Step 1

Preheat oven to 300℉. Line a rimmed sheet pan (or two) with parchment paper. Set aside.

Step 2

Slice the tomatoes in half, lengthwise. Arrange on the sheet pan(s), cut-side up, so that the tomatoes are close together but not overly crowded.

Step 3

Drizzle the tomatoes with olive oil then shimmy around in the pan until all are just coated with oil. Season lightly with salt and pepper.

Step 4

Roast for 2-3 hours, until the tomatoes begin to dry out and shrivel in on themselves, but still retain some juice inside. The timing will vary depending on the size/variety of your tomatoes.

Step 5

Remove from the oven and cover the pan with aluminum foil until cooled, at least half an hour. Use right away, or cover with olive oil and store in the fridge.
