I recommend using a Dutch oven because it just comes out extra delish and the bread crumb crust comes out perfect, but honestly you can use a casserole dish or baking pan, it doesn't really matter.
You can use shells, spirals, or elbow macaroni.
You can use hot sauce instead of taco seasoning.
You can use regular or heavy whipping cream for this recipe, it makes little difference. Also the spice situation is definitely on a scale. Some people like plain-tasting mac and cheese and some like it spiced up a bit. Mine is somewhere in the middle, I'd like to say.
