Easy Keto Chicken Stir Fry Dinner – Fast, Flavorful, and Low-Carb
This is the kind of weeknight meal that makes you feel like you’ve got things under control. Tender chicken, crisp veggies, and a glossy, savory sauce—all ready in about 25 minutes. No complicated steps, no hard-to-find ingredients, and definitely no heavy carbs.
It’s flexible, too, so you can use what you already have in the fridge. If you want something healthy, satisfying, and unfussy, this stir fry hits the spot.
Ingredients
Method
- Prep everything first. Stir fry moves fast. Slice the chicken and vegetables, mince the garlic, grate the ginger, and mix the sauce ingredients in a small bowl. Taste and adjust salt or sweetness now.
- Heat the pan. Use a large skillet or wok over medium-high heat. Add 1 tablespoon of avocado oil and let it shimmer.
- Cook the chicken. Add the chicken in a single layer. Season lightly with salt and pepper. Stir fry 4–6 minutes until just cooked through and lightly browned. Remove to a plate and keep warm.
- Stir fry the sturdy veggies. Add the remaining 1 tablespoon oil. Toss in broccoli florets and the whites of the green onions. Cook 2 minutes, stirring often.
- Add the tender veggies. Add bell pepper, zucchini, and mushrooms. Cook 2–3 minutes until crisp-tender. You want color and a slight bite, not mush.
- Aromatics in. Push the veggies to the sides, add garlic and ginger to the center, and cook 30 seconds until fragrant.
- Combine and sauce. Return chicken and any juices to the pan. Pour in the sauce. Toss to coat everything evenly.
- Thicken if you like. If you prefer a glossy, thicker sauce, lightly sprinkle xanthan gum over the pan while tossing. Start with a pinch. It thickens quickly—don’t overdo it.
- Finish and serve. Turn off the heat. Stir in the green onion tops. Garnish with sesame seeds. Serve as is or with cauliflower rice for a full meal.
Why This Recipe Works
- Quick cooking method: Stir frying uses high heat to lock in flavor and keep vegetables crisp, so everything tastes fresh, not soggy.
- Simple, clean ingredients: Chicken thighs or breasts, low-carb veggies, and a smart sauce give you big flavor with minimal effort.
- Keto-friendly sauce: A balance of coconut aminos or tamari, garlic, ginger, and a touch of sesame oil keeps carbs low without sacrificing taste.
- Easy to customize: Swap vegetables based on what you like or what’s in season, and adjust the heat level to your taste.
- Meal-prep friendly: Makes great leftovers that reheat well, so tomorrow’s lunch is handled.
Ingredients
- 1.5 pounds boneless, skinless chicken (thighs for juiciness or breasts for leaner protein), thinly sliced
- 2 tablespoons avocado oil (or light olive oil), divided
- 1 small head broccoli, cut into bite-size florets
- 1 red bell pepper, thinly sliced
- 1 small zucchini, halved lengthwise and sliced
- 1 cup sliced mushrooms (cremini or button)
- 3 green onions, sliced (whites and greens separated)
- 2 cloves garlic, minced
- 1 tablespoon fresh ginger, grated
- Sesame seeds (optional, for garnish)
For the sauce:
- 1/3 cup coconut aminos (or tamari for gluten-free; note tamari is saltier)
- 1 tablespoon rice vinegar (unseasoned)
- 1 tablespoon sesame oil
- 1 teaspoon fish sauce (optional, but great umami)
- 1/2 teaspoon crushed red pepper flakes (or to taste)
- 1/2 teaspoon black pepper
- 1–2 teaspoons granular or liquid keto-friendly sweetener (like allulose, erythritol, or monk fruit), to balance the sauce
Optional thickener (keto-friendly): 1/2 teaspoon xanthan gum, lightly sprinkled, if you prefer a thicker sauce.

Keeping It Fresh
- Batch prep smart: Slice the chicken and chop vegetables up to 24 hours ahead. Keep them in separate containers so the veggies don’t get soggy.
- Sauce on standby: The sauce keeps well for 5–7 days in the fridge. Make a double batch and shake before using.
- Store leftovers right: Cool quickly and refrigerate in an airtight container for up to 3 days.
Reheat in a skillet over medium heat for best texture.
- Freeze with care: Cooked zucchini and mushrooms can soften after freezing. If you plan to freeze, undercook the veggies slightly. Freeze up to 2 months.
Why This is Good for You
- Low in carbs, high in protein: Lean chicken supports muscle and satiety without spiking carbs.
- Fiber and micronutrients: Broccoli, peppers, and zucchini add fiber, vitamin C, potassium, and antioxidants that support overall health.
- Healthy fats: Avocado oil and sesame oil contribute heart-friendly fats that help you feel satisfied.
- Balanced flavor without sugar: A small amount of keto-friendly sweetener balances the savory sauce, so you get takeout-level flavor without hidden sugars.
What Not to Do
- Don’t overcrowd the pan. Too much food at once steams instead of sears.
Cook in batches if needed.
- Don’t overcook the chicken. Thin slices cook fast. Pull them when just done to avoid dryness.
- Don’t skip the aromatics. Garlic and ginger are your flavor foundation. They make a simple sauce taste complex.
- Don’t pour in xanthan gum all at once. A little goes a long way.
Sprinkle lightly and toss well to avoid clumps.
- Don’t rely on seasoned rice vinegar. It often contains sugar. Use unseasoned to keep it keto.
Variations You Can Try
- Spicy sesame chicken: Add 1–2 teaspoons chili-garlic sauce or a drizzle of sriracha to the sauce. Top with extra sesame seeds.
- Lemon-ginger twist: Swap rice vinegar for fresh lemon juice and add extra ginger.
Finish with lemon zest.
- Cashew crunch: For those who include nuts, toss in a small handful of toasted cashews at the end. Keep portions modest to stay keto-friendly.
- Bok choy and snow peas: Sub in sliced baby bok choy and a small amount of snow peas for a different crunch. Monitor carbs if you’re strict.
- Coconut-lime: Stir in 2–3 tablespoons coconut cream and a squeeze of lime at the end for a silky, tropical note.
- Beef or shrimp swap: Use thinly sliced flank steak or peeled shrimp instead of chicken.
Adjust cook time: steak sears fast; shrimp need just 2–3 minutes.
FAQ
Can I use frozen vegetables?
Yes, but expect a bit more moisture. Thaw and pat dry first, or cook them straight from frozen in a hot pan and let the water evaporate before adding the sauce.
Is coconut aminos the same as soy sauce?
No. Coconut aminos are less salty and slightly sweeter.
If you use tamari or soy sauce, start with a little less and adjust to taste.
How do I make it spicier without changing the flavor too much?
Add more red pepper flakes, a dash of chili oil, or a small spoon of sambal oelek. These boost heat without overpowering the sauce.
What can I serve this with on keto?
Cauliflower rice is the go-to. You can also use zucchini noodles or shredded cabbage sautéed in a little oil and salt.
Do I have to use xanthan gum?
No.
The stir fry tastes great without it. Xanthan gum just gives the sauce a restaurant-style gloss and cling.
Can I make this ahead for meal prep?
Absolutely. Cook as directed, cool quickly, and portion into containers with cauliflower rice.
Reheat in a skillet or microwave until hot.
How do I keep the chicken tender?
Slice it thin, cook over medium-high heat, and don’t walk away. Pull it as soon as it’s opaque and lightly browned. You can also marinate it in a tablespoon of the sauce for 15 minutes before cooking.
