About the Ingredients

1 lb (450g) boneless, skinless chicken breast, sliced thin

Chicken breast is lean and cooks fast. Substitute with shrimp, beef, or tofu for variety.

2 tbsp (30ml) avocado oil, divided

Avocado oil has a high smoke point, perfect for stir-frying. Use any neutral oil like canola or grapeseed.

1 medium head broccoli, cut into small florets (about 3 cups)

Broccoli adds crunch and fiber. Swap with cauliflower or green beans.

1 red bell pepper, sliced thin

Red bell pepper is sweet and colorful. Use any color you like.

1 cup (150g) sugar snap peas

Snap peas are crisp and sweet. Substitute with snow peas or sliced zucchini.

3 cloves garlic, minced

Fresh garlic is best, but use 1 tsp pre-minced if in a pinch.

1 tbsp (15ml) fresh ginger, grated

Ginger adds warmth. Use 1 tsp ground ginger if fresh isn't available.

1/4 cup (60ml) low-sodium soy sauce (or tamari for gluten-free)

Soy sauce is the base of the sauce. Use coconut aminos for a soy-free option.

2 tbsp (30ml) rice vinegar

Rice vinegar adds tang. Apple cider vinegar works too.

1 tbsp (15ml) toasted sesame oil

Sesame oil adds nutty flavor. Use a little goes a long way.

1 tbsp (8g) erythritol or other low-carb sweetener

Sweetener balances the acidity. Use stevia or monk fruit, but adjust to taste.

1 tsp xanthan gum (optional, for thickening)

Xanthan gum thickens the sauce without carbs. Cornstarch can be used if not strict low-carb.

2 green onions, sliced (for garnish)

Green onions add freshness. Skip if you don't have them.

1 tbsp sesame seeds (optional, for garnish)

Sesame seeds add crunch. Toasted sesame seeds are even better.

Tips & Tricks

  • Prep all ingredients before you start cooking – stir-frying goes fast.
  • Slice chicken against the grain for tender pieces.
  • Don't overcrowd the pan; cook in batches if needed to get a good sear.
  • Taste the sauce before adding, adjust sweetener or soy sauce to your liking.

Pro Tips

1

Use a wok or large skillet for even heat distribution.
2

Cut vegetables into uniform sizes for even cooking.
3

Add the sauce at the end to prevent the vegetables from getting soggy.
4

If using xanthan gum, whisk it into the sauce before adding to avoid lumps.

Step-by-Step Instructions

1. Prep Ingredients

Slice chicken into thin strips, chop broccoli, slice bell pepper, and mince garlic and ginger. Have all ingredients within reach.

2. Make the Sauce

In a small bowl, whisk together soy sauce, rice vinegar, sesame oil, erythritol, and xanthan gum (if using). Set aside.

3. Cook the Chicken

Heat 1 tbsp avocado oil in a large wok or skillet over high heat (400°F/200°C). Add chicken in a single layer and cook without stirring for 2-3 minutes until browned. Then stir-fry for 2-3 more minutes until cooked through (internal temperature reaches 165°F/74°C). Remove chicken from the pan and set aside.

4. Stir-Fry the Vegetables

Add remaining 1 tbsp oil to the same pan. Add broccoli, bell pepper, and snap peas. Stir-fry over high heat for 4-5 minutes until crisp-tender and slightly charred at the edges.

5. Add Aromatics

Push vegetables to the side, add garlic and ginger to the center. Cook for 30 seconds until fragrant, then mix with vegetables.

6. Combine and Sauce

Return chicken to the pan. Pour the sauce over everything and toss to coat. Cook for 1-2 minutes until the sauce thickens and coats the ingredients evenly.

7. Garnish and Serve

Remove from heat. Sprinkle with green onions and sesame seeds. Serve immediately.

Delicious Variations

Protein Swap

Use beef strips or shrimp instead of chicken; adjust cooking time accordingly.

Add Heat

Stir in 1-2 tsp sriracha or red pepper flakes for a spicy kick.

Nutty Crunch

Top with chopped peanuts or cashews for extra texture.

How to Store Stir Fry Low Carb

Refrigerator

Store in an airtight container for up to 3 days.

Freezer

Freeze in a single layer on a baking sheet, then transfer to a freezer bag for up to 2 months.

Reheating

Reheat in a hot skillet over medium-high heat for 2-3 minutes, or microwave in 30-second bursts until hot.
