How to Make Keto Chicken Stir Fry with Broccoli and Bell Peppers Recipe
Step 1: Brown the Chicken
Start by heating the olive oil in a large skillet over medium high heat. Add the chicken thighs cut into bite-sized pieces and cook them undisturbed for about 6 to 8 minutes. You want that beautiful golden crust to seal in the juices and flavor. Once browned and cooked through, remove them from the pan and set aside to keep warm.
Step 2: Sauté the Aromatics
In the same skillet, pour in the sesame oil. Then toss in the minced garlic and freshly grated ginger. Stir and cook them briefly—just 30 seconds or until their aroma fills the kitchen. This step is crucial to building the flavor base for your sauce, so don’t rush it!
Step 3: Prepare the Sauce
Next, add the soy sauce, sugar free ketchup, rice vinegar, sweetener, and red pepper flakes. Stir everything together and allow it to come to a gentle simmer. If you want a thicker sauce, whisk together the xanthan gum with water and incorporate it slowly to avoid clumps. Let the sauce cook for 2 to 3 minutes until it slightly thickens into a beautiful glaze.
Step 4: Toss in the Veggies
Add the broccoli florets and sliced bell peppers directly to the sauce. Stir everything frequently and cook for 3 to 4 minutes until the vegetables maintain a tender crispness—just soft enough to be enjoyable but still packed with that fresh bite.
Step 5: Combine Chicken and Sauce
Return the cooked chicken pieces to the skillet. Toss thoroughly to make sure every juicy morsel is coated in the flavorful sauce. Let everything heat through another 2 minutes so the flavors marry perfectly and the dish is piping hot all the way through.

Side Dishes
For a complete keto-friendly meal, serving this stir fry over fluffy cauliflower rice is an unbeatable choice. It soaks up all those incredible sauce flavors without any extra carbs. You can also consider a simple side of steamed spinach or sautéed garlic green beans for extra veggie power.

Reheating
Reheat leftovers gently in a skillet over medium heat or in the microwave until warmed through. Adding a splash of water or broth can help revive the sauce and keep the veggies tender but not soggy.
