The idiomatic expression "a slow burn" describes something that develops gradually, often building in intensity over time. It suggests a delayed reaction or realization that is ultimately powerful or impactful. Think of it like a fire that starts small but eventually grows into a large and intense blaze.
While the phrase uses the literal words "slow" and "burn," it's almost always used figuratively. You're unlikely to hear someone describe firewood as "a slow burn" unless they're also commenting on the metaphorical implications of its gradual combustion.
Register: Neutral
"A slow burn" is a relatively flexible phrase. It can function as a noun, often with a determiner ("a slow burn," "the slow burn"), or as part of a verb phrase ("do a slow burn"). It can be modified with adjectives (e.g., "a satisfyingly slow burn") and can be negated (e.g., "it wasn't a slow burn").
It sounds unnatural to use the phrase too literally or in contexts where the gradual development and eventual intensity are not relevant. For example, describing the speed of a turtle as "a slow burn" would be inappropriate because it lacks the element of increasing intensity or delayed impact.

No, the expression "a slow burn" is almost exclusively used figuratively. While it uses the words "slow" and "burn," it refers to the gradual development and increasing intensity of something, not literal combustion.
While both phrases describe something that happens over time, "a slow burn" implies a build-up of intensity and a delayed but powerful impact. "A gradual process" simply emphasizes the step-by-step nature of the development, without necessarily suggesting increasing intensity or a significant delayed effect.
To avoid misusing "a slow burn," make sure the situation you're describing involves something that not only happens slowly but also builds in intensity or has a delayed, significant impact. Don't use it simply to describe something that is slow or frustrating without this element of growing intensity.
