The Story Behind This Classic Recipe
Hash has humble beginnings. It was born from a need to use up leftovers. Cooks would chop up yesterday’s meat and potatoes, fry them together, and create a new meal.
My grandma made it every Monday after a Sunday corned beef dinner. Nothing went to waste in her kitchen. The sizzle from her big black skillet is a sound I’ll never forget.
Adding caramelized onions was her special touch. She said the sweetness balanced the salty beef perfectly. That extra step makes all the difference. It turns simple ingredients into a memorable dish.

What Makes This the *Traditional* Way
This recipe sticks to the basics. We’re not adding trendy ingredients or complicated steps. The goal is deep, simple flavor from a few good components.
The real secret is patience. You can’t rush caramelized onions. They need low, slow heat to become sweet and golden. Rushing them just steams them.
We also cook the potatoes and beef separately at first. This gives everything a chance to get crispy. Then we bring it all together. It’s a classic technique that guarantees the best texture.
The Classic Ingredients (No Fancy Stuff!)
Here’s what you’ll need. Every item has a job to do, and together they create magic.
- 2 tablespoons unsalted butter
- 2 tablespoons vegetable oil
- 2 large yellow onions, thinly sliced
- 1 ½ pounds russet potatoes, peeled and diced into ½-inch cubes
- 1 pound cooked corned beef, chopped into bite-sized pieces
- 2 cloves garlic, minced
- 1 teaspoon fresh thyme leaves (or ½ teaspoon dried)
- Salt and freshly ground black pepper, to taste
- 4 large eggs (optional, for serving)
- Fresh parsley, chopped (for garnish)
How to Make It Just Like Grandma Did
Follow these steps for a perfect hash. Take your time and enjoy the process. Good food can’t be hurried.
- Caramelize the onions first. Melt 1 tablespoon of butter with 1 tablespoon of oil in your cast iron skillet over medium-low heat. Add the sliced onions and a pinch of salt. Cook, stirring now and then, for 25-30 minutes until they are deeply golden and sweet. Transfer them to a bowl.
- Cook the potatoes. Add the remaining oil to the skillet and turn the heat to medium. Add the diced potatoes in a single layer. Let them cook without stirring for 5-6 minutes to get a good crust. Then stir and cook for another 10-12 minutes until tender and browned all over. Season with salt and pepper, then move them to the bowl with the onions.
- Brown the corned beef. Add the last tablespoon of butter to the skillet. Add the chopped corned beef and cook for 4-5 minutes until it gets some crispy edges. Add the garlic and thyme and cook for one more minute until fragrant.
- Bring it all together. Return the potatoes and onions to the skillet with the beef. Gently mix everything. Press it down lightly with your spatula. Let it cook undisturbed for 4-5 minutes to form a delicious crust on the bottom.
- Serve it up. Make four little wells in the hash. Crack an egg into each well if you like. Cover the skillet and cook for 3-4 minutes until the egg whites are set. Garnish with fresh parsley and dig in.
My Tips for Perfecting This Classic
A couple of small things can make your hash even better. These are the tricks I’ve learned over the years.
First, use cold, cooked potatoes if you have them. They fry up even crispier. If you’re starting with raw, make sure to dry the diced potatoes well with a towel before frying.
Second, don’t stir the hash too much once you combine it. Let it sit and form that crispy crust on the bottom. That’s the best part! A good cast iron skillet is key for this.
How to Store and Enjoy Later
Leftover hash keeps well. Let it cool completely, then store it in an airtight container in the fridge for up to 3 days.
To reheat, warm it in a skillet over medium heat. This helps it get crispy again. The microwave will make it soft.
You can also freeze it for up to 2 months. Thaw it in the fridge overnight before reheating in a skillet. It makes for a quick and satisfying meal any day of the week.

Your Questions About This Classic Recipe
Here are answers to some common questions I get about this beloved dish.
Can I use canned corned beef?
You can, but the texture and flavor will be different. Leftover homemade or deli corned beef is best. It has more flavor and better texture for frying.
Canned beef can be a bit mushy. If you use it, pat it dry before adding it to the skillet. This helps it brown a little.
What kind of potato is best?
I always use russet potatoes. They get nice and fluffy on the inside and crispy on the outside. Yukon Golds are a good second choice.
They are waxier, so they hold their shape well. They won’t get quite as crispy, but they’ll still be delicious.
Do I have to use a cast iron skillet?
I really recommend it. Cast iron holds heat evenly and helps create that perfect, crispy crust. It’s a classic tool for a classic recipe.
If you don’t have one, use the heaviest skillet you own. Just make sure it’s oven-safe if you plan to finish the eggs under the broiler.
I hope this recipe finds its way to your table on a lazy weekend morning. There’s something so special about a meal that’s been loved for generations.
It’s simple, honest food that fills your belly and warms your heart. I think that’s the best kind of cooking there is.
