Ingredients

• 4 large red onions
• 3 tablespoons unsalted butter
• 1 tablespoon extra virgin olive oil
• 6 sprigs fresh thyme sprigs
• 1 teaspoon honey
• 1 tablespoon balsamic vinegar
• 1 teaspoon kosher salt
• 0.5 teaspoon black pepper

Directions

Step 1

Preheat your oven to 400°F (200°C).

Step 2

Peel the red onions and cut them into halves or quarters, depending on their size. Ensure each piece has a bit of the root intact to hold it together during roasting.

Step 3

In a small saucepan, melt the unsalted butter over low heat. Once melted, stir in the olive oil, honey, and balsamic vinegar until well combined. Remove from heat.

Step 4

Place the red onion pieces in a single layer in a large baking dish or a rimmed baking sheet.

Step 5

Drizzle the butter mixture evenly over the onions. Sprinkle with kosher salt and black pepper to taste.

Step 6

Add the fresh thyme sprigs on top of and around the onions for a fragrant flavor infusion.

Step 7

Roast in the preheated oven for 35-40 minutes, turning the onions halfway through cooking to ensure even caramelization. The onions should be tender and lightly browned on the edges.

Step 8

Remove the onions from the oven and let them rest for a few minutes. Discard the thyme sprigs before serving.

Step 9

Serve warm as a flavorful side dish, or add to salads, sandwiches, or roasted meats.
