A vibrant and flavorful pasta dish featuring a spicy tomato sauce, perfect for a cozy dinner.
Heat the olive oil in a large skillet over medium heat until warm.
Ensure the oil is warm but not smoking to avoid burning the garlic.
Add the garlic and sauté until fragrant.
Stir constantly to prevent the garlic from browning too much.
Add the canned tomatoes, breaking them up with a spoon.
Crush the tomatoes gently to release their juices and create a chunky sauce.
Stir in half of the parsley, red pepper flakes, salt, and pepper.
Adjust the seasoning to taste, keeping in mind the saltiness of the cheese.
Simmer the sauce on low heat, partially covered, for 1 hour, stirring occasionally.
Stir occasionally to prevent the sauce from sticking to the pan.
Cook the penne in a large pot of boiling salted water until al dente.
Reserve a cup of pasta water before draining to adjust the sauce consistency later.
Toss the cooked pasta with the sauce until well coated.
Add a splash of reserved pasta water if the sauce seems too thick.
Serve the pasta topped with grated Parmesan cheese and the remaining parsley.
Serve immediately for the best flavor and texture.
