4 slices bacon, cut into 1-inch pieces
1 medium onion, chopped
1/4 cup all-purpose flour
2 cans (14.5 ounces each) reduced-sodium chicken broth
1 large baking potato, peeled and diced
1 head broccoli (about 1 pound), cut into bite-size florets, stalks peeled and thinly sliced
1 package (10 ounces) frozen corn kernels
1/2 teaspoon dried thyme
1 cup whole milk
Coarse salt and ground pepper
In a large pot, cook bacon over medium-low, stirring occasionally, until crisp, 8 to 10 minutes. Using a slotted spoon, transfer to a paper-towel-lined plate. Increase heat to medium. Cook onion, stirring, until it begins to soften, 6 to 8 minutes.
Add flour; cook, stirring constantly, 30 seconds. Add broth and potato; bring to a boil. Reduce to a simmer; cook until potato is tender, about 10 minutes. Add broccoli, corn, thyme, and milk. Cook until broccoli is crisp-tender, 8 to 10 minutes. Season with salt and pepper.
Serve topped with bacon.
