How to Make Perfect Low-Carb Stuffed Mushrooms

Preheat Your Oven – Preheat your oven to 350°F. Prepare a baking sheet by lightly spraying it with oil or lining it with parchment paper or a silicone mat.
Prepare Cream Cheese – Let the cream cheese sit at room temperature for about 30 minutes to soften, making it easier to mix.
Make the Filling – In a bowl, combine the softened cream cheese with the other filling ingredients. Mix until smooth and set aside for later use.
Prepare the Mushrooms – Remove the stems from the mushrooms and arrange them bottom-side up on the prepared baking sheet. Bake for 3-4 minutes to soften slightly.

Stuff the Mushrooms – Flip the mushrooms over and fill each one with the prepared cream cheese mixture.
Bake – Return the stuffed mushrooms to the oven and bake for another 4 minutes, or until the mushrooms are fork-tender and the cheese starts to bubble.
Garnish and Serve – Sprinkle with chives just before serving. These stuffed mushrooms are great on their own or paired with side dishes like roasted root vegetables or a fresh tomato salad.
