Keep the simmering liquid with the potatoes
Drain the white beans, but keep the diced tomatoes with their liquid. These preparations serve different jobs: the tomatoes and measured water supply the covered simmer, while the already-cooked beans join near the end. Keep the potato pieces at the stated half-inch size so they can soften in that simmer.
Browning the whole thighs is the first cooking stage. Once the potatoes and liquid go in, settle the potatoes around the chicken and replace the lid. Stir underneath as well as around the pieces when checking the pot, so potatoes touching the bottom do not remain in one place throughout cooking.
Finish the chicken and potatoes before the lemon
Use the method's small splash of water only if the skillet is drying before the potatoes soften. The aim is to maintain the gentle simmer, rather than repeatedly uncovering a dry pan. Keep the drained beans ready for their final warming stage and fold them in carefully so they remain recognizable.
Check a potato center and the thickest part of the chicken independently, using the stated 165°F chicken target. Squeeze in the lemon off the heat once both are ready. Spoon the beans and sauce over each portion so the approximate two-to-three-serving batch is shared with its full accompaniment.
