Cranberry Sausage Stuffing Casserole

Thanksgiving morning, seven people crammed into my kitchen, and someone had already eaten the pastries I bought. That crisis birthed this casserole: I grabbed leftover stuffing components from the fridge, browned some sausage, tossed in a handful of cranberries, and poured custard over the whole thing. It worked so well that now my family refuses to let me make anything else for holiday breakfast.

My sister called it a deconstructed Thanksgiving dinner in breakfast form, and honestly she nailed it. The first time I served it, my brother in law went back for thirds before anyone else finished firsts.

Ingredients

• 1 pound breakfast sausage, casing removed: Pork gives you more fat and flavor, but turkey sausage works beautifully if that is what you have.
• 1 medium onion, finely chopped: Yellow or white onion both work, just make sure the pieces are small so they melt into the casserole.
• 2 celery stalks, diced: Celery and onion are the backbone of any good stuffing, do not skip them.
• 1 cup fresh or frozen cranberries: These little bursts of tartness are what make this dish special.
• 6 cups cubed day old bread: Sourdough or French bread holds up best to the custard without turning to mush.
• 1 1/2 cups whole milk and 1 cup heavy cream: The combination gives you a custard that is rich but not overwhelmingly heavy.
• 6 large eggs: This is the glue that holds everything together in a creamy, satisfying layer.
• 1 cup shredded sharp cheddar and 1/4 cup grated Parmesan: Sharp cheddar brings tang and Parmesan adds a salty, savory finish on top.
• 2 tablespoons fresh parsley, 2 teaspoons dried sage, 1 teaspoon dried thyme: These three herbs make the whole kitchen smell like a holiday.
• 3/4 teaspoon kosher salt, 1/2 teaspoon black pepper, 1/4 teaspoon red pepper flakes: The flakes are optional but they add a gentle warmth that balances the cranberries.
• Butter or nonstick spray for greasing: Do not be shy with this, you want a clean release.

Instructions

Get the oven ready:

Preheat your oven to 350 degrees and grease a 9 by 13 baking dish generously with butter. Give the dish a good coating because nothing is sadder than a casserole that sticks.

Brown the sausage:

Crumble the sausage into a large skillet over medium heat and cook until browned and cooked through, about 6 to 8 minutes. Transfer it to a plate with a slotted spoon and leave those flavorful drippings behind.

Soften the aromatics:

In the same skillet, cook the onion and celery in the residual sausage fat until they are soft and translucent, about 5 minutes. This is where the kitchen starts smelling incredible.

Build the base:

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. Use your hands if needed to get everything evenly distributed.

Make the custard:

Whisk together the milk, cream, and eggs in a separate bowl until smooth, then stir in both cheeses. Pour this mixture over the bread mixture and gently toss until every piece of bread is moistened.

Let it rest and bake:

Transfer everything to the prepared dish, spread it evenly, and let it sit for 10 minutes so the bread soaks up all that custard. Bake uncovered for 45 to 50 minutes until the top is golden and the center is set.

The year I brought this to a potluck brunch, three separate people asked for the recipe before they even finished their plates. One friend texted me at midnight on Christmas Eve to confirm the measurements.

Make It Your Own

This recipe is forgiving in the best way. You can swap the sausage for sautéed mushrooms or cooked lentils if you want a vegetarian version, and it still tastes like something worth waking up for.

Leftovers and Reheating

Covered tightly in the fridge, this casserole stays delicious for up to three days. Reheat individual portions in the microwave for about 90 seconds, or warm the whole dish covered with foil at 325 degrees for 20 minutes.

Serving Suggestions

A simple green salad with vinaigrette alongside this casserole keeps things balanced, or a platter of fresh fruit works too. Here are a few final thoughts to keep in mind.

• Let the casserole cool for at least 10 minutes before slicing so the pieces hold together.
• Extra parsley on top is not just garnish, it adds freshness that cuts through the richness.
• This reheats so well that making the full batch is always worth it even for a smaller crowd.

Recipe FAQs

→ Can I assemble this casserole the night before?

Yes, you can prepare the casserole up to the baking step, 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 it goes in cold.

→ Can I use dried cranberries instead of fresh?

Absolutely. Reduce the amount to 2/3 cup and soak the dried cranberries in hot water for 10 minutes, then drain well before adding them. This helps rehydrate them so they blend nicely into the casserole without drawing too much moisture from the custard.

→ What type of bread works best for this casserole?

Day-old French bread or sourdough are excellent choices because their sturdy texture holds up well to the custard without turning mushy. Cut the bread into even cubes and let it sit uncovered for several hours or overnight to dry out slightly for the best results.

→ 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 insert a knife into the middle — it should come out clean with no liquid egg mixture. The internal temperature should reach 160°F (71°C) for food safety.

→ Can I make this without meat for a vegetarian version?

Yes, simply omit the sausage and add sautéed mushrooms or cooked lentils for substance and texture. You may want to increase the seasonings slightly, as sausage contributes flavor through its fat and spices.

→ How should I store and reheat leftovers?

Store leftover casserole covered in the refrigerator for up to 3 days. Reheat individual portions in the microwave for 1–2 minutes, or warm the whole dish in a 325°F (165°C) oven covered with foil for about 20 minutes until heated through.
