First Step: Prep IngredientsStart by slicing the 400 g chicken breast into 1 cm thick steaks. Season lightly with 1/4 teaspoon salt and black pepper. Dice one onion, crush two garlic cloves, and drain and rinse 600 g canned white beans. Prepare 2 to 4 tablespoons of finely chopped canned jalapeños or green chilies.

Second Step: Cook the ChickenHeat 1 tablespoon of olive oil in a large pot over medium-high heat. Cook the chicken steaks in batches for about 2 minutes per side until golden and just cooked through. Remove from the pot and allow to cool before shredding into bite-sized pieces.

Third Step: Sauté Aromatics and Create RouxReduce heat to medium, add 2 tablespoons of butter to the pot and melt. Sauté diced onions and crushed garlic for about 3 minutes until softened and translucent. Stir in 3 tablespoons of plain flour and cook for 2 minutes to get rid of the raw flour taste, continuously stirring to form a roux.

Fourth Step: Add Broth and MilkGradually pour in 1 cup chicken broth while stirring continuously, scraping the bottom of the pot to lift browned bits. Follow by adding 4 cups of milk or substitute heavy cream for richer texture. Add 1 teaspoon each of cumin and coriander powders. Stir in the jalapeños or green chilies.

Fifth Step: Simmer and ThickenIncrease heat to medium-high and whisk occasionally until the soup thickens slightly, approximately 5 minutes. The creamy base should be smooth with subtle spicy undertones coming through.

Sixth Step: Finalize SoupWhisk in 1/4 cup sour cream for extra creaminess. Fold in shredded chicken, drained white beans, and 1 1/2 cups corn. Heat for about 1 minute until everything is warmed through without overcooking the components.

Final Step: Adjust Seasoning and ServeTaste and adjust salt and black pepper as needed. Serve your white enchilada soup hot with optional toppings such as crushed tortilla chips, cilantro, diced avocado, shredded cheese like Monterey Jack, or pico de gallo for texture and flavor contrasts. This soup pairs wonderfully with a light salad or crusty bread for a satisfying meal.
