Does frozen shrimp have gluten?

Gluten is a protein found in grains like wheat, barley, and rye. For people with celiac disease or gluten sensitivity, consuming gluten can cause negative health effects. Many people follow gluten-free diets and want to know if frozen shrimp contains this problematic protein. Here is a comprehensive look at whether different types of frozen shrimp have gluten.

What is Gluten?

Gluten is a general name for the proteins found in wheat, rye, barley and triticale. The two main proteins that make up gluten are:

  • Gliadin
  • Glutenin

When flour and water are combined and kneaded, these two proteins form elastic strands that give bread, pasta, and other baked goods their chewy texture and help them hold their shape.

For most people, gluten poses no health concerns. However, for those with celiac disease or non-celiac gluten sensitivity, gluten triggers an abnormal immune response that damages the small intestine. Even small amounts of gluten in foods can cause symptoms like diarrhea, bloating, fatigue, and joint pain in sensitive individuals.

Following a strict lifelong gluten-free diet is the only treatment for celiac disease. Limiting or eliminating gluten may also help improve symptoms for those with gluten sensitivity.

Many people also choose to follow a gluten-free diet in an effort to generally improve health or lose weight, although there is limited evidence that this works for those who do not have gluten intolerance.

Does Shrimp Naturally Contain Gluten?

Shrimp, in its natural raw form, does not contain gluten.

Shrimp are crustaceans with an exoskeleton. Like other types of seafood and meat, they do not naturally contain gluten proteins.

So raw, fresh shrimp are inherently gluten-free. Frozen shrimp, as long as it has only been frozen without any additives, also does not contain gluten.

Can Frozen Shrimp Pick Up Gluten During Processing?

While raw shrimp is gluten-free, sometimes frozen shrimp products may pick up traces of gluten during processing and freezing. Here are some ways gluten could inadvertently get into frozen shrimp:


Some frozen shrimp products are breaded or coated in batter to create a crunchy exterior when cooked. Bread crumbs or batter coatings can contain gluten from wheat flour or bread ingredients.

Always check the ingredient list carefully and do not consume breaded shrimp products if you are avoiding gluten. Opt for plain frozen shrimp with no coatings.

Marinades & Sauces

Many frozen shrimp products are pre-marinated or come with sauce packets. These marinades and sauces often contain thickening agents like wheat flour or contain soy sauce, which is typically made from wheat.

Be cautious of marinated frozen shrimp or products that come with a sauce on the side, unless they are labeled gluten-free.

Shared Equipment

There is a chance of cross-contamination if the facility that processes and freezes the shrimp also processes gluten-containing foods on the same equipment. Bits of gluten could get transferred to the shrimp.

Your safest bet is to look for frozen shrimp that is labeled gluten-free, which indicates the facility takes measures to prevent cross-contamination.

Added Stabilizers & Binders

Some additives are occasionally mixed into certain frozen shrimp products to help preserve juiciness and bind the shrimp into a desired shape. These stabilizers and binders can sometimes contain gluten.

One example is wheat protein isolate, which may be used an additive in some types of reconstituted shrimp products. Check the ingredients and avoid any frozen shrimp containing questionable additives.

How to Find Gluten-Free Frozen Shrimp

When purchasing frozen shrimp, read labels carefully and watch out for potential sources of gluten like breading, marinades, and questionable additives.

Here are some tips for finding gluten-free frozen shrimp:

– Opt for plain frozen shrimp with no coatings or sauces
– Check that the ingredients just list “shrimp” without additives
– Look for packages marked “gluten-free”
– Purchase reputable brands that indicate allergen-free facilities and equipment
– If unsure, contact the manufacturer to ask about potential cross-contamination

Some gluten-free frozen shrimp brands include:

  • SeaPak
  • AquaStar
  • Keyport
  • Trader Joe’s
  • 365 by Whole Foods

When dining out, check with your server or the restaurant about how frozen shrimp dishes are prepared. Request plain grilled or steamed shrimp, without breading or sauces containing gluten.

Common Questions

Here are answers to some frequently asked questions about whether different types of frozen shrimp contain gluten:

Do frozen cooked shrimp have gluten?

Plain frozen cooked shrimp that only contains shrimp as the ingredient should not have gluten. However, avoid frozen cooked shrimp with any sauces or marinades, which may contain gluten.

Does frozen shrimp tempura have gluten?

Yes, frozen tempura shrimp likely contains gluten since tempura batter typically contains wheat flour. Always avoid breaded shrimp products if you have a gluten allergy.

Can you bread frozen shrimp with gluten-free breadcrumbs?

Yes, you can coat frozen shrimp in gluten-free breadcrumbs before cooking. Use breadcrumbs made from gluten-free grains like rice, quinoa, or oats. This allows you to enjoy the breaded texture while avoiding gluten.

Do frozen shrimp skewers have gluten?

Plain frozen shrimp skewers without sauces or coatings should be gluten-free. However, avoid any frozen shrimp skewers containing marinades, which may have soy sauce or other gluten-containing ingredients.

Is frozen shrimp fried rice gluten-free?

It depends. Plain frozen shrimp should be fine, but many frozen shrimp fried rice products contain soy sauce (made from wheat) or other questionable additives and sauces. Check the ingredients carefully and look for a gluten-free label before consuming.

Healthiest Ways to Cook Frozen Shrimp

Once you’ve purchased some gluten-free frozen shrimp, try these healthy cooking methods:


Thaw the frozen shrimp and grill them plain, brushed lightly with olive oil. Throw them on a clean grill for just 2-3 minutes per side until opaque and lightly charred.

Top grilled shrimp with your favorite gluten-free sauce like chimichurri or harissa for extra flavor.


Thaw the shrimp and sauté with olive oil, garlic, lemon juice, and gluten-free seasoning of choice. Cook over medium high just until pink and cooked through, about 2-3 minutes per side.

Shrimp Skewers

Make a marinade of olive oil, lime juice, minced garlic, chili powder, cumin, and cayenne. Marinate thawed shrimp for 30 mins-1 hour, then thread onto skewers and grill or broil for 2-3 minutes per side.

Cajun Shrimp

Season thawed shrimp with Cajun seasoning. Sauté in olive oil with bell pepper and onions until shrimp is pink and vegetables are tender, about 5 minutes. Serve over brown rice.

Shrimp & Veggie Foil Packs

Place thawed shrimp with chopped veggies like zucchini and cherry tomatoes on a foil sheet. Drizzle with olive oil and gluten-free seasoning. Seal foil and bake at 400F for 12-15 minutes.

Coconut Shrimp

Toss thawed shrimp in beaten eggs and coconut flakes. Bake at 425F for 12 minutes until golden brown. Serve with mango salsa or sweet chili sauce for dipping.


In conclusion, raw fresh shrimp and plain frozen shrimp without additives or processing do not naturally contain gluten. However, certain frozen shrimp products may pick up traces of gluten during processing depending on added ingredients or cross-contamination risks.

When buying frozen shrimp, read labels carefully and look for gluten-free labels to find safe options if you are avoiding gluten. With the right brand, frozen shrimp can be a great gluten-free addition to all types of healthy seafood meals and recipes.
