Parmesan Bacon Sourdough Mushroom Stuffing

One of the most popular Thanksgiving recipes on Ambitious Kitchen… STUFFING!

Since I already have my favorite cornbread stuffing (it’s gluten free) on the site, a few of years back I decided to make a version with sourdough bread (2020 was the year of sourdough). After experimenting with a few different flavor combos I landed on the most incredible parmesan bacon mushroom stuffing that truly blows any other stuffing recipe out of the water. Trust me!

The sourdough bread soaks up the flavor of parmesan, bacon and caramelized mushrooms perfectly, but of course, if you don’t have sourdough, cornbread would be an excellent replacement. Get all of my tips and tricks for making this best-every mushroom stuffing within the post, and let me know if you try it this holiday season!

What is stuffing?

Let’s take it back to basics. What even is stuffing? It’s basically small cubes of bread mixed with a variety of herbs and other items like celery, mushrooms, dried fruit, meats like sausage, nuts and more. People often make it inside the cavity of turkeys (hence the name: stuffing), but you can easily make it in a pan — which is what I prefer.

Ingredients in the best mushroom stuffing

This incredible homemade mushroom stuffing is filled with savory flavor, fresh herbs and wonderful textures in every bite. Here’s what you’ll need to make it:

• Sourdough bread: I’m not a big fan of mushy stuffings so using sourdough bread is key in this recipe. The sourdough gives the stuffing the perfect texture and gets a little toasty on the top. You can also use cornbread if you prefer.
• Bacon: for a little extra savory goodness we’re adding bacon to this stuffing! This is optional, so feel free to omit to keep the stuffing vegetarian.
• Butter: gotta have a healthy dose of good old butter to make the bread super toasty and delicious. Feel free to sub olive oil if you’d like.
• Garlic: fresh garlic adds a delicious flavor throughout the stuffing.
• Herbs: this homemade mushroom stuffing has hints of herby flavor from fresh thyme leaves & sage.
• Veggies: you’ll add baby bella mushrooms, white onion and celery for a variety of textures. Feel free to use wild mushrooms, shiitake mushrooms, oyster or chanterelle, too! Tons of possibilities.
• Salt & pepper: for the perfect amount of seasoning.
• Eggs: you’ll need two eggs to add moisture to the bread.
• Broth: feel free to use vegetable broth or chicken broth for additional moisture. You can use a bit more (as noted in the recipe) if you like a very moist stuffing.
• Grated parmesan: this savory mushroom stuffing has parmesan cheese baked right inside and on top for wonderful cheesy goodness.
• Pecans: add a little crunch with some chopped pecans! They add the perfect texture. You could also use chopped walnuts, or feel free to omit to keep the stuffing nut free.

What type of bread to use for stuffing

I recommend using a hearty bread like sourdough so that the stuffing holds its shape well and gets nice and toasty on top. I would avoid super soft breads and loaves as they can get too soggy. You’ll also want to make sure you toast your bread in the oven before using it in this recipe!

How to dry sourdough bread for stuffing

To dry out the sourdough bread before assembling & baking your mushroom stuffing you’ll simply cut the sourdough into bread cubes and bake it in the oven for about 1o minutes. Easy!

How to make mushroom stuffing from scratch

Good news: this is truly an easy mushroom stuffing recipe that you can make for Thanksgiving and impress guests. Here’s how to do it:

1. Toast your bread. Cut the sourdough into 1/2 inch cubes and place them on a baking sheet. Spray the tops of the cubes with nonstick cooking spray or drizzle with olive oil. Bake for 10 minutes at 375 degrees F to dry out and toast the bread.
2. Cook your bacon. While the cubes are baking, cook your bacon in a large skillet over medium heat. Once it’s done, blot it with a paper towel to absorb excess grease, then chop it into bite-sized pieces.
3. Cook your mushrooms. Next, cook your mushrooms in the same skillet with butter, garlic, thyme and sage. Saute until mushrooms start to become just slightly golden brown, then add in onion, celery and salt and pepper and cook until the onion softens.
4. Mix the stuffing. Transfer the mixture to a large bowl and add in the toasted sourdough cubes, beaten egg, broth, bacon, parmesan cheese and pecans. Gently toss to combine and get the bread moist.
5. Optional: cook in the turkey. Simply stuff the cavity of the turkey.
6. Bake separately. Add the stuffing into a greased baking dish and dot the top with butter pieces or drizzle with olive oil. Sprinkle with parmesan, cover, and bake. Remove the foil and continue to bake for an additional 20-30 minutes or until bread is golden brown on top.

