Brown ground beef and drain. Return to oven safe skillet or pour into a greased baking dish.
Mix together eggs, cream, mayo, onion powder, salt and pepper, and 3/4 of the grated cheddar cheese. Pour this over the cooked, ground beef.
Sprinkle remaining grated, cheddar cheese over the meat mixture and pop into a preheated 350 degree oven for 30 minutes or until bubbling around edges.
Remove from oven and let stand for 10 minutes, then server. Enjoy!
