Step-by-Step Instructions
Step 1: Prep the Potatoes
Preheat oven to 400°F (200°C).
In your casserole dish, toss potatoes with olive oil, salt, and pepper.
Arrange somewhat flat for even cooking.
Step 2: Make the Cream Sauce
In a bowl, whisk together:
- Heavy cream
- Milk
- Garlic
- Sautéed onions
- Parmesan
- Parsley
- Thyme
- Nutmeg
Mix until fully combined.
Step 3: Pour Over
Slowly pour mixture over potatoes.
Use spoon to distribute garlic and onion evenly
Ensure most potatoes are lightly submerged.
Step 4: Bake Covered
Cover tightly with foil.
Bake for 30 minutes
This steams and softens potatoes.
Step 5: Golden Finish
Remove foil.
Sprinkle shredded Gruyère or cheddar evenly on top.
Bake uncovered 20–25 minutes, until:
- Top is golden
