I whipped up this Mushroom Casserole a couple years ago as a Thanksgiving side, & it was a cheesy instant hit! What could be better than cheese, mushrooms, & breadcrumbs? Get my mushroom casserole recipe below.


Ingredients 

  • 8 cups chopped mushrooms - I used trumpet, cremini, cordyceps 

  • 1/2 stick butter

  • 7 cloves garlic

  • 1/2 chopped onion (or 2-3 shallots)

  • 1 tsp celery powder

  • 1 tbsp onion powder 

  • 1 tbsp garlic powder

  • 1 tbsp Himalayan sea salt

  • 1 tbsp cracked black pepper

  • 4-5 sprigs fresh chopped sage

  • fresh minced chives

  • 4 tbsp butter

  • 2 tbsp corn flour

  • 1 pint heavy cream

  • 4 cups shredded sharp cheddar (or Gruyere)

Topping:

  • 3/4 cup gluten free baguette, croutons, or stuffing

  • 2 tbsp butter


The Process

  • sauté mushrooms, onions, & garlic with 1/2 stick butter in a deep sauté pan

  • add in the following seasonings: celery salt, onion powder, garlic powder, Himalayan sea salt, cracked black pepper, fresh sage

  • once veggies are fully cooked, remove them from the deep sauté pan & place off to the side in a bowl

  • once the veggies are off to the side, use the same deep sauté pan to make a roux with the 4 tbsp butter & 2 tbsp corn flour

  • stir heavy cream into the roux, & slowly add in the shredded cheese

  • once cheese is fully melted, stir veggies back in

  • pour your cheesy mushroom mixture into a ceramic or glass pan to bake

  • before baking your casserole, heat up your crunchy topping in a small pan with the GF baguette & 2 tbsp butter

  • bake at 350 degrees Fahrenheit for 20 minutes

  • top with fresh chives after cooking


Enjoy & Happy Holidays!
