Translation guide
The English phrase "half-baked" has two main uses: describing something poorly planned or not fully thought through, and describing food that is only partially cooked. The Japanese equivalents differ significantly between these meanings.
To describe an idea, plan, argument, or effort that is incomplete, superficial, or lacking proper consideration.
The most common and versatile equivalent. It means something is half-done, incomplete, or half-hearted. Can be used for plans, efforts, attitudes, and more.

Literally "the finishing touches are weak." Used when a plan or idea lacks thoroughness in its final stages, making it unreliable.

To describe food that is not fully cooked, often with a negative connotation of being underdone or improperly prepared.
Specifically means "half-baked" or "underbaked" for bread, cakes, cookies, etc. It implies the inside is still raw or doughy.
Means "the inside is raw." A straightforward way to say something is undercooked inside.

Literally "half-baked." Less common than 生焼け and can sound a bit technical.
Do not use 生焼け or other cooking terms to describe plans or ideas. It will sound like a metaphor about food, not a natural expression for poor planning. Use 中途半端 or 詰めが甘い instead.
中途半端 is the standard word for anything half-done, while 生煮え is a more vivid metaphor from cooking. 中途半端 is safer and more common.
