How to Make Croissant Bake Breakfast Casserole

Preheat your oven to 350°F (175°C). This establishes a warm environment for baking your masterpiece.
In a large bowl, whisk together the eggs, milk, salt, pepper, garlic powder, and onion powder until smooth. Take your time here—the more blended, the better!
Grease a 9×13-inch baking dish. This makes for cleaner servings and prevents sticking.
Layer the torn croissants across the bottom of the dish, creating a luscious, flaky bed.
Scatter the chopped deli meat and shredded cheese evenly over the croissants. Picture this—each bite will be bursting with flavor!
Pour the egg mixture over the layered ingredients, gently pressing down to absorb the flavors.
Allow the casserole to sit for 10-15 minutes. This wait allows the croissants to soak up the egg mixture, achieving that custard-like center.
Bake for 30-35 minutes, or until the egg is set and golden brown on top. The moment the aroma fills your kitchen, you’ll be counting down the seconds.
Let it cool for a few moments before serving. This gives the casserole time to firm up for easy slicing.

Chef’s Notes & Helpful Tips

Make-ahead tips: Assemble your casserole the night before, cover it tightly, and store it in the refrigerator. Simply pop it into the oven in the morning—less stress and more time to relax.
Cooking alternatives: If you have an air fryer, transform this into an irresistible individual casserole dish. Reduce the temperature and check for doneness regularly.
Customization ideas: Experiment with different breads like brioche for a sweeter touch, or try adding sautéed vegetables for extra nutrition.

Common Mistakes to Avoid

Undercooking or overcooking: Keep a close eye on the time and doneness. The casserole should be golden brown and the eggs fully set to achieve a perfect texture.
Skip the soaking time: Allowing the casserole to rest after assembling is critical; it prevents unsoaked, dry bits.
Forget to grease your dish: Don’t skip this step! A greased dish helps avoid a sticky situation when you’re serving.
