01 - Bring a large pot of salted water to a boil. Add orzo and cook according to package directions until al dente. Drain, reserving 1/2 cup pasta water, and set aside.
02 - Heat olive oil in a large skillet over medium heat. Add garlic and chili, sauté for 1–2 minutes until aromatic but not browned.
03 - Stir in tomato paste and cook for 1 minute. Add canned crushed tomatoes, sugar, sea salt, and black pepper. Simmer for 10–12 minutes, stirring occasionally, until sauce slightly thickens.
04 - Add drained orzo to the skillet with the tomato sauce. Toss to coat, gradually adding reserved pasta water to achieve a silky texture.
05 - Remove from heat. Stir in torn basil and grated Parmesan. Taste and adjust seasoning as desired.
06 - Serve immediately, garnished with additional Parmesan and chopped parsley if desired.
