Lodge 10.25" cast iron skillet. Barely $20, great quality. Have been using it daily for multiple years (along with an another dozen cast iron things) and I'll probably be using it 20 years from now considering it's pretty much indestructible short of being thrown into a volcano.
Prior to this kept using the typical teflon etc nonstick pans for years which cost more, always got ruined within a year, and majority couldn't be used in the oven.
Cast iron is 🖤
