Grab a large saucepan and pour in 1/4 cup of the olive oil along with your smashed garlic clove. Set it over medium-low heat and let everything warm up together until you hear a gentle sizzle, roughly 2 minutes. Toss in your red pepper flakes if using. Press down on the garlic to release all those wonderful flavors, but watch carefully—don't let it turn brown or it'll taste bitter. At this point, you can fish out the garlic for a subtle taste, or leave it in if you're a garlic lover.

Pour your canned tomatoes into the pan along with all their liquid. Grab a potato masher or a solid wooden spoon and crush those tomatoes into chunky pieces—no need to make them smooth yet. Sprinkle in about half a teaspoon of salt, then crank up the heat to medium-high. Once everything starts bubbling, dial it back down to keep a very light, lazy simmer going.

Place the lid on your pan but leave it slightly cracked open. Let this simmer gently for 35 to 40 minutes, giving it a stir every so often. You'll know it's ready when the tomatoes have deepened to a rich red color, the sauce has thickened nicely, and you can see oil glistening on top. If it gets too thick before it tastes sweet and developed, just add a little splash of water to loosen it up.

Turn off the heat and give your sauce a 10-minute break to cool down a bit. Set a fine mesh strainer over a bowl and pour the sauce through, using a spoon or spatula to press all those tomatoes through until you've got a beautifully smooth sauce. Pour it back into your pan, give it a taste, and add more salt if needed.

Stir the remaining 2 tablespoons of olive oil into your sauce. Lay that basil sprig right on top and bring everything to a gentle simmer over medium heat. Let it cook softly for about 15 minutes—the basil will wilt down and perfume the whole sauce. When time's up, fish out the wilted basil stem and toss it. Feel free to tear in a few fresh basil leaves for extra brightness. Cover the pan to keep everything warm while you cook your pasta.

Fill your biggest pot with water, bring it to a roaring boil, and salt it well—it should taste like the sea. Drop in your spaghetti and cook following the package timing until it's just al dente with a slight bite. Don't drain it in a colander! Instead, use tongs, a pasta fork, or a spider strainer to lift the pasta straight into your sauce pan. Add a good splash of that starchy pasta water and turn the heat to low. Toss everything together for about 2 minutes until each strand is beautifully coated and glossy.

Twirl the pasta into individual serving bowls and spoon any extra sauce from the pan over the top. Finish with a generous shower of Parmesan cheese if you're using it, and scatter some fresh basil leaves on top. Serve immediately while it's piping hot and dig in!
