At Sweet C’s, I add lots of tips in all of my recipes – because I am a home cook without any formal training, and I find I am more confident making dishes when I understand why it works, and what each ingredient means to the flavor of a recipe – my goal is for even the most beginner home cook to feel empowered in the kitchen.

I want each reader to walk away with a solid knowledge of each recipe, with all of the tips I’ve gathered from extensive testing of each recipe. I also answer questions my friends and family have asked about my recipes, to help everyone better understand the processes we use – and why!

Crowd Pleasing Baked Ham and Swiss Croissant

When I need a quick breakfast, or an easy meal for a hungry group – these baked sandwiches are my go-to! With tons of gooey, melty swiss, buttery croissants, and delicious ham – these croissants take just a few minutes to prep and bake, and you can even make a huge batch and freeze them for grab and go breakfasts!

My kids can be really picky and sometimes lunch is a huge ordeal when everyone wants something different, but these croissant sandwiches are always a crowd pleaser! You can buy croissants at most grocery stores; I like getting the fresh baked ones at Lidl for these sandwiches.

Ingredients For a Ham Cheese Croissant

First assemble the following ingredients:

• Unsalted butter (1/3 cup) – Unsalted butter adds a rich, creamy texture that enhances the flakiness of the croissants.
• Dijon mustard (2 tablespoons) – Dijon mustard introduces a tangy, sharp flavor that complements the savory ham and cheese.
• Green onions (2) – Green onions offer a mild, slightly sweet crunch that adds freshness and a pop of color.
• Honey (1 tablespoon) – Honey brings a touch of sweetness that balances the savory elements of the croissants.
• Sea salt (1/2 tsp) – Sea salt enhances the overall flavor profile, making each ingredient stand out more distinctly.
• Black pepper (1/4 tsp) – Black pepper adds a subtle heat and earthiness, elevating the taste of the ham and cheese.
• Mini croissants (12) – Mini croissants provide the perfect buttery, flaky base that holds all the delicious fillings.
• Ham (1 pound) – Ham contributes a savory, slightly salty flavor that pairs wonderfully with the creamy cheese.
• Swiss cheese (12) – Swiss cheese melts beautifully, adding a smooth, nutty taste that binds the filling together.
• Egg white (1) – Egg white brushed on top gives the croissants a glossy finish and helps the poppy seeds adhere.
• Poppy seeds (2 teaspoons) – Poppy seeds sprinkle on a slight crunch and a decorative touch, making the croissants visually appealing.

How to Make Ham and Cheese Croissants

Once you’ve gathered your ingredients, we will use this method:

1. Prep. Preheat oven to 375 degrees F. Lightly oil a 9 x 13 baking dish or coat with nonstick spray.
2. Combine Spread. In a small bowl, combine butter, Dijon, green onions and honey; season with salt and pepper, to taste.
3. Assemble. Spread butter mixture on each side of the croissants; fill with ham and cheese to make 12 sandwiches. Place croissants in a single layer onto the prepared baking dish.
4. Combine Topping. In a small bowl, whisk together egg white and 1 tablespoon water. Brush tops of croissants with egg white mixture; sprinkle with poppy seeds.
5. Bake. Place into oven and bake until golden brown and toasted, about 15-18 minutes. Let stand 5 minutes. Serve warm.

Ham and Cheese Croissant Tips

Choose high-quality croissants: Opt for buttery, flaky croissants from a reputable bakery or make your own for the best base.

Select the right cheese: Swiss cheese is ideal for its melting qualities and distinctive flavor, but feel free to experiment with variations like Emmental or Gruyère for different tastes.

Use good quality ham: Opt for thinly sliced, high-quality ham for the best flavor and texture. Consider using smoked or honey-glazed ham for an extra flavor boost.

Slice carefully: Gently slice the croissants in half without cutting all the way through to create a pocket for your fillings.

Layer effectively: Start with a layer of cheese on the bottom half of the croissant to prevent the bread from becoming too soggy from the ham.

Wrap in foil: For a softer, more steamed texture, wrap the filled croissants in aluminum foil before baking. For a crispier exterior, leave them unwrapped.

Preheat your oven: Ensure your oven is fully preheated to the recommended temperature (usually around 350°F or 175°C) for even cooking.

Monitor baking time: Bake until the cheese is thoroughly melted and the croissants are just turning golden brown, typically around 10-15 minutes.

Add a finishing touch: For an extra flavor and visual appeal, sprinkle a little grated cheese on top of the croissants during the last few minutes of baking.

Serve warm: These croissants are best enjoyed warm, when the cheese is gooey and the ham is tender.

Pair wisely: Complement your baked Swiss cheese and ham croissants with a light salad or some fresh fruit for a balanced meal.

Experiment with variations: Feel free to add additional ingredients like sliced tomatoes, cooked mushrooms, or caramelized onions for added flavor and texture.

What to Serve with Baked Ham and Cheese Croissants

Fresh fruit salad: A mix of berries, melon, and citrus fruits can provide a refreshing contrast to the rich flavors of the croissants.

Caesar salad: Crisp romaine lettuce, Parmesan cheese, and crunchy croutons dressed in Caesar dressing can complement the savory croissants.

Tomato soup: A creamy or classic tomato soup can serve as a comforting and harmonious pairing with the cheesy, ham-filled pastry.

Coleslaw: A crisp coleslaw with a light vinaigrette can add a crunchy texture and a tangy flavor to balance the meal.
