Squash

Make this luscious dessert a day ahead.

A creamy white cheddar cheese sauce makes this gratin luxurious enough to serve as a vegetarian main course.

Make or buy a favorite pumpkin pie for dessert. What to drink: A fruit-forward Zinfandel or Malbec.

An elegant starter or side.

Using frozen winter squash purée makes putting together this soup extremely speedy; then just let it simmer while the turkey roasts. The lime juice may seem like an unusual Thanksgiving ingredient, but its tart flavor gives a lift to the sweetness of the squash and tempers the spicy toasted pumpkin seeds. The seeds themselves are addictive, so if you think you might want to have extra around for noshing, consider doubling that recipe. They will keep for at least a week or two in an airtight container—if they last that long!

Watch out, pumpkin pie! This dessert is delicious even without a caloric crust. It's a light and flavorful soufflé consisting mostly of egg whites, a great source of high-quality protein. To further up the health quotient, naturally rich but low-calorie unsweetened soy milk is used in place of whole milk.

A bite of this flan, fragrant with traditional pumpkin-pie spices, is very comforting despite the dessert's modern looks; a topping of pumpkin seeds, seasoned with cayenne, creates a play of sweet and heat.

When the pumpkin pie is gone, but you've only just begun to get your fill of pumpkin desserts, this bundt will fill the void quite nicely (and the somewhat more assertive spices will welcome the season ahead). Best of all, the flavors continue to develop and the cake tastes even better a few days after it's baked, so it's perfect to have on hand at this time of year, when guests tend to drop in unexpectedly.

The flavor combinations in this creamy yet light soup are complex, but making it is very easy. Like the best appetizers, the soup wakes up the palate and is not too filling.

An inventive new take on a classic fall side. What to drink: A fruity red with a nice acidity. Try: Keenan 2002 Merlot, Carneros, Napa ($25).

Ultra-creamy Fontina cheese and a layer of black-olive tapenade give this an unctuous, satisfying quality that is usually missing from other veggie pizzas. What to drink: Dry rosé or a spicy Rhône-style red.
