  • Traeger Grill heated to at least 375°
  • Large cast iron skillet
  • Wooden spoon or whisk
  • Potato masher
  • Cheese grater


  • 1 pound steak tips
  • 2 tbsp butter
  • 1 large yellow onion, diced
  • 2 carrots, diced
  • 2 ribs celery, diced
  • 1 red bell pepper, chopped
  • 1 cup frozen peas
  • 1 clove of garlic, pressed
  • 2 tbsp tomato paste
  • 1/2 cup red wine
  • 1 cup beef broth
  • 2 tbsp flour
  • salt, pepper and thyme to taste
  • 1 block Cabot Horseradish Cheddar, shredded
  • 1/2 block Cabot Colby Jack cheese, shredded
  • 1 pound yellow potatoes, boiled, mashed and seasoned to taste


  • Preheat Traeger Grill to at least 375°. Place cast iron pan in grill while it heats.
  • While the grill heats, pat dry the beef pieces with a paper towel and lightly season.
  • When the pan is very hot, cook the beef in batches until browned on all sides. Transfer to a bowl and cook remaining beef.
  • Add a bit of butter to the empty pan and cook the onion, carrot and celery until crisp-tender.
  • Stir in the remaining butter to melt, then whisk in the flour to create a roux. Cook until well combined and browned.
  • Stir in beef broth and wine. Then add tomato paste and garlic. Stir vigorously to combine.
  • Add the par-cooked beef back to the pan and add the frozen peas. Stir to combine and then close the grill lid, allowing to simmer for about 15 minutes until slightly thickened.
  • When slightly thickened, bring pan inside and top with prepared mashed potatoes (remember to add 1/2 the cheese to the potatoes). Spread evenly and top with remaining cheese.
  • Return pan to grill and cook for 20 minutes until golden on top and bubbling.
  • Carefully remove from grill, allow to sit for 5 minutes, and serve.
