Penne Arrabbiata

Bring salted pasta water to boil. Cook pasta. In a skillet, heat olive oil. Add chopped garlic cloves and saute until golden brown. Add red pepper flakes and cook until they toast for a few minutes. Now add tomato paste and cook until it depends in color, for a few minutes. Add canned, crushed tomatoes and cook for a few minutes, then add dried basil, salt, and pepper. Season to taste. Add fresh basil and simmer until sauce thickens and reduces. Finally, add spinach and cook until it wilts. Simmer for another 5 minutes. Add drained pasta to sauce, reserving about 3 tbsp of the pasta water and adding it all into the sauce. Stir until pasta is fully mixed in with the arrabbiata sauce. Garnish with more chili flakes, fresh basil, and flaky sea salt.
