Breakfast & Brunch
This egg and onion matzo recipe transforms humble matzo into crispy, shatter bites topped with perfectly poached eggs—a dish that bridges tradition and modern comfort food. The secret lies in soaking the matzo just enough to soften it without turning it soggy, then baking until golden and crisp. I first discovered this recipe during a Passover brunch when I wanted something hearty yet light, and it became an instant favorite.
The foundation of this dish is the onions, caramelized until sweet and tender, creating a rich base that pairs beautifully with the crispy matzo. When you top it with poached eggs, the runny yolks melt into the warm matzo, creating a luxurious texture that feels indulgent yet balanced. The dish is simple enough for a weeknight breakfast but impressive enough for guests, making it a versatile addition to any brunch spread.
What makes this recipe stand out is its ability to deliver crispy edges and a tender center, all while keeping the dish light and satisfying. The matzo absorbs the flavors of the onions and eggs, creating a harmonious blend of textures and tastes. Serve it with a sprinkle of fresh herbs or a dollop of sour cream for added freshness, and you’ll have a dish that’s both nostalgic and elevated.
Whether you're looking for a Passover-inspired meal or a creative way to use matzo, this recipe delivers. The process is straightforward, and the results are consistently delicious—proof that sometimes, the simplest ingredients can create the most memorable dishes. Let’s get cooking!
Ingredients for egg and onion matzo
Crispy matzo bites, sweet onions, and runny yolks—this brunch game-changer needs just 10 ingredients.
| Ingredient | Amount | Notes |
|---|---|---|
| Matzo Crackers 🍞 | 12 whole | Plain, square matzo preferred |
| Yellow Onions 🧅 | 1 whole | Thinly sliced, about 2 cups |
| Large Eggs 🥚 | 4 whole | Fresh, room temperature |
| Unsalted Butter 🧈 | 2 tbsp | For caramelizing onions |
| Salt 🧂 | ½ tsp | Kosher or sea salt |
| Black Pepper 🌶️ | ¼ tsp | Freshly ground |
| White Vinegar 🍶 | 1 tbsp | For poaching eggs |

The matzo is the star here, so pick the sturdiest brand you can find—those flimsy, crumbly ones won't hold up. Manischewitz is my go-to, but any plain matzo works. For the onions, yellow onions are ideal—they caramelize faster than sweet onions. If you're short on time, pre-sliced onions from the salad bar section at Trader Joe's save chopping work. The key is slicing them thin enough to soften quickly but not so thin they burn. I usually eyeball it—about the thickness of a dime.
No fresh chives? Dried chives or green onion tops work in a pinch, but fresh is best. For the eggs, room temperature eggs poach better—just take them out of the fridge 30 minutes before cooking. The butter matters here—unsalted gives you control over seasoning. If you're avoiding dairy, olive oil works just as well for caramelizing. The matzo soaks up flavors fast, so don't skip the salt—it balances the richness of the eggs. For extra crunch, bake the matzo at 375°F instead of 350°F—it crisps up faster.
Matzo stays crispy for about 15 minutes after baking, so make it fresh if you can. Store leftover baked matzo in an airtight container for 2 days—it gets soft but still works for dipping. The caramelized onions keep for 5 days in the fridge, but I always make extra because they're great on toast. Poached eggs? Make them ahead and store in cold water—they reheat perfectly when you're ready to serve. This dish reheats beautifully—just pop it in a 350°F oven for 5 minutes to crisp up the matzo again.

