Step 1

Prepare tomatoes by washing.

Step 2

Slice tomatoes as uniformly as possible to a maximum of 1/4" thickness. and lay them out on a cookie sheet in a single layer.

Step 3

Heat your oven to a low temperature. You can potentially set it from 160 up to about 255 Fahrenheit, but I recommend going with the lowest possible temperature to prevent burning.

Step 4

Drizzle a small amount of olive oil over them (optional) and sprinkle lightly with salt.

Step 5

Season with spices if desired.

Step 6

Place baking sheets into the oven and bake, watching them carefully so they don’t burn. They'll be in there for a while--possibly all day.

Step 7

If desired, flip tomatoes in the middle of the drying time (around the 3 hour mark) to make them dry a bit faster.

Step 8

The tomatoes are done when they are dry but still pliable (not moist or sticky).
