Greek Souvlaki for 50 People — Lemon, Garlic, and Tzatziki Ratios sounds like a lot of math, but it boils down to a few reliable formulas. Once you set the marinade and sauce ratios, you can scale up without losing flavor. I’ll give you proven amounts for chicken and pork, the right lemon-garlic balance, and a creamy, not-runny tzatziki that holds on a buffet. By the end, you’ll have a step-by-step plan, clear shopping lists, and timing that works.

The Core Ratios: Lemon, Garlic, and Oil

For souvlaki marinades, think in parts so you can scale easily. The sweet spot for bright but not harsh flavor: 2 parts lemon juice : 1 part olive oil : 1 part Greek yogurt (optional for chicken). Garlic should be present but not raw-tasting.

• Lemon: 2 tablespoons per pound of meat
• Olive oil: 1 tablespoon per pound
• Garlic: 1 large clove per pound (or 1 teaspoon minced)
• Oregano: 1 teaspoon dried per pound (or 1 tablespoon fresh)
• Salt: 3/4 teaspoon kosher salt per pound in marinade; finish with more after grilling
• Black pepper: 1/4 teaspoon per pound

For chicken, add 1 tablespoon Greek yogurt per pound to tenderize and help browning. For pork, skip yogurt; add 1 teaspoon red wine vinegar per pound if you like extra tang.

How Much Meat for 50 People

Portions for a crowd depend on sides. With pita, salad, and potatoes, plan 6–7 ounces cooked meat per person. That’s 8–9 ounces raw.

• Chicken thighs (best for juiciness): 28–30 pounds raw (yields ~20–22 pounds cooked)
• Pork shoulder or pork loin (shoulder is juicier): 28–30 pounds raw
• Skewers: 10–12-inch skewers hold ~5–6 ounces raw. Plan 1.5–2 skewers per person.

Feeding mixed diets? Do half chicken, half pork: ~15 pounds of each.

Scaled Marinade for 50 Servings

Chicken Souvlaki (15 lbs)

• Lemon juice: 30 tablespoons (about 1 3/4 cups; 12–14 lemons)
• Olive oil: 15 tablespoons (just under 1 cup)
• Greek yogurt: 15 tablespoons (just under 1 cup)
• Garlic: 15 large cloves, finely grated
• Dried oregano: 15 teaspoons (5 tablespoons)
• Kosher salt: 11–12 teaspoons (about 4 tablespoons)
• Black pepper: 4 teaspoons

Pork Souvlaki (15 lbs)

• Lemon juice: 30 tablespoons (about 1 3/4 cups)
• Olive oil: 15 tablespoons (just under 1 cup)
• Red wine vinegar: 15 teaspoons (5 tablespoons)
• Garlic: 15 large cloves, finely grated
• Dried oregano: 15 teaspoons (5 tablespoons)
• Kosher salt: 11–12 teaspoons (about 4 tablespoons)
• Black pepper: 4 teaspoons

Doing all one meat at ~30 lbs? Double the amounts above.

Tzatziki for 50: Thick, Scoopable, Not Watery

Tzatziki separates on a buffet if you don’t strain the dairy and cucumbers. Use this sturdy ratio per 10 people, then multiply by 5.

Base Ratio (serves ~10)

• Greek yogurt (10% or whole milk): 2 cups
• Grated cucumber: 1 heaping cup, squeezed dry
• Lemon juice: 2 tablespoons
• Olive oil: 1 tablespoon
• Garlic: 1 large clove, microplaned
• Dill: 2 tablespoons fresh, minced (or 2 teaspoons dried)
• Salt: 1 teaspoon kosher
• Black pepper: 1/4 teaspoon

Scaled for 50

• Greek yogurt: 10 cups (about 2.5 quarts)
• Grated cucumber: 5 heaping cups, squeezed very dry
• Lemon juice: 10 tablespoons (just over 1/2 cup)
• Olive oil: 5 tablespoons
• Garlic: 5 large cloves
• Dill: 10 tablespoons fresh, minced
• Salt: 5 teaspoons kosher (adjust to taste after chilling)
• Black pepper: 1 1/4 teaspoons

Key step: Salt the grated cucumber lightly, let sit 10 minutes, then squeeze hard in a towel until nearly dry. If your yogurt isn’t very thick, strain it in cheesecloth for 30–60 minutes.

Step-by-Step: Prep Timeline and Workflow

48–24 Hours Before

1. Cut meat into 1 1/2-inch cubes. Keep cold.
2. Mix marinades in two large containers (food-safe buckets or deep hotel pans).
3. Toss meat thoroughly to coat. Cover and refrigerate 12–24 hours. Stir once halfway.

