Can you make corned beef hash ahead of time?

Yes, you can prepare the corned beef hash component of the casserole a day or two in advance. Store it in an airtight container in the refrigerator until you're ready to assemble and bake the casserole.

What goes well with corned beef hash?

Corned beef hash pairs well with eggs (fried, poached, or scrambled), toast, hollandaise sauce, roasted vegetables, or a side of baked beans. In a casserole, it often includes eggs, cheese, and sometimes bread or potatoes.

How long does corned beef hash last in the fridge?

Cooked corned beef hash will last for 3-4 days in the refrigerator when stored properly in an airtight container.

How do you keep corned beef hash from being dry?

To prevent dryness, ensure the hash has enough moisture from the potatoes, corned beef fat, and potentially a touch of broth or butter. Don't overcook it during the initial preparation or when baking the casserole. A layer of cheese on top of the casserole can also help retain moisture.

What is the best way to reheat corned beef hash?

The best ways to reheat corned beef hash are in a skillet over medium heat, stirring occasionally, until heated through; or in the microwave, covered, in short intervals until warmed through. For casserole leftovers, bake covered in a preheated oven at 350°F (175°C) until heated through.

Can you freeze corned beef hash breakfast casserole?

Yes, you can freeze a corned beef hash breakfast casserole, though the texture of the potatoes and eggs may change slightly. Wrap it tightly in plastic wrap and then aluminum foil, or store it in an airtight freezer-safe container. Thaw it overnight in the refrigerator before reheating.

Instructions

Preheat oven to 375°F. Grease a 9×13 inch baking dish.
In a large skillet, heat oil over medium heat. Add diced onion and bell pepper. Cook for 5-7 minutes until softened.
In a large bowl, combine the sautéed veggies, chopped corned beef, and thawed hash browns. Mix well and transfer to the prepared baking dish, spreading evenly.
In the same bowl, whisk together eggs, milk, sour cream, garlic powder, smoked paprika, and black pepper until smooth.
Pour the egg mixture evenly over the corned beef and potato base in the dish.
Sprinkle 1 1/2 cups of the shredded cheddar cheese over the top.
Bake for 40-45 minutes, or until the center is set and the top is golden brown. Sprinkle with the remaining 1/2 cup of cheese during the last 5 minutes of baking.
Let the casserole rest for 10 minutes before slicing. Garnish with fresh parsley or chives and serve.

Notes

Thaw hash browns completely to avoid a soggy casserole. Letting the bake rest for 10 minutes after cooking ensures clean slices. Reheats beautifully for meal prep.
