Published: Mar 7, 2026 | By Ilyas Siaghy

Some of my favorite recipes come from those nights when the fridge is looking a little empty and dinner still needs to happen. This sausage potato leek Dijon mustard hash recipe came together on one of those evenings.

It had been a long day, and before I knew it, it was already close to dinner time. I opened the fridge hoping something would spark an idea. Inside were a few Yukon gold potatoes, a bunch of leeks that needed to be used, and some French sausage I’d picked up earlier in the week without much of a plan. Takeout definitely crossed my mind, but I wanted something warm and homemade. So I grabbed my cast iron skillet, diced the potatoes, sliced the sausage, and tossed everything into the pan with the leeks. Right at the end, I stirred in a spoonful of Dijon mustard, and suddenly the whole kitchen smelled incredible.

About twenty-five minutes later, we were gathered around the table scraping the last crispy bits straight from the skillet. Someone said, “You should make this again.”

And honestly… they weren’t wrong.

How to Make Sausage Potato Leek Dijon Mustard Hash

This leek sausage recipe comes together in one skillet with just a few straightforward steps. Follow along even if you’re brand new to cooking, you’ve got this.

Prep Your Ingredients (Step 1)

1. Wash and dice your potatoes into ½-inch cubes. You don’t need to peel them as the skin adds texture and nutrients. Just scrub them well.
2. Trim the leeks by cutting off the dark green tops and the root end. Slice lengthwise, then cut into half-moon slices about ¼-inch thick.
3. Place the sliced leeks in a bowl of cold water, swish them around to release any grit, then lift them out and pat dry. Leeks hide dirt between their layers — this step matters!
4. Mince the garlic and set aside.
5. If using sausage links, remove the casings by slitting them with a knife and squeezing the meat out, or simply slice into ½-inch coins if you prefer a chunkier texture.

Par-Cook the Potatoes (Step 2)

1. Heat 1 tablespoon of olive oil in a large cast iron skillet or heavy-bottomed pan over medium-high heat.
2. Add the diced potatoes in a single layer and don’t crowd them or they’ll steam instead of crisp. (If your pan isn’t big enough, cook in two batches.)
3. Season generously with salt, pepper, and smoked paprika.
4. Cook without stirring for 4–5 minutes until the bottoms are golden brown and starting to crisp.
5. Stir once, then cook another 4–5 minutes until the potatoes are fork-tender and nicely browned on multiple sides.
6. Remove potatoes from the skillet and set aside on a plate. They’ll go back in at the end.

👩‍🍳 Beginner Tip: The key to crispy potatoes is patience. Resist the urge to stir constantly. Let them sit and develop that golden crust, it’s worth the wait. This is the foundation of any great traditional potato hash recipe.

Brown the Sausage (Step 3)

1. In the same skillet (don’t wipe it out as those browned bits on the bottom are flavor gold), add the remaining tablespoon of olive oil over medium-high heat.
2. Add the sausage. If using crumbled meat, break it apart with a wooden spoon as it cooks. If using coins, lay them flat.
3. Cook for 4–5 minutes, stirring occasionally, until the sausage is browned and cooked through.
4. Use a slotted spoon to remove the sausage and set aside with the potatoes. Leave any drippings in the pan.

Soften the Leeks and Garlic (Step 4)

1. Reduce the heat to medium and add the butter to the skillet.
2. Add the sliced leeks and a pinch of salt.
3. Cook, stirring occasionally, for 5–6 minutes until the leeks are soft, silky, and just starting to turn golden at the edges.
4. Add the minced garlic and dried thyme. Cook for another 60 seconds until fragrant.
5. If using white wine or chicken broth, pour it in now and use your spoon to scrape up any browned bits stuck to the bottom of the pan. Let it bubble and reduce for about 1 minute. This step is called deglazing, and it’s how you capture all that concentrated flavor.

Bring It All Together With Dijon (Step 5)

1. Return the cooked potatoes and sausage to the skillet. Stir everything together gently.
2. Add the 2 tablespoons of Dijon mustard and toss to coat everything evenly. The mustard will melt into the hash, coating every piece in its tangy, savory magic.
3. Cook everything together for 2–3 more minutes, letting the flavors meld and the potatoes pick up any remaining flavor from the pan.
4. Taste and adjust seasoning: add more salt, pepper, or even a third tablespoon of Dijon if you love that punchy flavor.
5. Remove from heat, scatter fresh parsley over the top, and serve immediately.

