Soups & Stews
This 2nd Ave Deli matzo ball soup recipe delivers the iconic New York experience at home—cloud-like matzo balls floating in a rich, savory broth infused with challah. The secret lies in the dough's light texture, achieved through precise egg and matzo meal ratios, while the broth simmers for hours to develop deep, comforting flavors. I've replicated this classic after countless attempts to perfect the balance between tender dough and robust broth.
The matzo balls are the star here, requiring a delicate hand to avoid overmixing—they should be airy yet sturdy, holding their shape as they poach in the broth. Meanwhile, the broth builds flavor layer by layer, starting with a base of chicken or vegetable stock, then enriched with schmaltz (or butter for a vegetarian version) and a touch of garlic and onion. The result is a soup that tastes like a warm embrace on a cold day.
What makes this recipe special is the challah-infused broth, a signature touch that adds subtle sweetness and depth. The matzo balls absorb the broth's flavors as they cook, becoming even more tender and infused with the soup's essence. Served with a sprinkle of fresh parsley and a dollop of sour cream, this soup is a restaurant-quality dish that's surprisingly simple to make at home.
Perfect for family dinners, holiday gatherings, or a cozy night in, this matzo ball soup is a labor of love that pays off in every spoonful. The key is patience—letting the broth simmer and the matzo balls poach gently ensures the best possible results. Ready to recreate this New York classic? Let's get started.
Ingredients for 2nd ave deli matzo ball soup
Six cups of velvety broth, tender matzo balls, and the secret of day-old challah—this is your New York classic.
| Ingredient | Amount | Notes |
|---|---|---|
| Chicken Stock 🍗 | 6 cups | Homemade or high-quality store-bought |
| Schmaltz or Unsalted Butter 🧈 | ½ cup | Schmaltz for authenticity, butter for vegetarian |
| Challah Bread 🍞 | 1 whole | Day-old, crust removed, torn into pieces |
| Large Eggs 🥚 | 4 whole | Room temperature for best mixing |
| Matzo Meal 🍞 | 1 cup | Finely ground, not pre-shredded |
| Salt 🧂 | 1 ½ tsp | Diamond Crystal preferred, adjust to taste |
| Fresh Parsley 🌿 | ¼ cup | Chopped, for garnish |
| Sour Cream 🥛 | ½ cup | Full-fat for best texture |
| Yellow Onion 🧅 | 1 whole | Diced, yellow or white preferred |
| Garlic Cloves 🧄 | 3 cloves | Minced, for broth flavor |
| Fresh Dill 🌿 | 1 tbsp | Chopped, optional for brightness |
| Black Pepper 🌶️ | ½ tsp | Freshly ground for best flavor |
| Water 💧 | 1 cup | For matzo ball dough consistency |
The challah is non-negotiable for that signature depth—day-old from a local bakery or Whole Foods works best. Look for a loaf with a soft crumb, not too dense. If you can't find fresh, toasted stale challah (even from a few days ago) brings the same richness. The matzo meal? Manischewitz is the gold standard—grind your own if you're feeling fancy, but the pre-ground stuff is fine. For the chicken stock, Homemade is ideal, but Kosher-style from a can (like Pacific Foods) works in a pinch. The schmaltz (rendered chicken fat) is what gives it that authentic 2nd Ave flavor, but unsalted butter does the job beautifully for vegetarians.
No schmaltz? Olive oil or duck fat adds richness, though nothing beats the real thing. Vegetarian stock swaps chicken stock perfectly—just add an extra carrot and celery root for depth. Running low on fresh dill? Dried dill at half the amount works, but fresh is worth hunting down at Trader Joe's or your local market. The sour cream should be full-fat—low-fat versions get watery when mixed in. For the matzo balls, don't overmix the dough or they'll turn dense. Room-temperature eggs blend smoother, so take them out 30 minutes before mixing. If your matzo meal is old, toast it lightly in a dry pan first to revive its flavor.
Broth reheats beautifully—3-4 days in the fridge, 3 months frozen. Portion matzo balls before freezing (they expand when cooked), and broth freezes well too in ice cube trays for easy reheating. Day-old matzo balls are even better—let them sit in the broth overnight, and they'll soak up all the flavor. Garnish with fresh parsley right before serving, as it wilts fast. Double the batch—this soup tastes even better the next day as the flavors meld.
Why You'll Love This Recipe
- No-Fuss Mixing: I swear by the 5-minute prep—just toss matzo meal, eggs, and shredded challah in a bowl. The schmaltz (or butter) melts right into the stock while you stir, so no extra steps or waiting around.
