Slow cooker garlic parmesan mushrooms are the ultimate crockpot side dish. This easy and flavorful recipe will instantly elevate any meal you choose to add it to!
This easy dish is for all the mushroom lovers out there. It is made with simple ingredients that produce great flavor. Slow cooking releases the rich, woody intensity that mushrooms are famous for.
While this crockpot recipe is easy enough to serve anytime, I especially love it during the holidays. Even though it requires only a few minutes of prep time, it comes off as unique and special. A perfectly delicious side dish the whole family will love!
📝Shopping List
To make these amazing slow cooker garlic ranch mushrooms, you will need:
- Mushrooms - Baby Bellas and white button mushrooms both work well (the pictures below are of a combination of the two)
- Onion - Diced
- Dill - fresh herbs really make a difference in this recipe
- Parmesan cheese - use fresh gratedcheese, when possible
- Olive Oil
- Ranch Seasoning - You can use the packaged kind or homemade.
🥣How To
Start by cutting off the end of each mushroom's stem. Next, remove the dirt. There is a lot of difference of opinion as to the best way to do this. I do not soak mushrooms in water. A damp paper towel or mushroom brush is an easy way to remove dirt.
Add remaining ingredients to crock pot and stir to combine. Cover your slow cooker, turn on to the low setting, and walk away. Your slow cooker will bring out the rich, earthy flavor of the mushrooms while creating the perfect side dish!
Each slow cooker is a little bit different. In general, these will be ready to eat somewhere in between 3 and 5 hours. My slow cooker mushrooms are usually ready in about 3.5 hours. I have let them sit on warm for several hours after they are finished with delicious results.
🍽Serving suggestions
Slow cooker garlic mushrooms are one of the most versatile side dishes. They can be served alongside turkey, steak, chicken, pork chops, or fish. Green beans and sweet potatoes are also wonderful additions.
This delicious dish will create a lot of liquid while it is cooking. The parmesan cheese and oil will turn it into a flavorful and creamy sauce. To make the most of this amazing sauce, serve over white rice, cauliflower rice, or baked potatoes. It is equally delicious over mashed potatoes or mashed cauliflower.
Storing leftovers
Store crockpot mushrooms in an airtight, sealed container or bag. They will last 3-5 days in the refrigerator and several months in the freezer.
😉Hints & Hacks
- Are you a fan of spice? Dial up the heat in this dish by adding red pepper flakes.
- The best mushrooms for this recipe are baby bellas and white button mushrooms. I often use a mixture of both (as shown in these pictures)
- If you are serving this dish during the holiday season, double the recipe. Your entire family will be asking for seconds. Just make sure your slow cooker is big enough to hold it all.
- To keep things extra lazy, I buy onions that are already diced. They are very inexpensive and can be found in the frozen vegetable section of the larger grocery stores. This saves a ton of time and tears!
- I am a huge fan of slow cooker liners

I made these on 4 Sep 2022, I did cut this recipe in half, and the only deviation from the recipe was I used a little garlic powder in place of the fresh garlic (I just did not want to go to the market), everything else followed exactly! Easy to put together, and the mushrooms are tender, juicy, and the sauce is perfect. I and the family absolutely loved these mushrooms! This will be a regular now. Thank you for the great recipe. Worthy of 10 Stars for this dish!
