in pasta.
In Pasta, Vegetable Broth Soup provides the base liquid that everything else builds on. The right replacement needs comparable umami and body.

adjustment for this dish
Chicken broth or bouillon soup swaps 1:1 for the broth half of the cooking liquid, but its higher sodium means you should salt the pot to only half the usual level and taste the reserved starch water before you toss it to emulsify. The collagen in chicken broth makes the sauce cling a touch heavier to long noodles like linguine.

adjustment for this dish
Stock soup swaps 1:1 but is typically unsalted, so you can salt the cooking water to the usual 1 teaspoon per quart without overseasoning. The gelatin thickens the reserved liquid as it cools, giving you extra body to emulsify into the sauce so it coats every noodle without needing extra butter.

adjustment for this dish
Chicken broth cubes soup swaps 1:1 reconstituted, but cube sodium can hit 1000 mg per cup — dilute further to 1 part cube broth, 3 parts water for noodle cooking. The concentrated glutamates help the sauce cling to short shapes like penne, but skip salting the water entirely.

Chicken Broth
10.01 cup : 1 cup
Light and savory; most versatile broth swap but not vegan, adds more body than veggie broth
10.0
adjustment for this dish
Chicken broth swaps 1:1 and brings a light fat layer that helps emulsify oil-based sauces onto the noodle; reserve 3/4 cup of the cooking liquid as usual. Its flavor leans toward poultry, so pair with white-wine or cream-based sauces rather than assertive tomato sauces that would clash with the poultry backbone.

Beef Broth
10.01 cup : 1 cup
Richer and meatier; adds depth to soups but not vegan, use mushroom broth as compromise
10.0
adjustment for this dish
Beef broth swaps 1:1 but its dark color stains the noodle and its assertive flavor fights lighter sauces; reserve it for bolognese or braised-meat pasta where the broth reinforces the sauce. Salt the water by only a pinch per quart because beef broth concentrates quickly as the starch water reduces into the toss.

technique for pasta
technique
Vegetable broth soup replaces part of the pasta water so the noodle picks up seasoning while it cooks and the sauce has something savory to cling to. Cook dried pasta in a 50/50 mix of broth and water; full broth over-salts the starch and makes the bite taste like soup.
Reserve 3/4 cup of the broth-water before you drain, then toss it into the pan sauce one tablespoon at a time to emulsify the fat and coat every noodle. Unlike stir-fry, where broth hits a ripping-hot wok and flashes off in under 30 seconds, pasta uses broth as a slow carrier that hydrates starch over 8-11 minutes and ends up partially absorbed.
Salt the cooking liquid only until it tastes like a light soup (around 1 teaspoon kosher salt per quart including the broth's own sodium), because the starch water you reserve will concentrate as it reduces. Finish with grated cheese off heat so the broth-starch emulsion stays glossy instead of breaking into oil slicks.
pitfalls to avoid
watch out
Don't cook noodles in 100% broth; the dissolved salt and starch combine too aggressively and the pasta tastes muddy rather than al dente with a clean bite.
watch out
Avoid dumping all the broth-water down the drain — reserve 3/4 cup before you drain so you can emulsify the sauce and help it cling to each noodle.
watch out
Don't salt the pot to the usual 'sea-water' level when broth is half the cooking liquid; the broth brings its own sodium and will over-season the starch.
watch out
Skip adding grated cheese while the pan is still over heat; the broth-starch emulsion will break, and you'll get oily puddles instead of a glossy coat.
watch out
Avoid pouring broth in cold at the end to loosen the sauce — warm it first, or the residual starch water will seize and the toss will clump.
