How to Make Southwestern Potato Gratin

  1. Preheat oven to 400°F (200°C).
  2. Char 4 poblano peppers over a gas flame or in a broiler until blackened on all sides. Place in a paper bag and let stand for 10 minutes.
  3. Peel, seed, and chop the charred poblanos.
  4. Butter a 13x9x2-inch glass baking dish.
  5. Sprinkle 2 cloves minced garlic over the bottom of the dish.
  6. Layer 1/4 of the sliced potatoes (about 2 cups) in the dish.
  7. Season with 1/2 teaspoon salt and 1/4 teaspoon black pepper. Top with 1/3 of the chopped poblanos (about 1 cup) and 1/3 cup chopped cilantro.
  8. Repeat layers twice more: potatoes, salt & pepper, poblanos, cilantro.
  9. Top with remaining potatoes (about 2 cups).
  10. Pour 1 1/2 cups chicken broth over the potatoes, followed by 1 cup heavy cream.
  11. Season with 1/2 teaspoon salt and 1/4 teaspoon black pepper.
  12. Cover the dish with aluminum foil.
  13. Bake for 60-75 minutes, or until potatoes are tender.
  14. Remove foil, sprinkle 1 cup shredded Queso Añejo (or Romano) over the potatoes.
  15. Continue baking for 15-20 minutes, or until the liquid has thickened and the cheese is melted and bubbly.
  16. Let cool slightly before sprinkling with 1/4 cup fresh cilantro.
  17. Serve warm and enjoy!
