A layered root vegetable gratin is a rich, baked dish of thinly sliced root vegetables cooked in cream and topped with golden cheese. It’s creamy in the middle, crispy on top, and deeply comforting.
🥔🥕 Layered Root Vegetable Gratin
🧂 Ingredients
Vegetables (mix & match):
- 2 medium potatoes (thinly sliced)
- 2 carrots (thinly sliced)
- 1 sweet potato (optional, for sweetness)
- 1 small beetroot (optional, for color and earthiness)
- 1 onion (thinly sliced, optional)
Cream sauce:
- 2 cups heavy cream (or cooking cream)
- 1 cup milk
- 2–3 cloves garlic (minced)
- 1 tsp salt
- 1 tsp black pepper
- 1 tsp thyme or rosemary (dried or fresh)
- Pinch of nutmeg (optional but classic)
Cheese topping:
- 1½ cups grated cheese (cheddar, mozzarella, or Gruyère)
- 2 tbsp butter (for dotting on top)
👨🍳 Instructions
1. Prep vegetables
- Peel and slice all vegetables very thin (use a knife or slicer)
- Keep slices even so they cook uniformly
2. Make cream mixture
- In a bowl, mix cream, milk, garlic, salt, pepper, herbs, and nutmeg
- Stir well so flavors combine
3. Layer the gratin
In a buttered baking dish:
- Layer sliced vegetables (alternate colors for a nice look)
- Pour a little cream mixture
- Repeat layers until everything is used
👉 Make sure cream covers at least ¾ of the vegetables
4. Add topping
- Sprinkle cheese evenly on top
- Dot with small pieces of butter for extra browning
5. Bake
- Preheat oven to 180°C
- Cover with foil and bake for 40 minutes
- Remove foil and bake another 20–25 minutes until golden and bubbling
6. Rest before serving
- Let it sit for 10–15 minutes so it sets
- This helps it slice cleanly
🍽️ Serve with:
- 🍗 Roast chicken or grilled meat
- 🥩 Steak or meatballs
- 🥗 Simple green salad
- 🥖 Crusty bread
🌟 Tips
- Slice vegetables thin so they cook evenly
- Don’t skip resting time—it helps structure
- Gruyère or cheddar gives the best cheesy crust
- Add extra garlic if you like stronger flavor