✨ The Perfect Bite: You want a forkful with a bit of crispy potato, a chunk of sausage, a ribbon of soft leek, and that Dijon-coated coating all in one.

Tips, Variations & Substitutions

Pro Tips for the Best Hash

1. Don’t skip par-cooking the potatoes separately. Adding raw potatoes directly with the sausage leads to uneven cooking. This extra step makes the difference between soggy and crispy.
2. Use a cast iron skillet if you have one. It holds heat evenly and gives you that beautiful, restaurant-quality crust on the potatoes.
3. Season in layers. Add a little salt at each stage: potatoes, leeks, final taste for the most balanced flavor.
4. Dijon quality matters. Reach for a smooth, French-style Dijon like Maille or Grey Poupon for the most authentic flavor in this sausage potato leek Dijon mustard hash recipe.

Dietary Modifications

1. Dairy-free: Swap the butter for more olive oil or a plant-based butter.
2. Gluten-free: This recipe is naturally gluten-free, just double-check your sausage label.
3. Lower-carb: Replace half the potatoes with diced turnips or cauliflower florets.
4. Vegetarian: Use plant-based sausage and add a handful of white beans for protein.

Make It a Full Meal

• Brunch version: Top each serving with a fried or poached egg, the runny yolk acts like a sauce over the hash. Chef’s kiss.
• Cheesy version: Sprinkle Gruyère or sharp cheddar over the top in the last minute and let it melt.
• Add greens: Stir in baby spinach or kale right at the end for color and nutrients.

Storage & Reheating Instructions

This sausage and potato hash recipe is genuinely one of the best recipes for meal prep, the flavors actually get better as it sits.

Storing Leftovers

• Refrigerator: Store in an airtight container for up to 4 days.
• Freezer: Freeze in a freezer-safe container for up to 2 months. Note that the potatoes will soften slightly after freezing, but the flavor is still wonderful.

Reheating

• Stovetop (best method): Reheat in a skillet over medium heat with a tiny splash of oil or butter for 4–5 minutes, stirring occasionally. This brings back the crispiness.
• Microwave: Works in a pinch, heat in 60-second intervals, stirring between each, until warmed through.
• Oven: Spread on a baking sheet and reheat at 375°F (190°C) for about 10 minutes.

💡 Meal Prep Tip: Make a double batch on Sunday and reheat portions throughout the week with a fried egg on top for fast, protein-packed breakfasts or lunches. This is a true weeknight winner that keeps on giving.

Sausage Potato Leek Dijon Mustard Hash FAQs

What kind of sausage works best in a sausage potato leek Dijon mustard hash recipe?

French sausages like saucisse de Toulouse or French garlic sausage give you the most authentic flavor, but this is a wonderfully flexible recipe. Kielbasa, Italian sausage (mild or hot), bratwurst, or even a good chicken sausage all work beautifully. The key is choosing something with enough seasoning and fat to flavor the whole dish.

Can I use canned or pre-cooked potatoes?

You can, but fresh diced potatoes give you the best texture and crispiness. If you’re using canned potatoes, drain and dry them thoroughly, then add them directly to the skillet since they’re already cooked, just brown them for 3–4 minutes per side.

How do I keep my potatoes from getting mushy?

Three rules: dry your potatoes well before cooking, don’t crowd the pan, and let them sit undisturbed until they form a crust before stirring. Soggy hash usually comes from stirring too soon or cooking with too much moisture in the pan.

Is this recipe good for meal prep?

Absolutely, it’s one of the best! The hash holds up beautifully in the fridge for up to 4 days and reheats like a dream on the stovetop. Many people find it even tastier the next day once the flavors have had time to meld.

Can I make this recipe ahead of time for a crowd?

Yes! Cook the full recipe, then transfer it to a large oven-safe dish. Cover with foil and keep warm in a 275°F (135°C) oven for up to 45 minutes before serving. It’s a brilliant option for weekend brunch gatherings.

What do you serve with this hash?

This dish is hearty enough to stand alone, but it pairs beautifully with a simple green salad, crusty French bread, or a bowl of soup. For brunch, serve it alongside fresh fruit and mimosas. For dinner, a light vinaigrette salad balances the richness perfectly.

Can I add other vegetables to this hash recipe?

Absolutely! This is a great way to use up whatever’s in your veggie drawer. Bell peppers, mushrooms, zucchini, corn, or cherry tomatoes all work wonderfully. Add heartier vegetables (like bell peppers) with the leeks, and more delicate ones (like cherry tomatoes) in the last 2 minutes.
