Caramelized Onion, Rosemary & Mozzarella Crostini
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.
Ingredients
- 2 Tbsp Avocado Oil
- 3 Onions, cut into 1/2 rings or petals
- 1 tsp Sel Gris Sea Salt (or try our Roasted Garlic Sea Salt)
- 1/2 tsp Sugar
- 1 Tbsp Mediterranean Rub
- 1/4 cup Dry White Wine
- 1 Tbsp Chianti Wine Vinegar or Barrel Aged White Balsamic Vinegar
- 1 crusty Italian Baguette
- 3 Tbsp Wild Rosemary Olive Oil
- 1/2 fresh Mozzarella cheese
Directions
- In a large sauté pan, heat the avocado oil over medium heat. Add the onions, sea salt, sugar, and Mediterranean rub.
- Cook over medium-low heat, stirring occasionally, for 50–60 minutes until onions caramelize and reduce.
- Turn heat to medium-high, deglaze with white wine, then stir in vinegar. Set aside.
- Preheat oven to 400°F.
- Cut baguette into ¼” slices, arrange on a baking sheet, drizzle with rosemary olive oil, and bake until lightly browned, about 10 minutes.
- Top each slice with mozzarella, caramelized onions, and a pinch of Mediterranean rub. Return to oven until cheese is melted and golden, about 10 minutes.
