Ingredients

  • 1 tablespoon butter
  • 2 tablespoons flour
  • 3/4 cup tomatillo, coarsely chopped (green tomatoes)
  • 1/2 cup onion, coarsely chopped
  • 2 poblano peppers, coarsely chopped (or sub in jalapeno for less heat)
  • 1/4 cup fresh cilantro, packed coarsely chopped, plus 2 TBSP leaves for garnish
  • 1/2 cup reduced-sodium chicken broth
  • 3/4 cup sour cream, divided (I used Light Sour Cream)
  • kosher salt
  • 1 tablespoon lime juice
  • 1 3/4 1 3/4 lbs salmon fillets (about 1 inch thick) or 1 3/4 lbs mahi mahi (about 1 inch thick)

Method

  • Preheat oven to 375. In a large frying pan, melt butter over high heat. Stir in flour, remove from heat, and mix to form a smooth paste.
  • Scrape flour paste into a blender. Add tomatillos, onion, chilies, chopped cilantro, chicken broth, and 1/2 cup sour cream. Puree in blender. Pour green sauce back into frying pan; add salt and lime juice to taste and bring to a boil.
  • Rinse fish, pat dry with paper towels, cut into 6 equal pieces, and season with salt. Set pieces slightly apart in an 8 by 12 in baking dish.
  • Pour evenly over fish.
  • Bake fish until it flakes but still looks moist in the center of the thickest part (cut to test), 15 to 20 minutes.
  • Serve up fish and spoon sauce over portions. Top off with small spoonfuls of remaining sour cream, and sprinkle with cilantro leaves.
