Instructions

  1. Step 1: Preheat oven to 400°F. Place 8 whole garlic cloves on a baking sheet, drizzle with 1 tbsp olive oil, and roast for 20 minutes until soft and golden.
  2. Step 2: Meanwhile, toss 6 halved roma tomatoes and 1 small finely chopped onion with 3 tbsp olive oil, 1 tsp salt, 1/2 tsp black pepper, and 1/4 tsp red pepper flakes on a separate baking sheet. Roast in the oven alongside garlic for 20 minutes until tomatoes soften and caramelize.
  3. Step 3: Bring a large pot of salted water to a rolling boil. Add 12 oz spaghetti and cook for 8-10 minutes until al dente. Drain, reserving 1/2 cup pasta water.
  4. Step 4: Squeeze the roasted garlic cloves out of their skins into a blender with the roasted tomatoes and onion. Blend until smooth.
  5. Step 5: Pour the sauce into a large skillet over medium heat and simmer for 5 minutes, stirring occasionally. Add reserved pasta water in 1/4 cup increments if sauce is too thick.
  6. Step 6: Add cooked spaghetti to the sauce, toss well to coat. Stir in 1/2 cup chopped fresh basil.
  7. Step 7: Serve topped with 1/2 cup freshly grated Parmesan cheese.
