Decide the Type of Event

Before diving into menu planning, it’s important to think about the type of event you’re hosting. Casual vs. Formal: For a relaxed, informal event like a backyard BBQ  or a casual get-together, you might opt for buffet-style service with easy-to-eat finger foods or platters. However, for a more formal gathering, like a sit-down dinner or a special celebration, you’ll likely want to go for a more structured menu with plated courses.

  • Indoor vs. Outdoor: Hosting an outdoor event? Consider foods that are easier to transport and serve outside, such as grilled meats, salads, and chilled drinks. For an indoor setting, you have more flexibility with the type of dishes, as heating and serving will be easier to manage.
  • Theme and Occasion: Is your event themed? Whether it’s a birthday party, anniversary, or holiday celebration, the theme can guide your food choices. A themed event can be a great opportunity to create a menu that aligns with the occasion. 

By considering the type of event early on, you’ll have a clear direction for your catering, making everything else—menu planning, portions, and serving—fall into place smoothly.

Dietary Considerations

It’s important to account for dietary preferences or restrictions among your guests. Whether it’s catering for vegetarians, vegans, or those with food allergies, make sure your menu includes options that suit everyone. Communicate with guests beforehand to confirm any restrictions. This will allow you to balance your menu by providing satisfying choices for all diets, ensuring that no guest feels left out.

For dairy-free guests, use alternatives like almond milk in creamy dishes, and for those with nut allergies, ensure nut-free options and prevent cross-contamination.

Budgeting for Your Event: 7 Practical Tips

When catering for a group of 20 guests, you can focus on making smart choices that maximise quality without overspending. Here are some practical tips:

  • Set a clear budget: Breaking down your overall budget per guest will help you get a clearer idea of the costs for food, drinks, and service.
  • Leverage bulk buying: Even for a smaller group, bulk purchases of items like drinks or non-perishables can lead to savings.
  • Keep the menu simple: A well-curated menu with fewer but higher-quality dishes can help you cut down on costs without sacrificing the experience. Focus on dishes that are both easy to prepare in bulk and sure to impress. 
  • Use seasonal ingredients: Using seasonal ingredients can help reduce costs, as they are typically more affordable and readily available. 
  • Opt for a buffet service: A buffet is often more cost-effective because it allows you to prepare food in larger batches. With fewer serving staff required and a more flexible setup, buffets are ideal.
  • Plan for additional costs: For a group of 20, there are bound to be some additional expenses like tables, chairs, crockery, service staff, etc. Calculate these in your budget to avoid any last-minute surprises.
  • Request tailored and multiple quotes: If you are hiring a private chef or caterer, ask them to tailor their packages to a group of 20. Reach out to different caterers to get quotes so that you can compare and choose the best ones.

Creating a Timeline for the Day: 7 Essential Steps

Carefully planning how to cater for 20 people ensures everything runs smoothly and food is served on time. Here’s how to create an effective timeline for your event:

  • One week before: Finalise the guest list and menu. Ensure all necessary kitchen equipment, tableware, and serving tools are ready. If you plan to hire staff, confirm their availability and roles.
  • Five days before: Double-check your ingredient orders and purchase any remaining items. Set up a rough layout of the dining area and serving stations to ensure everything fits smoothly.
  • Two days before: Prepare non-perishable elements like desserts and baked goods. Store them properly to maintain freshness.
  • One day before: Marinate meats and complete any pre-cooking tasks like making stocks or preparing casseroles. Set up tables, chairs, and any decorations needed for the event.
  • Morning of the event: Begin cooking all the main dishes. Keep all perishable items refrigerated until it’s time to serve.
  • Two hours before: Reheat pre-cooked dishes, finalise main dishes and set up the buffet or serving stations. Begin preparing drinks and setting up the bar area if necessary.
  • 30 minutes before: Add final garnishes, arrange food on warming trays or serving platters and ensure everything is at the correct temperature. Double-check that all drinks are ready to serve
