Holiday Stuffed Portobello Mushroom Recipe

Happy Mushroom Monday!

This is such a fun mushroom recipe because it includes a few surprising Holiday ingredients that compliment each other perfectly! Cranberries, walnuts, mushrooms...these are a few of my favorite things. ;) When you combine them together, it's a beautiful medley of flavor!

I had a great response to my Pesto Stuffed Mushroom recipe a little while back so I wanted to create one with a Holiday twist. For this week's mushroom recipe, I combined the heartiness of lentils and walnuts to create a satisfying yet healthy stuffing with the sweetness of dried cranberries. The use of portobellos adds a 'meatiness' to this dish. I love this recipe as a meal or an appetizer!

When cooked, portobello mushrooms have a steak like flavor and texture without the cholesterol, fat, and high calories beef contains. It's the perfect addition to this healthy and satisfying dinner! Mushrooms are full of essential nutrients to boost your energy and are great sources of potassium, riboflavin, niacin and selenium. Portobello mushrooms in particular is a great source of potassium which is great for the heart.

These stuffed portobellos are great as an appetizer (you can even substitute the smaller baby bellas for the bigger portobello mushrooms I use in this recipe) or as a full meal alongside mashed potatoes and gravy or the traditional Holiday sides. Satisfy everyone by serving these at your next Holiday party!

Let's get started!
