Enter your guest count, pick one or more soup types, and choose whether you are serving soup as a starter, a main dish, or as one item on a buffet.

Soup Types

Chili

A thick, protein-rich soup built on beans, beef, tomatoes, and chili spices. Hearty enough to work as a main dish on its own.

Suggested toppings: shredded cheddar, sour cream, diced onion, cornbread.

French Onion

A rich beef broth base with deeply caramelized onions, traditionally topped with toasted bread and melted cheese.

Suggested toppings: gruyere cheese, toasted baguette slices.

Minestrone

An Italian vegetable soup with beans and small pasta in a tomato-forward broth. Light enough for a starter, filling enough for a bowl on its own.

Suggested toppings: grated parmesan, crusty Italian bread.

Potato

A creamy, starchy soup that eats like a meal. Loaded baked potato style toppings turn it into a main dish or buffet centerpiece.

Suggested toppings: bacon bits, chives, shredded cheddar, sour cream.

Tomato

A smooth, tangy tomato base that works well as a starter or paired with a sandwich for a light meal.

Suggested toppings: grilled cheese croutons, fresh basil, parmesan.

Butternut Squash

A silky, mildly sweet squash puree. Rich enough to satisfy as a main course, especially in cooler months.

Suggested toppings: toasted pepitas, a swirl of cream, sage.

Frequently Asked Questions

How much soup do I need per person?

For a starter, plan on about 1 cup per person. For a main dish, plan on 1.5 to 2 cups per person, depending on how hearty the soup is. For a buffet where soup is one of several dishes, plan on 1 to 1.5 cups per person.

Should I make more soup for a main dish versus a starter?

Yes. A starter portion is roughly 1 cup, while a main dish portion is typically 1.5 to 2 cups per person. Heartier soups like chili, potato, and butternut squash lean toward the higher end when served as the main course.

How far in advance can I make soup for a party?

Most soups can be made 1 to 3 days ahead and stored in the refrigerator. Many soups (chili, minestrone, tomato, butternut squash) actually taste better the next day as the flavors develop. Reheat gently on the stovetop and thin with broth or water if needed.

Can I mix multiple soup types for a soup bar?

Yes, offering 2 or 3 soup options is common for a soup bar. Guests will usually split roughly evenly across the choices, so divide your total guest count by the number of soups you plan to serve and calculate each one for that share of the crowd.
