re: How many here cook a lot and get by fine with just one oven?

I use both ovens regularly no matter the number of people. I used two tonight for two people. Adding a warming drawer.

My mother and sister have 3 ovens and a warming drawer. I'd add a third if I had a good spot. We cook a lot, though.

The last time I had one oven I lived in an apt shortly after college.

Think about the foods you cook and how many folks you may be feeding. Your cooking habits should give you your answer. Many folks get along with one. One would drive me crazy.
