Step‑by‑Step Instructions for Pioneer Woman Overnight Breakfast Casserole
Step 1: Cook Meats
In a large skillet over medium heat, brown 1 pound of breakfast sausage for about 5-7 minutes, breaking it into crumbles until fully cooked. In the same skillet, add 6 slices of bacon and cook for another 5-6 minutes until crispy. Set aside half of the bacon for topping the casserole while draining excess fat from both meats.
Step 2: Layer Ingredients
Grease a 9×13 inch baking dish with cooking spray or butter. Layer the bottom with about 3 cups of thawed shredded potatoes, ensuring they cover the base evenly. Next, sprinkle the cooked sausage evenly over the potatoes, followed by half of the shredded cheddar cheese. This layered structure serves as the delicious foundation of your Pioneer Woman overnight breakfast casserole.
Step 3: Prepare Custard
In a mixing bowl, whisk together 6 large eggs and 2 cups of milk until well combined. Add 2 tablespoons of Dijon mustard, along with salt and pepper to taste, mixing until smooth. This custard mixture will bring everything together, giving your casserole a rich, creamy texture once baked.
Step 4: Assemble Casserole
Pour the egg and milk custard evenly over the layered ingredients in the baking dish. Make sure it seeps down into all layers for even cooking. Top with the remaining shredded cheddar cheese and crumble the reserved bacon on top for an added crunch. This final assembly creates a beautiful, attractive dish ready for the refrigerator.
Step 5: Chill
Cover the baking dish tightly with plastic wrap or aluminum foil, and refrigerate the casserole overnight. If you’re short on time, let it chill for at least 4 hours. This chilling time allows the flavors of the Pioneer Woman overnight breakfast casserole to meld beautifully, ensuring a satisfying dish to bake in the morning.
Step 6: Bake
Preheat your oven to 350°F (175°C). Once heated, remove the cover from the casserole and bake in the oven for 45-55 minutes, until golden brown and set in the center. An instant-read thermometer should register an internal temperature of 160°F, signifying it’s ready to serve.
Step 7: Serve
Remove the casserole from the oven and let it cool for a few minutes before cutting it into squares. Serve warm, garnished with freshly chopped green onions for a pop of color and added flavor.
