Ingredients

Cheddar Bay Biscuit Layer:

2 cups all-purpose flour
1 tbsp baking powder
1 tsp garlic powder
0.5 tsp salt
0.5 tsp sugar
0.5 cup unsalted butter, cold and cubed
1 cup shredded sharp cheddar cheese
0.75 cup milk

Egg Mixture:

8 large eggs
1 cup milk or half-and-half
0.5 tsp salt
0.25 tsp black pepper
1 tsp Dijon mustard (optional)
1 cup shredded cheddar cheese
0.5 cup diced cooked ham, bacon, or sausage (optional)
0.25 cup chopped green onions or fresh herbs (optional)

Topping (Optional):

2 tbsp melted butter
1 tsp garlic powder
1 tsp parsley, chopped

Instructions

Preheat oven: Set your oven to 375°F (190°C). Grease a 9×13-inch baking dish or line it with parchment paper.
Prepare biscuit layer: In a medium bowl, whisk together flour, baking powder, garlic powder, salt, and sugar. Cut in cold butter until the mixture resembles coarse crumbs. Stir in cheddar cheese and milk to form a sticky dough. Press into the prepared baking dish.
Bake biscuit base: Bake biscuits for 12–15 minutes until lightly golden. Remove from oven and allow to cool slightly.
Mix eggs: In a large bowl, whisk together eggs, milk, salt, pepper, and Dijon mustard if using. Stir in cheddar cheese, meat, and herbs.
Assemble casserole: Pour the egg mixture evenly over the baked biscuit layer. Ensure it spreads to fill gaps.
Bake casserole: Return to the oven and bake for 25–30 minutes or until eggs are fully set and top is lightly golden.
Add topping: If desired, mix melted butter with garlic powder and brush over the top. Sprinkle with chopped parsley for color.
Serve: Let cool for 5 minutes before slicing. Serve warm with fresh fruit, coffee, or juice for a complete brunch.

Tips for the Perfect Cheddar Bay Biscuit Egg Casserole

Don’t overmix the biscuit dough: Keeping the biscuits tender is key. Mix until just combined.
Use sharp cheddar: The stronger flavor balances the buttery biscuits perfectly.
Customize proteins: Ham, bacon, or sausage all work wonderfully. For a vegetarian version, add mushrooms, bell peppers, or spinach.
Advance prep: Assemble the casserole the night before and refrigerate overnight. Bake the next morning for effortless brunch.
Add creaminess: For a richer texture, replace milk with half-and-half in the egg mixture.

Variations to Try

Spicy Twist: Add diced jalapeños or a pinch of red pepper flakes to the egg mixture.
Herb Lover’s: Mix fresh rosemary, thyme, or chives into the biscuits for an aromatic flavor.
Cheese Explosion: Swap cheddar for a combination of cheddar, Monterey Jack, and Gruyère.
Mini Casseroles: Use ramekins to make individual servings perfect for meal prep or gifts.

Serving Suggestions

Pair with fresh fruit, a light salad, or roasted potatoes for a balanced brunch.
Serve with hot coffee, tea, or freshly squeezed orange juice for a classic breakfast feel.
Great for potlucks: slice into squares and serve warm or at room temperature.
