Steak Tips with Caramelized Onions

Using Coca Cola is a commonly-used ingredient in steak marinades and it helps tenderize the beef. But – if you use a really good-quality cut of beef, it is not necessary and water can be used. (For our rib eye tips, we used water.)

Steak Tips with Caramelized Onions

INGREDIENTS
For the Marinade
  1. 1 cup ketchup
  2. ½ cup Coca-Cola or water (see note)
  3. ½ cup sugar
  4. ½ cup extra virgin olive oil
  5. ¼ cup red wine vinegar
  6. ½ cup Worcestershire sauce
  7. ½ cup A-1 Sauce
  8. 1½ tablespoons freshly ground black pepper

Other Ingredients
  1. 2 pounds sirloin or rib eye trimmed and cut into large cuts as big as 2 to 3 inches square
  2. 1 large onion, cut into thick strips vertically
  3. 1 tablespoon butter
  4. 1 tablespoon extra-virgin olive oil
  5. 1 teaspoon salt
  6. ¼ teaspoon freshly ground black pepper
  7. 1 teaspoon sugar

INSTRUCTIONS
  • In a medium sauce pan, place all marinade ingredients and bring to a boil, then reduce heat and gently simmer for 5 minutes. Remove from heat and cool completely.
  • Trim any gristle or large pieces of fat from beef. Cut into large pieces; about 2-3 inches square. Place cut beef in a zip lock bag. Pour cooled marinade over beef, seal and marinate 8-24 hours.
  • In a medium sauté pan over low heat melt butter in olive oil and place onions, salt, pepper and sugar and cook stirring occasionally for 30-40 minutes until onions are caramelized but not cooked down too much. Start cooking tips as the onions get close to finishing.
