Recipe Notes
I use hot sesame oil for heat. Feel free to use regular sesame oil if you don't like it too spicy.
I love the sound of this, I’d be able to use wheat or rice noodles instead if I couldn’t find the sweet potato ones right? This is perfect weeknight cooking!
You can definitely substitute with wheat or rice noodles. Thanks for stopping by and I hope you’ll give it a try.
I’ve never cooked with sweet potato noodles. Do they come in a block like ramen, or separated like spaghetti? Do you know where to buy them?
Hi Rebekah,
They’re glass noodles, usually dry and comes in chunks, but you can separate them by hand. You can find them in rice/ noodles section in international markets. Here’s a link on amazon. Hope you’ll give it a try.
