Instructions
- Step 1: In a large saucepan, heat 3 tbsp extra virgin olive oil over medium-low heat. Add 4 minced garlic cloves and sauté for 60 seconds until fragrant but not golden.
- Step 2: Stir in 1 can (28 oz) crushed San Marzano tomatoes, 1 tsp dried oregano, and 1/4 cup of the fresh basil. Simmer uncovered for 45 minutes, stirring occasionally, until the sauce thickens and coats the back of a spoon.
- Step 3: While sauce simmers, bring a large pot of salted water to a rolling boil. Add 12 oz spaghetti and cook for 8 minutes until al dente. Reserve 1 cup pasta water before draining.
- Step 4: Toss drained spaghetti with 3/4 cup of the tomato sauce in the pot, adding reserved pasta water 1 tbsp at a time until glossy. Stir in remaining fresh basil and 1/2 cup grated Pecorino Romano cheese until melted and emulsified.
