Prepare the remoulade. In a bowl, combine the mayonnaise, Dijon mustard, Cajun seasoning, and salt and pepper (to taste). Cover and refrigerate.
In a bowl, combine the shrimp, 1 tbsp olive oil, 1 tsp Cajun seasoning, sea salt and a few grinds of black pepper. Cover with plastic wrap and set aside.
Make three burger patties, seasoning them with sea salt and pepper. Cook the burgers in a skillet to at least 165 degrees. When done cooking, place a slice of Muenster and Swiss cheese on each burger and allow to get melty. Then, remove the burgers from the skillet and set aside to rest. Tent burgers with foil.
While the burgers cook, spread 2 tbsp butter over the cut sides of each bun with butter, and then toast them in the oven.
In a skillet, over med-high heat, cook the shrimp in 2 tbsp of butter, for about 3 minutes on each side.
Cook the purple onion in 1 tbsp olive oil over med-high heat for 15-20 minutes. You don’t need to fully caramelize them, just soften and even scorch a bit.
Build the burger! Feel free to add hot sauce at any point. On bottom buns, spread with remoulade and place lettuce and tomato on top. Then add a cheesy burger patty to each bun, followed by 4 shrimp on each. Place cooked onion over the shrimp, then top the whole thing off with the top bun halves, which have remoulade spread on them.
Enjoy!
Points to Consider
Muenster cheese melts easily and goopy, which is good.
You can prepare this on a grill, as well.
This recipe works best if you can be cooking the burgers, shrimp and onions all at the same time.
Feel free to add ingredients / seasonings of preference.
The USDA says to cook shrimp to 145 degrees, but some chefs say less.
