Polenta casserole.
Why I ❤️ it
I have to tell you that this is one of my all-time favorites; there are a lot of Mediterranean flavors to this, perfect for a late lunch on a lazy weekend (or, as we call it, "dunch"). Just add fresh salad, some freshly-baked bread (or just reheat it in the oven), and some white wine for an easy yet refined light, gluten-free dish.
Don't be afraid of the multiple steps. It looks more complicated than it really is, and remember, this is almost a one-dish meal, so there won't be much slaving over the stove. I, for one, will definitely be cooking this often.

Top tips
- If you don't have peeled tomatoes, just make a superficial cross cut at the bottom of thetomatoes and dunk them in abundant boiling water. Remove from the water when the peel starts to come off and finish peeling.
- If the polenta is sticking to your spatula or fork just grease the spatula with olive oil, the polenta will slide right off.
- You can use ground cornmeal instead of polenta too, but the texture and consistency will be a bit different.

Serving suggestions
Serve with fresh, green salad, olives, and warm bread, or this lovely halloumi salad.
Variations
You can add two layers of mozzarella cheese to the casserole if you don't need the dish to be vegan. You can also sprinkle some grated parmesan cheese for extra flavor.
You can add some Italian sausage removed from the case to the mushrooms when you sautee them if you want to add meat to the casserole.
If you can have dairy in your diet, you may also love this spinach casserole (with mushroom and quinoa).

Is the ratio of Polenta to Water correct? I usually make it a 1:4 ratio. With close to a 1:1 ratio, the result is extremely course and not something that can be eaten -- even if you cook it for a long time.

It worked for me. Bear in mind that the vegetables release some water while baking.

Hi, I'm a new vegan and I'm loving your vegan recipes. Can you tell Me how long to leave this in the oven for?

About 20 mins, or until the top is light golden.

Hello Aunt Clara.
Is polenta the same thing as cornmeal?
I want to try this recipe.

They're close, but not the same. You can find polenta in the grain section of the supermarket (or ask).

Hi!! Hats off to you for this website and its contents! I was born in th US but my family is originally for DR, as well as my husband. I have to say the first recipe that I tried was Pasteles en hoja. To say the least compliments did not stop all night my family loved it. My hubby said they are better than his moms lol if that says how GREAT they are. FYI just printed a few more recipes to try for New Years!

I love this recipe, and look forward to trying my own variation!! Polenta is one of my favorites. I am coming to the DR next week (Sosua area) to explore the idea of living there. Where are you located?? One of the reasons we are leaving Florida (to either the DR or Ecuador) is we want a more sustainable lifestyle, in a more friendly, healthy environment. I would be very interested in finding organic sources (I intend to garden too!) for fruits and vegetables.Your site has been inspiring, and I enjoy each new entry. Thanks!!

I live in PuntaCana, and I really have no experience living in the Sosua area. I would suggest that you visit our friends at DR1.com and enquire there.
