Ingredients

  • 2 large red onions cut into 1/4-1/2 inch thick slices
  • 1 head garlic pointy end cut off
  • 2 tablespoons olive oil
  • 1 teaspoon sugar
  • 1/4 teaspoon salt
  • 1 cup 2% Greek yogurt
  • 1/4 cup sour cream
  • 1.5 teaspoons Worchestershire sauce
  • pepper to taste
  • fresh thyme for serving

Instructions

  • Preheat the oven to 400ºF.
  • Spread the sliced onions onto baking sheet and place the head of garlic cut-side down onto the baking sheet. Drizzle with olive oil, season with sugar and salt, and toss to combine.
  • Bake for 15 minutes.
  • Remove the pan from the oven and use a spatula to make an onion pile (scoot all of the onions together). Flip over the head of garlic.

  • Place back into the oven and bake for another 15 minutes. After 15 minutes, toss again. If the onions have reduced in size and turned a dark golden brown/dark purple color, you know they are done. If the onions are still plump and light in color, they need to continue cooking.
  • Once the onions have caramelized, transfer the onions and head of garlic to a cool baking sheet or plate. Set aside to cool.
  • After the head of garlic is cool enough to handle, use your hands to squeeze out the cloves into a large bowl. Use a fork to mash the roasted garlic into a paste.

  • Use a pair of kitchen scissors to cut the caramelized onions into smaller, bite-sized pieces and transfer into the large bowl.
  • Mix the onions with the rest of the dip and taste test. Add additional salt/pepper if needed.
  • Garnish with fresh thyme and serve with your favorite crackers, pretzels, veggies, breads, bagels, and more!
