You want lean, fast, and flavorful? This is the move. Crispy high-protein tofu, a flood of colorful veggies, and a sauce that tastes like takeout without the sugar trap.
It’s the kind of meal that makes you forget you’re “being good” because it slaps on taste and hits your macros. No bland diet vibes, no rabbit food energy—just a skillet, a plan, and a plate you’ll make on repeat. Ready to eat like you mean it?
Why This Recipe Works

This stir fry nails the trifecta: high protein, low carbs, big flavor.
Extra-firm, high-protein tofu browns beautifully and keeps its structure, so you get that satisfying chew—no mush. Non-starchy veggies like broccoli, bell peppers, and zucchini bring volume, fiber, and crunch with minimal carbs.
The sauce is built for balance: umami-rich tamari, ginger for brightness, garlic for punch, and a touch of rice vinegar to wake up the palate. A whisper of sesame oil at the end adds depth without weighing the dish down.
Translation: you’ll crush cravings, stay full, and still feel light enough to move.
Shopping List – Ingredients
- 14–16 oz high-protein extra-firm tofu, pressed and cubed
- 2 cups broccoli florets
- 1 red bell pepper, sliced
- 1 small zucchini, halved and sliced
- 1 cup sugar snap peas, trimmed
- 4 cloves garlic, minced
- 1 tbsp fresh ginger, grated
- 3 tbsp tamari or low-sodium soy sauce
- 1 tbsp rice vinegar
- 1–2 tsp chili-garlic sauce or sambal (optional heat)
- 1 tsp toasted sesame oil
- 2 tbsp avocado or peanut oil (for high-heat stir-frying)
- 1–2 tsp low-carb sweetener (monk fruit, allulose, or skip)
- 1/4 cup vegetable or chicken broth (low-sodium)
- 1 tsp arrowroot or 1/2 tsp xanthan gum (optional thickener; keep it light)
- 2 green onions, sliced
- 1 tbsp sesame seeds (garnish)
- Fresh lime wedges (optional finish)
Step-by-Step Instructions

- Press the tofu: Wrap tofu in paper towels, place a pan on top, and press for 10–15 minutes to remove excess moisture. Cube into 3/4-inch pieces.
- Prep the veggies: Slice bell pepper, zucchini, and trim snap peas. Break broccoli into bite-size florets.
Mince garlic and grate ginger.
- Make the sauce: In a bowl, whisk tamari, rice vinegar, chili-garlic sauce, sweetener, broth, and sesame oil. If using a thickener, whisk it in now (arrowroot/xanthan). Set aside.
- Crisp the tofu: Heat 1 tbsp oil in a large skillet or wok over medium-high.
Add tofu in a single layer. Cook 6–8 minutes, turning occasionally, until golden on most sides. Remove to a plate.
- Stir-fry the veg: Add remaining 1 tbsp oil.
Toss in broccoli and snap peas first (2 minutes), then bell pepper and zucchini (2–3 minutes). You want bright color and a tender-crisp bite.
- Aromatics in: Push veggies to the sides. Add garlic and ginger to the center and sauté 30 seconds until fragrant.
No burning allowed, unless you enjoy sadness.
- Combine: Return tofu to the pan. Pour in sauce. Toss and cook 1–2 minutes until everything is glazed and the sauce slightly thickens.
- Finish: Kill the heat.
Stir in green onions, sprinkle sesame seeds, and squeeze lime if you like a tangy pop.
- Serve: Plate as-is or over cauliflower rice for extra volume, still low carb. Thank yourself.
Storage Tips
- Refrigerate: Store in an airtight container for up to 4 days. Keep cauliflower rice separate if using.
- Reheat: Skillet over medium heat with a splash of broth to revive the sauce.
Microwave works in a pinch (60–90 seconds), but tofu stays crispier in a pan.
- Freeze: Not recommended. Tofu texture and veggie crunch suffer. If you must, freeze sauce separately and cook fresh veg and tofu later.

