In one of my previous lives, before I became a food blogger and a South Beach Dieter, I used to be president of my local teacher’s association, aka the teacher’s union. This was a demanding high-pressure job that I sometimes loved, sometimes hated, but one thing I did enjoy about the job was the chance to travel. I went all over the U.S., and it was in Miami Beach that I had my first experience with Cuban food.

I loved the way beef and pork were marinated in lime juice in the Cuban cuisine, so a few years ago I tried to re-create that flavor in this flank steak. Cuban Flank Steak is one of my most-used ways to cook beef on the grill.   If you’re grilling for a beef-loving Dad this weekend, I can promise this will be a hit!

(Flank steak is best when it’s not cooked above medium. I use my Polder Digital Meat Timer to check the temperature.)

Cuban Flank Steak
(Makes 4-6 servings, recipe created by Kalyn)

1 large piece of flank steak (this recipes makes enough marinade for 1-3 pounds of meat)

Marinade Ingredients:
1/3 cup fresh lime juice
1/4 cup olive oil
1 tsp. ground cumin
1 tsp. dried oregano
1 tsp. onion powder
1 tsp. garlic powder
1 T soy sauce (or coconut aminos for Paleo version)
1/2 tsp. ground chipotle chile powder (or use your favorite hot sauce)
2 tsp. lime zest (optional)


Combine marinade ingredients. Put flank steak into a ziploc bag and pour marinade in, seal bag, and marinate all day in refrigerator. (You can marinate up to 24 hours if desired.)

Take meat out of refrigerator and let it come to room temperature before grilling. Oil the grill with a paper towel dipped in olive or grapeseed oil, then preheat gas or charcoal barbecue grill to medium-high (you can only keep your hand there for a few seconds.)

Grill meat to desired doneness, approximately 4-5 minutes per side for rare to medium rare or 6 minutes for medium. I wouldn’t cook flank steak more than medium or it will be tough. Cooking time will depend on the thickness of your flank steak, the best way to judge the doneness is to use an instant-read meat thermometer, cooking to 140-145 for medium rare or 155-160 for medium. (The meat in the photo was cooked about 5 minutes per side.)

Remove meat from grill and let rest about 5 minutes. (You can cover with foil to keep it warm if needed.) Slice across the grain and serve hot, with slices of fresh lime to squeeze on the meat.

  1. OMG Kalyn, that looks DELICIOUS! We do a lot of grilled meats and I'm always looking for interesting new marinades. This one fits the bill!

  2. Would this work well for a FLAT IRON Steak??

  3. It wouldn't hurt to marinate flat iron steak in this marinade for a few hours, but flat iron doesn't really need to be marinated; it's much more tender than flank steak. Here is my favorite recipe for Flat Iron Steak.

  4. I love Cuban flavors and like to marinate beef, shrimp and even fish in the lime and cumin. Flank steak on the grill really is the best!
