Ingredients You Need: 

  • Cremini Mushrooms – this will be the mushroom base! You can also use white button mushrooms. 
  • Mild Italian Sausage – used for the filling inside the mushrooms 
  • White Cheddar Cheese – this packs a nice punch of flavor and melts so well!
  • Parmesan Cheese – used for the breadcrumb topping – a must! 
  • Panko Breadcrumbs – these are extra crunchy and a must have for texture! 
  • Red onion – used for flavor in the mushroom stuffing! 
  • Fresh garlic – used for both the mushroom stuffing and the garlic butter! 
  • Salted butter – you can use unsalted if needed. 
  • Salt and pepper to taste – for flavor! 
  • Fresh thyme – you can use dried if you need to, but I love fresh for this recipe. 

How to Make Stuffed Mushrooms in a Few Simple Steps: 

  1. Preheat the oven to 400 degrees. Clean the mushrooms and gently but firmly pop out the stems. Place the stems on a cutting board. While you’re there, mince them finely as well as 5 cloves of garlic. Dice red onion into bite size pieces. Set all of this aside for now. 
  2. Heat a large skillet on medium high heat. Add the mild Italian sausage and cook for 7-10 minutes, breaking up into SMALL pieces until it’s done. Stir this continually. Once done, add to a large glass bowl. 
  3. To the same pan that you cooked the sausage in, add the red onion. Cook for 2-3 minutes and add a pinch of salt. Add the chopped mushroom stems, and stir around. Cook for another 2-3 minutes. Add in half of the chopped garlic and cook for 1 more minute. Remove from the pan and place in the bowl with the cooked sausage. 
  4. Shred both of the cheeses. Add the white cheddar cheese to the bowl with the cooked sausage. Set the parmesan cheese aside for now. 
  5. Line a large baking sheet with parchment paper and add the mushrooms with the hole facing up. Melt butter in a small bowl and add in the rest of the chopped garlic along with chopped thyme. Stir and then use a kitchen brush to brush it on each mushroom. In the same bowl, add the panko breadcrumbs and shredded parmesan cheese. Mix to combine.3 side by side photos - one of the mushroom brushed with garlic butter, the next topped with the breadcrumb mixture and the 3rd freshly baked and out of the oven!
  6. Stuff each mushroom generously with the sausage mushroom onion filling and then top with the panko parmesan topping. Bake for 12-14 minutes or until golden brown. Serve immediately! Top with more parmesan and fresh thyme if desired. 

Best Tips for Success: 

Make sure that the mushrooms are mostly the same size if possible! This will make sure they cook more evenly – not to mention, they will look nicer when presented as an appetizer at your holiday party! 

Try to slice and dice your veggies all at the same time – that way you can focus on other things as you cook this recipe.

Taste and adjust seasoning to your mushroom filling if needed. You want to make sure that it tastes perfectly delicious before it’s baked into the mushrooms!

Work smart and re-use bowls if possible! For example, use the bowl that you made the garlic butter mixture in when you need to mix the panko/parmesan mixture. This will make sure you won’t have to do as many dishes! Win win. 

Ingredient Variations: 

If you like your appetizers a little more spicy, use Spicy Italian Sausage and pepper jack cheese! 

If you like your appetizers a little more mild, use sweet Italian sausage and use a milder cheese like gouda.

If you can’t find cremini mushrooms, feel free to use white button mushrooms.

Use a shallot or yellow onion in place of red onion if needed. 

Use unsalted instead of salted butter if desired.

Storing Leftovers: 

These are best eaten the day of while warm – however, if you do have extra leftovers, store in a tightly sealed container in the fridge for up to 2 days. Reheat when ready to eat.
