Light Summer Luncheon Menu for 20: A Country Buffet

A summer luncheon in the country should feel easy for the guests and for whoever is cooking it. This menu was built for a hot July day, when nobody wants a heavy plate and the oven should be off by the time people arrive. Almost everything is served cold or at room temperature, most of it can be made the day before, and the only thing that needs a knife at the last minute is the bread. It feeds 20 at a buffet, with enough left for the cook's supper.
The menu
To start
- Watermelon gazpacho, served in small glasses
From the buffet
- Summer chicken rolled with a basil ricotta filling, sliced, with artichoke mayonnaise on the side
- Asian chicken salad with cashews on the side
- Mixed greens with seasonal fruit and blueberry vinaigrette
- Cherry tomato and mini mozzarella salad with basil vinaigrette
- Moroccan grain salad
- French bread and sweet butter
Dessert
- Lemon cake with lemon curd filling and lemon buttercream, with fresh blueberries
Why it works
The menu has two chicken dishes, which sounds like a mistake until you see them side by side. One is a cool, sliced roulade with a creamy herb center and a rich sauce; the other is a crunchy, tangy salad with sesame and ginger. They taste nothing alike, and between them they cover the guests who want a proper lunch and the ones who will make a plate of salads. The four salads move from leafy to juicy to hearty, so a plate built from them feels like a meal even without the chicken. The grain salad is the one vegetarians and anyone avoiding meat will lean on, so make plenty.
The colors help too: pink soup, green and white chicken, red tomatoes, blueberries scattered on the greens and again on the cake. A buffet that looks like summer gets eaten.
Quantities for 20
| Dish | Quantity | Per guest |
|---|---|---|
| Watermelon gazpacho | about 3 quarts | 4 oz glass |
| Chicken roulade | 6 lb boneless breasts, 4 rolls | about 4 oz cooked |
| Artichoke mayonnaise | about 2 cups | 1 1/2 tbsp |
| Asian chicken salad | 3 lb cooked chicken, plus cabbage and vegetables | 1 cup |
| Cashews for the side | 1 1/2 cups | |
| Mixed greens | 1 1/2 lb greens, 3 cups fruit | 1 1/2 cups loose |
| Blueberry vinaigrette | 1 1/2 cups | |
| Cherry tomato and mozzarella | 3 pints tomatoes, 1 1/2 lb mini mozzarella | 1/2 cup |
| Moroccan grain salad | 1 1/2 lb dry couscous or bulgur, cooked | 3/4 cup |
| French bread | 4 baguettes | 2 to 3 slices |
| Butter | 1 lb | |
| Lemon cake | one 10 inch layer cake, or two 8 inch | 1 slice |
Because there are two chicken dishes, you need less of each than if either stood alone. That is why the roulade is planned at about 4 ounces a person and not the 6 I would plan for a single main.
The prep timeline
Two days before
Make the lemon curd and refrigerate it. Bake the cake layers, cool, wrap and refrigerate or freeze. Make the blueberry vinaigrette and the basil vinaigrette.
The day before, morning
Make the gazpacho; it improves overnight. Mix the basil ricotta filling, roll it into the pounded chicken breasts, tie or wrap them, and roast at 375°F (190°C) until the center reads 165°F (74°C), about 35 to 45 minutes depending on thickness. Cool and refrigerate whole; they slice far more cleanly cold.
The day before, afternoon
Poach the chicken for the Asian salad and shred it. Make the dressing. Make the grain salad without the herbs. Stir together the artichoke mayonnaise. Fill and frost the cake, and refrigerate it.
The morning of
Halve the tomatoes and toss them with the mozzarella. Wash and dry the greens and prepare the fruit (peaches, strawberries or melon, depending on the week). Toss the Asian salad with its vegetables and dressing, leaving the cashews in a bowl beside it so they stay crisp and so guests with nut allergies can skip them.
One hour before
Slice the roulade on a slight angle, about 1/2 inch thick, and fan it on a platter. Add the herbs to the grain salad. Dress the tomato salad. Chill the gazpacho glasses.
At serving time
Dress the greens. Slice the bread. Scatter blueberries over the cake.
Buffet layout
For 20 guests, one table about 8 feet long is enough, with the gazpacho on a small separate table or tray near the door so guests take a glass as they come in. On the main table, run left to right: plates, mixed greens, tomato and mozzarella, grain salad, Asian chicken salad with the cashews, the sliced roulade with the artichoke mayonnaise beside it, then bread and butter, then napkins and forks. Dressed salads first means people take smaller portions of the chicken at the end of the line, which keeps it from running out.
Cold food on a summer porch needs watching. Set the chicken platters and the mayonnaise in larger trays of ice, or bring them out in two rounds and keep the second round in the refrigerator at 40°F (4°C) or below. Nothing creamy should sit out longer than 2 hours, or 1 hour if it is over 90°F (32°C). If you are having the main dishes made by a kitchen and dropped off, the food-only catering guide covers the setup.
The cake goes out after lunch, on its own small table, with the coffee and a pitcher of iced tea.
Swaps for dietary needs
- Vegetarian. Double the grain salad and add chickpeas to it. A roulade of grilled eggplant around the same basil ricotta filling makes a vegetarian main.
- Nut allergies. The cashews are already on the side. Check the grain salad if you like to add almonds or pistachios.
- Gluten-free. Use quinoa in the grain salad and serve the Asian chicken salad with a tamari-based dressing.
- Dairy-free. The gazpacho, the Asian salad, the greens and the grain salad are dairy-free as written.
For another fruit-and-greens salad that works on a buffet, the winter greens with pears and cashews uses the same idea in a colder month.
The gazpacho
This is the dish people ask about. It is sweet, sharp and cold, and it can be made a full day ahead.

Notes from the kitchen

- For a smoother soup, press it through a coarse sieve after blending.
