This is my fourth "The Best..." cookbook and I would say it is by far the weakest (compared to Best Recipe, Skillet, and Soups).
My biggest problem with it is that there are a ton of recipes that take a lot more than one dish. A cutting board is a given extra... and maybe a random bowl, but tonight I cooked a recipe that required: My Dutch oven, a cookie sheet, three bowls, and then at the end they tell you to transfer it all to a casserole dish and stick it in the oven. You can argue that the bowls don't count but my idea of a "One dish supper" is just that... one dish.
It is worth noting that in typical "The Best..." fashion, the recipe turned out delightful, but for the first time in my experience with these books I believe the cooking instructions were wrong. Apparently they think that putting a dutch oven in the oven at 450 degrees with 3 cups of broth and whole chicken breasts can cook in 8-12 minutes. They also wanted a "large dutch oven" to be used and instruct you to have the oven rack on the upper middle rack... uh, I don't know how big their oven is but with the lid on my dutch oven it didn't stand a chance at fitting, and I feel I have a stereotypical oven.
Don't get me wrong, there are some great recipes in here, but it seems like this cookbook was rushed rather than properly cared for. If you are a big fan of this series then also be warned that there are a lot of repeats in this one with a couple stand outs (pot pie on the cover is excellent and fun).
All in all, if you are looking to find out what is so great about "The best..." series, start elsewhere. If you are a hardcore fan and just want all of their books... well, as I said, there are some great new recipes in here but I don't think it is worth it.
