Creamy Chili Onion Spread

1.Heat the vegetable oil in a large skillet over medium heat.

2.Add the thinly sliced onions to the skillet. Sauté slowly for 20 to 25 minutes, stirring occasionally, until the onions are deeply caramelized, soft, and sweet. Reduce heat if they begin to brown too quickly.

3.Remove the skillet from the heat and allow the caramelized onions to cool completely to room temperature (about 15-20 minutes). This step is crucial to prevent the mayonnaise from breaking.

4.In a medium bowl, combine the cooled caramelized onions, mayonnaise, chili powder, salt, and black pepper.

5.Mix thoroughly until all ingredients are evenly incorporated and the spread is uniform in color and texture.

6.Taste the spread and adjust seasoning if necessary, adding more salt, pepper, or chili powder to achieve the desired flavor profile.

7.Transfer the creamy chili onion spread to an airtight container and refrigerate for at least 30 minutes before serving to allow the flavors to meld.
