Before anything else, get the sausage browned in your skillet. You want it cooked through and crumbled so every bite has savory pork goodness. Once done, drain any excess grease so the final dip isn’t too oily.
In a mixing bowl, combine the softened cream cheese, mayonnaise, 1 cup of shredded cheddar, Monterey Jack, jalapeños, and garlic. Stir until everything is melded together, then fold in the cooked sausage gently so it’s evenly distributed.
Take each biscuit half and roll it into a ball, forming a ring around the edge of your skillet or baking dish. The dough should touch so it bakes into a soft, pull-apart bread that’s perfect for dipping.
Spoon the sausage and cheese mixture into the center of the ring. Sprinkle the remaining shredded cheddar on top so it bubbles up and browns.
Brush the biscuit ring with beaten egg mixed with water and sprinkle with a pinch of salt. Bake at 350°F for 25–30 minutes or until the biscuits are golden and the dip is hot. Finish with sliced green onions before serving.
