Holiday meals bring generations together, yet each group carries its own sense of what a “true” classic tastes like. Boomers grew up with certain dishes appearing on the table year after year, so those flavors still feel like home. Gen Z didn’t inherit the same attachments and often leans toward fresher ideas instead. Keep reading to see which long-time favorites remain firmly in place.
Green Bean Casserole With Canned Soup

Just imagine a 1950s kitchen where a casserole called “Green Bean Bake” saved families’ time by combining canned green beans with condensed mushroom soup. Boomers grew up seeing it at every holiday, so it still feels comforting to them. Younger diners prefer fresher flavors, so the canned base feels heavy and out of place today.
Jell-O Salad With Fruit And Marshmallows

Back then, a bright gelatin mold packed with fruit felt creative and modern, which helped it earn a regular spot on Boomer holiday tables. Today, Gen Z approaches the same dish with a different lens, noticing the artificial flavor and firmer texture, and the once-celebrated favorite settles into a much gentler presence.
Ambrosia Salad

Younger diners hesitate when they see pineapple, oranges, coconut, and marshmallows coated in sour cream, as the mix feels puzzling to modern tastes. Olders remember it as a sweet, celebratory salad that brightened the table. The bowl often lingers between both reactions, which holds memories for some and gentle confusion for others.
Canned Cranberry Sauce

Watch how the canned cranberry sauce behaves on the table: it slides out shaped like the can, stands firm, and slices neatly. Boomers reach for it immediately because that tidy form matches what they remember. Gen Z pauses, expecting real fruit and brighter flavor, and usually moves past the smooth jelly altogether.
Oyster Stuffing

Oysters add a salty depth to this stuffing, a flavor that comes from old coastal cooking and still feels familiar to many Boomers. Younger diners rarely see seafood mixed with bread and herbs, so the combination seems unusual to them, and the dish often gets its strongest support from those raised with it.
Giblet Gravy

Boomers meet giblet gravy with memories of kitchens where every turkey part added flavor, so organ pieces in the sauce feel normal to them. Gen Z approaches it through modern expectations, where organ meat rarely appears in everyday meals. Those two mental frameworks meet in one bowl, creating an instant divide.
Sweet Potatoes With Marshmallow Topping

Sweet potatoes topped with melted marshmallows make a very sweet side dish that Boomers remember seeing at nearly every holiday meal. Early promotions helped the topping become a tradition. The newer generation expects vegetables to taste less sugary, so the candy-like layer feels unusual, and the dish usually appeals most to those raised with it.
Celery Stuffed With Pimento Cheese

Boomers see crisp celery filled with pimento cheese—a creamy, pepper-studded spread once common on relish trays—and recall simple starters shared before big meals. Younger diners expect fresher appetizers and step back from the bold flavor. The tray moves around the room, carrying two different ideas of what a good appetizer looks like.
Congealed Salad (Savory Gelatin Mold)

This salad uses savory gelatin to hold vegetables, olives, or tuna in a firm, molded shape that once felt stylish on mid-century holiday tables. The older generation remembers it as a festive centerpiece. Gen Z notices the wobble and unusual texture, so it often stays on display rather than being served.
Pearled Onions In Cream Sauce

Small onions cooked in cream turn into a soft, rich side dish that pairs well with traditional holiday meals that favor warm, comforting dishes. Gen Z prefers lighter textures, so the creamy coating feels heavy to them. The bowl usually waits for those who enjoy richer flavors and skip over simpler vegetable sides.
