How the Recipe Comes Together

The beauty of this bake is how little active time it needs. Brown your ground beef in a skillet, drain off any extra fat, then stir in marinara sauce, Italian seasoning, salt, and pepper until everything smells like a pizza parlor. Fold in the cauliflower rice and half the mozzarella, then spread that mixture into your baking dish.

Top with the remaining mozzarella and a generous layer of pepperoni slices, then slide it into a 350°F oven for 25 to 30 minutes. You’re looking for bubbly, golden cheese and edges that just start to brown.

Note: Let the casserole rest for five minutes after pulling it from the ovenit firms up slightly and makes serving much cleaner.
