Excellent. Delicious. Followed directions exactly except that my portions were off a bit: 16 ounces polenta; 32 ounces marinara (still used half). Plus, served as a main dish, would not serve eight...at least not in my household. My sixteen-ounce tube of purchased polenta stated four total servings on the nutritional label and that is what this casserole comfortably serves: four. We had a tossed Greek-style salad and green beans on the side. We will definitely have this again. We would like to try adding some veggies to make a total one dish meal: zucchini; onions; tomatoes; peppers?
