I got a little creative in the kitchen trying to figure out how to use my leftover Beer Braised Brisket and here's what I came up with!
You may have seen my recipe for Beer Braised Brisket using one of my favorite beers, Left Hand Nitro Milk Stout. I recently made it for a family gathering and had a lot leftover that I squirreled back with me to Brooklyn and did what I do best--came up with a new recipe!
I pickled some red onions and made my own horseradish aioli and boom...delicious leftover brisket sandwich.
- 4 Kaiser rolls
- Leftover brisket (see my recipe for Beer Braised Brisket here!) -- about 1 pound
For pickled onions:
- 1 large red onion
- 1 cup red wine vinegar
- 1 tablespoon sugar
- 1 cup water
- 1 1/2 teaspoons kosher salt
For horseradish aioli:
- 1/2 cup mayonnaise
- 1/2 teaspoon prepared horseradish
- 1 garlic clove, minced (you can substitute garlic powder here too--about 1/8 teaspoon)
- Kosher salt to taste
Step 1. You'll want to start by pickling the onions first--they take at least an hour but I prefer to do them a day in advance! Cut the onion in half then remove the first layer of skin. Cut the onion into thin slices. Place onion slices into a mason jar (or a sealed container).
Step 2. Combine the vinegar, sugar, salt and water in a bowl until the sugar and salt dissolve. Pour the mixture over the onions in the jar/container, seal, and let sit for at least an hour up to 2 weeks.
Step 3. To make the horseradish aioli, just combine the mayonnaise, horseradish, and minced garlic (or garlic powder) and season with salt.
Step 4. Heat up the brisket either in a large pot or skillet (basically avoid the microwave if possible!). Assemble each Kaiser roll with about a quarter pound of brisket, pickled onions, and a generous amount of horseradish aioli and enjoy!
Tip: You can also turn this into a panini by adding your favorite cheese (I would go with either Swiss or Gouda here)!
If you don't have a panini press, don't worry, just spray some PAM on a skillet or cast-iron grill and use a heavy pot to hold the sandwich down on each side until you get nice grill marks and the cheese melts!
