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.
In a food processor, combine the butter, chile paste, honey, garlic, 1/4 teaspoon of the salt, and 1/4 teaspoon of the pepper. Process until smooth.
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.
Remove the steak from the grill, transferring it to a cutting board. Dollop the chile butter on top and let rest for at least 5 minutes.
Slice the steak thinly across the grain and serve immediately, garnished with parsley if using.
Notes
1. You can substitute salted butter for the unsalted butter. Simply leave out the 1/4 teaspoon of salt in the butter mixture.
