Ingredients Method Notes

Ingredients
  

Burger Base
  • 1 lb ground beef (80/20 or 85/15 depending on cooking method)
Mushroom Topping
  • 8 oz Baby Bella or Cremini mushrooms, sliced pre-cooked at home
  • 2 tbsp unsalted butter for cooking mushrooms
  • 1 tsp Worcestershire sauce
  • 1 clove garlic, minced
  • 1/4 tsp thyme optional
Assembly
  • 4 potato rolls
  • 4 slices Baby Swiss cheese deli sliced
  • 2 tbsp butter for toasting buns

Method
 

  1. At Home: Prepare the compound mushroom butter by mixing softened butter with Worcestershire sauce, minced garlic, and thyme. Roll into a log with parchment and chill.
  2. Cook sliced mushrooms in butter until browned and dry. Cool, then seal in a flat container or bag for camping.
  3. Form burger patties and freeze between parchment squares. Keep frozen until campsite.
  4. At Camp – Method A: Griddle or Skillet
    Preheat the surface until water sizzles. Place patty and smash flat. Sear for 1–2 minutes. Flip, top with mushrooms and cheese, then cover with steam dome and add a splash of water to melt cheese.
  5. Method B: Open Fire or Grill
    Grill patties over flame on foil or grill mat. Move to foil pan, add mushrooms and cheese, cover with foil and melt with residual heat.
  6. Method C: Reverse Foil Packet
    Sear patties first, then move to foil with cheese and mushrooms. Wrap and let rest near heat to finish cooking and melting.
  7. Toast buns in butter until golden to prevent sogginess. Assemble with desired toppings.

Notes

Bring extra parchment to separate patties. Store compound butter in a sealed container if not rolled. Use an upside-down skillet if you forget the dome. Check your cooler's temperature to stay below 40°F. Always toast buns for better texture.
For vegetarians, use marinated Portobello caps as a burger base.
Use a tin can to collect grease and keep wildlife away from camp.
