Heat things up: Grab a large skillet or a sturdy pot and pour in your olive oil. Heat it over medium heat.
Sauté the onions: Toss in your finely chopped onion. Let them cook until they’re soft and look a little see-through, about 5-7 minutes. This is the flavor base!
Add the spice and aromatics: Now, stir in that crushed red pepper and your minced garlic. Cook for just about 1 minute more until you can really smell that wonderful fragrance. Be careful not to burn the garlic!
Tomatoes to the rescue: Add the whole peeled tomatoes to the pot. This is the fun part – you can gently break them up with your hands (carefully, they're juicy!) or use a spoon.
Season it up: Sprinkle in the sea salt and black pepper.
Simmer down: Bring the sauce to a gentle simmer, then turn the heat down to low. Let it cook for at least 20 minutes, or until it thickens up nicely. The longer it simmers, the deeper the flavor!
Herbal infusion: Just before you’re ready to serve, stir in those lovely torn basil leaves. They’ll wilt down and release their amazing aroma.
Pasta time! While your sauce is simmering, cook your pasta according to the package directions.
Plate it up: Ladle that gorgeous arrabiata sauce over your perfectly cooked pasta.
The grand finale: Sprinkle with grated Parmesan cheese if you’re feeling fancy (and why wouldn’t you be?).
