Introduction & Inspiration
Corned beef hash is a classic dish, and one I often associate with hearty breakfasts and diner-style comfort food. This recipe, attributed to Chef John (a popular and reliable culinary source), promised a flavorful and well-textured version. I was eager to try his take on this diner staple.
My inspiration came from a desire to create a satisfying and flavorful meal using leftover corned beef (a perfect way to use up leftovers after St. Patrick’s Day!), or even freshly cooked corned beef. I wanted a recipe that would be relatively straightforward, yet would deliver that perfect combination of crispy potatoes, savory corned beef, and flavorful additions.
My goal was to find a recipe that would be both approachable for home cooks and yield a truly delicious and satisfying corned beef hash. This Chef John recipe seemed to fit the bill perfectly: clear instructions, common ingredients, and a focus on achieving that ideal crispy texture.
This is a perfect recipe for a brunch.
Nostalgic Appeal
Corned beef hash holds a strong nostalgic appeal for many. It’s a dish often associated with diners, breakfast joints, and hearty, no-frills meals. It evokes memories of comforting breakfasts, family gatherings, and simple, satisfying food.
The combination of potatoes, corned beef, and onions (in this case, green onions) is a classic and familiar one, reminiscent of many traditional hash recipes.
The act of cooking everything together in a skillet, creating a crispy crust on the bottom, is a cooking technique that connects us to a long history of one-pan meals and rustic, home-style cooking.
And the overall experience of enjoying a warm, savory, and slightly crispy plate of corned beef hash, perhaps with a fried egg on top, is a timeless pleasure that transcends generations.
Homemade Focus

You’re taking cooked ingredients and transforming them into a new and delicious dish, adding fresh vegetables and seasonings to create a flavorful and satisfying meal.
I appreciate recipes that offer creative ways to use leftovers, and this one certainly does. It’s a resourceful and delicious way to give new life to cooked corned beef.
The addition of fresh green onions and garlic adds a vibrant flavor and aroma that elevates the dish beyond simple leftovers.
And the technique of cooking the hash in a skillet, allowing a crust to form on the bottom, is a key element that adds texture and enhances the overall homemade feel. It’s a simple yet effective way to create a truly satisfying dish.
Flavor Goal
The primary flavor goal of this Corned Beef Hash is a savory, salty, and slightly tangy combination of tender corned beef, crispy potatoes, and flavorful green onions, with a hint of garlic and a touch of heat from the black pepper. The salsa adds an unexpected but welcome twist.
The cooked corned beef provides the dominant savory and salty flavor, offering a rich, meaty base for the hash.

The green onions add a fresh, slightly pungent flavor and a pop of color.
The garlic contributes a subtle aromatic note that enhances the other flavors.
The butter adds richness and helps create a crispy crust on the bottom of the hash.

The overall effect is a flavorful and satisfying hash that’s both comforting and surprisingly complex.

List of Ingredients with Measurements
Here’s the complete list of ingredients, with precise measurements:
- 1 ½ pounds potatoes, peeled and quartered
- 1 ½ pounds cooked corned beef, finely chopped
- 1 bunch green onions, chopped
- salt and ground black pepper to taste
- 2 cloves garlic, crushed
- 1 tablespoon butter
- ¼ cup roasted tomato salsa
These quantities are perfect for 4 servings.
Gather all ingredients before starting.

Step-by-Step Instructions
Let’s break down the process into easy-to-follow steps.
Step 1: Cook Potatoes. Place the peeled and quartered potatoes in a large pot and cover with salted water. Bring to a boil. Reduce heat to medium-low and simmer until almost tender but still firm, about 15 minutes. Drain and finely chop the potatoes.
Step 2: Cook Corned Beef. Cook the finely chopped corned beef in a large cast iron or nonstick skillet over medium heat until the fat begins to render.
Step 3: Add Aromatics. Stir the chopped green onions, salt, and pepper into the beef. Add the crushed garlic and butter. Cook and stir until the butter is melted and the garlic is fragrant, 1 to 2 minutes.
Step 4: Add Potatoes and Salsa. Stir in the finely chopped potatoes, roasted tomato salsa, and a pinch of salt into the beef mixture.
Step 5: Form and Cook Hash. Pat the mixture down in the skillet with a spatula and divide the hash into 4 sections. Cook, without stirring, until a crust forms on the bottom, about 5 minutes.
Step 6: Flip and Cook. Flip the sections and cook until a crust forms on the bottom, about 5 minutes more.
Step 7: Repeat and Serve. Repeat the cooking and flipping process, flipping every 5 minutes, until the hash stays together and has a golden crust, 10 to 15 minutes.
These instructions are very clear.

Troubleshooting
Let’s address some potential issues, and how to solve them:
Problem: My hash is sticking to the skillet. Solution: Make sure you’re using a well-seasoned cast iron skillet or a nonstick skillet. Also, make sure the skillet is hot enough before adding the ingredients, and don’t try to move the hash around too much before a crust has formed.
Problem: My hash is too dry. Solution: You can add a little more butter or oil to the skillet.
Problem: My hash is too greasy. Solution: You can drain off some of the excess fat from the corned beef before adding the other ingredients.
Problem: My hash is bland. Solution: add more spices.
These solutions are helpful.
Tips and Variations
This recipe is very easy to adapt.
Tip: For a spicier hash, add a pinch of red pepper flakes or a dash of hot sauce.
Variation: Add other vegetables to the hash, such as diced bell peppers, onions, or mushrooms.
Tip: If you don’t have roasted tomato salsa, you can use regular salsa or even a little bit of ketchup or tomato paste.
Variation: Add a fried egg on top of each serving of hash for a classic diner-style meal.
Tip: Use leftover mashed potatoes instead of boiling and chopping fresh potatoes.
Variation: Add shredded cheese, such as cheddar or Monterey Jack, to the hash during the last few minutes of cooking.
