In a slow cooker, arrange diced sweet potatoes on bottom. Layer chicken on top of sweet potatoes, then top with lemon slices.
In a small bowl, whisk together lemon juice, olive oil, chicken broth, salt and pepper. Pour over chicken. Top with fresh herbs.
Cook on high 5-6 hours or low 7-8 hours.
The Citrus Component
Meyer lemon juice drives this dish, offering a distinct hybrid profile of traditional lemon and sweet mandarin orange that reduces the aggressive acidity often found in standard Eureka lemons. Thinly slicing the fruit directly over the poultry allows volatile aromatic oils in the rind to leach downward during the extended cooking cycle, perfuming the meat far more thoroughly than mere juice extraction can achieve. While conventional lemons yield a sharp, bracing bite, Meyer lemons contain lower levels of citric acid, which prevents the prolonged heat of a slow cooker from turning the sauce unpleasantly bitter.
Thermal Dynamics and Starch
Laying dense root vegetables at the base of the insert vessel creates a physical buffer zone that shields the poultry proteins from direct contact with the heating element. Sweet potatoes contain high levels of complex carbohydrates and amylase enzymes that break down as internal temperatures reach 200 degrees Fahrenheit, releasing natural sugars into the surrounding liquid. This process thickens the modest volume of chicken broth and olive oil into a cohesive emulsion without requiring external roux or starch slurries. Ensuring the potatoes are cut into uniform cubes guarantees they soften at the same rate as the chicken renders its fat.
Aromatics and Fat Distribution
Fresh rosemary and sage release fat-soluble terpene compounds when exposed to heat, meaning the olive oil and rendered chicken fat act as essential extraction agents to carry herbal flavors throughout the dish. Stripping the woody stems from the rosemary prevents unpleasant fibrous textures in the final sauce while allowing the needles to soften completely. When scaling this preparation, maintain a strict ratio of one part citrus juice to two parts low-sodium broth to preserve the delicate balance between acidity and savory depth.
