I tested this version so many times that my skillet practically knows the recipe by heart.
Why You Should Try This Keto Stir Fry Recipe
This keto stir fry recipe tastes savory, slightly spicy, and a little sweet without kicking you out of ketosis. You get crisp-tender vegetables, juicy bites of meat, and a sauce that clings to every piece instead of pooling at the bottom of the pan.

Ingredients You’ll Need
Protein options
Pick one or mix two. Aim for about 1 pound total.
- 1 lb boneless skinless chicken thighs, thinly sliced
- Thighs stay juicy and forgiving if you cook them a bit longer.
- or 1 lb flank steak or sirloin, sliced very thin against the grain
- Freeze the steak for 20 minutes so it slices easily.
- or 1 lb peeled shrimp, tail on or off
- Pat shrimp very dry so they sear instead of steam.
- or 1 lb extra-firm tofu, pressed and cubed
- Use extra-firm only, and pat it dry to help it crisp in the pan.
Low carb vegetables
Use about 4 to 5 cups total chopped veggies.
- 1 cup broccoli florets
- 1 cup sliced bell pepper (red, yellow, or orange)
- 1 cup sliced zucchini or yellow squash
- 1 cup sliced mushrooms (cremini or white button)
- 1/2 cup thinly sliced green onion, white and green parts separated
- 1 cup shredded green cabbage or bagged coleslaw mix
- Bagged coleslaw mix saves time and works great in stir fry.
Aromatics
- 3 cloves garlic, minced
- 1 tablespoon fresh ginger, minced or grated
- Use the frozen ginger cubes if you keep them in your freezer; they taste great and save time.
Keto stir fry sauce
Whisk these in a small bowl:
- 1/3 cup soy sauce or tamari (use tamari or coconut aminos for gluten free)
- 2 tablespoons avocado oil or light olive oil
- 1 tablespoon rice vinegar (unseasoned, no added sugar)
- 1 to 2 tablespoons sugar free brown sweetener
- I like Swerve Brown or Lakanto Golden for a caramel note.
- 1 teaspoon toasted sesame oil
- 1 teaspoon hot sauce or sriracha (check label for sugar)
- 1/4 teaspoon xanthan gum
- This thickens the sauce without cornstarch; sprinkle it in slowly while whisking.
Optional add ins and toppings
- 1/4 cup roasted peanuts or cashews, roughly chopped
- Use sparingly if you track carbs tightly.
- 1 tablespoon sesame seeds
- Extra sliced green onion
- Red pepper flakes for more heat
- 1 bag frozen riced cauliflower, heated
- This works as the low carb “rice” base.
Oil and seasoning
- 2 to 3 tablespoons avocado oil or high heat oil
- 1/2 teaspoon black pepper
- Salt to taste
- Extra soy sauce or tamari at the table
Equipment
- Large nonstick skillet or wok
- Cutting board and sharp knife
- Small bowl and whisk for the sauce
- Tongs or spatula
- Paper towels to pat protein dry
Tips & Tricks
- Slice protein very thin so it cooks fast and stays tender.
- Pat meat or tofu dry with paper towels to help it brown instead of steam.
- Pre chop all veggies and mix the sauce before you turn on the stove.
- Heat the pan until it almost smokes so the stir fry gets that restaurant-style sizzle.
- Cook protein in batches so the pan never feels crowded.
- Stir the sauce again right before you pour it in because xanthan gum can clump.
- Add softer veggies like zucchini and cabbage near the end so they stay crisp-tender.
- Taste the sauce at the end and adjust with more soy sauce, sweetener, or hot sauce.
- Serve over hot cauliflower rice to soak up every drop of sauce.
- Use leftovers as a filling for lettuce wraps the next day.
How to Make Keto Stir Fry Recipe
Step 1: Prep protein and vegetables
Slice your chosen protein into thin strips or bite-size pieces and pat everything very dry. Season lightly with salt and pepper. Chop all vegetables into similar-size pieces so they cook evenly, then set them in separate piles or bowls.
Mince the garlic and ginger and keep them together. Whisk all sauce ingredients in a small bowl, sprinkle the xanthan gum in while you whisk, and set the bowl near the stove. Heat your cauliflower rice if you plan to serve the stir fry over it.
Step 2: Sear the protein
Place a large skillet or wok over medium-high heat and let it heat until a drop of water sizzles. Add 1 to 1 1/2 tablespoons oil and swirl to coat the pan. Add half the protein in a single layer and let it sear without moving it for 1 to 2 minutes.
Stir and cook until the protein cooks through and browns on the edges. Transfer it to a plate and repeat with the remaining protein, adding more oil if the pan looks dry. Keep the cooked protein nearby.
Step 3: Stir fry the vegetables
Add another drizzle of oil to the hot pan. Toss in the broccoli and bell peppers and cook 2 to 3 minutes, stirring often, until they start to soften but still feel crisp. Add mushrooms and the white parts of the green onion and cook another 2 minutes.
Add zucchini and cabbage and cook 1 to 2 minutes more. Toss in the garlic and ginger and stir constantly for about 30 seconds so they turn fragrant but do not burn. Keep the heat fairly high so the veggies stay bright and crisp.
Step 4: Add sauce and finish
Return the cooked protein and any juices to the pan with the vegetables. Give the sauce a quick whisk, then pour it over everything. Toss well so the sauce coats every piece.
Let the stir fry bubble for 1 to 2 minutes so the sauce thickens and turns glossy. Taste and adjust seasoning with more soy sauce, sweetener, or hot sauce. Sprinkle in the green parts of the green onion, sesame seeds, and nuts if you use them, then turn off the heat.
Step 5: Serve
Spoon hot cauliflower rice into bowls. Top with a generous scoop of keto stir fry. Add extra green onion, sesame seeds, and a pinch of red pepper flakes if you like heat.
Serve right away while the veggies still feel crisp and the sauce tastes hot and fragrant. Watch everyone act surprised that a low carb stir fry tastes this satisfying.
What to Serve with Keto Stir Fry Recipe
This Keto Stir Fry Recipe pairs perfectly with cauliflower rice, shredded cabbage, or simple sautéed spinach. You can add a side of cucumber salad with rice vinegar and sesame seeds for a cool, crunchy contrast. A bowl of miso-style broth or clear vegetable soup rounds out the meal without many extra carbs.
If you pack lunches, portion the stir fry into containers with cauliflower rice and a side of sliced avocado. Kids often enjoy it with plain steamed broccoli or carrot sticks on the side.
