How to Make Croissant Casserole Step-by-Step
- Preheat your oven to 350°F and lightly grease a baking dish to prevent sticking.
- Cook the bacon until crispy, then drain it on paper towels before chopping it into bite-sized pieces.
- Sprinkle the bacon evenly into the baking dish, followed by the Gruyere and white Cheddar cheeses.
- Tear or slice the croissants into large pieces and arrange them evenly over the bacon and cheese.
- In a large bowl, whisk together the eggs, whole milk, heavy cream, Dijon mustard, chopped sage, salt, and pepper until smooth.
- Slowly pour the custard mixture over the croissants, making sure every piece is coated. Let it sit for several minutes so the croissants absorb the liquid.
- Bake for about 40–45 minutes, or until the casserole is puffed, golden brown, and the center is fully set.
- Garnish with freshly chopped chives before serving warm.
