The slow cooker does all the work while you layer potatoes and corned beef in perfect harmony, creating crispy edges and tender centers without a single pan in sight.
I developed this recipe after struggling to recreate my grandmother’s restaurant-style hash at home—until I discovered how the crock pot’s gentle heat achieves that ideal texture.
The beauty of this dish lies in its simplicity: just six core ingredients come together to deliver restaurant-quality results. You’ll start by browning corned beef and sausage for deep flavor, then layer them with potatoes in the crock pot.

What you’ll end up with is a dish that’s rich, satisfying, and packed with flavor—crispy at the edges, tender in the center, and infused with the smoky aroma of slow-cooked corned beef.
The layers of potato and meat create satisfying bites, while optional toppings like pickles, mustard, or green onions add fresh contrast. This is the kind of meal that feels indulgent yet comes together with minimal effort, perfect for feeding a crowd or meal prepping for the week.
Serve with crusty bread to soak up every last bit of that savory gravy, or pair it with a simple green salad for balance. The crock pot makes this dish foolproof, ensuring perfect results every time—no matter your cooking experience. Let’s get started on this hearty, flavorful masterpiece.
Ingredients for crock pot corned beef hash
Six simple ingredients transform into restaurant-style corned beef hash with smoky layers of flavor.
| Ingredient | Amount | Notes |
|---|---|---|
| Corned Beef Brisket 🥩 | 1 ½ lb | Pre-cooked, thickly sliced |
| Smoked Sausage 🌭 | ¾ lb | Kielbasa or smoked sausage |
| Russet Potatoes 🥔 | 3 lb | Medium, cut into 1-inch chunks |
| Yellow Onion 🧅 | 1 whole | Large, sliced into wedges |
| Garlic Cloves 🧄 | 6 cloves | Fresh, minced for flavor |
| Beef Broth 💧 | 1 ½ cups | Low-sodium preferred |
| Dijon Mustard 🍯 | 1 tbsp | For depth of flavor |
| Olive Oil 🫒 | 2 tbsp | For browning meat |
| Salt 🧂 | 1 tsp | Kosher or sea salt |
| Black Pepper 🌶️ | ½ tsp | Freshly ground |
| Bay Leaves 🍃 | 2 whole | For aromatic depth |
| Corned Beef Juices 💧 | ½ cup | From canned corned beef |
The corned beef is the star here—look for brisket cuts at the butcher counter or pre-sliced packages at Costco or Walmart. Smoked sausage adds that perfect smoky kick, and Kielbasa is my go-to because it’s easy to find and holds up well. Russet potatoes are non-negotiable for that crispy texture, but if you grab Yukon Golds, they’ll be extra creamy. The onions should be yellow—not red or white—they caramelize better and add sweetness that balances the saltiness. Fresh garlic is a must (the jarred stuff just doesn’t cut it), and I always buy extra because it’s so versatile.
No smoked sausage? Substitute with Italian sausage—just add a pinch of smoked paprika to mimic the flavor. Running low on corned beef? Use leftover roast beef or even deli ham in a pinch (though the flavor won’t be identical). For the broth, low-sodium is key—you don’t want to over-salt the whole dish. If you’re feeling fancy, add a splash of apple cider vinegar to the broth for brightness. The potatoes can be pre-cut and stored in water in the fridge for up to 2 days—just drain and pat dry before layering. And if you’re short on time, microwave the potatoes for 5 minutes before adding them to the crock pot to speed up cooking.
This dish reheats like a dream—3-4 minutes in the microwave or until piping hot. Store leftovers in the fridge for 4-5 days, but honestly, it’s even better the next day as the flavors meld. For meal prep, portion into containers with a side of crusty bread or pickles—trust me, it’s a game-changer. Freezes beautifully for up to 3 months, so double the batch and thank me later. The gravy at the bottom? Save it for mashed potatoes—it’s liquid gold.

