| Shredded Swiss, Gruyère, or mozzarella cheese | 1½ cups |
| Cream cheese, softened | ½ cup |

| Black pepper | To taste |
| Fresh parsley or chives, chopped | For garnish |
For the Garlic Butter Topping
| Ingredient | Quantity |
| Unsalted butter, melted | ¼ cup (60 g) |
| Garlic powder | 1 teaspoon |
| Worcestershire sauce | 1 teaspoon |
| Poppy seeds or sesame seeds (optional) | 1 tablespoon |
| Salt | A small pinch |

Step-by-Step Instructions
Step 1: Prepare the Oven and Baking Dish
Preheat your oven to 350°F (175°C).
Lightly grease a 9 × 13-inch baking dish with butter or cooking spray. If your croissants are larger than mini croissants, use a dish that fits them snugly in a single layer.
Set the baking dish aside while you prepare the filling.
Step 2: Make the Creamy Chicken Filling
In a large mixing bowl, combine the shredded chicken, chopped beef ham, softened cream cheese, and Dijon mustard.
Mix thoroughly until the ingredients are evenly coated and the filling becomes creamy. Stir in approximately half of the shredded cheese, reserving the remainder for the topping.
Season with a little salt and freshly ground black pepper. Taste the mixture before adding more salt, since the beef ham and cheese may already be salty.
If the filling seems too thick, add a small spoonful of mayonnaise or a little extra softened cream cheese.
Step 3: Stuff the Croissants
Using a serrated knife, carefully slice each croissant horizontally, leaving one edge attached if you prefer a sandwich-style opening.
Spoon a generous amount of the chicken filling into each croissant, spreading it evenly without overfilling. Gently press the top halves back into place.
Arrange the stuffed croissants in the prepared baking dish in a single layer, leaving a little space between them if possible.
Step 4: Prepare the Garlic Butter Topping
In a small bowl, whisk together the melted butter, garlic powder, Worcestershire sauce, salt, and black pepper.
Using a pastry brush or spoon, distribute the garlic butter evenly over the tops of the stuffed croissants.
Sprinkle the remaining shredded cheese over the croissants. If desired, finish with poppy seeds or sesame seeds for extra texture and a bakery-style appearance.
Step 5: Bake Until Golden and Cheesy
Cover the baking dish loosely with aluminum foil and bake for 10 minutes. This helps heat the filling without browning the pastry too quickly.
Remove the foil and continue baking for another 8–10 minutes, or until the croissants are golden brown, the cheese is melted and bubbly, and the filling is thoroughly heated.
If you prefer a deeper golden color, leave the dish uncovered for the final few minutes, watching carefully to prevent the croissants from burning.
Remove the dish from the oven and let the croissants rest for 2–3 minutes.
Step 6: Garnish and Serve
Sprinkle the baked croissants with freshly chopped parsley or chives.
Serve warm while the pastry is flaky, the cheese is melted, and the creamy chicken filling is deliciously tender.
These stuffed croissants are best enjoyed fresh from the oven, alongside a crisp salad, fresh fruit, or a bowl of warm soup.
Best Tips
Use croissants that are fresh but sturdy enough to hold the filling without falling apart. Let the cream cheese soften before mixing to create a smooth filling, and avoid adding too much filling because it can spill out during baking. Shred your own cheese for a smoother melt, and brush the garlic butter evenly across the tops. If your croissants are already very dark or delicate, reduce the uncovered baking time and keep a close eye on them.
Best Ingredient Options
Rotisserie chicken is a convenient choice because it is already cooked and easy to shred. Swiss cheese and Gruyère provide a rich, savory flavor, while mozzarella creates a softer, stretchier topping. Beef ham adds a salty, meaty flavor, but cooked shredded beef can also be used. Cream cheese creates a thick, creamy filling, while mayonnaise offers a lighter, tangier alternative. Dijon mustard provides a balanced sharpness, and honey mustard adds a slightly sweeter flavor.
Recipe Variations
For a spinach and cheese version, mix a handful of well-drained cooked spinach into the chicken filling. If you enjoy a stronger flavor, add a little smoked paprika, dried Italian herbs, or finely chopped green onions. You can also replace the beef ham with extra chicken or cooked, seasoned ground beef. For a breakfast-inspired variation, add scrambled eggs to the filling and serve the croissants with fresh fruit. If you prefer a lighter version, use reduced-fat cream cheese and a smaller amount of cheese on top.
What to Serve With Stuffed Croissants
These cheesy chicken croissants pair wonderfully with a fresh green salad, cucumber and tomato salad, roasted vegetables, or steamed broccoli. For breakfast or brunch, serve them with fresh berries, sliced melon, or a simple fruit salad. A bowl of tomato soup or creamy vegetable soup makes them an excellent lunch or light dinner.
For a complete meal, combine one or two stuffed croissants with a vegetable side and a refreshing drink.
Make-Ahead Instructions
Prepare the chicken filling up to 24 hours in advance and store it in an airtight container in the refrigerator.
For the best texture, stuff the croissants shortly before baking. You can also assemble the croissants in the baking dish a few hours ahead, cover them, and refrigerate until ready to cook.
Brush with the garlic butter and add the final cheese topping just before baking. If baking directly from the refrigerator, allow a few extra minutes for the filling to heat through.
Storage Instructions
Allow leftover croissants to cool slightly, then transfer them to an airtight container and refrigerate within 2 hours of cooking.
Store in the refrigerator for up to 3–4 days. The pastry may soften as it absorbs moisture from the filling, but reheating in the oven or air fryer can help restore some of its crispness.
Reheating Instructions
Oven: Preheat to 325°F (165°C). Place the croissants in an oven-safe dish and cover loosely with foil. Heat for approximately 10–15 minutes, removing the foil during the final few minutes to crisp the pastry.
Air fryer: Reheat at 320°F (160°C) for approximately 4–7 minutes, checking frequently to avoid over-browning.
Microwave: Heat an individual croissant for 30–60 seconds, then check that the filling is hot. The microwave is convenient, but the pastry will be softer rather than flaky.
Ensure the filling reaches 165°F (74°C) when reheating leftovers.
Freezing Instructions
For the best results, freeze the assembled stuffed croissants before baking. Wrap each one individually and place them in a freezer-safe container for up to 2 months.
Thaw overnight in the refrigerator before adding the garlic butter and baking. Alternatively, freeze fully baked croissants after cooling, then reheat them in the oven until hot throughout.
Keep in mind that croissants may lose some of their original flaky texture after freezing and thawing.
Common Mistakes to Avoid
Overfilling the croissants can cause the filling to spill out and make the pastry soggy. Using cream cheese straight from the refrigerator may create a lumpy filling, so soften it before mixing. Baking at too high a temperature can brown the outside before the center is hot, while covering the dish for too long can prevent the croissants from becoming crisp. Finally, avoid adding excessive salt before tasting the filling, as the cheese and beef ham already contribute saltiness.

