Why This Keto Stir Fry Stands Out
Not all stir fries are created equal. Many restaurant versions drown veggies and protein in sugary sauces, packing more carbs than an entire day’s keto allowance. This version keeps it simple, fresh, and macro-friendly while delivering maximum flavor.
Here’s why you’ll love it:
✅ Under 5g net carbs per serving – Stays firmly in keto territory.
✅ Customizable proteins & veggies – Use what you have on hand.
✅ No weird ingredients – Just real food with bold taste.
✅ Faster than takeout – Ready before the delivery driver would even arrive.
Key Ingredients for a Perfect Low-Carb Stir Fry
The secret to a great keto stir fry? Quality ingredients and a well-balanced sauce. Here’s what you’ll need:
Protein (Pick Your Favorite)
- Chicken (thigh or breast) – Juicy and quick-cooking.
- Beef (sirloin or flank steak) – Thinly sliced for tenderness.
- Shrimp – Cooks in minutes for a light option.
- Tofu (extra firm) – A great plant-based alternative.
Low-Carb Veggies (Mix & Match)
- Bell peppers (colorful and crunchy)
- Broccoli florets (for texture)
- Zucchini (lightly sautéed)
- Mushrooms (earthy flavor)
- Spinach or bok choy (wilts beautifully)

The Magic: Sugar-Free Stir Fry Sauce
Traditional stir fry sauces rely on sugar and cornstarch. This keto version keeps it rich and flavorful without the carbs:
- 2 tbsp soy sauce (or coconut aminos) – Salty umami base.
- 1 tbsp sesame oil – Adds depth.
- 1 clove garlic (minced) + 1 tsp ginger (grated) – Essential aromatics.
- 1 tsp rice vinegar – Brightens the flavor.
- ½ tsp chili paste (optional) – For a spicy kick.
(Pro tip: Double the sauce if you love extra flavor!)
Step-by-Step: How to Make Keto Stir Fry
1. Prep Your Ingredients
- Slice protein into thin, even strips for quick cooking.
- Chop veggies into bite-sized pieces (uniform size ensures even cooking).
- Mix sauce ingredients in a small bowl.
2. Cook the Protein
- Heat 1 tbsp avocado oil in a wok or large skillet over high heat.
- Add chicken, beef, or shrimp in a single layer (don’t overcrowd!).
- Sear 2-3 minutes per side until browned. Remove and set aside.
3. Stir Fry the Veggies
- In the same pan, add a splash more oil if needed.
- Toss in harder veggies first (like broccoli and peppers).
- After 2 minutes, add softer veggies (zucchini, mushrooms).
- Stir in garlic and ginger for the last 30 seconds (prevents burning).
4. Bring It All Together
- Return protein to the pan.
- Pour sauce over everything and toss well.
- Cook 1-2 more minutes until everything is glossy and well-coated.
5. Serve & Enjoy!
- Garnish with sesame seeds or sliced green onions.
- Serve over cauliflower rice or enjoy as-is.
