Preparing the ingredients

To make a delicious leftover corned beef hash, start by choosing quality ingredients, selecting fresh seasonal vegetables, and using proper cutting techniques for even cooking and blending of flavors.
Choosing your beef
For corned beef hash, I prefer using leftover corned beef. The beef should be tender and easy to shred. If you don’t have leftovers, store-bought corned beef works well too. Make sure to pick corned beef that’s juicy and flavorful. Check the seasoning of the corned beef and adjust the hash seasoning accordingly. Trimming excess fat can help create a more balanced dish, too.
Selecting seasonal vegetables
The right vegetables can enhance corned beef hash significantly. I like using russet potatoes for their starchy texture, which crisps up nicely. Onions add sweetness when sautéed, while carrots provide some extra crunch. Adding bell peppers and cabbage can introduce fantastic flavors and colors to the hash. Parsley and thyme are perfect for adding fresh, herbaceous notes. Opt for fresh vegetables to ensure the best taste and texture in your dish.
Cutting techniques for even cooking
Proper cutting ensures even cooking and enhances the texture of the hash. Dice the potatoes into small, uniform cubes so they cook evenly and get crisp. Chopping the onion finely helps it blend well with the other ingredients. Slice carrots thin for a quicker cooking time. For the corned beef, shred or dice it into small pieces. This allows it to mix well with the vegetables and achieve a harmonious, crispy texture. Using a sharp knife and cutting on a sturdy board can make the process quicker and more efficient.
By selecting the right ingredients and preparing them with care, you can create a delicious and satisfying corned beef hash.
Cooking and serving tips

To make the best corned beef hash, it’s crucial to achieve the perfect crisp on the potatoes and corned beef, and to dress and garnish the dish thoughtfully. Let’s dive into these essential tips.
Achieving the perfect crisp
To get that golden-brown, crispy texture on your potatoes and corned beef, start by choosing the right kind of potatoes. I prefer Russet potatoes because they crisp up nicely. Dice them into small cubes for even cooking.
Heat unsalted butter in a large skillet over medium-high heat. Butter not only adds flavor but also helps in achieving that perfect crisp. Add the potatoes and cook, stirring occasionally, until they are golden and crispy. This usually takes about 10 minutes.
Next, add diced leftover corned beef to the skillet. Make sure to shred it well so it disperses evenly. Continue cooking until the beef also gets a crispy edge. Season with kosher salt and black pepper.
For an added touch, crack a few eggs into the skillet and let them cook until the whites are set but the yolks remain runny. This adds another layer of texture and flavor.
Dressing and garnishing
Dressing up your corned beef hash with the right garnishes can make the dish look and taste fantastic. Try adding some freshly chopped bell peppers for a bit of crunch and a splash of color. They also offer extra Vitamin A and Vitamin C.
You can also stir in some caramelized onions for a sweet contrast to the saltiness of the corned beef. If you like a bit of spice, a dash of hot sauce really ramps up the flavor.
Fresh parsley or other fresh herbs like thyme can be sprinkled on top to add a touch of greenery and freshness. For added texture, top the hash with some crispy, fried hash browns or even some slices of soda bread on the side.
Serve the hash hot with a side of veggies to balance out the meal and enjoy a nutritious, protein-rich breakfast. The dish is not only delicious but also packed with essential nutrients like protein, fiber, calcium, and potassium. Happy cooking!
