Palmiers with Bacon Ingredients

For the Pastry
• Puff Pastry – Use store-bought defrosted puff pastry (like Dufour or Pepperidge Farm) for ultimate flakiness and ease.

For the Filling
• Cream-Style Horseradish – This zesty ingredient adds a unique flavor; adjust to your spice preference!
• Gruyère Cheese – The nutty essence of Gruyère is key; if unavailable, Swiss cheese makes a great substitute.
• Caramelized Onions – Sweet and savory, they deepen the flavor; make these ahead for convenience.
• Bacon – Crispy, crumbled bacon is essential for crunch; turkey bacon can be a lighter alternative.
• Fresh Thyme – This herb enhances the overall flavor beautifully; you can swap it with Italian seasoning if fresh thyme is unavailable.

Optional Toppings

• Black Pepper – A dash of freshly ground black pepper can elevate the flavors and add a touch of heat.

Step‑by‑Step Instructions for Palmiers with Bacon, Gruyère, and Caramelized Onions

Step 1: Prep Puff Pastry
Begin by rolling out one sheet of defrosted puff pastry on a floured surface until it measures roughly 1/8-inch thick. Ensure the pastry is pliable and not sticky. This flaky base is essential for your palmiers with bacon, Gruyère, and caramelized onions, so take your time to achieve an even thickness.

Step 2: Layer Filling
Next, spread 1 tablespoon of cream-style horseradish evenly over the surface of the pastry. Sprinkle 1 cup of Gruyère cheese, followed by 1/3 cup of caramelized onions, half of the crumbled bacon, and 1/2 teaspoon of fresh thyme across the pastry. The filling should be distributed uniformly for balanced flavor in each bite.

Step 3: Roll and Chill
Starting from a long edge, carefully roll the pastry towards the center to form a log, sealing the edges with a little water to prevent spillage. Wrap the log in plastic wrap and refrigerate it for at least 1 hour or freeze for 30 minutes. This step firms up the pastry, making it easier to slice later.

Step 4: Slice
After chilling, unwrap the pastry roll and place it on a cutting board. Using a sharp knife, cut the roll into 1/4-inch thick slices. Make sure your slices are even for uniform baking. These slices will reveal the delightful layers of filling once baked and contribute to the aesthetic of your palmiers.

Step 5: Bake
Preheat your oven to 400°F (200°C) while you arrange the slices on parchment-lined baking sheets, spacing each slice about 1 inch apart. Bake for 12–15 minutes until they puff up and turn golden brown. Rotate the pans halfway through baking to ensure even cooking and a beautifully flaky texture.

Step 6: Serve/Warm Up
Once baked, allow the palmiers to cool on a rack for a few minutes before serving. They are best enjoyed when warm, showcasing their crisp exterior and savory filling. Perfect alongside cocktails or wine, these palmiers with bacon, Gruyère, and caramelized onions are guaranteed to impress your guests!

Make Ahead Options

These Savory Palmiers with Bacon, Gruyère, and Caramelized Onions are perfect for meal prep enthusiasts! You can prepare the filling and assemble the palmiers up to 24 hours in advance; simply layer the ingredients and roll the pastry into a log before wrapping it tightly in plastic wrap and refrigerating. For longer storage, you can even freeze the unbaked slices for up to one month. When you’re ready to serve, bake them straight from frozen without thawing, allowing for a quick and delightful appetizer that’s just as delicious. Just remember, for the best results, ensure they are stored in an airtight container to maintain their flaky texture!

How to Store and Freeze Palmiers with Bacon, Gruyère, and Caramelized Onions

Room Temperature: Store unbaked palmiers for up to 1 day covered with plastic wrap at room temperature to keep the pastry fresh.

Fridge: Baked palmiers can be stored in an airtight container in the fridge for up to 3 days, but note that they are best enjoyed fresh.

Freezer: Freeze unbaked palmiers for up to 1 month. After slicing, lay them out on a baking sheet, freeze until firm, then transfer to a freezer-safe bag.

Reheating: Bake from frozen at 400°F (200°C) for 15–20 minutes until heated through and crispy, ensuring that your palmiers with bacon, Gruyère, and caramelized onions are delightful for serving!

Palmiers with Bacon, Gruyère, and Caramelized Onions Variations

Veggie Boost: Add sautéed spinach or diced sun-dried tomatoes for a healthful twist that complements the savory filling beautifully.
Dairy-Free Delight: Use a dairy-free cheese alternative for a lactose-free version that keeps the rich flavors alive.
Herb Infusion: Try using rosemary or oregano instead of thyme for a fragrant twist that elevates the overall flavor profile.
Spicy Kick: Incorporate crushed red pepper flakes or a dash of hot sauce for an extra layer of heat that will wake up your taste buds.
Creamy Addition: Mix in a small amount of cream cheese with the horseradish for a luscious filling that makes every bite delightfully creamy.
Smoky Flavor: Instead of regular bacon, use smoked bacon or lardons to impart a deeper, more complex taste to your palmiers.

Expert Tips for Palmiers

Chill the Dough: Ensure the puff pastry is sufficiently chilled before cutting. This helps maintain the flaky texture when baking.
Layering Technique: Distributing the filling evenly is crucial. Uneven layers may result in some bites being dry or overly rich; balance is key for the perfect palmiers.
Space Them Out: Don’t overcrowd your baking sheet! Space each palmier about 1 inch apart to allow for optimal puffing and even baking.
Frozen Convenience: For make-ahead ease, freeze unbaked palmiers on a baking sheet, then transfer them to a freezer-safe bag. Bake from frozen without thawing for a quick appetizer.
Watch the Time: Keep an eye on them while they bake. Oven temperatures can vary, so stop baking when they turn golden and flaky to avoid overcooking your palmiers with bacon, Gruyère, and caramelized onions.

Palmiers with Bacon, Gruyère, and Caramelized Onions Recipe FAQs

How do I choose the right puff pastry?
I recommend using store-bought, defrosted puff pastry such as Dufour or Pepperidge Farm. Look for a high-quality pastry that is pliable and free of tears. Avoid any with dark spots or an off smell; freshness is key for the best results!

How long can I store baked palmiers?
Baked palmiers can be stored in an airtight container in the fridge for up to 3 days. However, for the best flavor and texture, I encourage you to enjoy them fresh; they may lose their crispiness over time.

Can I freeze my palmiers before baking?
Absolutely! You can freeze unbaked palmiers for up to 1 month. After slicing, lay the pieces out on a baking sheet and freeze until firm. Then, transfer them to a freezer-safe bag. You can bake them directly from frozen, adjusting the bake time to 15–20 minutes.

Why are my palmiers not puffing up?
A common issue is that the pastry may be too warm when sliced or overcrowded on the baking sheet. Make sure the dough is well-chilled before cutting, and give each palmier enough space while baking. This helps them puff beautifully and achieve that flaky texture!

Are there any dietary considerations for this recipe?
Yes! If you have dietary restrictions, you can substitute bacon with turkey bacon or omit it entirely for a vegetarian version. Also, ensure that the horseradish sauce used is free from allergens if that’s a concern for your guests. Always check packaging for gluten-free options if needed.

How should I reheat leftover palmiers?
For the best results, reheat your leftover palmiers in an oven preheated to 400°F (200°C) for about 8–10 minutes. This will help restore their crispy exterior while keeping the filling warm and delicious. Avoid microwaving, as it can make them chewy.
