Ingredients

  • 10 plum tomatoes Choose a tomato variety with more flesh and less seeds.
  • ½ teaspoon Magic Mushroom Powder plus more if needed
  • 3 tablespoons extra virgin olive oil divided
  • 2 tablespoons aged balsamic vinegar
  • 2 tablespoons chopped fresh herbs (Italian parsley, basil, oregano, chives, etc.) optional

Instructions

  • Heat the oven to 400°F with rack in the middle. While the oven is heating up, wash and pat dry the Roma tomatoes and cut them in half lengthwise.
  • Line a rimmed baking sheet with parchment paper or aluminum foil. Arrange the tomatoes in a single layer, cut-side up, on the prepared baking sheet.
  • Lightly sprinkle Magic Mushroom Powder on the tops of the tomatoes. Drizzle 2 tablespoons extra virgin olive oil evenly over the tomatoes.
  • Pop the sheet pan of tomatoes in the oven and roast for about 45 minutes, rotating the tray at the halfway point to ensure even cooking. The tomatoes are done when they’re a little brown on the edges and shrunken a bit.
  • Drizzle on some aged balsamic vinegar, the remaining 1 tablespoon of extra virgin olive oil, and fresh herbs, if using.

Notes

  • You can make your own Magic Mushroom Powder or buy it online at The Spice Lab or on Amazon.
  • Air fryer instructions: Air fry them 375°F for about 25 to 30 minutes or until browned on the edges and most of the juices have evaporated. 
  • Leftover oven roasted tomatoes can be stored in an airtight sealed container in the fridge for up to 4 days. You can also freeze them in a sealed container for up to 4 months.
  • These oven-roasted tomatoes taste amazing as is and I routinely serve them as a quick room temperature side dish or add them to salads for a burst of umami. I also love them on burgers, like my Big-O Burgers and Nomster Burgers.
  • You can also blend the roasted tomatoes to make a simple tomato sauce or you can add some vegetable or chicken broth to make a delicious roasted tomato soup. If you aren’t strictly paleo, you can pop them in your favorite sandwich or on top of a slice of avocado toast!
