Preparing the flank steak

Mixing the sauce ingredients
Now, let’s whip up the flavor-packed sauce!

Cooking time and temperature settings
For that melt-in-your-mouth tenderness, set your slow cooker to cook on HIGH for 2-3 hours or on LOW for 4-5 hours. The longer you cook, the deeper the flavors will become. Just be sure to plan ahead, especially if you’re cooking on low for a cozy weekend meal.
