Description
Experience the robust, earthy sweetness of roasted Tennessee Onions! Thick, half-inch rounds are tossed simply with olive oil and baked at 400°F until tender perfection.
Ingredients
Scale
- 4 large Tennessee Onions, peeled and sliced into 1/2-inch thick rounds
- 3 tablespoons extra virgin olive oil
- 2 tablespoons unsalted butter
- 1 teaspoon kosher salt
- 1/2 teaspoon freshly ground black pepper
- 1 tablespoon high-quality balsamic vinegar
- 2 sprigs fresh thyme
Instructions
- Step 1: Preheat the oven to 400°F (200°C). Peel the Tennessee Onions and slice them into thick, half-inch rounds. Separate the rings slightly and place them in a large mixing bowl.
- Step 2: Drizzle the sliced onions with olive oil, kosher salt, and black pepper. Toss gently to ensure all the onion pieces are evenly coated, then spread them in a single, even layer on a large, parchment-lined baking sheet.
- Step 3: Roast the onions for 20 minutes. Remove the sheet from the oven and carefully turn the onions with a spatula. Return to the oven and roast for an additional 15 minutes, or until the edges begin to soften and turn golden brown.
- Step 4: Reduce the oven temperature to 375°F (190°C). Dot the onions evenly with the unsalted butter and drizzle with the balsamic vinegar. Scatter the fresh thyme sprigs over the surface of the baking sheet.
- Step 5: Return the baking sheet to the oven for 5 to 8 minutes, allowing the butter to melt and the balsamic vinegar to reduce into a sticky, savory glaze that coats the onions.
- Step 6: Remove the baking sheet from the oven. Discard the woody thyme stems and serve the caramelized Tennessee Onions immediately as a side dish.
Notes
- Store any cooled leftovers in an airtight container in the refrigerator for up to four days; they make a fantastic addition to sandwiches or omelets the next day.
- To reheat, spread the onions on a parchment-lined baking sheet and warm them in a 350°F oven for about 10 minutes until sizzling, which helps restore the slightly crisp edges lost in the fridge.
- For a perfect Southern-inspired plate, serve these glazed onions alongside grilled chicken breast or crumble fresh goat cheese over the warm onions just before serving to add a creamy tang.
- Ensure you use a high-quality, thicker balsamic vinegar for the final drizzle, as its rich sweetness is essential for achieving that sticky, restaurant-quality glaze rather than a thin, acidic coating.
