  • Total Time: 1 hour
  • Yield: 8 servings

Ingredients

Biscuit Dough

  • 2 ½ cups (312.5 g) all-purpose flour
  • 4 teaspoons baking powder
  • 1 tablespoon granulated sugar
  • 2 teaspoons kosher salt
  • 2 cups (490 g) buttermilk, room temperature
  • ½ cup (113 g) unsalted butter, melted

Casserole

  • 1 pound turkey sausage
  • ½ cup diced yellow onion
  • 10 large eggs, room temperature
  • ½ cup (122.5 g) whole milk, room temperature
  • ½ teaspoon kosher salt
  • ½ teaspoon black pepper
  • 2 cups (226 g) mild cheddar cheese, shredded
  • 1 cup (113 g) mozzarella cheese, shredded
  • Parsley, optional for garnish

Instructions

  1. Preheat Oven and Prepare Dish: Preheat your oven to 375°F (190°C) and lightly spray a 9×13-inch baking dish with cooking spray to prevent sticking.
  2. Make the Biscuit Dough: In a medium bowl, whisk together the all-purpose flour, baking powder, sugar, and kosher salt until evenly combined. Pour in the buttermilk and stir gently until mostly combined, being careful not to overmix to maintain biscuit tenderness. Pour the melted unsalted butter into the prepared baking dish, then evenly spread the biscuit dough over the butter using a spatula or your hands for an even base layer.
  3. Cook the Turkey Sausage and Onions: Heat a large skillet over medium heat and add the turkey sausage and diced yellow onions. Cook them together for 6 to 8 minutes, stirring occasionally, until the sausage is browned and fully cooked and the onions are softened. Drain any excess liquid from the skillet to avoid sogginess, then distribute the sausage and onion mixture evenly over the biscuit dough in the baking dish.
  4. Prepare Egg and Cheese Mixture: In a large bowl, whisk together the ten large eggs, whole milk, kosher salt, and black pepper until smooth. Gently fold in the shredded cheddar and mozzarella cheeses, mixing just enough to combine evenly. Pour this rich egg and cheese mixture over the turkey sausage layer, ensuring a uniform layer for even baking.
  5. Bake the Casserole: Place the baking dish in the preheated oven and bake for approximately 40 minutes, or until a knife inserted in the center comes out clean, indicating the casserole is fully set and cooked through.
  6. Rest and Garnish: Remove the casserole from the oven and allow it to rest for 10 minutes. This resting time lets the butter soak fully into the biscuits, enhancing flavor and texture. Garnish with fresh parsley if desired before slicing and serving the bake warm.

Notes

  • Use room temperature eggs, milk, and buttermilk to ensure even mixing and better texture in the custard layer.
  • Do not overmix biscuit dough to keep the biscuits tender and flaky.
  • Drain cooked sausage to avoid a watery casserole base.
  • Letting the bake rest before serving enhances butter absorption and flavor.
  • Optional garnish with parsley adds a fresh visual and flavor contrast.
