This matzo ball soup first won me over at a Passover seder years ago, when one spoonful took me straight back to the kind of comfort only a nurturing kitchen can provide. I started experimenting with my own version after a dear friend shared her family’s trick of using seltzer for lift, and I never looked back. Over time I learned how to balance the delicate, savory broth with matzo balls that can be either airy floaters or satisfyingly dense sinkers, depending on what the table is craving. There is so much to love about this pot. The broth is clean yet deeply savory, the vegetables stay tender without turning mushy, and the matzo balls soak up just enough flavor while keeping their personality. On busy weeks, I will simmer the soup base while the matzo mixture chills in the fridge, then roll and cook the balls right before serving. The aroma filling the house always draws everyone into the kitchen, and there is never a single bowl left.

Ingredients

• Matzo meal: Choose a fresh, finely ground matzo meal. Use 1 cup for fluffy floaters or 2 cups for denser sinkers. Brands like Manischewitz are reliable and consistent.
• Eggs: Four large eggs bind the mixture and create lift. Fresher eggs whip better and help produce a lighter, more cohesive matzo ball structure.
• Seltzer: Three-quarter cup unflavored seltzer adds gentle lift and tenderness. Look for strong carbonation and keep it cold until mixing for best results.
• Schmaltz or avocado oil: A teaspoon adds richness. Schmaltz offers traditional chicken flavor; avocado oil keeps it neutral and dairy-free.
• Chicken thighs: Two boneless, skinless thighs brown beautifully, enriching the broth. Use up to four for a heartier soup with extra shredded chicken.
• Chicken bouillon: Better Than Bouillon (chicken) is an easy, dairy-free way to deepen flavor. Start small and adjust to taste for a clean, savory broth.
• Carrots, celery, onion: Classic aromatics that sweeten and round out the broth. Slice evenly so they cook uniformly and stay tender, not mushy.
• Parsley: A full bunch brightens the soup with fresh, herbal notes. Chop just before adding to preserve color and fragrance.

Instructions

Mix the matzo base: Whisk eggs, oil or schmaltz, salt, pepper, parsley, granulated onion, bouillon, and cold seltzer until frothy. Fold in matzo meal (1 cup for floaters or 2 cups for sinkers) just until combined; do not overmix, which toughens the texture. Chill for structure: Refrigerate the mixture for about 60 minutes. This rest allows the matzo meal to hydrate fully, helping the balls hold shape and cook evenly without cracking. Start the soup base: Heat a Dutch oven over medium heat. Add oil and brown chicken thighs 2 to 3 minutes per side for fond development. Add onion, carrots, and celery; cook 2 to 3 minutes until lightly aromatic. Simmer the broth: Add 6 to 8 cups water and 1 to 2 tablespoons chicken bouillon. Bring to a gentle boil, then reduce to a steady simmer. Cook until chicken is fully done and vegetables are tender, about 20 to 30 minutes. Cook the matzo balls: With damp hands, roll chilled mixture into walnut-size balls. Lower gently into the simmering soup or a separate pot of broth. Cover and cook about 30 minutes per batch. Do not overcrowd; they will swell. Finish and serve: Turn matzo balls mid-cooking to ensure even doneness. Stir in chopped parsley. Remove chicken, shred, and return to the pot. Taste and adjust seasoning. Ladle hot soup and matzo balls into bowls.

Storage Tips

Cool the soup to room temperature within 1 hour, then refrigerate in airtight containers. Store broth with vegetables and shredded chicken together and keep matzo balls in a separate container to maintain their texture. The soup will keep for up to 3 days in the refrigerator. For freezing, portion broth and chicken in freezer-safe containers, leaving headspace. Freeze matzo balls separately on a parchment-lined tray, then transfer to bags for up to 3 months. Reheat broth gently on the stovetop until simmering, add matzo balls, and warm through 5 to 8 minutes. Avoid boiling vigorously, which can break apart the matzo balls and soften the vegetables too much.

Ingredient Substitutions

No schmaltz on hand? Use avocado oil or neutral oil in equal measure. For a stronger chicken flavor without fat, add an extra 1 teaspoon bouillon. If you need more lift in floaters, whisk in 1/2 teaspoon baking powder to the matzo mixture. For the broth, you can substitute 4 to 6 cups low-sodium chicken stock plus 2 cups water for faster flavor. Prefer white meat? Use 1 large chicken breast, browned and simmered the same way, but expect a leaner, lighter broth. If parsley is unavailable, swap in fresh dill or a mix of dill and chives for a classic herbal note.

Serving Suggestions

Serve in warm bowls so the matzo balls hold heat longer. Garnish with extra chopped parsley or a sprinkle of fresh dill for brightness. A crisp green salad or simple cucumber salad balances the warmth of the soup. During Passover, pair with roasted asparagus or a platter of charoset and bitter greens for tradition and contrast. For a cozy weeknight, add buttered matzo or warm challah on the side for those who are not keeping kosher for Passover, and a squeeze of lemon at the table if you like a citrusy lift.

Cultural Background

Matzo ball soup is woven into Jewish culinary tradition, especially at Passover when matzo represents the bread of affliction. The matzo balls themselves—kneidlach—vary widely by family, with debates about floaters versus sinkers being a hallmark of the holiday table. Some communities scent the broth with dill, while others maintain a clearer, parsley-forward profile. Schmaltz historically added richness, particularly before modern oils were common, and it still brings a nostalgic depth. This version honors that heritage while keeping the method streamlined and accessible for everyday cooking.

Seasonal Adaptations

In spring, use fresh dill and tender young carrots for a delicate flavor. In winter, add a bay leaf and a small parsnip to deepen sweetness. For holidays, make a double batch of matzo balls and keep them warm in lightly seasoned broth so refills are seamless. During busy school weeks, swap chicken thighs for a rotisserie chicken; simmer the broth with vegetables, then add shredded rotisserie meat at the end for a quick shortcut.

Meal Prep Tips

Make the matzo mixture up to 24 hours in advance and keep it chilled, tightly covered. Cook the soup base ahead and store it separately from the matzo balls. For weekday lunches, portion individual servings of broth with vegetables and chicken in microwave-safe containers and keep matzo balls in a separate bag. Reheat soup until steaming, then add matzo balls and warm 2 to 3 minutes. Always label containers with the date and use within 3 days for best quality.

From the first simmer to the last spoonful, this bowl has a way of bringing everyone closer. I hope it becomes your family’s comfort food too, whether for a meaningful holiday or a simple, nourishing night at home.
