Ingredients

• 4 large butter croissants (preferably day-old), cut into 2-inch pieces
• 2 cups shredded Swiss cheese
• 1 ½ cups whole milk
• ½ cup heavy cream
• 8 oz (225 g) cooked ham, diced
• 4 green onions, thinly sliced
• 4 large eggs
• ½ tsp Dijon mustard
• ½ tsp freshly ground black pepper
• ¼ tsp salt
• Pinch of ground nutmeg
• 2 tbsp grated Parmesan cheese (optional)

Instructions

Step 1: Prepare the Baking Dish

Preheat the oven to 350°F (175°C). Grease a 9x13-inch (23x33 cm) baking dish with butter or nonstick spray.

Step 2: Layer the Ingredients

Layer half of the croissant pieces evenly in the baking dish. Top with half of the ham, half of the Swiss cheese, and half of the green onions. Repeat with the remaining croissants, ham, cheese, and green onions.

Step 3: Make the Custard

In a large bowl, whisk together the eggs, milk, cream, Dijon mustard, salt, pepper, and nutmeg until well combined.

Step 4: Assemble the Bake

Pour the egg mixture evenly over the layered croissants and ham in the baking dish, pressing down gently to soak.

Step 5: Add Topping

Sprinkle with Parmesan cheese if desired.

Step 6: Bake

Bake uncovered for 30–35 minutes, or until the top is golden and the custard is set in the center.

Step 7: Rest and Serve

Allow to cool for 5–10 minutes before serving.

Zusatztipps für die Zubereitung

Day-old croissants are ideal for this recipe because they absorb the custard better without becoming too soggy. If your croissants are fresh, leave them out uncovered for a few hours or toast them lightly before cutting. When layering, make sure to press down gently after pouring the custard to ensure even soaking throughout. Let the assembled dish sit for 5 minutes before baking to allow the croissants to fully absorb the egg mixture. Use a 9x13-inch baking dish as specified—a smaller dish may overflow, while a larger one could result in a thinner, drier bake.

Varianten und Anpassungen

This recipe is wonderfully adaptable to your taste and what you have on hand. Substitute Gruyère or Emmental for Swiss cheese if you prefer a nuttier, more complex flavor. For extra depth, add a handful of sautéed mushrooms or fresh spinach between the layers. Turkey or chicken can replace the ham for a lighter option, or use crispy bacon for a smokier profile. If you're serving vegetarians, simply omit the meat and add roasted vegetables like bell peppers or zucchini. For a spicier kick, mix a pinch of cayenne pepper into the custard or add sliced jalapeños to the layers.

Serviervorschläge

Serve this Ham & Swiss Croissant Bake with a crisp green salad dressed in a light vinaigrette to balance the richness of the dish. A glass of dry white wine, such as Sauvignon Blanc or Chardonnay, pairs beautifully with the creamy custard and nutty cheese. For brunch, accompany it with fresh fruit and a pitcher of mimosas. Leftovers reheat exceptionally well—simply cover with foil and warm in a 325°F oven for 15–20 minutes, or microwave individual portions for a quick lunch.
