Substitutions that hold up: cuts, sweeteners, soy
Okay. We've done the marinade, we've done the meat, we've timed everything. Now let's talk about what happens when you get to the fridge and something's missing.
Because it will happen. You'll be halfway into dinner and realize you're out of brown sugar, or the only beef at the store is a cut you don't recognize, or your soy sauce situation is weird. That's normal. Cooking at home is a logistics problem and substitutions are part of solving it. I'm not going to pretend every swap is as good as the original — some of them aren't — but a lot of them are fine, and I'll tell you straight which is which.
Cuts of beef
Traditional bulgogi is ribeye, thin sliced. That's what you'll get pre-sliced at the Korean grocery up in Salt Lake, and if you can get that, heck yes, use it.
But you're not always going to have that on hand, or the budget for it, and here's what actually holds up:
- Sirloin — this is my go-to backup. Less fat than ribeye, still tender if you slice it thin and against the grain, marinade works into it fine.
- Flank steak — leaner, a little more chew, but the marinade helps a lot here. Slice thin, no exceptions on this one, the grain runs long on flank and if you don't cut against it you'll be chewing forever.
- Chuck roast, sliced thin — this surprises people. It's a tougher cut but it's got enough fat running through it that the marinade and quick high heat cooking actually tenderizes it well. Ask the meat counter to slice it for you if your knife skills aren't there yet. Most will do it for free if you ask nicely.
What doesn't work well: anything already stew-cut or thick chunked. Bulgogi is a quick-cook method. Thick cuts just don't get there in the time you're giving them in the pan, and you end up with something tough on the outside and pink and cold in the middle. If all you've got is a roast, slice it yourself, thin, partially frozen if you need to steady it for the knife. That trick works — twenty minutes in the freezer firms the meat up enough that thin slicing is way easier.
Sweeteners
Traditional recipes use sugar, sometimes with pear or apple in the marinade for extra sweetness and tenderizing. Here's the substitution order I actually use, best to worst:
- Brown sugar — my regular pick, and what's on your pantry list already.
- Honey — works, but it browns faster in the pan, so watch your heat, it'll catch and burn before the sugar version would.
- Regular white sugar — fine in a pinch, does the job, just doesn't add the same depth.
- Grated pear or apple — this isn't really a substitute, it's an addition, and if you've got a pear going soft in the fridge, grate a quarter of it into the marinade along with your sugar. Old trick, tenderizes the meat a little more too.
Don't skip the sweetener entirely thinking you're doing yourself a favor. It's not just for taste, it balances the saltiness of the soy and it helps the meat caramelize properly in the pan. Without it the bulgogi tastes flat and looks pale instead of getting that little bit of char.
Soy sauce
Here's the thing — soy sauce is not one thing. Korean soup soy sauce (guk-ganjang) is different from the all-purpose soy sauce you use for marinades, and they are not interchangeable, so don't grab the wrong bottle off the shelf at the Asian market thinking soy sauce is soy sauce. For bulgogi you want regular soy sauce, the all-purpose kind.
If all you have is a Kikkoman bottle from Macey's, that's fine. It's saltier and a touch sharper than Korean brands, so I'd back off the amount slightly, maybe three-quarters of what the recipe calls for, and taste before you add more.
Low sodium soy sauce works fine too if that's what your household uses. You may need to add a little more, since you're diluting the salt, but it won't wreck the dish.
What I would not do is substitute soy sauce with coconut aminos or a "soy-free" alternative and expect the same result. They're thinner, sweeter, and missing that deep fermented flavor that soy sauce brings. That's fine if you've got an allergy in the house and it's what you've got to work with — I'd rather you make bulgogi with coconut aminos than not make it at all. Just know going in that it'll taste different, not worse necessarily, just different. Don't blame the recipe.
Don't overthink it
I know that's a lot of detail for what's supposed to be a simple swap-this-for-that lesson. Write down the ones that apply to your kitchen and forget the rest.
The first time I made a full spread the way my mom used to — rice, bulgogi, three banchan, soup, everything out on the table at once — I stood back and looked at it and felt like I'd finally gotten it right. Years of writing things down, timing things, figuring out what actually works in my own kitchen instead of my mom's, and there it was. Then Bronson asked if there were chicken nuggets.
That's the job. You get it right, mostly, and somebody still wants nuggets. Substitutions are the same deal — you're not chasing perfect, you're chasing something that gets dinner on the table and tastes like what you were going for. Most of these swaps get you there.
Before next time: check what beef is actually in your fridge or freezer right now and figure out which substitution applies to you. Come next class ready to tell me what cut you're working with.
