Ingredients
- 4 large Russet baking potatoes (about 10-12 oz each)
- 2 tbsp olive oil, plus more for rubbing
- 1 tbsp butter
- 1 medium yellow onion, finely diced
- 2 cloves garlic, minced
- 12 oz mixed mushrooms (cremini, shiitake, oyster), sliced or roughly chopped
- 1/2 cup vegetable broth or dry white wine
- 1/2 cup sour cream or crème fraîche
- 1/4 cup whole milk or heavy cream
- 1 cup shredded sharp cheddar cheese, divided
- 1/2 cup grated Gruyère or Parmesan cheese
- 2 tbsp fresh chives, finely chopped, plus more for garnish
- 1 tbsp fresh thyme leaves, chopped
- Salt and freshly ground black pepper to taste
Instructions
- Preheat oven to 400°F (200°C). Scrub potatoes clean and pat dry. Pierce each potato several times with a fork. Rub lightly with olive oil and sprinkle with salt. Bake directly on the oven rack for 60-75 minutes, or until very tender when squeezed.
- While potatoes bake, prepare the mushroom filling. Heat 2 tbsp olive oil and butter in a large skillet over medium-high heat. Add diced onion and cook until softened, about 5 minutes.
- Add minced garlic and mushrooms to the skillet. Cook, stirring occasionally, until mushrooms release their liquid and turn golden brown, about 8-10 minutes. If using, deglaze with vegetable broth or white wine, scraping up any browned bits from the bottom of the pan, and cook until liquid has mostly evaporated.
- Season the mushroom mixture with salt, pepper, and fresh thyme. Remove from heat and set aside.
- Once potatoes are baked, carefully slice each potato in half lengthwise. Scoop out the fluffy potato flesh into a large bowl, leaving about 1/4 inch of potato in the skins to maintain structure. Be careful not to tear the skins.
- Add the cooked mushroom mixture, sour cream, milk, 3/4 cup of the cheddar cheese, and all of the Gruyère (or Parmesan) to the bowl with the potato flesh. Mash gently with a fork or potato masher until well combined but still slightly chunky. Season with salt and pepper to taste, and stir in the 2 tbsp chopped chives.
- Spoon the potato and mushroom mixture back into the empty potato skins, mounding it high. Place the stuffed potatoes on a baking sheet.
- Return the stuffed potatoes to the oven and bake for another 15-20 minutes, or until the filling is heated through and lightly golden. Sprinkle the remaining 1/4 cup cheddar cheese on top during the last 5 minutes of baking, if desired, until melted and bubbly.
- Garnish with extra fresh chives before serving. Serve hot and enjoy your ultimate stuffed baked potatoes!
