How to Make It
Step 1
Preheat oven to 375°F. Split each raw biscuit in half. Arrange 12 halves in an even layer in bottom of a lightly greased 13- x 9-inch baking dish, and lightly press together. Bake in preheated oven until partially cooked and lightly golden, about 8 minutes. Reduce oven temperature to 350°F.
Step 2
Top baked biscuits evenly with ham, and sprinkle with cheeses. Whisk together eggs, milk, mustard, salt, and pepper in a medium bowl until combined. Pour egg mixture evenly over ham and cheese.
Step 3
Cut remaining biscuit halves in half, and line them along sides of baking dish. Cover with aluminum foil, and bake at 350°F until egg mixture is set, 45 to 50 minutes. Let stand 10 minutes. Sprinkle with chives, and drizzle with mustard.
