Anytime it comes up in conversation I’m just like whaaaaat? How is it the holidays already?!

If you’re in the same boat as me, I feel ya. And that’s why I’m bringing you Thanksgiving recipes these past couple weeks. So that you have one less thing to think about. Last week I shared my Slow Cooker Pumpkin Bread Pudding, and in the theme of slow cookery, today’s stuffing recipe is a Crockpot gem too.Ahhhh stuffing. Are you noticing a theme here? Dessert made with bread. Side made with bread. Yes, I love bread. When I was younger, I never really liked stuffing. Probably because I was hardcore vegetarian back then and even something made with chicken broth was off limits. It wasn’t until people started making vegetarian versions of stuffing for me and I started pouring my veg gravy over it that it really clicked. Now I luuuurve stuffing. Esp when paired with gravy. Today’s version is made with mushrooms because they provide that meaty, savory umami bomb that you want out of a stuffing. And it’s got walnuts because I like a little crunchy crunch in my stuffing. It breaks up the bready (technical term) texture. And it lends a little nuttiness to the flavor too.

This stuffing is made in the slow cooker because you know that oven is going to be PACKED come Thanksgiving. It’s nice to not have to worry about oven space for every single dish that’s being made. Plus, the slow cooker cooks stuffing really well. The bread pieces on the bottom get really crispy like they would in the oven. We had this stuffing last night with pork chops and Brussels sprouts and it was such a nice hearty cold-weather meal. It totally hit the spot. Steve loved the stuffing and I know you all (and your guests!) will too.

A delicious, savory, umami-filled side dish, this slow cooker mushroom stuffing will not take up any oven space on Thanksgiving!


  • 1 16-ounce stale loaf of white or sourdough bread, cut into 1-inch cubes
  • 4 tablespoons butter
  • 1 extra-large or 2 medium onions, diced
  • 4 large celery stalks, diced
  • 4 cloves garlic, minced
  • 1 lb cremini (or baby bella) mushrooms, chopped
  • 1/4 cup chopped fresh sage leaves
  • 2 tablespoons chopped fresh rosemary
  • 1 tablespoon fresh thyme leaves
  • 2 eggs
  • 3 cups chicken broth (or vegetable broth)
  • 1 teaspoon salt
  • Freshly ground black pepper
  • 3/4 cup chopped walnuts


  1. In a large saute pan, melt butter over medium-high heat. Add the onions, celery and garlic and cook until tender, about 5-7 minutes.
  2. Add mushrooms, sage, rosemary and thyme and cook until mushrooms are tender, about 5 minutes.
  3. In a medium bowl, whisk together eggs, chicken broth, salt and pepper.
  4. In a greased slow cooker, add bread and fold in sautéed vegetables and walnuts.
  5. Pour broth mixture over bread and gently toss to evenly coat the bread.
  6. Cover and cook on low for 3-4 hours.


  1. You can substitute vegetable broth for chicken if you want to make this stuffing vegetarian.

Tell me, have you ever made stuffing in the slow cooker before?

    If my stuffing is still wet does it need to cook longer? How do I know when its done?

    • Hi May! You want your stuffing to be moist but not wet (there shouldn’t be any liquid remaining). If it’s wet, you can cook it longer. Cook until the stuffing is heated through. Be careful not to overcook – watch for the edges of the bread getting dried out.

    What kind of mushrooms

    Great idea to use the crockpot to free up oven space. I was going to make it ahead, but will now wait till Christmas Day, and have it cooking merrily away in the corner!

    • The crockpot really is a life saver for those big holiday dinners. If you did end up making it for Christmas, I hope it was delicious!

    When do you add the sauted mixture? Should I add the bread to the saute pan and then transfer it all to the greased slow cooker? Or add the veggies after the bread is in the slow cooker?

    • Hey Heather – great question! You can add the veggies after the bread is in the slow cooker and fold them in with the walnuts. I’ll update the instructions now!

  5. I never knew you could make stuffing in a slow cooker! This is a great way to free up counter space too 🙂
