These Stuffed Portobello Mushrooms Alfredo with chicken are a low-carb, gluten-free twist on everyone's favourite pasta dish!
How to make this recipe
- In a small oven-safe dish, coat chicken in olive oil and season with salt and pepper. Bake the chicken until it is cooked through.
- While the chicken is cooking prepare the veggies. Wash mushrooms and scoop out mushroom pulp, then mix with other veggies in a large bowl and fill mushroom caps back up with veggies. Place in oven on a parchment-lined baking sheet and cook.
- Meanwhile, in a small sauce, melt butter over med-high heat. Add garlic and saute until fragrant. Once you've sauted the garlic then you will add flour, stirring frequently to remove lumps. Add cream and milk, whisking to prevent any lumps. Finally, add cheese stirring well and cooking until sauce has thickened.
- At this time, take the chicken and mushrooms out of the oven. Pour alfredo sauce over veggie mixture in mushrooms, then top with chicken. Serve and enjoy!

How do you make portobello mushrooms not soggy?
Mushrooms have a high water content. This means that when they're being cooked, they release a lot of water, which can cause them to be soggy. To avoid soggy stuffed portobello mushrooms, you will want to make sure not to rinse the mushrooms under the sink. Instead, wipe down the mushrooms with a damp cloth.
When you're ready to cook your mushrooms, the best thing you can do is partially cook the mushrooms, cap-side facing up, prior to stuffing them. This will allow some of the liquid to escape prior to cooking with the stuffing!
Storing and reheating
To store your leftover stuffed mushrooms, you will want to put them in an airtight container. Your leftovers will only last one day in the refrigerator so you will want to make sure to eat them the next day. To extend the life of this dish a little longer, you can store the stuffing and the mushroom caps separately and prepare them when you're ready to serve them. This technique will let your dish last in the fridge for up to three days.
When you're ready to enjoy your stuffed mushrooms, heat them in a microwave-safe container for one minute or on a pan in the oven for 5-10 minutes at 325 degrees.
