This is the best steak marinade I've ever tried. No need for steak sauce when you have something this flavorful! The longer you marinate, the better flavor but I don't need to tell you that! Recipe and picture from Allrecipes.
1/3 cup soy sauce
1/2 cup olive oil
1/3 cup fresh lemon juice
1/4 cup Worcestershire sauce
1 1/2 tablespoons garlic powder
3 tablespoons dried basil
1 1/2 tablespoons dried parsley flakes
1 teaspoon fresh ground black pepper
1/4 teaspoon hot pepper sauce
1. Place all ingredients in blender. Blend on high speed for 30 seconds until thoroughly mixed.
2. Pour marinade over desired type of meat in large Ziploc bags or in a dish. Cover, and refrigerate for up to 8 hours. Cook meat as desired. Best on grill.
3. This is for 8 servings, which I used 8 steaks and it was enough marinade for that much meat.
