Cranberry Sausage Stuffing Casserole

The smell of sage and sausage browning in a cast iron skillet is my personal version of a holiday alarm clock, and it always pulls everyone into the kitchen before the coffee is even ready.

One Thanksgiving weekend, my sister walked into the kitchen still in her pajamas, took one bite of this casserole, and declared she was cancelling all future holiday plans that did not include it.

Ingredients

• 1 pound breakfast sausage, casing removed: Pork gives you the richest flavor but turkey works beautifully if you want something lighter.
• 1 medium onion, finely chopped and 2 celery stalks, diced: These two are the quiet backbone of every good stuffing and they soften into sweetness as they cook.
• 1 cup fresh or frozen cranberries: They burst in the oven and create little pockets of tangy brightness throughout the casserole.
• 6 cups cubed day old bread: French or sourdough are ideal because their sturdy texture soaks up custard without turning to mush.
• 1 1/2 cups whole milk and 1 cup heavy cream: This combination makes the custard silky and indulgent.
• 6 large eggs: The structural glue that holds everything together in a tender, puffy bake.
• 1 cup shredded sharp cheddar and 1/4 cup grated Parmesan: Sharp cheddar melts into gooey strands while Parmesan adds a salty, golden crust on top.
• 2 tablespoons fresh parsley, 2 teaspoons dried sage, and 1 teaspoon dried thyme: Sage is the soul of this dish and thyme adds an earthy warmth that ties it all together.
• 3/4 teaspoon kosher salt, 1/2 teaspoon black pepper, and 1/4 teaspoon crushed red pepper flakes: The red pepper flakes are optional but they add a gentle hum of heat that balances the cranberries.
• Butter or nonstick spray for greasing: Do not skip this unless you enjoy chiseling casserole off your baking dish.

Instructions

Preheat and prepare the dish:

Set your oven to 350 degrees F and generously grease a 9x13 inch baking dish with butter. Go ahead and butter it a little more than you think you need.

Brown the sausage:

Crumble the sausage into a large skillet over medium heat and cook until deeply browned and cooked through, about 6 to 8 minutes. Transfer it to a plate with a slotted spoon and try not to eat too much of it straight from the pan.

Soften the aromatics:

In the same skillet with all those lovely sausage drippings, sauté the onion and celery until they are soft and fragrant, about 5 minutes. Those browned bits on the bottom of the pan are pure flavor so let them work into the vegetables.

Build the filling:

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 you need to because it is the best way to make sure everything is evenly distributed.

Make the custard:

Whisk the milk, cream, and eggs together in a separate bowl until smooth, then stir in the cheddar and Parmesan. Pour this luscious mixture over the bread and toss gently until every cube is moistened and eager to soak it all up.

Assemble and rest:

Transfer everything to your prepared baking dish, spread it out evenly, and then walk away for 10 minutes. That resting time lets the bread drink in the custard and makes all the difference in the final texture.

Bake until golden:

Slide the dish into the oven uncovered and bake for 45 to 50 minutes until the top is deeply golden and the center is set with just a slight wobble. Let it cool for a few minutes before serving because molten custard will burn your tongue and test your patience.

Pin it

There is something deeply satisfying about pulling a golden, bubbling casserole from the oven while the house is still quiet and the only sound is the coffee maker gurgling in the background.

Making It Your Own

Dried cranberries work if fresh ones are out of season but reduce the amount to 2/3 cup and soak them in hot water for 10 minutes first so they plump up and do not steal moisture from the custard.

Vegetarian Swaps

Omitting the sausage is easy and you can replace it with a generous handful of sautéed mushrooms or cooked lentils to keep the dish hearty and satisfying without the meat.

Serving and Storing

This casserole reheats beautifully covered in foil at 350 degrees F for about 15 minutes, making it just as good on day two when the flavors have had time to mingle and settle.

• A simple green salad with a bright vinaigrette cuts through the richness perfectly.
• Fresh fruit on the side adds a welcome burst of freshness to each plate.
• Leftovers keep well covered in the refrigerator for up to 3 days and make an excellent lunch you will actually look forward to.

Pin it

This casserole has a way of turning an ordinary weekend morning into something that feels like a celebration, and that is the highest compliment any breakfast can earn.

Recipe FAQs

→ Can I assemble this casserole the night before?

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 it goes in cold.

→ Can I use dried cranberries instead of fresh?

Absolutely. If using dried cranberries, reduce the amount to 2/3 cup 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?

Day-old French bread or sourdough works best because the cubes hold their shape and absorb the custard without turning mushy. Make sure the bread is at least a day old so it's slightly stale and firm enough for cubing.

→ 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 — if it comes out clean with no liquid egg mixture, it's ready. This typically takes 45–50 minutes at 350°F.

→ Can I make a vegetarian version?

Yes, simply omit the sausage and replace it with sautéed mushrooms or cooked lentils for substance and texture. Adjust the salt accordingly, as sausage adds seasoning to the overall dish.

→ How should I store and reheat leftovers?

Store leftovers covered 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.
