Introduction

Corned beef hash is a nostalgic dish that brings comfort and flavor to the table, especially when adapted into a creamy, cheesy au gratin. The slow cooker method infuses the ingredients with rich flavors while allowing you to attend to other kitchen tasks.

This recipe transforms traditional corned beef hash into a delightful au gratin, making it perfect for family dinners or as a hearty brunch option. With tender potatoes, savory corned beef, and a gooey cheese topping, this dish is satisfying and deeply flavorful.

Using a slow cooker not only simplifies the cooking process but also ensures that the hash is moist and tender. As it cooks, the ingredients meld together beautifully, resulting in a dish that warms the heart and fills the belly.

Ingredients

2 cups diced cooked corned beef
Corned beef is the star of the dish, providing a meaty, savory flavor that pairs wonderfully with the potatoes. Using cooked corned beef allows for immediate infusion of flavor.
4 cups diced potatoes
Potatoes serve as the carbohydrate base, lending structure and absorbency to the dish. Choosing starchy potatoes helps achieve a creamy texture.
1 medium onion, finely chopped
Onion adds a savory depth and sweetness as it caramelizes during cooking, enhancing the overall flavor profile of the dish.
3 cups shredded sharp cheddar cheese
Cheddar offers a rich, tangy flavor that melts beautifully to create a golden crust on top of the hash, elevating the dish to au gratin perfection.
1 cup milk
Milk adds creaminess and binds the ingredients, creating a smooth mixture. It helps integrate the flavors and provides the necessary moisture for slow cooking.
1 tablespoon Dijon mustard
Dijon mustard introduces a subtle tanginess that brightens the dish, complementing the richness of the corned beef and cheese.
2 teaspoons garlic powder
Garlic powder infuses the dish with a mellow garlic flavor, enhancing the savory notes without the sharpness of fresh garlic.
Salt and pepper, to taste
Seasoning is crucial to balance the flavors. Too little salt can make the dish bland, while a bit of pepper adds a nice kick.

Directions & Preparation

Step 1: Prepare the slow cooker

Start by greasing the inside of your slow cooker with non-stick spray or a bit of oil. This prevents sticking and makes for an easier cleanup later. It also helps in achieving a nice, golden exterior on the cheese topping.

Step 2: Combine corned beef, potatoes, and onion

In a large bowl, mix the diced corned beef, potatoes, and chopped onion. This combination not only creates the foundational layers of flavor, but also ensures even distribution of the ingredients throughout the cooking process.

Step 3: Make the cheese mixture

In another bowl, combine the milk, Dijon mustard, garlic powder, and half of the cheddar cheese. This mixture adds richness and flavor to the dish, and the cheese helps form that coveted au gratin crust as it melts.

Step 4: Layer the ingredients in the slow cooker

Start layering with half of the potato mixture, followed by the cheese mixture, and then the remaining potatoes on top. This layering technique helps in even cooking and allows flavors to meld beautifully at different levels.

Step 5: Season and cook

Season the final layer with salt and pepper before covering the slow cooker. Cooking on low for 6-8 hours allows the flavors to develop and the potatoes to become tender, while preventing the dish from becoming mushy.

Step 6: Add remaining cheese and finish cooking

About 30 minutes before serving, sprinkle the remaining cheddar on top. This forms a melty, golden crust that is the hallmark of an au gratin, adding an irresistible textural contrast.

Step 7: Serve and enjoy

Once cooked, use a spoon to serve portions, ensuring everyone gets a bite of the cheesy goodness and corned beef. This dish is best enjoyed fresh but can be kept warm for a short while.

Creating the Perfect Layering Technique

Layering your ingredients strategically is key to ensuring even cooking and flavor distribution in this Slow Cooker Corned Beef Hash Au Gratin. By interspersing potatoes and the cheesy mixture, you allow the flavors to meld beautifully, creating distinct pockets of taste throughout the dish. This technique also guarantees that each serving is balanced with both potato and corned beef.

The Role of Cheese in Au Gratin Dishes

Cheese plays a pivotal role in transforming a simple dish into an indulgent experience. In this recipe, sharp cheddar is ideal due to its melting properties and bold flavor, which elevate the entire meal. As it bakes, the cheese forms a bubbly and golden crust, providing a delightful textural contrast to the tender fillings beneath.

Variations to Add Your Personal Touch

One of the joys of this Slow Cooker Corned Beef Hash Au Gratin is its versatility. You can easily swap in other ingredients such as sautéed bell peppers, or different types of cheese like Gruyère or Monterey Jack for varied flavor profiles. Experimenting with herbs such as fresh thyme or parsley can also add a fresh twist, making this dish authentically yours.
