Although nopal cladodes are a valuable bioactive compound source, they have historically been underused. This review draws a parallel between quantitative and qualitative data from the most outstanding scientific research concerning nopal cladodes in the last five years by implementing a bibliometric analysis. Italy, Mexico, Brazil, and Morocco accounted for approximately 55% of the 111 articles selected for this review. Nopal cladodes are a great source of nourishing ingredients such as mucilage, pectin, insoluble fibers, minerals, ascorbic acid, and bioactive compounds such as carotenoids (e.g., β-carotene, lutein, and cryptoxanthin), flavonoids (e.g., isorhamnetin, quercetin, rutin, and catechin), phytosterols (e.g., β-sitosterol and β-campesterol). Additionally, they offer technological benefits as a food ingredient, allied to good sensory acceptability. The findings suggest that medium-aged cladodes (20 days) have the highest concentration of soluble fiber, protein, and bioactive compounds, rendering them the optimal maturity stage for consumption and processing. Therefore, nopal cladodes can be exploited for several industries, including biotechnology, cosmetics, and pharmaceuticals, and they have attracted attention as a promising ingredient for the food industry in the concept of the next generation of innovative and functional vegetable foods.
