Breakfast & Brunch
This boiled egg filling recipe transforms simple eggs into a versatile, restaurant-worthy component for everything from crispy wonton cups to fluffy pastries. The secret lies in achieving silky scrambled centers while maintaining a delicate, airy texture—perfect for stuffing, layering, or serving as a standalone dish. I developed this method after struggling with dry, rubbery egg fillings, and it now delivers consistent, professional results every time.
The process starts with properly boiled eggs—just enough time to create a firm but tender yolk that scrambles into a velvety consistency. What sets this apart is the technique for breaking down the eggs into fine, even pieces while keeping them moist. A touch of cream cheese or mayonnaise binds the filling together, ensuring it stays cohesive whether baked, fried, or spooned.
What you’ll end up with is a filling that’s crispy when baked (like in wonton cups) or silky when served warm, with a subtle savory flavor that pairs beautifully with herbs, cheese, or a dash of mustard. The versatility makes it ideal for breakfast wraps, savory tarts, or even a gourmet egg salad twist. Best of all, it keeps well in the fridge for up to three days, ready to elevate any dish.
Whether you’re prepping for a brunch spread or a quick weeknight meal, this filling delivers restaurant-quality texture and flavor with minimal effort. Let’s get started—your taste buds (and guests) will thank you.
Ingredients for boiled egg filling
Eight ingredients transform boiled eggs into crispy, silky filling for wonton cups and beyond.
| Ingredient | Amount | Notes |
|---|---|---|
| Large Eggs 🥚 | 8 whole | Hard-boiled, peeled, room temperature |
| Cream Cheese 🧀 | 4 oz | Full-fat, room temperature |
| Mayonnaise 🥫 | ¼ cup | High-quality, room temperature |
| Shallots 🧅 | 2 whole | Finely minced, about 2 tbsp |
| Fresh Dill 🌿 | ¼ cup | Chopped, stems removed |
| Fresh Chives 🌿 | ⅛ cup | Finely chopped, for garnish |
| Dijon Mustard 🌶️ | 1 tbsp | For subtle tang |
| Salt 🧂 | ½ tsp | Diamond Crystal kosher salt |
| Black Pepper 🌶️ | ¼ tsp | Freshly ground |
| Unsalted Butter 🧈 | 2 tbsp | Cold, cubed for binding |
| Vegetable Oil 🫒 | 1 tbsp | For scrambling eggs |
The eggs are non-negotiable—large eggs yield the best texture, and they must be boiled just right: 9-10 minutes for a firm but tender yolk. I use a slotted spoon to transfer them to an ice bath immediately, which stops the cooking and keeps them from getting rubbery. Trader Joe's sells pre-boiled eggs in the refrigerated section, which saves time if you're in a rush. The cream cheese and mayo are the secret binders—full-fat versions ensure the filling stays moist and cohesive. If you're watching calories, you can reduce the mayo by half and add a splash of milk, but trust me on the full-fat version for that restaurant-quality texture.
No fresh dill? Dried dill at one-third the amount works in a pinch, but it lacks that bright, fresh flavor. The shallots add depth—if you've got a jar of minced shallots, that's perfect, but fresh is better. Substitute green onions if needed, but they're milder. For extra richness, add a tablespoon of sour cream to the mix. The butter should be cold when you add it—this prevents the filling from getting greasy. If you're prepping ahead, make the filling up to a day in advance, but hold off on adding the herbs until right before serving so they stay vibrant. The mustard is optional but adds a nice tang that balances the richness.
This filling keeps beautifully in the fridge for up to 3 days, sealed in an airtight container. For longer storage, portion it into 1-ounce silicone molds—they freeze perfectly for up to 3 months. When reheating, a quick 30-second microwave zap keeps it silky, while baking at 375°F for 10-12 minutes gives it that crispy texture ideal for wonton cups. I always make extra—it disappears fast during brunch or as a quick snack with crackers. The key to success? Don't overmix the filling after adding the butter, or it'll get tough.
Why You'll Love This Recipe
- No Chopping Nightmare: I’ll be real—this recipe takes three ingredients that need chopping: shallots. That’s it. Even my toddler could handle it (and has, while I burnt the toast).
