Crushed Pecans tossed with Pasta add crunch and richness as a topping or in pesto. The substitute should have a similar oil content and roast flavor.

adjustment for this dish
Cashews swap 1:1 by volume and are actually better than pecans for a creamy cashew-cream pasta — their 46% fat blends into the reserved starch water to form a glossy sauce that clings to al dente noodles. Toast 5 minutes dry in the skillet, soak 20 minutes for a blended sauce, or coarse-crush for a toss-in topping.

Pistachios

Different color and flavor; works in baking

adjustment for this dish
Pistachios at 1:1 make a vivid green pesto — blend with basil, grated pecorino, olive oil, and a ladle of starchy pasta water to emulsify. Their grassy note pairs with lemon and pepper. Toss cooked noodles 90 seconds off heat so the sauce clings without breaking into a greasy puddle.

Almonds

Milder flavor, firmer texture; toast for depth

adjustment for this dish
Almonds swap 1:1 and dominate a Sicilian-style pesto — blanched whole, toasted 6 minutes in a dry 10-inch skillet, crushed coarse with garlic and a ladle of reserved starchy pasta water. Their lower oil content (54% vs pecans' 72%) keeps the sauce lighter; add 1 extra tbsp olive oil to emulsify.

Peanuts
10.01 cup : 1 cup
Sweeter and softer; great in Asian dishes
10.0
adjustment for this dish
Peanuts at 1:1 turn the dish into a noodle-bowl style — crush coarse, toss with chili oil, soy, and reserved starchy water to emulsify. Their legume earthiness wants rice noodles or wheat spaghetti cooked 1 minute short of al dente, finished 90 seconds in the pan so the coat clings without greasing.
05
Walnuts
10.01 cup : 1 cup
Closest swap; slightly more bitter, same crunch
10.0
adjustment for this dish
Walnuts swap 1:1 but their tannin needs counter-balance — add 1 tsp cream to the emulsified sauce or the bitterness edges the grated cheese. Toast 4 minutes in the dry skillet (not pecans' 4 minutes either, but watch closer), coarse-crush, and toss with noodles and reserved starchy water in the final 90 seconds.

technique
Pecans in pasta live or die on their oil — drop them into a dry 10-inch skillet over medium heat and swirl 4 minutes until the pan smells like caramel, then immediately tip onto a plate so the residual heat doesn't scorch them. Coarse-crush (not powder) to roughly lentil-size so they cling to the noodle ridges without sliding off.
Reserve 3/4 cup of the starchy cooking water BEFORE you drain — this is the emulsifier that binds the pecan oil to the sauce; without it, you get a greasy puddle and naked pasta. Cook the pasta 1 minute short of al dente and finish it in the pan with butter, 2 tablespoons of the pasta water, and the toasted pecans, tossing 90 seconds so the starch thickens and coats every strand.
Grated pecorino goes on at the end, off heat, or it seizes into rubber. Unlike pecans in salad, where acid from vinaigrette softens their crunch over 10 minutes, pasta pecans get added at the last toss so they retain bite.
