Make this recipe with Ranch or Italian Seasoning

My neice had posted a recipe on Face Book and my daughter wanted to make the mushroom recipe. I looked at the recipe and told her, that’s not the recipe for the crockpot mushrooms.

Time Tested Mushroom Recipe

I had been making savory slow cooker mushrooms for well over 20 years and I quickly rattled off the recipe that I made. Well, she tried the recipe from Face Book and it was not very good. WAY too much butter and seasoning for the amount of mushrooms.

We had a mushroom cook-off

My daughter wasn’t giving up on the new mushroom recipe.

She still wanted to try making the recipe. I told her my recipe and she used a packet of ranch dressing mix powder instead of the italian dressing seasoning I use. Here are some photos of the results.

Ranch Mushrooms

This batch tasted wonderful. If you like ranch flavoring, this recipe would tickle your taste buds.

Mushroom Serving Suggestions

Serving a large crowd

Leave the mushrooms right in the slow cooker to stay warm. Let the guests serve themselves as an appetizer or side dish.

Serving with a meal

Serve the buttery and savory sauce with the mushrooms over a steak or chicken. What a great sauce to compliment the meat.

I have also used the savory mushrooms added to pasta with cut up chicken, pork, or steak cut up. Very tasty all by itself.

Savory Slow Cooker Mushrooms

I got this recipe at a potluck many years ago. Someone brought a slow cooker half full of these tasty mushrooms. They were gone and everyone was asking for the recipe.

  • Turn the crockpot on low. Add the butter and either the italian or ranch seasoning packet. Add the mushrooms – they can be sliced or kept whole.
  • Cook for 3-4 hours on low. Serve and enjoy. Note: the mushrooms will shrink and be about 1/3 of their original size when they are cooked. So if you want a lot, use a very large crockpot and double or triple the recipe.
