Video of the Day
Step 1: Toast Breadcrumbs
Preheat oven to 250 degrees F. Place breadcrumbs in a single layer on a large baking sheet. Bake for about 25 minutes. Remove from oven and allow to cool.

Step 2: Sauté Onions and Celery
While the bread is cooking and cooling, sauté onions and celery in 3/4 cup of melted butter, about 10 minutes, until the vegetables are soft.

Step 3: Combine Eggs with Chicken Stock
In a small bowl, whisk together eggs and chicken stock.

Step 4: Mix to Combine
In a large mixing bowl, combine the breadcrumbs, herbs, and onion mixture.

Add the egg and chicken stock mixture, then stir until everything is combined.

Step 5: Bake
Prepare a 9x13-inch casserole dish with a thick coat of butter. Then pour in your stuffing mixture. Cover with foil. Bake the assembled stuffing dish at 350 degrees F for 30 minutes. Remove the foil and bake for another 15 minutes until the edges are golden.

Tip
-
If cooking ahead of time, allow to cool completely. Replace foil over the top and store in the refrigerator. Reheat at 250 degrees F, covered, for about 35 minutes. Add 1/4 cup extra stock if the stuffing starts to dry out.
