Step‑by‑Step Instructions for Pot Sweet & Sour Chicken
Step 1: Sear Chicken
Start by setting your Instant Pot to ‘sauté’ mode and allow it to heat up for a minute. Once hot, pour in the sesame oil, then add the diced chicken. Sear for about 1 minute on each side until it’s lightly browned. This initial step seals in the juices, providing a flavorful base for your Pot Sweet & Sour Chicken.
Step 2: Add Vegetables
After the chicken is evenly seared, turn off the sauté function. Layer the chopped red onion, vibrant red pepper, and pineapple chunks over the chicken without stirring. This creates a beautiful colorful layer that will steam perfectly during cooking, allowing the sweet and tangy flavors to meld into the chicken.
Step 3: Prepare Sauce
In a mixing bowl, combine the rice vinegar, Whole30 approved ketchup, pineapple juice, coconut aminos, minced garlic, and Chinese 5 Spice. Whisk the ingredients until thoroughly blended. Pour this aromatic sauce over the chicken and vegetables in the Instant Pot, ensuring an even coat, then securely set the lid to ‘sealed’ and cook on ‘manual high pressure’ for 5 minutes.
Step 4: Release Pressure
Once the cooking time is completed, perform a quick pressure release by turning the valve to venting. Carefully remove the lid, allowing the steam to escape. Using a slotted spoon, remove the chicken and vegetables and place them in a serving bowl, leaving the flavorful sauce behind in the Instant Pot.
Step 5: Thicken Sauce
Reset the Instant Pot to ‘sauté’ mode to thicken the sauce. In a small bowl, mix the arrowroot flour with 1/3 cup of cold water until dissolved. Gradually pour this mixture into the remaining liquid in the Instant Pot, stirring continuously for about 2 minutes until the sauce thickens to a glossy consistency that will perfectly coat your Pot Sweet & Sour Chicken.
Step 6: Combine & Serve
Pour the thickened sauce over the chicken and vegetables, giving it a gentle toss to ensure everything is well coated. For an added touch, garnish with sesame seeds and sliced green onions. Serve your juicy Pot Sweet & Sour Chicken warm, ideally over a bed of cauliflower rice for a nourishing and delightful meal!

Make Ahead Options
These Whole30 Instant Pot Sweet and Sour Chicken are perfect for meal prep, saving you valuable time during busy weeknights! You can chop the vegetables and marinate the chicken with the sauce ingredients up to 24 hours in advance. Simply store the prepped components in airtight containers in the refrigerator to keep them fresh. When you’re ready to cook, pour everything into the Instant Pot, and proceed with the usual cooking steps. For best quality, make sure to refrigerate the chicken and veggies separately until you’re ready to cook, ensuring they remain crisp and flavorful. This allows you to enjoy delicious, home-cooked Whole30 Instant Pot Sweet and Sour Chicken with minimal effort!
