Easy Keto Chicken Stir Fry Meal Prep - Simple, Flavorful, and Ready for the Week
Ingredients
Method
- Prep the chicken. Pat chicken dry and slice into thin, bite-size strips. Season lightly with salt and pepper. Thinner strips cook faster and stay more tender.
- Chop the veggies. Cut broccoli into small florets. Slice bell pepper and zucchini into thin strips. Slice mushrooms and red onion. Mince garlic and grate ginger.
- Make the sauce. In a small bowl, whisk tamari (or coconut aminos), rice vinegar, sesame oil, minced garlic, and ginger. Add red pepper flakes if you like heat. If using xanthan gum, sprinkle it in and whisk well to avoid clumps.
- Heat the pan. Add 1 tablespoon oil to a large skillet or wok over medium-high heat. When it shimmers, it’s ready.
- Cook the chicken in batches. Add half the chicken and cook 3–4 minutes, stirring occasionally, until lightly browned and just cooked through. Remove to a plate. Repeat with remaining chicken, adding more oil as needed.
- Stir-fry the veggies. Add another drizzle of oil if the pan looks dry. Toss in broccoli and snap peas first. Cook 2 minutes. Add bell pepper, zucchini, mushrooms, and red onion. Stir-fry 3–4 minutes until crisp-tender.
- Combine and sauce. Return chicken and any juices to the pan. Pour in the sauce. Toss everything to coat. Simmer 1–2 minutes to thicken slightly. Taste and adjust salt, vinegar, or heat.
- Finish and garnish. Remove from heat. Sprinkle with sesame seeds and sliced green onions. A squeeze of lime brightens everything up.
- Portion for meal prep. Divide evenly into 4 containers. Let cool uncovered for 10–15 minutes before sealing to prevent condensation.
Why This Recipe Works
This recipe leans on simple, everyday ingredients that deliver big flavor with minimal fuss. You’ll use quick-cooking chicken breast and low-carb vegetables that stay crisp-tender even after reheating.
The sauce uses tamari or coconut aminos, a touch of rice vinegar, and sesame oil for depth—no sugary glaze needed. It comes together in one pan, so cleanup is painless. And best of all, it reheats beautifully for lunches or dinners throughout the week.

How to Make It
- Prep the chicken. Pat chicken dry and slice into thin, bite-size strips.
Season lightly with salt and pepper. Thinner strips cook faster and stay more tender.
- Chop the veggies. Cut broccoli into small florets. Slice bell pepper and zucchini into thin strips.
Slice mushrooms and red onion. Mince garlic and grate ginger.
- Make the sauce. In a small bowl, whisk tamari (or coconut aminos), rice vinegar, sesame oil, minced garlic, and ginger. Add red pepper flakes if you like heat.
If using xanthan gum, sprinkle it in and whisk well to avoid clumps.
- Heat the pan. Add 1 tablespoon oil to a large skillet or wok over medium-high heat. When it shimmers, it’s ready.
- Cook the chicken in batches. Add half the chicken and cook 3–4 minutes, stirring occasionally, until lightly browned and just cooked through. Remove to a plate.
Repeat with remaining chicken, adding more oil as needed.
- Stir-fry the veggies. Add another drizzle of oil if the pan looks dry. Toss in broccoli and snap peas first. Cook 2 minutes.
Add bell pepper, zucchini, mushrooms, and red onion. Stir-fry 3–4 minutes until crisp-tender.

- Finish and garnish. Remove from heat.
Sprinkle with sesame seeds and sliced green onions. A squeeze of lime brightens everything up.
- Portion for meal prep. Divide evenly into 4 containers. Let cool uncovered for 10–15 minutes before sealing to prevent condensation.
How to Store
- Refrigerator: Store in airtight containers for up to 4 days.
- Freezer: Freeze up to 2 months.
For best texture, slightly undercook the veggies if you plan to freeze.
- Reheating: Microwave 1–2 minutes, stirring halfway, or warm in a skillet over medium heat with a splash of water to loosen the sauce.
- Meal prep tip: If you like extra crunch, pack a portion of raw sliced green onion or sesame seeds separately and add after reheating.
Benefits of This Recipe
- Keto-friendly and low-carb: Veggie choices and a no-sugar sauce keep carbs in check while delivering fiber and micronutrients.
- High protein: Chicken breast provides steady energy and supports satiety.
- Fast and flexible: It’s ready in about 30 minutes and adapts to what you have on hand.
- Budget-conscious: Uses everyday ingredients and stretches across four meals.
- Great texture after reheating: Crisp-tender veggies and juicy chicken hold up throughout the week.
What Not to Do
- Don’t overcrowd the pan. Crowding steams the chicken and veggies. Cook in batches for better browning and texture.
- Don’t skip drying the chicken. Moisture prevents searing and encourages sticking.
- Don’t overcook the vegetables. Soft veggies turn mushy when reheated. Aim for crisp-tender.
- Don’t rely on cornstarch or sugary sauces. They add carbs quickly.
Stick with tamari, vinegar, aromatics, and a touch of xanthan gum if desired.
- Don’t sauce too early. Add the sauce at the end so it coats instead of burning.
Recipe Variations
- Chicken thigh swap: Use boneless, skinless thighs for extra juiciness. Cook 1–2 minutes longer.
- Spicy garlic version: Double the garlic, add chili crisp (no added sugar) or extra red pepper flakes.
- Lemon-ginger twist: Swap lime for lemon and bump ginger to 2 tablespoons for a zingy, fresh profile.
- Veggie rotation: Try asparagus, cabbage, bok choy, or green beans. Keep starchy veggies (like carrots or corn) to a minimum for keto.
- Saucy sesame: Add 1 tablespoon tahini to the sauce for a richer, nuttier finish.
- Extra protein: Toss in scrambled eggs at the end, or add sliced chicken sausage (no added sugar).
- Keto “rice” base: Serve over cauliflower rice sautéed in garlic and a little butter.
Keep portions moderate to avoid watering down the sauce.
FAQ
How many carbs are in this stir fry?
Exact numbers vary based on your vegetables and sauce brand, but expect roughly 6–9 net carbs per serving without cauliflower rice. Use coconut aminos for a slightly sweeter flavor but note it can add a bit more carbs than tamari.
Can I make this without xanthan gum?
Yes. Simply simmer the sauce for an extra minute to reduce, or whisk 1 teaspoon of sesame paste or almond butter into the sauce for subtle thickening and richness.
How do I keep the chicken tender?
Slice thinly, cook over medium-high heat, and avoid overcooking.
Pull it as soon as it’s no longer pink. Letting the chicken rest briefly on a plate while you cook the veggies helps keep juices in.
What can I substitute for tamari?
Use coconut aminos if you avoid soy. It’s slightly sweeter and less salty, so taste and add a pinch of salt if needed.
Liquid aminos also work but adjust to taste.
Can I make this vegetarian?
Yes. Swap chicken for extra-firm tofu or tempeh. For tofu, press it well, cube it, and pan-sear until golden before adding the veggies and sauce.
Will it still taste good on day four?
Absolutely.
The flavors deepen, and the veggies stay crisp if you avoid overcooking. Reheat gently and garnish with fresh green onions or a squeeze of lime to brighten it up.
What oil is best for high heat?
Avocado oil handles high heat well and has a neutral flavor. Light olive oil works too.
Add toasted sesame oil at the end for flavor, not for high-heat cooking.
