This sandwich recipe is delicious year-round. But football season is the perfect excuse for easy sous vide sausage and onions on hoagie rolls. They are inexpensive to make and you can sous vide them in bulk. The result is a sandwich more flavorful than the kind they sell at the stadium. Win-win!

Don’t have a sous vide machine yet? You can boil or fry the sausages on the stove. But, nothing beats a sous vide! 

Serve sous vide sausage and onions on a hoagie for the ultimate game day sandwich.

There’s a sausage for every foodie. Some of the most popular varieties are Polish, Italian, and Spanish chorizo. They all taste great with onions and dijon mustard. Cooking them sous vide style guarantees they won’t dry out.  

The prep for this dish is quick. After a few minutes on the stove, the sausages and onions cook sous vide style for two hours.

As the onions sweat in the sous vide bag, the flavors mix with the “beer juice”. After the sous vide process is complete, the liquid and onions simmer for a few minutes in a pan to finish off.

The sausages are fried on the stove or in a grill pan while the hoagie rolls toast in the oven.
