Rice Cooker Polenta with Zucchini
Learn how to make perfect rice cooker polenta that’s creamy and delicious with this Italian cuisine-inspired recipe.

Traditional polenta recipes require a lot of stirring, but making polenta in a rice cooker is a breeze! Polenta is made from coarsely ground cornmeal and can be served creamy—or cooled, cut into squares, and then baked or fried. A nice alternative to pasta or rice, it can be seasoned to complement different kinds of cuisine.
How to Make Polenta in a Rice Cooker
Instead of being a slave to the stove, you can “fix it and forget it” in a rice cooker with just three simple steps:
- Add water to rice cooker
- Stir in polenta (and any seasoning)
- Cook on the white rice setting
It’s that easy! The recipe calls for vegan “parmesan”—or what my family calls “shaker cheese”. Here are a couple of ways to make it.
Vegan “Parmesan Cheese”
I often use a recipe I found on Minimalist Baker. It’s super easy. You just blend the following ingredients until they become fine crumbs:
- ¾ cup raw cashews
- 3 tbsp nutritional yeast
- ¼ tsp garlic powder
- ¾ tsp Himalayan cooking salt
This option works best for this recipe. However, some people need to avoid nutritional yeast. If you are one of them, try this next option.
Vegan “Parmesan Cheese” – without Nutritional Yeast
Blend the following:
- ½ cup Brazil nuts or cashews
- ½ teaspoon Himalayan cooking salt
- ½ teaspoon dried basil
- 2 cloves of garlic
The fresh raw garlic option provides an extra kick! Feel free to adjust the measurements in either recipe to find the ratio you like best.
The Perfect Comfort Food
This creamy polenta recipe favors its Italian origins with a simple mix of zucchini, tomatoes, onions, navy beans, garlic, oregano, basil, marjoram, parsley, and the vegan “parmesan” of course! The blend of textures and flavors creates the perfect comfort food!
