The safest “homemade” crested gecko food starts with a commercial complete gecko diet powder, mixed with water and, if you like, a spoonful of ripe fruit puree. Recipes built from scratch are hard to balance for calcium and vitamins, so use them with care and talk with a reptile vet if your gecko is young, thin, or breeding.
Why most keepers start with a complete diet
Crested geckos eat both fruit and insects in the wild. Complete powdered diets (sold by several reptile food companies) are formulated to supply protein, calcium, and vitamins in one mix, which makes feeding simpler. Mix the powder with water to the consistency of ketchup or applesauce, and serve a small dish.
Simple mix-ins you can prepare at home
- Ripe mango, papaya, fig, or banana, mashed to a smooth puree. Offer a teaspoon or two stirred into the powder.
- Baby food fruit purees with a single ingredient and no added sugar, starch, or citrus. Check the label.
- Insects such as small crickets or dubia roaches, gut-loaded and dusted with calcium, once or twice a week.
A basic weekly routine
- Mix a fresh dish of complete diet two or three times a week (daily for babies).
- Add fruit puree to some of those meals for variety.
- Offer insects once or twice a week.
- Remove uneaten food after 24 hours. Wash the dish with hot water.
Foods to avoid
- Citrus fruit, which is acidic.
- Avocado and rhubarb, which are toxic to many animals.
- Anything with added sugar, salt, or spices.
- Bread, dairy, and human leftovers.
Storage
Mixed food spoils quickly in a warm, humid enclosure. Freeze unused puree in ice-cube trays and thaw a small cube as needed. Refrigerate mixed diet for up to a day or two and discard anything that smells sour.

Bottom Line
Skip the guesswork: use a complete gecko diet as the base, add fruit puree as a flavor boost, and give gut-loaded insects regularly. If your gecko loses weight or has trouble climbing, call an exotics vet.
