What are the best onions to use for caramelized onions?

You can make caramelized onions with any onion, like yellow, red, sweet or even shallots. A sweet onion, like Vidalia, will produce sweeter caramelized onions, but even yellow onions will get very sweet when caramelized.

What cheese can I substitute for goat cheese?

The unique creamy texture and grass-like tang of goat cheese is very unique, but if you need to make a substitution you can use cream cheese, feta cheese or even blue cheese.

Caramelized Onion and Goat Cheese Tart

Description

This Caramelized Onion and Goat Cheese Tart is a classic for a reason. The flavor combination of rich and sweet caramelized onions with tangy goat cheese on a flaky and buttery crust works incredibly well.

1 Tbsp. olive oil
1 Tbsp. unsalted butter
2 tsp. fresh thyme, divided
1/2 tsp. table salt

Instructions

Add onions, oil, butter, 1 teaspoon thyme, salt and pepper to a large skillet with a lid (or a Dutch oven or large saucepan with a lid). Turn on heat to medium and place lid on skillet. Cook, undisturbed, for 10 minutes, then stir and reduce heat to medium-low and continue to cook, with the lid on, until the onions are golden grown, stirring every 10 minutes. This will take about 20-30 minutes more. Remove lid and increase heat to medium-high and cook, stirring occasionally, until dark brown and very tender, another 5 minutes. Remove from heat and set aside at room temperature for 5 minutes.
Preheat oven to 425F and line a baking sheet with parchment paper. Roll puff pastry to a 10- by 12-inch rectangle Transfer to prepared baking sheet and dot with a fork, leaving a 1-inch border. Top pastry evenly with onions, leaving a 1-inch border, then top evenly with crumbled goat cheese and remaining 1 teaspoon thyme.
Transfer baking sheet to oven and immediately reduce temperature to 375F. Cook until the pastry is golden brown and the cheese is starting to brown, 25-30 minutes. Remove from the oven and cool at room temperature for 10-15 minutes before slicing. Garnish with more fresh herbs, microgreens or arugula.

Notes

Be sure to keep the puff pastry cold as you work with it. If you need to walk away from it at any point, transfer to the refrigerator.
You can make the caramelized onions up to 3 days ahead of time and store in an airtight container in the refrigerator.
You can even roll out the pastry up to 1 day ahead of time and store loosely covered with plastic wrap in the refrigerator for up to 1 day.
You can also garnish with reduced balsamic vinegar, pomegranate molasses, honey or hot honey.
