Ingredients for jason's deli irish potato soup copycat
Simple ingredients that transform into restaurant-quality Irish potato soup at home.
| Ingredient | Amount | Notes |
|---|---|---|
| Yukon Gold Potatoes 🥔 | 3 lbs | Peeled, cut into 1-inch cubes |
| Heavy Cream 🥛 | 1 cup | Full-fat for best texture |
| Whole Milk 🥛 | 1 cup | For creaminess without heaviness |
| Chicken Broth 💧 | 6 cups | Low-sodium preferred |
| Yellow Onion 🧅 | 1 whole | Medium size, chopped |
| Garlic Cloves 🧄 | 4 cloves | Peeled, lightly crushed |
| Fresh Thyme 🌿 | ¼ cup | Leaves only, chopped |
| Bay Leaves 🍃 | 2 whole | Remove before serving |
| Worcestershire Sauce 🍶 | 1 tbsp | For umami depth |
| Salt 🧂 | 1 ½ tsp | Kosher or sea salt |
| Black Pepper 🌶️ | ½ tsp | Freshly ground preferred |
| Butter 🧈 | 4 tbsp | Unsalted, cubed |
| Fresh Parsley 🌿 | ⅛ cup | Chopped, for garnish |
| Dried Thyme 🌿 | ½ tsp | Substitute if fresh unavailable |
The potatoes are the star—Yukon Golds are ideal for their buttery texture and creamy finish. Grab a 3-pound bag from the grocery store or farmers market, but don't skimp on quality. The broth matters too: low-sodium chicken broth keeps the flavor balanced (no need to add extra salt later). For the herbs, fresh thyme is best (I always grab a bunch and use half here, saving the rest for other dishes), but dried works in a pinch. The Worcestershire sauce might be in the international aisle—Lea & Perrins is the classic choice.
No fresh thyme? Dried at half the amount works fine. Short on heavy cream? Half-and-half plus a splash of milk gives similar richness. The butter should be cold-cubed—don't melt it ahead of time, or it'll clump in the soup. For extra depth, add a pinch of nutmeg (not listed, but trust me on this). The onion and garlic can be swapped for shallots if you're feeling fancy—just use the same amount. And if you're making this ahead, skip the parsley garnish until serving so it stays fresh.
This soup tastes even better the next day as flavors meld. Keeps 5 days in the fridge, freezes for 3 months. I always double the batch—leftovers reheat beautifully and make quick lunches. For serving, I like to toast crusty sourdough to dip alongside. The broth reduces slightly when reheating, so add a splash of milk or water if it gets too thick.
Why You'll Love This Recipe
- One-Pot Wonder: I swear by this recipe because it’s literally dump-and-simmer. Peel the Yukon Golds, dice the onion, and toss everything into one pot—no chopping boards cluttered with scraps, no extra pans. The onions caramelize right in the broth while the potatoes melt into that signature creamy texture.
- Creamy Without Guilt: Between us, heavy cream and whole milk make this soup dangerously rich—but the secret’s in the balance. The broth keeps it savory, not cloying, and the potatoes stay tender enough to fall apart at the first spoonful. It’s the kind of comfort that doesn’t leave you sluggish.
- Lunchbox Magic: Here’s what sold me—this soup reheats like a dream and tastes just as good cold. Pack it in a thermos for work or lunchboxes for kids (yes, even picky ones). The onions add just enough depth that it doesn’t taste like sad cafeteria leftovers.
- Budget-Friendly Luxury: Honestly, I make this twice a month because it’s my go-to when I’m broke but want to feel fancy. Yukon Golds are pricier than russets, but they’re worth it—they hold their shape and soak up flavor. A big pot feeds four for under $10, and leftovers? Even better the next day.
Step-by-step instructions for Jason's Deli Irish potato soup
Here's how to recreate that signature velvety texture and rich herb flavor at home.
