FAQs & Tips

What is udon soup?

Udon soup is Japanese noodle dish made with thick, wheat noodles (udon). It’s usually  served in a savory broth with protein like beef, chicken, or even shrimp.

What type of beef should you use?

This beef udon soup calls for thinly sliced beef. Personally, I like to use shaved beef for this recipe. Other options include beef sirloin or flank steak cut thin.  

Can you add different vegetables?

Of course. In fact, I encourage you to use your favorite vegetables like mushrooms or snap peas.

Can you use frozen udon noodles?

You can! No need to change anything in the recipe, just add the frozen noodles at the end. 

Can you use a different type of noodle?

Well, this is a beef udon noodle soup recipe but technically you can use whatever type of noodle you want. In place of the udon, I suggest ramen noodles as a substitute. 

How do you store leftovers?

Store leftover slow cooker beef udon soup in the refrigerator for up to 4 days. 

What size slow cooker did you use?

I use a  6-quart slow cooker or Instant Pot for this recipe.
