Ingredients
  

  • 4 cups thinly sliced sweet potatoes
  • 1/2 cup finely chopped onion
  • 1 medium jalapeño pepper, seeded and minced
  • 2 cloves garlic, minced
  • 2 tablespoons unsalted butter
  • 2 tablespoons all-purpose flour
  • 1 cup milk
  • 1/2 cup shredded Monterey Jack cheese
  • 1/2 cup shredded sharp cheddar cheese
  • 1 teaspoon smoked paprika
  • 1/2 teaspoon salt
  • 1/4 teaspoon black pepper
  • 1 tablespoon olive oil
  • Optional fresh cilantro or parsley for garnish

Instructions
 

  • Preheat your oven to 375°F (190°C). Lightly oil a baking dish large enough to hold a single layer of potatoes.
  • In a skillet, melt butter over medium heat. Add onion and jalapeño, sauté until softened and fragrant, about 3–4 minutes. Stir in garlic for another 30 seconds.
  • Sprinkle flour over the onions and peppers, stirring to form a light roux. Slowly whisk in milk, cooking until the mixture thickens into a creamy sauce.
  • Stir in half of the Monterey Jack and cheddar cheeses, letting them melt into the sauce. Season with paprika, salt, and pepper. Remove from heat.
  • Arrange a layer of sweet potatoes in the prepared dish. Pour a portion of the cheese sauce over the layer, then repeat with remaining potatoes and sauce to form 2–3 layers.
  • Top with the remaining cheese and drizzle olive oil over the surface. Cover loosely with foil.
  • Bake for 25–30 minutes covered, then remove foil and bake an additional 15–20 minutes until the potatoes are tender and the top is bubbling and golden.
  • Let the dish rest for about 5–10 minutes before slicing. Garnish with fresh cilantro or parsley if desired and serve warm.
