I used a 3.5 L round casserole dish for this recipe. However, you can also use an 11 x 6 inch (28 x 15 cm) baking dish (like the one in my vegan french toast casserole) or any large oven-safe dish! You may also use a cast-iron skillet. However, their protective non-stick coatings are ruined by acidic ingredients such as tomato sauce, which you may or may not care about!
