Home cooks can elevate their weeknight dinner routine today with a dynamic miso-mayonnaise sauce that transforms boneless chicken thighs, roasted brussels sprouts, and leeks on a single sheet pan.

The Power of the Miso-Mayo Condiment

Combining rich, savory miso paste with creamy mayonnaise yields a multi-purpose flavor booster designed to streamline preparation. This versatile spread serves two distinct roles throughout the cooking process, delivering deep umami flavor with minimal active effort.

Achieving Deep Caramelization

When mixed with a splash of soy sauce, the initial miso-mayo blend acts as an effective coating for boneless chicken thighs. This savory marinade thoroughly seasons the meat while promoting ideal caramelization along the edges during roasting.

Assembling the Sheet-Pan Rice Bowl

The high-heat sheet-pan method creates a nutrient-dense vegetable foundation, combining tender roasted brussels sprouts with sweet leeks to build out a hearty meal structure.

Balancing Flavors with Rice Vinegar

To complete the dish, the remaining miso-mayo base is whisked with rice vinegar to add necessary acidity and brightness. Drizzling this tangy finishing sauce over the warm chicken, roasted vegetables, and rice unifies all components into a cohesive, flavorful grain bowl.
