Sourdough Stuffing: The Best Thanksgiving Side Dish

Stuffing is the side dish that wins Thanksgiving — and sourdough makes it dramatically better than supermarket cubed bread. The structure holds, the flavor is deeper, and the crust gives texture you can't get any other way.

The recipe

For one large casserole (serves 10):

• 1.2 kg day-old sourdough, cubed (about 16 cups)
• 1 large yellow onion, diced
• 4 ribs celery, diced
• 6 tbsp butter
• 4 cloves garlic, minced
• 2 tbsp fresh sage, chopped
• 2 tbsp fresh thyme leaves
• 2 tbsp fresh parsley, chopped
• 1 tsp salt
• ½ tsp black pepper
• 4 cups good chicken or turkey broth
• 3 large eggs
• 1 lb bulk sausage (optional but recommended)

Method

Dry the bread

Cube the bread into ¾-inch pieces. Spread on two sheet pans. Bake at 250°F for 30 minutes, stirring halfway, until completely dry. This is essential — wet cubes make mushy stuffing.

Cook the aromatics

In a large skillet, cook the sausage (if using) until browned. Remove and set aside.

In the same pan, melt butter over medium heat. Add onion and celery. Cook 8 minutes until soft.

Add garlic and herbs. Cook 1 minute more.

Combine

In a very large bowl: dried bread cubes + cooked vegetables + sausage.

In a separate bowl: whisk broth and eggs together. Pour over the bread. Toss gently to coat. The bread should be moist but not soggy.

Bake

Transfer to a buttered 9×13 baking dish. Cover with foil.

Bake at 375°F:

• Covered for 30 minutes
• Uncovered for another 20–25 minutes until the top is crisp and golden

Inside the bird vs. outside

Inside the turkey ("dressing the bird") — picks up turkey flavor, but creates food safety concerns. Stuffing must reach 165°F internally, which often means overcooking the turkey.

Outside in a casserole — safer, more reliable, more crispy edges. This is the modern preferred method.

If you want some inside: cook a small portion in the cavity loosely (about 2 cups), and the bulk in a separate casserole.

Why sourdough beats other breads

• White sandwich bread — too soft, becomes mushy
• Cornbread — flavorful but falls apart
• Sourdough — structured, flavorful, holds shape, crisps beautifully

Day-old sourdough has the perfect texture. Fresh is too soft, too-stale is too dry to absorb broth properly.

Bread quantity

Plan ¾ cup of dried cubes per person. For 10 people, that's about 8 cups. Most home cooks make more for leftovers — 1 cup per person is a generous portion.

The wet-to-dry ratio

For 1 kg of dried bread cubes, you want about 750ml of liquid (broth + eggs combined). Adjust for your bread.

If your bread isn't fully dried, use less liquid. If your bread is rock-hard, use more.

Make-ahead

Stuffing can be assembled (without baking) up to 24 hours ahead and refrigerated. Bake straight from cold — add 15 minutes to the bake time.

You can also bake fully a day ahead and reheat in a 350°F oven for 25 minutes covered, then 5 minutes uncovered to re-crisp.

Variations

• Sausage and apple — add 2 chopped apples sautéed with the onion
• Mushroom and herb — add 1 lb mushrooms cooked with the celery
• Cranberry walnut — add ½ cup dried cranberries and ½ cup chopped walnuts
• Oyster — add 1 pint shucked oysters to the broth (a Northeast tradition)

Common mistakes

Mushy stuffing — too much liquid, or bread wasn't dried enough.

Dry stuffing — not enough liquid, or over-baked.

Bland stuffing — under-salted, or weak broth. Use the best broth you can find or make.

Hard, tough top — over-baked uncovered.

Storage

Refrigerate leftovers up to 4 days. Reheat individual servings in the microwave or oven.

Stuffing freezes well for 2 months. Reheat from frozen at 350°F covered, then uncover for the last 5 minutes.

A pre-Thanksgiving practice

Don't make this for the first time on Thanksgiving Day. Make it for a casual Sunday dinner first. You'll work out timing, salt levels, and bread quantity without the holiday pressure.

Beyond Thanksgiving

This recipe is too good to make once a year. Try it as:

• A side for roast chicken (regular Sunday)
• The base of a strata for brunch
• A bed for poached eggs
• A casserole all to itself for a weeknight dinner

Sourdough stuffing earns its place in regular rotation, not just on holidays.