Nutritional Perks
- High protein: High-protein tofu packs ~22–28g protein per 8 oz.
This recipe hits that satiety sweet spot without meat.
- Low carb, high fiber: Non-starchy veggies keep carbs in check while fiber steadies blood sugar. Win-win.
- Healthy fats: Minimal oil plus sesame notes equals flavor without overload.
- Micronutrient-rich: Broccoli for vitamin C and K, peppers for antioxidants, and ginger for digestive support. Basically your multivitamin in wok form.
Common Mistakes to Avoid
- Skipping the press: Wet tofu won’t crisp.
It will steam, sulk, and disappoint.
- Overcrowding the pan: Too many veggies equals soggy stir fry. Work in batches if needed.
- Overcooking the vegetables: Color fading = nutrients and texture leaving the chat.
- Using too much thickener: You want glossy, not gravy. Start small.
- Forgetting acid: A touch of vinegar or lime is the difference between “fine” and “whoa.”
Recipe Variations
- Spicy Szechuan: Add 1 tsp Szechuan peppercorns and extra chili-garlic sauce.
Toss in shredded cabbage.
- Ginger-Scallion: Double the ginger, add extra green onions, and skip the sweetener. Clean, sharp, and aromatic.
- Peanut Crunch: Stir 1 tbsp natural peanut butter into the sauce and finish with crushed roasted peanuts. Still low carb; watch portions.
- Thai-ish Basil: Add Thai basil at the end with a squeeze of lime and a few drops of fish sauce (or keep it vegan with more tamari).
- Keto Max: Drop the zucchini and bell pepper, double broccoli and mushrooms.
Use xanthan gum only, no arrowroot.
- Air-Fryer Tofu: Toss tofu with 1 tsp oil and a pinch of salt; air-fry at 400°F (205°C) for 12–14 minutes, shaking halfway. Then stir-fry veg and combine.
FAQ
How do I keep tofu from sticking to the pan?
Use a well-heated skillet or wok and a high-smoke-point oil. Add tofu only when the oil shimmers, and don’t move it for 2–3 minutes to let a crust form.
A good nonstick or well-seasoned carbon steel pan makes life easier, FYI.
Can I swap tamari with coconut aminos?
Yes. Coconut aminos are sweeter and less salty, so reduce or skip the added sweetener and add a pinch of salt to balance. You may need a splash less broth to avoid diluting flavor.
What’s the best low-carb side?
Cauliflower rice is the go-to.
For more texture, try “riced” broccoli or a shredded cabbage sauté. If you’re not strict low carb, a small portion of quinoa works, but that’s your call.
Do I need a wok?
Nope. A large skillet with high sides works.
The real key is high heat, dry veggies, and not overcrowding. Technique beats gear, IMO.
Can I make this soy-free?
Use extra-firm chickpea tofu (burmese tofu) or firm tempeh made from lupin/peas, and swap tamari for coconut aminos plus a pinch of salt. Flavor stays big, soy stays out.
How spicy is this?
Base recipe is mild with optional heat.
Add chili-garlic sauce to taste, or finish with red pepper flakes if you’re chasing that endorphin rush.
Will this fit into a keto diet?
Yes, with tweaks: skip sweeteners that add carbs (use liquid stevia if needed), avoid arrowroot (use a pinch of xanthan), and choose lower-carb veg like broccoli, snap peas in moderation, and mushrooms. Keep portions aligned with your macros.
My Take
This Low Carb Vegetable Stir Fry with High Protein Tofu is what I make when I want maximum payoff with minimal effort. It eats like comfort food but performs like a meal prep pro—fast, balanced, and repeatable.
The tofu crisps, the veggies pop, the sauce hums with umami, and you don’t miss the carbs for a second. Make it once, tweak to your taste, and you’ve got a weekday staple that makes “healthy” feel like a flex, not a chore.
