Tips for Hosting and Prepping in 2025

• Scale smartly: Multiply ingredient quantities as needed for your guest count — many casseroles easily scale to feed 12-16.
• Make ahead: Assemble dishes the day before where possible; refrigerate and bake before dinner.
• Freeze for backup: Some casseroles (like mashed potato or stuffing varieties) freeze well and can be pulled out and baked. Southern Living+1
• Mix and match mains & sides: Choose a couple casseroles as mains and others as sides to give variety.
• Leftover friendly: Many of these dishes convert to lunches the next day (lasagna slices, sweet potato casserole reheated).
• Keep it balanced: Offer at least one lighter veggie dish among the heavier options (e.g., broccoli & wild rice).
• Consider dietary needs: Provide a vegetarian or meat-free casserole so guests with different diets feel included.
• Use festive presentation: Bring casseroles in their baking dish right to the table for that comforting “just out of the oven” vibe.
