Equipment

  • 12-inch cast iron skillet
  • Chef's Knife
  • Cutting Board
  • Wooden Spatula

Ingredients
  

Produce

  • 1 lb Yukon Gold potatoes (about 3 medium), cut into 1/2-inch cubes
  • 1 red bell pepper, diced
  • 1 green bell pepper, diced
  • 1 medium yellow onion, diced
  • 3 cloves garlic, minced

Meat

  • 1 lb ground beef (80/20)

Pantry & Spices

  • 2 tablespoons olive oil, divided
  • 1 tablespoon smoked paprika
  • 1 teaspoon cumin
  • 1/2 teaspoon chili powder
  • salt and black pepper, to taste
  • 1/4 cup beef broth (optional, for deglazing)

Optional Toppings

  • shredded cheddar cheese
  • sour cream
  • sliced green onions

Instructions
 

  • Cook the potatoes: Add the dried potato cubes to the hot skillet in a single layer. Let them cook undisturbed for 4 minutes — don't touch them, don't shake the pan. Then flip them and cook another 3-4 minutes, stirring once or twice. They should be browned and tender when pierced with a fork. Transfer to a plate.
  • Brown the beef: Add the ground beef to the same skillet. Break it up with your spatula and let it cook undisturbed for 2-3 minutes until the bottom is browned. Stir and continue cooking until no pink remains, about 3 more minutes. Transfer beef to a bowl, leaving about a tablespoon of rendered fat in the pan.
  • Sauté the aromatics: Reduce heat to medium. Add diced onion and cook for 2 minutes, scraping up browned bits from the bottom. Add garlic and cook for 30 seconds until fragrant.
  • Cook the peppers: Add both bell peppers and a pinch of salt. Sauté for 3-4 minutes until softened but still bright.
  • Return everything to the skillet: Add potatoes and beef back. Sprinkle with smoked paprika, cumin, chili powder, salt, and pepper. Stir and cook for 2 more minutes to toast the spices.
  • Deglaze (optional but game-changing): Pour in 1/4 cup beef broth or water and scrape up stuck bits. Let bubble for 1 minute until almost evaporated — the skillet should look glossy.
  • Top and serve: Remove from heat. Sprinkle with cheddar, green onions, or preferred toppings. Serve straight from the skillet.

Notes

Key tips for success: Dry potatoes thoroughly to avoid steam. Let them sit undisturbed for 4 minutes to develop a crust. Season at every stage — not just at the end — for layered flavor. If the dish feels flat, add a squeeze of lime or a dash of Worcestershire sauce at the end.
Swaps that work: For dairy-free, skip cheese and sour cream; add pickled jalapeños. For picky kids, swap bell peppers for diced carrots and peas. For a steak version, sear thin sirloin strips in batches and add back at the end.
Storage: Refrigerate in an airtight container for up to 4 days. Reheat in a skillet with a splash of broth. Freeze for up to 3 months — note that potatoes will soften, but flavor remains excellent.
