Best Potatoes to Use

The type of potato greatly influences the final texture.

Russet potatoes are ideal if you love crispy edges because they contain more starch and less moisture.

Yukon Gold potatoes create a buttery texture with crisp edges and creamy centers.

Red potatoes hold their shape well and have a slightly waxy texture, making them excellent if you prefer firmer fried potatoes.

Fingerling potatoes provide a unique presentation and rich flavor.

For the crispiest results, Russet potatoes are the top choice.

Ingredients

4 large Russet potatoes, peeled or unpeeled according to preference

2 large yellow onions, sliced into thin half-moons

4 tablespoons vegetable oil

2 tablespoons butter

1 teaspoon salt

½ teaspoon freshly ground black pepper

1 teaspoon garlic powder

1 teaspoon onion powder

½ teaspoon paprika

½ teaspoon dried thyme

½ teaspoon dried rosemary, crushed

2 tablespoons chopped fresh parsley

Optional pinch of cayenne pepper

Optional freshly minced garlic

Optional grated Parmesan cheese

Optional chopped green onions

Equipment

Large cast iron skillet or heavy frying pan

Sharp knife

Cutting board

Large mixing bowl

Wooden spoon or spatula

Paper towels

Plate for serving

Preparing the Potatoes

Wash the potatoes thoroughly.

Peel them if desired, although leaving the skin on adds texture, nutrients, and rustic appearance.

Slice the potatoes into evenly sized pieces approximately one-quarter inch thick.

Uniform slices ensure even cooking.

Place the sliced potatoes into a large bowl filled with cold water.

Allow them to soak for at least 30 minutes.

This removes excess starch, which helps produce crispier potatoes.

After soaking, drain thoroughly.

Pat every slice completely dry using paper towels or a clean kitchen towel.

Removing moisture is one of the most important steps for achieving crispness.

Preparing the Onions

Slice the onions into thin half-moons.

Keep the slices relatively uniform so they cook evenly.

Yellow onions provide the perfect balance of sweetness and savory flavor, although white or sweet onions also work beautifully.

Seasoning

In a large bowl combine:

Salt

Black pepper

Garlic powder

Onion powder

Paprika

Thyme

Rosemary

Mix well before adding the potatoes later in the cooking process.

Cooking Instructions

Heat a large cast iron skillet over medium heat.

Allow the skillet several minutes to become fully hot before adding any oil.

Add the vegetable oil.

Swirl it around the pan until evenly coated.

Once shimmering, carefully add the potatoes in a single layer.

Avoid overcrowding the skillet.

If necessary, cook in batches.

Leave the potatoes undisturbed for about 5 to 7 minutes.

Resist the temptation to stir too early.

Allowing them to remain in contact with the hot skillet creates the golden crust.

Flip the potatoes using a spatula.

Cook another 5 to 6 minutes.

Continue turning occasionally until every side develops rich golden color.

Reduce the heat slightly if the potatoes begin browning too quickly.

When the potatoes are nearly tender, push them toward one side of the skillet.

Add the butter.

Once melted, add the sliced onions.

Cook the onions separately for several minutes before mixing them with the potatoes.

This encourages caramelization rather than steaming.

Stir occasionally while allowing the onions to slowly soften.

After about 8 to 10 minutes, the onions should become beautifully golden and sweet.

Mix the onions into the potatoes.

Sprinkle the seasoning mixture evenly over everything.

Continue cooking another 5 minutes.

Taste and adjust seasoning if necessary.

Just before serving, stir in fresh parsley.

Serve immediately while hot and crispy.

Tips for Extra Crispy Potatoes

Always dry the potatoes thoroughly after soaking.

Use a heavy cast iron skillet whenever possible.

Do not overcrowd the pan.

Allow the potatoes to sit undisturbed between turns.

Cook over medium heat instead of very high heat.

Add butter later rather than at the beginning to prevent burning.

Avoid covering the skillet during cooking because trapped steam softens the potatoes.

Delicious Variations

Add diced bell peppers during the last 10 minutes of cooking for additional sweetness and color.

Mix in sliced mushrooms for an earthy flavor.

Add smoked sausage for a complete one-pan meal.

Stir in crumbled cooked bacon for smoky richness.

Sprinkle shredded cheddar cheese over the hot potatoes until melted.

Add minced jalapeños for spicy heat.

Season with Cajun spices for Southern-style potatoes.

Mix in fresh dill for a brighter herbal finish.

Top with a fried egg for a hearty breakfast.

Finish with grated Parmesan cheese and cracked black pepper.

Serving Suggestions

Serve alongside scrambled eggs and toast for breakfast.

Pair with grilled steak or roasted chicken.

Serve with pork chops or baked fish.

Enjoy with burgers and sandwiches.

Use as a filling for breakfast burritos.

Serve beside meatloaf.

Add to a breakfast bowl with avocado and eggs.

Pair with grilled vegetables for a vegetarian meal.

Serve alongside barbecue dishes.

Enjoy with fresh salad for a lighter dinner.

Storage

Allow the potatoes to cool completely before refrigerating.

Store in an airtight container.

They will remain fresh for up to 4 days.

Reheating

For the best texture, reheat in a skillet over medium heat with a small amount of oil until crispy again.

They can also be reheated in an air fryer at 375°F (190°C) for 5 to 7 minutes.

Microwaving works in a pinch but produces softer potatoes.

Freezing

Although possible, freezing is not ideal because the potatoes may lose some of their crisp texture after thawing.

If freezing, cool completely and place in freezer-safe containers for up to 2 months.

Reheat directly from frozen in a skillet or oven.

Common Mistakes to Avoid

Skipping the soaking step.

Failing to dry the potatoes thoroughly.

Crowding too many potatoes into the pan.

Using heat that is too high.

Stirring constantly instead of allowing the potatoes to brown.

Adding onions too early, causing them to burn.

Under-seasoning the potatoes.

Cooking with a pan that is not fully preheated.
