Choose similar-sized potatoes
Two potatoes of roughly equal thickness are easier to finish together. Weight is a useful starting point, but a long, narrow potato can soften sooner than a round one of the same weight. Scrub the skins under running water and trim away damaged spots before baking.
Use a rimmed sheet because sweet potatoes can leak sticky juices. Leave them unwrapped so you can check the skin and pierce the flesh easily.
Build a filling that stays in place
Drain and rinse the beans, but keep the tomato juices. They provide the simmering liquid. Cook uncovered until the mixture is thick rather than soupy, stirring near the end so the bottom does not catch. If it dries before the onion is tender, add a tablespoon of water and continue gently.


Season after the simmer
Canned beans and tomatoes vary in saltiness. Start with the listed salt and taste the finished filling before adding more. Lime juice goes in after cooking, giving you a clear point at which to adjust the acidity. Smoked paprika contributes a smoky flavor without adding a hot sauce.
Make-ahead and leftovers
For easier reheating, store the cooked filling and potatoes separately in shallow containers. Refrigerate within 2 hours, or 1 hour above 90°F, at 40°F or colder. Use within 3–4 days and reheat leftovers to 165°F. Open the potatoes before reheating so the centers heat more evenly.
A practical portion check
This recipe makes two main-dish portions. The amount of filling is intentionally generous; serve the extra beside the potatoes rather than forcing it into the skins. For smaller appetites, divide each potato and its filling into two portions.

Notes
Allow about 15 minutes of preparation, much of it during roasting. Total time may approach 80 minutes for larger potatoes. This recipe has not been kitchen-tested; tenderness matters more than the clock.
