How healthy are caramelized onions?
Caramelized onions can be a healthy addition to your diet. The caramelization process increases the antioxidant content, providing anti-inflammatory benefits. Onions are also a good source of fiber to aid digestion and quercetin, which may help reduce disease risk.
What do caramelized onions taste like?
Caramelized onions have a delightfully complex flavor that's equal parts sweet and savory. As the natural sugars caramelize, the onions develop a rich, almost candy-like sweetness balanced by an intense umami savoriness.
Do you add salt when caramelizing onions?
Yes, adding salt is recommended when caramelizing onions. The salt helps draw out moisture from the onions, which is necessary for the caramelization process to occur properly. Without salt, it can take much longer for the onions to develop that rich, sweet, caramelized flavor.
Why do you add baking soda to caramelize onions?
Adding a small amount of baking soda to onions helps speed up the caramelization process. The baking soda raises the pH level, making the onions more alkaline and allowing the natural sugars to caramelize and brown more quickly.
Time & Serves
Ingredients
1 batch of Quick Caramelized Onions
3 tablespoons Unsalted Butter
2 cloves Garlic, minced
1 tablespoon Fresh Thyme
4 tablespoons Coconut Cream
1 whole sheet of Puff Pastry, thawed
1 cup Cherry Tomatoes, quartered
1/4 teaspoon Kosher Salt
1/2 teaspoon Black Pepper
Instructions
Prepare the quick caramelized onions and set them aside to cool.
Preheat your oven to 375 °F.
To make the caramelized onion tart, place the butter into a small skillet. Set it over medium-low heat and heat it until the butter melts.
Add the garlic and thyme and cook it for 1–2 minutes until fragrant. Remove the butter mixture from the heat. Set it aside.
Dust your countertop with flour, then place the puff pastry on top of it and unfold it into an even layer. Dust your rolling pin with flour, and roll the whole sheet of puff pastry out slightly.
Cut the puff pastry the whole sheet of puff pastry into 3 even pieces using a sharp knife.
Place each puff pastry rectangle onto a parchment-lined baking sheet in an even layer, then pierce each puff pastry all over with a fork.
Brush each puff pastry with the butter mixture, then top with 1 tablespoon of coconut cream, leaving a 1/2-inch border. Fold each end of the puff pastry over slightly to form a crust and create a pocket for the caramelized onions and tomatoes. Repeat with the remaining puff pastry.
Sprinkle the caramelized onions and tomatoes on top. Sprinkle each caramelized onion tart with salt and black pepper.
Bake the caramelized onion tarts for 15–17 minutes until the puff pastry is golden brown.
Brush the edges of the caramelized onion tarts with the remaining butter mixture, then let them cool for 2–3 minutes before serving.
