Oven Fried Potatoes and Onions combines a favorite dish from my childhood with a classic French potato dish called Pommes Anna (Potatoes Anna).

This Fried Potatoes and Onions recipe is my own hybrid mix of the two. And, we absolutely love it!

Even better, you can make Fried Potatoes and Onions into a main dish by cracking eggs on top at the end of cooking time, to add protein and lusciousness to your meal.

What to Serve with Fried Potatoes and Onions

And if you would like to add bread to your meal, you can’t go wrong with my homemade biscuits or soda bread.

Fresh fruit, fruit salad or any of your favorite green vegetables are also perfect sides. My air fryer green beans would be fantastic!

The Ingredients

  • Russet Potatoes (I think Yukon Gold, Idaho Potatoes and Red Potatoes would work, as well.)
  • Red Onion
  • Butter (I used salted, but either should be fine.)
  • Homemade All Purpose Seasoning (I prefer this homemade blend, but if you have a favorite use that. Just be aware of the salt content. My homemade is low salt, so if yours isn’t, you may not need additional salt.)
  • Salt
Ingredients for Fried Potatoes and Onions on a Concrete Counter top:  Clear bowl of peeled and sliced Russet Potatoes, stick of softened butter, 1/2 cup of minced red onion and small white bowl with All Purpose Seasoning and Salt in it.

Why Use a 12″ Cast Iron Skillet?

I chose the 12″ skillet, so that there would be a larger surface area of crispy potatoes, in my Fried Potatoes and Onions.

You could use a smaller skillet, but the layers of potatoes would be thicker and increase the cooking time. For me, time is always at a premium near dinner. I like the method that gets my Oven Fried Potatoes and Onions on the table most quickly.

Also, I use my smaller, 10″, cast iron skillet as a weight on top of the potatoes as they cook.

I only have 1 cast iron skillet. What can I substitute as the top weight?

A heavy glass pie plate with dry beans or pie weights would be a good option. Or even a non-cast iron (but oven safe) skillet that can be filled with something like dry beans or pie weights. You just want something that will press down on the potatoes and help the maximum amount of potato surfaces to come in contact with the bottom of your cast iron skillet. This will help crisp up your Oven Fried Potatoes and Onions.

FAQ

Can I use a 10″ cast iron skillet instead of a 12″?

Yes. You will have more layers than I did in the 12″ skillet, so your Fried Potatoes and Onions may take longer to cook all the way through. Leave the weight on your 10″ skillet for 25 minutes, instead of 20. Then remove the weight and foil to finish cooking. It may take up to an additional 15 to 25 minutes, in addition to the time listed in the recipe, because of your thicker layers.

Can I substitute a different variety of potatoes?

Absolutely! You can make your Fried Potatoes and Onions with Russet potatoes, Yukon Gold potatoes, Idaho Potatoes or Red Potatoes. My favorites are Russets (the starch browns easily) and Yukon Golds.

How can I tell if my Oven Fried Potatoes are Done?

The simplest way to tell is to look for the crispy, golden brown top. After that, pierce the center of the potato layers with a fork. If the fork slides through easily to the bottom layer, the potatoes are done. This is called “fork tender”.

How to Make Fried Potatoes and Onions

The Prep

  1. Preheat the oven to 425° on the convection setting.  (If you don’t have convection, that’s fine.  Just set it to 425° and expect that it may take an additional 5 to 15 minutes to cook the Oven Fried Potatoes and Onions all the way through, depending on your specific oven.)
  2. Peel and slice the russet potatoes (or Yukon Golds) into 1/8″ thick slices. You can use a good, sharp knife.  But, I prefer this mandoline [affiliate link] for cutting uniform slices that cook evenly.  (You can check out my Amazon shop for more of my favorite kitchen tools.) If you don’t have a mandoline just be sure to keep your slices the same thickness and not thicker than 1/8″.

  1. Use 2 Tablespoons of the softened butter to grease the bottom and sides of the 12″ cast iron skillet, you will cook the Fried Potatoes and Onions in.
  2. Reserve 1 tablespoon of butter from what remains.  Set it aside for later.
  3. Melt the last 5 Tablespoons of butter in the microwave and stir in the All Purpose Seasoning and salt.  Set aside.

Layering the Potatoes, Onions and Butter Sauce

  1. Place sliced potatoes into the bottom of the 12″ cast iron skillet in a single layer.  I started in the center of the skillet and worked out for this first layer.  One slice in the center and then working outward in a circular pattern. Only add enough slices to cover the bottom with a slight overlap on each potato slice.
  2. With a pastry brush, brush seasoned melted butter over that first layer.
  3. Sprinkle half of the minced onions over the brushed first layer.
  4. Add a second layer of potatoes.  I started on the edge of the skillet and worked to the center for the 2nd layer.

