Ingredients You’ll Need

Gathering your ingredients for this Teriyaki beef casserole is refreshingly simple. Each item plays a key role, whether it’s building the rich, savory-sweet sauce, adding texture, or delivering a pop of color to this vibrant dish.

• Low-sodium soy sauce: This is the salty backbone of your teriyaki sauce, keeping it flavorful without overpowering the other tastes.
• Water: Helps balance the sauce, ensuring it’s not too intense and allowing for proper marinade consistency.
• Brown sugar: Adds a deep, caramel-like sweetness that complements the beef perfectly.
• Garlic powder: Gives a subtle, aromatic punch without the sharpness of fresh garlic.
• Sesame oil: Delivers a toasty, nutty aroma that elevates the flavor to authentic heights.
• Flank steak: Tender, lean, and with just the right chew, it absorbs the marinade beautifully.
• Cornstarch: The secret to thickening the teriyaki sauce into that glossy coating we all adore.
• Canola oil: Provides a neutral base for searing the beef to a perfect crust without burning.
• Cooked rice: The hearty comfort base that soaks up all the savory sauce and juices.
• Mixed vegetables (broccoli, carrots, baby corn, cauliflower): Adds color, crunch, and nutrition to the casserole.
• Scallion: A fresh, sharp garnish that brightens the dish.
• Sesame seeds: Adds a delightful toasted crunch and an extra layer of nuttiness at the end.

How to Make Teriyaki beef casserole

Step 1: Prepare the Beef and Marinade

Start by slicing the flank steak against the grain into bite-sized pieces. This is important because cutting against the grain ensures each bite is tender and easy to chew. Next, whisk together low-sodium soy sauce, water, brown sugar, garlic powder, and sesame oil in a bowl to create the marinade. Fully submerge the beef in this savory-sweet mixture and let it soak up the flavors for at least 30 minutes, though up to 6 hours will deepen the taste beautifully.

Step 2: Make the Cornstarch Slurry

While the beef marinates, combine cornstarch with water to create a slurry. This simple mixture is essential as it will thicken the teriyaki sauce later, transforming it from a runny liquid to a glossy glaze that clings to every delicious component in the casserole.

Step 3: Sear the Beef

Heat canola oil in a large oven-safe skillet over high heat. Scoop the steak out from the marinade, reserving the marinade for the sauce. Quickly sear the beef pieces on all sides, about 1 minute per side, until they develop a caramelized exterior. This step locks in the juices and adds a satisfying depth of flavor through Maillard browning.

Step 4: Build the Sauce and Combine Ingredients

Pour the reserved marinade into the skillet with the seared steak and bring it to a boil. Then lower the heat and whisk in the cornstarch slurry. As the mixture simmers, it will thicken into a beautiful syrupy teriyaki sauce in just a few minutes. Toss in the cooked rice first, stirring well to ensure every grain is coated. Next, fold in the mixed vegetables, letting them mingle beautifully with the meat and rice mixture.

Step 5: Bake and Broil to Finish

Transfer the skillet to a preheated 350-degree oven and bake for 15 minutes. This allows the flavors to meld and the vegetables to soften while still holding a slight bite. After baking, scatter the seared steak pieces on top and broil the casserole for an additional 5 minutes. This final step crisps up the beef in a mouthwatering way that adds irresistible texture.

Garnishes

The finishing touches truly elevate your Teriyaki beef casserole. A sprinkle of thinly sliced scallions adds a fresh and mildly sharp contrast to the rich sauce, while toasted sesame seeds lend subtle crunch and nuttiness. These simple garnishes bring color, texture, and an inviting aroma that makes the dish look as good as it tastes.

Side Dishes

While the casserole can easily be a standalone meal, pairing it with light sides complements its rich flavor. Steamed bok choy or snap peas work wonderfully for a crisp, fresh counterpart. A simple cucumber salad with a hint of rice vinegar can also brighten the palate and balance the savory meat and sauce.

Creative Ways to Present

For a fun twist, serve the casserole in individual ramekins or mini cast-iron skillets to impress guests at dinner parties. You could also layer the casserole with additional steamed vegetables or even a light drizzle of spicy mayo to add a creamy, piquant edge. Whichever way you choose, presentation is your playground with this versatile Teriyaki beef casserole.

Make Ahead and Storage

Storing Leftovers

Cool leftover Teriyaki beef casserole completely before transferring it to an airtight container. Stored in the refrigerator, it will keep well for up to 3 days, allowing you to enjoy the flavors without any sacrifice in taste or texture.

Freezing

You can freeze the casserole for longer storage. Place portions in freezer-safe containers or zip-top bags, removing as much air as possible. It will hold up beautifully for up to 2 months. Thaw overnight in the fridge before reheating for best results.

Reheating

Reheat your Teriyaki beef casserole gently in a microwave or oven. If using a microwave, cover the dish loosely to retain moisture and heat in 1-2 minute intervals. For an oven, warm it at 325 degrees until heated through, adding a sprinkle of water to keep the rice moist if needed.

FAQs

Can I use other cuts of beef for this Teriyaki beef casserole?

Absolutely! While flank steak is perfect for this dish due to its tenderness and flavor absorption, you can substitute skirt steak or sirloin. Be mindful to slice against the grain and adjust cooking times to avoid toughness.

Is it possible to make this casserole gluten-free?

Yes! Simply use gluten-free tamari instead of soy sauce. Most other ingredients are naturally gluten-free, but always double-check labels to be sure.

Can I add more vegetables to the Teriyaki beef casserole?

Definitely. Feel free to include bell peppers, snap peas, mushrooms, or any veggies you love. Just make sure to cut them into bite-sized pieces and adjust cooking times to maintain good texture.

How long should I marinate the beef for the best flavor?

Marinating for at least 30 minutes will infuse nice flavor, but if you have time, letting it sit for up to 6 hours deepens the taste even more. Avoid marinating overnight as the texture of the meat might be affected.

Can I prepare this casserole ahead of time and bake it later?

Yes, you can assemble the casserole up to the point before baking and refrigerate it for a few hours. When you’re ready, bake as directed, adding a few extra minutes to ensure it’s heated through.
