Recipe Variations

Oil: Instead of using vegetable oil, you can use your favorite oil instead. Olive oil or avocado oil will work great for this recipe. Just make sure that the oil has a high smoke point. 

Seasonings:  The best part of this recipe is that you can easily change it up by using different seasonings like garlic salt or your favorite dried or fresh herbs. 

Spicy: Add a dash of cayenne pepper or red pepper flakes to add some heat to this simple dish.

Vegetables: If you want to add some additional vegetables you can add bell peppers, or even mushrooms to the potatoes while they are cooking.

Tips & Tricks

  • Russet potatoes or red potatoes are the best potatoes for frying, while waxy potatoes like Yukon Gold potatoes or new potatoes are not ideal. 
  • Try to slice the potatoes into thin, even slices for best results. A mandolin or a very sharp knife will work best for slicing. 
  • Don't skip the water soak, this helps to reduce the high starch content in the potatoes so that they can crisp up nicely. 
  • We usually fry our potatoes in a cast iron skillet for optimal crispiness but any type of heavy large skillet will also work. 
  • Instead of using oil and butter, you could also use bacon grease and butter for a little more flavor to these potatoes.
  • It's important to make sure you have a hot skillet before you add the potatoes and onions this will help them crisp up nicely.  
  • I prefer to use a sweet onion for this simple pan-fried potatoes recipe. However, you could also use a yellow onion instead.

FAQ

How to reheat this pan-fried potatoes and onions recipe? 

I prefer to reheat them in the oven on a baking sheet at 400 degrees until they are crispy and heated through. 

Why should I use half butter and half oil? 

If you use all butter, it will burn. The oil prevents the butter from browning too much. 

Why should you soak potatoes before frying?

Soaking the potatoes helps to get rid of some of the starch, which results in a crispier potato when cooked.
