Can I use a different cut of beef?
Yes, but some cuts will cook differently. Round steak or chuck roast would be tougher cuts that would benefit from the long cook time in the crockpot. Tri-tip or skirt steak can be substituted but may cook faster.

What can I use instead of mushrooms?
You can omit the mushrooms entirely, or substitute with another vegetable you like, such as zucchini, broccoli florets, or chopped carrots.

I don’t have beef broth. Can I use something else?
Yes, you can substitute chicken broth or water with an additional tablespoon of soy sauce for added flavor.

Can I add other vegetables to this recipe?
Yes, absolutely! See above for some suggestions.

How can I make this spicier?
Add a pinch of red pepper flakes to the sauce mixture, or serve with a side of sriracha sauce.
