• Get ready to create a mouthwatering delight!
For the Crust
- Puff Pastry – The key to a flaky, buttery base; ensure it’s fully thawed before use.
- Butter – Adds a delicious richness; olive oil can be a lighter alternative.
For the Filling
- Olive Oil – Perfect for sautéing onions; you can use more butter instead if desired.
- Onions (thinly sliced) – The heart of the dish; opt for yellow or white onions for optimal sweetness.
- Sugar – Aids in caramelizing the onions; brown sugar deepens the flavor beautifully.
- Salt – Essential for balancing the flavors of the dish.
- Heavy Cream – Brings creaminess to the filling; substitute with milk for a lighter touch.
- Egg – Binds the ingredients together; consider a flax egg for a vegan version.
- Black Pepper – Adds subtle spice; feel free to season it to your liking.
- Gruyère Cheese (shredded) – Offers a nutty richness; Swiss cheese or sharp cheddar are great alternatives.
- Dijon Mustard (optional) – Introduces a tangy depth beneath the cheese; it can be skipped if you prefer.
For the Garnish

Step‑by‑Step Instructions for Golden Caramelized Onion & Gruyère Puff Pastry Tart is delightful!
Step 1: Sauté the Onions
In a large skillet, melt 2 tablespoons of butter and 1 tablespoon of olive oil over medium heat. Add 3 thinly sliced onions, 1 tablespoon of sugar, and 1 teaspoon of salt. Cook slowly for 25-30 minutes, stirring occasionally, until the onions are golden brown and jammy in texture. This caramelization process deepens their natural sweetness, creating a rich flavor for your tart.
Step 2: Preheat the Oven
While the onions are caramelizing, preheat your oven to 400°F (200°C). This step is crucial for achieving that golden, flaky texture in the puff pastry. Make sure your oven is fully preheated before baking to ensure even cooking throughout the tart, giving it a perfectly puffed appearance when finished.
Step 3: Prepare the Puff Pastry
Lay your thawed puff pastry on a parchment-lined baking sheet. Use a sharp knife to score a 1-inch border around the edges, being careful not to cut all the way through. Gently prick the center of the pastry with a fork to allow steam to escape while baking. This will help you achieve a beautifully risen crust that cradles the delightful filling.
Step 4: Whisk the Filling
In a medium bowl, whisk together 1/2 cup of heavy cream, 1 beaten egg, 1/4 teaspoon of black pepper, and 1 cup of shredded Gruyère cheese. If you’d like, add a pinch of nutmeg for extra flavor. The cream and cheese create a rich, savory filling that pairs perfectly with the sweetness of the caramelized onions in your Golden Caramelized Onion & Gruyère Puff Pastry Tart.
Step 5: Assemble the Tart
If you’re using Dijon mustard, spread a thin layer on the pastry base. Pour the cheese mixture onto the pastry, spreading it evenly. Next, top the filling with the caramelized onions, distributing them evenly for the best flavor in every bite. At this point, the tart is coming together beautifully, ready to transform in the oven.
Step 6: Bake the Tart
Place the assembled tart in the preheated oven and bake for 15-18 minutes. Keep an eye on it as it cooks; the pastry should rise and turn a beautiful golden brown. This short baking time ensures the puff pastry achieves that irresistible flakiness while the filling becomes luscious and creamy.
Step 7: Garnish and Serve
Once baked, remove your Golden Caramelized Onion & Gruyère Puff Pastry Tart from the oven. Allow it to cool for a few minutes, then garnish with fresh thyme and a sprinkle of sea salt. Slice into wedges and serve warm or at room temperature, allowing everyone to enjoy this delightful combination of flavors!
Make Ahead Options
These Golden Caramelized Onion & Gruyère Puff Pastry Tarts are perfect for busy home cooks who appreciate meal prep! You can prepare the filling by cooking the onions and mixing the cream, egg, cheese, and seasonings up to 24 hours in advance; refrigerate them in an airtight container to maintain freshness. Additionally, you can assemble the entire tart (without baking) and keep it covered in the fridge for up to 3 days. When you’re ready to serve, simply bake the tart straight from the fridge for 15-18 minutes at 400°F (200°C), ensuring it puffs beautifully and stays just as delicious as if made fresh!
