Cooking Instructions

1. 01

   Make the caramelized onions

2. 02

   Melt the butter in a large nonstick skillet over medium-low heat.

3. 03

   Add the onions and toss to coat. Cook until the onions have softened, about 5 minutes, and add the thyme and red pepper flakes, if using. Continue caramelizing the onions, stirring them frequently so they brown evenly, for up to 60 minutes or more. (If the heat is too hot, the onions will burn, so slow it down and take some time to enjoy the process.) Season to taste with salt.

   Transfer the onions to a large bowl and set aside.Make the mustard aioli

5. 05

   Whisk the egg yolk, garlic, lemon juice, and mustard in a medium bowl to thoroughly combine. Start adding the canola oil, just a few drops at a time, whisking constantly, until the mixture begins to emulsify. As it thickens, continue adding the oil in a slow stream, making sure each addition is thoroughly blended before adding more. Season to taste with salt. Cover the aioli and refrigerate until needed.Assemble the sandwiches
