Ingredients for keto friendly Stuffed Mushrooms

How to Make Perfect Keto Friendly Stuffed Mushrooms

Step One: Preheat your oven to 350F. Spray your baking sheet lightly with oil, or line it with parchment paper or a silicone mat. 

Step Two: Allow cream cheese to soften. Softened cream cheese will be easier to mix with the other ingredients to make a soft, creamy filling. I typically take cream cheese out of the fridge and let it sit at room temperature for about half an hour before starting the meal prep. 

Step Three: Combine ingredients for filling and mix until the cheese mixture is smooth. Set aside.

Step Four: Bake mushrooms before stuffing them. First, remove their stalks, then place them bottom-side up on your prepared tray. Pop them in the oven for about 3-4 minutes, or until slightly softened.

Step Five: Flip and fill the mushrooms with the cream cheese mixture. Continue baking for about 4 more minutes. Keep in mind that mushrooms cook quickly, so smaller mushrooms are likely to be done in under 8 minutes. Adjust your baking time accordingly, baking until the mushrooms are fork-tender and the cheese filling is bubbling. 

Step Six: Sprinkle with chives and serve warm as an appetizer. These keto stuffed mushrooms can be enjoyed on their own or with sides including my Roasted Root Vegetables or this simple Tomato Salad.

Frequently asked Questions about Low Carb Stuffed Mushrooms

Can I make stuffed mushrooms ahead of time?

Yes! My keto stuffed mushrooms are the perfect appetizer to prepare ahead of time. You won’t need to bake them twice, but since they’ll be coming from the fridge, you’ll need to bake them slightly longer than 8 minutes until warmed through.

Simply pre-fill the mushrooms and store them covered in the fridge until you’re ready to bake them. Stuffed mushrooms that have been prepared in advance should be baked within 2 days.

Should I wash mushrooms before stuffing them?

It’s always a good idea to wash mushrooms before cooking in order to remove dirt. However, you should avoid soaking the mushrooms in water as you clean them, otherwise they could turn out soggy when baked.

Some mushrooms you’ll find at the store may already be pre-washed. If the package doesn’t indicate that they’ve been washed, place the mushrooms in a colander and give them a good rinse. If any dirt remains, you can use a paper towel to lightly rub it away.

How long can baked stuffed mushrooms last in the fridge?

After being baked, keto stuffed mushrooms will keep in the fridge for up to 5 days. Allow them to cool fully before transferring them to a storage container. For best results, store stuffed mushrooms in a single layer in an airtight container, or in layers separated by parchment paper.

Leftover stuffed mushrooms can be reheated in the oven, or in the microwave if you want to heat them up quicker.

This is a great appetizer idea for the holidays. Your guest will love these Keto Stuffed Mushrooms as they provide a ton of flavor thanks to the combination of blue cheese and chives.

  • Filling variations are endless, my favorites are caramelized onion with parmesan cheese, and sundried tomatoes, cream cheese season with Italian herbs!