Step-by-step instructions for crispy egg and onion matzo bites
Here's how to create shatteringly crisp matzo topped with silky poached eggs and caramelized onions.
Caramelize the Onions Until Sweet and Golden
Melt the 2 tablespoons unsalted butter in a medium skillet over medium heat. Add the thinly sliced yellow onions and cook for 15-20 minutes, stirring occasionally. You're looking for onions that turn deep golden brown and develop a sweet, jammy texture.
Here's the thing - don't rush this step. The onions should release their moisture and reduce down significantly. When they're ready, they'll smell incredible and look almost glossy. Season with the 0.5 teaspoon salt and 0.25 teaspoon black pepper, then remove from heat and set aside. These caramelized onions will be the flavor base for your bites.
Prepare the Matzo for Baking
Preheat your oven to 375°F. Line a baking sheet with parchment paper and lightly brush it with the 0.5 cup vegetable oil. Arrange the 12 whole matzo crackers on the prepared sheet, leaving about 1 inch between each piece. The oil will help create that signature crispy texture we're after.
Bake the matzo for 5-7 minutes until they're golden brown at the edges but still slightly crisp. Watch them closely - matzo burns easily once it reaches that perfect golden stage. Remove from oven and immediately top each cracker with about 1 tablespoon of the caramelized onions. Return to the oven for just 1-2 minutes to warm through.
Poach the Eggs to Silky Perfection
Fill a small saucepan with about 4 inches of water and bring to a gentle simmer. Add the 1 tablespoon white vinegar - this helps the eggs coagulate more evenly. Crack each of the 4 large eggs into a small bowl first, then carefully slide them into the simmering water using a spoon.
Poach for exactly 3 minutes for runny yolks or 4 minutes for firmer yolks. You'll know they're ready when the whites are set but the yolks are still vibrant. Using a slotted spoon, gently transfer the poached eggs to paper towels to drain briefly. Keep them warm while you finish assembling the bites.
Assemble and Garnish the Matzo Bites
Place one warm matzo cracker on each serving plate. Top each with one poached egg and a generous spoonful of the caramelized onions. Drizzle with a small amount of the 0.25 cup sour cream if using, and finish with the chopped fresh chives. The contrast of crispy matzo, silky egg, and sweet onions is what makes this dish special.
Serve immediately while everything is at its peak - the matzo should shatter with each bite, the eggs should be perfectly poached, and the onions should be sweet and caramelized. This dish comes together quickly but the flavors develop beautifully when served fresh from the oven.
Pro Tips For Making Egg And Onion Matzo
- Crush the Onions First: I learned this the hard way—slicing onions into thin rings and frying them whole leads to uneven cooking. Instead, pulse them in a food processor until they’re fine but not paste-like (think coarse sand). This ensures they soften fast and caramelize properly without turning to mush.
- Use Cold Butter, Not Melted: Dumping melted butter into the pan first makes the matzo soggy. Cut the cold butter into small cubes and let it sizzle in the pan for 30 seconds before adding onions. This builds flavor and prevents the matzo from absorbing moisture too soon.
- Salt the Eggs Before Mixing: If you wait until the end, your dish will taste flat. Crack the eggs into a bowl, add a pinch of salt, and whisk them vigorously. The salt dissolves better in the raw egg, and the flavor distributes evenly instead of clumping.
- Break the Matzo, Don’t Layer It: Stacking whole matzo crackers creates uneven crispness. Instead, break them into 1-inch pieces and scatter them in a single layer. This guarantees every bite gets that perfect crunch, not just the top layer. (Yes, even if it looks messy.)
Common mistakes when making this dish
Over-Soaking Matzo
Matzo absorbs moisture like a sponge, and over-soaking it before baking is a common mistake that leads to soggy, unappetizing bites. The recipe calls for baking the matzo dry first to create that perfect crispy texture. If you're tempted to soak the matzo in advance to save time, resist! Even a quick dip in water or egg wash before baking will make it too soft. Instead, bake the matzo dry for 5-7 minutes at 375°F, then add your toppings for just 1-2 minutes to warm through. 💡
Skipping the Oil Brush
Many home cooks forget to brush the baking sheet with vegetable oil before arranging the matzo crackers. This step is crucial for achieving that signature crispy texture. Without the oil, the matzo will bake unevenly and may stick to the sheet. I always use a light coat of oil—about 0.5 cup spread thinly over the entire sheet. This ensures the matzo gets crispy edges while staying tender in the center.
Rushing the Onion Caramelization
One of the biggest mistakes is not caramelizing the onions long enough. The onions should cook until they're deep golden brown and sweet, which takes about 15-20 minutes over medium heat. If you rush this step, the onions will taste raw and bitter, rather than sweet and jammy. I like to stir them occasionally and let them reduce down significantly. Patience here makes all the difference in flavor. ⏳
Poaching Eggs Too Long
Over-poaching eggs turns them from silky perfection to rubbery disappointment. The recipe calls for 3 minutes for runny yolks or 4 minutes for firmer yolks. Any longer, and the whites will become tough and the yolks will firm up completely. I always use a gentle simmer and a small saucepan to maintain even heat. A slotted spoon makes transferring the eggs to paper towels easy, keeping them warm and ready to serve.
Assembling Too Early
Another common mistake is assembling the matzo bites too soon after baking. The matzo stays crispy for only about 15 minutes after coming out of the oven. If you assemble it too early, the matzo will soften and lose its texture. Instead, bake the matzo, top with onions, and return to the oven for just 1-2 minutes to warm through. Then, add the poached eggs right before serving to keep everything at its best.
Ignoring Fresh Herbs
While not mandatory, fresh chives add a bright, herbaceous note that balances the richness of the eggs and onions. Many cooks skip this step, thinking it’s optional, but those fresh chives elevate the dish. If you don’t have fresh chives, dried chives or green onion tops work in a pinch, but fresh is always best. A sprinkle of 2 tbsp chopped chives adds that final touch of freshness that makes the dish feel complete. 🌿

Frequently asked questions
Can I use regular matzo crackers instead of whole matzo?
While the recipe calls for whole matzo crackers, you can absolutely use smaller matzo crackers or even break larger ones into bite-sized pieces. Just adjust the baking time slightly—smaller pieces may crisp up faster (3-5 minutes instead of 5-7 minutes). The key is maintaining that perfect crispy texture, so keep an eye on them in the oven.
How do I make this dish vegetarian-friendly?
This recipe is already vegetarian, but if you want to add more depth, consider sautéing mushrooms with the onions or topping with vegan sour cream. For extra protein, sprinkle with crumbled feta or goat cheese. The dish naturally pairs well with plant-based ingredients while keeping the core flavors intact.
Can I prepare this ahead of time?
Yes, but with a few adjustments. Caramelize the onions and bake the matzo bites up to 1 day ahead—store them separately in airtight containers. Reheat the matzo bites at 350°F for 5 minutes to restore crispiness. Poach the eggs fresh before serving, as they don't reheat well. Assemble just before eating for the best texture.
What if I don't have fresh chives?
No problem! Use dried chives (start with 1 teaspoon and adjust to taste) or finely chopped green onions. For a different flavor profile, try parsley or basil. Even a pinch of smoked paprika adds warmth. The key is adding some freshness—just don't skip the garnish entirely!
Can I make this dish gluten-free?
Traditional matzo contains gluten, but you can substitute with gluten-free flatbread or crispy gluten-free crackers. For the egg and onion topping, use certified gluten-free ingredients. The texture will differ slightly (less crispy), but the flavors will still shine. Always check labels to avoid cross-contamination.