- Creamy With Crunch: The boiled eggs stay perfectly firm while the cream cheese and mayo blend into that velvety, tangy base—like a fancy deviled egg’s dream team, but way easier. That fresh dill? It’s the secret weapon that makes it taste like a restaurant dish.
- Party in a Jar: Between us, this filling is my go-to for last-minute appetizers. Stuff it in pita pockets, slather it on crackers, or let the kids "decorate" their own mini sandwiches. Zero fuss, all flavor.
- Pantry Goldmine: Honestly? This recipe costs me about $3 for a batch that’ll last a week. Use it for lunch, pack it in bento boxes, or toss it in salads—it’s the ultimate "I forgot to meal prep" lifesaver. (Yes, even on a Tuesday night.)
Step-by-step instructions for perfect boiled egg filling
Here's how to create that dreamy, ultra-crispy wonton cup filling with a velvety scrambled center.
Scramble the Eggs to Silky Perfection
Heat the 1 tablespoon vegetable oil in a nonstick skillet over medium-low heat until just shimmering. Crack the 8 whole Large Eggs into a bowl, add the 0.5 teaspoon salt and 0.25 teaspoon black pepper, and whisk vigorously for 30 seconds until the whites are completely frothy and yolks are broken up.
Pour the eggs into the skillet and let them sit undisturbed for 15 seconds—this creates those beautiful soft curds. Using a silicone spatula, gently push the eggs from one side of the pan to the other in small sections, folding them as you go. You're aiming for creamy, custard-like texture, not dry or rubbery. Remove from heat when still slightly underdone—they'll finish cooking from residual heat.
Mix the Cream Cheese Base
While the eggs cool slightly, transfer them to a large mixing bowl. Add the 4 oz cream cheese and 2 tablespoons unsalted butter (cold and cubed) to the warm eggs. Using a hand mixer on low speed, blend until the butter is completely incorporated and the mixture is smooth. This prevents lumps that would make your filling grainy.
Add the 0.25 cup mayonnaise, 1 tablespoon Dijon mustard, and the 2 whole Shallots (finely minced). Mix on medium speed for 1 minute until everything is fully combined. The mixture should be thick but still spreadable—if it's too stiff, add 1 teaspoon water at a time until it reaches the right consistency. Here's the thing—room temperature ingredients are crucial. Cold cream cheese or butter will create a lumpy filling.
Fold in Herbs and Season
Gently fold in the 0.25 cup chopped fresh dill and 0.125 cup finely chopped fresh chives using a rubber spatula. The herbs should be evenly distributed but still visible—this adds that fresh, vibrant flavor that makes this filling special. Taste and adjust seasoning if needed, though the eggs and cream cheese should already be perfectly balanced.
Let the filling rest at room temperature for 10 minutes before using. This allows all the flavors to meld together and the texture to stabilize. If you're making wonton cups, pipe or spoon the filling into the crispy wonton wrappers immediately after resting—this ensures they stay crispy while the filling sets.
Assemble and Bake (For Wonton Cups)
Preheat your oven to 375°F. If using wonton cups, fill each with 1 teaspoon of the egg filling, pressing gently to create a smooth surface. For extra crispiness, brush the edges with a little vegetable oil before baking. Place the filled wonton cups on a parchment-lined baking sheet.
Bake for 8-10 minutes until the edges are deep golden brown and the filling is just set—it should still have a slight wobble in the center. The filling should be creamy and smooth with no visible lumps. Serve immediately while still warm for that perfect contrast of crispy wonton cups with silky, flavorful centers.
Pro Tips For Making Boiled Egg Filling
- Boil Eggs 6 Minutes: I learned this the hard way—soft-boiled eggs (5 minutes) get mushy when chopped, and overdone ones (8+ minutes) turn chalky. Six minutes gives you a firm yolk that holds shape but still melts slightly when mixed with cream cheese, which is exactly what you want in this filling.
- Chop Shallots Small: Skip the big slices—finely minced shallots (almost like a paste) disappear into the filling without overpowering. Use the pulse function on a food processor for consistency, then wipe down the bowl immediately (trust me, that sticky shallot residue is a nightmare to clean).
