Step 1

Preheat oven to 375 degrees F.

Step 2

Toss onions: Place onions, garlic and thyme on a large, rimmed sheet pan. Sprinkle with brown sugar, drizzle with 5 tablespoons of oil and season generously with salt and pepper. Toss everything together until evenly coated.

Step 3

Cover the pan with foil and roast in the oven for 25 minutes, tossing once halfway through cooking. Remove foil and continue to cook for an additional 25-35 minutes, or until softened and golden in color, removing onions from the oven and tossing the onions 2-3 during cooking. If you prefer a darker color, switch the oven to broil and broil for 5 minutes - watch the onions carefully as they can easily burn!!

Step 4

Remove the pan from the oven and discard thyme sprigs (SEE NOTES). Drizzle onions with Worcestershire sauce and/or Balsamic if using. Toss to combine.

Step 5

Serve: Taste and adjust for seasoning with salt and pepper. Serve and enjoy!
