What is Spaghetti all'Assassina (Killer Spaghetti)?
Spaghetti all'Assassina is a spicy dish from Bari, Italy, where the noodles are uniquely caramelized and cooked directly in the tomato sauce.
The named translates to "Killer Spaghetti" or "Assassin's Spaghetti", which alludes to both the cooking method of "charring" the noodles, and also the spicy heat from the liberal use of chili flakes.
The cooking method results in a rich, bold, and spicy pasta that spicy food lovers are guaranteed to love. It's a bit like making an Italian risotto, but with noodles.
You'll find similarities to Mexican Fideo Noodles, which uses a similar technique of browning the noodles in a pan, then simmering in a flavored tomato sauce.

How to Make Spaghetti all'Assassina (Killer Spaghetti) - the Recipe Method
Make the broth/sauce first by cooking the garlic in oil in a saucepan, then adding the remaining ingredients - tomato sauce, tomato purée, water, and salt and pepper to taste.
It should be fairly brothy in consistency. Simmer for 10 minutes to develop the flavor and keep warm.

For the spaghetti, heat the olive oil in a large cast iron pan to medium heat and bloom the garlic.
Add 2 cups of the tomato sauce to the pan, then spread the dried spaghetti noodles out over the pan for even cooking.
Cook for 3-4 minutes, stirring occasionally, or until the noodles absorb the liquid. The noodles will start to brown on the bottom and get slightly crispy.
You can brown or caramelize the pasta as much or as little as you prefer, stirring lightly as needed. This is a distinct characteristic of Spaghetti all'Assassina.

Add the tomato broth 1 cup at a time every minute or so and simmer, letting the noodles absorb the sauce and soften up to your preference, about 10 minutes for al dente.
Boom! Done! Your Killer Spaghetti is ready to serve. Looks great, doesn't it? Pasta lovers rejoice! This is such an amazing dish. So good.
