Ingredients
Here’s what you’ll need to whip up this yummy casserole. Most of these are likely already hanging out in your pantry and fridge!
- 2 cups cooked chicken, shredded or cubed: This is your chance to use up that rotisserie chicken or leftover baked chicken. Easy peasy!
- 2 cups cooked rice: Any kind works! White, brown, jasmine, basmati – whatever leftover rice you have is perfect.
- 1 cup carrots, sliced: Adds a lovely sweetness and crunch.
- 1 cup bell peppers, chopped (any color): I love using a mix of colors like red and green for extra visual appeal and flavor.
- 1 cup broccoli florets, steamed: A little green power! Steaming them slightly beforehand ensures they get perfectly tender in the oven without getting mushy.
- 1 cup frozen peas, thawed: Just run them under warm water or let them sit out for a few minutes. They add a pop of sweetness.
- 1/2 cup teriyaki sauce (store-bought or homemade): Use your favorite! The quality of your sauce will impact the final flavor, so choose one you love.
- 1 cup shredded mozzarella cheese: Because cheese makes everything better, right?
- 1/4 cup soy sauce: For that extra layer of salty, umami depth.
- 2 tablespoons olive oil: Just a little bit helps everything come together.
- 1 teaspoon garlic powder: Adds savory garlic flavor without the need for mincing.
- 1 teaspoon onion powder: Similar to garlic powder, an easy way to add onion flavor.
How to Make It
Alright, let’s get this casserole assembled! It comes together in just a few simple steps.
- First things first, you’ll want to get your oven ready. Preheat it to 350°F (175°C). While it heats up, grab a 9×13 inch baking dish and lightly grease it. You can use cooking spray or a little butter or oil. This just helps make sure nothing sticks!
- Now, grab your biggest mixing bowl. You’re going to add the main stars of the show: the cooked chicken, cooked rice, sliced carrots, chopped bell peppers, steamed broccoli, and thawed peas. Get all those goodies in there!
- Next, it’s time for the flavor bomb! Pour in the teriyaki sauce, soy sauce, add the garlic powder and onion powder. Now, give everything a really good stir. Make sure all those ingredients are evenly coated with the delicious sauce mixture. You want every bite to be packed with flavor!
- Once everything is beautifully coated, transfer the entire mixture from the bowl into your prepared baking dish. Spread it out evenly so you have a nice, flat layer.
- Now for the best part (in my opinion!): Sprinkle that glorious shredded mozzarella cheese all over the top. Get it right up to the edges!
- Cover the dish snugly with aluminum foil. Pop it into your preheated oven and bake for about 25-30 minutes. You’re looking for the vegetables to be tender and that cheese underneath to be all melty and bubbly.
- Carefully remove the foil. Now, bake it uncovered for another 5 minutes or so. This is when the cheese on top gets that lovely golden color and maybe a few crispy edges. Keep an eye on it!
- Once it’s golden and bubbly, take the casserole out of the oven. It will be hot! Let it cool for just a few minutes before you dive in. This helps it set slightly and prevents you from burning your tongue in your excitement (ask me how I know!).
Substitutions & Additions
This recipe is super flexible! Feel free to play around with the ingredients based on what you have or what you love.
- Protein: Not a chicken fan or don’t have any leftovers? You could easily swap the chicken for cooked shrimp, cubed tofu, or even leftover cooked pork or beef.
- Veggies: Use what’s in season or what your family likes! Corn, snap peas, mushrooms, water chestnuts, or even spinach (stirred in at the end) would be great additions.
- Rice: Quinoa or another grain could work in place of rice if you prefer.
- Sauce Boosters: Want more heat? Add a dash of sriracha or red pepper flakes to the sauce mixture. A teaspoon of grated fresh ginger would also add a lovely zing!
- Toppings: Before serving, sprinkle with sesame seeds, chopped green onions, or a drizzle of extra teriyaki sauce.
Tips for Success
Here are a few little pointers to make sure your Teriyaki Chicken Casserole turns out perfect every time!
- Use Cooked Ingredients: This casserole relies on already-cooked chicken and rice. Using leftovers is ideal, but make sure they are fully cooked beforehand.
- Don’t Overcook Veggies Initially: When steaming the broccoli (or other veggies), don’t make them mushy. You want them just tender-crisp because they’ll continue to cook in the oven.
- Mix Thoroughly: Take the time in step 3 to really coat everything evenly with the sauce. This ensures maximum flavor in every bite.
- Check for Tenderness: Before taking the foil off in step 7, poke a carrot or bell pepper with a fork to make sure the veggies are tender enough for your liking.
- Prep Ahead: You can chop all your veggies ahead of time. You can also cook the chicken and rice a day or two in advance. You could even mix the whole casserole together (steps 2-4) and store it in the greased baking dish in the fridge for up to 24 hours before adding the cheese and baking. Just add a few extra minutes to the baking time if baking from cold.
How to Store It
Got leftovers? Lucky you! This casserole stores really well.
Simply cover the cooled casserole dish tightly with plastic wrap or aluminum foil, or transfer individual portions to airtight containers. It will keep in the refrigerator for 3-4 days.
For longer storage, you can freeze the cooled casserole. You can freeze the whole dish (if using a freezer-safe dish) wrapped tightly in plastic wrap and then foil, or freeze individual portions in freezer-safe containers. It should keep well in the freezer for up to 2-3 months. Thaw overnight in the refrigerator before reheating.
To reheat, you can warm individual portions in the microwave. For larger amounts, cover loosely with foil and reheat in a 300°F (150°C) oven until heated through.
