Start by peeling and cubing the russet potatoes. Aim for uniform pieces to ensure even cooking. Next, thinly slice the onions and mince the garlic. Setup is crucial in this recipe; it makes cooking smoother.
In a large skillet, heat the olive oil over medium heat. Add the sliced onions and sauté them until they turn soft and caramelized. This process might take about 10 to 15 minutes, so don't rush. Stir occasionally to ensure they don't burn; you want a lovely golden-brown color.
Once the onions have caramelized, add the minced garlic and cook for another minute until fragrant. Then, toss in the cubed potatoes. Stir everything together, ensuring the potatoes get coated in the buttery onion mixture.
Now, it's time to season. Sprinkle salt, freshly ground white pepper, smoked paprika, and crushed red pepper flakes over the mixture. Give it a good toss and make sure everything is well combined. Cover the skillet and let the potatoes cook for about 20 to 25 minutes. Stir occasionally to avoid sticking and allow for even cooking.
When the potatoes are tender and have a beautiful crisp on the outside, remove them from heat. Stir in the freshly chopped parsley for a touch of color and freshness.
