Step‑by‑Step Instructions for Sausage Croissant Breakfast Casserole
Step 1: Prep Croissants
Preheat your oven to 375°F (190°C). While it’s heating, take your flaky croissants and slice them in half lengthwise before cutting them into 1-2 inch cubes. Grease a 9×13 casserole dish generously and layer the croissant cubes evenly across the bottom, making sure to cover the surface well to create a buttery base for your Sausage Croissant Breakfast Casserole.
Step 2: Cook Sausage
In a skillet over medium heat, crumble and brown the classic breakfast sausage until it’s no longer pink, about 5-7 minutes. Once cooked, add finely chopped shallots and minced garlic, sautéing for an additional 2-3 minutes until the shallots are soft and fragrant. After cooking, cool slightly and drain any excess grease for a balanced, savory flavor.
Step 3: Mix Egg Mixture
In a large mixing bowl, whisk together six eggs with 2 cups of milk and 1 cup of half-and-half until fully combined. Then, add a sprinkle of salt, pepper, and Dijon mustard, mixing well to incorporate. Finally, fold in two-thirds of your chosen cheeses, ensuring they’re evenly distributed—this custard will provide the creamy richness your Sausage Croissant Breakfast Casserole needs.
Step 4: Assemble Casserole
Spread the cooked sausage mixture evenly over the cubed croissants in the casserole dish. Pour the prepared egg mixture gently over the top, ensuring every croissant piece is well-coated. Using a spatula, gently toss the mixture to combine everything, making sure the croissants absorb the custard mixture for that delicious, soft texture as it bakes.
Step 5: Bake
Sprinkle the remaining cheese over the top of the assembled casserole, creating a gooey, cheesy layer. Cover the dish with aluminum foil and place it in the preheated oven to bake for 35 minutes. After this time, remove the foil and continue baking for an additional 5 minutes to allow the cheese to bubble and turn a beautiful golden brown on top.
Step 6: Cool & Serve
Once baked, remove the cheese-filled Sausage Croissant Breakfast Casserole from the oven and let it cool for about 5 minutes before serving. For an added touch of freshness, garnish with chopped green onions. Cut into squares and serve warm, allowing everyone to enjoy this comforting, delicious breakfast delight.
