I love using flank steak on the grill because it cooks quickly and is always tender, juicy, and full of flavor.

The spicy-sweet chili butter in this recipe is easy to whip up in a food processor. Dollop it on top of the steak right when it comes off the grill and it melts into a delectable sauce.

Is flank steak is a good cut of beef for grilling?

I love to grill flank steak. It is a great all-purpose steak that is perfect for grilling. It cooks quickly and is tender, juicy, and flavorful.

Grill it just to medium rare or medium, let it stand for several minutes after removing from the heat, and then slice it thinly across the grain.

Flank steak is usually best marinated before grilling, but the chili butter in this recipe adds so much flavor that marinating isn’t necessary. As a result, this recipe is super quick to prepare.

How long do you grill flank steak

Flank steak is relatively lean, so in order to keep it from drying out, don’t overcook it. I prefer flank steak cooked to medium-rare. If you like your steak a little more well done, cook it to medium.

For medium-rare, grill your flank steak for 4 to 5 minutes on the first side and 3 to 4 minutes on the second side. For medium cook it a minute or 2 longer on each side.

What ingredients do you need for this recipe?

This is a 5-ingredient recipe! All you need are:

  • Flank steak (or you can use skirt steak, flat-iron, or another good grilling steak)
  • Butter
  • Chile paste
  • Garlic
  • Honey

How do you make grilled flank steak with chili butter?

This is an incredibly simple recipe that takes only 20 minutes to make. Here are the steps:

  1. In a food processor, combine the butter, chile paste, garlic, honey, and some salt and process until well combined and smooth.
  2. Season the steak with salt and pepper.
  3. Grill the steak over medium-high heat, until medium-rare or medium.
  4. Remove the steak from the grill and dollop the chile butter on top. Let stand for 5 to 10 minutes.
  5. Slice the steak thinly across the grain and serve immediately.

What kind of chile paste do you use?

I like to use an Asian style chile paste, also called sambal oelek. I love this paste because it tastes just like ground up chiles.

You can also use the North African chile paste, harissa or sriracha.

If you don’t have any of those, substitute crushed hot red pepper flakes or ground cayenne pepper.

What do you serve with this?

I like to serve this steak as part of a summer barbecue spread with smoked baked beans and Watermelon Feta Salad, grilled veggies like asparagus or zucchini, or with a salad of greens like lettuce, baby spinach, or arugula.

Serve a crusty bread alongside for sopping up the crazy delicious melted butter/sauce. The chili butter would be amazing on cornbread!

My family also likes this steak chopped up and served as a filling for soft tacos or as a topping for tostadas. We add shredded lettuce and pico de gallo.

For another easy and impressive meat entree, try this Pan Seared Pork Tenderloin.

This easy recipe has only 5 ingredients and is made to serve 2 people. If you use a 1-pound flank steak, you'll have leftovers, but the leftovers are great for filling tacos or adding to a salad or sandwich. The recipe is excerpted from my book 5-Ingredient Cooking for Two.

  • 2 tablespoons unsalted butter at room temperature

  • Season the steak all over with the remaining salt and pepper.
  • Brush a grill or grill pan with olive oil and then heat it to medium-high heat.
  • Grill the steak for 4 to 5 minutes until grill marks appear on the bottom. Flip the steak over and cook to desired doneness, 3 to 4 minutes more for medium-rare.

  1. Hello! Beautiful recipe! Just wondering if I can sub out the chili paste for something else? Possibly red pepper flakes?

    thank you!

    • Sure, you could use red pepper flakes, ground chile like cayenne, or any type of hot sauce you like such as sriracha or harissa paste.
