Ingredients

• 226 grams Unsalted butter
• 2 large Yellow onions
• 1 tablespoon Olive oil
• 0.5 teaspoon Salt
• 0.5 teaspoon Sugar
• 0.25 teaspoon Black pepper (optional)

Directions

Step 1

Peel the yellow onions and cut them into thin slices or finely dice them, depending on your texture preference.

Step 2

In a large skillet, heat the olive oil over medium heat.

Step 3

Add the sliced onions to the skillet and sprinkle in the salt and sugar. Stir to coat the onions evenly.

Step 4

Reduce the heat to low and let the onions cook slowly, stirring occasionally, for 30-40 minutes. The onions should become soft, golden brown, and deeply caramelized. If they start to stick to the pan, add 1-2 teaspoons of water as needed, scraping up any browned bits from the bottom of the skillet.

Step 5

Once the onions are caramelized, remove the skillet from heat and let them cool for 10 minutes.

Step 6

In a mixing bowl, allow the unsalted butter to come to room temperature and soften.

Step 7

Add the cooled caramelized onions to the butter, along with black pepper if using. Mix thoroughly until the onions are evenly distributed throughout the butter.

Step 8

Taste and adjust seasoning with more salt or pepper as needed.

Step 9

Transfer the onion butter to an airtight container or roll it into a log using parchment paper. Chill in the refrigerator for at least 1 hour before serving to firm it up.

Step 10

Serve spread on bread, stirred into mashed potatoes, or melted over roasted vegetables. Store any leftovers in the refrigerator for up to 1 week or freeze for up to 3 months.
