In a large skillet:
1. Heat olive oil and butter over medium-low heat.
2. Add sliced onions along with the sugar.
3. Cook slowly for 20–25 minutes, stirring occasionally until they are deeply golden and caramelized.
4. Once done, remove from heat.
Step 4: Whisk the Egg Mixture
In a mixing bowl:

- Chill pastry before baking: If using homemade pastry, chill it for at least 30 minutes before baking to prevent shrinkage.

Common Mistakes to Avoid
Making Caramelized Onion and Goat Cheese Tartlets can be easy, but there are common pitfalls to watch out for.
- Skipping the caramelization: Not taking your time to caramelize the onions can result in a lack of flavor. Cook them slowly on low heat to bring out their natural sweetness.
- Overbaking the tartlets: Baking them too long can lead to a dry texture. Keep an eye on them and remove them from the oven once they’re set and lightly golden.
- Using cold ingredients: Cold eggs and cream can affect the filling’s consistency. Let your ingredients sit at room temperature for a bit before mixing.
- Ignoring seasoning: Under-seasoned filling can make your tartlets bland. Taste your mixture and adjust salt and pepper as needed before pouring it into the shells.
- Not pre-baking the crusts: Failing to blind bake the tart shells may lead to soggy bottoms. Always pre-bake to ensure they stay crispy.
Refrigerator Storage
- Store in an airtight container for up to 3 days.
- Place parchment paper between layers to prevent sticking.
