  • 1 bottle Vegetable oil (16 ounces)
  • 1 boneless ribeye steak
  • ¼ cup chimichurri dry mix
  • ¼ cup red wine vinegar
  • ½ cup olive oil
  • 2 Tbsp Firemaster Secret Seasoning
  • Thinly sliced provolone cheese
  • 1 Tbsp Mayonnaise
  • 1 Russet potato
  • 1 French bread loaf


  1. **Prepare the Fire:** Build a fire at least 45 minutes before you start cooking to establish a hot bed of coals.
  2. **Prepare the Fries:** Slice your russet potato into thin julienne fries.
  3. **Heat the Oil:** Place your medium-sized cast iron skillet on your skillet rest and add vegetable oil. Heat the oil to 350 degrees Fahrenheit.
  4. **Season the Steak:** Coat your ribeye steak with Firemaster Secret Seasoning.
  5. **Cook the Fries:** Place the thinly sliced potatoes into the hot oil and cook for about 7-8 minutes, or until golden brown. Remove the fries from the oil and set aside.
  6. **Make the Chimichurri:** Combine chimichurri mix and red wine vinegar in a small bowl. Let the mix hydrate for about 5 minutes, then add olive oil and mix well.
  7. **Grill the Steak:** Place the seasoned steak on your Outpost Grill and cook to your desired temperature.
  8. **Rest the Steak:** Once cooked, remove the steak from the grill and let it rest for 5-10 minutes.
  9. **Toast the Bread:** While the steak rests, spread mayonnaise on both halves of the French bread loaf and toast them on the grill until golden brown.
  10. **Assemble the Sandwich:** Layer the bottom bread with provolone cheese, followed by the sliced ribeye, chimichurri mixture, and crispy fries. Top with the other half of the bread.
  11. **Serve and Enjoy:** Cut the sandwich in half, plate, and serve! Give this Firemaster Steak Frites Sandwich a try at your next gathering.
