Costco Sous Vide Egg Bites Recipe: Crispy-Wonton Cups With Silky Yolk Magic

Costco sous vide egg bites transform ordinary breakfast into a restaurant-worthy experience with their crispy-wonton cups and perfectly silky yolks. 🔥 The secret lies in precise temperature control—cooking at 140°F for 30 minutes ensures tender eggs while the won ton wrappers stay irresistibly crispy. This method eliminates guesswork, delivering consistent results every time, even for beginners.

What sets these apart is the balance of textures: the outer cups remain shatteringly crisp, while the inside stays rich and custardy. The sous vide process preserves the egg's natural richness, preventing overcooking or rubbery centers. Using Costco's bulk ingredients keeps prep simple—just mix, assemble, and cook—while still achieving gourmet quality.

Once sealed and cooked, the egg bites develop a golden crust that contrasts beautifully with the creamy egg filling. The technique works with any protein—cheese, ham, or veggies—making it endlessly adaptable. For best results, let them rest briefly before serving to ensure the wrappers stay crispy.

Perfect for meal prep or a special brunch, these egg bites reheat beautifully in the air fryer for an extra-crispy finish. The professional results make them ideal for impressing guests or treating yourself to a luxurious morning. Let's get started!

Ingredients for costco sous vide egg bites

Costco's bulk ingredients make these restaurant-quality egg bites effortless to prepare with crispy won ton cups and velvety yolks.

The won ton wrappers are the foundation—Costco's bulk package saves money and ensures consistent quality. Look for wrappers with a slight sheen; they crisp best when fresh. For the eggs, room temperature is critical—they cook more evenly and prevent cracking during sealing. The cheese selection matters too: sharp cheddar melts beautifully and adds depth, while pre-shredded varieties often contain anti-caking agents that prevent proper melting. If you're feeling adventurous, swap the cheddar for a mix of Gruyère and Parmesan for a more complex flavor profile.

No won ton wrappers? Phyllo dough works in a pinch, though the texture will differ slightly. Short on spinach? Fresh arugula or baby kale add a peppery contrast. The bell pepper can be omitted entirely if you prefer a simpler flavor profile, but it adds a pleasant crunch and vibrant color. For extra richness, stir 1 tbsp cream cheese into the egg mixture before assembling. The olive oil and butter sealing step is non-negotiable—it creates that signature golden crust. Use a pastry brush for even distribution, and don't skip the chilling step before sealing; it ensures the wrappers stay pliable and crisp during cooking.

Assembled egg bites keep 3 days in the fridge, sealed in an airtight container with parchment between layers to prevent sticking. For longer storage, freeze uncooked bites for up to 2 months—simply sous vide from frozen, adding 5 minutes to the cook time. Reheat cooked bites in the air fryer at 350°F for 3-4 minutes for maximum crispiness. The sous vide water bath can be reused for 2-3 batches if you maintain the same temperature, saving both time and water.

Step-by-step instructions for crispy-wonton cups with silky yolk magic

Master the sous vide technique for perfectly balanced texture—crispy wrappers and silky yolks every time.

In a medium bowl, whisk together the 6 whole Large Eggs, 0.5 cup Milk, 0.25 cup Heavy Cream, 0.5 tsp Salt, 0.25 tsp Black Pepper, and 0.25 tsp Garlic Powder until completely homogeneous. The mixture should be smooth with no visible streaks of egg white. I like to use a fork first to break up the yolks, then switch to a whisk for the final blend—this ensures even emulsification.

Next, fold in the 0.25 cup Fresh Spinach and 0.25 cup Red Bell Pepper using a silicone spatula. Be gentle to avoid incorporating air bubbles. The spinach should be finely chopped (about ¼-inch pieces) and the bell pepper diced into ⅛-inch cubes—this prevents texture inconsistencies in your egg bites. Set the mixture aside while you prepare the sous vide setup.

Fill a large pot with water and set it on a stovetop burner. Place a sous vide immersion circulator in the pot and turn it on to heat. Once the water reaches 170°F (the ideal temperature for egg bites—hot enough to set the eggs gently but not scramble them), you're ready to proceed. I use a 170°F target because it creates that signature custardy center while allowing the edges to set properly.

While the water heats, prepare your sous vide bags or containers. I recommend using 24 individual silicone bags (one per wonton wrapper) for even cooking. Divide the egg mixture evenly between them, using about ¼ cup per bag. This precise measurement ensures consistent results across all egg bites—no one bite should be denser or runnier than another.

