How much does it cost to make Pasta Carbonara?
About $3.27 of ingredients per plate at US foodservice prices, 19.2% of a $17 menu price. Guanciale and Pecorino Romano are 78.0% of it; the spaghetti is 32 cents. What moves the real cost is the pan: a scrambled sauce means the plate is thrown out and cooked again.

A plate of carbonara is 4 ounces of dry spaghetti, 2 ounces of guanciale, 2 egg yolks, an ounce of Pecorino Romano, and black pepper. That comes to $3.27 at foodservice prices, 19.2% of a $17 menu price, under the 25-35% range most kitchens aim for. The guanciale is $1.80 of it and the pecorino 75 cents, 78.0% between them. The yolks are 30 cents, and the spaghetti just 32 cents, 9.8% of the plate. In most pasta dishes the pasta is the filler that keeps the plate cheap; in carbonara it barely registers, and the cost sits in the pork and the cheese.
That makes the guanciale the lever. At 90 cents an ounce, every extra ounce in the pan adds 90 cents and about 5.3 points of food cost. A cook who puts 3 ounces in the pan instead of 2, because 2 ounces of crisped pork looks skimpy, puts the plate at $4.17, 24.5%. Cheese added by eye drifts the same way: an ounce and a half of pecorino instead of one makes it $3.65, 21.5%. Kitchens that keep to the number portion both before service: guanciale cut into 2-ounce packs, pecorino grated and weighed into 1-ounce cups. Bacon at 40 cents an ounce would bring the plate down to $2.27, 13.4%, but the smoke makes it a different dish, and a menu that says guanciale has to serve guanciale.
Carbonara cannot be made ahead. The sauce is yolks and cheese thickened by the heat of the pasta off the flame, so it is finished to order in the pan in the last minute before it goes out. It does not hold on the pass, and reheated it usually scrambles. Past a point the eggs set into curds that no pasta water can loosen, and the plate is thrown out, all $3.27 of it, and cooked again. One remake for every ten plates sold raises the cost of each plate sold to $3.60, 21.2%, so on a busy night the remake rate moves the food cost more than any ingredient price. That is why many kitchens add cream, which keeps the sauce from breaking, though Romans would not call the result carbonara. The cheaper fix is technique: mixing the yolks and pecorino with a splash of pasta water in a bowl and tossing there, away from the burner.
