Palmiers with Bacon, Gruyère Ingredients
• Perfect for your next gathering!
For the Puff Pastry
- Puff Pastry – This flaky base holds everything together; use defrosted sheets from a 17-ounce package like Dufour or Pepperidge Farm.
For the Filling
- Cream-Style Horseradish (2 tbsp) – Adds a spicy kick; adjust if you prefer a milder flavor.
- Gruyère Cheese (2 cups, shredded) – Gives a nutty flavor and creamy melt; Swiss cheese makes a good substitute.
- Caramelized Onions (½ cup) – They introduce a sweet, rich element; best if made a day in advance.
- Bacon (8 strips, cooked and crumbled) – Provides a smoky, savory taste; cook until crispy for the best texture.
- Fresh Thyme (1 tsp, chopped) – Adds an aromatic herbal note; dried thyme can be used instead if necessary.
Step‑by‑Step Instructions for Savory Palmiers with Bacon, Gruyère, and Caramelized Onions
Step 1: Prepare Dough
On a lightly floured surface, take your thawed puff pastry and, if necessary, roll it out to a thickness of 1/8 inch. This creates a beautiful base for your Savory Palmiers with Bacon, Gruyère, and Caramelized Onions, allowing ample space for the delicious fillings to shine.
Step 2: Layer Ingredients
Spread 1 tablespoon of cream-style horseradish evenly over the rolled pastry, ensuring it reaches the edges. Next, sprinkle half of the shredded Gruyère cheese across the dough, followed by an even layer of caramelized onions, crumbled bacon, and chopped thyme for a fragrant finish that will enrich every bite.
Step 3: Roll Dough
Starting at one long edge of the pastry, carefully roll the dough towards the center. Repeat the process from the opposite side until both ends meet in the middle, creating a neat log. For any loose ends, secure the pastry with a dab of water to hold everything together tightly.
Step 4: Chill
Wrap the rolled dough tightly in plastic wrap and place it in the refrigerator for 1 hour to firm up, or freeze for 30 minutes if you’re short on time. Perfect chilling is crucial for achieving clean, precise cuts and helping your palmiers puff beautifully in the oven.
Step 5: Slice
Once the log has chilled firmly, remove it from the refrigerator and unwrap it. Using a sharp knife, slice the rolled pastry into 1/4-inch thick rounds. Be gentle to maintain the layers of fillings and prevent any filling from spilling out, ensuring each palmier is perfectly packed with goodness.
Step 6: Bake
Preheat your oven to 400°F (200°C). Line baking sheets with parchment paper, and space the palmiers 1-inch apart on the sheet. Bake in the preheated oven for 12-15 minutes, or until they turn golden and flaky, rotating the trays halfway through for even browning and crispiness.
Step 7: Cool and Serve
After baking, allow the palmiers to cool on the baking sheet for 2-3 minutes before transferring them to a wire rack. This brief cooling period helps firm them up for handling. Serve warm for the best experience, and watch your guests delight in these Savory Palmiers with Bacon, Gruyère, and Caramelized Onions!

Tips for the Best Palmiers
-
Chill Dough Properly: Make sure the dough is well-chilled before slicing. This step ensures clean cuts and helps the palmiers achieve their puffiness during baking.
-
Layer Evenly: Distribute the fillings evenly over the dough, as too much filling can lead to messy spills and uneven baking. Balance is key for the best palmiers!
-
Avoid Overcrowding: Leave space between the palmiers on your baking sheet. Crowding can prevent them from rising properly, compromising the desired flaky texture.
-
Watch the Baking Time: Keep an eye on the palmiers while they bake. They should be golden brown, but oven temperatures may vary, so adjust baking time if necessary.
-
Splendid Spice Control: If using a spicier horseradish, taste as you go to ensure it complements rather than overpowers the flavors of your palmiers with bacon, Gruyère, and caramelized onions.
Palmiers with Bacon: Flavor Twists
Feeling adventurous? Customize these savory palmiers with some delightful variations that will make each batch uniquely yours.
-
Prosciutto: Swap bacon for prosciutto for a more delicate flavor that still brings that delightful saltiness.
-
Cheese Options: Try using cheddar or feta instead of Gruyère to introduce sharper, tangy notes to your palmiers.
-
Veggie Delight: Toss in some sautéed spinach or roasted red peppers for a colorful, vegetarian-friendly option that adds great texture.
-
Herb Infusion: Replace fresh thyme with basil or oregano for an aromatic flourish that brightens up the flavors.
-
Add Heat: For those who like a kick, sprinkle in some crushed red pepper flakes or diced jalapeños to the filling.
-
Savory Sweetness: Mix in some finely chopped sun-dried tomatoes or olives to add a savory depth that pairs beautifully with the other flavors.
-
Upgrade the Spice: Experiment with flavored horseradish or add a dash of smoked paprika for a lively twist that will spark your taste buds.
-
Gluten-Free Twist: If you need a gluten-free option, use a gluten-free pastry dough; it may alter the texture, but the taste will still please your palate.
These variations not only make the palmiers your own but can uplift any gathering into a culinary adventure. Pair with a refreshing drink and a few friends, and you’ll have an unforgettable evening! To complement these bites, consider serving them alongside a chilled sparkling wine for that extra touch of celebration. Enjoy exploring your creativity in the kitchen!

Savory Palmiers with Bacon, Gruyère, and Caramelized Onions Recipe FAQs
How do I know when my ingredients are ripe or fresh?
Absolutely! For the best flavor in your Savory Palmiers, make sure your onions are sweet and fragrant, with no dark spots. The Gruyère cheese should be fresh and creamy, while the bacon must be crispy for a delightful texture. If using thyme, opt for vibrant, fresh leaves for maximum aroma.
How should I store leftovers and for how long?
Very good question! Store any leftover baked palmiers in an airtight container in the refrigerator for up to 3 days. This ensures they retain their crispy texture while keeping the flavors intact. It’s a convenient solution for late-night snacks or quick appetizers!
Can I freeze these palmiers? How?
Absolutely! For freezing, wrap the unbaked palmiers tightly in plastic wrap and place them in a freezer-safe container. They can be frozen for up to 1 month. When you’re ready to bake, simply preheat your oven and bake directly from the freezer, adding a few extra minutes to the baking time for perfect puffiness.
What if my palmiers don’t puff up properly?
If your palmiers don’t puff as expected, it could be due to one of a few reasons. Make sure the dough was adequately chilled before slicing; a well-chilled pastry promotes better rising. Additionally, avoid overcrowding on your baking sheet; allow space for each palmier to expand during baking. If they were overfilled, this could also lead to less puff.
Are these palmiers suitable for any dietary restrictions?
Yes! If you want to make these palmiers vegetarian, simply omit the bacon and consider adding sautéed mushrooms or spinach for depth of flavor. If you have guests with gluten sensitivities, using gluten-free puff pastry can also work well to accommodate their dietary needs while keeping all the delightful flavors intact.
