Required Equipment & Tools

To make this amazing tart, you’ll need:

Essential Equipment
- Oven
- Large Skillet
- Tart Pan (or pie plate)
- Whisk
- Mixing Bowls
- Baking Sheet (optional for catching drips)
Nice-to-Have Tools
- Food Processor (for easier crust preparation)
- Silicone Baking Mat (for rolling out crust without sticking)

Budget Alternatives

If you’re looking to save some money, you can opt for simple utensils you may already have around the house. A standard baking dish can replace a tart pan if necessary.

Foolproof Step-by-Step Instructions

Step 1: Preheat Your Oven (5 Minutes)

Begin by preheating your oven to 375°F (190°C). This ensures it’s hot enough to start baking your tart evenly as soon as it’s in.

Step 2: Prepare Your Ingredients (5 Minutes)

Slice your onions into thin strips to maximize caramelization.

Pro Tip: To avoid tearing while chopping onions, chill them in the fridge for about 30 minutes before cutting!

Step 3: Caramelize the Onions (15-20 Minutes)

In a large skillet, heat the olive oil over medium heat. Add the sliced onions and toss to coat. Let them cook, stirring occasionally, until they are soft and a deep golden color, about 15-20 minutes.

Common Mistake to Avoid: Don’t rush the process; caramelization takes time and can’t be hasty!

Step 4: Prepare the Crust (5 Minutes)

Roll out your pre-made pie crust and press it gently into your tart pan. Use a fork to poke holes into the bottom.

Step 5: Mix the Custard (5 Minutes)

In a bowl, whisk together the eggs, heavy cream, salt, and pepper until combined.

Step 6: Assemble the Tart (10 Minutes)

Spread the caramelized onions evenly over the crust. Next, sprinkle the grated Gruyère cheese over the onions, followed by pouring the egg mixture evenly on top.

Step 7: Bake (30-35 Minutes)

Place the tart in the preheated oven and let it bake until the filling is set and the top is golden, about 30-35 minutes.

Visual Cue: The filling should wobble slightly but not be liquid when you take it out.

Step 8: Cool and Serve (5 Minutes)

Let the tart cool slightly before slicing. Serve warm, garnished with a sprinkle of fresh thyme if desired.

Professional Chef Secrets

Temperature Control: Ensure the onions are cooked slowly on medium heat for deep caramelization.
Layering Flavors: Add some garlic while sautéing the onions for an aromatic depth.
Presentation Tips: For an elegant finish, garnish with a sprig of fresh thyme or a drizzle of balsamic reduction.
Depth of Flavor: You can sprinkle some cheese on the top of the tart in the last 5 minutes of baking for an extra cheesy crust.

Creative Variations & Adaptations

Seasonal Variations: Make a fall version with squash or sweet potatoes complimenting the onion.
Dietary Modifications: Substitute regular milk and eggs with almond milk and flax eggs for a vegan option!
International Twists: Try adding a hint of nutmeg for a different flavor profile reminiscent of quiches from the region.
Leftover Transformations: Use leftover turkey or chicken for a hearty meal post-holiday.
Make-Ahead Versions: Prepare the tart a day ahead and bake fresh before serving.
