Ingredients

• 4 large onions, thinly sliced
• ¼ cup balsamic vinegar
• ¼ cup unsalted butter, melted
• 1 tablespoon brown sugar
• Salt and pepper, to taste

Instructions

1. Prepare the Onions:
   Slice the onions thinly and place them in the crockpot. The thinner you slice the onions, the more evenly they will cook and caramelize.
2. Make the Glaze:
   In a small bowl, whisk together the balsamic vinegar, melted butter, brown sugar, salt, and pepper. The brown sugar will help balance the tanginess of the balsamic vinegar, while the butter will give the onions a rich, silky texture.
3. Combine:
   Pour the balsamic mixture over the onions in the crockpot. Stir well to coat all the onions evenly with the glaze. This helps ensure that each onion gets the full flavor of the balsamic glaze.
4. Cook:
   Cover the crockpot and cook on low for 6–8 hours. Stir occasionally to ensure the onions are cooking evenly and developing that deep, caramelized flavor. The onions are done when they are soft, golden brown, and tender.
5. Serve:
   Once the onions are done cooking, serve them warm as a side dish, or use them as a topping for meats, vegetables, or sandwiches. The rich, tangy-sweet flavor will make everything taste even better!
