• butter↗1 tablespoon
• brown sugar↗4 tablespoons
• onions, thinly sliced (see note)↗10 cups
• garlic cloves, minced↗4
• vinegar (red wine vinegar)↗2 tablespoons
• salt↗3⁄4 teaspoon
• black pepper, freshly ground↗1⁄4 teaspoon

Step-by-step instructions

1. 1

   NOTE: About those onions -- 10 cups is somewhere between 3 and 4 very large onions. The recipe I took this from called for sweet onions. First time I made it, I used Vidalia -- and thought they made it a little bland. Next time I tried spicier brown onions, and thought it had a lot more flavor.

2. 2

   In a LARGE skillet, melt butter. Add brown sugar and stir until it dissolves.

3. 3

   Add onion and garlic to skillet. Stir to coat with butter/sugar mixture. Cover and cook over medium heat for at least 30 minutes; you can cook them much longer and it will only make it sweeter.

4. 4

   Uncover and add vinegar to onion mixture. Cook, uncovered for at least 10 minutes. (I found I cooked it nearly 45 minutes, to try to reduce some of the liquid.).

5. 5

   Add salt and pepper.

6. 6

   Serve at room temperature or even chilled.
