Ingredients
- Boneless skinless chicken breasts: About two large pieces Tender white meat soaks up the sauce and bakes up juicy Choose chicken with no pink spots and a fresh scent
- Low sodium soy sauce: Brings savory depth without overpowering saltiness Look for one labeled low sodium to keep the sauce balanced
- Light brown sugar: Gives the sauce rich sweetness and balances the soy Opt for soft brown sugar with no clumps for easier mixing
- Seasoned rice wine vinegar: Brightens up the flavors with a gentle tang Make sure to get seasoned vinegar as it is sweeter and milder
- Fresh garlic Grated: Adds bold flavor Fresh garlic will give the most aroma and zest
- Fresh ginger Grated: Lifts the dish with a warm kick Pick roots that are firm and unwrinkled for best flavor
- Sesame oil: Gives an unmistakable nutty aroma Use toasted sesame oil for a deeper flavor
- Cornstarch: Thickens the sauce so it coats everything smoothly Always check for a fine powder with no lumps
- Frozen stir fry vegetables Any blend: Steamed before adding for perfect texture Choose bright colored veggies for freshness
- Cooked white rice Jasmine is classic: Offers the perfect fluffy base Fresh cooked rice soaks up the sauce best

Sesame oil is my favorite part as it adds that signature takeout aroma I always crave My son loves helping shred the chicken and it’s become a fun messy job we do together whenever we make this casserole
Storage Tips
Store any leftovers in an airtight container in the fridge They keep well for up to three days and the flavors get even better Overnight I like to reheat portions in the microwave with a splash of water so the rice stays fluffy This casserole also freezes well portioned into single serve containers for future lunches
Ingredient Substitutions
If you do not have chicken breasts try using boneless thighs for added richness You can swap in quinoa or brown rice for Jasmine if you want more whole grains For veggies, any frozen stir fry mix works or use up whatever fresh chopped veggies are in your drawer Broccoli and bell peppers are especially good If you need to keep it gluten free opt for tamari instead of soy sauce

This casserole is a hit all on its own but I love to serve it with extra steamed broccoli or a simple cucumber salad to add crunch For a finishing touch a sprinkle of sliced green onions or sesame seeds looks and tastes great Sometimes we use leftovers wrapped up in a tortilla for a grab and go lunch
