Sprinkle both sides of the chicken breasts or thighs with a generous amount of salt and freshly ground black pepper. Ensure an even coating to enhance flavor. The seasoned chicken should have a fine layer of seasoning on each side, not just a few spots. This step is crucial as it will infuse the meat with taste before cooking.
Place a large pot on high heat and add the oil. Once hot, carefully place the chicken pieces in the pot. Cook each side for about 1 1/2 minutes until they turn light golden brown. Use tongs to flip the chicken; avoid overcrowding the pan to ensure even searing. Remove the chicken from the pot using a slotted spoon and set aside on a plate.
This step caramelizes the surface of the chicken, enhancing its flavor without fully cooking it.
Add the chopped onion and minced garlic to the pot used for making the broth. Cook over medium heat for 2 to 3 minutes, stirring occasionally, until the onions become translucent and fragrant. This step ensures that the soup has a rich flavor base. Watch out for burning; keep an eye on the heat level.
Once the aromatics are cooked, add the creamed corn, fresh corn kernels, chicken stock, milk, salt, and pepper to the pot. Stir well to combine all ingredients evenly. Place the pot over medium-low heat and bring the mixture to a gentle simmer. Simmer for about 10 minutes or until the flavors meld together and the soup thickens slightly.
Avoid bringing it to a rolling boil as this can cause the corn to break down too quickly, resulting in a less appealing texture.
Cut the chicken into 1cm (0.4 inch) cubes to ensure even cooking and a consistent texture in your soup. This step should be done simultaneously with preparing other ingredients, as indicated by 'Meanwhile.' The goal is to have uniform-sized pieces that will cook evenly throughout the dish.
Add the pasta to the soup, ensuring it's fully submerged. Stir gently to prevent sticking and distribute the pasta evenly throughout the broth. Cook for 3 minutes or until the pasta begins to soften, checking against the package instructions for the full cooking time. This step is crucial as undercooked pasta can be tough, while overcooked pasta may become mushy.
Gently stir in the cheese, ensuring it melts evenly into the soup. Once the cheese is fully incorporated, add the kale and stir continuously to prevent it from becoming tough or overcooked. Observe the soup as you stir; the kale should soften and turn bright green, indicating it has wilted properly.
Immediately before serving the Chicken and Sweet Corn Soup with Pasta, gently sprinkle a few slices of fresh green onions over each bowl. This adds a vibrant pop of color and a mild onion flavor that complements the soup's sweetness. Optionally, add a small amount of extra cheese for an extra layer of richness.
Serve the soup hot to ensure all ingredients are well combined and flavors are at their peak.
