The idea for this recipe is simple: Use the traditional method for making mayonnaise, but substitute bacon fat for the oil. It’s an easy way to use up leftover bacon fat that’ll yield a tasty spread for the bacon-obsessed. Use it to up the pork factor of your BLT, or go whole hog with our Triple-Pork Club Sandwich.

Game plan: Once made, the mayonnaise should be refrigerated in an airtight container; it will last up to 4 days.

  • Yield: 1 cup
  • Difficulty: Easy
  • Total: 30 mins

Ingredients (7)

  • 16 thick-cut bacon slices (about 1 pound 4 ounces), cut in half crosswise
  • Vegetable oil, as needed
  • 4 large egg yolks
  • 2 teaspoons cider vinegar
  • 1 teaspoon Dijon mustard
  • 1/2 teaspoon kosher salt
  • 1/4 teaspoon freshly ground black pepper

Instructions

  1. Heat the oven to 425°F and arrange two racks to divide the oven into thirds.
  2. Arrange the bacon pieces in a single layer on 2 rimmed baking sheets. Bake for 10 minutes. Rotate the pans between the racks and continue baking until the bacon is crisped and brown, about 5 to 10 minutes more.
  3. Transfer the bacon pieces to a large paper-towel-lined plate, placing additional paper towels between each layer of bacon. Carefully pour the bacon fat from the baking sheets into a heatproof measuring cup—you need 2/3 cup. (If you don’t have enough bacon fat, add vegetable oil as needed.) Discard any excess bacon fat. Let the measured bacon fat cool for 15 minutes.
  4. Place the egg yolks, vinegar, and mustard in a medium bowl and whisk until combined. While whisking constantly, very slowly add the bacon fat or bacon fat–oil mixture in a thin stream until it’s completely incorporated and the mixture is thickened and creamy. Add the salt and pepper and whisk to combine; use immediately or refrigerate for up to 4 days.
