Slow cooker mushroom barley soup is a true dump-and-go recipe. The ingredients are rather voluminous, so a 6 quart or larger slow cooker is recommended. Once your pot is set, you are going to slice your mushrooms and dice up your vegetables and put them in the pot. Next you will add the spices and barley. The final ingredient to add is the broth. Just cover over your slow cooker with it's lid and you are all done. The hardest part is cutting the vegetables!
Of course, the most important to step is always to turn your crockpot on and then double check to confirm that it is, in fact, on! I wish I had a dime for each time someone told me they either forgot to turn their slow cooker on, OR they turned it on only to realize much later that it was unplugged!
Barley is a wonderful soup ingredient in that is emits starch naturally during the cooking process. This is why soup with barley in it tends to be so thick and hearty. to balance out the thick, rich soup, I recommend serving this dish with a cool crisp salad or, in colder weather, with a delicious cooked vegetable. Avocado toast is another amazing paring for this soup. It is also perfect served with a nice crusty french bread.
If you have leftovers, they can be stored in airtight containers in either the refrigerator or freezer. They will last for 4-5 days in the refrigerator or for several months in the freezer. Frozen leftovers can be reheated in the microwave, on the stove top or even right back in your slow cooker.
One great way to store leftovers is in a mini food warmer! (here is a different brand). The warmer's insert can be stored in the refrigerator and then transferred to the warmer when you want to reheat. This makes for a super way to transport and reheat leftovers (so awesome to have a warm, homemade soup for lunch at work!).
😉Hints & Hacks
- Looking to save extra time? You can purchase all of the mushrooms needed for this recipe pre-sliced.
- Want to save even more time? Purchase your carrots, celery and onion already cut. While they can often be found in the fresh produce section of your market pre-cut, a more economical way is to purchase them frozen from the frozen veggie section. You can purchase each individually or buy find them all together as Mirepoix.
- Having trouble finding one of the types of mushrooms listed in the ingredients? That's ok! This recipe is delicious with many different types of mushrooms! If you decide to swap mushrooms, we would love to hear about it in the comment section below.
- This is a great make-in-advance recipe. You can assemble all ingredients other than barley and the broth the night before. Barley and broth can then be carefully added at the time you are ready to commence cooking.
- This is a perfect meal for days when your people will be eating at different times. After the cooking time, turn your slow cooker to warm (or have it automatically switch to warm if your slow cooker has this feature) and everyone can have a hot and filling meal, no matter what time they are ready to eat.
- I always recommend the use of a slow cooker liner. Of course, this is an optional step. I like to purchase my liners in bulk for a less expensive per-piece price. Here are the liners I buy.
