Pre-heat oven to 400 degrees F.

Pierce cleaned potatoes with a fork in 3-4 places and, for crispy skin, rub with a teeny bit of oil. Bake on a foil lined baking sheet for approx. 40 minutes or until insides are hot and fluffy. Alternatively you can microwave until beginning to soften, about 5 minutes. Flip and continue to microwave in 5 minute intervals, until tender when pierced with a knife. Set aside to cool slightly.

Heat 1 TBSP butter in a large pan over medium-high heat. When butter begins to bubble, add mushrooms and cook, stirring frequently, until they start to brown and soften, about 7 minutes.

Reduce heat to medium and add shallot and remaining butter to pan. Cook until shallot softens, about 1 minute. Add wine and cook until evaporated, 1-2 minutes.

While mushrooms cook, arrange potatoes close together on a baking sheet. Cut across the top, lenghtwise, and gently squeeze in sides of potatoes to puff up the middle, pulling outwards slightly to reveal more of the fluffy potato center. Sprinkle with Cheddar and bake until warmed through and cheese is golden brown, about 5 minutes.
