I created this Flat Iron Steak Salad with Yogurt Dressing since I’m trying to eat in a smart and wholesome way.
I thought a flat iron steak recipe served with a delicious salad and a homemade yogurt dressing would make an easy weeknight dinner, too.
Flat iron steak is also called flank steak or top blade steak. I usually find it on sale.
Tenderizing the flat iron steak recipe
While the marinade does a good job on its own, I highly recommend using a blade meat tenderizer tool.
This tool pierces the flank steak all over, helping it to absorb the marinade better.
I have a Jaccard Supertendermatic 48-Blade Tenderizer and highly recommend that you buy yourself one, too.
It also prevents cheaper cuts of meat from shrinking and curling up.
Flat iron steak marinade
I used a store-bought barbeque sauce for my flat iron steak marinade. What could be easier?
Since I believe in using real ingredients, I look for sauces that are as basic as possible with no funky ingredients like high fructose corn syrup. So I recommend brands like Stubb's Original Bar-B-Q Sauce.
You’ll want to marinade the flat iron steak overnight to up to 24 hours before grilling.
Make sure to boil the heck out of any marinade you've used on raw meat. You want to kill any germs!
If you don't feel the flat iron steak marinade is safe, make an extra half batch to use for the dressing. Just reduce it over the stove, cool it down in the refrigerator, and then make your dressing just before you grill.
How to cook flat iron steak
The recommended doneness for flat iron steak is medium rare at around 135 F (60 C). Don’t forget to use your meat thermometer!
If it’s too rare, the steak is chewy. (I love rare steak, but not a too-tough-to-eat steak!) If you overcook the steak, it dries out and loses all its flavor.
I recommend grilling flat iron steaks over medium-high heat. Don't go as hot as possible unless you pick up a particularly thin cut that you can cook quickly.
When grilling, start with a quick sear before moving to a lower temperature to finish off to the desired doneness.
Remember to let the flat iron steak sit for a 5-10 minutes before slicing so the steak retains its juiciness. If you’re worried about it cooling down too much, tent it with aluminum foil and cover with a clean dish towel.
Putting the Flat Iron Steak Salad together
You can make this salad with just-off-the-grill steak. Or you can grill the steak and let it cool to room temperature – or even refrigerate it – and then carve it up.
I love steak salad both warm, room temperature and cold, so I’ll let you decide how you want to do the steps of grilling, salad preparation, and dressing preparation.
For example, you can make the salads and dressing ahead of time. Then later on just before mealtime, do the grilling, and so you’ll have a warm steak salad.
Or grill the flatiron steak and make the dressing the evening before, and put it all together for a Sunday brunch.
You can serve it with the dressing on it or on the side. (I like it on the side myself!)
If you’re making this for a romantic meal, you may want to all the prep ahead of time. Set the table, then do the grilling at the last minute.
More tips to make flat iron steak salad
I’ve started using minced garlic from a jar as a time-saving measure. (Now that I have a smaller kitchen, I don’t have the counter space to keep garlic and other produce in bowls as I did when I had a larger home.)
I find that 1/2 teaspoon minced garlic from a jar equals one fresh garlic clove, minced. I’ve read that some people find jar garlic is a little milder than fresh.
I don’t mind that it's milder and prefer the convenience. I also don’t have to deal with garlic cloves going bad or drying out.
In the dressing, you can use low fat or no fat Greek yogurt.

- Place on a tray or large plate (in case of accidental leaks) in the refrigerator overnight up to 24 hours before grilling.
- To grill, remove flat iron steak from baggie and reserve marinade.
- Grill flat iron steak until medium-rare – about 3 to 4 minutes on each side. Brush steak with extra marinade.

For the yogurt dressing:
- Take the reserved marinade and place in a small saucepan. Bring to a rolling boil over medium-high heat.
- Reduce heat to medium and boil for 10 minutes until reduced and thickened.
