🧰 Equipment Needed

Before you get started, gather these kitchen basics:

• 9×13-inch baking dish
• Large skillet
• Mixing bowls
• Whisk
• Measuring cups and spoons
• Spatula
• Oven mitts

🛒 Ingredients

🥩 Viandes:

• 1 lb breakfast sausage, ground (pork or turkey)

🧄 Fruits et légumes:

• ½ medium onion, finely chopped
• 1 tsp dried oregano

🥚 Produits frais:

• 5 large eggs

🧴 Condiments:

• 1½ cups prepared country gravy (store-bought or homemade)

🧂 Aides culinaires et épices:

• 10 oz refrigerated biscuit dough, cut into pieces (about 1 standard can)

🧈 Produits laitiers:

• 2 tbsp butter
• 1½ cups cheddar cheese, shredded
• ½ cup whole milk

Optional: Use pepper jack or a cheese blend for extra flavor!

👩‍🍳 Directions

Step 1: Preheat Oven

Preheat your oven to 375°F (190°C). Grease a 9×13-inch baking dish with butter or nonstick spray.

Step 2: Cook the Sausage Mixture

In a large skillet over medium heat:

• Add 1 lb breakfast sausage and ½ chopped onion. Cook until browned and crumbly (about 6–8 minutes).
• Stir in 1 tsp oregano for a herbaceous boost.
• Drain any excess grease and set aside.

Step 3: Prepare the Biscuits

Cut 10 oz refrigerated biscuit dough into quarters (bite-sized pieces).

Spread the pieces evenly across the bottom of the greased baking dish.

Step 4: Whisk the Eggs

In a medium mixing bowl, whisk together:

• 5 eggs
• ½ cup whole milk

Season lightly with salt and pepper, if desired.

Step 5: Layer the Casserole

Layer as follows:

1. Biscuit pieces on the bottom
2. Sausage and onion mixture evenly over biscuits
3. Pour egg mixture across the top
4. Drizzle 1½ cups country gravy over everything
5. Sprinkle 1½ cups cheddar cheese on top

Optional: Add extra gravy or cheese on top for a gooier, cheesier finish.

Step 6: Bake

Bake uncovered at 375°F for 30–35 minutes, or until the biscuits are cooked through and the cheese is melted and golden.

To check doneness, insert a knife into the center — it should come out clean with no raw egg.

Step 7: Rest & Serve

Let the casserole rest for 5 minutes before slicing. This helps everything firm up and makes it easier to serve.

Serve with hot sauce, more gravy, or a side of fresh fruit for a balanced brunch plate.
