- Set your oven to 200°C (400°F) and allow it to heat up fully before baking. 
- Rinse the potato under running water to remove any dirt, and dry it thoroughly with a clean kitchen towel. Pierce the skin of the potato several times with a fork to prevent it from bursting during baking. 
- Place the prepared potato directly onto the middle oven rack or on a baking tray lined with parchment paper. Bake for 45 to 60 minutes, checking occasionally by inserting a knife or skewer to ensure the interior is soft and fully cooked. 
- Empty the canned baked beans into a small saucepan. Warm them over medium heat, stirring occasionally to prevent sticking. Let them gently simmer until they are evenly heated through. 
- Once the potato is out of the oven, place it on a serving plate. Use a knife to make a deep cut down the center and carefully press the ends together to slightly open it up. Add a dollop of butter, if desired, and season with a pinch of salt and a sprinkle of freshly ground black pepper. 
- Spoon the hot baked beans over the potato, ensuring the sauce seeps into the fluffy potato flesh. 
- For an added layer of flavor, sprinkle shredded cheese on top, scatter chopped green onions, or add a dollop of creamy sour cream. 
- Enjoy the baked potato while it’s still warm, paired with your favorite side dish or on its own for a simple and satisfying meal.