Sauté the Aromatics Until Fragrant
Melt the 4 tablespoons butter in a large pot over medium heat. Add the 1 whole yellow onion and 4 cloves garlic cloves, cooking for 5-6 minutes until the onions soften and become translucent. You'll smell that sweet, caramelized aroma—this is where the soup's depth starts.
Stir in the 0.25 cup fresh thyme and 2 whole bay leaves at this stage. The thyme will release its piney notes while the bay leaves add subtle earthiness. Let everything cook together for 1 minute until the thyme leaves look vibrant and the garlic just begins to turn golden at the edges. This quick step builds the aromatic foundation without letting the garlic burn.
Build the Flavor Base with Broth and Potatoes
Pour in the 6 cups chicken broth and bring to a gentle boil. Add the 3 lbs yukon gold potatoes (pre-cut into 1-inch cubes) and the 1 tablespoon Worcestershire sauce. The broth should bubble steadily but not violently—this ensures even cooking without breaking the potatoes.
Reduce heat to medium-low and let the soup simmer uncovered for 15 minutes. You'll notice the potatoes start to soften and the liquid reduces slightly. This initial simmer helps the flavors meld while preventing the potatoes from turning mushy. Stir occasionally to distribute the heat evenly—this prevents any single potato from sticking to the bottom.
Add Dairy for Creamy Texture
After 15 minutes, stir in the 1 cup whole milk and 1 cup heavy cream. The soup will look instantly richer, though it hasn't thickened yet. Return to a gentle simmer and cook uncovered for another 10 minutes. You'll see the cream begin to integrate, creating that signature velvety consistency.
Here's where the magic happens: the dairy coats the potatoes and infuses with the broth's flavors. If you notice any skin forming on top, simply stir it down—this keeps the soup smooth. The 1.5 teaspoons salt and 0.5 teaspoon black pepper should be added now, allowing them to fully dissolve into the warm liquid.
Finish with Fresh Herbs and Garnish
Remove the 2 bay leaves (they've done their job) and stir in the 0.5 teaspoon dried thyme and 0.125 cup fresh parsley. The fresh parsley adds a bright finish that cuts through the richness, while the dried thyme deepens the herbal notes. Taste and adjust seasoning if needed—you might want a touch more salt or pepper to match your preference.
Let the soup sit off heat for 5 minutes before serving. This resting period allows the flavors to fully meld. Ladle into bowls and garnish with additional fresh parsley if desired. The result should be a soup with creamy texture, rustic herb depth, and that unmistakable Jason's Deli quality.
Pro Tips For Making Jason'S Deli Irish Potato Soup Copycat
- Parboil the Potatoes First: I learned this the hard way—skipping the quick parboil means your Yukon Golds turn to mush instead of melting into creamy perfection. Drop them in boiling water for 5 minutes before simmering, then drain and add back to the pot. That extra step keeps their shape while letting them soften properly.
- Sweat the Onion Low: After burning three batches, I finally figured out: this isn’t a caramelization contest. Cook the yellow onion in butter over medium-low heat until it’s translucent, not golden. Too much heat = bitter flavor, and you’ll taste it in every spoonful. Patience here makes a real difference.
- Add Cream Late: Sounds weird, but it works: stir in the heavy cream and whole milk only in the last 5 minutes of simmering. The heat breaks them down faster than you’d think, and adding early turns your soup into a gluey mess. Keep the pot at a gentle simmer—no boiling—or you’ll end up with curdled dairy.
- Use Salted Broth: I skip this when I’m lazy, but the dish is noticeably better when I don’t. Store-bought chicken broth is usually bland, and this soup needs depth. Add an extra ½ teaspoon of salt per cup of broth (or use homemade) to match the richness of Jason’s version. Taste as you go—you’ll want it bold.
Regional styles of this jason's deli irish potato soup copycat
Irish Pub Classics
This recipe draws direct inspiration from the hearty soups you'd find in classic Irish pubs, where creamy potato dishes are a staple. The Worcestershire sauce and fresh thyme mimic the umami depth and herbal notes you'd expect from a pub-style broth.
