📝 About This Recipe

The Prego is a cornerstone of Portuguese tasca culture, traditionally enjoyed as a savory 'dessert' after a seafood feast or as a satisfying standalone lunch. This sandwich features thin, tenderized beef steaks deeply infused with garlic and wine, seared to perfection and served in a crusty Papo-seco roll. It is a rustic, soul-warming masterpiece that captures the essence of Lisbon's vibrant culinary scene in every juicy bite.

🥗 Ingredients

The Meat

  • 4 pieces Sirloin or Eye of Round steaks (cut thin, about 1/2 inch thick)
  • 6 pieces Garlic cloves (smashed and peeled)
  • 1/2 cup Dry white wine (Portuguese Vinho Verde is ideal)
  • 2 pieces Bay leaves (torn in half)
  • 1 teaspoon Sweet paprika
  • 1 teaspoon Kosher salt (to taste)
  • 1/2 teaspoon Black pepper (freshly cracked)

For Frying

  • 2 tablespoons Lard or Unsalted Butter (lard provides the most authentic flavor)
  • 1 tablespoon Extra virgin olive oil

The Bread and Assembly

  • 4 pieces Papo-seco rolls (Portuguese crusty rolls; sub with Ciabatta or Kaiser rolls)
  • 4 tablespoons Yellow mustard (traditional Portuguese style)
  • 1 teaspoon Piri-piri sauce (optional, for heat)
  • 2 tablespoons Garlic butter (softened, for spreading on bread)

👨‍🍳 Instructions

  1. 1

    Place the steaks between two sheets of plastic wrap and use a meat mallet to pound them until they are very thin, about 1/4 inch thick. This ensures they cook quickly and stay tender.

  2. 2

    In a shallow dish, season the steaks generously with salt, pepper, and paprika. Rub the smashed garlic cloves over both sides of the meat.

  3. 3

    Add the torn bay leaves and pour the white wine over the steaks. Let them marinate at room temperature for at least 15-20 minutes to absorb the flavors.

  4. 4

    Slice the rolls in half and lightly toast the cut sides under a broiler or in a dry pan until golden brown.

  5. 5

    Spread a thin layer of garlic butter on the toasted rolls and keep them warm.

  6. 6

    In a large heavy-bottomed skillet or cast-iron pan, heat the lard (or butter) and olive oil over medium-high heat until shimmering.

  7. 7

    Remove the steaks from the marinade, shaking off excess liquid, but keep the garlic cloves and the liquid aside.

  8. 8

    Place the steaks in the hot pan. Sear for about 1-2 minutes per side. You want a deep brown crust while keeping the inside juicy.

  9. 9

    Just before the steaks are done, toss the garlic cloves from the marinade into the pan to fry briefly until golden.

  10. 10

    Remove the steaks from the pan and place one directly into each prepared roll.

  11. 11

    Pour the remaining marinade liquid into the hot pan, scraping up all the brown bits (fond) from the bottom. Let it bubble and reduce for 30 seconds to create a quick 'jus'.

  12. 12

    Drizzle a spoonful of this pan sauce over the steak inside the bread.

  13. 13

    Top with a generous squeeze of yellow mustard and a few drops of piri-piri if you like a kick.

  14. 14

    Close the sandwich and press down slightly so the juices soak into the crumb of the bread. Serve immediately while piping hot.

💡 Chef's Tips

Always use thin-cut steaks; thick cuts will make the sandwich difficult to bite through. Pounding the meat is essential—it breaks down fibers and creates the signature 'Prego' texture. Don't skip the lard; it provides a richness that butter alone cannot replicate in this specific recipe. If you can't find Portuguese rolls, look for a bread that is crusty on the outside but very light and airy on the inside. For the best flavor, use a dry, acidic white wine like Vinho Verde or a crisp Sauvignon Blanc.

🍽️ Serving Suggestions

Serve with a side of hot, salty french fries (batatas fritas). Pair with a cold Portuguese lager like Sagres or Super Bock. A small side of mixed olives and pickled vegetables (variantes) cuts through the richness. Follow the local tradition and enjoy this as a follow-up to a bowl of Caldo Verde soup. Keep extra yellow mustard and piri-piri oil on the table for guests to customize their heat levels.
