What Ingredients You Will Need

This Cozy Christmas Breakfast Casserole uses simple, wholesome ingredients to deliver bold flavor and satisfying texture without the fuss. Most of these are pantry staples, with a few fresh touches that bring it all to life.

• Dried Bread Cubes: About 6 cups (approximately 170g), preferably day-old or slightly stale for best soaking.
• Breakfast Sausage: 1 pound (450g), pork or turkey, cooked and crumbled (I like Johnsonville for consistent flavor).
• Eggs: 8 large, room temperature (helps with even mixing and fluffy texture).
• Cottage Cheese: 1 cup (240ml), small-curd recommended for smoothness (I use Daisy brand).
• Milk: 1 ½ cups (360ml), whole or 2% for creaminess (dairy-free milk works too!).
• Shredded Cheddar Cheese: 2 cups (200g), sharp or mild based on preference.
• Onion: ½ cup finely chopped, adds a subtle sweetness.
• Green Bell Pepper: ½ cup finely chopped, optional but adds a nice color and bite.
• Garlic Powder: 1 teaspoon, for a gentle, savory note.
• Dried Italian Herbs: 1 teaspoon, for a festive herbaceous touch.
• Salt & Pepper: To taste, usually about 1 teaspoon salt and ½ teaspoon freshly ground pepper.
• Butter: 2 tablespoons, for greasing the baking dish and adding richness.

If you want to swap out the sausage, cooked bacon or ham work beautifully. For a gluten-free option, use gluten-free bread or substitute with cubed cooked potatoes. In summer, you might add fresh diced tomatoes or swap the bell pepper for roasted red peppers. Honestly, the beauty of this recipe lies in its flexibility, making it a perfect canvas for whatever you have on hand.

Equipment Needed

• 9×13-inch Baking Dish: A sturdy glass or ceramic dish works best. I’ve tried metal pans, but glass gives a more even, gentle bake.
• Mixing Bowls: One large bowl for combining eggs and dairy, and another for mixing cooked sausage and veggies.
• Whisk or Fork: For beating eggs and blending cottage cheese evenly.
• Skillet: To cook the sausage and sauté onions and peppers. A non-stick pan is ideal for easy cleanup.
• Measuring Cups and Spoons: Precision helps with consistent results, especially with eggs and dairy.
• Spatula or Wooden Spoon: For mixing everything together.

If you don’t have a skillet, a microwave-safe bowl can steam the veggies, but the flavor won’t be quite the same (I learned that the hard way!). For budget-friendly options, baking dishes from thrift stores or discount retailers work just fine—just make sure they’re oven-safe.

Preparation Method

1. Prep Ingredients (10 minutes): Preheat your oven to 350°F (175°C). Grease your 9×13-inch baking dish with butter. Cube your dried bread into roughly 1-inch pieces. Cook the breakfast sausage in a skillet over medium heat until fully browned, about 7-8 minutes. Remove from heat and drain excess fat. Sauté the chopped onion and bell pepper in the same skillet for 3-4 minutes until softened.
2. Mix Wet Ingredients (5 minutes): In a large mixing bowl, whisk together 8 large eggs, 1 cup cottage cheese, and 1 ½ cups milk until smooth. Add garlic powder, dried Italian herbs, salt, and pepper. Whisk again until all combined and slightly frothy—this helps with the casserole’s fluffy texture.
3. Combine Components (5 minutes): In a very large bowl, combine the bread cubes, cooked sausage, sautéed veggies, and 2 cups shredded cheddar cheese. Pour the egg mixture over the top. Use a spatula to gently fold everything together, making sure all bread pieces soak evenly. Let it sit for 5 minutes—this gives the bread time to absorb the custard without getting soggy.
4. Transfer and Bake (45-50 minutes): Pour the mixture evenly into your greased baking dish. Spread it out gently with a spatula. Bake uncovered in the preheated oven for 45 to 50 minutes, until the top is golden brown and a knife inserted in the center comes out clean. The edges will be slightly crispy—the very best part!
5. Rest and Serve (10 minutes): Remove the casserole from the oven and let it rest for about 10 minutes before slicing. This helps it set and makes serving easier. You’ll notice the aroma intensifies during this time, just begging to be devoured.

If you find the top browning too quickly, cover loosely with foil halfway through baking. Also, make sure your eggs are at room temperature to prevent a rubbery texture. Trust me, these little tips make all the difference!

Cooking Tips & Techniques

One pro tip I learned early on is to use day-old or slightly stale bread. Fresh bread can turn the casserole into a soggy mess, but dried bread soaks up the custard perfectly, creating that ideal balance between soft and firm. Also, don’t skip the resting time after baking; it’s tempting to dig right in, but patience pays off with cleaner slices and better texture.

When cooking the sausage, drain the excess fat well to avoid a greasy casserole. If you’re using leaner meats like turkey sausage, adding a little butter to the veggies while sautéing helps keep things flavorful and moist. I also recommend stirring the egg mixture gently—overmixing can cause the eggs to toughen during baking.

Timing is crucial; if you prep everything the night before, store the assembled casserole covered in the fridge and bake it fresh the next morning. This way, the flavors meld, and you’ll have a stress-free holiday start. Multitasking is key—while the sausage cooks, chop veggies and prep bread cubes to save time.

Lastly, feel free to sprinkle extra cheese on top during the last 10 minutes if you like a bubbly, golden crust. I’ve done that many a Christmas morning, and it’s always a crowd-pleaser.

Variations & Adaptations

This Cozy Christmas Breakfast Casserole is wonderfully adaptable, so you can tweak it to fit your family’s tastes and dietary needs.

• Vegetarian Version: Swap sausage for sautéed mushrooms, spinach, and sun-dried tomatoes for a hearty veggie-packed casserole.
• Gluten-Free: Use gluten-free bread cubes or substitute with roasted diced potatoes or sweet potatoes for a different but delicious texture.
• Seasonal Flavor Twists: Add diced apples and a pinch of cinnamon for a sweet-savory holiday vibe, or include chopped fresh herbs like rosemary and thyme for an herbal kick.
• Dairy-Free: Replace milk and cottage cheese with coconut or almond milk and use dairy-free cheese alternatives. I’ve tried this version and, honestly, it’s surprisingly tasty.
• Make-Ahead Option: Assemble the casserole the night before and refrigerate. Bake fresh in the morning, adding 10 minutes to the baking time if chilled.

Personally, I once added a handful of chopped jalapeños for a spicy surprise, which my family loved. Don’t be afraid to get creative; this casserole is a forgiving base for all sorts of festive flavors.

Serving & Storage Suggestions

Serve this casserole warm, ideally fresh from the oven with a sprinkle of fresh parsley or chives for color. It pairs beautifully with a side of mixed fruit or a simple arugula salad dressed in lemon vinaigrette to balance the richness. For drinks, a hot cup of coffee or mulled cider really sets the mood.

Store leftovers covered tightly in the fridge for up to 3 days. Reheat individual portions in the microwave for about 1-2 minutes or rewarm the whole dish in a 325°F (165°C) oven for 15-20 minutes, covered with foil to avoid drying out. You’ll find the flavors develop a bit overnight, making for a tasty breakfast the next day.

For longer storage, freeze portions wrapped in foil and plastic wrap for up to 2 months. Thaw overnight in the fridge before reheating. Just so you know, the texture might be slightly softer after freezing but still delicious and comforting.
