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!
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.
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.
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.
