Instant Pot Glazed Corned Beef Sandwiches to celebrate St. Patrick's Day. Finished with molasses based sweet sultry glaze to compliment the saltiness of the corned beef.
Rinse corned beef under cold water. Place the corned beef, fat side up, in the bottom of an Instant Pot. Sprinkle on the seasoning packet and pour in 1 cup cold water. Place lid on Instant Pot and set to cook on high pressure for 80 minutes.
For the glaze. Mix together the mustard, horseradish, vinegar and molasses. Set aside.
When corned beef is done, unplug the Instant Pot and let the steam naturally release for 10 minutes. Then press the steam valve to release the remaining steam. Remove from Instant Pot to a sheet pan. With a brush, liberally baste the corned beef with the glaze.
Preheat oven to 375 - 400 degrees. I use 375 because my oven runs hot. If the oven is too hot, the glaze will smoke leaving it with a bitter flavor. Place the brisket in the oven, cook for 15 minutes basting with glaze every 5 minutes.
Remove brisket from oven and place the brisket on a cutting board. Let rest for 10 minutes, or 1 hour ideally. Switch oven temperature to broil.
With a sharp knife, (not serrated) slice the meat against the grain. Place chunks of corned beef onto the bottom of slider buns. Top with slices of Swiss cheese. Add a small drizzle of additional glaze if you'd like.
Broil briefly until cheese is melted. Top with the other half of the slider bun.
Notes
I used Tillamook Swiss Cheese Slices. Fold and divide each slice into 4 equal pieces worked good for the size of the slider buns.
