  • Combine the garlic, egg, lemon juice and parsley in a blender. Puree. Salt and pepper to taste. Add the oil in slowly and continue to process the mixture until it forms a thick emulsion.
  • Caramelized Onion Recipe

  • Melt the butter in a large frying pan over medium-low heat. Add the onions and cook, stirring rarely, until they are deep golden brown. It will take about 45 minutes for them to be caramelized. Season well with salt and pepper, remove from the pan and cool.

  • Cooking Directions

    To assemble the tartine:

    Toast the slices of bread in your toaster. Spread a layer of the garlic aioli on each slice. Top with caramelized onions. The filet should be cooked medium rare with olive oil, salt and pepper. Then cool the filet and slice it thinly. Separate the sliced filet among the 2 tartine sandwiches. Top with the arugula salad and sliced radishes.
