Sliced Red Onions

Balsamic Caramelized Onions. The Greatest Thing Since Sliced Bread. No Wait Balsamic Caramelized Onions>Sliced Bread!

That’s math, yo! So let’s get started. First thing’s first. Let me show you how to caramelize onions. This recipe calls for a red onion, so start by cutting the onion through the root and then slice it thinly. You should have half moons like the picture above. Heat a heavy bottomed skillet over medium heat, add a tablespoon of olive oil, and sauté until brown (about 15 minutes).

Now here’s the fun part combine 2 tablespoons of balsamic vinegar and 2 teaspoons of Worcestershire sauce.

What Is Worcestershire Sauce?

Worcestershire sauce is a magical potion distilled from the blood of English wood elves. OK for real, Worcestershire sauce (prounced wist-eh-shur) is actually made from fermented anchovy paste, molasses, vinegar, tamarind, and some other spices. It’s delicious and can add so much flavor to marinades, meat, and in this case, onions.

Take that Worcestershire Sauce and balsamic vinegar combination and add it to the onions along with a big pinch of both kosher salt and freshly ground black pepper. Cook until all the liquid boils off (about 5-10 minutes). When you’re finished the resulting onions should look like the picture below. Remove the onions from the pan and let them cool to room temperature.

A Blue Cheese Dip Made With Greek Yogurt and Sour Cream

That gets all the dairy yums! The next step is to make the actual dip. In a medium bowl, whisk mayonnaise and greek yogurt until well combined. In a separate bowl, gently fold blue cheese crumbles and cream cheese together. It’s important that these two ingredients are at room temperature or else they won’t mix well and the  result will be lumpy. Stir the mayo and greek yogurt mixture into the cheese mixture. Add 4 teaspoons of freshly squeezed lemon juice and mix well. Fold In the balsamic caramelized red onions into the blue cheese dip and season with salt and pepper to taste.

Protip: Make this a day ahead of time. Doing this gives all the flavors of the balsamic caramelized onions time to blend with the creamy dairy.
