A fuel pellet manufacturing method and a fuel pellet. The fuel pellet manufacturing method comprises: S1. weighing following raw materials according to mass percent: 0-8% of yttrium oxide, 0-10% of aluminum oxide, 0-8% of silicon oxide, 5-80% of zirconium carbide, and the balance being silicon carbide; S2. mixing the raw materials with ethyl alcohol, adding polyethyleneimine, perform ball-milling, and uniformly mixing the materials to obtain a mixture; S3. taking 5-20% of the mixture and uniformly mixing the mixture in ethanol to form a slurry, spraying the slurry over surfaces of rolling TRISO particles, and drying to form powder to be pressed; S4. pressing the powder to be pressed into a core blank; S5. taking the remaining mixture in S2 and pressing same into a tube blank; and S6, assembling the core blank into the tube blank, and performing pressing and densification sintering to manufacture the fuel pellet.
