Like many home cooks, I often make extra rice, leaving plenty in the pan after meals. Tossing it out? Not on my watch. After years of experimenting with leftovers, I've perfected this simple rice gratin—a delicious, budget-friendly way to transform scraps into a hearty dish.
It's made entirely from pantry staples and fridge odds-and-ends, proving you can eat well without waste or extra spending. Here's the straightforward recipe:

- Leftover rice
- Ham or leftover meat
- Vegetable scraps (ratatouille, tomatoes, zucchini, mushrooms...)
- Gruyère
1. Mix all the ingredients together.
2. Transfer to a gratin dish.
3. Add fresh cream or béchamel sauce.
4. Top with Gruyère.
5. Bake at 180°C for 15 min.
Your leftover rice is now a golden, cheesy gratin—easy, quick, and economical!
This anti-waste recipe is simple, original, and ready in minutes. It's a complete meal perfect for summer or winter, keeping your family satisfied year-round.
Ideal for budget-conscious families or students seeking meals under €1. Pair with a fresh salad for a full spread.
Adapt for excess pasta, veggies, or potatoes too—eat well without overspending.
