Tips for Successful Make-Ahead Christmas Sides

Choose Dishes That Improve Over Time

Some dishes — like casseroles, roasted vegetables, and layered potatoes — become even more flavorful after resting.

Prep, Don’t Fully Cook

Many sides do best when assembled in advance but baked or warmed just before serving.

Use Airtight Containers

This keeps flavors fresh and prevents vegetables from becoming soggy.

Reheat Correctly

Use low and slow heat to bring dishes back to life without drying them out.

Label Everything

Include dates, ingredients, and reheating instructions for maximum organization.
