Step by step

Step one: precook the potatoes and onions

As we’ve discussed, the first step is to precook the potatoes. Just dice them up, place in them in a microwave-safe dish, and microwave on high for 5-7 minutes. You want them tender, but still holding their shape.

While that is happening, you can cook the onion. Add the butter to the skillet and cook the onion on medium- low for about 5 minutes, until translucent. Remove the onion to a small plate.

Step two: brown the potatoes

Turn the heat to medium-high and add the vegetable oil.

Place the diced potatoes in the skillet in a shallow layer. Don’t start stirring and flipping right away! Let them brown. Once one side starts to brown, you can flip. Add the seasonings and the onion back in, and keep turning until they are browned to your liking.

Step three: add the onions and seasoning

👩🏻‍🍳 Expert tips

Everyone loves home fries, but a lot can go wrong when making them at home. The most common culprits are undercooked potatoes, burnt onions, or just a total lack of flavor.

The first problem, undercooked potatoes, is easy to deal with. This recipe starts with pre-cooked potatoes. This might seem like it’s more work for you, but it’s definitely easier. When you start with the potatoes already cooked, all you have to think about once they move to the skillet is how browned you want them. You already know they are soft inside.

You must use both oils. Vegetable oil is the best for browning the home fries because it won’t smoke the way butter will. That means you can turn up the heat a little higher to brown them . But of course, butter has the most flavor. That’s why sautéing the onion in the butter works so well, because you remove it all before you fry the potatoes.

There are two ways to precook the potatoes, which both work just fine. You can bake them ahead of time, or dice them and microwave them in a shallow dish.


You can add just about anything to this recipe. Here are some ideas:

  • Crumbled, cooked bacon
  • Diced fresh jalapeños, added with the onion
  • Fresh herbs, especially chives
  • Garlic salt or fresh garlic
  • A pinch of cayenne pepper
  • Fresh green or red bell pepper (sauteed with the onions)
  • Cajun seasoning

What if I don’t have a cast-iron skillet?

You can use any heavy-bottomed pan. You might need a little more oil, depending on how sticky your pan is. (But cast iron is especially nice for being able to turn up the heat and getting nice browning on your food.)

Should I peel the potatoes?

It’s up to you! I don’t. But peeled potatoes are definitely prettier, if that matters to you.
