• Get ready to indulge in these savory delights!

- Cooked Bacon – Adds a savory crunch; feel free to use turkey bacon for a leaner version.
- Gruyère Cheese – Imparts a creamy, nutty flavor; Swiss cheese is a great substitute if needed.
- Caramelized Onions – Provides a sweet depth; make them ahead for quicker assembly.
- Cream-Style Horseradish – Gives a mild kick and enhances flavor; start with 1 tablespoon per sheet for balanced zest.

Step‑by‑Step Instructions for Bacon, Swiss, and Caramelized Onions
Step 1: Prepare the Puff Pastry
Begin by preheating your oven to 400°F (200°C). Roll out one sheet of defrosted puff pastry on a lightly floured surface until it’s about 1/8-inch thick. This ensures a wonderfully flaky texture in your Bacon, Swiss, and Caramelized Onions palmiers. Use a rolling pin for even thickness, and keep an eye out for any tears in the pastry.
Step 2: Layer the Ingredients
Spread 1 tablespoon of cream-style horseradish evenly across the pastry, leaving a small margin around the edges. Next, sprinkle half of the Gruyère cheese over the horseradish, followed by the caramelized onions, cooked bacon, and fresh thyme. This combination creates a delicious, savory filling that richly flavors the palmiers, making each bite delightful.
Step 3: Roll and Shape
Starting from one long end of the puff pastry, roll it tightly towards the center while maintaining a uniform shape. Then, take the opposite end and roll it inwards until the two rolls meet. If needed, use a little water to seal the ends. This step is crucial to ensuring that your Bacon, Swiss, and Caramelized Onion palmiers hold their shape during baking.
Step 4: Chill & Slice
Wrap the rolled pastry log in plastic wrap and refrigerate it for at least 1 hour or freeze it for 30 minutes. Chilling firms up the dough and makes slicing much easier. Once chilled, unwrap the log and use a sharp knife to slice it into 1/4-inch thick pieces, laying them out flat on a parchment-lined baking sheet.
Step 5: Bake
Place the sliced palmiers in the preheated oven and bake for 12-15 minutes or until they are golden brown and puffed up. Keep an eye on them as they bake, enjoying the aroma of bacon and cheese filling your kitchen. This is when the magic happens, transforming your layered pastry into delectable Bacon, Swiss, and Caramelized Onions treats.
Step 6: Serve
Once the palmiers are golden and flaky, remove them from the oven and allow them to cool slightly on the baking sheet. Serve them warm to capture the fullness of flavors; they make an elegant appetizer for any gathering. Enjoy sharing this lovely creation with your friends and family!

How to Store and Freeze Bacon, Swiss, and Caramelized Onions
Room Temperature: Store any leftover palmiers in a cool, dry place, covered loosely with foil for up to 2 hours to keep them warm without getting soggy.
Fridge: For longer storage, place cooled palmiers in an airtight container and refrigerate for up to 3 days. Reheat in the oven to restore crispiness.
Freezer: Assemble and freeze uncooked palmiers for up to 1 month. Simply bake them from frozen, increasing baking time to 15-18 minutes for perfectly flaky treats.
Reheating: To enjoy leftovers, reheat the palmiers in the oven at 350°F for about 10 minutes, ensuring they regain their delightful crunch.
Make Ahead Options
These Savory Bacon & Gruyère Palmiers are perfect for meal prep enthusiasts looking to save time during busy weeknights! You can prepare the palmiers up to 24 hours in advance by assembling them and then wrapping them tightly in plastic wrap before refrigerating. This keeps the pastry fresh while allowing the flavors to meld beautifully. Alternatively, you can freeze the unbaked palmiers for up to one month; simply slice and lay them on a parchment-lined baking sheet, then freeze until solid before transferring to a freezer bag. When ready to bake, there’s no need to thaw—just pop them straight into the oven for 12-15 minutes while enjoying the irresistible aroma that fills your kitchen. With these tips, you’ll serve up restaurant-quality appetizers without the last-minute rush!

Bacon, Swiss, and Caramelized Onions Recipe FAQs
How do I choose the best puff pastry for my palmiers?
Absolutely! For the best results, I recommend using high-quality puff pastry like Dufour, which is made with butter, resulting in a rich flavor and crisp texture. If you can’t find Dufour, Pepperidge Farm is a good alternative made with vegetable oil, providing a slightly different but still delightful texture.
What’s the best way to store leftover palmiers?
Very good question! If you have any leftovers, place them in an airtight container and refrigerate them for up to 3 days. To keep that delicious crispiness, reheat them in the oven at 350°F for about 10 minutes when you’re ready to enjoy them again. This will help them regain their delightful crunch!
Can I freeze the palmiers before they are baked?
Yes, you can! I often make a batch ahead of time. Simply assemble the palmiers, wrap them tightly in plastic wrap, and freeze for up to 1 month. When you’re ready to bake, there’s no need to thaw—just pop them straight into the preheated oven, adding a few extra minutes to the baking time (15-18 minutes) until they are golden and flaky.
What should I do if my palmiers aren’t puffing up properly?
If you find that your palmiers aren’t puffing up as expected, there are a few things to check. First, ensure that your puff pastry was adequately chilled before baking; this is crucial for achieving that delightful rise. Also, check that you’ve preheated your oven properly and that it is at the correct temperature of 400°F. Lastly, during assembly, try to avoid pressing the layers too firmly—keeping them light and airy allows for maximized puffing!
Can I make a variation of these palmiers, perhaps for dietary considerations?
Absolutely! Feel free to swap out Gruyère for sharp cheddar or Monterey Jack for a different flavor profile. If someone has a dairy allergy, you can explore plant-based cheese options available today. For a delightful twist, consider adding spinach or chopped sun-dried tomatoes to the filling. Remember, the more the merrier in terms of creativity with your filling!
