If someone were to ask me to rank the order in which to buy them…
12” skillet
7 quart dutch oven (the lid fits a 12” skillet)
Pizza pans (I have two but wouldn’t mind two more for when I’m baking large batches of mini-pizzas, cookies, etc.)
Bread pans (I have two)
2 quart dutch oven (I have two. Great for heating leftovers)
4 quart dutch oven
Drop biscuit pan (for making burger buns and mini pies and cakes)
9 quart dutch oven (for making broth, though you could use a 7 quart)
10” skillet
8” skillet
