Yield 4-6 1x


  • 2 large red onions, sliced
  • 1 head garlic, pointy end sliced off
  • 2 tablespoons olive oil
  • 1 teaspoon sugar (white, coconut, turbinido, etc.)
  • 1/4 teaspoon salt
  • 1 cup 2% Greek yogurt
  • 1/4 cup sour cream
  • 1.5 teaspoons Worchestershire sauce
  • pepper, to taste


  1. Preheat oven to 400ºF.
  2. Then, prep veggies by thinly slicing the onion and cutting the pointy end of the garlic off.
  3. Spread onions onto baking sheet and generously drizzle with olive oil and toss.
  4. Add garlic head and drizzle with olive oil.
  5. Season with sugar and salt and toss the onions again.
  6. Roast at 400ºF for 15 minutes.
  7. Remove from oven and toss onions. Make an onion pile by using a spatula to scoot all of the onions together. This is to prevent crunchy onions. Then, flip the head of garlic over.
  8. Place back into the oven and bake at 400ºF for another 15 minutes. After 15 minutes, toss again. If your onions have reduced in size and turned a dark golden brown/dark purple color you know they are done. If your onions are still plump and light in color, they need to continue cooking.
  9. Once onions have caramelized, remove baking sheet from oven and immediately remove onions and garlic from the baking sheet. Set aside to cool.
  10. After the garlic head is cool enough to handle, use your hands to squeeze out the cloves into a large bowl. Then, use a fork to mash the roasted garlic into a paste.
  11. Add Greek yogurt, sour cream, and Worchestershire sauce to the bowl and mix.
  12. Before adding the onions to the bowl, use a pair of scissors to cut the onions into smaller, bite-sized pieces. Then, transfer caramelized onions into the bowl.
  13. Mix onions with the rest of the dip and do a little taste test to see if any more salt and/or pepper needs to be added.
  14. Serve with your favorite dipping vessel!
