Is AI good at scaling recipes?

For multiplying quantities, mostly yes, though it sometimes rounds oddly or skips a line. Ask it to show every ingredient, and double check eggs, leaveners, salt and pan size, which do not scale in a straight line.

Can I scale a saved recipe without retyping it?

Yes. With Only Recipes connected, ask "show my banana bread for 12 servings" and every quantity in the saved recipe is scaled from its original yield.

How to Scale a Recipe with AI

Asking ChatGPT or Claude to double a recipe is quick. Here is how to do it well, and the parts of a recipe that need a human check.

By the Only Recipes Team. Updated November 13, 2026.

A prompt that works

Scale this recipe from 4 to 10 servings. List every ingredient with the new amount in the same units, round to amounts I can measure, and tell me if the pan size or bake time should change.

What to check after scaling

Eggs: 2.5 eggs is not a thing. Round, or beat an extra egg and use part of it.
Leaveners and salt: in large batches, scale baking soda, baking powder and salt a little under the straight multiple, then taste.
Pans and time: a doubled cake in a deeper pan bakes longer at the same temperature. Two pans keep the original time.
Units: 16 tablespoons is a cup. Ask the assistant to convert to sensible units, or use the cups to grams converter.

Scale recipes you have already saved

With Only Recipes connected to ChatGPT or Claude, say “show my chili recipe for 8 servings”. The saved recipe is scaled from its own yield, so nothing is retyped. Or use the free recipe scaler without an assistant.
