👩🍳 Instructions
Step 1: Preheat and Prepare
Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish or line with parchment paper.
Step 2: Cook the Sausage
In a skillet over medium heat, cook the breakfast sausage until browned and crumbled. Drain any excess grease.
Step 3: Cut the Biscuits
Open the biscuit dough and cut each biscuit into quarters. Spread evenly across the bottom of your baking dish.
Step 4: Whisk the Eggs
In a bowl, whisk together the eggs, milk, garlic powder, onion powder, salt, and pepper.
Step 5: Layer It Up
Sprinkle the cooked sausage over the biscuit pieces. Pour the egg mixture on top. Sprinkle with shredded cheese.
Step 6: Bake
Bake for 25–30 minutes, or until the eggs are set and the biscuits are golden. Check the center with a toothpick—it should come out clean.
Step 7: Garnish and Serve
Top with green onions, extra cheese, or a drizzle of hot sauce. Serve warm!
