Tomatoes – you can use any kind of tomatoes you prefer. I love making this with cherry or grape tomatoes, sungold tomatoes, or even chopped heirloom and beefsteak tomatoes!
Garlic – a good sauce always has some garlic, imo! Adding whole cloves straight to the sheet pan is easier, and helps bring in a beautiful roasted garlic flavor.
Olive Oil – I recommend extra virgin olive oil for max flavor and benefits.
Balsamic Vinegar – not pictured above, but my favorite versions of this sauce always include balsamic vinegar for a touch of sweetness and even more depth of flavor.
Seasonings – the tomatoes are roasted with Italian seasoning, salt, and pepper.
Fresh Basil – I kind of hate to say it, but truly fresh basil makes the biggest impact here. It massively elevates and rounds out the flavor when you blend it into the sauce at the end.
