Cheesy Garlic Egg Croissant Bake

This cheesy garlic egg croissant bake is my answer to mornings when you want something indulgent but easy enough to pull off before coffee kicks in. Crisp, buttery croissants get soaked in a creamy, garlicky egg custard, then buried under a blanket of gooey cheese and baked to golden perfection. It is the ultimate make-ahead breakfast treat for holidays, brunches or anytime you want your table to stop and stare.

The first time I made this my kitchen smelled like a French bakery. Everyone circled the oven and there were no leftovers. It is still my family’s top request whenever overnight guests come.

Ingredients

• Croissants: The backbone that delivers flaky layers use day-old croissants for better absorption and richer flavor seek out bakery croissants for that deep buttery flavor
• Eggs: Create structure and creaminess always use fresh eggs with rich yolks for best results
• Whole milk and heavy cream: Form a rich custard base opt for good dairy for that extra creamy texture
• Cheddar cheese: Adds sharpness a good block of sharp cheddar melts better than pre-shredded
• Mozzarella cheese: Brings stretchy melt and an extra gooey bite go for whole milk mozzarella if you can
• Parmesan cheese: For salty depth and a golden top freshly grated makes all the difference in flavor
• Garlic: Infuses warmth and aroma always mince fresh cloves for that punchy kick
• Fresh chives or parsley: Brighten and balance the richness grab the brightest herbs at the store
• Salt and black pepper: To season every layer freshly cracked pepper adds subtle heat
• Dried thyme (optional): For a hint of earthy flavor

Instructions

Prepare the Oven and Pan:

Preheat your oven to 350 degrees Fahrenheit or 175 degrees Celsius Grease a nine by thirteen baking dish with butter or nonstick spray to prevent sticking and add flavor

Layer the Croissants:

Arrange your torn croissant pieces evenly across the prepared baking dish Press them in lightly so they form a rustic bed for the custard

Mix the Custard:

In a large mixing bowl whisk together eggs whole milk heavy cream minced garlic chives or parsley salt black pepper and dried thyme if using Whisk thoroughly for at least one minute so the custard becomes light and aerated

Add Cheese:

Stir in the shredded cheddar mozzarella and half of the grated Parmesan cheese Fold them through so every bite is dotted with cheese

Soak the Croissants:

Pour your egg mixture evenly over the croissant bed Gently press down the croissants with your hands or a spatula making certain they are all moistened and begin drinking up the custard

Add Butter and More Cheese:

Drizzle the melted butter gently across the top of the casserole This will ensure a crisp golden crown Sprinkle the remaining Parmesan evenly for a savory finish

Let it Rest:

Let the unbaked casserole sit for ten minutes so every croissant chunk soaks and softens This waiting step is key for even texture

Bake to Perfection:

Bake on the center rack for thirty to thirty five minutes Watch for the top to become golden and the center to puff slightly The custard should be just set with no visible liquid in the center

Cool and Garnish:

Let the casserole cool for five minutes out of the oven so it slices clean Sprinkle with extra fresh herbs right before serving for a pretty and fresh finish

Cool the casserole completely before refrigerating Leftovers keep well in an airtight container for up to three days For best results reheat slices gently in the oven to restore their crisp edges Avoid microwaving for too long or the custard may turn rubbery
