Ingredients and Preparation

Here’s what you’ll need for the sandwich and sauce, along with tips and substitutions for each component:

For the Sandwich:

• 2 large buttery croissants (store-bought or bakery-fresh)
• 2 large eggs
• 1 tablespoon milk or cream (to make the eggs fluffier)
• Salt and pepper to taste
• 1 tablespoon butter or oil (for scrambling eggs)
• 1/2 cup cooked chicken breast, shredded or sliced (grilled or roasted preferred)
• 2 slices of cheddar cheese (or Swiss, provolone, or mozzarella)

For the Maple Mustard Sauce:

• 2 tablespoons Dijon mustard
• 1 tablespoon maple syrup (pure maple syrup for best flavor)
• 1/2 tablespoon mayonnaise (optional, for creaminess)
• 1/2 teaspoon garlic powder (optional, for extra depth)

Preparation Notes:

• Use rotisserie chicken or leftover grilled chicken to save time.
• The croissants should be fresh but firm enough to slice without falling apart.
• Maple syrup should be real, not pancake syrup, to avoid an overly sweet flavor.

Step-by-Step Instructions

1. Prepare the Maple Mustard Sauce.
In a small bowl, whisk together Dijon mustard, maple syrup, and mayonnaise (if using). Add garlic powder if you want a slightly savory kick. Mix until smooth and set aside. This sauce will be spread on the inside of the croissant and gives the sandwich its signature flavor.

2. Cook the Scrambled Eggs.
Crack the eggs into a bowl and beat with the milk or cream, adding a pinch of salt and pepper. Heat a small nonstick skillet over medium heat, melt the butter or oil, then pour in the eggs. Stir gently with a spatula until the eggs are softly scrambled and still slightly moist. Remove from heat—they will continue to cook slightly in the sandwich.

3. Warm the Chicken.
If using leftover or cold chicken, warm it in a skillet or microwave until heated through. Season lightly with salt and pepper if needed. You can also add a little of the maple mustard sauce here for extra flavor.

4. Assemble the Sandwich.
Slice the croissants in half horizontally. Spread a layer of maple mustard sauce on the inside of each half. On the bottom half, layer scrambled eggs, chicken, and cheese. Top with the other half of the croissant.

5. Toast the Sandwich.
Place the assembled sandwich in a skillet or panini press over medium-low heat. Press gently and cook until the croissant is golden and crisp and the cheese has melted—about 3–5 minutes. You can also wrap the sandwich in foil and bake in a 350°F (175°C) oven for 10 minutes if you prefer hands-free cooking.

6. Serve Warm.
Once toasted, slice in half and serve warm. Add more maple mustard sauce on the side if you like a bolder flavor.

Beginner Tips and Notes

• Don’t Overcook the Eggs: Stop cooking when they still look a bit soft. They’ll finish cooking inside the sandwich.
• Avoid Soggy Croissants: Assemble just before toasting. If you prep the sandwich too far in advance, the sauce might make the croissant soggy.
• Cheese Choices: For gooey texture, cheddar is excellent, but mild provolone or mozzarella can make it more kid-friendly.
• Make It Spicy: Add a pinch of cayenne or a slice of jalapeño to give the sandwich some heat.
• Meal Prep Option: Cook and assemble the components ahead of time, then toast when ready to eat. You can also make several at once and reheat them throughout the week.

Serving Suggestions

This sandwich is incredibly versatile and works well in multiple meal settings. Here are a few serving ideas:

• Weekday Breakfast: Pair it with a cup of coffee or a smoothie for a filling, energizing start to your day.
• Weekend Brunch: Serve alongside a fresh fruit salad or a light arugula salad with lemon vinaigrette.
• Lunchbox Upgrade: Wrap in foil and keep in an insulated lunch bag—it will still taste great a few hours later.
• Family Breakfast Platter: Make a batch of these and serve on a breakfast board with berries, yogurt cups, and juice for a cozy brunch spread.

For extra crunch and contrast, you can add baby spinach or arugula to the sandwich just before serving. A tomato slice or a thin layer of sautéed onions can also add a pop of freshness and color.
