A quick and easy recipe for warm, comforting smash burger tacos packed in a thermos, perfect for hot school lunches and busy mornings.

Ingredients

Scale
  • 1 lb ground beef (80/20 lean-to-fat ratio recommended)
  • Salt and pepper to taste
  • 1/2 tsp garlic powder
  • 1/2 tsp onion powder
  • 1 cup shredded cheddar cheese (about 100 g)
  • 68 small flour tortillas (about 6-inch diameter)
  • 1 tbsp butter
  • Ketchup (optional)
  • Mustard (optional)
  • Pickles, sliced (optional)
  • Thermos (preheated with hot water before filling)

Instructions

  1. Preheat your cast-iron or non-stick skillet over medium-high heat for 3-4 minutes until very hot.
  2. In a mixing bowl, combine ground beef with salt, pepper, garlic powder, and onion powder. Mix gently but thoroughly without overworking the meat.
  3. Divide the beef into 6-8 equal balls (about 2 oz each). Do not flatten yet.
  4. Place a beef ball in the hot skillet and immediately press down firmly with a spatula to flatten into a thin patty about 1/4 inch thick. Hold the press for 15-20 seconds to get a good sear. Cook for 2 minutes without moving.
  5. Flip the patty carefully and immediately sprinkle about 2 tbsp shredded cheddar cheese on top. Cook for another 1-2 minutes until cheese melts and burger is cooked through.
  6. While patties cook, melt butter in a separate pan over medium heat. Warm tortillas one at a time for 20-30 seconds per side until soft and slightly golden.
  7. Assemble tacos by layering each tortilla with a cheesy smash burger patty. Add ketchup, mustard, and pickles if desired.
  8. Preheat the thermos by filling it with boiling water, closing the lid, and letting it sit for 5 minutes. Empty the water.
  9. Carefully place the assembled tacos inside the thermos, stacking gently, and seal tightly.
  10. Pack and enjoy. The thermos keeps the tacos warm until lunchtime.

Notes

Preheat the skillet well to get a crispy crust on the patties. Do not overwork the meat to keep patties tender. Toast tortillas with butter to prevent sogginess in the thermos. Assemble tacos just before packing for best freshness. Cook patties in batches if needed to maintain pan heat.
