Ingredients
- 1.5 lb large raw shrimp, peeled and deveined (base for 4 portions)
- 1 lb asparagus, trimmed
- 4 tablespoons unsalted butter
- 2 tablespoons olive oil
- 4 cloves garlic, minced
- 2 tablespoons fresh lemon juice
- 1 teaspoon lemon zest
- 1 teaspoon smoked paprika
- 1 teaspoon kosher salt
- 1/2 teaspoon freshly ground black pepper
- 1 tablespoon chopped fresh parsley
- 4 heavy-duty foil sheets, 12 x 18 inches
- 4 lemon wedges for service
Steps
- 1Prep shrimp and vegetables: Pat shrimp dry, remove any shells and tails as preferred. Trim woody ends from asparagus and cut to fit foil sheets. Mince garlic and zest the lemon.
- 2Make garlic lemon butter: In a small saucepan melt butter with olive oil over low heat. Add minced garlic and cook until fragrant but not browned, about 30 seconds. Stir in lemon juice, lemon zest, paprika, salt and pepper. Remove from heat.
- 3Assemble packs: Lay each foil sheet shiny side up. Divide asparagus into four piles in the center of each sheet. Top asparagus with 6 ounces of shrimp per portion. Spoon equal amounts of garlic lemon butter over shrimp and vegetables and sprinkle with parsley.
- 4Seal and cook: Fold foil over and crimp edges to make a sealed packet. Cook on a preheated oven sheet at 400°F for 10 to 12 minutes, or until shrimp reach 145°F internal temperature. For char flavor, finish on a 500°F grill for 1 to 2 minutes with packs slightly open.
- 5Finish and serve: Open packs carefully away from face to release steam. For plated service transfer shrimp and asparagus to warmed plates and garnish with lemon wedge. For takeaway seal and label with reheating and handling instructions.

Tips
- →If scaling to large batches, buy shrimp by the box and plan for 5 to 10 percent yield loss for peel and devein.
- →Use a probe thermometer for first few batches to confirm oven time matches kitchen equipment and adjust times by 1 to 2 minutes.
- →Label takeaway packs with 'keep hot above 135°F' or reheating instructions to reduce complaints.
- →For uniform portions weigh shrimp per pack when training staff until they are consistent.
Overview
Shrimp and asparagus foil packs are fast to prepare, popular for seasonal specials, and ideal for both plated service and takeaway. This guide gives a volume-ready recipe card, clear food safety controls, and concrete cost math so you can price the item profitably whether you sell it on the line or as a packaged to-go special.
Scaling the recipe for production
How to scale reliably
Build your master recipe at a small batch yield then apply a single scale factor. Round practical items such as whole lemons and shrimp counts to the nearest usable unit, and always verify critical liquid volumes to ensure sauce consistency.
Example: scale 4 portions to 50 portions
If the base recipe yields 4 portions and you need 50, multiply ingredient quantities by 12.5. For example a 1.5 pound shrimp base becomes 18.75 pounds of shrimp. Round that to 19 pounds for ordering and plan one extra pound for waste and trim.
Production flow and mise en place
Workstation setup removes slowdowns. Assign one team to trim asparagus and wash, another to peel and devein shrimp, and a third to portion sauce and assemble packs. Pre-portion butter and seasonings into hotel pans so assembly is one-motion per pack. Keep foil sheets stacked by station to maintain rhythm.
HACCP cook and hold rules
Critical temperatures and timing
- Cook shrimp to a minimum internal temperature of 145°F measured at the thickest part.
- Hot-hold prepared packs at 135°F or higher while on-service hot-hold. Use calibrated probes and log temperatures every two hours.
- If cooling for later service, cool from 135°F to 70°F within 2 hours and from 70°F to 41°F within an additional 4 hours.
- Reheat cold-held packs to 165°F within 2 hours before service.
- Follow your local health code for discard times and keep written checks with timestamps for each batch.
Packaging and service options
Decide whether to offer single-portion foil packs for takeaway or to plate in the pass. Packaging choices change labor and material cost so price accordingly.
- Heavy-duty foil single-portion packs with a tamper sticker for delivery.
- Half-sheet catering foil for multiple portions; finish on hotel pans for plated service.
- Compostable clamshell for customers who prefer no foil; add heat-seal bag for transport.
- Paper banding and printed care instructions to reduce returns and complaints.
Portion costing and profit math
Step 1: calculate food cost per recipe
Start with the exact ingredient list for the base yield. Example costs for a 4 portion batch:
Shrimp 1.5 lb at $10.00 per lb = $15.00. Asparagus 1 lb at $3.50 per lb = $3.50. Butter, oil, aromatics and seasoning combined = $1.05. Foil and immediate packing materials = $0.60. Total food cost for 4 portions = $20.65. Food cost per portion = $20.65 divided by 4 = $5.16.
Step 2: add labor and packaging
Estimate labor minutes per portion. For a single takeaway pack assume 6 minutes assembly time. At $15 per hour that is (6/60)*15 = $1.50 labor per portion. Add packaging and handling cost per portion, for example $0.30. Total variable cost per takeaway portion = $5.16 food + $1.50 labor + $0.30 packaging = $6.96.
Step 3: set price using target food cost
Choose a target food cost percentage. Midscale targets commonly use 28 to 35 percent. Using 30 percent as an example, price = total variable cost / 0.30. With the example numbers price = 6.96 / 0.30 = $23.20. Round to a practical menu price such as $23 or $24 and track actual monthly food and labor variance.
Plated vs takeaway example
For plated service reduce packaging cost and assume faster plating labor, for example 2 minutes per plate equals $0.50 labor. Per-plate variable cost = $5.16 + $0.50 = $5.66. At 30 percent target price = $5.66 / 0.30 = $18.87. Round to $19 and test guest acceptance.
Operational checks and small changes with big impact
Swing a 10 cent drop in packaging cost times 500 units per week is $50 saved weekly. Negotiate shrimp price by committing to consistent weekly orders. Reduce plating time by one minute and you reduce hourly labor cost across the run. Track plate times during a single shift to identify bottlenecks.

Frequently Asked Questions
What is the safe internal temperature for cooked shrimp in foil packs?
Cook shrimp to a minimum internal temperature of 145°F. Measure at the thickest part of the shrimp and log readings for each batch.
How long can I hot-hold foil packs for service?
Hot-hold at 135°F or higher. Use temperature logs every two hours and follow your local health code for maximum continuous hold times.
Can I assemble packs in advance and cook to order?
Yes. Pre-assembly is efficient. Hold prepped packs refrigerated at 41°F or lower, then cook to 145°F and service or hot-hold as required. Follow cooling and reheating controls if you cook and chill for later use.
How should I price takeaway versus plated portions?
Calculate per-portion food cost, add labor per portion and packaging. Divide total variable cost by your target food cost percentage to get a menu price. Typical targets are 28 to 35 percent.
Can I prepare these packs ahead of time and refrigerate?
Yes. Assemble cold and refrigerate at 41°F or lower. Cook from chilled to 145°F before service, or follow cooling rules if you cook then chill for later use.
What is a good substitute for shrimp for a non-shellfish option?
Use 6 ounces of boneless skinless chicken thigh or 4 to 5 ounces of firm white fish fillet per portion. Adjust cook times and confirm internal temperature for chicken at 165°F.
