Sometimes, simple is best when it comes to enjoying seasonal produce. This roasted ratatouille might sound fancy, but itโs essentially just a sheet pan roast of tomatoes, zucchini, eggplant, bell pepper, and onion. Theyโre packed (and I mean PACKED!) onto a single rimmed baking sheet, seasoned with salt, garlic powder, and fresh thyme, then left to roast for 45-60 minutes. Thatโs it! The remaining component for this vegan and gluten free meal is a super creamy vegan polenta. It cooks while the veggies roast, requiring minimal hands-on time. Plus, it makes this vegan meal comforting, cozy, and filling. Letโs whip up a bowl!

Notes on Ingredients and Substitutions
If you cannot find dry polenta, you can use the cooked polenta that comes in a tube instead. Buy enough for 4 servings (check the label) and heat in a pot over medium to medium-low heat with broth or milk until creamy. Add salt and vegan butter as needed. I prefer using a vegan bouillon cube and water instead of broth since it prevents half-used cartons hanging around in my fridge. If you prefer, you can use 2 1/2 cups vegetable broth instead. As for the ratatouille veggies, the traditional mix is what you see reflected in the recipe: tomatoes, eggplant, zucchini, bell pepper, and onion. If you donโt have or donโt like any of those veggies, simple double-up on the others that you do have/like!

The Key to Ensuring Super Creamy Polenta
Over the years Iโve settled on a combination of ingredients and a cooking method that results in super creamy polenta every single time! The most important thing is the ratio of polenta to liquid. I do a 1:4 ratio of polenta to liquid which ensures the polenta has plenty to absorb as it cooks. It keeps it from being stiff or dry. The other important thing is my unconventional cooking method. Rather than standing over the pot whisking continuously, I cook the polenta to a certain point, then cover it, turn the heat down, and let it do its thing undisturbed. This traps the steam inside the pot and helps cook and soften the polenta without it drying out. Lastly, I love using a can of full fat coconut milk as part of the liquid. The fat in the coconut milk amplifies the creaminess.

Tips for Reheating Cooked Polenta
As polenta cools, it solidifies. It can easily be re-heated in a pot over medium to medium low heat with a generous splash of broth or water. Gently mix as it begins to heat up, adding more broth or water as needed to help break up clumps and return it to a creamy state. It can also be microwaved. Add a splash of broth to a microwave safe bowl. Microwave in short bursts, stirring and adding more broth as needed until creamy.

Creamy Vegan Polenta with Roasted Ratatouille
- Total Time: 1 hour 10 minutes
- Yield: 4 servings 1x
- Diet: Vegan
Description
This creamy vegan polenta with roasted ratatouille is the perfect rustic summer meal! A mix of zucchini, eggplant, tomatoes, bell pepper, and onion are roasted together until tender then piled atop a bed of pillowy soft polenta. Each bowl is finished with a drizzle of red wine vinegar and basil to perk up the flavors while a sprinkle of vegan parmesan lends a savory and cheesy element.
Ingredients
for the roasted ratatouille (summer veggies)
- 2 medium zucchini, cut into quarters lengthwise then into 1-inch chunks
- 1 large eggplant, cut into 1-inch chunks
- 1 medium yellow onion, ends removed and cut into 8 wedges
- 1 large red or orange bell pepper, cut into 1-inch chunks
- 12โ16 ounces tomatoes, any variety, cut into a similar size as the other veggies (leave cherry & grape tomatoes whole)
- 1 1/2 teaspoons fresh thyme leaves, finely chopped
- 1 teaspoon garlic powder
- 2โ3 tablespoons olive oil
- Sea salt, to taste
for the creamy vegan polenta and serving
- 1 13.5โounce can full fat coconut milk
- 2 1/2 cups water
- 1 vegan bouillon cube
- Sea salt, to taste
- 1 cup dried polenta
- 4 tablespoons vegan butter
- 1 large handful fresh basil, finely chopped
- Red wine or balsamic vinegar, for serving
- Grated vegan parmesan, optional for serving
Instructions
Preheat the oven to 400 degrees and line a large rimmed baking sheet with parchment paper. Add the chopped zucchini, eggplant, onion, bell pepper, and tomatoes to the baking sheet then sprinkle over the thyme, garlic powder, and a couple of big pinches of salt. Drizzle with olive oil then toss to evenly coat. Arrange the veggies in an even layer (there will be plenty of overlap which is fine!) then place the pan in the preheated oven. Roast for 45-60 minutes until veggies are tender and just beginning to caramelize around the edges.
Once the veggies have been roasting for 15 minutes, add the coconut milk, water, bouillon cube, and a big pinch of salt to a large pot. Bring to a boil over medium-high heat. Once the broth is boiling, pour in the polenta and reduce the heat to medium. Whisk the polenta constantly until it thickens and begins to spurt. This should take no more than 5 minutes. Once it thickens, place the lid on the pot, move the heat down to medium-low, and allow the polenta to cook undisturbed for 15 minutes, covered. After 15 minutes, remove the lid, add the butter, and whisk to allow the butter to melt. Place the lid back on the polenta to keep it warm until ready to serve.
To serve: divide the polenta between four bowls then top with the roasted veggies. Drizzle a bit of the vinegar over the veggies then garnish with basil and some vegan parmesan if desired.ย
Keep leftover polenta and roasted ratatouille in separate containers in the fridge. Enjoy within 4-5 days.ย
Notes
- 2 1/2 cups vegetable broth can be used in place of the water and vegan bouillon cube if you prefer.
- 1/2 teaspoon dried thyme or herbes de provence may be used in place of the fresh thyme.
- If you are not vegan and eat dairy, feel free to use regular butter and parmesan in the recipe. You can also use 1 1/2 cups half and half or whole milk in place of the coconut milk in the polenta if you prefer.
- If you want to change things up, the roasted ratatouille can be enjoyed with cooked pasta instead of polenta.
- If you want to add more plant-based protein, I recommend adding 1 can of cooked cannellini beans or lentils. Drain and rinse them, then add them to the tray with the veggies during the last 5-10 minutes of the roasting time. For even more protein, stir 1 cup of blended silken tofu into the polenta along with the butter.ย
