It’s so easy to make this wonderfully tender and flavorful beef thanks to the slow cooker. It’s such a great way to cook the beef with minimal effort. The broth is delicious too! Poured over the sandwiches and any leftover can be used for beef au jus sandwiches.
Can you make these open faced sandwiches ahead of time?
The sandwiches are best served as soon as they are made so that the bread doesn’t get soggy. However, you can easily make all of the components ahead of time.
- Beef: The beef can be made up to four days in advance and kept in the fridge in an airtight container. The jus can be stored separately.
- Mashed potato: Use my make ahead mashed potato recipe that can be made two days in advance.
- Toast: You can even pre toast the bread! Keep it in an airtight container for up to 4 days.
How do you slice the beef for these sandwiches?
Slice the beef in relatively thin slices. It’s easiest to cut the beef after it has been refrigerated for some time, but that isn’t necessary if you want to eat the sandwiches right away. For this recipe, we cut the beef right away while still warm. Since you’re eating this meal with a fork, its not as necessary that the beef is in neat slices.