24–12 Hours Before

1. Grate and drain cucumbers. Mix tzatziki. Chill tightly covered. It tastes better the next day.
2. If using wooden skewers, soak 200–250 in water for 1 hour; drain and store wrapped.

6–3 Hours Before

1. Skewer the meat. Aim for 5–6 ounces raw per skewer.
2. Pull skewers from the fridge 30 minutes before grilling for even cooking.

Grilling and Holding

1. Preheat to medium-high. Oil grates lightly.
2. Cook chicken to 165°F and pork to 145°F, turning for color, ~8–12 minutes depending on heat.
3. Rest 5 minutes. Finish with lemon zest, a squeeze of lemon, flaky salt, and a dusting of oregano.
4. Hold in a warm pan (150–160°F) covered loosely with foil for up to 30–45 minutes.

Serving for a Crowd: Pitas, Sides, and Flow

• Pita: 60–70 pieces. Warm, wrap in clean towels, and replenish often.
• Sides: Greek salad, lemon potatoes, or a bright herb sauce like this chimichurri recipe if you want a second green sauce option.
• Toppings bar: Tzatziki, sliced red onion, tomatoes, cucumbers, parsley, and lemon wedges.
• Traffic flow: Place pitas first, then proteins, then toppings. Sauces last to prevent jams.

Troubleshooting the Ratios

• Too sharp/acidic: Whisk in 1–2 tablespoons olive oil and a pinch of sugar per quart of marinade, or finish grilled meat with more oil instead of more lemon.
• Not garlicky enough: Add garlic powder at the end (it blooms faster than raw garlic). Start with 1/2 teaspoon per 5 pounds cooked meat.
• Dry meat: Switch to thighs/shoulder next time. For now, brush with olive oil and lemon juice as it rests.
• Watery tzatziki: Stir in 2–3 tablespoons strained yogurt or labneh to tighten it up.

From My Kitchen: What Actually Works

I’ve tested salt at the full multiplier and it always tastes too salty after marinating overnight. I scale all ingredients fully except salt, which I scale to about 75% in the marinade and then finish with flaky salt after grilling. Yogurt in chicken marinades speeds browning but scorches if your grill runs hot; medium-high heat delivers better color without bitter spots. For tzatziki, microplaned garlic blooms faster than minced; I use half the amount if serving immediately and the full amount if it rests overnight. Finally, skewering tightly gives uneven cooking — leave small gaps so heat can circulate.

Ingredient Swaps and Add-Ons

• Herbs: Swap oregano with a 50/50 mix of oregano and thyme for pork.
• Citrus: Add 1 tablespoon lemon zest per 10 pounds of meat for deeper lemon without extra acid.
• Dairy-free tzatziki: Use thick coconut yogurt and extra dill; add 1 teaspoon white wine vinegar for tang.
• Extra sauce: A batch of roasted red pepper sauce adds sweetness that pairs well with pork.

Frequently Asked Questions

How much meat do I need for Greek Souvlaki for 50 people?

Plan 28–30 pounds of raw meat total, or about 8–9 ounces raw per person. If serving lots of sides, 25 pounds can work. Mix chicken and pork for variety.

Can I make Greek Souvlaki for 50 ahead of time?

Yes. Marinate meat up to 24 hours in advance and skewer the morning of. Grill close to serving time and hold warm for up to 45 minutes. Tzatziki is best made 1 day ahead.

What’s the best lemon and garlic ratio so it’s not overpowering?

Use 2 tablespoons lemon juice and 1 teaspoon minced garlic per pound of meat, plus 1 tablespoon olive oil. For chicken, add 1 tablespoon yogurt per pound for balance. Finish with lemon zest after grilling instead of more juice.

How long does tzatziki keep in the fridge?

Up to 3 days in a sealed container. It thickens as it chills; stir before serving. If it loosens, fold in a spoonful of strained yogurt.

Can I freeze leftover souvlaki?

Cooked souvlaki freezes well for up to 2 months. Cool completely, wrap tightly, and reheat covered at 325°F with a splash of lemony olive oil. Tzatziki doesn’t freeze well; make it fresh.

What’s the best way to serve souvlaki for a crowd?

Set up a buffet: warm pitas first, then skewers, then toppings and sauces. Keep tzatziki on ice, and refresh small bowls often. Finish meat with flaky salt and lemon at the station for maximum aroma.

The Bottom Line

For consistent, crowd-pleasing souvlaki, stick to clear ratios, salt conservatively in the marinade, and finish boldly after the grill. With a thick, well-drained tzatziki and warm pitas, you’ll feed 50 without breaking a sweat.
