This easy no-stir Slow Cooker Mushroom Risotto gives you creamy, cheesy perfection with minimal effort. Ideal for weeknights or relaxed weekends.

If you love risotto but don't love stirring it for half an hour, this Slow Cooker Mushroom Risotto is about to become your favorite kitchen shortcut!
It tastes just as indulgent as the classic stovetop version, but all you have to do is toss the ingredients into your slow cooker and let it do the work.
Although you can skip it, I usually pan fry the mushrooms and onions first, then simmer it briefly in the white wine before adding to the crock pot - it really adds great flavour.
However, if you don't have time then just throw it all into the slow cooker and stir - it's still delicious.
No stress, no constant attention, just creamy, earthy, perfectly cooked rice every time.
I've made risotto countless ways: on the stove, in the Instant Pot, even in the oven, but the slow cooker method is the one I return to on busy evenings.
We like to serve our slow cooker mushroom risotto with a side salad, like Tomato Onion Salad, Pear and Gorgonzola Salad, or Broccoli Cranberry Salad.

Why You'll Love This Recipe
- Crock pot risotto is easy. You just set it and forget it.
- This mushroom risotto is vegetarian and full of flavor.
- It uses simple, affordable ingredients.
- The slow cooker does the work for you.
- It's perfect for busy weeknights.
Ingredients
- Mushrooms. The main flavor driver. Use chestnut, button, cremini, porcini, or a mix for the best texture and depth.
- Vegetable stock. The liquid base for cooking the rice. Use good-quality stock or homemade for the best flavor. Or try it with homemade Mushroom Stock.
- Arborio rice. The classic risotto rice that releases starch slowly to create a creamy texture. Carnaroli or vialone nano are good substitutes.
- White wine. Adds acidity and brightness. If you prefer to skip alcohol, replace it with extra stock.
- Onion. Builds the flavor base. A yellow or white onion works best. Shallots can be used for a milder taste.
- Olive oil. Adds richness and helps soften the onions and mushrooms. You can substitute butter for a more indulgent flavor.
- Fresh thyme. Adds herbal notes that balance the richness. Dried thyme can be used in a smaller amount.
- Salt and pepper. Essential for seasoning and bringing out the flavor of the mushrooms.
- Parmesan cheese. Adds creaminess and a salty, nutty flavor at the end. For a vegetarian alternative, use vegetarian hard cheese or nutritional yeast.
- Fresh parsley. Brightens the dish and adds freshness before serving.
