Ingredients
- 4 large potatoes
- 150 g fresh button mushrooms
- 1 small onion
- 1 tomato (or 4 cherry tomatoes)

- 20 g butter
- 1 tablespoon olive oil
- 2 tablespoons heavy cream
- A few fresh parsley leaves
- Salt and black pepper to taste
Instructions
Bake the Potatoes
Begin by preheating your oven to 400°F (200°C). Thoroughly wash the potatoes under cold running water to remove any dirt from their skins. Because the skins will be used later to hold the filling, it is important to clean them well. After washing, dry the potatoes carefully with a clean kitchen towel.
Place the whole potatoes directly on the oven rack or arrange them in a baking dish. Baking them whole allows the inside to become soft and fluffy while the skins develop a slightly crisp texture. Let the potatoes bake for about 35 to 40 minutes. To check if they are ready, insert a knife into the center of one potato; it should slide in easily without resistance.
Prepare the Mushroom Filling
While the potatoes are baking in the oven, begin preparing the filling. Peel the onion and finely chop it into small pieces so it cooks evenly and blends well with the mushrooms. Next, clean the button mushrooms and cut them into small pieces.
Place a skillet over medium heat and add the butter together with the olive oil. Once the butter has melted, add the chopped onion to the pan. Cook it gently while stirring occasionally until it becomes soft and translucent.
Add the chopped mushrooms to the skillet and continue cooking for several minutes. Stir occasionally so the mushrooms cook evenly. As they heat, they will release their natural moisture. Continue cooking until this moisture evaporates and the mushrooms begin to turn lightly golden, which enhances their flavor.
Add the Tomato
Dice the tomato into small cubes. If using cherry tomatoes, simply cut them into small pieces. Add the diced tomato to the mushroom mixture in the skillet.
Allow the mixture to simmer for about 3 to 4 minutes so the tomato softens and blends with the mushrooms and onions. This step adds a slight freshness and balance to the filling. Season the mixture with salt and black pepper according to your taste.
Hollow Out the Potatoes
Once the potatoes are fully baked, remove them from the oven and allow them to cool for a few minutes so they are easier to handle. Using a sharp knife, slice each potato in half lengthwise.
With a spoon, carefully scoop out the soft potato flesh from the center of each half. Be gentle and leave a thin layer of potato attached to the skin so the shells remain sturdy enough to hold the filling. Place all the scooped-out potato flesh into a mixing bowl.
Prepare the Filling Mixture
Using a fork or potato masher, mash the warm potato flesh in the bowl. Add the heavy cream and continue mashing until the mixture becomes smooth and creamy.
Next, add the prepared mushroom and onion mixture into the mashed potatoes. Sprinkle in half of the grated cheese and mix everything together thoroughly. The result should be a rich, creamy filling with evenly distributed mushrooms and melted cheese.
Fill and Bake Again
Spoon the filling generously back into each potato shell, slightly mounding it on top so each portion looks full and generous.
Sprinkle the remaining grated cheese evenly over the stuffed potatoes. Return them to the oven and bake for an additional 10 to 12 minutes. During this time, the cheese will melt and form a lightly golden topping.
Finish and Serve
Remove the stuffed potatoes from the oven once the cheese has melted completely and the tops look lightly golden. Finely chop the fresh parsley and sprinkle it over the hot potatoes just before serving.
Serve immediately while they are warm and the cheese is still melted.
Practical Tip
The potatoes can be baked ahead of time and stored in the refrigerator. When ready to serve, simply prepare the filling, stuff the potatoes, and bake them again until heated through and the cheese is melted.
Cooking Tip
For extra crispy potato skins, lightly brush the outside of the potatoes with olive oil before placing them in the oven for the first bake. This small step helps create a slightly crisp and flavorful outer layer
