Broiled flank steak is the easiest steak dinner of the week: a 4-ingredient marinade, 12 minutes under the broiler, no grill required. From a dietitian mom of four.
I love a grilled steak as much as anyone, but on a busy weeknight? I’m not always interested in standing outside at the grill — especially when it’s cold, raining, or I’m running between practices, homework, and everything else that seems to happen right around 5 p.m.
That’s why broiled flank steak has become one of my favorite shortcuts. You still get that flavorful, slightly charred outside and tender, juicy steak inside, but everything happens right in your oven.
And flank steak is perfect for my favorite kind of dinner: cook one thing and use it a few different ways. Slice it up and serve it with roasted potatoes and veggies, tuck it into tacos, add it to a rice bowl, or save the leftovers for salads and wraps the next day.
Why Flank Steak Is the Cut I Keep Buying
Three reasons, and they’re all practical.
- It’s one of the cheaper steaks. Flank runs well under what you’d pay for ribeye or filet, and one steak feeds our whole crew with leftovers.
- It’s lean. About 23 grams of protein in a 3-ounce cooked serving, with less saturated fat than the marbled cuts. It’s a genuinely good weeknight protein, not a splurge.
- It was built for marinade. Flank is a hard-working muscle with the grain running in one obvious direction, which means it soaks up flavor better than almost any other cut and tenderizes while it sits.
The tradeoff: flank punishes you for overcooking it and for slicing it wrong. Both of those are easy to get right, and I’ll show you exactly how below.
The marinade is intentionally simple, too. No long ingredient list and no complicated prep — just a few pantry staples, a little time to marinate, and about 12 minutes under the broiler.
Because sometimes the best weeknight dinner isn’t a brand-new idea. It’s just an easier way to make something your family already loves.
The 4-Ingredient Marinade
No specialty ingredients. This is soy sauce, olive oil, honey, and a lot of garlic, and it is the same marinade base I’ve been using for years.
- 1/3 cup low-sodium soy sauce
- 2 tablespoons olive oil
- 2 tablespoons honey
- 4 cloves garlic, minced (or 1 tablespoon jarred — nobody is checking)
- 1/2 teaspoon black pepper
Whisk it, pour it over a 1.5 to 2 pound flank steak in a zip-top bag, push the air out, and refrigerate. Two hours is enough. Overnight is better. I usually do it in the morning while I’m packing lunches, which is the only reason it ever actually happens.
One note: don’t go past 24 hours. The salt and acid keep working and the texture turns mealy. If you want the grilled version of this same idea, that’s over on my grilled garlic lime flank steak post.
How to Broil Flank Steak
The broiler is direct radiant heat from above, usually somewhere around 500 to 550 degrees. That’s grill heat. The whole method is: get the rack close, get the pan lined, and do not walk away.
- Move your oven rack so the top of the steak will sit about 4 to 6 inches from the broiler element. Do this before you preheat, not after.
- Turn the broiler to high and let it preheat for a full 10 minutes. This is the step people skip, and it’s the difference between browned and grey.
- Line a sheet pan with foil. This is your entire cleanup plan.
- Pull the steak out of the marinade, let the excess drip off, and lay it flat on the pan. Score the top in a shallow diamond pattern with a sharp knife — it helps it cook evenly and it looks like you tried.
- Broil 5 to 6 minutes. Flip. Broil another 5 to 6 minutes.
- Check the temperature in the thickest part with an instant-read thermometer. Pull it at 145°F for medium, then let it rest at least 3 minutes before you cut it.
Rest the steak on the cutting board for 10 minutes. Slice thin, against the grain.
A Word About Temperature, From the Dietitian in Me
USDA guidance for whole cuts of beef is 145°F followed by a 3-minute rest. That lands at a rosy medium, which is where I cook it — and it’s the number I’d give you if you asked me in a counseling session, especially if you’re feeding young kids, anyone pregnant, or anyone with a compromised immune system.
An instant-read thermometer costs about fifteen dollars and removes the guessing entirely. Time ranges are estimates; the thermometer is the answer.