  1. Wind the 2nd layer back to the center and then, with the pastry brush, brush seasoned melted butter over the second layer.
  2. Sprinkle the last half of the onions over this brushed layer.
  3. Add the third layer of potato slices for the Fried Onions and Potatoes.  I don’t usually have enough for a full layer so I arrange them in a single layer beginning at the center of the skillet and working out as far as it will go. I don’t usually overlap the top layer.
  4. Use the rest of the melted butter to brush the last layer.

  1. Tear a sheet of foil just large enough to cover the top of your skillet.
  2. Use the reserved softened butter to grease one side of the foil.
  3. Press the foil, buttered side down, over the potatoes in the skillet.
  4. Add a second smaller (oven safe) skillet (or a heavy pie plate with weights) on top of the foil to weight down the potatoes.

Baking and Serving

  1. Bake for 20 minutes.
  2. Remove the top skillet and the foil and continue baking for 12 to 25 minutes, until potatoes are golden brown and crispy on top and fork tender all the way through.  In my oven that only took about 12 minutes, but timing will vary from oven to oven.
  3. Remove from the oven and serve.

Make Fried Potatoes and Onions a Main Dish

One of the most affordable and delicious suppers I remember growing up was fried potatoes with eggs cooked on top.

Once your Fried Potatoes and Onions are done, you can enjoy the same homey and comforting main dish by simply removing the potatoes from the oven.

Raw eggs cracked over the top of Fried Potatoes and Onions, ready to go back to the oven for 3 to 4 minutes baking time.

Immediately crack the number of eggs you need for those you are serving over the top of the finished Fried Potatoes and Onions.

Place the skillet back into the 425° oven until the eggs reach their desired doneness.

It took between 3 and 4 minutes for my egg whites to be firmly set and the yolk to still be runny.

If you like hard yolks on your eggs, leave them in a little bit longer.

  • 1/2 cup butter, softened
  • 1 teaspoon homemade All Purpose Seasoning
  • 1/2 to 1 teaspoon salt, to taste

Instructions

  1. Preheat the oven to 425° on the convection setting.  (If you don’t have convection, that’s fine.  Just set it to 425° and expect that it may take an additional 5 to 15 minutes to cook the Oven Fried Potatoes and Onions all the way through, depending on your specific oven.)
  2. Peel and slice the russet potatoes (or Yukon Golds) into 1/8″ thick slices. You can use a good, sharp knife.  But, I prefer a mandoline for uniform slices that cook evenly.  If you don’t have a mandoline just be sure to keep your slices the same thickness and not thicker than 1/8″.
  3. Use 2 Tablespoons of the softened butter to grease the bottom and sides of your 12″ cast iron skillet.
  4. Reserve 1 tablespoon of butter from what remains.  Set it aside for later.
  5. Melt the last 5 Tablespoons of butter in the microwave and stir in the All Purpose Seasoning and salt.  Set aside.
  6. Place sliced potatoes into the bottom of the 12″ cast iron skillet in a single layer.  I started in the center of the skillet and worked out for this first layer.  Only add enough slices to cover the bottom with a slight overlap on each potato slice.
  7. With a pastry brush, brush seasoned melted butter over that first layer.
  8. Sprinkle half of the minced onions over the brushed first layer.
  9. Add a second layer of potatoes.  I started on the edge of the skillet and worked to the center for this layer.
  10. Again, with the pastry brush, brush seasoned melted butter over the second layer.
  11. Evenly sprinkle the remaining onions over the second layer that’s been brushed with butter.
  12. Add the third layer of potato slices.  I don’t usually have enough for a full layer so I arrange them in a single layer at the center of the skillet.
  13. Use the rest of the melted butter to brush the last layer.
  14. Tear a sheet of foil just large enough to cover the top of your skillet.
  15. Use the reserved softened butter to grease one side of the foil.
  16. Press the foil, buttered side down, over the potatoes in the skillet.
  17. Add a second smaller (oven-safe) skillet (or a heavy pie plate with weights) on top of the foil to weigh down the potatoes.
  18. Bake for 20 minutes.
  19. Remove the top skillet and the foil and continue baking for 12 to 25 minutes, until potatoes are golden brown and crispy on top and fork tender all the way through.  In my oven that only took about 12 minutes, but timing will vary from oven to oven.   And depend on the size of skillet you used, as well as the thickness of your potato slices.  It may take anywhere from 12 to 25 minutes to finish cooking.
  20. Remove your finished Fried Potatoes and Onions from the oven and serve.

Notes

Egg Topped Oven Fried Potatoes and Onions Option

After removing the finished potatoes from the oven, break raw eggs over the top.  (Use as many as needed for the group you’re serving.)  Place the skillet back in the 425° oven and bake until the eggs reach the desired doneness.  3 to 4 minutes was about perfect for a firm white and runny yolk in my oven.  Leave them longer for a hard yolk.

  1. I must’ve had 5 or 6 layers of potatoes in my cast iron Dutch oven. It was fine. I just went for the maximum cook time. Not as crispy as I’d like, but they taste great. Got to use up some old gold potatoes in the process, too. I’m definitely keeping this recipe and will be making it as a breakfast staple! Thanks for an easy, delicious keeper!
