Ingredients you will need:
(For the full recipe, scroll down to the recipe card below)
- Mushrooms : Look for large white button mushrooms or cremini mushrooms.
- Spinach : opt for the fresh spinach
- Wild Rice Blend : Wild Rice is a 100% whole grain and is a good source of complex carbohydrates and protein. I love the nutty flavor and chewy texture it adds to these stuffed mushrooms!
- Panko Breadcrumbs : or you can use Italian breadcrumbs
- Shallot : sautéing the shallot with celery adds great flavor
- Celery : be sure to chop it nice and small
- Parmesan cheese: freshly grated, not the pre-packaged stuff!
- Mozzarella cheese: freshly shredded, it will melt better. The milk and melty mozzarella paired with the salt Parmesan work wonders together!
- Egg : helps to bind the filling
Step by Step Directions
(For the full recipe, scroll down to the recipe card below)
- Roast the mushrooms first : Roasting the mushrooms before you fill them up helps to release their water. Remove the stems and reserve the stems in a bowl. (We will add these to the filling!) Place mushrooms on a baking sheet and bake at 400°F for 10-13 minutes. You’ll notice the centers of the mushrooms fill up with water. Carefully discard the water.
- Make the filling : sauté the celery and shallot for ~3 min. Add in the finely chopped mushroom stems, garlic and seasoning and cook for another minute.
- Then add in the spinach and cook until it wilts down.
- Place this into a medium-large bowl. Add in both cheeses, cooked rice, breadcrumbs and eggs. Stir until combined.
- Fill the mushrooms with the wild rice filling. Be generous with the filling.
- Bake for 13-15 minutes , or until mushrooms are tender and the filling is hot.
I love incorporating a wild rice blend into these vegetarian stuffed mushrooms not only for the phenomenal flavor and texture it adds, but because US-Grown wild rice is nutrient rich. It contributes more than 15 vitamins and minerals, including folic acid and other B-vitamins, as well as iron and zinc.
Expert Tips and tricks
- Choose the right mushroom . I find the large white button mushrooms are easiest to work with and are ideal for stuffing. You don’t want them too small because you won’t have a good stuffing-to-mushroom ratio.
- Clean the mushrooms : Take a few extra minutes to ensure all dirt is removed (place in a colander and rinse thoroughly with cold water) and wipe clean with a paper towel.
- Reserve the mushroom stems : Finely chop the stems and use them in the filling. Carefully pop them out, being sure not to break or crack the mushroom cap.
- Roast the mushrooms to release excess water: no one likes a soggy stuffed mushroom! Mushrooms retain a lot of water, and roasting them before helps to release some of the excess liquid that we don’t need baked into the final dish.
- Make them in advance: stuff the mushroom caps in advance (up to 1 day ahead) and refrigerate. Bake as directed.
