Can you cook mushrooms in slow cooker? 

Yes! In fact, cooking them this way keeps all that yummy, juicy flavor inside. If done correctly, they will be the perfect texture and not soggy like you might have thought.

Creamy garlic mushrooms

After mushrooms are removed from crockpot, there will be a decent amount of  liquid left behind. Transfer it to a nonstick saucepan and cook on stovetop over medium heat with a cornstarch slurry (1 tablespoon cornstarch dissolved in 1 tablespoon water). Finish it off by mixing in a little heavy cream until sauce is slightly thick and silky smooth. This can be drizzled on top of the mushrooms prior to serving. 

Variations

Stuffed mushrooms- And you thought this recipe couldn't get any better! Remove the stems and load these mushrooms with chives, cheese, onion, peppers, and/or meat of your choice. Bake them in the oven for a crisp, delicious side dish to share.

Cheesy mushrooms- Many believe cheese makes everything better! If you are a cheese lover, add shredded cheddar, mozzarella, or your favorite cheese over the top until slightly melted and enjoy.

Sautéed mushrooms- If you like your mushrooms more dry and crisp, try sautéing them in a nonstick pan instead.

Add ranch seasoning- Replace other seasonings with 1 packet of dry ranch dressing mix.

Try different herbs and seasonings- Depending on what kind of flavor you want, try adding rosemary, basil, or thyme instead of parsley. You can also do Cajun or Mexican seasonings to go with different main dishes, like Slow Cooker Steak Tacos or tacos with Slow Cooker Taco Meat (Ground Beef).

Add lemon- Mix in a little zest and freshly squeezed juice at the end for added flavor.

Tips and Techniques

Bake or roast mushrooms- Transfer cooked mushrooms to a baking tray that's been lined with aluminum foil and sprayed with oil. Broil in oven until tops are slightly crispy.

Don’t add liquids- Such as broth or milk, because this will add too much liquid and make the mushrooms soggy and soupy.

Use unsalted butter- Because you do not want to overpower the mushrooms with salty flavor.

Use whole mushrooms- And not sliced or chopped mushrooms, because they will got too mushy and lose the right texture if sliced.

Storage

Refrigerate- Leftovers can be stored in a sealed container in the fridge for up to 3 days.

Freeze- This is not recommended because mushrooms don't thaw well and become too soggy and "squishy".

Reheat- In microwave or stovetop.
