Spray a large nonstick saucepan with nonstick spray and set over medium-high heat. Add the bacon and cook until browned, 2 ? 3 minutes. Transfer the bacon to paper towels to drain.

Add the onion and jalapeno to the saucepan. Cook, over medium-high heat, stirring occasionally, until the onion is tender, about 5 minutes. Stir in the flour; cook 1 minute. Add the broth, potatoes, and salt; bring to a boil. Reduce the heat and simmer, covered, until the potatoes are tender, about 12 minutes. Add the corn, milk, half-and half. Cook 1 minute. Remove from the heat. Stir in the cheese and cilantro; sprinkle with the bacon.
