Preheat the oven to 375 degrees Fahrenheit.
Add the cornmeal, almond milk, water, garlic, salt, pepper, thyme, and rosemary to a large mixing bowl and whisk well.
Grease a 9 x 13 inch baking dish (or similarly sized dish) with olive oil, then pour in the polenta mixture.
Bake at 375 degrees Fahrenheit for 60 minutes, pausing halfway to whisk the polenta to incorporate any lumps.
Remove from the oven after 60 minutes and whisk once more to ensure a smooth texture.
Serve hot, or store in an airtight container in the fridge for a few days and reheat before serving.
Makes 6 servings of vegan baked polenta.
