I've been baking polenta for years- it's an absolute breakthrough! One crucial thing this recipe leaves out is that you need to salt the water the polenta cooks in, not just at the end! Polenta cooked in plain water is oddly flavorless a way that salting afterwards does to fix. I stir in 1/2 to 3/4 tsp of salt at the very start, whisk the polenta at the 20 minute mark, and then whisk again, adding butter and parm, when done...
I’ve been cooking polenta in the oven for years. One handy tip is to have an oiled sheet pan ready when it comes out of the oven. I always make extra, and after serving, I spread the extra about 1” thick on the sheet pan. It sets up firm while we eat dinner, and can be cut into squares for easy reheating for another meal. Just sauté or grill.
We also having been baking polenta for years, adding salt to cooking liquid, and stirring midway to help things along. But our added trick is half water and half milk. Makes an incredibly creamy polenta!
Perfection!
This recipe is awful. over an hour and a half in the oven.
Tried this in our well seasoned cast iron skillet of 15 years. No issues with clean up. The key to successful dishes (any dish) in cast iron is meticulous maintenance after every use. It takes extra time but worth the effort! No need to purchase expensive cast iron either. We use Lodge cast iron skillets often. Although I do not care for polenta my husband loved this dish! I added a little white pepper with the salt!
