I just got back from Red Robin myself and discovered this. It is amazing! Here is the best recipe I could find to recreate it.
6 strips Bacon, thick cut, sliced into 1/2 inch pieces
1 Egg Yolk
1⁄4 cup Sherry Vinegar
1 cup Oil, blended - half canola, half olive oil
1 teaspoon Honey
1 tablespoon Dijon Mustard
Freshly Ground Black Pepper
Step 1 Heat a large skillet over medium heat. Add bacon; cook until crisp, 7-10 minutes. Transfer bacon to paper towel lined plate. Pour off some of the fat.
Step 2 Put yolk, vinegar, mustard and honey in a blender. Pulse several times to combine. Drizzle in the oil with blender running until all has been incorporated and a thick emulsion forms.
Step 3 Crumble the bacon; reserve some for garnish. Add remaining bacon to blender; blend until smooth. Season with salt and pepper to taste.
