This is an old family recipe
My grandmother, Myne, shared this easy flank steak recipe with me years ago in a “recipe book” that she wrote out by hand. In it, were all of the recipes I’d grown up with like her Northern Neck crab cakes, espresso fudge sauce and homemade peach blueberry pie. She gave me the book as a Christmas present one year and I return to it often for many of my favorites, including this bourbon steak marinade, which came from my Great Aunt Betty.
Ingredients For Bourbon Steak Marinade:
- Brown Sugar
- Bourbon (I use Jim Beam because it’s not too expensive and imparts a good flavor)
- Soy Sauce (can substitute Tamari)
- Olive Oil
- Garlic
- Thyme
- Crushed Red Pepper Flakes
- Black Pepper
Once you’ve mixed the marinade together, take a whiff! It smells amazing and the longer you let the steak marinate, soaking up those sweet, salty, umami flavors, the more intense they’ll be.
Cook the bourbon marinated grilled flank steak to your desired doneness. For medium rare that’s usually 5-8 minutes per side, depending on the size and thickness of your steak.
How to tell when the steak is done
If you’re a grilling aficionado, you know all about the “touch test” that will give you a good approximation of when you’ve achieved your desired doneness, but for a more accurate measure, use a good instant read thermometer. I recommend the Thermapen One {affiliate link} for its easy to read display and spot-on temperature readings. This one’s mine… but you can get your own…
- Rare: 120°-130°
- Medium Rare: 130°- 135°
- Medium: 135°-145°
- Medium Well: 145°-155°
- Well: 155°-160°
- Carbon: 165°+
Let It Rest
After removing the grilled marinated flank steak from the hot grill to a cutting board, let it rest.
I know it’s hard to resist, but if you start slicing right away, the juices within the meat will run out and you’ll lose much of the moisture that makes the steak taste tender, juicy and flavorful. About a five to six minute resting time is perfect for the juices to redistribute throughout the beef.
Didn’t I tell you this was an easy flank steak recipe? Feel free to use the bourbon steak marinade on other cuts as well. It would be great on a rib-eye, skirt steak, sirloin, porterhouse, London broil or New York strip.

Bourbon Marinated Grilled Flank Steak
INGREDIENTS:
FOR BOURBON STEAK MARINADE:
- ¼ cup brown sugar packed
- ¼ cup bourbon such as Jim Beam
- ¼ cup olive oil
- ½ cup soy sauce can substitute tamari
- 1 tablespoon thyme leaves chopped
- 3 large cloves garlic minced
- ½ teaspoon black pepper
- ¼ teaspoon red pepper flakes
FOR GRILLED STEAK
- 1½ pounds flank steak or london broil
DIRECTIONS:
MAKE THE BOURBON STEAK MARINADE
- In a small bowl or glass measuring cup, combine the brown sugar, bourbon, olive oil, soy sauce, thyme, garlic, pepper and red pepper flakes. Whisk to combine.
MARINATE
- Place the steak into a rimmed pan and cover the steak with the bourbon steak marinade. Wrap loosely with plastic wrap and refrigerate, flipping occasionally to ensure uniform marinating. Conversely, you can use a resealable plastic zip top bag, place the steak and marinade in the bag and squeeze out as much air as possible before sealing it. Flip the steak around a few times to coat it with the marinade.
- Place in the refrigerator for at least two hours or overnight, flipping and rotating the meat every few hours. (note: the longer the beef marinates, the more flavor will penetrate it.)
GRILLING EASY FLANK STEAK RECIPE:
- Heat barbecue to a medium high heat, about 450°.
- Remove steak from marinade and blot off the excess moisture with a paper towel.
- Place steak on hot grill. Cook for 5-6 minutes on the first side for medium rare. Flip the steak and cook an additional 5-6 minutes.
SERVING GRILLED MARINATED FLANK STEAK:
- Transfer steak to a cutting board and allow it to rest for 5 minutes so that the juices redistribute throughout the meat.
- Slice the flank steak thinly, against the grain and serve.

What at would you recommend for a rack of St Louis style ribs?
What about doing a thick cut Ribeye 1.23lbs by stovetop in a cast iron skillet?
Sounds good. Be sure to dry the steak well with a paper towel before putting it into a very hot skillet.
I make exactly as written, using low sodium soy sauce and my family LOVES this. Delicious!!
We love this too — and it’s so easy to make! Glad you and your family enjoyed it.
I love bourbon! Great idea for a marinade!
This needs to happen soon for dinner! Looks so delicious!
I saw this on Instagram and was immediately drooling – it looks and sounds so flavorful! Can’t wait to try it.
Just pinned this to my “Amazing Meat Recipes” board. That marinade seriously sounds and looks so over-the-top delicious! Beautiful photos too!
This sounds amazing! This marinade sounds so tasty.
Just did a variation of this with Jameson. Came out awesome! THANKS!
We tried this marinade on some round steak (London broil) yesterday and it turned out outstanding. Due to time constraints and not having the proper ingredients on hand, I used a Canadian whiskey, minced garlic, Tuscan style Italian seasoning and low sodium soy sauce. I can’t wait to try it with the real list of fresh herbs and bourbon. Thanks for the inspiration to try something different.
That sounds like a tasty marinade! London broil is one of my favorites!
Flank steak is one of my favorites. Thank you for a new marinade recipe. I will try!
This has been our go-to flank steak marinade for years.
The recipe starts out with “In a small bowl, mix the first 8 ingredients.” but there seem to be only 8 ingredients listed. Were there any ingredients missed?
Thanks for the catch! No ingredients missed, just can’t count!
Yum! This sounds really delicious! Definitely going to try this soon 🙂
