Crispy Skillet Potatoes and Onions in 30 Minutes

These skillet potatoes and onions come out golden and crisp-edged on the outside, tender in the middle, and deeply savory from the browned butter. It is the kind of side dish that works next to a fried egg for breakfast or a roast chicken for dinner.

You only need a handful of ingredients and one heavy pan. The trick is letting the potatoes steam under a lid before you let them fry, so they cook through without burning.

What Makes These Potatoes a Weeknight Win

I love how unfussy this dish is. Slice, season, and let the pan do the work while you pull together the rest of the meal.

The best part is the contrast you get in the same bite: the soft onion slumps into the golden crevices of a potato slice, and the edges stay crisp. It tastes like the best diner-style home fries, but from your own stove.

Ingredients

• 2 lb Yukon Gold potatoes, scrubbed: their waxy texture holds its shape and crisps up beautifully
• 1 large yellow onion: sweet and mild, half-moons work best
• 2 tbsp unsalted butter: for richness
• 1 tbsp neutral oil: vegetable or canola, to keep the butter from burning
• ½ tsp kosher salt: start with this, adjust at the end
• ¼ tsp black pepper: freshly ground if you have it
• Small handful fresh parsley, chopped: optional, for a bright finish

Variations / Substitutions

• Swap the potato: red potatoes or fingerlings also work, no need to peel. Russets will be starchier and may break apart a bit.
• Add smoky heat: stir in ½ tsp smoked paprika or a pinch of cayenne when you season the potatoes.
• Go all olive oil: use 3 tbsp olive oil instead of butter and oil; the flavor changes but still gets crisp.
• Dairy-free: replace the butter with a plant butter or more oil.
• Toss in bacon: cook 3 strips of chopped bacon first, then use the rendered fat to fry the potatoes.

How to Make Skillet Potatoes and Onions

Step 1: Slice the Potatoes and Onions

Slice the potatoes into even rounds about ¼ inch thick. You want them all roughly the same thickness so they finish cooking at the same time. Halve the onion from root to tip, then cut it into thin half-moons.

The potato slices will look a bit like thick coins, and the onion half-moons should separate into nice long strands when you toss them in the pan later.

Step 2: Sear the Potatoes

Set a large 12-inch skillet over medium-high heat and add the 2 tbsp butter and 1 tbsp oil. Once the butter melts and the foam settles, carefully lay the potato slices in a single layer. Try not to crowd them. Sprinkle with the salt and pepper, then cover with a lid and cook for 5 minutes.

When you lift the lid, the bottom edges of the potatoes should be golden and starting to crisp. A little steam will curl up, and the slices will feel softer if you poke them with a spatula.

Step 3: Toss in the Onions

Scatter the onion half-moons right over the potatoes. Use a wide spatula to flip everything in big sections, keeping the onions mostly on top so they soften rather than burn. No lid this time. Cook for another 6 to 8 minutes, letting the onions wilt and turn translucent.

You will hear the sizzle settle into a steady, rhythmic sound as the moisture cooks off. The onions will shrink and start to pick up some golden edges too.

Step 4: Crisp Everything Up

Now push the heat up a notch to high. Spread the potato and onion mixture back into an even layer and cook for 3 to 4 minutes without moving it. Flip once more and give the other side another 2 to 3 minutes. The goal is crackling edges and deep golden spots all over.

The pan will smell nutty from the browning butter, and some smaller potato bits may get extra dark and crunchy. Those are the best parts.

Step 5: Finish with Fresh Herbs

Slide the potatoes onto a warm serving plate or just bring the skillet to the table. Scatter the chopped parsley on top while everything is still hot, and hit it with a little more salt if you like. Serve right away.

A Few Tips Before You Start

• Pick the right potato: Yukon Gold or red potatoes give you a creamy interior and a crisp shell. Stay away from baking potatoes here if you can.
• Do not skip the lid in the first stage. That short steam is what cooks the thick slices through without forcing you to parboil.
• The best pan is a well-seasoned cast iron skillet or a heavy stainless steel pan. Thin pans will cause uneven browning and burning.
• If you notice the pan getting too dark before the potatoes are tender, lower the heat slightly and add a splash of water, then pop the lid back on for a minute.

Cook times by potato thickness:

Storing Leftovers

• Refrigerate: cool completely and move to an airtight container. They will keep for up to 3 days.
• Reheating: warm them back up in a hot skillet with a tiny drizzle of oil. A microwave will soften the crispy edges, so a stovetop reheat is worth the extra minute.
• Serve cold: these lose their appeal cold, so I would always reheat.

What Goes Well With Skillet Potatoes and Onions

Serve them alongside a couple of sunny-side-up eggs for a hearty breakfast that soaks up the runny yolk. They also hold their own next to a seared steak, where the crispy potatoes contrast the tender meat. For a lighter dinner, pile them next to a lemony arugula salad and a piece of roast chicken, the brightness cuts the richness nicely.

Frequently Asked Questions

Can I make these ahead of time?

They are at their crispiest right out of the pan, but you can cook them fully, cool, and reheat in a hot skillet. Reheating brings back most of the crunch.

Do I need to peel the potatoes?

No, the thin skins on Yukon Gold or red potatoes add texture and flavor. Just scrub them well. If you prefer them peeled, that works too.

How do I get them extra crispy?

Make sure the pan is really hot before adding the potatoes, and do not crowd the skillet. Let them sit without stirring during the final few minutes to develop a deep crust.

Can I use sweet potatoes instead?

Yes, sweet potatoes work but they cook a bit faster and tend to caramelize more. Keep a close eye and reduce the cook time by a few minutes.

Ingredients Method Notes

Ingredients

  

• 2 lb Yukon Gold potatoes, scrubbed
• 1 large yellow onion
• 2 tbsp unsalted butter
• 1 tbsp neutral oil
• ½ tsp kosher salt
• ¼ tsp black pepper
• Small handful fresh parsley, chopped (optional)

Method

 

1. Slice the potatoes into even ¼-inch rounds. Halve the onion and slice into thin half-moons.
2. Melt the butter and oil in a 12-inch skillet over medium-high heat. Add the potatoes in a single layer, season with salt and pepper, cover, and cook for 5 minutes.
3. Scatter the onions over the potatoes, flip everything with a spatula, and cook uncovered for 6 to 8 minutes until the onions soften and turn golden.
4. Raise the heat to high, spread the mixture into an even layer, and cook undisturbed for 3 to 4 minutes. Flip once more and cook another 2 to 3 minutes until deeply golden and crispy.
5. Transfer to a serving plate, top with parsley, and serve hot.

Notes

Let the potatoes sit still during the final high-heat stage to build a crust. If the pan looks dry, add a small pat of butter. I like a little extra salt right before serving.
