Ingredients
  

For the Steak
  • 1 kg rump steak (or sirloin) 1-2 cm thick
  • 10-15 g salt (1-1.5% of meat weight)
  • 1 tsp black pepper to taste
  • 4-6 tbsp butter (1-1.5 tbsp per steak)
For the Mashed Potatoes and Spinach
  • 500 g potatoes peeled
  • 500 g spinach fresh or frozen
  • 1 tsp salt or to taste

Equipment

  • 1 large frying pan or skillet
  • 1 meat tenderizer (hammer-style)
  • 4 plastic zip-top bag
  • 1 large pot (for boiling potatoes and spinach)
  • 1 potato masher or fork
  • 1 cutting board
  • 1 knife
  • 1 strainer

Method
 

1. Prepare the Steak
  1. Ask your butcher to slice the rump steak into 1-2 cm thick pieces.
  2. Season with salt, pepper, and olive oil. Mix well to coat each piece evenly.
  3. Place the steaks in a zip-top bag and refrigerate overnight.
2. Tenderize the Steak
  1. Remove the steaks from the fridge 30 minutes before cooking.
  2. Use a meat tenderizer to pound each steak until thin and larger in size.
3. Cook the Steak
  1. Preheat a large frying pan over medium-high heat.
  2. Cook each steak for 3-4 minutes per side until a crust forms and the steak is well-done.
4. Add Butter
  1. While the steaks are hot, place 1-1.5 tbsp butter on each piece.
  2. Let the steaks rest for 5 minutes to absorb the butter.
5. Make the Mashed Potatoes and Spinach
  1. Boil the potatoes in a large pot of salted water until tender.
  2. Add the spinach during the last 2-3 minutes of boiling.
  3. Drain the water and mash everything together using a masher or fork. Adjust salt to taste.
6. Serve
  1. Plate the buttery steaks with a side of mashed potatoes and spinach. Enjoy!

Notes

  • For best results, let the steaks rest with butter to maximize tenderness.
  • Don’t over-mash the potatoes and spinach—leave them slightly chunky for a rustic texture.
  • Use fresh spinach for brighter flavor or frozen spinach for convenience.
