In a large pot, add Olive Oil, Onion, Garlic, Beans (dry, not soaked), Barley, Potatoes, Beef. Mix thoroughly to coat everything with the oil.
Add Beef stock and Stir.
Add Chulent Spice, Deli Mustard, Ketchup, Maple Syrup, Kosher Salt, Black Pepper. Stir until spices are evenly distributed.
Top with Water.
Bring to a boil on the stovetop, cover and reduce heat to Medium.
Simmer for an hour, then stir. Add water if necessary. The beans and barley will absorb the liquid, so you need to keep this wet otherwise they will come out hard.
Simmer an additional 30 minutes.
Stir, add water if necessary. If you are adding a kishke, this is the time. Wrap your kishke in foil and push it down into the center of the chulent.
