Twenty years ago, I adapted my grandma’s Midwest egg bake into what I now call Croissant Breakfast Casserole. In just 100 words, here’s the condensed version: Tear buttery croissants into bite-sized pieces and layer them with savory sausage and shredded cheese. Whisk together eggs, milk, Dijon, salt, and pepper; pour evenly over the croissants. Let it soak overnight in the fridge. Next morning, bake at 350°F for 45–50 minutes until golden and puffed. Serve warm. This Croissant Breakfast Casserole combines ease, flavor, and heartiness, making it perfect for brunch type foods, hot breakfast for a crowd, or any large gathering breakfast ideas.
