Ingredients for Pizza Stuffed Mushrooms

  • Mushrooms: I suggest you use either cremini mushrooms or Baby Bella mushrooms for this recipe. They cook well and are so easy to stuff!
  • Cream Cheese: You really should use the full-fat cream cheese as opposed to reduced fat or fat free. The full-fat cream cheese holds it’s shape better and doesn’t melt out of the mushroom. Also, be sure you do not use a tub of whipped cream cheese. That is a totally different texture and isn’t made for cooking.
  • Grated Cheese: This one is really up to you since some people are particular about the kind of cheese they prefer. I used Mozzarella for my recipe since it seemed the most traditional pizza cheese. You could also use grated Parmesan or cheddar if that’s what you have on-hand.
  • Seasonings: Make it easy on yourself and just use an Italian Seasoning Blend! You can add a little extra garlic powder if you want or even a hint of red pepper flakes. I just stuck with the Italian Seasoning Blend for the easiest stuffed mushroom recipe ever!
  • Pepperoni: I used regular pepperoni but you could use turkey pepperoni if you prefer.
  • Onion: I used a yellow cooking onion, but you could also use green onion if you prefer a milder onion flavor. Just be sure to dice them nice and fine. I actually think I left mine too large for the small size of the mushrooms.
  • Optional Ingredients: You could also add chopped black olives, green pepper, artichoke hearts or any of your other favorite pizza toppings!

How to Make Pizza Stuffed Mushroom Recipe

Start by preheating your oven to 375 degrees. I used a 10″ cast iron skillet, but you could use a baking sheet or any other oven proof dish. Lightly grease your pan either by using a cooking spray or spreading a thin layer of olive oil on the pan. I just took a pastry brush and smeared some olive oil across the bottom of my skillet.

Then wash mushrooms well using a damp cloth. Pop the stems out and save for later. (I actually chopped my mushroom stems up and put them in a baggie for an omelet the next morning.)

In a small bowl, add the cream cheese, grated cheese and Italian seasoning. Stir together well until it’s completely combined. Then fold in the chopped onions.

Use a small spoon to fill each mushroom cap with the cream cheese mixture. Fill your skillet with the stuffed mushrooms and bake for about 15 minutes.

Then turn your oven to broil and broil for a couple minutes until the tops are nice and browned but not burnt. Keep an eye on them since they can burn fast on the broil setting!

Carefully remove from skillet and serve while they’re still hot!

Can You Make Stuffed Mushrooms Ahead of Time

My favorite recipes are the ones that can be prepped ahead of time and stuffed mushrooms are no exception!

You can mix up your filling and stuff your mushrooms with it then store them in the fridge for a day or so until you’re ready to bake them.

You can also freeze your stuffed mushrooms so you have something ready for unexpected guests! I prefer to freeze them uncooked but they can also be frozen already cooked and then just reheated.

To freeze them uncooked, line your stuffed mushrooms on a parchment lined baking sheet and place it in the freezer. Let them flash freeze for about an hour and then transfer them to a freezer bag.

On the day you want to make them, you can let them thaw and follow the cooking instructions above. Or you can cook them from frozen at 325 degrees for about 30 minutes. JustĀ  keep an eye on them and make sure they’re hot all the way through!
