Clean the russet potatoes under cold water, scrubbing away any dirt, and then dry them well. Use a fork to poke 6-8 holes in each potato to allow steam to escape during baking.
Lightly coat each potato with olive oil and season generously with salt. Arrange the potatoes on a baking sheet and roast in the preheated oven for 45 to 60 minutes, or until they are fork-tender.
Once the potatoes are done, remove them from the oven and let them cool for about 10 minutes. Carefully cut each potato in half lengthwise, scoop out some of the flesh using a spoon, leaving a sturdy rim to hold the skins together. Set aside the scooped potato for future recipes or mash it for a delightful side dish.
In a mixing bowl, combine the shredded cheddar cheese, black beans, diced cherry tomatoes, garlic powder, cumin, and sliced jalapeños. Season the mixture with salt and pepper, and stir until everything is evenly combined.
Generously fill each potato skin with the cheese and bean mixture, ensuring an even distribution.
Return the loaded potato skins to the oven and bake for an additional 10-15 minutes, or until the cheese is melted, bubbly, and slightly golden.
Carefully take the potato skins out of the oven and let them rest for a few minutes. Top each hot potato skin with a dollop of sour cream and a vibrant sprinkle of chopped cilantro.
Notes
Serve with extra sour cream and cilantro for garnish.
