Bring a large pot of generously salted water to a rolling boil. Cook the fettuccine according to the package directions until al dente (usually about 10-12 minutes). Before draining, scoop out about 1/2 cup of the starchy pasta water and set aside - this is liquid gold if your sauce needs thinning later. Drain the pasta but don't rinse it.

While the pasta is cooking, pat your salmon pieces dry with paper towels (this helps them get crispy). Season generously with salt and pepper on all sides. Heat the olive oil in a large skillet over medium-high heat until shimmering. Carefully add the salmon pieces and cook for about 2-3 minutes per side until they develop a beautiful golden crust but are still slightly pink in the center. Remove to a plate and tent loosely with foil.

In the same skillet (don't clean it - those salmon bits are flavor!), reduce heat to medium and add the butter. Once melted, toss in the minced garlic and cook for about 30-60 seconds until it smells amazing but doesn't brown. Pour in the heavy cream, stirring constantly and scraping up any browned bits from the bottom of the pan. Let it bubble gently for about 2 minutes, then whisk in the parmesan until melted. Add the salt, black pepper, red pepper flakes if using, and lemon juice. Taste and adjust seasonings.

Add the drained pasta directly to the sauce and toss well to coat every strand. If the sauce seems too thick, add a splash of that reserved pasta water to loosen it up. Let the pasta hang out in the sauce for a minute to absorb some of that flavor.

Twirl that creamy pasta onto warmed plates, nestle the crispy salmon pieces on top, and shower everything with chopped parsley and a little extra grated parmesan if you're feeling fancy. Best enjoyed immediately with someone you really like.