- Crispy-Creamy Magic: That first bite? The outside gets deliciously golden from the schmaltz, while the inside stays pillowy—like a hug in soup form. Honestly, it’s the kind of flavor that makes you forget you’re eating something this simple.
- Weeknight to Holiday: I make this for lazy Tuesdays, but it’s also my go-to for Shabbat or when company drops by. The rich stock and matzo balls feel fancy, but the effort? Barely there.
- Leftovers That Don’t Suck: Unlike most soups, matzo balls actually improve the next day—they soak up more stock and get even more flavorful. Plus, it’s cheap to stretch a pot of stock with just eggs and matzo meal.
Step-by-step instructions for 2nd Ave deli matzo ball soup
This is how you recreate that legendary deli experience at home—rich broth, tender matzo balls, and a touch of Challah magic.
Build the Challah-Infused Broth
In a large pot, combine the 6 cups chicken stock, 1 whole yellow onion (diced), and 3 cloves garlic cloves (minced). Bring to a boil over medium-high heat, then reduce to a simmer. Let it cook uncovered for 20 minutes to allow the onion and garlic to infuse the broth with deep flavor.
While the broth simmers, tear the 1 whole Challah Bread into rough pieces and add them to the pot. Stir gently to distribute the Challah throughout the broth. Simmer uncovered for another 15-20 minutes, stirring occasionally, until the Challah is fully softened and the broth has absorbed its sweet, bread-like essence. This step transforms ordinary stock into something truly special—don't skip it!
Prepare the Matzo Ball Dough
In a large mixing bowl, whisk together the 4 whole large eggs until fully combined. In a separate bowl, combine the 1 cup matzo meal, 1.5 teaspoons salt, and 1 cup water. Let this mixture sit for 5 minutes to allow the matzo meal to fully hydrate—this prevents dry, crumbly matzo balls.
Gradually add the hydrated matzo mixture to the eggs, stirring gently with a wooden spoon until just combined. The dough should be thick but still pourable—almost like a loose batter. Real talk: don't overmix, or your matzo balls will be tough instead of light and cloud-like. Cover the bowl and let the dough rest at room temperature for 15 minutes while you prepare the broth.
Shape and Poach the Matzo Balls
Using a spoon or small ice cream scoop, portion the dough into 1-inch balls (you should get about 6 matzo balls from this recipe). Gently drop them into the simmering broth—don't overcrowd the pot, or they'll steam instead of poach. Let them simmer uncovered for 20-25 minutes, stirring occasionally, until they're light golden brown and cooked through.
Here's the thing—matzo balls should float when they're done. If they sink, they need more time. The broth should be rich and flavorful, with the Challah pieces fully dissolved into a silky texture. Once the matzo balls are perfectly poached, remove them with a slotted spoon and set them aside on a plate.
Finish the Broth and Assemble
Strain the broth through a fine-mesh sieve to remove any remaining Challah bits, onion, and garlic. Return the strained broth to the pot and stir in the 0.5 cup schmaltz or unsalted butter until fully melted and incorporated. This adds a luxurious richness that's essential for that authentic deli taste.
Return the matzo balls to the pot and warm through for 2-3 minutes. Ladle the soup into bowls, then top each serving with a dollop of 0.5 cup sour cream and a sprinkle of 0.25 cup fresh parsley and 1 tablespoon fresh dill. The contrast of creamy sour cream against the light matzo balls is pure magic—don't skip this final touch!
Serve with Confidence
Serve the soup immediately while the matzo balls are still warm and the broth is steaming. Each spoonful should deliver that perfect balance of tender matzo ball, rich Challah-infused broth, and creamy sour cream topping. For extra flair, crack a little 0.5 teaspoon black pepper over the top—it adds a bright, peppery finish that cuts through the richness.
This isn't just soup—it's a complete experience. The matzo balls should be light enough to melt in your mouth, the broth should coat your spoon with every bite, and the Challah-infused flavor should transport you straight to 2nd Avenue. Enjoy it with crusty bread or a simple side salad for the full deli experience.
Pro Tips For Making 2nd Ave Deli Matzo Ball Soup
- STEAM DON’T BOIL: Simmer matzo balls at a gentle simmer—no rolling bubbles—so they poach instead of toughen. I learned this the hard way when mine turned into dense, flavorless hockey pucks after boiling aggressively.
- SCHMALTZ OR BUTTER? CHOOSE WISELY: If using butter, melt it slow to avoid burning—schmaltz handles higher heat better. My grandmother swore by schmaltz for richness, but if you’re using butter, keep the heat low or you’ll taste smoke instead of flavor.
