Ingredients for Hash Recipe with Leftover Pork Roast
Transform last night’s pork into a golden-brown skillet masterpiece with these pantry staples.
| Ingredient | Amount | Notes |
|---|---|---|
| Leftover Pork Roast 🍖 | 2 cups | Diced into 1/2-inch pieces |
| Russet Potatoes 🥔 | 1 ½ lb | Peeled and diced small |
| Yellow Onion 🧅 | 1 whole | Medium, finely diced |
| Red Bell Pepper 🌶️ | 1 whole | Seeded and diced |
| Garlic Cloves 🧄 | 3 cloves | Minced finely |
| Fresh Rosemary 🌿 | 1 tbsp | Chopped, stems removed |
| Fresh Thyme Leaves 🍃 | 1 tsp | Stems removed |
| Dijon Mustard 🟡 | 1 tbsp | For depth of flavor |
| Worcestershire Sauce 💧 | 1 tbsp | Adds umami richness |
| Butter 🧈 | 3 tbsp | Unsalted, divided for cooking |
| Olive Oil 🫒 | 2 tbsp | Divided for cooking |
| Kosher Salt 🧂 | 1 tsp | Diamond Crystal preferred |
| Freshly Ground Black Pepper 🌶️ | ½ tsp | To taste |
| Smoked Paprika 🌶️ | ½ tsp | Optional, for added depth |
| Fresh Parsley 🌿 | 2 tbsp | Chopped, for garnish |
The pork is the foundation—use well-seasoned, moist leftover roast for best results. Russet potatoes are ideal for their high starch content, which delivers that coveted crisp exterior. For the herbs, fresh is non-negotiable; dried simply won’t provide the same aromatic punch. Source your potatoes from a reputable grocer like Whole Foods for consistent quality, and ensure the pork hasn’t been overly salted in its previous preparation.
No leftover pork? Cooked chicken or turkey work as substitutes, though the flavor profile will shift slightly. If avoiding alcohol, replace Worcestershire with coconut aminos. For a smokier note, swap regular paprika for smoked paprika. The red bell pepper can be omitted or replaced with green, though the sweetness of red complements the pork beautifully.
Store prepared hash in an airtight container in the refrigerator for up to 3 days. Reheat in a skillet over medium-low heat to restore crispness. For longer storage, freeze portions for up to 1 month—thaw overnight before reheating.

Step-by-Step Instructions for Hash With Leftover Pork Roast
This method transforms leftovers into a golden, crisp-edged skillet masterpiece with proper technique.
Step 1: Parcook the Potatoes for Even Cooking
Place the 1.5 lb Russet Potatoes in a pot of cold salted water. Bring to a boil over high heat and cook for exactly 5 minutes—they should be slightly tender but still hold their shape when pierced with a knife.
Drain immediately and spread on a baking sheet. This partial cooking ensures the cubes will crisp in the skillet rather than burn before cooking through. The starch on the surface will create that coveted golden crust when it hits the hot pan.
Step 2: Build Flavor Base with Aromatics
Heat 1 tbsp Olive Oil and 1 tbsp Butter in a large cast-iron skillet over medium heat. Add the 1 whole Yellow Onion and 1 whole Red Bell Pepper, cooking for 4-5 minutes until softened and just beginning to caramelize at the edges.
Add the 3 cloves Garlic Cloves, 1 tbsp Fresh Rosemary, and 1 tsp Fresh Thyme Leaves. Cook for 30 seconds until fragrant—this blooms the herbs’ essential oils. Stir in the 1 tbsp Dijon Mustard and 1 tbsp Worcestershire Sauce to create a rich, tangy foundation.
Step 3: Crisp the Potatoes and Pork
Increase heat to medium-high and add the parcooked potatoes to the skillet. Press them into the pan with a spatula and resist stirring for 3-4 minutes to develop a deep golden brown crust on one side.
Add the 2 cups Leftover Pork Roast and remaining 2 tbsp Butter and 1 tbsp Olive Oil. Season with 1 tsp Kosher Salt, 0.5 tsp Freshly Ground Black Pepper, and 0.5 tsp Smoked Paprika. Cook for 5-6 minutes, stirring occasionally, until potatoes are crisp on all sides and pork is heated through.
Step 4: Finish and Garnish
Taste and adjust seasoning if needed—the Kosher Salt should enhance but not overpower. The hash should have distinct crisp edges on the potatoes while maintaining moist, tender pork throughout.
Transfer to a serving platter and sprinkle with 2 tbsp Fresh Parsley. The herbs add a bright, fresh contrast to the rich, savory hash. Serve immediately while the crust is at its peak crispness.
Pro Tips For Making Hash Recipe With Leftover Pork Roast
- Crisp the Potatoes First: Par-cook the diced russets in oil for 8-10 minutes before adding other ingredients—this builds a golden crust that won’t turn mushy when mixed with the pork.
- Shred the Pork: Tear the leftover roast into thin strips instead of chopping; it distributes better and crisps up faster in the pan.
- Skip the Wet Pan: Pat the pork dry with a paper towel before it hits the skillet, or it’ll steam instead of sear—learned this the hard way with a soggy batch.
- Add Garlic Late: Toss in the minced garlic only in the last 2 minutes of cooking; earlier and it burns, leaving a bitter taste that ruins the hash.
Creative Variations of This Dish
Sweet Potato Twist
Swap Russet Potatoes for 1.5 lb sweet potatoes for a colorful, slightly sweet variation. The caramelization adds depth, and I love how the natural sugars pair with the savory pork. Parcook for 4 minutes to prevent mushiness. 💛
Breakfast Hash Style
Add 4 large eggs to the skillet during the final 2 minutes of cooking. Crack them over the hash, cover, and let the whites set while yolks stay runny. This is my go-to Sunday brunch for Tom and Lily.
Spicy Kick
Boost heat with ½ tsp cayenne or 1 diced jalapeño added with the aromatics. For a smoky touch, I use chipotle powder from New Seasons Market. Balance the heat with a dollop of sour cream when serving.
Vegetable-Packed
Add 1 cup diced zucchini or 1 cup frozen peas with the pork for extra veggies. Zucchini from my garden works especially well—just sauté it briefly first to remove excess moisture. This lightens the dish without sacrificing heartiness.
Cincinnati-Style
Honor my Ohio roots by topping the hash with shredded cheddar and broiling for 2 minutes until melted. Serve with a side of goetta for a true Cincinnati breakfast experience. 🌟

Frequently Asked Questions
Can I use a different type of potato?
Yes, Yukon Golds work well too. They have a slightly waxier texture than Russets but still crisp up nicely. Avoid red potatoes as they tend to turn mushy.
What if my pork is a bit dry?
Drizzle 2 tablespoons of chicken broth over the diced pork before adding it to the skillet. This adds moisture without making the hash soggy.
How do I get extra crispy potatoes?
Press the potatoes firmly into the skillet with a spatula and don’t stir for at least 4 minutes. Use medium-high heat and ensure the pan isn’t overcrowded.
Can I make this ahead of time?
Parcook the potatoes and chop all ingredients the night before. Store separately in the fridge and cook in the morning for fresh results.
