These 30-Minute Ginger Beef Sweet Potato Noodles are so delicious! Use spiralized sweet potato noodles for an easy low carb meal.
Ingredients and substitutions
- Steak – use fast-fry beef strips, chicken or tofu. If you use chicken, you’ll need to cook it for 8 minutes.
- Baking soda – this will help tenderize the meat, so you can leave it out, but the steak won’t be as tender.
- Cornstarch – potato starch would be a good substitute here.
- Sweet potato – you can buy pre-spiralized sweet potato noodles or spiralize another veggie like zucchini, butternut squash or beets.
- Broccoli – cauliflower would also be good or you can swap out for another veggie of your choice.
- Mushrooms – use any variety of mushrooms or another veggie.
- Red pepper – yellow, orange or green peppers can be used instead.
- Scallion – swap out for yellow or white onions if you don’t have any scallions.
Stir fry sauce
- Soy sauce – coconut aminos or tamari are the best substitutes for soy sauce.
- Sesame oil – you can use a neutral cooking oil like olive oil but it will have a milder flavour.
- Garlic – freshly minced garlic is best but jarred minced garlic will work in a pinch.
- Ginger – use a bit of ground ginger instead.
- Sriracha – leave this out altogether if you’re not a fan of spice.
- Sesame seeds – black or white sesame seeds would be good garnishes.

Spiralizing sweet potato noodles
I may have cheated a little and bought some pre-spiralized sweet potato noodles at the store. When I'm in a rush or don't have too much time to chop and prep veggies, I love grabbing some pre-packaged veggies. Anything from chopped and peeled butternut squash to spiralized zucchini, different veggie blends and cauliflower rice make meal time so much easier!
You can also spiralize the sweet potato at home using a spiralizer, which makes sweet potato noodles recipes a breeze. You'll want to peel the sweet potato first, then attach the sweet potato between the two prongs of the spiralizer and push it through. You'll have strands of sweet potato noodles in no time! You can even spiralize them up to 2 days in advance so all you have to do is add them to your stir fry at the last minute.
Frequently Asked Questions
Any type of spiralized vegetable will cook much quicker than regular noodles, so you're only going to sauté these sweet potato noodles for 2 minutes or so. I use high heat so that they will maintain their crunch but also become a little bit tender. Because this is a stir fry sweet potato noodles recipe, you'll want to use a large skillet on high heat or a wok so that your vegetables become tender-crisp. This will also help to thicken the sauce.
If you don't have a spiralizer, you can use a julienne peeler to make the sweet potato noodles. You can even buy pre-spiralized noodles at the grocery store to cut down on prep time!
Yes! If you want to make this sweet potato noodles recipe vegetarian, swap out the beef for tofu to make delicious ginger tofu noodles.
You can store the cooked sweet potato noodles in the fridge in an airtight glass container for 2 to 3 days. Anything more than that and the noodles will start to get soggy.
Storing and reheating
This sweet potato noodles recipe makes great leftovers, but you need to eat them within 2 to 3 days or they’re get soggy. Instead of reheating in the microwave, I'd recommend reheating in a large skillet over high heat on your stove. This way you can revive the dish and add a bit of crunch back in – if you reheat the stir fry in the microwave, you risk the noodles getting soggy.
Freezing this recipe
Unfortunately, you can't freeze this cooked dish, but you can freeze the steak in the marinade! This way, part of the recipe is already done for you and you can just get on with cooking it. Freeze it in a Ziploc bag for up to 3 months. When you’re ready to use it, just let it defrost in the fridge overnight then serve it with some fresh sweet potato noodles.
