Ingredients
Method
- Prep the chicken: Slice chicken into thin strips for quick cooking. Pat dry with paper towels, then season lightly with salt and pepper.
- Mix the sauce: In a small bowl, whisk tamari or coconut aminos, rice vinegar, sesame oil, sweetener (if using), and red pepper flakes or sriracha. If using xanthan gum, sprinkle it in while whisking to avoid clumps. Set aside.
- Heat the pan: Place a large skillet or wok over medium-high heat. Add 1 tablespoon of avocado oil and let it get hot until shimmering.
- Sear the chicken: Add chicken in a single layer. Cook 4–6 minutes, stirring occasionally, until golden and just cooked through. Transfer to a plate.
- Cook the veggies: Add the remaining 1 tablespoon oil. Toss in broccoli, bell pepper, zucchini, mushrooms, and red onion. Stir-fry 4–5 minutes until crisp-tender. Season with a pinch of salt.
- Add aromatics: Stir in garlic and ginger. Cook 30–45 seconds until fragrant, stirring so they don’t burn.
- Bring it together: Return the chicken to the pan. Pour in the sauce. Toss to coat and cook 1–2 minutes until the sauce slightly thickens and everything is glossy.
- Taste and adjust: Add more tamari for salt, vinegar for brightness, or heat for spice. If too salty, a squeeze of lime balances it out.
- Serve: Spoon over warm cauliflower rice or shirataki noodles. Finish with sesame seeds and green onions.

Keeping It Fresh
Let the stir fry cool before storing. Portion into airtight containers, ideally separated from cauliflower rice to prevent sogginess. It keeps in the fridge for up to 4 days.
Reheat in a skillet over medium heat with a splash of water to loosen the sauce.
For freezing, skip the zucchini (it can get mushy) and slightly undercook the veggies. Freeze up to 2 months. Thaw overnight in the fridge and reheat on the stovetop.
Benefits of This Recipe
- Keto-friendly: Low in carbs and sugar, aligned with low-carb and ketogenic goals.
- High-protein, satisfying: Chicken provides steady energy without a crash.
- Veggie-packed: Fiber-rich vegetables help with fullness and texture.
- Customizable: Easy to adapt for spice level, ingredients on hand, or dietary needs.
- Quick cleanup: One pan, minimal mess, and simple prep.
Common Mistakes to Avoid
- Overcrowding the pan: This steams the chicken and veggies.
Work in batches if needed to keep the sizzle.
- Skipping the dry pat: Wet chicken won’t brown properly. Pat it dry before seasoning.
- Overcooking vegetables: Aim for crisp-tender. Soft veggies make the dish feel heavy.
- Using a sugary sauce: Many bottled sauces contain added sugar.
Stick with tamari, coconut aminos, and keto sweeteners.
- Adding aromatics too early: Garlic and ginger burn fast. Add them after the veggies have cooked.
Recipe Variations
- Spicy Garlic Chicken: Double the garlic, add extra red pepper flakes, and finish with a drizzle of chili oil.
- Lemon Pepper Twist: Add lemon zest to the sauce and finish with a big squeeze of lemon instead of lime.
- Peanut-Style (Keto): Whisk 1–2 tablespoons unsweetened peanut butter or almond butter into the sauce and thin with water as needed.
- Ginger Sesame: Increase ginger to 2 tablespoons and top with toasted sesame seeds and a splash of toasted sesame oil.
- Extra Veg: Swap or add snow peas (moderation), baby bok choy, cabbage, or asparagus for texture and freshness.
- Different Protein: Try thin-sliced beef, shrimp, or tofu (firm, pressed) with the same method.
FAQ
Is this stir fry truly keto?
Yes. It avoids noodles, added sugars, and starch thickeners.
The sauce uses tamari or coconut aminos and a keto-friendly sweetener, and you can serve it over cauliflower rice for a full low-carb meal.
Can I use regular soy sauce?
Absolutely. Use tamari for gluten-free, but regular soy sauce works if gluten isn’t a concern. Start with a bit less and add to taste since brands vary in saltiness.
How do I thicken the sauce without carbs?
A tiny amount of xanthan gum helps, but go light—too much gets gummy.
You can also simmer the sauce a minute longer to reduce naturally. Nut butter variations can add body as well.
What’s the best cut of chicken?
Chicken thighs stay juicier and are more forgiving. Breasts work well too; just slice thin and avoid overcooking to keep them tender.
Do I need a wok?
No.
A large, heavy skillet does the job. The key is high heat and not crowding the pan so you maintain that stir-fry sear.
How can I make it spicier?
Add more red pepper flakes, sugar-free sriracha, or a spoon of chili crisp (check labels for carbs). Taste as you go so the heat doesn’t overpower the sauce.
Can I make it ahead?
Yes.
Cook fully, cool, and store in the fridge. Reheat on the stovetop for best texture, and keep cauliflower rice separate until serving.
What can I use instead of xanthan gum?
Just reduce the sauce in the pan for a minute or two. It will thicken slightly and cling to the chicken and veggies without any thickeners.
How do I keep the veggies crisp?
Cook over high heat, keep pieces similar in size, and stop when they’re just tender.
A quick stir-fry prevents sogginess and keeps color bright.
Is coconut aminos OK for keto?
Yes, in moderation. It’s a bit sweeter and lower in sodium than soy sauce. Track your macros if you’re strict, but it’s commonly used in keto cooking.
