Ingredients for Layered Root Vegetable Gratin
Main Ingredients
- 2 medium potatoes, thinly sliced
- 2 medium carrots, thinly sliced
- 1 medium sweet potato, thinly sliced
- 1 parsnip, thinly sliced
- 1 cup heavy cream
- 1 cup milk
- 2 cloves garlic, minced
- 1 teaspoon salt
- 1 half teaspoon black pepper
- 1 teaspoon dried thyme or rosemary

- 1 half cup grated Parmesan cheese
Optional Ingredients
- 1 tablespoon butter for greasing

- 1 small onion, thinly sliced
- A pinch of nutmeg for extra warmth
How to Make Layered Root Vegetable Gratin
Step 1: Prepare the Oven and Dish
Preheat your oven to 180 degrees Celsius or 350 degrees Fahrenheit. Grease a baking dish with butter or olive oil to prevent sticking.
Step 2: Slice the Vegetables
Wash and peel all root vegetables. Slice them into thin, even rounds. Thin slices help the vegetables cook evenly and become soft during baking.
Step 3: Prepare the Cream Mixture
In a bowl, mix cream, milk, minced garlic, salt, black pepper, thyme, and a pinch of nutmeg. Stir well so the flavors combine evenly.
Step 4: Start Layering
Place a layer of potatoes at the bottom of the dish. Then add carrots, sweet potatoes, and parsnips. Repeat the layers until all vegetables are used.
Step 5: Add Cream Mixture
Slowly pour the cream mixture over the layered vegetables. Make sure it spreads evenly and reaches all corners of the dish.
Step 6: Add Cheese
Sprinkle cheddar cheese and Parmesan cheese on top. This will create a golden and crispy top layer when baked.
Step 7: Cover and Bake
Cover the dish with foil and bake for 40 minutes. This helps the vegetables soften without drying out.
Step 8: Uncover and Finish Baking
Remove the foil and bake for another 15 to 25 minutes until the top is golden brown and bubbling.
Step 9: Rest and Serve
Let the gratin rest for 10 minutes before serving. This helps it set and makes it easier to cut into neat portions.
Notes
- Slice vegetables evenly so they cook at the same speed.
- Do not skip the resting time after baking. It helps the layers set properly.
- You can use only potatoes if you prefer a simpler version.
- Add more cheese for a richer and creamier taste.
- Use fresh garlic for stronger flavor.
- Covering with foil first prevents burning and ensures soft vegetables.
- You can add more herbs like rosemary, thyme, or oregano.
- A mandoline slicer can help create thin and even slices.
- Do not add too much liquid or the gratin may become watery.
- Leftovers taste even better the next day.
