Step 1: Prepare the Rice
Cook the rice according to the package directions while preparing the chicken.
Once cooked, fluff the rice gently with a fork and keep it warm until you're ready to assemble the bowls.
Step 2: Season and Cook the Chicken
Pat the chicken pieces dry with paper towels.
Season evenly with salt and black pepper.
Heat the olive oil or avocado oil in a large skillet over medium-high heat.
Add the chicken in a single layer and cook for 5–7 minutes, stirring occasionally, until golden around the edges and fully cooked.
The chicken should reach an internal temperature of 165°F (74°C).
Transfer the cooked chicken to a plate and set aside.
Step 3: Make the Pineapple Sauce
Reduce the skillet heat to medium.
Add the pineapple juice, low-sodium soy sauce, brown sugar, vinegar, minced garlic, and ginger.
Stir everything together until well combined.
Bring the mixture to a gentle simmer and cook for approximately 2 minutes, allowing the sugar to dissolve and the garlic to release its aroma.
Step 4: Thicken the Sauce
In a small bowl, whisk the cornstarch with 2 tablespoons of cold water until completely smooth.
Slowly pour the mixture into the simmering pineapple sauce while stirring.
Continue cooking for 1–2 minutes until the sauce becomes thick, smooth, and glossy.
It should lightly coat the back of a spoon.
Step 5: Combine the Chicken and Vegetables
Return the cooked chicken to the skillet.
Add the pineapple chunks and sliced red bell pepper.
Toss everything gently until the chicken, pineapple, and vegetables are evenly coated in the sauce.
Cook for another 2–3 minutes, allowing the pineapple to warm through and the bell pepper to soften slightly while maintaining a little crunch.
Taste the sauce and adjust the seasoning if needed.
Step 6: Assemble the Rice Bowls
Divide the warm rice evenly among four serving bowls.
Spoon the glazed chicken, pineapple chunks, and bell peppers over the rice.
Drizzle any remaining sauce from the skillet over each serving.
Finish with sliced green onions and optional sesame seeds.
Serve your Hawaiian Chicken Rice Bowls immediately while the chicken is warm and the pineapple glaze is beautifully glossy.
