This Ground Beef Chow Mein Casserole is what happens when a weeknight noodle bake meets the savory depth of a good stir-fry — and it completely works. It’s got soy sauce, fresh ginger, loads of vegetables, and that bubbling golden Cheese on top that makes a casserole feel like a casserole. Not traditional, not trying to be. Just really, really good.
Why You’ll Love It
- One pan, then the oven — everything comes together in a single skillet before it bakes, so cleanup is minimal and the whole thing is hands-off once it goes in.
- Packed with vegetables — cabbage, carrots, celery, and mushrooms all cook down into the noodles so you’re getting a full meal in every bite.
- Big savory flavor — soy sauce, oyster sauce, sesame oil, and fresh ginger do the heavy lifting here. It tastes way more complex than the ingredient list suggests.
- Feeds a crowd without drama — a 9×13 dish goes a long way, and it reheats beautifully the next day (the noodles soak everything up overnight and it gets even better).
- Easy to customize — swap the protein, change up the vegetables, skip the cheese or lean into it. It’s a very forgiving recipe.
A Few Notes on Ingredients
The noodles: I’ve made this with actual chow mein noodles when I can find them (the refrigerated kind, not the crunchy ones in a can — though I’ve used those in a pinch and it’s fine, just different), and I’ve also made it with regular spaghetti broken in half and cooked to just barely al dente. Honestly, the spaghetti version is what I make most of the time because I always have it in the pantry.
Oyster sauce: the recipe says optional, but I’d say don’t skip it if you have it. It adds this dark, almost sweet-savory thing that’s hard to replicate. I use Lee Kum Kee, whatever’s at my grocery store, nothing fancy.
The cabbage: I know it seems like a lot but it cooks down to almost nothing, and you’ll miss it if you cut back too much. I’ve used both green and napa cabbage, and both are great. Napa gets a little silkier.
Cheese on top: this is where people give me the look. The “why is there cheese on your chow mein” look. And I get it. But — just trust me. The cheddar gets all bubbly and golden and it sort of pulls everything together into something that feels unified in a way you wouldn’t expect. If it really offends your sensibilities, skip it. But try it once first.
Ginger: please grate it fresh. The stuff in the jar is convenient and I’ve used it when I’m desperate, but there’s no comparison. Fresh ginger has this almost peppery brightness that the jarred stuff just doesn’t have.
Ingredients
- 1 pound ground beef
- 1 medium onion, diced
- 2 cloves garlic, minced
- 1 tablespoon fresh ginger, grated (I usually do a little more — maybe a heaping tablespoon)
- 1 cup celery, chopped
- 1 cup carrots, julienned (or just roughly cut)
- 3 cups cabbage, thinly sliced
- 8 ounces mushrooms, sliced
- 8 ounces cooked chow mein noodles or spaghetti
- 3 tablespoons soy sauce
- 1 tablespoon oyster sauce — don’t skip it
- 1 teaspoon sesame oil
- 2 tablespoons vegetable oil
- 1 cup beef broth
- 1 tablespoon cornstarch
- 1 cup cheddar cheese, grated (optional, but really consider it)
- Salt and pepper to taste
- Green onions or chives for the top
How to Make It
Start by preheating your oven to 350°F. Grease a 9×13 baking dish — I use whatever cooking spray is within reach, but butter works too.
Get a big skillet going over medium heat with your vegetable oil. When it shimmers, add the ground beef and break it up as it cooks. I like it browned in some spots, not just grey. There’s a difference. Let it actually sit for a minute before you start stirring. While that’s going, I usually grate my ginger right then because I always forget to do it ahead of time.
Once the beef is done, add the onion, garlic, and ginger right into the pan — don’t drain the fat unless there’s an alarming amount of it. Cook until the onions go soft and translucent, which takes maybe five minutes.
Toss in the celery and carrots and give it a few minutes. Then the cabbage and mushrooms. This is the part where everything looks like too much and you second-guess yourself — just keep stirring, it’ll all wilt down.
In a small bowl, whisk together the broth, soy sauce, oyster sauce, sesame oil, and cornstarch until no lumps remain. Pour that over everything in the skillet, stir well, and let it come to a simmer. It’ll thicken up fairly quickly — maybe two or three minutes.
Now add your cooked noodles. Toss everything together gently. I use tongs for this. It should look cohesive, not soupy.
Transfer the whole mixture into your prepared baking dish, top with the cheddar if you’re using it, and slide it into the oven for 20 to 25 minutes. You want the cheese bubbly and just starting to get golden at the edges. When you pull it out, let it sit for five minutes before you serve it — it holds together better that way.
Scatter the green onions over the top right before serving.
Variations
Ground turkey works great here if you’re skipping beef. It’s a little lighter in flavor, so add a touch more soy sauce and maybe a splash more sesame oil at the end to compensate.
If you want to go meatless, skip the beef entirely and double the mushrooms — or add a block of firm tofu, cubed and pressed first. Use vegetable broth instead of beef broth. It’s a totally different dish but a good one.
I’ve thrown in bean sprouts at the very end, just tossed them in with the noodles so they stay a little crunchy. Water chestnuts work the same way and add a nice bite.
Bell peppers, shredded bok choy, snap peas — really, whatever’s in your crisper drawer that needs to be used. That’s how half my variations were invented.
Leftovers
It keeps in the fridge for three, maybe four days. To reheat, add a tiny splash of water or broth before microwaving, or warm it in a covered skillet over low heat. The noodles will have absorbed everything by the next day, so it’ll be a bit drier than fresh — the extra liquid helps.
I’ve frozen it, but the noodles get soft and a bit mushy when it thaws. Edible, just not ideal. If you know you’re going to freeze it, maybe hold back a third of the noodles and cook fresh ones when you reheat.
Final Notes
Once you make this, don’t be surprised when someone asks for the recipe. It has that effect.
Serve it with green beans if you have them, or just eat it straight out of the baking dish standing over the sink. No judgment.
