Common Mistakes to Avoid

When making a Caramelized Onion Butternut Squash Tart, it’s easy to overlook some details. Here are common mistakes to avoid to ensure your dish turns out perfectly.

• Skipping the caramelization: Properly caramelizing the onions enhances their sweetness. Take your time with the process; aim for a deep golden color and rich flavor.

• Not seasoning adequately: Under-seasoned filling can lead to blandness. Always taste your mixture before assembling the tart and adjust with salt and pepper as needed.

• Using cold puff pastry: Cold pastry can result in a soggy tart. Make sure to let your puff pastry reach room temperature before rolling it out.

• Overloading on cheese: While cheese adds creaminess, too much can overpower other flavors. Stick to the recommended amount for balance in taste.

• Ignoring cooking times: Each oven is different. Keep an eye on your tart towards the end of baking to prevent burning or uneven cooking.
