These tofu soba noodles with bok choy are tossed in a sweet, spicy miso garlic ginger sauce that coats the noodles and crispy bites of tofu. It feels like takeout but comes together in about 30 minutes with simple ingredients.

More Soba Please!
Soba noodles are probably my favourite noodle. They have the best texture and always feel like such as satisfying, yummy meal. I also have these Cold Soba Noodle Salad and Cold Buckwheat Noodles, both are delicious!
Ingredients You’ll Need
Below is a quick overview of what you’ll need to make the recipe and any substitutions you can make. Use the recipe card with the full list of ingredients and measurements at the bottom of the post when you’re ready to make the recipe.

- Tofu: Firm or extra-firm tofu is best.
- Soy Sauce: Use gluten-free tamari or coconut aminos to make the recipe gluten-free.
- Sesame Oil: Toasted or regular sesame oil is suitable.
- Cornstarch: You can substitute arrowroot starch. This helps give the tofu a crispy coating.
- Soba Noodles: I love the Hakubaku Soba Noodles but any soba (buckwheat noodles) works.
- Shelled Edamame: Frozen shelled edamame is perfect! You could substitute chickpeas if needed.
- Miso Paste: White or yellow miso paste works.
- Bok Choy: Bok choy or baby bok choy works or you can use snap peas, broccoli, mushrooms or another Asian green.
- Maple Syrup: You could substitute honey if needed.
- Cucumber and Radish: Optional but a nice, fresh and pretty topping!
Variations
- This recipe would also be good with the peanut sauce from these Tofu Peanut Bowls or teriyaki sauce from these Chickpea Teriyaki Bowls.
- If you want to do extra veggies, mushrooms, broccoli, thinly sliced carrot, snow peas, snap beans, bell pepper and onion all work well. You can stir fry them with the bok choy and remove from pan, then either mix in with noodles and tofu or serve on top of the final dish.
Deryn’s Tips
- Rinse the soba and edamame under cold water after cooking stop cooking and prevent them from sticking.
- Review the recipe steps before you start. There are a few things to do but once you have a good idea of the flow it all comes together quick!
- To make it easier to eat, you can chop the bok choy into bite-sized pieces before or after cooking.
