What Makes This Casserole Korean-Inspired?
The sauce uses garlic, ginger, soy sauce, toasted sesame oil, and gochujang—a Korean fermented chili paste with savory depth and a touch of sweetness.
This is a Korean-inspired family casserole rather than a traditional Korean dish. It combines those flavors with the familiar comfort of a beef, broccoli, and rice bake.
Ingredients
For the Casserole
- 1½ pounds lean ground beef, preferably 90/10
- 1 small yellow onion, finely diced
- 5 garlic cloves, minced
- 1 tablespoon freshly grated ginger
- 4 cups cooked jasmine rice
- 5 cups fresh broccoli florets, cut into small, bite-size pieces
- ¼ teaspoon black pepper
- 1 teaspoon neutral cooking oil, if needed
- Sliced green onions, for serving
- Toasted sesame seeds, for serving
For the Korean-Inspired Sauce
- ½ cup low-sodium soy sauce
- ¾ cup low-sodium beef broth
- 3 tablespoons packed brown sugar
- 1–2 tablespoons gochujang, depending on your preferred heat
- 1 tablespoon unseasoned rice vinegar
- 2 teaspoons toasted sesame oil
- 1 tablespoon cornstarch
Rice note: Measure the rice after cooking. This recipe requires 4 cups cooked rice, not 4 cups dry rice. If cooking it fresh, prepare about 1½ cups dry jasmine rice according to the package directions, then measure out what you need.
Ingredient Tips
Ground beef: Lean ground beef keeps the casserole flavorful without leaving excess grease in the rice. Drain the skillet after browning if needed.
Broccoli: Small florets distribute evenly and are easier to scoop. Briefly steam them before assembling so they finish tender without needing a long bake.
Gochujang: Heat and salt levels vary by brand. Use 1 tablespoon for a gentler flavor or 2 tablespoons for a stronger chili kick.
Cooked rice: Freshly cooked rice and properly refrigerated leftover rice both work. Break up any cold clumps before mixing.
Low-sodium soy sauce and broth: These help keep the sauce balanced, especially because gochujang also contains salt.

How to Make Korean Beef and Broccoli Rice Casserole
1. Brown the Beef and Onion
Preheat the oven to 375°F. Lightly grease a 9×13-inch baking dish.
Cook the ground beef and diced onion in a large skillet over medium-high heat for 7–9 minutes, breaking the beef into crumbles, until fully cooked. Drain excess grease.
Stir in the garlic, ginger, and black pepper. Cook for another 30–60 seconds, until fragrant.
2. Assemble the Casserole
Whisk together the soy sauce, beef broth, brown sugar, gochujang, rice vinegar, sesame oil, and cornstarch.
Add the cooked beef mixture, 4 cups cooked rice, and raw broccoli to the baking dish. Pour the sauce over everything, stir thoroughly, and spread into an even layer.
Cut the broccoli into small florets, about 1 inch, so it cooks evenly.
3. Cover and Bake
Cover tightly with foil and bake for 25–30 minutes, until the broccoli is tender and the casserole is hot throughout.
If the broccoli needs more time, stir, cover again, and bake for another 5–10 minutes.
4. Finish and Serve
Stir gently to distribute the sauce. Let rest for 5 minutes, then sprinkle with sliced green onions and sesame seeds.
Tips for the Best Beef and Broccoli Rice Casserole
- Brown the beef well. Let it develop some color before breaking it into smaller pieces.
- Use cooked rice. Uncooked rice won’t absorb enough liquid during this short bake.
- Keep the dish covered. The foil traps moisture and helps the rice stay tender.
- Finish with fresh toppings. Green onions add freshness, and sesame seeds add a little texture.
Easy Variations
Make It Milder
Use 1 teaspoon gochujang, or leave it out for a mild soy, garlic, and ginger casserole. Serve chili paste separately so everyone can adjust their own portion.
Add More Vegetables
Stir in a handful of shredded carrots or sautéed mushrooms. Cook watery vegetables first so they don’t thin the sauce.
Use Brown Rice
Substitute 4 cups fully cooked brown rice. Keep the sauce quantities and baking method the same.
Swap the Ground Beef
Ground turkey or ground chicken also works. Add a little neutral oil to the skillet if the meat is very lean.
Add a Cheesy Topping
For a cheesy variation, sprinkle 1 cup shredded mozzarella over the assembled casserole. Bake covered, then uncover for the final 5 minutes to finish melting the cheese.
What to Serve with Korean Beef and Broccoli Rice Casserole
This casserole already includes your protein, vegetables, and rice, so a fresh or tangy side is all you need.
Try sliced cucumbers tossed with rice vinegar, a little sesame oil, and a pinch of salt. Kimchi, steamed edamame, or a simple cabbage slaw also pairs well.
For a larger dinner spread, serve smaller portions alongside gyoza meatballs or shrimp and snow pea stir fry.

Notes
- Use cooked rice: The 4 cups of rice are measured after cooking. Uncooked rice will not work with these liquid quantities and baking times.
- No steaming required: Add the broccoli raw. Cut it into small, approximately 1-inch florets and cover the dish tightly so it cooks evenly.
- Adjust the heat: Start with 1 tablespoon gochujang for less heat or use 2 tablespoons for a stronger chili flavor. Heat varies by brand.
- Cold rice: Break up refrigerated rice before mixing. It may require additional baking time.
- Timing: Prep and total times assume the rice is already cooked. Allow additional time if preparing rice from scratch.
- Frozen broccoli: Thaw and drain thoroughly before adding it to the casserole.
Storage and Reheating
Refrigerator: Divide leftovers into shallow containers and refrigerate within 2 hours. Use within 3–4 days; if you started with leftover rice, count from the day that rice was originally cooked.
Freezer: Freeze cooled portions in airtight containers for up to 2 months for best texture. Thaw in the refrigerator before reheating.
Reheating: Add a small splash of water or broth, cover, and reheat until the center reaches 165°F. Stir individual portions partway through heating to help them warm evenly.
Frequently Asked Questions
Can I use frozen broccoli?
Yes. Partially cook it according to the package directions, just until you can separate the florets, then drain thoroughly. Cut large pieces smaller before adding them to the casserole.
Can I use microwave rice?
Yes. Prepare it according to the package instructions and measure out 4 cups. Plain jasmine rice or long-grain white rice works well.
Do I have to use gochujang?
No. You can leave it out for a milder casserole. The sauce will still have plenty of garlic, ginger, soy, and sesame flavor, though it will lose some of its chili depth.
Is this casserole spicy?
That depends on your gochujang. Start with 1 tablespoon if you’re unsure, and use less for heat-sensitive eaters. You can always add more to individual servings.
Why is my casserole dry?
Too much rice, too little sauce, or baking uncovered can dry it out. Measure the cooked rice, use all the sauce, and cover the dish tightly. If the mixture looks dry before baking, stir in an additional 2–4 tablespoons of broth.
Final Thoughts
This Korean-inspired beef and broccoli rice casserole brings a savory, garlicky twist to an easy family dinner. The ground beef keeps it affordable, the broccoli makes it a complete meal, and the sesame-gochujang sauce gives the rice plenty of flavor.
