Casseroles make weeknight dinners simple. These 15 recipes each use just four ingredients. You can put them together fast with items you probably have. They work well for feeding a family or prepping ahead. Each one delivers good flavor without extra work.
Helpful Tips Before You Start
These quick pointers will help your 4-ingredient casseroles cook evenly and taste their best.
Choose the Right Pan Size
A too-large dish spreads the mixture thin and dries it out. An 8 by 8 or 9 by 13 works for most of these recipes.
Bring Dairy or Eggs to Room Temp
Cold ingredients can cause uneven baking in short recipes. Set them out while you preheat the oven.
Layer in the Right Order
Put denser items like potatoes or pasta on the bottom. This keeps everything from turning soggy.
Check at the Minimum Time
Ovens vary, so start testing five minutes early. The top should be golden and the center hot.
Rest the Casserole Five Minutes
This lets the layers firm up for cleaner slices when you serve.