Carefully seal each bag, removing as much air as possible to prevent expansion during cooking. Place the sealed bags into the 170°F water bath and cook for 1 hour. The gentle heat will transform the liquid egg into a silky, custard-like texture without overcooking. Here's the thing—don't peek or move the bags during cooking. The steady temperature is what creates that perfect balance of set and runny yolk.

After 1 hour, remove the bags from the water bath and let them cool slightly. The egg mixture should now have the consistency of thick pudding—it should hold its shape when gently spooned but still have a slight wobble in the center. If you poke it with a toothpick, it should come out clean but leave a slight resistance.

Preheat your oven to 375°F. Brush each wonton wrapper lightly with 1 tbsp Olive Oil and place them in a 12-cup muffin tin—press gently to form the cups. I use a small spoon to help shape them neatly into the tin. This step is crucial for achieving that crispy texture you're after—the oil helps create a golden-brown crust.

Once the wrappers are shaped, carefully spoon ¼ cup of the cooled egg mixture into each wonton cup. Sprinkle 2 tablespoons of Shredded Cheddar Cheese over each egg bite, then place the muffin tin on a baking sheet. Bake for 12-15 minutes until the wonton cups are golden brown and the cheese is bubbly and slightly melted. The edges should be crispy to the touch, while the centers remain soft and custardy.

Remove the egg bites from the oven and immediately dot each one with 1 tbsp Butter (divided evenly). Return the muffin tin to the oven for 2-3 minutes to allow the butter to melt and seep into the wonton cups, enhancing their crispiness. This final step is what elevates these from good to restaurant-quality—it adds a rich, buttery depth that balances the sharpness of the cheddar.

Let the egg bites cool for 5 minutes before serving. The contrast of crispy wonton cups with the silky egg centers and melted cheese is what makes these bites so irresistible. Serve warm, straight from the muffin tin, and watch them disappear!

Essential equipment for this dish

Sous Vide Circulator

Your most critical tool is a sous vide immersion circulator—I recommend the Anova Precision Cooker or Breville Joule for beginners. These maintain 170°F with ±0.1°F precision, essential for perfect egg bite texture. The Joule has built-in Bluetooth for remote monitoring, while the Anova is more budget-friendly. Avoid cheap circulators—they struggle with temperature fluctuations that can turn your yolks rubbery. 🌡️

Silicone Bags

Use 24 individual silicone sous vide bags (like VacSeal or Ziploc brand) for even cooking. These prevent expansion and allow easy sealing. I avoid reusable bags—they can develop odors over time. For assembly, divide your egg mixture into ¼ cup portions per bag. Remove as much air as possible before sealing to prevent water absorption during cooking.

Muffin Tin & Brush

A 12-cup muffin tin (preferably non-stick) is non-negotiable for crispy wonton cups. I use Wilton brand for its even heat distribution. Pair it with a pastry brush (like OXO Good Grips) to apply olive oil evenly to the wrappers. The brush ensures consistent crispiness—dipping wrappers in oil often leads to soggy spots. Keep a small bowl of water nearby to rinse the brush between coats.

Precision Thermometer

Invest in a dual-probe thermometer (such as the ThermoWorks Smoke) to monitor both your sous vide bath and egg bite internal temperature. The Smoke model tracks up to 4 zones simultaneously. For egg bites, aim for 160-165°F at the center—they'll continue cooking slightly when removed from heat. This prevents overcooking while ensuring food safety. Never rely on the circulator's display alone.

Air Fryer (Optional)

For reheating or extra crispiness, an air fryer (like Ninja Foodi or Cosori) is a game-changer. Set to 350°F for 3-4 minutes to revive any lost crispness. The Ninja Foodi has a dehydrate function that works perfectly for this. If you don't have one, a toaster oven at 375°F for 5-6 minutes delivers similar results. Avoid conventional ovens—they can overcook the delicate egg centers.

Storage Containers

Use glass airtight containers (like Pyrex or Rubbermaid) for storing cooked egg bites. The glass preserves texture better than plastic. Store in single layers with parchment paper between each to prevent sticking. For freezing uncooked bites, use quart-sized freezer bags—leave 1 inch headspace for expansion. Label with dates to track freshness. The containers should have snap-on lids for easy stacking in your fridge or freezer. 💫
