Ingredients
Scale
Potatoes
- 4 medium russet potatoes
Garlic Butter Mixture
- 3 tablespoons unsalted butter, melted
- 3 tablespoons olive oil
- 4 cloves garlic, minced
- 1/2 teaspoon salt
- 1/4 teaspoon black pepper
- 1/2 teaspoon dried thyme (or fresh, chopped)
Topping & Garnish
- 1/4 cup grated Parmesan cheese
- Fresh parsley, chopped (for garnish)
Instructions
- Preheat the oven: Set your oven to 400°F (200°C) to ensure it reaches the right temperature while you prepare the potatoes.
- Prepare the potatoes: Wash and dry the russet potatoes thoroughly. Make thin, even slices crosswise along each potato, spacing about 1/8 to 1/4 inch apart. Be careful to stop slicing about 1/4 inch before reaching the bottom so the potato remains intact.
- Arrange on baking sheet: Place the sliced potatoes upright on a parchment-lined baking sheet, spreading the slices slightly to expose the cuts for better crisping and seasoning penetration.
- Make garlic butter sauce: In a small bowl, mix the melted butter, olive oil, minced garlic, salt, black pepper, and thyme until well combined.
- Brush potatoes with the mixture: Generously brush the garlic butter sauce over and between the slices of each potato, ensuring good coverage to maximize flavor.
- Roast the potatoes: Roast in the preheated oven for 40 to 45 minutes. Halfway through the cooking time, baste the potatoes again with the remaining garlic butter mixture to keep them moist and flavorful.
- Add Parmesan cheese: Remove the potatoes from the oven and sprinkle the grated Parmesan cheese over the top. Return the potatoes to the oven for an additional 5 minutes to let the cheese melt and develop a golden crust.
- Garnish and serve: Once out of the oven, sprinkle chopped fresh parsley over the potatoes for a bright, fresh finish. Serve warm as a delicious side dish.
Notes
- Use a sharp knife to make clean, even cuts for the best cooking results.
- Russet potatoes work best because they become crispy outside and fluffy inside when roasted.
- For more flavor, you can add a pinch of smoked paprika or grated Parmesan inside some of the slices before baking.
- If fresh thyme is available, use it instead of dried for a fresher flavor.
- Make sure to baste halfway through cooking to keep potatoes tender and infused with garlic butter.