Slice Against the Grain — This Matters More Than the Recipe
Look at the cooked steak and you’ll see long muscle fibers all running the same direction. Turn your knife so you’re cutting across those lines, not with them, and slice thin.
Cut it the wrong way and even a perfectly cooked flank steak chews like a shoelace. Cut it the right way and it’s tender. This one move does more for the final result than anything else on this page.
Same Dinner, Different Plate: What This Actually Looked Like
Here’s the part nobody puts in a recipe post. I made one dinner. Four kids ate four different versions of it, and I cooked exactly once. That’s the same dinner, different plate approach, and a broiled steak with separate sides is about the easiest place to use it.
On the counter: sliced steak, white rice, steamed broccoli, cucumbers, watermelon, and a plate of breadsticks from a tube. Everything separate. Nothing mixed.
Then:
• One kid built the full plate — steak, rice, broccoli — and ate all of it.
• One did steak and rice, skipped the green.
• One ate only steak. A pile of it, actually.
• And Michael looked at all of it and asked what was for dessert.
Nobody got a separate meal cooked for them. Nobody got negotiated with. The broccoli sat on the counter where it could be taken or not taken, which is exactly the amount of pressure I want at 6pm on a Tuesday.
The reason this works with a broiled steak specifically is that everything stays in components. There’s no casserole to deconstruct. Protein here, carb there, vegetable there, fruit there — every kid assembles the version they’re going to eat, and the adventurous one and the beef-only one are eating the same dinner.
If your evenings are cut in half by practice schedules, I broke down how to run this same system across two dinner shifts in my practice-night edition.

What to Serve With Broiled Flank Steak
Keep it in components and keep it boring on purpose. My rotation:
- Rice — white, microwaveable, no apologies
- Steamed or roasted broccoli
- Cucumber coins or baby carrots, raw, in a container on the table
- Watermelon or whatever fruit is already cut
- Breadsticks or rolls, because at least one child will build their entire dinner around bread
That’s a protein, a carbohydrate, a vegetable, and a fruit. That’s a balanced dinner. It does not need to be more complicated than that.
Leftovers Are the Real Reason I Make This
Sliced flank steak reheats better than most beef because it’s already thin. I deliberately cook more than we’ll eat.
- Steak and rice bowls the next night — my soy marinated steak and veggie bowls are built on exactly this
- Chopped into a lunch salad with whatever dressing is open
- Piled onto flatbread with peppers and cheese, Philly cheesesteak style
- Cold, standing at the fridge, at 3pm. Also a valid use.
MOVE OVER, MEAL PREP
I’m not spending Sunday afternoon prepping 14 perfectly portioned meals.
I’m just making more dinner.
If flank steak is on the menu tonight, I’m buying the bigger steak. Because while I’m already marinating it, broiling it and cleaning the pan… I might as well make enough to help myself out later in the week.
And THAT is my kind of meal prep.
One broiled flank steak can become:
🥩 Steak + potatoes + veggies tonight
🌮 Steak tacos another night
🥗 Steak bowls or salads for lunch
🧀 Steak quesadillas for the kids
🍝 A few steak bites alongside pasta + fruit
No completely different recipes.
No row of meal-prep containers.
No spending half of Sunday in the kitchen.
Just cook more of what you’re already cooking.
As a mom of four, I’ve learned that sometimes feeding my future self isn’t about being more organized.
It’s about making one less decision later.
Move over, meal prep. We’re cooking once and making it count. ❤️
Make Tonight’s Dinner Work for Tomorrow, Too
This is exactly the kind of dinner I want in my weeknight rotation. Four ingredients, 12 minutes under the broiler, and enough flexibility to feed my family tonight and make tomorrow a little easier.
If you have extra flank steak, don’t overthink it. Tuck it into quesadillas, add it to tacos or bowls, serve a few slices alongside your kids’ favorite sides, or eat it cold straight from the fridge while you’re packing lunches. (We’ve all been there.)
You don’t need a Sunday full of meal prep to make the week easier. Sometimes you just need to cook a little more of what you’re already making.
Dinner tonight. A head start tomorrow. Done. ❤️
