Recipe Directions for Sausage Croissant French Toast Casserole

Making this Sausage Croissant French Toast Casserole is a breeze, and the process is just as enjoyable as the final product. Follow these steps to create a hearty dish that’s perfect for breakfast or brunch. Let’s get started!
- First, heat your oven to 400 degrees Fahrenheit. This is important because you want to toast the croissants until they’re golden brown. Spread the croissants on a large baking sheet, cut side up, and toast them for about 5 minutes. Keep an eye on them to prevent burning; they should be beautifully golden and fragrant.
- Once toasted, remove the croissants from the oven and let them cool. When cool enough to handle, tear them into large bite-size pieces. This step not only helps with texture but also ensures they soak up the custard perfectly.
- In a skillet, heat the olive oil over medium heat. Add the sliced scallions and the Italian sausage. Cook, breaking the sausage apart with a spatula, until it’s browned and crumbled, which should take about 5 minutes. The goal is to cook it until it’s nice and crumbled, blending the flavors with the scallions.
- Once the sausage is cooked, stir in the sage, and then remove the skillet from the heat. The warmth will release the flavors of the sage, enhancing the mixture even more.
- In a large mixing bowl, toss the pieces of croissant along with the sausage and scallion mixture until well combined. This will ensure that each piece is filled with flavor.
- In a separate bowl, whisk together the eggs, whole milk, and heavy cream until smooth. This mixture will serve as the custard that binds the casserole together. Then mix in 1½ cups of the Gruyère cheese, along with kosher salt and black pepper.
- Now it’s time to combine everything. Pour the custard mixture over the croissant and sausage mixture in the large bowl, ensuring everything is evenly coated.
- Prepare a 9 x 13-inch baking dish by coating it with non-stick cooking spray. Transfer the croissant mixture into the pan, spreading it out evenly for even cooking.
- Cover the dish with plastic wrap and refrigerate for at least 4 hours or overnight. This allows the croissants to soak up the custard fully, ensuring a rich texture.
- When you’re ready to bake, preheat the oven to 350 degrees Fahrenheit. Remove the plastic wrap and sprinkle the remaining Gruyère cheese over the top of the casserole. This step is crucial for that cheesy, bubbly topping we all love.
- Now, bake the casserole in the oven for about 45 minutes, or until it’s golden brown and set. You’ll know it’s done when it looks puffy and golden. Let it stand for about 10 minutes before serving, allowing the flavors to settle.
