Tex-Mex Green Bean Casserole

Total Time:
1 hr 10 min
30 min
40 min

6 to 8 servings

  • Kosher salt
  • 2 pounds green beans, trimmed and halved
  • 3 tablespoons unsalted butter
  • 3 poblano chile peppers, seeded and cut into short strips
  • 1 large onion, chopped
  • 2 cloves garlic, minced
  • 2 tablespoons all-purpose flour
  • 1 1/2 cups half-and-half
  • 1 1/2 cups low-sodium chicken broth
  • Pinch of cayenne pepper
  • 2 cups shredded pepper jack cheese (about 8 ounces)
  • 4 cups tortilla chips
  • 1 teaspoon ancho chile powder
  • 1/2 cup crumbled Cotija cheese (about 2 ounces)
  • Preheat the oven to 375 degrees F. Bring a large pot of salted water to a boil. Add the green beans and cook until crisp-tender, about 6 minutes. Drain, rinse under cold water and blot dry with paper towels.

  • Melt the butter in a large pot or Dutch oven over medium heat. Add the poblanos and onion, season with salt and cook, stirring occasionally, until tender, about 7 minutes. Add the garlic and cook 1 minute. Add the flour and cook, stirring, until the vegetables are coated, about 1 minute.

  • Whisk in the half-and-half, chicken broth, cayenne and 1/2 teaspoon salt. Increase the heat to medium high and bring to a boil, then reduce the heat to medium low and simmer, whisking occasionally, until thickened, about 5 minutes. Add the pepper jack and stir until melted, then add the green beans and stir to coat. Transfer to a 3-quart baking dish. (You can refrigerate the casserole, covered, for up to 4 hours.)

  • Bake the casserole until bubbling, about 20 minutes. Meanwhile, pulse the tortilla chips with the chile powder in a food processor until coarsely ground. Sprinkle the Cotija cheese and ground tortilla chips over the casserole; bake until golden, about 5 more minutes.