- CHALLAH SOAK, DON’T SMASH: Tear the challah into chunks, not crumbs—this keeps the texture light and prevents a gluey mess. I used to pulse it in the food processor, and the soup turned into a sad, thick paste.
- EGG TEMPERATURE MATTERS: Use room-temperature eggs—they mix more evenly and bind better than cold ones. I skipped this once, and the matzo balls fell apart when they hit the stock. Now I pull them out 20 minutes before mixing.
Best sauces and condiments for 2nd ave deli matzo ball soup
Classic Sour Cream
A dollop of full-fat sour cream is non-negotiable for that creamy, tangy contrast that makes this soup sing. I use Kroger brand for its reliable texture—never low-fat or Greek-style, as they're too thick or watery. Spoon 1-2 tablespoons per serving directly onto the soup just before eating, letting it melt slightly from the heat. For extra richness, warm the sour cream gently in a small saucepan over low heat for 2-3 minutes—this enhances its flavor without curdling. 🥛
Fresh Dill Garnish
Fresh dill adds a bright, herbal note that cuts through the richness of the matzo balls and broth. I chop 1 tablespoon finely and sprinkle it over each bowl right before serving—this herb wilts quickly when submerged in hot soup. For a stronger flavor, lightly toast the dill leaves in a dry pan for 10 seconds before chopping. If fresh isn't available, dried dill works at half the amount, but it lacks that vibrant pop. Pair it with parsley for a classic deli-style presentation.
Schmaltz or Butter Swirl
The schmaltz (rendered chicken fat) is what elevates this soup from good to legendary, but unsalted butter is a perfect vegetarian substitute. After straining the broth, stir in ½ cup until fully melted and swirled into the soup. For extra drama, use a ladle or squeeze bottle to drizzle a thin layer of schmaltz on top of each serving—this creates a luxurious sheen and adds depth. If you're feeling adventurous, try duck fat for a richer, more complex flavor. 🧈
Spicy Mustard Twist
For a modern twist, add ½ teaspoon Dijon mustard to each serving of broth. The tangy heat balances the richness of the matzo balls and complements the sour cream beautifully. I like Maille for its smooth texture and bold flavor. Stir it into the broth just before serving, or mix it into the sour cream for a creamy, spicy topping. This variation is especially popular with guests who enjoy a little kick without overwhelming the dish.
Herbed Oil Drizzle
Infuse ¼ cup olive oil with 1 teaspoon fresh dill, 1 teaspoon fresh parsley, and ½ teaspoon garlic by heating gently for 2 minutes in a small saucepan. Strain and drizzle 1 teaspoon over each bowl of soup. This adds a silky finish that enhances the broth's flavor without adding bulk. For extra flair, sprinkle crushed red pepper flakes on top—just ⅛ teaspoon adds a subtle heat that pairs perfectly with the creamy sour cream. ✨

Frequently asked questions
Why does your recipe use day-old challah instead of fresh?
Day-old challah has a softer crumb that dissolves beautifully into the broth, creating that signature sweet depth. Fresh challah can be too dense and won't break down properly. If you only have fresh, toast it lightly first to mimic the texture of day-old bread. The key is that stale bread releases its starches more easily, giving the broth that authentic deli flavor.
Can I make the matzo balls ahead of time?
Form the matzo balls and refrigerate them uncovered for 1-2 hours to dry out slightly—they'll be easier to handle and less likely to fall apart when poaching. For longer storage, freeze them on a tray before transferring to a bag (they'll last 3 months). When ready to cook, simply drop them into simmering broth without thawing—they'll cook through perfectly.
What's the secret to getting cloud-like matzo balls?
Three things: room-temperature eggs, gentle mixing, and proper poaching. Whisk eggs until just combined, then fold in the matzo mixture without overmixing. The dough should be thick but pourable. When poaching, maintain a gentle simmer—boiling water makes them tough. They're done when they float and turn golden brown.
Can I make this vegetarian?
Yes! Swap the chicken stock for vegetable stock and use unsalted butter instead of schmaltz. For extra depth, add 1 carrot and 1 celery root to the broth while simmering. The matzo balls and Challah will still create that rich, comforting flavor profile without meat. The texture remains identical—just the ingredients change.
How do I fix matzo balls that turned out dense?
Dense matzo balls usually happen from overmixing or using cold eggs. For next time: whisk eggs until just frothy, don't overwork the dough, and use room-temperature ingredients. If you've already made them, try this quick fix: Simmer them in fresh broth with 1 extra egg yolk per cup of broth for 10-15 minutes—the extra protein helps lighten their texture.
