Heat olive oil in a large cast-iron skillet over medium-high heat. Once hot, add cubed potatoes in a single layer. Reduce heat to medium, cover the skillet loosely with foil or an ajar lid, and cook for 10 minutes, flipping potatoes with a thin metal spatula halfway through after 5 minutes.

Incorporate chopped onion and green bell pepper into the skillet. Lower heat to medium-low, cover again loosely, and cook for 5 minutes, turning the vegetables halfway through.

Stir in crushed garlic, table salt, smoked paprika, and black pepper. Reduce heat to low and cook uncovered for 3 minutes, stirring occasionally to ensure even seasoning and browning.

Remove skillet from heat. Sprinkle chopped cilantro, parsley, or sliced scallion over the potatoes if desired. Serve immediately to preserve crispiness.
