Seitan Broccoli Soba – 34g Protein | Vegan Lunch

34 grams of protein in one colorful bowl. This is what I make when I need serious fuel after a workout or a long day. The seitan gets crispy on the edges, the broccoli stays bright green, and those carrot ribbons add a pop of sweetness against the savory ginger-garlic glaze.

The key to this dish? Rinsing the soba noodles in cold water immediately after cooking. I know it sounds fussy, but skip this step and you’ll have a sticky, gummy clump within minutes. This 10-second rinse is what separates “restaurant stir-fry” from “disappointing takeout.”

⏱️ Time: 20 minutes (Prep: 5 | Cook: 15)
🍽️ Serves: 1

INGREDIENTS:

• 60g (approx. 2 oz / 1 bundle) buckwheat soba noodles
• 100g (approx. 3.5 oz) seitan strips
• 200g (1½ cups) frozen broccoli
• 1 medium carrot (approx. 60g), shaved into ribbons
• 1 tsp sesame oil (for cooking)
• 1 tsp olive oil
• 1 tbsp (15ml) lemon juice
• 1 clove garlic, minced
• 1 tsp fresh ginger, grated
• Red pepper flakes, to taste
• Sesame seeds, for garnish

INSTRUCTIONS:

1. Cook the noodles properly: Boil soba for 4-6 minutes according to package instructions. Here’s the crucial step – as soon as you drain them, immediately rinse under cold running water while tossing with your hands. This stops the cooking and rinses off excess starch. Soba is very high in starch; if you don’t rinse, the noodles will turn into a sticky clump within minutes. Set aside.
2. Get the seitan crispy: Heat sesame oil in a large pan or wok over medium-high heat. Add seitan strips in a single layer – don’t crowd them. Let them sit undisturbed for 2 minutes to develop a golden crust, then flip and crisp the other side. You want actual color and texture here, not just warmed-through seitan.
3. Steam the vegetables: Add frozen broccoli and carrot ribbons to the pan with 2 tablespoons of water. Immediately cover with a lid and let steam for 2 minutes. The water creates steam that cooks the broccoli through while keeping it bright green. Remove the lid and let any remaining water evaporate.
4. Build the flavor base: Push everything to the sides of the pan, creating a clear space in the center. Add olive oil to that center spot. Add minced garlic and grated ginger. Let them sizzle in the hot oil for about 30 seconds until incredibly fragrant. Watch carefully, garlic can burn fast!
5. Bring it together: Toss everything in the pan to coat with that ginger-garlic oil. Add the rinsed soba noodles and lemon juice. Toss vigorously for about 1 minute until the noodles are heated through and everything is well combined.
6. Finish: Season with red pepper flakes and sesame seeds.

PRO TIP: Rinsing soba in cold water isn’t optional! Soba noodles are incredibly high in starch compared to other noodles. If you don’t rinse them immediately after cooking, that surface starch will cause them to stick together into an impossible-to-separate mass. The cold water rinse removes excess starch and stops the cooking process, giving you separate, glossy noodles that toss beautifully in a stir-fry.

CHEF’S KISS: Finish with a handful of sliced scallions (green parts only) scattered on top right before eating. The fresh, sharp bite of raw scallion cuts through the richness of the sesame oil and adds a restaurant-quality finish. If you want to go full restaurant-style, add a tiny drizzle of chili oil on top for heat and visual appeal. Impact: Scallions and chili oil = +15 calories, +0g protein, but restaurant-level presentation and flavor.

You may find yourself in need of: 

Carbon Steel Wok – makes it easier to push ingredients aside, build the ginger-garlic base in the center, then toss everything together quickly.

Toasted Sesame Oil  – helps crisp the seitan while adding that subtle, nutty backbone to the glaze.

Buckwheat Soba Noodles – cook briefly, rinse well, and they stay firm even after reheating.
