Breakfast Biscuit Casserole

Ingredients

2 tbsp unsalted butter (for sautéing the onions)
½ onion, diced (adds a little sweetness and depth of flavor)
10 oz refrigerated biscuit dough, cut into 2-inch pieces (use store-bought for convenience or homemade if preferred)
½ cup whole milk or heavy cream (makes the eggs extra creamy)
5 eggs (provides the rich, fluffy base)
1 tsp oregano (adds a touch of herbal warmth)
1½ cups shredded cheddar cheese (melts beautifully and adds sharp, creamy flavor)
1 lb breakfast sausage (regular, spicy, or turkey sausage all work great)
1½ cups prepared country gravy (use a gravy mix packet for ease or homemade for a more traditional touch)

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

Directions

Preheat the Oven: Preheat your oven to 350°F. Grease a 9×13-inch baking dish with cooking spray or butter to prevent sticking.
Sauté the Onions: In a skillet over medium heat, melt the butter. Add the diced onion and sauté for 3-4 minutes, until softened and slightly caramelized. Set the onions aside.
Cook the Sausage: In the same skillet, cook the breakfast sausage over medium heat, breaking it apart with a spoon as it cooks. Once browned and fully cooked, drain any excess grease and set the sausage aside.
Prepare the Biscuits: Cut the refrigerated biscuit dough into 2-inch pieces. You can either use store-bought dough or make your own for a more homemade touch.
Mix the Eggs and Cream: In a bowl, whisk together the eggs, whole milk (or heavy cream), oregano, and a pinch of salt and pepper. Mix well until the eggs are well-beaten and combined with the cream.
Assemble the Casserole: In the prepared baking dish, layer the biscuit pieces evenly on the bottom. Then, top with the sautéed onions, cooked sausage, and 1 cup of shredded cheddar cheese. Pour the egg mixture over the top, making sure it evenly coats the biscuits.
Top with Gravy and Cheese: Spoon the prepared country gravy over the casserole. Sprinkle the remaining ½ cup of shredded cheddar cheese on top.
Bake: Place the baking dish in the oven and bake for 30-35 minutes, or until the casserole is set and the top is golden brown and bubbly.
Serve: Allow the casserole to cool for a few minutes before serving. Cut into squares and enjoy!
