Savory Palmiers with Bacon, Gruyère Ingredients
For the Pastry
• Puff Pastry – This flaky base will give your palmiers that delightful texture; I recommend brands like Dufour for a buttery flavor or Pepperidge Farm for a straightforward option.
For the Filling
• Cream-Style Horseradish – Adds a mild, tangy kick that complements the savory elements beautifully; feel free to adjust the quantity for extra spice!

• Bacon – Delivers that savory crunch; ensure it’s crispy and crumbled for the perfect bite!
• Fresh Thyme – Introduces a lovely aromatic herb flavor; dried thyme can work well too if you’re in a pinch.

Step‑by‑Step Instructions for Savory Palmiers with Bacon, Gruyère, and Caramelized Onions
Step 1: Prepare Pastry
Start by laying one sheet of defrosted puff pastry on a lightly floured surface. Use a rolling pin to gently roll the pastry to about 1/8-inch thickness, ensuring it remains even throughout. This will create a perfect base for your Savory Palmiers with Bacon, Gruyère, and Caramelized Onions.
Step 2: Layer Fillings
Spread 1 tablespoon of cream-style horseradish evenly across the rolled-out pastry, enhancing flavor. Next, sprinkle 1 cup of shredded Gruyère cheese over the horseradish, followed by 1/3 cup of caramelized onions. Add half of the crumbled bacon and 1/2 teaspoon of fresh thyme for a perfectly balanced filling.
Step 3: Roll Dough
With the fillings in place, use plastic wrap to compress the layers gently, ensuring they stick together. Then, starting from both long sides, carefully roll the pastry toward the center. If needed, dab the edges with water to keep the log secure. This step will shape the palmiers beautifully.
Step 4: Chill
Wrap the rolled pastry log in plastic wrap and place it in the refrigerator for at least 1 hour to firm up. Alternatively, you can freeze it for about 30 minutes if you’re short on time. Chilling is crucial for achieving clean cuts and maintaining the shape of your Savory Palmiers.
Step 5: Slice
Once chilled, carefully unwrap the dough and use a sharp knife to cut the log into 1/4-inch thick slices. Be sure to maintain even pressure while slicing to preserve the filled layers. Lay the slices flat on a parchment-lined baking tray, ready for baking to golden perfection.
Step 6: Bake
Preheat your oven to 400°F (200°C) while you arrange the sliced palmiers on the baking sheet. Bake the palmiers for 12-15 minutes, watching closely for a golden-brown color and that irresistible flaky texture. Your kitchen will soon be filled with the savory aroma of these delightful treats.
Step 7: Cool and Serve
Allow the Savory Palmiers to cool slightly on the baking sheet before transferring them to a serving platter. They’re best enjoyed warm, so serve them immediately for a delightful appetizer. These palmiers make for a fantastic treat at any gathering, perfect for sharing with friends!

Expert Tips for Savory Palmiers
Chill for Clean Cuts: Ensure your pastry is well-chilled before slicing to prevent squishing the layers—this is key for beautiful, flaky Savory Palmiers with Bacon, Gruyère, and Caramelized Onions.
Adjust Spice Levels: Start with less cream-style horseradish; you can always add more. Taste as you go to achieve the perfect tangy kick!
Use Crispy Bacon: Make sure your bacon is cooked crispy before crumbling; soggy bacon can compromise the texture of your palmiers after baking.
Avoid Overfilling: Don’t pack too many toppings into the pastry. This can lead to overflowing and uneven baking—keep it balanced for the best results!
Bake from Frozen: If prepped in advance, these can be baked directly from frozen. Just add a couple of extra minutes to the baking time for perfect palmiers!

I recommend using Dufour puff pastry for a buttery flavor or Pepperidge Farm for a vegetable oil option. Both will create that delightful flaky texture essential for your Savory Palmiers with Bacon, Gruyère, and Caramelized Onions.
How should I store leftover palmiers?
To maintain freshness, let the palmiers cool completely before placing them in an airtight container at room temperature for up to 2 days. If you’d like to keep them longer, you can wrap them tightly and refrigerate for up to 5 days, then simply reheat in the oven to restore their crispiness.

Soggy bacon can affect the overall texture of the palmiers, so this step is crucial for achieving that delightful crunch in every bite. If you find your bacon isn’t crispy, you can always place it back in the pan for a few extra minutes until it’s perfectly cooked.
Are there any dietary considerations?
If you have dietary restrictions or guests with allergies, feel free to adjust the ingredients. For a vegetarian version, simply swap the bacon for sautéed mushrooms or spinach! Always ensure that your cheese choice accommodates any lactose intolerance, with options like dairy-free cheese available for those who need it.
