Ingredients
- 3/4 cup low-sodium soy sauce
Soy sauce is the key ingredient in any teriyaki sauce, providing that deep, salty umami flavor. Using low-sodium soy sauce helps control the salt content without sacrificing flavor, which is especially important when cooking for a crowd or managing your sodium intake. - 1/2 cup water
The water helps thin out the soy sauce, allowing for a smoother texture in the sauce. This gives the sauce the perfect consistency for drizzling over the casserole ingredients and ensures it will coat everything evenly. - 1/4 cup light brown sugar
Brown sugar adds the sweetness that balances out the salty soy sauce. It also adds a hint of molasses flavor, which deepens the overall taste of the teriyaki sauce and gives it that familiar, comforting sweetness we associate with teriyaki dishes. - 1/2 teaspoon ground ginger
Ginger brings a warm, aromatic kick to the sauce. Its slightly spicy, earthy flavor complements the sweetness of the brown sugar and the saltiness of the soy sauce, creating the perfect harmony of flavors. - 1/2 teaspoon minced garlic
Garlic adds depth and savory complexity to the sauce. It infuses the teriyaki with its unmistakable flavor and works hand in hand with the ginger to create that classic Asian-inspired taste. - 2 Tablespoons cornstarch + 2 Tablespoons water
The cornstarch mixture is used to thicken the teriyaki sauce. When combined with water and heated, it creates a smooth, glossy consistency that coats the ingredients perfectly. This is what makes the sauce cling to the beef and vegetables, adding flavor to every bite. - 1 bag (12 ounces) refrigerated stir-fry vegetables
The pre-packaged stir-fry vegetables typically contain a mixture of broccoli, carrots, snow peas, and sometimes bell peppers or other colorful veggies. These vegetables not only add nutritional value but also bring color, texture, and freshness to the casserole. Their natural sweetness contrasts nicely with the savory flavors in the dish. - 1 pound lean ground beef
Ground beef is the protein backbone of this casserole. The lean variety is perfect for this dish as it provides the meaty, satisfying element without too much fat. It crumbles easily and mixes well with the other ingredients, ensuring that every bite has a bit of beef in it. - Salt and pepper, to taste
Seasoning with salt and pepper enhances the natural flavors of the beef and vegetables. The salt will also help bring out the depth of flavor in the homemade teriyaki sauce. - 3 cups cooked rice
Rice is the perfect base for this casserole, and jasmine rice is an excellent choice for its fragrant aroma and tender texture. It helps absorb the sauce and balances out the bold flavors in the dish.
Instructions
- Preheat the oven to 350°F (175°C) and spray a 9×13-inch baking dish with non-stick spray. The oven should be preheated while you prepare the ingredients, ensuring that it’s ready to go when it’s time to bake the casserole.
- Make the teriyaki sauce: In a small saucepan, combine the soy sauce, water, brown sugar, ground ginger, and minced garlic. Cover the saucepan and bring the mixture to a boil over medium heat. Once it reaches a boil, remove the lid and let it cook for about 1 minute. This will help the flavors meld together and the sauce to reduce slightly.
- Thicken the sauce: While the sauce is boiling, stir together the cornstarch and water in a small dish until smooth. Once the sauce has been boiling for a minute, slowly add the cornstarch mixture to the saucepan, stirring continuously to avoid lumps. Continue to cook the sauce until it thickens, which should take a few minutes. Once thickened, remove the saucepan from heat and set it aside.
- Prepare the vegetables: Spread the stir-fry vegetables evenly across the bottom of the prepared baking dish. These vegetables will provide texture and flavor, absorbing the delicious teriyaki sauce as they bake. Pour 3/4 cup of the teriyaki sauce over the vegetables, ensuring that they are coated well.
- Bake the vegetables: Cover the baking dish with aluminum foil and bake for 35 minutes, or until the vegetables are tender. The foil traps steam and helps the vegetables cook evenly, while the teriyaki sauce will start to infuse into them, creating a flavorful base for the casserole.
- Cook the ground beef: While the vegetables are baking, heat a large skillet over medium-high heat and add the ground beef. Season the beef with salt and pepper to taste. Cook the beef, breaking it up with a spoon, until it is no longer pink. Drain any excess grease, then set the beef aside.
- Assemble the casserole: Once the vegetables are tender, remove the baking dish from the oven and carefully remove the foil. Pour the cooked ground beef and cooked rice evenly over the vegetables. The beef will add richness, while the rice acts as a base to absorb the sauce and balance the dish’s flavors. Drizzle most of the remaining teriyaki sauce over the top, reserving a little for serving. Gently toss everything together until combined.
- Finish baking: Return the casserole to the oven and bake uncovered for an additional 10 minutes, or until everything is heated through. The rice should absorb some of the sauce, and the beef and vegetables will blend beautifully, creating a cohesive dish.
- Serve and enjoy: Once done, remove the casserole from the oven and let it sit for about 5 minutes before serving. Drizzle each serving with the remaining teriyaki sauce, and enjoy the satisfying flavors and textures of this easy, delicious meal.
Notes
- Vegetables: If you don’t have pre-packaged stir-fry vegetables, you can use whatever vegetables you like. Bell peppers, onions, or even baby corn would be great alternatives. Feel free to experiment with different combinations based on what you have available.
- Protein: If you prefer a different type of protein, you can swap the ground beef for ground turkey, chicken, or even tofu for a vegetarian version. If using tofu, press it well to remove excess moisture before cooking.
- Rice: While jasmine rice is the preferred choice for its fragrance and texture, you can substitute it with other types of rice, such as brown rice or white rice. Quinoa or cauliflower rice can be used for a low-carb alternative.
- Teriyaki Sauce: If you prefer a sweeter or spicier sauce, adjust the brown sugar or add a dash of red pepper flakes to the sauce for a bit of heat. You can also make a gluten-free version by using tamari instead of soy sauce and ensuring your cornstarch is certified gluten-free.
