According to the FDA, many healthy adults should aim for at least two servings of seafood per week. When cooking a delicious mixed seafood dish, knowing how much mixed seafood per person to buy is crucial for both budget and flavor. The ideal portion depends heavily on the dish's role, the appetite of your guests, and what other components are being served.

Quick Summary

The quantity of mixed seafood to serve per person varies significantly based on whether it is an appetizer or main course. Factors like guest appetite and dish components influence calculations, especially for meals such as paella or pasta. Adjusting portion sizes based on the meal type ensures a satisfying dining experience for all.

Key Points

Start with Raw Weight: Most serving recommendations are based on the raw, uncooked weight of the seafood.
Entrée vs. Appetizer: Plan for a more generous 6-8 ounces per person for a main course, and a lighter 3-4 ounces for an appetizer.
Consider the Meal's Context: For mixed dishes like paella or pasta, use less seafood per person since other ingredients are filling.
Factor in Guest Appetites: Adjust portion sizes based on whether your guests are heavy or light eaters.
Account for Non-Edible Parts: If using seafood with shells like mussels or prawns, remember the edible meat yield is lower than the total weight.
Visual Cue: A cooked main course serving of seafood is roughly the size of a deck of cards.

Your Guide to Calculating Mixed Seafood Portions

Planning a meal with mixed seafood is a delightful culinary experience, but getting the portions right is key to its success. Serving too little can leave guests hungry, while too much can lead to unnecessary food waste. The raw weight is the most reliable measurement to use, as seafood loses volume during cooking. A good rule of thumb is to start with a basic calculation and then adjust based on context, such as the event type and your guests' preferences.

Standard Portions: Appetizer vs. Main Course

The most important distinction to make when calculating your seafood needs is whether it will be the star of the show or a supporting role. For a mixed seafood platter served as a main dish, a more generous portion is expected compared to when it's part of a paella or a pasta sauce.

For a main course: Aim for approximately 6 to 8 ounces (170 to 227 grams) of raw mixed seafood per person. This quantity is suitable for seafood boils, mixed seafood grills, or a hearty platter where the seafood is the primary protein.
For an appetizer or starter: Reduce the portion to about 3 to 4 ounces (85 to 113 grams) of raw mixed seafood per person. This smaller amount allows guests to enjoy the flavor without becoming too full before the main meal.

Factors That Influence Serving Sizes

While the main course versus appetizer distinction is a great starting point, several other factors can and should influence your final decision. By taking these into account, you can more accurately gauge your guests' appetite and ensure a perfect outcome.

Other ingredients: For dishes like paella, pasta, or stir-fries, the seafood is combined with other filling ingredients like rice, noodles, and vegetables. This means you can reduce the amount of seafood per person. For a seafood pasta, you might use 4 to 6 ounces (113 to 170 grams) per person.
Appetite of guests: Consider the general appetites of the people you are serving. If you are hosting a group of big eaters, you may want to err on the side of a larger portion. For a group of smaller eaters, the lower end of the recommended range is likely sufficient.
Accompaniments: If you are serving a mixed seafood main with plenty of side dishes—such as potatoes, salad, and bread—guests may consume less seafood. Conversely, if the seafood is the centerpiece with minimal sides, a larger portion is wise.
Type of seafood: The specific seafood components matter. For example, mussels in the shell have a much lower meat yield than peeled shrimp. If your mix contains a lot of shellfish with shells, you will need more weight overall to achieve the same amount of edible protein.

Calculating for Specific Mixed Seafood Recipes

Mixed Seafood Paella

For a seafood paella, the rice and other ingredients form the bulk of the meal. A typical recipe serving 4-6 people may use 400 grams of frozen seafood mix, which translates to roughly 70-100 grams per person. When using raw, individual components, consider the following for a robust paella:

Shell-on prawns: Approximately 100-150 grams per person.
Squid rings: 50-75 grams per person.
Mussels in shell: 125-200 grams per person.
White fish chunks: 75-100 grams per person.

Seafood Stir-Fry

A stir-fry also uses a combination of ingredients, allowing for a more moderate seafood portion. A good starting point is 3 to 4 ounces (85 to 113 grams) of mixed seafood per person. Since the ingredients are chopped into smaller, bite-sized pieces, this amount is visually satisfying and ample when combined with vegetables and noodles.

Portioning for Different Contexts: Table Comparison


Meal Context	Suggested Raw Weight (Per Person)	Notes
Hearty Main Course	6-8 oz (170-227 g)	Ideal for seafood platters, grills, or seafood boils where it's the main attraction.
Seafood Pasta	4-6 oz (113-170 g)	The pasta and sauce fill out the meal, so less seafood is needed.
Paella or Rice Dish	3-5 oz (85-142 g)	The bulk of the meal comes from the rice and other ingredients.
Light Appetizer	3-4 oz (85-113 g)	A smaller serving to kick off the meal.

Tips for Success

When in doubt, buy more: If you are unsure of your guests' appetites or the event is casual, it's always safer to buy a little extra. Leftover cooked seafood can be used in other dishes like salads, soups, or stews.
Account for yield: Remember that some seafood, like mussels or shell-on prawns, have a lower meat yield compared to scallops or fish fillets. For a precise calculation, consider the ratio of meat to shell.
Visually portion: If you're serving buffet-style, portioning by weight isn't always practical. Visually, a main course portion of cooked seafood is about the size of a deck of cards.
Talk to your fishmonger: Don't be afraid to ask for advice. A good fishmonger can provide specific recommendations based on the type of mixed seafood and how you plan to prepare it.

Conclusion

Determining how much mixed seafood per person is not a one-size-fits-all formula but a calculation based on the meal's role and accompanying dishes. By using the general guidelines of 6-8 ounces for a main course and 3-4 ounces for an appetizer, and adjusting for other factors, you can confidently prepare a delicious and perfectly portioned meal. Careful planning ensures that everyone enjoys a satisfying amount of fresh, flavorful seafood without any last-minute stress or waste.
