Grilled Sour Cream and Onion Dip is an easy no-hassle appetizer recipe made with pantry staples. Roasted on the grill, the onion and garlic become a caramelized dream and make this onion dip addictingly delicious!



  • 1 medium-sized yellow onion
  • 4 garlic cloves, peeled and halved
  • 2 TBSP unsalted butter, cubed
  • 1/2 tsp garlic powder
  • 3/4 tsp onion powder, divided
  • 1/2 tsp kosher salt
  • 3/4 cup sour cream
  • 1/4 tsp + few splashes Worcheshire sauce
  • Additional salt and pepper, to taste


  1. Preheat oven or grill to 450°F. Prepare the onion by cutting off the top and bottom, and removing the outer layer. Cut 4 slits in the onion top, going about halfway through. Cut out the center of the onion, about 1 inch deep. Place the prepared onion on a piece of foil large enough to wrap around the entire onion.
  2. Gently peel back several layers of the onion and place 4 garlic cloves inside the onion layers and on top of the onion as best as possible. Place the butter, 1/2 tsp onion powder, garlic powder, salt and pepper on top of the onion.  Wrap the foil around the onion.
  3. Place the foil packet on the top rack of the grill or in the middle of the oven. Roast for 25-35 minutes, until tender. Remove from heat, open foil, and let cool. 
  4. Once the onion is cooled enough to handle, drain the remaining liquid into a bowl. Chop the onion and garlic to the desired size for the dip.
  5. Whisk together excess liquid with sour cream, Worcheshire sauce, 1/4 tsp onion powder, salt, and pepper. Taste to adjust salt/pepper/onion levels as needed and add the chopped onion and garlic, stirring until combined. Chill in an airtight container until ready to serve (you can serve immediately but I personally like it chilled). Serve with potato chips and enjoy!