- Mix Cold Ingredients: Let your boiled eggs cool completely before chopping, and keep the cream cheese and mayo refrigerated until the last step. Warm ingredients make the filling greasy and separate, and nobody wants a lumpy egg salad filling—especially when you’re rolling it into delicate pastries.
- Add Dill Last: Fresh dill loses its brightness when mixed too early. Instead, chop it just before folding everything together, and save a handful for garnish. If you’re using dried dill, halve the amount—it’s way more concentrated than you’d think, and you’ll regret it if you overdo it.
Best sauces and condiments for this recipe
Creamy Dill Sauce
This rich, herby sauce elevates your egg filling into a gourmet experience. Whisk together ½ cup sour cream, 2 tablespoons chopped fresh dill, 1 teaspoon lemon juice, ½ teaspoon Dijon mustard, and a pinch of salt. Drizzle over wonton cups or spoon alongside the filling for a cool contrast to warm eggs. I love using St. Ives brand sour cream—it's tangy enough to cut through the richness. 🌿
Spicy Sriracha Mayo
For a kick, mix 2 tablespoons mayonnaise with 1 teaspoon sriracha and a dash of hot sauce. This fiery condiment pairs perfectly with the silky egg filling, especially when served in crispy wonton cups. I recommend Huy Fong Sriracha for that signature heat. Add a pinch of smoked paprika for depth—it’s a game-changer for brunch spreads. 🌶️
Garlic Aioli
Blend ½ cup mayonnaise, 1 roasted garlic clove, 1 teaspoon lemon zest, and ½ teaspoon garlic powder until smooth. This fragrant aioli adds a luxurious touch to egg fillings, especially when used as a dip or drizzled over baked wonton cups. For extra richness, add 1 tablespoon crème fraîche. I use Hellmann’s mayonnaise for a creamy base. 🧄
Classic Hollandaise
For a luxurious twist, serve your egg filling with a silky hollandaise sauce. Whisk 3 egg yolks, 1 tablespoon lemon juice, and ½ cup melted butter over a double boiler until thickened. Season with salt and white pepper. This sauce transforms your filling into a brunch-worthy centerpiece. I use Land O’Lakes butter for its rich flavor. 🍳
Herb-Infused Oil
Infuse ½ cup olive oil with 1 tablespoon chopped fresh parsley, 1 tablespoon fresh dill, and 1 garlic clove (lightly crushed) by heating gently for 5 minutes. Strain and drizzle over baked wonton cups or spoon alongside the filling. This aromatic oil adds brightness and moisture to every bite. I use California Olive Ranch oil for its mild, fruity notes. 🫒

Frequently asked questions
Can I use this filling for sweet pastries instead of savory dishes?
For sweet variations, swap the shallots for 1 teaspoon vanilla extract and 1 tablespoon honey, and replace the dill with 1 teaspoon cinnamon. Add 2 tablespoons powdered sugar and a pinch of nutmeg for a custard-like filling perfect for cream puffs or éclairs. The cream cheese base keeps it rich and stable when baked.
Why does my egg filling turn out dry or grainy?
Dry or grainy filling usually happens from overmixing or using cold ingredients. Always ensure your eggs, cream cheese, and butter are room temperature before mixing. Also, avoid overmixing after adding the cold butter—just fold until combined. For extra moisture, add 1 teaspoon water or 1 tablespoon milk if needed.
How do I store leftover filling?
Store in an airtight container in the fridge for up to 3 days. For longer storage, portion into 1-ounce silicone molds and freeze for up to 3 months. Thaw overnight in the fridge. Reheat gently in the microwave (30 seconds) or oven (375°F for 10 minutes) to maintain texture.
What's the best way to reheat baked wonton cups?
For crispy results, reheat in a 375°F oven for 5-7 minutes on a parchment-lined tray. If using a microwave, cover with a damp paper towel and zap for 20-30 seconds—this keeps the filling warm without making the wontons soggy. Air fryers work too (350°F for 3 minutes) for extra crunch.
Can I make this filling without cream cheese?
Yes! Substitute with ½ cup sour cream or ¼ cup mayonnaise + 2 tablespoons milk for creaminess. For a lighter option, use 2 tablespoons Greek yogurt (full-fat for best texture). The key is maintaining moisture—just ensure your replacement is room temperature and mix gently to avoid lumps.
