Cranberry Sausage Breakfast Casserole

The kitchen smelled like Thanksgiving had collided with a Sunday morning, and honestly, that is exactly what happened the weekend I threw leftover stuffing components into a casserole dish with sausage and eggs. Cranberries were bubbling in the corner of the skillet, the bread was soaking up every bit of that savory, creamy custard, and I realized I had stumbled onto something worth repeating every holiday season. This Cranberry Sausage Stuffing Breakfast Casserole is the kind of dish that makes people linger at the table long after their plates are clean.

I made this for eight friends the morning after a particularly late holiday party, and even the people who claimed they never eat breakfast came back for seconds. Someone ate a third helping standing at the kitchen counter while holding the serving spatula like a microphone, retelling the story of the night before. That casserole disappeared in under twenty minutes, and I have not been allowed to host a brunch without it since.

Ingredients

• 1 lb (450 g) breakfast sausage, casings removed: Mild gives you a gentle, familiar flavor, but spicy sausage turns this into something with a real kick that cuts through the richness beautifully.
• 1 medium onion, diced: Yellow or white onion works, and dicing it small ensures it melts into the filling without overpowering anyone bite.
• 2 celery stalks, diced: This is the quiet backbone of the flavor, adding just enough earthy crunch before it softens in the skillet.
• 1 cup dried cranberries: They plump slightly during baking and create little pockets of tart sweetness that surprise you in the best way.
• 2 tablespoons fresh parsley, chopped: Fold it in at the end so its brightness actually comes through instead of getting lost in the bake.
• 8 cups (about 300 g) day-old bread, cut into 1-inch cubes: Sourdough is my favorite because its natural tang plays so well with the sausage, but any sturdy country bread holds up perfectly.
• 1 and 1/2 cups (360 ml) whole milk: Whole milk gives the custard body without making it heavy, so do not be tempted to swap in skim.
• 1 cup (240 ml) heavy cream: This is what turns the texture from a standard strata into something truly luxurious and silky.
• 6 large eggs: They bind everything together and create that golden, puffy top that makes the dish look as good as it tastes.
• 1 cup (100 g) shredded cheddar cheese: Sharp cheddar adds a tangy depth that mild cheese simply cannot match here.
• 2 tablespoons unsalted butter, melted: Mixed into the custard, it enriches every bite and helps achieve that gorgeous golden crust on top.
• 1 teaspoon dried sage: One teaspoon is all you need to give the whole dish that unmistakable stuffing aroma.
• 1 teaspoon dried thyme: Thyme and sage together are the reason this tastes like a holiday table in casserole form.
• 1 teaspoon salt: The sausage adds some salt already, so one teaspoon in the custard keeps things balanced without going over.
• 1/2 teaspoon ground black pepper: Freshly cracked is always better, adding a subtle warmth that ties all the flavors together.

Instructions

Prepare the oven and dish:

Preheat your oven to 350 degrees Fahrenheit and grease a 9 by 13 inch baking dish with butter, making sure to get into the corners so nothing sticks later.

Brown the sausage:

Cook the sausage in a large skillet over medium heat, breaking it into crumbles as it browns, which should take about six to eight minutes until you see no pink remaining. Transfer the sausage to a plate but leave those flavorful drippings right where they are.

Soften the aromatics:

Toss the diced onion and celery into the same skillet and saute them in the residual sausage fat until they are soft and translucent, about five minutes, then pull the pan off the heat.

Combine the filling:

In a large mixing bowl, toss together the bread cubes, cooked sausage, sauteed onion and celery, dried cranberries, parsley, sage, thyme, salt, and pepper until everything is evenly distributed.

Whisk the custard:

In a separate bowl, whisk the eggs, milk, heavy cream, and melted butter until smooth and fully combined, with no streaks of yolk visible.

Marry it all together:

Pour the egg mixture over the bread mixture and toss gently until every cube is coated and soaking up that creamy liquid, then fold in the shredded cheddar cheese.

Assemble and rest:

Transfer everything into your prepared baking dish, pressing gently to create an even layer, and at this point you can cover and refrigerate it overnight if you want to get ahead for the morning.

Bake until golden:

Bake uncovered for forty-five to fifty minutes until the top is a deep golden brown and the center of the custard is fully set with no jiggle remaining when you gently shake the dish.

Rest and serve:

Let the casserole rest for ten minutes before cutting into it so the custard has time to settle and hold its shape, then garnish with extra parsley if you like.

Save

There is something about pulling a golden, bubbling casserole out of the oven on a cold morning that makes the whole house feel like the place everyone wants to be. It turns a regular weekend into an event without any extra effort.

Make It Your Own

Chopped apples folded in with the cranberries add a layer of crunch and sweetness that works surprisingly well with the savory sausage. Toasted pecans scattered over the top before baking give the whole dish a nutty, crispy finish that people will ask about every time you serve it. You can even swap the cheddar for Gruyere if you want to lean into a richer, more sophisticated flavor.

The Overnight Strategy

Assembling everything the night before is not just a convenience, it actually improves the texture because the bread has hours to absorb every bit of that eggy custard. Cover the dish tightly with foil and tuck it into the fridge, then all you have to do in the morning is slide it into the oven and wait for the smell to wake everyone up. This is the reason this recipe has become my go-to for holiday mornings when I want to enjoy the day instead of standing over the stove.

Serving and Storage

Leftovers reheat beautifully in a 325 degree oven for about fifteen minutes, and they taste almost as good as the first day if you cover the dish with foil to keep the top from drying out. A dash of hot sauce on top is nonnegotiable in my house, and extra cheese never hurt anyone. This casserole is best enjoyed within three days, though it rarely lasts that long.

• Let the casserole rest for the full ten minutes so every slice comes out clean and holds its shape on the plate.
• A simple green salad or fresh fruit on the side balances the richness and makes it feel like a complete meal.
• Always check that the center is fully set before you pull it from the oven because a wet middle will ruin the whole texture.

Save

This casserole is a reminder that the best recipes are the ones that bring people to the table and keep them there, laughing and reaching for just one more serving. Make it once, and it will become part of your tradition too.

Recipe Questions

→ Can I assemble this casserole the night before baking?

Yes, you can prepare the entire casserole up to the point of baking, cover it tightly, and refrigerate overnight. In the morning, simply pop it in the oven and add a few extra minutes to the baking time if it goes in cold.

→ What type of bread works best for this dish?

Sturdy, day-old bread works best. Sourdough adds wonderful tang and texture, but French bread or a country loaf also work beautifully. Avoid very soft sandwich bread, as it can become too mushy when soaked in the custard.

→ Can I use fresh cranberries instead of dried?

Dried cranberries are recommended because they blend seamlessly into the casserole without releasing excess moisture. Fresh cranberries would add too much liquid and tartness. If you only have fresh, consider sweetening and cooking them down first.

→ How do I know when the casserole is fully cooked?

The casserole is done when the top is golden brown and the center is set. You can test by inserting a knife into the middle—if it comes out clean and the custard doesn't jiggle, it's ready. This typically takes 45 to 50 minutes at 350°F.

→ Can I substitute a different meat for the breakfast sausage?

Absolutely. Ground turkey sausage, chorizo, or even crumbled bacon would work well in place of traditional pork breakfast sausage. Keep in mind that leaner meats may produce less drippings for sautéing the vegetables.

→ How should I store and reheat leftovers?

Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat individual portions in the microwave for about 60 seconds, or warm the whole dish in a 325°F oven until heated through. It also freezes well for up to 2 months.