Frequently Asked Questions
Can I use regular croissants instead of mini croissants?
Yes. Standard croissants work very well. Slice them horizontally and fill them with the chicken mixture. You may need a larger baking dish and a little extra filling depending on their size.
Can I use leftover roasted chicken?
Absolutely. Leftover roasted chicken or rotisserie chicken is ideal for this recipe. Remove any bones and skin, then shred or dice the meat before mixing it with the other ingredients.
What cheese melts best in stuffed croissants?
Swiss, Gruyère, and mozzarella are excellent options. Cheddar also works well if you prefer a stronger cheese flavor. A combination of mozzarella and cheddar gives you both stretchiness and a savory finish.
Can I make these croissants without cream cheese?
Yes. Substitute mayonnaise or a thick plain cream cheese alternative. You can also use a mixture of mayonnaise and a little plain Greek yogurt, although the filling will have a slightly different texture and flavor.
How do I prevent the croissants from becoming soggy?
Avoid adding excessive filling or watery ingredients. Use cooked chicken that is not overly wet, and bake uncovered long enough to crisp the pastry. For the best result, serve the croissants shortly after baking.
Can I make this recipe ahead for a party?
Yes. Prepare the filling in advance and assemble the croissants shortly before guests arrive. Bake them just before serving so the pastry stays flaky and the cheese remains melted.
Can I make these stuffed croissants gluten-free?
You can use suitable gluten-free croissants and check that the Worcestershire sauce, mustard, and other packaged ingredients meet your dietary requirements. The texture may differ from traditional croissants.
Can I serve these croissants for breakfast?
Definitely. They make a delicious savory breakfast or brunch, especially when served with fresh fruit, scrambled eggs, or a simple green salad.
