Easy Appetizer: Polenta Discs
Baked polenta discs are one of my favorite vessels to use for appetizers. They’re easy to make and are a healthier, more satisfying option than crackers or chips.
You can buy a tube or polenta at almost any grocery store. It’s usually either in the Italian foods section (with jarred sun-dried tomatoes and canned tomatoes) or it’s with the grains (tucked on a shelf below quinoa and cooked rice packets).
To transfer that tube into discs is incredibly easy: Slice it up into 1/2-inch thick discs, bake them off, and you’re ready for topping. Because polenta is gluten-free and vegan, I can serve them to just about anyone.
What Healthy Vegan Toppings Can I Put on Polenta Discs?
The polenta discs are a blank canvas for toppings. Besides the Vegan Wild Mushroom Ragout in this recipe, there are plenty of other healthy plant-based toppings you can use. I love Oil-Free Sun-Dried Tomato Pesto or Sweet Heat Tomato Jam. You can also do Roasted Garlic White Bean Spread and Caramelized Sweet Onions. Heck, even store-bought hummus or a quick tomato basil bruschetta will work.

What is Ragout?
Ragout refers to a hearty French stew. It translates from ragoûter, meaning: “to revive the taste”. Traditionally made with chunks of meat, hearty chunks of mushrooms make a satisfying plant-based substitution. The mushrooms are browned and stewed until full of umami flavor. A splash of white wine and fresh thyme add a pop of flavor.
The ragout is thickened with gluten-free brown rice flour. Nutritional yeast adds creaminess – without any dairy or saturated fat.

What Mushrooms Can I Use in this Vegan Mushroom Ragout?
For the best flavors and interesting textures, mix and match with a variety of mushrooms in this vegan ragout. I used creminis and Velvet Piopinni for this recipe, but explore what’s available at your local farmers market. There is huge diversity in the mushroom family. Your location will offer unique varieties due to the weather and season.
These make delicious finger-food for a summer cocktail party. Or serve them as a fun tapa at an Mediterranean-inspired dinner party. Mushrooms rule because Plants-Rule!




Chef Katie’s Plant-Basd Cooking Tips:
Cleaning and Handling Mushrooms: Food science experiments have shown it’s okay to wash your mushrooms under running water. Use your hands to vigorously remove any loose grit or silt from the mushrooms. If using large Portobello mushrooms, use a spoon to scoop out the gills (which are watery and have an off-putting black color). Use a knife to slice big beef mushrooms (like cremini and white button).
Make Ahead: If making this for a party, you can make both components ahead of time and store them separately. To assemble and serve, reheat the polenta discs in a 350F oven for 8-10 minutes. Microwave or simmer the ragout, covered, 3-5 minutes, until hot. Portion the ragout on the discs and garnish with parsley up to 30 minutes ahead of time. You can keep the assembled discs warm in a 225F oven for up to 30 minutes.
Celiac Concerns: Double-check that the wine you use is certified gluten-free.

Baked Polenta Discs with Vegan Wild Mushroom Ragout
Ingredients
- 1 18-oz tube polenta
- 1 onion diced
- 16 ounces cremini mushrooms sliced
- 4-6 ounces mixed wild mushrooms sliced or torn into large chunks
- 3 garlic cloves minced
- 1 tablespoon fresh thyme minced
- 2 tablespoons brown rice flour
- ¼ cup dry white wine
- ½ cup unsweetened non-dairy milk like almond or soy
- 1 tablespoon nutritional yeast
- ½ lemon juiced
- 2 tablespoons chopped fresh parsley
Instructions
To bake the gluten-free Polenta Discs:
- Preheat your oven to 350°F and line a 9×11 baking sheet with parchment paper or a non-stick baking mat. Remove the pre-made polenta tube from its packaging. Slice into ½-inch thick discs. Place the discs on the pre-lined baking sheet and bake 30 minutes. Flip after the first 20 minutes. When done, remove from the oven and keep warm.
To make the Vegan Wild Mushroom Ragout:
- In a large heavy skillet, sauté the onions and mushrooms over high heat until the mushrooms are brown and have released most of their moisture, about 15 minutes. Add the garlic and thyme and saute until the garlic is soft, 2-3 minutes.
- Add the brown rice flour and cook until no longer white, about 1 minute.
- Pour in the wine and cook until evaporated.
- Pour in the non-dairy milk and nutritional yeast. Reduce the heat to low and simmer until thick and creamy, about 7-10 minutes.
- By now, the polenta discs should be done baking. If they aren’t, keep the ragout simmering on low heat until the polenta is ready. If the ragout starts to dry out, add 1-2 tablespoons of water, as needed.
To assemble and serve the Baked Polenta Discs with Creamy Wild Mushroom Ragout:
- Remove the Wild Mushroom Ragout from the heat. Stir in the fresh lemon juice and half of the parsley. Season to taste with salt and pepper.
- Portion a heaping spoonful of the ragout onto each of the polenta discs. Garnish with extra parsley and serve.

There is a problem with the directions. You’ve repeated some steps, I think. You’ve added the flour twice, the milk twice, etc… Any chance of getting a corrected version? Thanks.
Thanks so much, Suzanne! I fixed the recipe. Hopefully this is much clearer and easier to follow.
