Recipe Information
Ingredients
- 4 medium Yellow onions
- 3 tablespoons Olive oil
- 1 teaspoon Kosher salt
- 1 teaspoon Granulated sugar (optional)
- 2 teaspoons Balsamic vinegar (optional)
Instructions
1. Preheat your indoor grill to medium-low heat. A lower temperature helps prevent the onions from burning while allowing them to caramelize evenly.
2. Peel the yellow onions and cut them into 1/4-inch-thick slices to create even rings. Separate the layers for quicker and more uniform caramelization.
3. In a large mixing bowl, toss the onion slices with olive oil, ensuring they are evenly coated. Sprinkle with kosher salt and optional granulated sugar for enhanced sweetness.
4. Lightly oil the grill grates to prevent sticking, either using a grill-safe spray or by rubbing them with a paper towel soaked in olive oil.
5. Place the onion slices or rings onto the preheated grill in a single layer. Close the grill lid and cook for 5-7 minutes on one side, or until light grill marks appear.
6. Using grill tongs, carefully flip the onion slices to the other side. Continue to cook for another 5-7 minutes.
7. Reduce the heat to low and stir the onions occasionally on the grill using tongs. Allow them to cook for an additional 15-20 minutes, occasionally moving them to prevent sticking or burning.
8. (Optional) In the final 5 minutes of cooking, drizzle balsamic vinegar over the onions and stir well to coat. This adds a tangy depth of flavor.
9. Once the onions are deeply golden and tender, remove them from the grill and transfer to a serving plate.
10. Serve warm as a topping for burgers, sandwiches, salads, or enjoy as a delicious side dish.
