Ingredients List

This oven baked corned beef hash comes together with humble, flavorful ingredients you likely already have. The key is starting with good, starchy potatoes and well-seasoned corned beef.

• 1 ½ pounds russet potatoes, peeled and diced into ½-inch cubes (about 3 medium potatoes)
• 1 tablespoon olive oil
• 1 large yellow onion, finely diced
• 2 cups cooked corned beef, shredded or diced (about 10-12 ounces)
• 3 cloves garlic, minced
• 1 teaspoon smoked paprika
• ½ teaspoon dried thyme
• Salt and freshly ground black pepper, to taste
• 4 large eggs (optional, for serving)
• Chopped fresh parsley, for garnish

Smart Swaps & Notes:

• Potatoes: Yukon Golds are a great alternative for a creamier texture. For a twist, try my Corned Beef Hash with Sweet Potatoes.
• Corned Beef: Use leftover homemade corned beef or a good-quality deli version. In a pinch, thick-cut ham or even pastrami works wonderfully.
• Dairy-Free: The recipe is naturally dairy-free as written. For a cheesy version, check out my Cheesy Corned Beef Hash recipe.
• Spice Level: Add a pinch of red pepper flakes with the garlic if you like a little heat.

Timing

• Prep Time: 15 minutes
• Cook Time: 45-50 minutes
• Total Time: About 1 hour

This method is about 30% more hands-off than a traditional stovetop corned beef hash recipe, as the oven provides consistent, even heat for that perfect crispy finish.

Step-by-Step Instructions

Follow these simple steps for a foolproof, flavorful result every time.

1. Prep the Potatoes
Place your diced potatoes in a medium pot and cover with cold water. Add a generous pinch of salt. Bring to a boil, then reduce heat and simmer for 8-10 minutes, just until the potatoes are fork-tender but not falling apart. They should hold their shape. Drain well and set aside. Parboiling is the secret to creamy interiors in your final oven baked corned beef hash.

2. Sauté the Aromatics
While the potatoes cook, preheat your oven to 400°F (200°C). In a large, oven-safe skillet (cast iron is ideal), heat the olive oil over medium heat. Add the diced onion and cook, stirring occasionally, for 5-7 minutes until soft and translucent.

3. Build the Hash
Add the minced garlic, smoked paprika, and thyme to the skillet. Cook for just 30 seconds until fragrant. Stir in the cooked corned beef and the parboiled potatoes. Gently fold everything together, trying not to break up the potatoes too much. Season generously with salt and pepper. Let the mixture cook undisturbed for 3-4 minutes to develop a light crust on the bottom.

4. Bake to Perfection
Transfer the skillet to the preheated oven. Bake for 25-30 minutes, until the top is golden brown and irresistibly crunchy. No need to stir—this is where the magic happens!

5. Serve & Enjoy
Remove the skillet from the oven (careful, the handle is hot!). If desired, create four small wells in the hash and crack an egg into each. Return to the oven for 6-8 minutes for set whites with runny yolks. Garnish with fresh parsley. For more egg ideas, see my Corned Beef Hash & Eggs guide.

Equipment Needed

You don’t need any fancy gadgets for this oven baked corned beef hash recipe. Just a few basics:

• A large, oven-safe skillet (10-12 inch). A cast iron skillet is perfect for achieving maximum crispiness.
• A medium pot for boiling the potatoes.
• A sharp knife and cutting board.
• A wooden spoon or spatula for mixing.

Why You’ll Love This Recipe

• The Ultimate Crunchy Top: The oven creates a uniformly golden, crispy crust that’s impossible to achieve with stovetop cooking alone.
• Hands-Off Cooking: Once it’s in the oven, you’re free to set the table, make coffee, or simply relax.
• Meal Prep Hero: It reheats beautifully and tastes even better the next day, making it perfect for busy weeks.
• Incredibly Versatile: Serve it for breakfast, brunch, or dinner. It’s a complete, satisfying meal on its own.
• Simple Ingredients, Warm Memories: It transforms basic pantry staples into a deeply comforting and nostalgic dish.

Healthier Alternatives for the Recipe

This oven baked corned beef hash is easily adaptable to different dietary needs without sacrificing flavor.

• Lower Carb: Swap half the russet potatoes with diced turnips or rutabaga. They roast beautifully and offer a similar texture.
• Lower Sodium: Use low-sodium corned beef or substitute with roasted turkey breast. Be mindful of seasoning with salt.
• Extra Veggies: Stir in a cup of finely chopped bell peppers or mushrooms when sautéing the onions for added nutrients and flavor.
• Lighter Option: Use a light spray of avocado oil instead of olive oil, and opt for a leaner protein like shredded chicken or turkey.

Serving Suggestions

This hearty hash is a meal in itself, but it loves company. Here are a few of my favorite ways to serve it:

• The Classic Brunch: Top with a fried or poached egg and a side of buttered toast or English muffins. It’s a far more satisfying start to the day than simple beans on toast.
• With a Bright Side: A simple arugula salad with a lemon vinaigrette cuts through the richness perfectly.
• Dinner Time: Serve it alongside steamed green beans or roasted broccoli for a complete, cozy dinner.
• For a Crowd: Double the recipe and bake it in a 9x13 inch casserole dish. It’s fantastic for feeding a group.

Common Mistakes to Avoid

• Skipping the Potato Parboil: Adding raw diced potatoes will result in uneven cooking—crunchy outsides and hard, starchy centers. Parboiling ensures tender, fluffy potatoes throughout your oven baked corned beef hash.
• Overcrowding the Skillet: If your skillet is too small, the hash will steam instead of crisp. Use a large (10-12 inch) skillet for the best results.
• Stirring During Baking: Resist the urge to open the oven and stir! Let the heat work its magic to form that signature crunchy top.
• Underseasoning: Corned beef is salty, but the potatoes need love too. Taste the mixture before it goes in the oven and season well with black pepper and a little salt if needed.

Storing Tips for the Recipe

• Refrigerator: Cool completely, then store in an airtight container for up to 4 days. The flavors truly deepen overnight.
• Freezer: Portion the cooled hash into freezer-safe bags or containers. It will keep for up to 3 months. Thaw overnight in the fridge before reheating.
• Reheating: For the best texture, reheat in a skillet over medium heat with a tiny bit of oil until hot and crispy again. You can also use the oven at 350°F until warmed through. The microwave works in a pinch but will soften the crispy texture.

Conclusion

This oven baked corned beef hash is more than just a recipe; it’s a reliable kitchen friend. It’s the answer to “what’s for dinner?” on a tired Tuesday and the centerpiece of a leisurely Sunday brunch. It proves that comfort food doesn’t have to be complicated or time-consuming. With its irresistible crunchy top and savory, hearty flavor, it’s a dish that everyone at the table will love.
