Chef Jenn’s Tips

  • Steak-Umms and other cheesesteak beef can have a fair bit of water content added to it. Be sure to drain this water from the pan before you add the cream cheese.
  • Chop your onion and bell pepper pretty small so it all fits into the mushroom cap.
  • You can change up the mushrooms – try this recipe with cremini mushrooms or jumbo portobellos
  • Add a bit of red pepper flakes if you like it spicy!

When To Serve These keto Stuffed Mushrooms

These Philly Cheesesteak Stuffed Mushroom Caps are the perfect game-day snack, but they’re also terrific anytime you need something to munch on.

From potlucks to gatherings of all kinds, put out a tray of these bite-sized morsels of goodness and watch them disappear!

Are Stuffed Mushrooms Freezer Friendly?

Yes! Of course they’ll never be quite as good as they are fresh, but these keto appetizers will freeze just fine.

Freeze them on a sheet pan until frozen, then pop them into a freezer-safe plastic zipper top bag.

They’ll stay fine for about three months in the freezer.

Thaw them in the fridge until thawed, then heat them in the oven or the microwave until warmed through.

Are mushrooms good on a keto diet?

Yes! Double yes! Mushrooms are perfect for a keto diet. Not only are they loaded with plenty of nutrients, they are low in carbs and have a bit of fiber, too.

How many carbs are in stuffed mushrooms?

Of course it varies by recipe, but in this recipe you’ll find about XX net carbs per serving. The serving size depends on how big your mushrooms are.

How do you clean mushrooms?

I wash the mushrooms to remove all the growing medium that’s left behind. You can also just use a soft brush to brush them off, but water won’t hurt them.
