Description
A warm, comforting potato bake with caramelized onion soup mix and melted cheese that creates crispy golden edges. Ready in 45 minutes, this dish is perfect as a hearty side or a main meal.
Ingredients
Scale
- 3 pounds Russet potatoes (~1.4 kg)
- 1 packet caramelized onion soup mix (about 1.4 oz / 40g)
- 2 cups shredded sharp cheddar cheese (200g)
- ½ cup grated Parmesan cheese (50g)
- 1 cup sour cream (240ml)
- 4 tablespoons unsalted butter (56g)
- 1 cup milk (whole or 2%) (240ml)
- 1 teaspoon fresh thyme, chopped (optional)
- Salt and black pepper to taste
Instructions
- Wash and peel the potatoes. Slice them into thin rounds about 1/8 inch thick (3 mm).
- In a large mixing bowl, combine the caramelized onion soup mix, sour cream, milk, melted butter, chopped thyme, and a few grinds of black pepper. Stir until smooth.
- Add the sliced potatoes to the bowl with the sauce and gently toss to coat every slice.
- Pour half of the potato-sauce mixture into a 9×13 inch baking dish. Sprinkle half the shredded cheddar and Parmesan evenly over the top.
- Layer the rest of the potatoes and sauce, finishing with the remaining cheese.
- Cover the dish tightly with aluminum foil and bake in a preheated 375°F (190°C) oven for 25 minutes.
- Remove the foil and bake uncovered for another 5 to 7 minutes until the cheese edges bubble and turn golden brown.
- Let the bake rest for 5 minutes before serving.
Notes
Use a mandoline slicer for even potato slices. Cover with foil while baking to keep moisture in, then uncover to crisp cheese edges. Fresh grated cheese melts and crisps better than pre-shredded. Butter helps with browning. Optional: add cooked bacon or sautéed mushrooms for variation. To get extra crispy edges, broil for 1-2 minutes at the end, watching carefully.
