I love finding new ways to enjoy vegetables. Oftentimes, it’s also a new way to enjoy cheese!

These low carb stuffed mushrooms are a great example. Tender baked mushrooms are filled with a creamy mixture of onions, garlic, cream cheese, and mozzarella, then baked to rich and melty perfection.

Cheese? Check. Vegetables? Check. Easy to throw together in about 10 minutes? Check!

So the next time you’re looking for an appetizer that will please a crowd, these low carb and meatless stuffed mushrooms are a great option. Who can resist all that melty goodness?

How to make low carb stuffed mushrooms

This recipe only takes about 10 minutes to prep and 20 minutes to bake, so you can be ready to serve in about half an hour!

Ingredients for recipe separated into different ramekins, as seen from above

Step 1: Preheat your oven to 350 F (180 C).

Step 2: Remove the thick stems from the mushrooms, then chop the stems roughly.

Step 3: Place the mushrooms caps into a baking dish.

Step 4: Heat a large frying pan over high heat. Add the olive oil. Once the oil is hot, add the onions.

Step 5: Once the onions are translucent (about 5 minutes), add the chopped mushroom stems and cook for another 3 minutes.

Step 6: Add the garlic and cook until fragrant, about 1 minute.

Step 9: Place the mushrooms in the oven and bake for 20 minutes or until the cheese is melted and golden.

I recommend giving the mushrooms a few minutes to cool. They’re so tempting fresh out of the oven, but the cheese mixture is very hot, and you don’t want to burn your mouth!

Finally, garnish with fresh chives before serving.

What kind of mushrooms are best for this recipe?

I like to use larger brown mushrooms for this recipe. Six of them definitely fill my baking dish!

So when you’re at the grocery store, look for any good-sized brown mushrooms. You don’t want them to be bite-sized, but you don’t want the biggest portobello mushrooms either. Something right in the middle is perfect!

Storage

These mushrooms are best enjoyed immediately. That way, the cheese mixture will be hot and bubbly and the mushrooms will be tender!

If you do have leftovers, you can store them covered in the refrigerator. I recommend eating within 3-4 days.
