  • casserole dish
  • oven


  • 2 pounds ground beef , preferably pasture-raised
  • 3 small onions , diced, or 2 large (OR less, for stricter Keto, depending on personal preference)
  • 1 cup water , filtered
  • 14 ounces (or about 1-1/2 cups) red salsa , fresh pico de gallo or jarred (homemade or store-bought)
  • 8 ounces cheese , grated (aged cheddar)
  • 8 ounces whole green chilies , canned, cut along one line and opened so they can be splayed (For GAPS, okay to roast green bell peppers.)
  • 8 ounces diced green chilies , canned (For GAPS, okay to dice green bell peppers.)
  • 1 7-ounce jar tomato paste
  • 1/3 cup coconut flour ; for Paleo/fruit-free version 2/3 cup cassava flour also works
  • 1 Tablespoon apple cider vinegar or 1 teaspoon cream of tartar
  • 2 teaspoons sea salt
  • 2 teaspoons dried oregano
  • 2 teaspoons cumin
  • 1 teaspoon baking soda , sifted
  • fresh cilantro , minced, for garnish
  • freshly ground pepper to taste


  • Preheat oven to 375 degrees Fahrenheit. Grease a large casserole dish, like a 9" by 13".
  • In medium size bowl combine salsa, tomato paste and cumin, stirring well. Measure out 1 cup. Set aside.
  • Combine in small bowl: coconut flour, baking soda and optional cream of tartar. Set aside.
  • In large mixing bowl add the following: raw beef, water, the 1 cup portion of thickened salsa, onions, diced green chilies, apple cider vinegar, oregano, sea salt and pepper. Mix well.
  • Add the coconut flour mixture to the large mixing bowl, and stir well again.
  • Spread meat mixture into greased casserole. Top with remaining salsa. Lay whole green chilies (spread out) over the surface.
  • Bake in preheated oven about 45 minutes, until bubbly around edges and slightly puffed all over. Remove from oven.
  • Top casserole with grated cheese. Return casserole to hot oven for 10 minutes, until cheese is well melted, but not crispy (it should be soft and creamy on top).
  • Serve with salad, sour cream and olives. Top with fresh cilantro.
