Instructions

It only takes a few easy steps to make this flavorful dip.

Step 1: Prep

Set your oven rack to the lowest position and preheat the oven to 400 degrees. Then, line a rimmed baking sheet with foil and coat it with nonstick spray.

Slice the onions in half crosswise – not lengthwise. Use a small, sharp knife to slice an “x” into each onion near the root and stem ends, allowing the steam to escape from the onion while it cooks.

Step 2: Roast the Onions

Coat the bottom of your onions with olive oil using a brush. Place them on top of the baking sheet, cut side down. Then, roast them until they’re dark brown around the bottom edges and tender when pierced with a knife tip.

Step 3: Prepare the Bacon

While the onions are roasting, cook the bacon in a skillet over medium heat until crisp. Transfer the bacon to a plate lined with paper towels to cool. Then, crumble.

Step 4: Cool the Onions

Transfer the pan to a cooling rack and let the onions rest for about 5 minutes before lifting them off the pan with a spatula.

Allow the onions to cool completely.

Step 5: Chop the Onions

When the onions have cooled, peel them and use a sharp knife to finely chop them.

Step 6: Make the Dip

Combine all the dip ingredients together in a medium bowl and mix until thoroughly combined.

Step 7: Chill

Transfer the dip to an air-tight container and chill for at least an hour before serving.

Hint: You can use a food processor to quickly chop your roasted onions. Just be sure that you don’t overdo it.

Tips

I have a few tips here that will help you make the best dip possible.

• Cook the bacon over medium heat. You want to get it crispy but not burned.
• When cutting the “x” into the stem and root ends of your onions, you only need to go deep enough to pierce the first layer or two of the onion. You don’t have to go super deep.
• If you use a food processor to chop your roasted onions, be careful not to overdo it. You want finely chopped onions, not onion puree.
