These slow cooker marinated mushrooms are delicious and versatile. Serve them as a standalone side dish or incorporate them into your favorite sauces and gravies.

Cooked Mushrooms

My husband and I enjoy mushrooms any way they’re presented. We like raw mushrooms in salads or cooked ones in any prepared food.

And we especially enjoy adding them to spaghetti, pizza, casseroles, and other savory dishes.

Mushrooms add so much flavor and texture to foods. They also absorb other flavors, which is one of the reasons we enjoy putting them in gravies and sauces.

Although raw mushrooms are tasty and have a unique texture, cooking them brings out the depth of their flavor. They provide a combination of meaty and nutty added to whatever you cook them with.

When I cook mushrooms, I like to season them with flavorful spices and sauces. The ones I use for this recipe are among my favorites.

You get the blend of chicken and beef flavoring, but neither is overpowering. The Worcestershire sauce adds a bit of zing to them.

Garlic and onion powder are good in a lot of different savory dishes, and this is no exception. The butter takes it to the next level of deliciousness.

Are Mushrooms Healthier When Cooked?

According to U.S. News, the same volume of cooked mushrooms has more nutritional value than raw. That’s because they’re mostly water, so the cooked ones have more concentrated nutrients.

Mushrooms are also more digestible after they are cooked. You get more of the nutrients, such as protein, vitamins, and minerals.

According to ScienceDirect, mushrooms contain anti-inflammatory properties that help prevent many types of disease and disorders.

How to Make Slow Cooker Marinated Mushrooms

Of course, you’ll need a slow cooker. I used one of my small-ish Crockpots to make these mushrooms.

It needs to be big enough for the raw mushrooms to fit but small enough that they’re not too spread out on the bottom after they’re done.

Combine everything except the mushrooms in a medium-size mixing bowl. Whisk the liquid until everything is mixed.

Clean the mushrooms. This is the most time-consuming part of the process, but it’s super easy.

In the past, I rinsed them under running water. I eventually learned that this doesn’t clean them very well.

Now I use a wet paper towel and wipe off each mushroom. It takes me about 5 seconds per mushroom, so it’s not that long.

After I spray the inside of the slow cooker, I dump in the mushrooms.

Then I pour the liquid and seasoning mixture over them.

Don’t worry about submerging the mushrooms because they’ll sink down into the liquid as they cook.

Finally, it’s time to turn the slow cooker on and let it do all the work.

The mushrooms take about 2-3 hours on high or 4-5 hours on low to get just right.

How to Serve Marinated Cooked Mushrooms

As I already mentioned, these mushrooms are versatile. You can serve them as an appetizer or make them a side dish for any meal.

Add them to gravy that goes on meat, potatoes, or rice. The enhanced flavor of the marinade kicks any gravy or sauce up several notches.

They’re also delicious when added to spaghetti sauce. Or you can slice them and put them on pizza alongside these yummy roasted tomatoes.

We like them on baked potatoes. In fact, with a little bit of butter, these mushrooms, and some shredded cheese, a baked potato becomes a full meal.

Make enough to have leftovers. Have some right after they’re done and refrigerate or freeze the rest for another meal or two.
