"I cooked the entire dish on top of the stove in a Dutch oven. It did seem that I had more sauce than what was shown on the program, but that was a good thing; lots of sauce to cover the noodles. I subbed Greek yogurt for the sour cream, and didn't bother buttering the noodles. All those changes, and it was FANTASTIC!! I'm pretty picky and don't end up picking many recipes to include in my cooking repertoire, but this is going into my regular mix. Flavorful, simple, and restaurant quality. "