Step-by-step instructions for crock pot corned beef hash
Here’s how to create hearty, layered comfort in minutes with minimal effort.
Brown the Meat for Maximum Flavor
Heat a large skillet over medium-high heat and add the 2 tablespoons olive oil. Add the 1.5 lb corned beef brisket and 0.75 lb smoked sausage, breaking the sausage into bite-sized pieces. Cook for 4-5 minutes until the meat is golden brown on all sides and the sausage begins to crisp.
Here’s the thing—browning the meat first develops deep, caramelized flavors that will infuse your entire dish. Don’t rush this step, but don’t let it burn either. You want visible color and some crispiness, not charred bits. Transfer the browned meat to your crock pot once it reaches this perfect stage.
Layer Potatoes and Aromatics Strategically
In a large bowl, combine the 3 lb russet potatoes (cut into 1-inch chunks), 1 whole yellow onion (sliced into wedges), and the 6 cloves minced garlic. Toss gently with the 1 tablespoon Dijon mustard and 1 teaspoon salt until everything is evenly coated. This step ensures each potato gets that signature mustard kick and won’t stick together.
Now for the layering magic: Spread half of the potato mixture in the bottom of your crock pot. Arrange the browned meat on top, then add the remaining potato mixture. Nestle the 2 whole bay leaves into the top layer. This arrangement creates perfect pockets for the flavors to meld during cooking.
Add Liquids and Season for Perfect Texture
Pour the 1.5 cups beef broth and 0.5 cup corned beef juices over the layered ingredients. Sprinkle with the 0.5 teaspoon black pepper. The juices will help create a rich, saucy finish while keeping the potatoes tender. Give everything a gentle stir to distribute the liquids evenly.
Here’s where it gets fun—the crock pot does all the work. Cover and cook on low heat for 6-7 hours, or until the potatoes are fork-tender with crispy edges. The slow cooking transforms the simple ingredients into a restaurant-quality hash with minimal effort on your part.
Check for Doneness and Final Touches
After the cooking time, remove the bay leaves and give the hash a taste test. The potatoes should be tender enough to pierce easily with a fork, but still hold their shape. If they’re not quite there, cook for another 30 minutes on low heat. You’ll know it’s perfect when the edges are slightly crispy and the flavors are fully developed.
For the final touch, give everything a good stir to distribute any accumulated juices at the bottom. The hash should be moist but not soupy, with each bite offering a perfect balance of tender potatoes, smoky sausage, and rich corned beef. Serve immediately while hot, with extra corned beef juices drizzled on top if desired.
Pro Tips For Making Crock Pot Corned Beef Hash
- CHOP POTATOES UNEVENLY: I learned this the hard way—cutting potatoes into perfect cubes makes them turn to mush in the crock pot. Instead, slice them into rough, uneven chunks: some thick, some thin, some even a little lumpy. The thicker pieces stay firm, while the thinner ones soften faster, giving you that perfect mix of textures.
- LAYER MEAT LOW: If you pile the corned beef brisket and smoked sausage on top of the potatoes, you’ll end up with a soggy bottom and a dry top. Instead, place the meat under half the potatoes in the crock pot. The heat will rise, cooking the meat evenly while the potatoes sit on top, soaking up all the juices without turning to glue.
- DRAIN SAUSAGE FIRST: Smoked sausage is juicy, and if you toss it straight into the crock pot, you’ll end up with a watery hash. Pat the sausages dry with paper towels, then drain them on a rack for 10 minutes before adding. This keeps the hash from turning into a stew and lets the flavors concentrate where they matter.
- BROWN THE MEAT: This isn’t the prettiest method, but it’s the tastiest. After dumping everything in the crock pot, take the raw corned beef brisket and smoked sausage out, sear them in a skillet over medium-high heat until they’re deeply browned on all sides. The caramelized crust adds depth that slow cooking alone can’t match—just don’t skip this if you want real flavor.
