Ingredients

For the Best Keto Stir Fry, you’ll need:

• 1 lb (454g) protein of choice (chicken thighs, beef sirloin, or shrimp)
• 2 tbsp (30ml) avocado oil, divided
• 3 cloves garlic, minced (about 1 tbsp)
• 1 tbsp (15g) fresh ginger, grated
• 3 cups (about 300g) low-carb vegetables (broccoli florets, sliced bell peppers, zucchini, bok choy)
• 2 tbsp (30ml) coconut aminos (a keto-friendly soy sauce alternative)
• 1 tbsp (15ml) rice vinegar (unsweetened)
• 1 tsp (5g) toasted sesame oil
• 1 tsp (5g) crushed red pepper flakes (optional)
• 2 tbsp (30g) erythritol or monk fruit sweetener
• 1 tbsp (15ml) fish sauce (optional, for depth of flavor)
• 2 green onions, sliced for garnish
• 1 tbsp (15g) sesame seeds for garnish

The coconut aminos provide the savory umami flavor essential to the low carb stir fry sauce without the soy and gluten found in traditional soy sauce, making this recipe both keto and paleo-friendly.

Pro Tips

Select the Right Cooking Oil

For the Best Keto Stir Fry, choosing an oil with a high smoke point is crucial. Avocado oil is ideal because it remains stable at the high temperatures needed for proper stir-frying (up to 520°F/270°C). Unlike olive oil, which can break down and become bitter, avocado oil allows you to achieve that authentic wok hei—the slightly charred flavor that makes restaurant stir-fries so delicious.

Prep Everything Before Heating the Pan

The most common mistake in making a keto vegetable stir fry is not having ingredients prepped and ready. Stir-frying happens quickly, so slice all vegetables uniformly (this ensures even cooking), mix your sauce ingredients in advance, and have your protein cut and patted dry before heating your pan. This mise en place approach means you’ll never overcook components while fumbling with prep work.

Cook in Batches for Perfect Texture

To achieve restaurant-quality results, avoid overcrowding your pan. Cook your protein first until just done, then remove it and set aside while cooking vegetables. Overcrowding causes steaming instead of stir-frying, resulting in soggy vegetables and rubbery meat. For the Best Keto Stir Fry, it’s better to work in batches and maintain that high heat that creates caramelization and textural contrast.

Instructions

Step 1: Prepare Your Protein

Slice your chosen protein into thin, bite-sized pieces, going against the grain if using beef or chicken. Season with salt and pepper, then pat dry with paper towels to remove excess moisture. This crucial step ensures your meat will sear rather than steam, creating those delicious caramelized edges that define a great keto chicken stir fry.

Step 2: Mix Your Sauce

In a small bowl, combine coconut aminos, rice vinegar, sesame oil, erythritol or monk fruit sweetener, and fish sauce (if using). Whisk until the sweetener dissolves completely. This balanced sauce delivers the sweet-savory-tangy profile of traditional stir-fry sauces without the carbs, making it perfect for your Best Keto Stir Fry.

Step 3: Sear Your Protein

Heat 1 tablespoon of avocado oil in a large wok or heavy skillet over high heat until it’s shimmering but not smoking. Add your protein in a single layer (working in batches if necessary) and let it sear undisturbed for 1-2 minutes before stirring. Continue cooking until just done—about 3-4 minutes total for chicken or beef, 2 minutes for shrimp. Remove from the pan and set aside.

Step 4: Stir-Fry the Aromatics and Vegetables

Add the remaining tablespoon of oil to the hot pan. Quickly add minced garlic and grated ginger, stirring constantly for 30 seconds until fragrant but not burnt. Add your firmer vegetables first (like broccoli or bell peppers), stirring frequently for about 2 minutes. Add more delicate vegetables (like bok choy or zucchini) and continue stir-frying for another 2-3 minutes until vegetables are bright and crisp-tender.

Step 5: Combine and Finish

Return the cooked protein to the pan with the vegetables. Pour your prepared sauce over everything and toss to coat, allowing the sauce to bubble and slightly reduce for 1-2 minutes. The sauce will cling to the ingredients without needing cornstarch, keeping your Best Keto Stir Fry low in carbs while delivering maximum flavor. Garnish with sliced green onions and sesame seeds before serving immediately.

Variations

Sesame Ginger Salmon Stir Fry

For a luxurious omega-3 boost, substitute cubed salmon for the protein in your Best Keto Stir Fry. Cook the salmon for just 2-3 minutes total to maintain its tender texture. Increase the ginger to 2 tablespoons and add 2 extra tablespoons of sesame seeds. This variation pairs particularly well with bok choy, asparagus, and mushrooms for an elegant dinner option that’s still quick to prepare.

Spicy Thai-Inspired Stir Fry

Transform your keto stir fry recipe with Thai flavors by adding 1-2 tablespoons of red curry paste to your sauce mixture. Include 1/4 cup of full-fat coconut milk for creaminess and 1/4 cup of chopped Thai basil added at the last minute. This variation works beautifully with chicken or shrimp and pairs well with red bell peppers, zucchini, and snow peas for a vibrant low-carb meal with complex flavor notes.

Vegetarian Keto Stir Fry

Create a satisfying plant-based version by substituting the animal protein with extra-firm tofu (pressed and cubed) or tempeh. For additional protein, add 1/2 cup of chopped walnuts or 1/4 cup of hemp seeds. Increase the variety of vegetables to include cauliflower florets, sliced mushrooms, and spinach for a nutrient-dense vegetable keto stir fry that’s substantiating enough to serve as a main dish.

Storage/Serving

Store leftover Best Keto Stir Fry in an airtight container in the refrigerator for up to 3 days. The flavors often deepen overnight, making this an excellent meal prep option. Reheat gently in a skillet over medium heat for 3-4 minutes, adding a splash of water if needed to loosen the sauce. Avoid microwave reheating if possible, as it can make the vegetables soggy and overcooked.

For serving, present your Best Keto Stir Fry over cauliflower rice for a traditional presentation that adds volume without significant carbs. Alternatively, serve in lettuce cups for a refreshing hand-held option perfect for casual dining. For a more substantial meal, pair with shirataki noodles tossed in a little sesame oil and coconut aminos, creating a keto-friendly version of classic lo mein that complements the bold flavors of your stir fry.

FAQs

Can I make the Best Keto Stir Fry ahead of time?
Yes, you can prepare components ahead of time. Slice proteins and vegetables and refrigerate separately for up to 24 hours. Mix the sauce and store it separately. When ready to eat, stir-fry quickly for the freshest flavor and optimal texture.

What’s the best pan to use for a keto stir fry?
A carbon steel wok is ideal because it heats quickly and distributes heat evenly. However, any large, heavy-bottomed skillet works well—cast iron is an excellent alternative that maintains high heat consistently.

How can I thicken my keto stir fry sauce without cornstarch?
Allow your sauce to reduce slightly by simmering it longer. For additional thickening, whisk in 1/4 teaspoon of xanthan gum or 1 tablespoon of unflavored gelatin powder (bloomed first in cold water).

Which vegetables are lowest in carbs for my stir fry?
Opt for above-ground vegetables like broccoli, zucchini, bell peppers, spinach, cabbage, and bok choy. These typically contain 2-5g net carbs per cup, compared to carrots or onions which have higher carb counts.

Can I use frozen vegetables in my keto stir fry?
Yes, but thaw and drain them well first to remove excess moisture. Frozen vegetables work best when added directly to the hot pan without pre-cooking, as they’re partially cooked during processing.
