Ingredients

To create the perfect Swiss Cheese and Onion Tarts, gather the following ingredients:

For the Pastry:

• 1 and 1/4 cups of all-purpose flour
• 1/2 cup of unsalted butter, chilled and cubed
• 1/4 teaspoon of salt
• 4 tablespoons of ice-cold water

For the Filling:

• 2 tablespoons of olive oil
• 2 large onions, thinly sliced
• 1 teaspoon of sugar
• Salt and pepper to taste
• 1 cup of Swiss cheese, grated
• 3 large eggs
• 1 cup of heavy cream
• 1/4 teaspoon of nutmeg

Instructions

Preparing the Pastry:

1. Mix Dry Ingredients: In a large bowl, combine the all-purpose flour and salt.
2. Cut in Butter: Add the chilled, cubed butter into the flour mixture. Use a pastry cutter or your fingers to blend until the mixture resembles coarse crumbs.
3. Add Water: Gradually add the ice-cold water, one tablespoon at a time, mixing gently until the dough begins to come together.
4. Chill Dough: Form the dough into a disk, wrap it in plastic wrap, and refrigerate for at least 30 minutes.

Preparing the Filling:

5. Caramelize Onions: In a skillet, heat the olive oil over medium heat. Add the sliced onions and sprinkle with sugar. Cook, stirring occasionally, until the onions turn golden brown and caramelized, about 20-25 minutes. Season with salt and pepper to taste.
6. Preheat Oven: While the onions are caramelizing, preheat your oven to 375°F (190°C).
7. Grate Cheese: Grate the Swiss cheese and set aside.
8. Whisk Eggs and Cream: In a separate bowl, whisk together the eggs, heavy cream, and nutmeg until well combined.

Assembling the Tarts:

9. Roll Out Dough: On a floured surface, roll out the chilled pastry dough to fit into your tart pans. Gently press the dough into the pans and trim any excess.
10. Blind Bake: Line the pastry with parchment paper and fill with baking weights or beans. Bake in the preheated oven for about 10 minutes. Remove the weights and parchment and bake for another 5 minutes until lightly golden.
11. Fill Tarts: Distribute the caramelized onions evenly over the partially baked crusts. Sprinkle the grated Swiss cheese over the onions.
12. Add Egg Mixture: Pour the egg and cream mixture over the cheese and onions, filling each tart nearly to the top.
13. Bake Tarts: Return the tarts to the oven and bake for 25-30 minutes, or until the filling is set and the tops are golden brown.
14. Cool and Serve: Allow the tarts to cool slightly before serving.

Additional Tips

To ensure your Swiss Cheese and Onion Tarts turn out perfectly, consider these additional tips that will enhance the flavor, texture, and overall quality of your dish:

Dough Handling

Keep It Cold: One of the most critical factors in achieving a flaky crust is temperature control. The fats in the dough, whether butter or shortening, need to remain cold as you work with them. Warm fat can melt into the flour, resulting in a dense and tough crust. To keep your dough cold, work in a cool environment, and handle it as little as possible. If you notice that the dough is becoming too soft or sticky while rolling it out, pause your work and place it in the refrigerator for about 10-15 minutes to firm it up again.

Proper Rolling Technique: When rolling out your dough, use a light dusting of flour on your work surface and rolling pin to prevent sticking. Start from the center and roll outward, turning the dough a quarter turn every few rolls to maintain a circular shape. This technique helps achieve an even thickness, which is crucial for even baking.

Chill Before Baking: After you’ve shaped your tart shell and placed it in the pan, chilling it again for about 30 minutes before baking can help prevent shrinking and maintain its shape during the cooking process. This step also allows the gluten in the flour to relax, leading to a more tender crust.

Cheese Variations

Explore Different Cheeses: While Swiss cheese is a classic choice for these tarts, don’t hesitate to get creative with your cheese selections. Gruyère, known for its nutty and slightly sweet flavor, can add depth and complexity to your tart. Emmental cheese, with its mild and creamy profile, is another excellent option that melts beautifully. You might even consider mixing cheeses; a blend of Gruyère and Swiss can create a unique flavor profile that enhances the dish.

Incorporate Other Cheeses: For those who want to venture beyond the Swiss family, consider adding cheeses like Fontina for its creamy texture or a sharp cheddar for a bit of tang. Just keep in mind the melting properties of the cheese you choose, as some cheeses can become oily or grainy when baked.

Onion Caramelization

Patience is Key: Caramelizing onions is an art form that requires patience and attention. Start by slicing your onions thinly to ensure even cooking. Use a heavy-bottomed skillet to provide consistent heat distribution. Begin cooking the onions over medium-low heat, adding a pinch of salt to help draw out moisture. Stir the onions every few minutes, scraping any browned bits off the bottom of the pan to develop flavor without burning.

Timing Matters: The caramelization process can take anywhere from 20 to 40 minutes. As the onions cook, they will gradually turn golden brown and develop a sweet, rich flavor. Avoid the temptation to increase the heat to speed up the process; this can lead to uneven cooking and burnt bits, which detract from the overall taste of your tart.

Deglazing for Extra Flavor: Once your onions are perfectly caramelized, consider deglazing the pan with a splash of white wine, balsamic vinegar, or even a little broth. This will lift the flavorful fond from the bottom of the skillet and infuse your onions with additional depth. Allow the liquid to reduce slightly before adding the mixture to your tart.

Herbs and Spices

Elevate with Aromatics: While the classic Swiss Cheese and Onion Tart is delicious on its own, the addition of herbs and spices can elevate the flavor profile significantly. Fresh or dried thyme pairs beautifully with the sweetness of the caramelized onions and the nuttiness of Swiss cheese. A couple of teaspoons added to the egg mixture can create an aromatic background that enhances every bite.

Experiment with Other Herbs: Rosemary is another excellent choice, offering a robust flavor that complements the richness of the cheese. You might also consider adding a pinch of nutmeg or black pepper to the egg mixture for a subtle warmth and depth. Fresh chives or parsley sprinkled on top just before serving can provide a fresh, bright finish.

Consider Flavor Pairing: When choosing herbs and spices, think about the overall flavor profile you want to achieve. For example, if you’re using Gruyère, you might want to add a touch of garlic powder or onion powder for an extra punch. If using Emmental, consider a hint of mustard powder to enhance its creamy texture.

By incorporating these additional tips into your Swiss Cheese and Onion Tarts preparation, you can ensure a delightful culinary experience that impresses everyone at your table. Happy baking!
