Instructions
Step 1: Preheat the oven to 350°F.
Grease the 9 x13 casserole dish with 1 tablespoon of olive oil and set aside.
In a medium bowl, combine the ground beef, 1 tablespoon worcestershire sauce, 1 teaspoon onion powder, 1 teaspoon garlic powder, ¼ teaspoon black pepper, 1 ½ teaspoon sea salt, 1 tablespoon dehydrated onions, 2 eggs, ¼ c heavy cream and ¼ c coconut flour. Mix the ingredients with your hands until fully combined.
Step 2: Press the ground beef mixture into the bottom of the casserole dish and top with ½ c cheddar cheese evenly over the meat casserole. Bake for 20-30 minutes until the meat mixture is no longer pink and the internal temperature is 160°F.
Step 3: Make your special sauce by combining ½ c mayo, 3 tablespoon sugar-free ketchup, 2 tablespoon dill pickle relish, finely chopped pickle slices, 1 ½ tablespoon yellow mustard, 2 tablespoon grated or finely chopped white onion, ¼ teaspoon paprika, ¼ teaspoon onion powder, ¼ teaspoon garlic powder and 2 teaspoon pickle brine in a small bowl, set aside.

Hint: You may have some liquid run off from the juicy ground beef once it has cooked. I personally leave it for the extra fat and goodness. You can also drain it off before adding your toppings and homemade big mac sauce!
