Preheat oven to 425°F. Rub the potatoes with olive oil, sprinkle with salt, and prick all over with a fork. Place on a baking sheet, and bake in preheated oven for 45-60 minutes, or until a fork pierced through the skin meets no resistance.
Prepare the Mushroom Ragout:
While the potatoes are baking, prepare the ragout.
In a large heavy-bottomed saucepan set over medium heat, heat the butter and olive oil until butter is melted and foamy. Add shallots and saute until soft and translucent, about 5 minutes. Add mushrooms and cook for 10 minutes longer, or until the mushrooms are soft and starting to brown. In a small bowl, whisk together white wine and flour until smooth. Add to the pan along with chicken broth and paprika. Reduce heat to low and simmer, uncovered, for 10 minutes or until thick. Stir in the sour cream and continue cooking for 2-3 minutes to heat through (make sure not to bring to a boil, as this can cause the sauce to curdle). Remove from heat immediately, and stir in dill and parsley. Adjust seasoning with salt and pepper to taste.
Once the potatoes are done, transfer them to a cutting board to cool for 5 minutes.
Cut a slit through the top of each potato, and gently push on the ends to create a small pocket for the topping. Sprinkle the inside of each potato with a little salt.
Ladle a generous amount of mushroom ragout onto each potato, letting the excess spill over the sides and onto the plate (yes, it's messy, but it's the best part!). Finish with a sprinkling of parsley or dill, if desired, and lots of black pepper. Serve immediately.
