Caramelized onions are a great way to add sweetness to lots of dishes. Use this technique for a number of other recipes including French Onion Soup or simply follow this “deconstructed” French onion crostini for a beautiful appetizer.
In a large sauté pan, heat the Avocado Oil over medium heat. Add the onions, Sel Gris, sugar, and Mediterranean Rub.
Cook over medium-low heat, stirring occasionally, as the onions slowly caramelize and reduce, about 50-60 minutes.
Turn the heat up to medium-high and add the wine to de-glaze the pan. Stir in the vinegar. Set aside.
Preheat the oven to 400°F.
Cut the baguette into ¼” slices and arrange on a baking sheet. Drizzle with Rosemary Olive Oil and bake until light brown in color, about 10 minutes.
Top each of the baguette slices with mozzarella cheese, caramelized onions, and a pinch of Mediterranean Rub. Return to the oven until the cheese is melted and golden in color, about 10 minutes. Enjoy!
