Ingredients for christmas morning egg bake

Basic pantry staples and festive flavors create the perfect Christmas morning centerpiece.

The sausage makes this dish hearty enough for a crowd. Kirkland Signature or any high-quality Italian sausage with good marbling works best—avoid the lean versions. Pre-sliced rounds cook evenly and save time. For extra flavor, Costco or Whole Foods carry excellent options. The eggs should be large and fresh, as they create the velvety custard base. Room temperature eggs blend more smoothly, so take them out 30 minutes before baking. The cheese is non-negotiable—sharp cheddar melts beautifully and adds that perfect tangy bite that balances the richness of the sausage.

No Italian sausage? Breakfast sausage or even pre-cooked bacon works in a pinch, though the flavor profile changes. The heavy cream can be swapped for more milk if you're watching calories, but trust me on the full-fat version—it makes all the difference. Fresh herbs are ideal, but dried chives or parsley at one-third the amount will do. For a dairy-free option, substitute the milk with unsweetened almond milk and use a dairy-free cheese alternative. The garlic can be omitted if you're not a fan, but it adds that subtle depth that makes this dish restaurant-quality.

This bake reheats beautifully—make extra for leftovers. Store in an airtight container in the fridge for up to 3 days, though it's best enjoyed fresh. For freezing, portion into individual servings and freeze for up to 3 months. When reheating, cover with foil and warm at 350°F for 15-20 minutes. The skillet should be cast iron for even heat distribution, but any oven-safe skillet will work. Garnish with fresh herbs right before serving to keep them vibrant and add that festive pop of color.

Step-by-step instructions for Christmas morning egg bake

This one-pan breakfast comes together quickly with minimal prep and maximum flavor.

Heat a large oven-safe skillet over medium-high heat. Add the 2 tablespoons extra-virgin olive oil and swirl to coat. Add the 1.5 lb Kirkland Signature Creamy Italian Sausage (sliced into rounds) and cook for 5-6 minutes until browned on all sides, breaking up any large pieces with a wooden spoon.

Add the 4 cloves minced garlic cloves and cook for another 30 seconds until fragrant. Remove the skillet from heat and let it cool slightly—this prevents the custard from curdling when we mix it in. The sausage should be golden brown and the garlic should smell deeply aromatic without burning.

In a large bowl, whisk together the 12 whole Large Eggs, 2 cups Milk, 0.5 cup Heavy Cream, 1.5 tsp Salt, and 1 tsp Black Pepper until fully combined. The mixture should be smooth with no streaks of egg white remaining.

In a separate small bowl, whisk together the 0.5 cup All-Purpose Flour and 2 cups Sharp Cheddar Cheese until the cheese is finely crumbled and evenly distributed. Gradually pour the flour-cheese mixture into the egg mixture while whisking constantly to create a smooth, thick custard. This step ensures the finished bake has a creamy texture with no lumps.

Return the skillet with cooked sausage and garlic to the stovetop over low heat. Add the 2 tablespoons Butter and let it melt completely. Pour the custard mixture evenly over the sausage, tilting the pan to distribute it completely. Sprinkle the 0.25 cup Fresh Chives and 0.25 cup Fresh Parsley evenly over the top.

Here's the thing—don't stir after pouring. The sausage should be partially submerged in the custard, and that's exactly how we want it. The residual heat from the skillet will help set the custard slightly before it goes into the oven, creating a golden crust on top.

Transfer the skillet to a 375°F preheated oven. Bake for 30-35 minutes until the top is golden brown and the custard is set but still slightly jiggly in the center. You'll know it's ready when the edges pull away from the skillet and the center doesn't shake excessively when gently moved.

I like to check for doneness by inserting a knife near the center—it should come out clean with just a slight coating of custard. If it's still too wet, return it to the oven for another 2-3 minutes. The cheese should be melted throughout, and the sausage fully heated through.

Remove the skillet from the oven and let it rest for 5 minutes before serving. This resting period allows the custard to set slightly and makes it easier to slice. Use a large spatula to divide the bake into 8 equal portions for serving.

Garnish each portion with an extra sprinkle of Sharp Cheddar Cheese and a pinch of freshly ground Black Pepper. The combination of creamy custard, savory sausage, and sharp cheese creates a perfect balance of flavors that's ideal for a festive morning. Serve immediately while still warm for the best texture and flavor experience.

Flavor customization for this dish

Cheesy Variations

Swap the sharp cheddar for Monterey Jack if you prefer a milder, creamier cheese—it melts beautifully and pairs perfectly with the sausage. For a tangy twist, mix ½ cup sharp cheddar with ½ cup pepper jack for a subtle heat that wakes up every bite. I’ve also tested Gruyère here, and it adds a nutty depth that elevates the dish to gourmet status. 🧀

Protein Swaps

Craving something different? Replace the sausage with diced ham for a sweeter, more traditional holiday flavor—just reduce the baking time by 5 minutes since ham cooks faster. For a vegetarian option, fold ½ cup sautéed mushrooms and ½ cup spinach into the custard before baking. I’ve even used smoked salmon for a brunch-worthy twist, omitting the garlic to avoid overpowering the delicate fish flavor.

Herb & Spice Boosts

Add ½ teaspoon smoked paprika to the custard for a subtle smokiness that pairs beautifully with the sausage. Fresh thyme leaves scattered on top before baking add an earthy aroma that’s perfect for Christmas. For a citrusy kick, zest 1 lemon and fold it into the custard—it brightens the richness of the cheese and eggs. 🌿

Sweet & Savory Fusion

Believe it or not, this bake works surprisingly well with a touch of sweetness! Stir 2 tablespoons maple syrup into the custard for a caramelized finish, or top with sautéed apples before baking. I’ve also tried adding ½ cup dried cranberries to the custard for a festive pop of color and tartness that balances the savory sausage. Trust me, it’s a crowd-pleaser!

Dairy-Free Adaptations

For a dairy-free version, replace the milk and heavy cream with unsweetened almond milk and add 1 tablespoon cornstarch to the custard to help it set. Use dairy-free sharp cheddar (like Violife) and ensure your sausage is also dairy-free. The texture stays creamy, though slightly lighter—perfect for guests with dietary restrictions without sacrificing flavor. 🌱
