  • 1 lb antibiotic-hormone-free ground beef
  • 4 oz cremini mushroom caps, finely chopped
  • 1 tsp steak seasoning
  • 1/2 tsp freshly ground black pepper
  • Salt as needed
  • 2 tbsp ghee
  • 1 large organic onion, halved and thinly sliced
  • 1 organic red bell pepper, cut into strips
  • 1 organic green bell pepper, cut into strips
  • 2 cloves organic garlic, finely minced
  • 8 slices Trader Joe's Goat's Milk Dutch cheese

Bread Topping

  • 2 large eggs
  • 1 cup coconut milk creamer
  • 1 tbsp olive oil
  • 1/2 cup sweet white rice flour
  • 1/2 cup millet flour
  • 2 tsp guar gum
  • 1/2 tsp salt


  1. Wash and prep all the vegetables. Usually the mushrooms are washed under filtered water then wiped with a paper towel before chopping.
  2. Preheat the oven to 400 degree F.
  3. Add the ground beef, chopped mushrooms, steak seasoning, and freshly ground black pepper to a large skillet and cook over medium high heat. Stir with a wooden spoon to break up the meat until the meat is cooked through, about 8 minutes. Drain off any excess fat. Transfer to either a 13x9 or deep dish 9x9 casserole baking dish. Taste to see if it needs any more salt.

  4. Wipe down the skillet and then add the ghee to the skillet and melt over medium-high heat. Add the onion, bell peppers and garlic with and a pinch of salt. Cook for about 5 minutes, stirring often. Remove from heat and set aside.
  5. Prepare the bread topping by whisking the eggs, coconut milk and olive oil together in a medium size bowl (or 2-cup measuring glass). Add the flours, guar gum and salt to the liquid mixture and stir until well combined.

  6. Next assemble the casserole. Add the onion and pepper mixture over the meat in the casserole dish.  Add the cheese slices on top of the veggies, layering the cheese over each other slices if necessary. Pour the bread topping next.  Place the casserole dish in the oven and bake for about 30 minutes. 

  7. Let sit for a few minutes after pulling it from the oven before serving. Enjoy!
