serves 4 generously
1 lb baby gold potatoes, halved or quartered into bite-size pieces
1 small-medium poblano pepper, seeded, trimmed, and cut into 1/4-inch dice
1 12-oz can whole tomatillos, drained (about 4-5 small whole tomatillos)
1/2 cup full-fat coconut milk
1 serrano pepper, trimmed and seeded, roughly chopped
1 small-medium clove garlic
1/2 tsp fine sea or kosher salt
1/4 tsp ground coriander
Heat oven to 425.
Lay the chopped potatoes in one layer in a baking dish that fits them fairly snugly. Sprinkle the chopped poblano over, keeping them toward the center and away from the edges of the dish.
Use a small food processor or immersion blender to blend the tomatillos, coconut milk, serrano pepper, garlic, salt, and coriander. Pour slowly and evenly over potatoes.
Bake 55 minutes, or until potatoes are browned, tender, and the sauce is thickened and bubbling. Let cool five minutes before serving.
