Servings 8 Servings
- 3 lbs (1.37 kg) Fresh Tomatoes I like stupice, roma, early girl and/or a variety of heirloom.
- 1/4 C (60g) + 2 Tbs + 1 tsp Extra Virgin Olive Oil divided
- 3-4 Cloves of Garlic large and plump
- 3/4 C (75g) Walnuts
- 1 Tbs Tomato Paste
- 1/2 - 1 tsp Red Pepper Flakes For a more mellow spice, add 1/2 tsp or take it up, using 1 tsp.
- 1 1/2 tsp Fine Sea Salt plus more to taste
- 1 tsp Dried Oregano
- 5-6 Leaves of Fresh Basil optional
- 1/2-1 tsp Sugar optional but helps balance the acidity of the tomatoes. Taste your sauce before adding. If too acidic, add a little sugar.
- For Serving (optional): Favorite Pasta, Pesto, Parm and fresh torn Basil
Preheat oven to 450f (232C) and set oven rack in the center. Line a sheet pan with parchment paper. Set aside.
Remove stems of the tomatoes and slice in half. Place on prepared sheet pan and toss with 2 Tbs of olive oil. Arrange tomatoes evenly on the pan. Place the garlic (skins removed) on a small piece of foil, drizzle with 1 tsp of olive oil and wrap loosely. Place the foil packet on the sheet pan with the tomatoes. Roast the tomatoes and garlic for 25-30 minutes rotating the pan once while roasting. If you have time, the garlic will benefit from another 10 minutes in the oven. The tomatoes should be soft, juicy and with some charring. Remove from the oven and set aside.
At some point while the tomatoes and garlic are roasting, toast the walnuts in the oven on a small sheet pan for 4-5 minutes. This is a high heat for walnuts, so they can burn quickly if left in the oven too long, so keep an eye on them! They'll be golden and fragrant when ready. Set aside to cool.
In the work bowl of a food processor, or blender add the roasted tomatoes and all their juices, garlic, walnuts, tomato paste, pepper flakes, sea salt, oregano and basil if using. Pulse ingredients a few times, then pour remaining olive oil (1/4 C / 60g) in a steady stream while pulsing the blender or processor. Taste for salt and sugar adjustment. Add a few grinds of black pepper if desired. An immersion blender can be used as well.
