Ingredients
Scale
- 4 large russet potatoes
- 2 tablespoons olive oil
- Salt and black pepper, to taste
- 2 large onions, thinly sliced
- 2 tablespoons butter
- 1 teaspoon sugar
- 1 teaspoon balsamic vinegar
- 1/2 cup beef broth
- 1 cup Gruyère cheese, shredded
- Fresh thyme, for garnish
Instructions
- Prep and Bake Potatoes: Preheat your oven to 400°F (200°C). Fork-pierce the potatoes, then rub them with olive oil and a sprinkle of salt. Bake on a sheet until tender, about 60 minutes.
- Caramelize Onions: While potatoes bake, melt butter in a skillet. Add onions, sugar, and salt, cooking until golden and soft, about 25 minutes. Pour in balsamic vinegar and beef broth, simmering until absorbed.
- Prepare Potato Shells: Once baked, halve potatoes lengthwise and scoop out the centers, leaving a shell.
- Mix Filling: Combine the scooped potato with the onion mixture and half the Gruyère. Spoon this back into the shells.
- Bake Again: Top stuffed potatoes with the remaining cheese. Bake for 15 minutes, or until the cheese bubbles and browns.
- Garnish and Serve: Sprinkle with fresh thyme. Serve hot for a melt-in-your-mouth experience.
- Prep Time: 15 minutes
