• 1 tablespoon sesame oil
• 2 cloves garlic, minced
• 1 teaspoon fresh grated ginger

Tips for the Best Teriyaki Chicken Casserole

Use rotisserie chicken to make prep even easier. If you like your vegetables a little softer, you can steam the broccoli for a minute or two before mixing it in. Jasmine rice works especially well here because it stays tender and soaks up all that delicious sauce. For extra flavor, add a few more green onions or a light sprinkle of sesame seeds right before serving.

Variations and Substitutions

This casserole is easy to adjust with what you have on hand. Swap the broccoli for snap peas or zucchini, use brown rice for a heartier texture, or add mushrooms for even more flavor. You can also use cooked turkey instead of chicken if that is what you have in the fridge. If your family likes a little heat, a pinch of red pepper flakes or a drizzle of sriracha is really good on top.

How to Store and Reheat

Store leftovers in an airtight container in the refrigerator for up to 4 days. Reheat individual portions in the microwave until warmed through, or cover the casserole dish and reheat in the oven at 350°F until hot. If it seems a little dry after chilling, add a small splash of water before reheating.
