Step‑by‑Step Instructions for Overnight Croissant Breakfast Casserole
Step 1: Preheat and Prepare the Baking Dish
Preheat your oven to 350°F (175°C) and grab a 9×13-inch baking dish. Grease the dish generously with butter or cooking spray to ensure that the Overnight Croissant Breakfast Casserole slides out easily after baking. This step is key for a beautifully cooked casserole that maintains its shape.
Step 2: Whisk Together the Base Ingredients
In a large mixing bowl, whisk together 8 eggs, 2 cups of whole milk, 1 teaspoon of garlic powder, 1 teaspoon of salt, 1/2 teaspoon of black pepper, and 1 teaspoon of paprika. Mix until the mixture becomes frothy and bubbly—this will create a fluffy texture for the casserole. Set this egg mixture aside while you prepare the croissants and other ingredients.
Step 3: Combine the Croissants and Fillings
Roughly tear 6-8 croissants into bite-sized pieces and gently fold them into the egg mixture. Also, add in 1 to 2 cups of cooked sausage crumbles, 1 diced bell pepper, and 1 chopped onion. Be careful not to crush the croissants too much; you want to maintain their flaky texture throughout the Overnight Croissant Breakfast Casserole.
Step 4: Transfer to the Baking Dish
Pour the croissant and egg mixture into the greased baking dish, spreading it evenly across the bottom. Ensure that the mixture is well-distributed to give every bite its delicious flavor. After spreading, sprinkle 1 to 2 cups of shredded cheddar cheese generously over the top for a gooey, cheesy finish once baked.
Step 5: Cover and Refrigerate Overnight
Once assembled, cover the dish tightly with plastic wrap and place it in the refrigerator. Allow the casserole to chill for at least 4 hours, but overnight is preferable. This soaking time allows the croissants to absorb the custard, enhancing the flavor and creating a delightful texture in the Overnight Croissant Breakfast Casserole.
Step 6: Bring to Room Temperature and Bake
Before baking, remove the casserole from the refrigerator and let it sit at room temperature for about 15 minutes. This helps with even cooking. Bake uncovered in your preheated oven for 35-40 minutes or until the top is golden brown, and the center is firm to the touch. The casserole should look invitingly puffy and fragrant.
Step 7: Cool, Garnish, and Serve
Allow the Overnight Croissant Breakfast Casserole to cool for about 5 minutes after baking. This short resting time makes it easier to cut. Serve warm, garnished with a sprinkle of fresh parsley for a touch of color and a burst of flavor. Enjoy this cozy breakfast delight that’s perfect for any occasion!
