What goes into the Easy Crockpot Sage and Onion Stuffing?

To make this easy and delicious old fashioned sage and onion stuffing in the crockpot, you will need:

  • Sourdough bread. You could opt for stuffing cubes if you like, but either use untoasted and toast them yourself according to the recipe, or use additional chicken stock to moisten them. I prefer to toast my own bread, and cut it myself, as it adds a better texture to the final product.
  • Lots of butter. The butter will be used to grease the crockpot, as well as to sauté the celery and onion, and top the stuffing prior to cooking.
  • Celery, onion and garlic. No stuffing recipe is complete without these! I like to chop mine super tiny.
  • A bunch of chopped fresh sage leaves. You’ll use about 1 whole 0.66 oz package, aka the little herb cases at the supermarket.
  • Poultry seasoning– use your favorite!
  • Store bought or homemade chicken or turkey stock. Use whatever you like, just make sure it is high quality for best flavor.
  • Beaten eggs. These are crucial for keeping the stuffing moist.

Prepping the Sage and Onion Stuffing for the Crockpot

Toasting the bread

Before you assemble the stuffing, you will toast the bread in a 400 degree oven for 15-20 minutes, until the bread is dry and crisp. This will help the stuffing texture, and ensure the bread absorbs the liquid.

Prepping the veggies

Finely chop your celery, onions and garlic. You’ll cook the celery and onion in some butter and a bit of salt until softened, then add the garlic and cook until just fragrant. After this, you’ll add it to a LARGE bowl with the eggs, toasted bread, seasoning and chicken stock, and mix well before adding to the greased and preheated crockpot.

How long do I cook the stuffing in the crockpot?

The stuffing takes between 3 and 3.5 hours to cook in the crockpot, once it is prepared. First, you will toast the bread, cook the celery, onion and garlic, and mix well with the wet ingredients. Greasing your crockpot with butter prior to cooking is key to not only get crispy edges, but also to prevent sticking.

Serving the stuffing

Serve this stuffing right out of the crockpot! You can either leave it as is, or give it a good stir to evenly distribute the crispy edges into the stuffing. Keep an eye on the stuffing, and once the edges are crispy, turn the heat on the crockpot to warm until ready to eat.

Storing the leftover stuffing

Once the cooked stuffing is cooled, you can store any leftovers for up to 5 days in the fridge, either in an airtight container, or a ziplock bag.
