Cast Iron Skillet Potatoes Recipe Ingredients

Ingredients

  • Russet potatoes
  • White onion – a yellow or red onion could also be used in place of the white onion.
  • Butter – depending on your salt preference, feel free to use salted or unsalted butter in this recipe.
  • Garlic – fresh cloves of garlic are always preferred for the best flavor!
  • Steak seasoning – click the link for my easy, popular steak seasoning recipe, or purchase pre-mixed Montreal steak seasoning on the spice aisle at the grocery store.
  • Fresh thyme – if you don’t have fresh, you can substitute in dried thyme.
  • Fresh rosemary – same as the thyme, if you don’t have fresh, you can use dried rosemary in this recipe.

Instructions

  1. Prepare the potatoes and onion. Slicing the vegetables with a mandoline is the easiest way to get uniform pieces. If you don’t have a mandoline, thinly slice the potatoes and onions with a sharp knife on a large cutting board.
  2. Coat the skillet. Melt butter in a 12 inch cast iron skillet over medium heat.
  3. Make the seasoning. Measure the steak seasoning, thyme and rosemary into a small bowl and stir to combine.
  4. Layer the ingredients. Arrange a layer of potatoes, slightly overlapping, on to the melted butter. Add onions and sprinkle the seasonings and one clove of crushed garlic over the potatoes. Repeat until the pan is filled, about 5 layers.
  5. Top with butter. Place cubes of butter over the top.
  6. Bake. Place the potatoes in a preheated 375°F oven for 40-45 minutes.

Frequently asked questions

  • How do you prevent food from sticking to a cast iron skillet? If your skillet is not seasoned, sticking could happen more easily. Prevent this by coating the pan with butter or oil before adding the food.
  • Is it necessary to boil potatoes before roasting? No, it is not. Simply slice, season and bake for perfectly tender insides and crispy outsides.
  • Can you bake cast iron in the oven? You certainly can. This makes it a convenient tool for recipes that go between the stove and oven such as these rustic potatoes, steaks or casseroles.
  • Can you use another type of skillet? Yes, if you don’t have a skillet, you can use another type of skillet. Just make sure the skillet is oven-safe up to 375°F.
