Easy Tartiflette Recipe — Potatoes, onions and melting cheese are baked together for a simple, rich casserole suited to winter meals and casual gatherings.

Coquilles de Moules Gratinées Style Saint Jacques — Mussels are presented in individual shells with a creamy filling and golden topping inspired by traditional coquilles Saint-Jacques.
Tips for Choosing the Right Gratin or Casserole Recipe
Choose a potato or vegetable gratin when you need a rich side dish for roast beef, chicken, pork or a holiday menu. Chicken, beef and pasta casseroles are more suitable as complete family dinners, especially when you want to prepare everything in one baking dish. Tartiflette is ideal for a cold-weather gathering, while the gratinéed mussels offer a more refined option for entertaining or serving as a starter.
Easy Substitutions
Different waxy or all-purpose potatoes can be used in most gratins, although very floury potatoes may break down more during baking. Broccoli can often replace cauliflower, and yellow squash can stand in for zucchini. Gruyère, Emmental, cheddar, mozzarella and other good melting cheeses can be adjusted according to the recipe and the flavour you prefer. Ground turkey can replace beef in some casseroles, while different short pasta shapes can be used in pasta bakes as long as their cooking time is adjusted.
Storage and Make-Ahead Tips
Many gratins and casseroles can be assembled several hours ahead, refrigerated and baked closer to serving time, though a cold dish may require additional oven time. Potato gratins, tartiflettes and pasta bakes generally reheat well in a covered baking dish before being uncovered briefly to refresh the browned top. Vegetable gratins may release some moisture after refrigeration, and seafood gratins are best prepared and served with less delay. Refrigerate leftovers promptly and follow the storage guidance provided with each individual recipe.

FAQ
What is the difference between a gratin and a casserole?
A gratin is usually baked in a shallow dish and finished with a browned crust made from cheese, breadcrumbs, cream or a combination of toppings. Casserole is a broader term for a complete dish baked and often served in the same container.
What potatoes are best for gratin dauphinois?
Waxy or medium-starch potatoes hold their shape while absorbing the cream during baking. Yukon Gold and similar all-purpose potatoes are reliable choices because they become tender without immediately falling apart.
Can gratin recipes be assembled ahead of time?
Many can be assembled ahead and refrigerated before baking. Potato slices may darken if left exposed, so keep them fully covered by the sauce and follow the instructions in the individual recipe.
How do I get a golden crust on a gratin?
Use a wide baking dish so more of the surface is exposed, and add cheese or breadcrumbs when the recipe calls for them. If the centre is fully cooked but the top remains pale, a brief period under the broiler can deepen the colour, but it should be watched closely.
Can I freeze cheesy casseroles?
Many meat and pasta casseroles can be frozen, although cream sauces and vegetables may change slightly in texture after thawing. Potato gratins can sometimes become watery or grainy, so freezing recommendations should be checked for the specific recipe.
Which gratin recipes work best as side dishes?
Traditional Gratin Dauphinois, the three-cheese potato gratin, zucchini gratin, cauliflower gratin and potato-carrot gratin are the strongest side-dish options. The chicken, beef, pasta and tartiflette recipes are substantial enough to serve as main courses.
