What Makes This Recipe Great
Looking for a breakfast dish that feels fancy but requires minimal effort? This Ham and Cheese Croissant Bake is the answer. By using store-bought mini croissants, you get a buttery, flaky texture that elevates a standard egg casserole into something truly gourmet. With caramelized onions, sharp Gruyère, and savory ham, it’s the perfect centerpiece for a holiday brunch or a lazy Sunday morning.
Ingredient Information

- Mini Crossants– If you can’t find croissants, a loaf of brioche or challah torn into cubes works as a great substitute.
- Ham– Swap the ham for sautéed mushrooms or sun-dried tomatoes for a savory veggie version.
- Onion– Chopped and caramelized for a deep, rich flavor.
- Chives– Adds a bright, herbal pop
- Swiss Cheese– Shredded for that classic melt
- Gruyere Cheese– Don’t have Gruyère? Sharp white cheddar or even fontina are excellent melting alternatives
- Eggs– The protein-packed custard base
- Whole Milk– any milk preference will work for this recipe
- Dijon– Adds a subtle tang
- Stone Ground Mustard– Provides texture and a bit of “zip.”
Step By Step
- Grease a 9×13 baking dish. Preheat your oven to 375°F.
- Tear the croissants into large chunks. Layer half in the dish, followed by the ham, sautéed onions, and half of the cheese blend. Top with the remaining croissants.
- In a large bowl, whisk the eggs, milk, mustards, 2 tbsp chives, salt, and pepper.
- Evenly pour the mixture over the croissants. Press down lightly to submerge. Top with the remaining cheese.
- Cover with foil and bake for 25 minutes. Remove foil and bake for another 25 minutes until the cheese is bubbly and the top is golden brown.
- Once removed from the oven, top with remaining chives.

This savory bake is versatile and pairs well with several sides:
- Light & Fresh: Serve alongside a crisp arugula salad with a simple lemon vinaigrette to cut through the richness of the cheese.
- The Brunch Spread: Pair it with a fresh fruit platter and a round of mimosas or spicy bloody marys.
- Sweet & Savory: Add a side of maple-glazed bacon or a small bowl of Greek yogurt topped with honey and berries for a balanced meal.
