Simple Ingredients
Mushrooms: Look for large portobellos that are intact with deep caps. To make bite sized appetizers, use buttons or creminis (baby bellas).
Meat: Chicken adds a hearty and savory flavor to this stuffed portobello mushroom recipe for a satisfying low-carb meal. Lean chicken is light, but still provides plenty of rich taste. Be sure to drain any excess fat after cooking to keep the filling from becoming too greasy.
Filling: Seasoned cream cheese and sundried tomatoes make the perfect filling for stuffed portobellos. Make your own Italian seasoning and have some leftovers for other savory dishes.
Cheese: Mozzarella adds a creamy, gooey texture, while parmesan brings a bold, slightly salty flavor. For an extra cheesy finish, sprinkle a little more on top before serving.
