🧡 Why This Breakfast Casserole Stands Out

From busy weekday mornings to laid-back Sunday brunches, this casserole meets the moment with flavor, ease, and versatility.
🧀 What Makes Cheddar Biscuits So Special?
The heart of this recipe lies in the biscuits. Unlike plain dough or hash browns, Cheddar Bay-style biscuits bring a buttery, garlicky, cheesy bite to every forkful. These biscuits are soft, slightly crisp on the edges, and melt in your mouth when baked into an egg mixture.
When soaked in seasoned eggs, the biscuits puff up beautifully, absorbing flavor without becoming mushy. It’s like enjoying the comfort of a Southern-style breakfast with the richness of a restaurant-quality bake.
