Slow Cooker Barley Risotto With Mushrooms

Making a barley risotto in a slow cooker helps you eliminate all of the stirring necessary for a typical risotto. Soak the dried mushrooms overnight in the vegetable broth for even more mushroom flavor. Serve it with a simple side salad for a delicious meal. The recipe serves 4.


  • 1 (4 ounce) package dried porcini mushrooms
  • 3 cups vegetable broth
  • 2 tablespoons olive oil
  • 1 onion, finely chopped
  • 1 pound button mushrooms, quartered
  • 1/2 teaspoon sea salt, divided
  • 1/4 teaspoon fresh cracked black pepper, divided
  • 1 1/2 cups pearl barley
  • 1 teaspoon dried thyme
  • 3 carrots, peeled and finely chopped
  • 1/4 cup dry white wine, such as Chardonnay
  • 3/4 cup grated Asiago cheese
  • 2 tablespoons chopped Italian parsley


  1. The night before making your risotto, bring the vegetable stock to a boil in a small saucepan. Add the dried mushrooms. Cover and allow it to cool on the countertop. Then, refrigerate the mixture overnight.
  2. In the morning, heat the olive oil over medium-high heat in a large saute pan. Add the onions and cook, stirring occasionally, until they are soft, about five minutes.
  3. Add the mushrooms, 1/4 teaspoon of the salt, and 1/8 teaspoon of the pepper. Cook until the mushrooms are soft, about five minutes more.
  4. Remove the rehydrated mushrooms from the broth and chop them finely. Put them in the crockpot, along with the broth, the onions and mushrooms, the pearl barley, thyme, carrots, wine, and the remaining 1/4 teaspoon of salt and 1/8 teaspoon of pepper. Stir to mix.
  5. Cover the slow cooker and cook on low for six to eight hours or high for three to four hours.
  6. Stir in the Asiago cheese and parsley. Serve immediately.


To make a vegetable risotto instead of the mushroom risotto:

  • Don't use the dried porcini or button mushrooms.
  • Instead of steeping the mushrooms the night before in vegetable broth, just add it to the slow cooker in the morning.
  • Saute the onions by themselves and add them to the slow cooker with the other ingredients.
  • Leave out the mushrooms. Instead, add one zucchini that has been chopped and one cup of cubed butternut squash.
  • Replace the wine with the juice of two lemons.
  • Thirty minutes before cooking is done, stir in 2 cups of peas.

To make this recipe vegan, leave out the Asiago cheese. You can replace it with a vegan cheese, or even stir in some nutritional yeast over the top to give it a cheesy flavor.

Barley, Black Bean, and Corn Casserole

This recipe calls for a vegan shredded cheese, such as soy or hemp cheese. If you aren't vegan and eat dairy-based cheeses, feel free to substitute with Monterey Jack or cheddar. This casserole makes a meal all by itself, or you can add a fruit salad on the side to help cool down the spices.
