Sliced potatoes and caramelized onions make an incredible, rustic combination. The natural starches of the potatoes crisp up golden brown, while slow-cooked onions melt into them with a rich, buttery sweetness that elevates a simple side dish into pure comfort food.
Here is a foolproof way to make a skillet of golden potatoes and deeply caramelized onions:
1. Essential Ingredients
-
The Potatoes: 3 to 4 medium Yukon Gold or Russet potatoes (peeled or unpeeled), sliced into even 1/4-inch rounds or half-moons. Yukon Golds hold their shape well while offering a buttery interior.
-
The Onions: 2 large yellow or sweet onions, sliced thinly into half-moons.
-
The Fats & Seasoning: 2 tablespoons butter and 2 tablespoons olive oil (the butter adds great flavor for caramelizing, while the oil keeps it from burning). Salt, freshly cracked black pepper, a pinch of garlic powder, and a few sprigs of fresh thyme or rosemary.
2. Step-by-Step Instructions
-
Caramelize the Onions First: Heat 1 tablespoon of butter and 1 tablespoon of olive oil in a large skillet over medium-low heat. Add the sliced onions and a pinch of salt. Cook slowly, stirring occasionally, for 20 to 30 minutes until they transform from crisp to a deep, golden-brown color and taste sweet. Remove them from the pan and set aside.
-
Par-Cook the Potatoes (Optional but Recommended): To ensure tender centers and a crispy crust, you can microwave your sliced potatoes for 3 to 4 minutes until slightly softened, or give them a quick 5-minute boil, then pat them completely dry.
-
Crisp the Potatoes: In the same skillet, add the remaining oil and butter over medium-high heat. Arrange the sliced potatoes in a single layer. Let them cook undisturbed for 4 to 5 minutes to develop a golden crust, then flip.
-
Combine and Melt Flavors: Once the potatoes are golden, tender, and cooked through, toss the caramelized onions back into the skillet with the potatoes. Let everything sizzle together for 2 to 3 minutes so the sweet onion flavors infuse into the potatoes.
-
Finish: Season with extra salt, black pepper, and fresh herbs if desired.
