Cranberry Sausage Stuffing Casserole

The morning after Thanksgiving, my kitchen always smells like leftovers and regret, but one year I decided to change that by throwing everything savory into a casserole dish and calling it breakfast. Cranberries from the sauce nobody touched, leftover stuffing croutons, and a roll of breakfast sausage from the back of the freezer somehow became the most requested dish at every holiday gathering since. It is chaotic, golden, and unapologetically indulgent in the best way.

My sister walked into the kitchen the first time I made this, looked at the cranberries sitting next to the sausage, and told me I had finally lost it. She ate three helpings and now texts me every December asking if I am making that cranberry thing again.

Ingredients

• 1 pound breakfast sausage, casing removed: Pork brings more fat and flavor, but turkey sausage works beautifully if that is what you have on hand.
• 1 medium onion, finely chopped: Onion melts into the casserole and creates a sweet base that ties the savory and tart elements together.
• 2 celery stalks, diced: Celery adds a quiet crunch and freshness that keeps the dish from feeling too heavy.
• 1 cup fresh or frozen cranberries: These little bursts of tartness are the surprise star, and frozen cranberries work perfectly without thawing.
• 6 cups cubed day old bread: French or sourdough bread stands up to the custard without turning to mush, and day old bread absorbs flavor better.
• 1 1/2 cups whole milk: Whole milk creates a silky custard, and lower fat milk will leave you with a thinner, less satisfying texture.
• 1 cup heavy cream: This is what makes the casserole feel like a celebration rather than just breakfast.
• 6 large eggs: Eggs bind everything together into a cohesive, sliceable casserole that holds its shape.
• 1 cup shredded sharp cheddar cheese: Sharp cheddar gives you a pronounced cheese flavor without needing to use an excessive amount.
• 1/4 cup grated Parmesan cheese (optional): A dusting of Parmesan on top creates a salty, golden crust that is absolutely worth the extra step.
• 2 tablespoons chopped fresh parsley: Fresh parsley at the end brightens everything and makes the dish look as good as it tastes.
• 2 teaspoons dried sage: Sage is the soul of any stuffing inspired dish and immediately makes your kitchen smell like a holiday.
• 1 teaspoon dried thyme: Thyme adds an earthy depth that rounds out the herbs without overpowering anything.
• 3/4 teaspoon kosher salt: Proper seasoning is critical here because bread and potatoes can absorb surprising amounts of salt.
• 1/2 teaspoon ground black pepper: Freshly ground pepper adds a gentle warmth that complements the sausage beautifully.
• 1/4 teaspoon crushed red pepper flakes (optional): Just a pinch wakes up the whole dish without making it spicy.
• Butter or nonstick spray for greasing: Butter adds flavor to the edges of the casserole while preventing sticking.

Instructions

Preheat and prepare the dish:

Set your oven to 350 degrees F and generously grease a 9 by 13 inch baking dish with butter, making sure to coat the corners where sticking loves to happen.

Brown the sausage:

Crumble the sausage into a large skillet over medium heat and cook until fully browned and no pink remains, about 6 to 8 minutes, then transfer it to a plate with a slotted spoon.

Soften the aromatics:

In the same skillet with those delicious sausage drippings, cook the onion and celery until softened and fragrant, about 5 minutes, then remove from heat.

Build the base mixture:

In a large bowl, toss together the cubed bread, cooked sausage, sautéed onion and celery, cranberries, parsley, sage, thyme, salt, pepper, and red pepper flakes until evenly distributed.

Whisk the custard:

In a separate bowl, whisk the milk, cream, and eggs until smooth, then stir in the shredded cheddar and Parmesan if you are using it.

Combine and rest:

Pour the egg mixture over the bread mixture and gently toss until everything is evenly moistened, then transfer to your prepared dish and let it sit for 10 minutes so the bread can drink up all that custard.

Bake until golden:

Bake uncovered for 45 to 50 minutes until the top is deeply golden and the center is set, then let it rest for a few minutes before slicing and serving with extra parsley on top.

Pin It

The year I brought this to a friends holiday potluck, it disappeared before the cinnamon rolls did, and someone actually asked for the recipe on a napkin.

Making It Your Own

Dried cranberries work in a pinch but soak them in hot water for about 10 minutes and drain well first, otherwise they steal moisture from the custard and turn chewy. If fresh cranberries are available, use the full cup and do not thaw frozen ones before adding them.

Vegetarian Swaps That Actually Work

Leaving out the sausage does not mean leaving out the satisfaction, and sautéed mushrooms or cooked lentils provide both substance and a savory depth that pairs just as well with the cranberries. Add an extra pinch of smoked paprika to whatever you substitute and nobody will feel like they are missing anything.

What to Serve Alongside

This casserole is rich enough to stand on its own but truly shines next to something fresh and light that balances the plate.

• A simple arugula salad with lemon vinaigrette cuts through the richness perfectly.
• Fresh fruit like orange slices or grapes bring brightness to each bite.
• A cup of hot coffee or spiced cider is the only beverage you need.

Some dishes feed people, and this one brings them to the table laughing and reaching for seconds before the first round is even finished. That is all you can really ask of a recipe.

Recipe Questions

→ Can I assemble this casserole the night before baking?

Yes, you can fully assemble the casserole, cover it tightly, and refrigerate overnight. In the morning, let it sit at room temperature for about 20 minutes while the oven preheats, then bake as directed. You may need to add 5–10 extra minutes of baking time if going straight from the fridge.

→ Can I use dried cranberries instead of fresh?

Absolutely. Reduce the amount to 2/3 cup of dried cranberries and soak them in hot water for about 10 minutes before draining and adding to the mixture. This helps rehydrate them so they blend nicely into the casserole.

→ What type of bread works best for this dish?

Day-old French bread or sourdough works best because it holds its texture when soaked in the custard. Avoid soft sandwich bread, which can become too mushy. Cube the bread into roughly 1-inch pieces and let it stale overnight for optimal absorption.

→ How do I make this vegetarian?

Omit the sausage and replace it with sautéed mushrooms or cooked lentils for substance and texture. You may want to add an extra pinch of sage or smoked paprika to compensate for the flavor the sausage would typically contribute.

→ 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 covered with foil for 15–20 minutes until heated through.

→ Can I freeze this casserole?

Yes, you can freeze it either before or after baking. If freezing before baking, assemble in a foil pan, wrap tightly, and freeze for up to 2 months. Thaw overnight in the fridge before baking. If freezing after baking, portion into servings, wrap well, and freeze for up to 1 month.