Make your mushroom stuffing ahead of time

This savory mushroom stuffing can be made a day or two ahead of time, so keep that in mind when prepping for the big Thanksgiving day. Simply make the stuffing as directed but instead of baking it, cover it with foil and place it in the fridge until ready. Once ready to bake, follow the recipe as instructed! It will come out delicious either way.

How to store homemade stuffing

If you have any leftover mushroom stuffing, simply store it in airtight containers in the refrigerator for up to 3-4 days. Simply reheat in the microwave and enjoy!

Can you freeze stuffing?

Yes! To freeze this mushroom stuffing for later, simply let the stuffing cool completely, transfer portions of it to freezer-friendly containers and place it in the freezer for up to 2 months. Reheat the stuffing in the oven until it’s warmed through.

Delicious parmesan bacon mushroom stuffing made with sourdough bread and toasted pecans in every bite. This amazing homemade mushroom stuffing recipe is filled with flavor from fresh herbs and melted cheese that will have you going back for seconds. The perfect twist on a classic Thanksgiving side dish!

Ingredients

• 1 pound sourdough, cut into 1/2 inch cubes
• 10 ounces bacon
• 2 tablespoons butter (or can sub olive oil)
• 3 garlic cloves, minced
• 1 tablespoon fresh thyme leaves
• 2 tablespoons fresh chopped sage
• 16 oz baby bella mushrooms, sliced
• 1 large white onion, chopped
• 3 stalks celery, diced
• ½ teaspoon salt
• Freshly ground black pepper
• 2 eggs, lightly beaten
• 1 cup vegetarian or chicken broth (plus another 1/2 cup if you like a very moist stuffing)
• ½ cup grated parmesan
• ½ cup chopped pecans
• 1 tablespoon butter, diced into small pieces (or olive oil)
• Topping:
• 2 tablespoons parmesan, for topping

Instructions

• Preheat the oven to 375 degrees F. Cut the sourdough into 1/2 inch cubes and place them on a baking sheet. Spray the tops of the cubes with nonstick cooking spray or drizzle with olive oil. Bake for 10 minutes to dry out and toast bread.

• While the cubes are baking, cook your bacon: add bacon to a large skillet or pan and place over medium heat, cook bacon on both sides until crispy and golden brown. If the pan starts to smoke at any point, simply lower the heat. I always cook my bacon on medium low heat. Once bacon is done, blot with a paper towel to absorb excess grease, then chop into bite sized pieces.

• Place a large skillet or pan over medium heat. Add in butter. Once butter melts, add in garlic, thyme, sage and mushrooms. Saute until mushrooms cook down and start to become just slightly golden brown. Next add in onion, celery and salt and pepper. Cook for another 3-5 minutes until the onion has softened.

• Transfer mixture to a large bowl and add in the toasted sourdough cubes, beaten egg, vegetarian or chicken broth, chopped bacon, parmesan cheese and pecans. Gently toss to combine and get the bread moist.

• If you want to make it in the turkey: Stuff the cavity of the turkey.

• Otherwise to bake separately: add the stuffing into a greased 12×8 inch or 2 quart baking dish and dot the top with butter pieces or drizzle with a bit of olive oil. Sprinkle with parmesan. Cover with foil and bake at 375 degrees F for 30 minutes. Remove foil and continue to bake for an additional 20-30 minutes or until bread is golden brown on top. Enjoy! Serves 8-10.