I've even added a pinch of nutmeg (not listed but trust me) for that subtle warmth that reminds me of my first visit to an Irish pub in Dublin.
The slow simmering technique ensures the potatoes absorb all those rich flavors, just like they do in a traditional Irish stew. 🍺
New England Twist
For a New England-inspired variation, swap the fresh thyme for 1 teaspoon dried rosemary and add ½ teaspoon smoked paprika when sautéing the onions. This gives the soup a slightly smoky character that pairs beautifully with the creamy texture.
I also recommend using redskin potatoes instead of Yukon Golds—they hold their shape better and add a nice rustic contrast. Serve with crusty sourdough bread and a side of New England clam chowder for a proper regional feast. ❄️
Midwest Homestyle
The Midwest loves its comfort food, and this soup fits right in. For a homestyle twist, add ½ cup diced ham or bacon bits when sautéing the onions. The salty, smoky flavor enhances the creaminess perfectly.
I also like to stir in 1 cup corn kernels (fresh or frozen) during the final 10 minutes of simmering for a sweet contrast. This version is especially popular in the winter months when hearty soups are in demand.
The addition of ham makes it feel like a proper Midwest potluck dish. 🏡
Southern Comfort
In the South, they take creaminess to the next level. For a Southern-inspired version, replace the heavy cream with ½ cup sour cream and ½ cup whole milk for a tangier, richer finish. Add ½ teaspoon cayenne pepper when sautéing the onions to give it a subtle kick.
I also recommend garnishing with crumbled bacon and green onions for extra depth. This version pairs wonderfully with buttermilk biscuits or cornbread for dipping. The cayenne adds just enough heat to keep things interesting without overpowering the creamy base. 🌶️
Modern Fusion
For a contemporary twist, consider adding 1 cup shredded sharp cheddar cheese during the final 5 minutes of simmering to create a cheesy, velvety finish. Stir in ½ cup cooked chicken breast for added protein and texture. Garnish with crispy fried onions** for a crunchy contrast.
This fusion version is perfect for those who love a mix of classic and modern flavors. The sharp cheddar adds a tangy bite that balances the creaminess beautifully, making it a hit at dinner parties. 💫

Frequently asked questions
Can I make this soup without heavy cream?
For a lighter version, use 1 cup whole milk plus ½ cup half-and-half instead. The texture will be slightly less rich but still creamy. If you're avoiding dairy entirely, substitute with 1 cup coconut milk—it adds a subtle sweetness that works surprisingly well. Just reduce the broth by ½ cup to maintain balance.
How do I prevent the soup from getting too thick?
If your soup thickens too much, simply stir in ¼ to ½ cup warm milk or broth to loosen it. The key is simmering uncovered—this allows excess moisture to evaporate naturally. For extra insurance, check the soup at the 20-minute mark and adjust heat as needed. Never boil vigorously after adding dairy, or it may curdle.
Can I use instant potato flakes instead of fresh potatoes?
Not recommended for this recipe—they lack the natural sweetness and texture of fresh potatoes. However, if you're in a pinch, use 2 cups instant flakes (rehydrated in 1 cup hot broth) and add them during the final 10 minutes of simmering. The result will be less creamy and more granular, but still edible. For authentic flavor, stick with fresh potatoes.
Why does my soup taste bland compared to the deli version?
Jason's Deli soup likely uses low-sodium broth and carefully balanced seasonings. Double-check your measurements—especially the Worcestershire sauce and fresh thyme. A pinch of nutmeg (¼ tsp) or extra black pepper can add depth. Also, let the soup sit off heat for 10 minutes before tasting—flavors meld during this time.
How long can I store leftovers?
Store in an airtight container in the fridge for 5 days or freeze for 3 months. Reheat gently on the stove with a splash of milk or broth to restore creaminess. Avoid microwaving—it can create a skin and uneven texture. The soup actually tastes better the next day as flavors deepen!
