Common Mistakes to Avoid

Making the perfect Caramelized Onion Butternut Squash Tart can be easy, but there are some common mistakes you should watch out for.

• Overcooking the Onions: If you cook the onions too fast or at too high a temperature, they may burn instead of caramelizing. Cook them slowly on medium heat for a rich flavor.
• Skipping the Seasoning: Failing to season your squash and onions can lead to bland flavors. Always use salt, pepper, and herbs to enhance their natural taste.
• Not Preheating the Oven: Baking in an unheated oven can yield uneven results. Always preheat your oven to ensure even cooking and browning.
• Using Cold Puff Pastry: Cold pastry can shrink during baking. Allow it to come to room temperature for easier rolling and better texture.
• Crowding the Baking Sheet: Overcrowding can steam the squash instead of roasting it properly. Spread the pieces out in a single layer for optimal roasting.