Serving suggestions for crock pot corned beef hash
Crispy Toppings
Finish your corned beef hash with toasted breadcrumbs or crushed potato chips for a satisfying crunch. I like using panko breadcrumbs toasted in 1 tablespoon butter until golden—just 2-3 minutes in a dry skillet over medium heat.
For extra flavor, mix in 1 teaspoon smoked paprika and ½ teaspoon garlic powder before toasting. 🌟
Another great option is crispy fried onions—sauté ½ cup thinly sliced yellow onions in 1 tablespoon olive oil for 5-6 minutes until caramelized. The sweetness balances the smoky hash beautifully. Sprinkle these on top right before serving to keep them crisp.
Classic Condiments
Set out yellow mustard and Dijon mustard for guests to customize their plates. I always include sweet pickle relish—just ¼ cup mixed with 1 teaspoon apple cider vinegar—because the tang cuts through the richness. For a spicy kick, add hot sauce or sriracha on the side. 🌶️
A dollop of sour cream or crème fraîche adds a creamy contrast, especially if you want to balance the saltiness. I like to mix 2 tablespoons sour cream with ½ teaspoon fresh dill and a pinch of salt for a bright garnish. Serve in small bowls for easy access.
Fresh Garnishes
Brighten the dish with chopped green onions or fresh parsley. I prefer green onions because their mild onion flavor complements the hash without overpowering it. Just 2-3 stalks sliced thinly will do—sprinkle them on top right before serving so they stay vibrant. 🥬
For a pop of color, add diced dill pickles or cornichons. Their acidity cuts through the richness, and the bright green or yellow adds visual appeal. I like to arrange them in a small bowl with a squeeze of lemon to enhance their flavor.
Bread Pairings
Serve with crusty sourdough bread or Irish soda bread to soak up the savory juices. I recommend a warm baguette sliced into thick pieces—toss it with garlic butter (mix 2 tablespoons softened butter with 1 minced garlic clove and ½ teaspoon parsley) before serving.
The buttery crust contrasts perfectly with the hearty hash. 🥖
For a lighter option, offer buttermilk biscuits or cornbread. The slight sweetness of cornbread pairs surprisingly well with the smoky flavors. I like to brush the tops with honey butter (melt 2 tablespoons butter with 1 tablespoon honey) for a touch of sweetness.

Frequently asked questions
Can I use pre-cooked corned beef from the deli counter?
Yes! Pre-sliced deli corned beef works perfectly—just measure out 1.5 pounds and skip the browning step. The key is to use the juices from the package (about ½ cup) to keep the hash moist. For extra flavor, sear the sausage separately before adding it to the crock pot.
How do I get crispy edges on the potatoes without burning them?
Layer the potatoes in a single even layer at the bottom of the crock pot, leaving ½ inch of space between chunks. Cook on low heat for 6-7 hours—the slow cooker creates steam that crisps the edges while keeping the centers tender. For extra crunch, broil for 2-3 minutes at the end if needed.
Can I make this in a slow cooker insert for my Instant Pot?
Use the same recipe and cook on the Sauté function for browning, then switch to the Slow Cook setting for 6 hours. The Instant Pot’s pressure won’t crisp the potatoes, but the flavors will still meld beautifully. For crispier edges, finish under the broiler after transferring to a baking dish.
What if I don’t have smoked sausage?
Swap it for Italian sausage (add ½ teaspoon smoked paprika) or bacon (cook until crispy). For a vegetarian option, use mushrooms and veggie sausage, but reduce the cooking time to 4-5 hours since they cook faster. The hash will still be delicious—just adjust the seasoning to taste.
How do I reheat leftovers without drying them out?
Sprinkle 1-2 tablespoons water or beef broth over the hash, cover with a damp paper towel, and reheat in the microwave for 2-3 minutes on 50% power. For stovetop reheating, cook on low heat with a splash of liquid for 5-7 minutes, stirring occasionally. The extra moisture prevents drying.
