Ingredients You Need for This:

This Croissant Breakfast Casserole ingredient list is SHORT but mighty! Here’s what you need to turn your breakfast into an unforgettable flavor fiesta:
- 6 large eggs – The backbone of your cheesy egg bake
- 2 cups whole milk – For that creamy custard texture
- 4 cups torn croissant pieces (about 6 large croissants) – The star croissant baking recipe twist that soaks up every drop of flavor
- 2 cups diced cooked ham – Keeps this ham and cheese casserole seriously satisfying
- 2 cups shredded sharp cheddar cheese – Sharp for bold flavor punch
- 1/2 cup diced onions – Adds just the right bite
- 1/2 teaspoon smoked paprika – A little smoky magic
- Salt and pepper to taste – Always essential
- 1 tablespoon Dijon mustard – Game changer for depth
The secret to epic Croissant Breakfast Casserole is using real butter croissants instead of plain bread—trust me, that buttery flakiness soaks up egg custard like a dream. For the best results, find fresh bakery croissants or check the frozen section. Quality croissants make all the difference.
Splurge on sharp cheddar cheese for this Croissant Breakfast Casserole. It melts perfectly and adds that bold tang your mornings deserve. On a budget? Colby or Monterey Jack still deliver the melty goodness without breaking the bank.
Keep your diced ham and onions prepped up—it’s a make ahead breakfast dream come true. Chop and store in airtight containers to save precious morning minutes. Use leftover or store-bought ham; just avoid anything too salty.
Step-by-Step Instructions:
- Preheat your oven to 350°F (175°C). Don’t stress—your Croissant Breakfast Casserole is going to be incredible from the start.
- Tear croissants into bite-sized pieces. The fluffy crumbs are your casserole’s secret weapon.
- Whisk together eggs, milk, Dijon mustard, smoked paprika, salt, and pepper. Pro tip for Croissant Breakfast Casserole perfection: whisk until mixture looks smooth and slightly frothy—that’s your cheesy egg bake base engaging.
- In a large greased baking dish, layer half of croissant pieces. Scatter half of diced ham, onions, and shredded cheddar over the top.
- Repeat with remaining croissants, ham, onions, and cheese. This layering traps flavors so every bite pops.
- Pour egg mixture slowly over layers letting the custard soak through the croissants. Pause to press croissant bits lightly with a spatula ensuring even absorption.
- Cover with foil and bake for 35 minutes. Your kitchen will start smelling like brunch goals in 10 minutes. This is where your Croissant Breakfast Casserole transforms into pure magic.
- Remove foil and bake uncovered for another 15-20 minutes until the top turns golden, cheese bubbles, and the edges crisp.
- Check doneness by inserting a toothpick in the center; it should come out clean, and the casserole should feel set without being rubbery.
- Let it rest 10 minutes before slicing. This holds the gooey goodness so every piece stays perfect.
Here’s where most people mess up their Croissant Breakfast Casserole—they rush or don’t press the egg soak in well. Giving croissants time to absorb makes all the difference. While it bakes, grab your camera for Instagram gold because this cheesy egg bake looks as good as it tastes!
