Ingredients Method Notes

Ingredients
  

  • Several medium to large onions Yellow, white, or red varieties work well
  • 1 tablespoon unsalted butter optional for richness
  • A drizzle of extra virgin olive oil to help caramelize evenly
  • A dash of cracked black pepper for subtle warmth
  • A pinch of kosher salt to enhance sweetness
  • 1/2 teaspoon light brown sugar optional for balance
  • 1 teaspoon aged balsamic vinegar optional for tang
  • 1/4 teaspoon fresh thyme leaves optional for herbal notes

Method
 

Step 1: Prepare Your Onions
  1. Start by peeling your onions. This is the least exciting part, but it’s crucial. Once peeled, slice the onions. Aim for thin slices to allow for even cooking. The thinner the slice, the faster they’ll caramelize.
Step 2: Heat the Pan
  1. Grab a large skillet and place it over medium-low heat. You want a non-stick skillet for an easy cooking experience. Add a drizzle of olive oil, and then, if using, toss in your butter. Allow it to melt, coating the pan.
Step 3: Add the Onions
  1. Once the oil is hot, carefully add the sliced onions. They should sizzle a little but not burn. Stir them to coat with oil. This is where the magic begins.
Step 4: Season the Onions
  1. Sprinkle the pinch of kosher salt over the onions. This draws out moisture, which helps with the caramelization process. If you’re including brown sugar, thyme, or vinegar, now’s the time to add them in. Mix them well.
Step 5: The Waiting Game
  1. Lower the heat to medium-low and toss the onions every few minutes. The goal is to let them cook slowly. You want them to gradually turn golden brown. This process typically takes about 30 to 40 minutes, but don’t rush it.
Step 6: Stir for Great Results
  1. Check on your onions every 5-10 minutes. If they are sticking to the pan, you can add a tablespoon of water or broth to deglaze. Keep stirring, and when they get to a rich golden color, they’re ready.
Step 7: Taste and Adjust
  1. Before serving, taste the onions. If you’d like more sweetness, adjust with a bit more brown sugar or vinegar.

Notes

  • Go Low and Slow: The key to perfect caramelized onions is patience. Don’t rush the process.
  • Use Quality Ingredients: A good quality olive oil makes a significant difference.
  • Stir Regularly: While it’s essential to let the onions do their magic, stirring ensures they don’t stick or burn.
  • Experiment with Flavors: Don’t hesitate to add a splash of balsamic or a sprinkle of herbs like thyme or rosemary to elevate flavors.
  • Scale Up: Feel free to make a big batch. These keep well in the fridge and can boost multiple meals throughout the week.
