Tips & Tricks

This roasted garlic caramelized onion dip is so easy to make, but here are some tips and tricks to bring out the flavor and full potential of this delicious dip.

It’s All About the Onions. It is obvious that onion is the star of this dip, but how you prepare an cook the onions is very important. Here are a couple things to keep in mind.

  • Do not slice the onions too thin. Keep the onions 1/4-1/2 of an inch thick.
  • Make sure all of the onions are covered in olive oil and the spices.
  • Most importantly, when roasting the onions, be sure they are all touching each other! If there are any outliers on the pan, they could burn!

Greek Yogurt OptionsThere are so many different options when you are in the greek yogurt isle and guess what, most of them will work for this dip! Most importantly, you want to make sure you buy a plain greek yogurt.

We love full buying full fat Greek yogurt, but any plain greek yogurt will do, as well as some plain vegan yogurts! Feel free to by 0%, 2%, or 5% plain greek yogurt.

Roasted Garlic Ins-and Outs. Wow, have you tried garlic that is roasted in a bulb with olive oil and salt? It is absolute heaven. If you don’t have a full garlic bulb, that is ok, you can roast garlic cloves too! Just be sure you roast it in the oven with the onions for full flavor potential!

Add Fresh Herbs. After the dip is finished, be sure to sprinkle the dip with fresh herbs! It really does complete the dip. Our first choice is fresh thyme, but feel free to try fresh basil, fresh parsley, or even fresh tarragon for a fun twist!

How to Store Onion Dip. Store the onion dip in an airtight container in the refrigerator for up to 5 days.

  • Prep Time: 15 minutes
  • Cook Time: 30 minutes
  • Total Time: 45 minutes
Author: Lee Funke
Yield: 4-6 1x
Category: Dip
Method: Oven
Cuisine: American


  • 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!
