mushrooms au gratin

I adore mushrooms.  Doesn’t matter to me how they’re prepared, what type of mushroom it is, or if it’s appetizer, entree, or dessert (okay, even I draw the line at dessert…maybe).  Add a sour cream mixture and add a layer of cheese?  I’m in food heaven. 

The trick to getting the most flavor from your mushrooms is to cook them over HIGH heat.  You almost want to think of your meaty mushrooms as a nice, juicy steak…put them in a very hot pan, and don’t touch them for at least a few minutes, and preferably after they’ve released all their moisture and it’s evaporated.  You want to get a nice, golden color to them before flipping them – that’s how you’ll build the most flavor.

This is a great mushroom recipe that even my kids will eat (well, one of them).  The leftovers heat up very nicely and taste just as good as when they’re fresh out of the oven.  I hope you enjoy them!

mushrooms au gratin

  • 4 tablespoons butter
  • 2 lbs fresh mushrooms, sliced thick (I use cremini)
  • 2/3 cup sour cream  
  • 1 – 2 tablespoons flour
  • 1/4 cup chopped fresh parsley
  • 1 cup shredded cheese (swiss works great here, although I usually use a mexican blend that works fine)

Preheat your oven to 400 degrees.

Put mushrooms in a very hot pan, cooking until they’re good and browned. 

Mix together the sour cream and flour.  Add a little salt and pepper, too.

Add to the mushrooms in the pan.  Cook it for about a minute or so.

Transfer the mixture to a greased baking pan (I use an 11×7).  Top with cheese and parsley.

Bake for about 10 – 15 minutes, then enjoy!

Hi guys,

I know this might be a bit off topic but seeing that a bunch of you own websites, where would the best place be to host. Someone recommended I use Blue Host for $6.95 a month which seems like a great deal. Anyone here on using them?

Mushrooms tend to soak up any moisture in a pan pretty quickly, so your butter shouldn't burn. I've never had any problems, but you if you're concerned you can always add a bit of olive oil to the butter and that will give you a higher smoke point.

Do we saute the mushrooms in butter, or just throw them in the pan? Won't the butter burn at that temperature?
