Turn the oven onto medium heat and add the olive oil to your pot.
Once your oil is hot, add three popcorn kernels.
Wait until all three kernels have popped to gauge the heat of your pot. If they pop immediately, turn your heat down a bit. If they take awhile to pop, turn your heat up a bit.
Once you have your heat to a good spot, add your butter and let it melt.
Also add your salt.
Pour your popcorn kernels into your hot, melted butter. Immediately cover with the lid.
Shake your pot to coat your kernels in the butter and salt.
Again, use this time to gauge your heat. If they're taking awhile to start popping, turn your heat up and vice versa.
Once they start popping, shake every 20-30 seconds to keep from burning.
When the popping becomes infrequent, you can remove the lid and stir the popcorn around a little bit to help the last remaining kernels pop.
Once the popping stops completely, turn the heat off.
Notes
I like to use olive oil and butter but you could also use avocado oil, coconut oil, etc.
