Ingredients

Here’s what you’ll need to gather from your pantry and fridge. The beauty of this recipe is it often uses things you already have!

  • 2 cups cooked chicken, shredded or cubed: Leftover rotisserie chicken or cooked chicken breast works perfectly here. This is your protein power-up!
  • 2 cups cooked rice: Again, leftovers are your friend! Any kind of cooked rice works – white, brown, jasmine, basmati.
  • 1 cup carrots, sliced: Adds a lovely sweetness and crunch. Feel free to use coin slices or small sticks.
  • 1 cup bell peppers, chopped (any color): Pick your favorite color or mix them up for a vibrant dish! They add great flavor and nutrients.
  • 1 cup broccoli florets, steamed: I like to give these a quick steam or blanch so they’re slightly tender before going into the bake.
  • 1 cup frozen peas, thawed: Just grab them from the freezer and let them sit out for a few minutes, or give them a quick rinse under warm water. Easy peasy!
  • 1/2 cup teriyaki sauce (store-bought or homemade): Use a good quality sauce you love. This is where a lot of the flavor comes from!
  • 1 cup shredded mozzarella cheese: For that bubbly, golden, cheesy goodness on top. You can’t go wrong with mozzarella!
  • 1/4 cup soy sauce: Adds that essential umami depth and saltiness.
  • 2 tablespoons olive oil: For greasing the dish and adding a little richness.
  • 1 teaspoon garlic powder: An easy way to add garlic flavor throughout the dish.
  • 1 teaspoon onion powder: Just like the garlic powder, it distributes flavor beautifully.

How to Make It

Alright, let’s get this casserole party started! It’s truly as simple as mix, dump, and bake.

  1. First things first, you’ll want to get your oven ready. Preheat it to 350°F (175°C). While it’s warming up, grab your trusty 9×13 inch baking dish. Give it a light grease with a little bit of that olive oil. This helps prevent sticking and makes serving (and cleaning!) much easier.
  2. Now, grab the biggest mixing bowl you have. Into this bowl goes your cooked chicken, cooked rice, sliced carrots, chopped bell peppers, steamed broccoli, and thawed peas. It should look like a colorful party in the bowl!
  3. Next, it’s time to add the flavor powerhouses. Pour in the teriyaki sauce, soy sauce, garlic powder, and onion powder. Now, take a big spoon or spatula and stir everything together really well. Make sure every piece of chicken, every grain of rice, and all those lovely veggies are coated in that delicious teriyaki sauce mixture. You want the flavor distributed evenly!
  4. Carefully transfer the whole mixture from the bowl into your prepared baking dish. Use your spoon to spread it out into an even layer. You want it to bake consistently.
  5. Sprinkle that wonderful shredded mozzarella cheese all over the top. Get it right up to the edges! This is going to create a bubbly, melty crust.
  6. Cover the dish snugly with aluminum foil. Pop it into your preheated oven and bake for about 25-30 minutes. You’ll know it’s ready when the vegetables are nice and tender, and you can see the cheese underneath starting to melt and bubble up.
  7. Now for the grand finale! Carefully remove the foil. This allows the cheese to get nice and golden and maybe even a little crispy in spots. Put the dish back in the oven, uncovered, for another 5 minutes or so. Keep an eye on it during this step, as ovens can vary.
  8. Once it’s out of the oven, the cheese will be gorgeously golden and bubbly. It’s going to be super hot, so let it cool down for just a few minutes before you scoop it out and serve. This helps everything set a little and prevents burnt tongues!

Substitutions & Additions

Feeling creative? This casserole is super forgiving and adaptable. Here are a few ideas:

  • Swap the Protein: No chicken? Cooked shrimp, cubed firm tofu (pressed well), or even leftover cooked pork would work here. Just make sure they’re already cooked.
  • Veggie Swap: Use whatever non-starchy veggies you have on hand! Sautéed mushrooms, spinach (just wilt it in before mixing), snap peas, green beans, or water chestnuts would be delicious additions.
  • Make it Spicy: Add a dash of sriracha or a pinch of red pepper flakes to the sauce mixture for a kick.
  • Different Cheese: Provolone or even a mix of mozzarella and cheddar could work, though mozzarella gives that classic melt.
  • Garnish Ideas: Sprinkle with toasted sesame seeds, chopped green onions, or a drizzle of extra teriyaki sauce before serving for extra flavor and visual appeal.

Tips for Success

Making this casserole is pretty straightforward, but here are a couple of little things I’ve learned along the way:

  • Use Cooked Ingredients: This recipe is designed for pre-cooked chicken and rice, and pre-steamed or blanched veggies like broccoli. This ensures everything heats through evenly and you don’t end up with hard carrots or raw broccoli.
  • Don’t Skip the Stirring: Make sure that sauce is really coating everything in the bowl. This is how you get flavor in every single bite.
  • Prep Ahead: You can mix the chicken, rice, veggies, and sauce together in the baking dish (or a bowl) up to a day in advance. Cover it tightly and keep it in the fridge. When you’re ready to bake, just add the cheese and bake as directed, you might need an extra 5-10 minutes on the covered bake time since it’s going in cold.

How to Store It

Got leftovers? You’re in luck! This casserole stores beautifully.

Let the casserole cool completely before storing. Transfer any leftovers to an airtight container and keep it in the refrigerator for 3-4 days. To reheat, you can microwave individual portions or place a larger amount in an oven-safe dish, cover, and reheat at 325°F (160°C) until heated through.

FAQs

Let’s answer a couple of quick questions you might have!

Q: Can I use raw chicken?
A: This recipe calls for cooked chicken. If you’re starting with raw chicken, you’ll need to cook and shred or cube it before adding it to the mix. Baking the casserole won’t be enough time to cook raw chicken thoroughly.

Q: Can I use a different kind of rice?
A: Absolutely! White rice, brown rice, jasmine, basmati – as long as it’s cooked, it will work great in this casserole.

Q: Is this casserole spicy?
A: As written, no. Teriyaki sauce is generally sweet and savory. If you like heat, feel free to add some sriracha or red pepper flakes to the sauce mixture.

Q: Can I freeze this casserole?
A: Yes, you can! You can assemble the casserole (without the cheese topping), cover it tightly with plastic wrap and then foil, and freeze for up to 2-3 months. Thaw it overnight in the fridge before adding the cheese and baking as directed (you may need to add some extra baking time). You can also freeze individual leftover portions.

Notes

Substitutions & Additions: Swap chicken for cooked shrimp, cubed firm tofu, or leftover cooked pork. Use other non-starchy veggies like sautéed mushrooms, spinach, snap peas, green beans, or water chestnuts. Add sriracha or red pepper flakes for spice. Provolone or a mozzarella/cheddar mix can be used instead of just mozzarella. Garnish with toasted sesame seeds, chopped green onions, or extra teriyaki sauce.
Tips for Success: Ensure chicken, rice, and denser veggies (like broccoli) are pre-cooked. Stir well to evenly distribute flavor. Can be prepped up to a day ahead (mix ingredients and sauce, store covered in fridge, add cheese before baking - may need extra bake time).
How to Store: Let cool completely. Store leftovers in an airtight container in the refrigerator for 3-4 days. Reheat individual portions in the microwave or larger amounts covered in an oven-safe dish at 325°F (160°C) until heated through.
FAQs: This recipe requires cooked chicken and rice. Any type of cooked rice works. It is not spicy as written, but spice can be added. The casserole can be frozen assembled (without cheese) for 2-3 months; thaw overnight in fridge before baking.
