1 teaspoon sea salt

20 cherry tomatoes

2 cloves garlic, minced

1 tablespoon plus 2 1/2 teaspoons fresh thyme leaves

1/4 cup olive oil

Coarse salt and freshly ground pepper

1 1/3 pounds spaghetti

1 tablespoon plus 2 1/2 teaspoons sea salt

Preparation

Make the tomato sauce: Heat olive oil in a medium Dutch oven over medium-high heat. Add onion, garlic, and chile; cook, stirring, until soft and translucent. Add tomato paste and cook, stirring, about 5 minutes.

Add beefsteak and plum tomatoes to Dutch oven. Wrap thyme, parsley, basil, and herbs de Provence in a piece of cheesecloth, using kitchen twine to enclose. Add to saucepan and season with salt. Reduce heat to medium-low; cover and cook, stirring occasionally, until thickened, about 3 hours. Remove cheesecloth packet and discard. Using an immersion or standard blender, blend sauce until smooth. Strain sauce through a fine mesh strainer and return to Dutch oven; set aside.

Make the confit: Preheat oven to 150 degrees. Fit a rimmed baking sheet with a rack and set aside.

Place cherry tomatoes in a large bowl and add garlic, thyme, and olive oil; season with salt and pepper and toss to combine. Evenly spread tomatoes on prepared baking sheet and transfer to oven; bake for 3 hours.

To serve: Bring a large pot of water to a boil over high heat. Add sea salt and return to a boil. Add pasta and cook, according to package directions, until al dente; drain.

Meanwhile, place tomato sauce over medium heat and add chile, cheese, and tomato confit; season with cracked black pepper and fleur de sel. Stir to combine. Stir in pasta to coat with sauce and evenly divide between 4 serving plates. Top with basil and serve immediately.
