Ingredients For Crockpot Mushrooms
Here are the ingredients you will need to make this crockpot ranch mushrooms recipe:
- Butter: salted or unsalted butter work great; use your preference.
- Dry Ranch Dressing: store brand or name brand seasoning both works.
- Onion: use any variety. White, yellow, or Vidalia work great in this recipe.

Meal idea! One of my favorite meals that I make these mushrooms for is to top off a really delicious steak. Choose your favorite cut of steak and cook until your desired doneness. Scoop the mushrooms over the top of your steak and pair it with a baked potato and a small side salad to start out your meal. Steakhouse at home!
Variations
Here are some suggestions for customizing your buttery slow cooker ranch mushrooms:
- Omit the onion and/or the bell pepper if desired.
- Add a cajun seasoning mix, chipotle seasoning, or crushed red pepper flakes for a bit of heat.
- Add a quarter cup of white or red wine to your mushrooms while they are cooking for extra flavor and depth.
- Feel free to add some fresh minced garlic or other seasonings and herbs that you love.
Slow Cooker Tips
Tip #1: Add a cornstarch slurry to your mushrooms to thicken the liquid to a sauce texture that helps coat the mushrooms for more flavor! Use a 1:1 ratio of water to cornstarch and mix together before adding to the crockpot. Add more slurry until your desired thickness is achieved.
Tip #2: For more tender onions, give them a head start by microwaving them for 5 minutes on high before placing them in the slow cooker.
Tip #3: Remove the stems on the mushrooms if preferred. Some people prefer to eat the "button" part only on mushrooms. I personally like them, so I leave them on for our family.
