may need to add a splash of water when reheating. If you want a vegetarian version, swap bacon for smoked paprika and use vegetable broth, though the bacon is traditional for this specific recipe.

🍽️ Serving Suggestions

Serve with warm corn tortillas or crusty 'bolillo' rolls for dipping. A side of Mexican red rice (Arroz Rojo) makes this a very filling and complete meal. Pair with a glass of cold 'Agua de Jamaica' (Hibiscus tea) to cut through the richness of the bacon. Top with a squeeze of fresh lime juice just before eating to brighten the earthy flavors of the lentils. Add a spoonful of salsa macha on top if you want an extra smoky, spicy finish.
