How to Store and Freeze Onion and Goat Cheese Tarts
Fridge: Store leftover tarts in an airtight container in the fridge for up to 2 days. To enjoy them warm, simply reheat in the oven to maintain crispness.
Freezer: If you have extra tarts, freeze them before baking. Wrap each tart tightly in plastic wrap and foil, and they’ll last for up to 2 months.
Reheating: Bake frozen unbaked tarts directly from the freezer at 400°F (200°C) for 20-25 minutes or until golden brown. For baked tarts, reheat at a lower temperature to avoid over-browning.
Cooling: Allow tarts to cool completely before refrigerating or freezing to maintain their delightful texture.

Onion and Goat Cheese Tarts Recipe FAQs
What type of onions should I use for the tarts?
Absolutely! Sweet onions like Vidalia or Yellow onions work best for caramelizing, bringing out a natural sweetness. Avoid using red onions as they may not achieve the same rich flavor in this dish.
How long can I store the leftover tarts?
You can store leftover tarts in an airtight container in the fridge for up to 2 days. To enjoy them warm, I recommend reheating them in the oven for about 10-15 minutes at 350°F (175°C) to retain their crisp texture.
Can I freeze unbaked Onion and Goat Cheese Tarts?
Yes! To freeze unbaked tarts, wrap each one tightly in plastic wrap and then in foil. They will stay fresh for up to 2 months. When you’re ready, bake them straight from the freezer at 400°F (200°C) for 20-25 minutes, keeping an eye on them until they’re golden.
What should I do if my onions are not caramelizing properly?
If your onions are browning too quickly and not caramelizing, reduce the heat. Cooking them on medium-low allows for the sugars to develop, turning them soft and jammy. Stir them occasionally to ensure even cooking; this process should take about 20 minutes.
Are there any dietary considerations for pets or allergies?
Goat cheese is generally safe for humans but could be a concern for those with a lactose intolerance or dairy allergies. Also, be mindful that onions are toxic to dogs, so if these tarts are for a gathering that includes pets, it’s best to keep them away from the food!
Can I customize the filling with other ingredients?
The more the merrier! You can certainly add herbs such as rosemary for an extra layer of flavor or even incorporate sautéed mushrooms for some umami goodness. Drizzling honey before baking will also add a delightful sweetness, making the tarts unique to your taste!
