What Is Pickled Shrimp?

Pickled shrimp is a classic Southern dish that dates back generations, particularly popular in Louisiana, Texas, and along the Gulf Coast. Traditionally, shrimp are boiled, then layered with aromatics like onion, garlic, and lemon before being submerged in a vinegar-based brine seasoned with mustard seed, celery seed, peppercorns, and bay leaves.

This Cajun-inspired version takes that classic formula and turns up the heat, quite literally, by adding Cajun seasoning, hot sauce, jalapeño, and crushed red pepper flakes to the mix. The result is a spicier, bolder take on the traditional recipe that still keeps all the tangy, bright, herbaceous qualities that make pickled shrimp so addictive.

Ingredients You’ll Need

Here’s a closer look at what goes into this recipe and why each ingredient matters.

Shrimp: Two pounds of large shrimp, peeled and deveined, form the star of this dish. Using large or jumbo shrimp is ideal since they hold up well in the brine without becoming rubbery or overly small once pickled.

Vinegar and water: The base of the pickling brine. White vinegar delivers that classic tangy bite, while water helps balance the acidity so it doesn’t overwhelm the other flavors.

Olive oil: Adds richness and helps mellow the sharpness of the vinegar, giving the brine a silkier, more well-rounded mouthfeel.

Cajun seasoning: The heart of this recipe’s flavor. A good Cajun seasoning blend typically includes paprika, garlic powder, onion powder, cayenne, oregano, and thyme, delivering that signature smoky, savory, slightly spicy depth.

Pickling salt or kosher salt: Helps season the shrimp and brine while also playing a role in the preservation process. Pickling salt is ideal since it dissolves cleanly without clouding the brine.

Sugar: Just a touch of sugar balances the acidity of the vinegar and rounds out the overall flavor, keeping the brine from tasting too sharp or one-dimensional.

Hot sauce: Adds an extra layer of tangy heat. Feel free to use your favorite brand, whether that’s a classic Louisiana-style hot sauce or something smokier.

Garlic: Thinly sliced garlic cloves infuse the brine with a punchy, aromatic quality that becomes milder and slightly sweet after a day or two of pickling.

Red onion: Adds color, crunch, and a slightly sweet, sharp bite that pairs beautifully with the shrimp and brine.

Jalapeño: Sliced fresh jalapeño brings fresh, bright heat and a pop of color throughout the jar.

Crushed red pepper flakes: Reinforces the spice level and adds little flecks of heat throughout the brine.

Whole black peppercorns: A classic pickling spice that adds warmth and a subtle bite without overwhelming heat.

Mustard seeds and celery seeds: These two seeds are pickling staples, contributing earthy, slightly tangy, aromatic notes that are essential to that classic pickled shrimp flavor profile.

Bay leaves: Infuse the brine with a subtle herbal depth as it heats and cools.

Lemon: Thin lemon slices add brightness, acidity, and a beautiful pop of color to the jar.

Fresh parsley: Chopped parsley adds a fresh, herbaceous finish that lightens up the richness of the dish.

How to Make Cajun Pickled Shrimp

This recipe comes together in just a few simple steps. Here’s the full breakdown.

Step 1: Cook the Shrimp

Bring a large pot of lightly salted water to a gentle boil. Add the shrimp and cook for just 2 to 3 minutes, or until they turn pink and are fully cooked through. Shrimp cook incredibly fast, so keep a close eye on them. Overcooked shrimp can turn rubbery, so pulling them the moment they turn opaque and pink is key.

As soon as they’re done, drain the shrimp immediately and transfer them to an ice bath. This stops the cooking process instantly and helps the shrimp retain a tender, juicy texture. Once cooled, drain well to remove excess water.

Step 2: Layer the Jar

Place the cooked shrimp into a large, clean glass jar, or divide them evenly between two quart-sized jars if you prefer smaller portions. Nestle the garlic slices, red onion, jalapeño, lemon slices, and chopped parsley throughout the shrimp. Layering these aromatics directly among the shrimp ensures every bite gets infused with flavor.

Step 3: Make the Pickling Brine

In a saucepan, combine the white vinegar, water, olive oil, Cajun seasoning, pickling salt, sugar, hot sauce, crushed red pepper flakes, black peppercorns, mustard seeds, celery seeds, and bay leaves.

Heat the mixture over medium heat, stirring frequently, just until the salt and sugar fully dissolve. It’s important not to let the brine come to a boil, since boiling can dull some of the fresh, bright flavors from the spices and citrus.

Step 4: Pour and Cool

Carefully pour the warm brine over the shrimp, making sure everything is completely submerged. This is important, since any shrimp or aromatics left exposed above the liquid line won’t pickle evenly and could spoil faster.

Let the jars cool to room temperature on the counter before sealing them tightly with lids. Sealing while the brine is still hot can cause condensation buildup inside the jar, which isn’t ideal for texture or freshness.

Step 5: Chill and Pickle

Refrigerate the jars for at least 24 hours before serving to allow the flavors to develop. For the boldest, most flavorful result, let the shrimp pickle for 2 to 3 days. The longer they sit, the more intense and well-rounded the Cajun flavor becomes.

Tips for the Best Cajun Pickled Shrimp

Use fresh, high-quality shrimp. Since shrimp is the star of the dish, starting with fresh or high-quality frozen shrimp (properly thawed) makes a noticeable difference in texture and flavor.

Don’t skip the ice bath. Shocking the shrimp in ice water immediately after boiling is essential for locking in that firm, tender bite rather than a mushy or overcooked texture.

Keep everything submerged. Make sure the shrimp and aromatics stay fully covered in brine the entire time they’re pickling. If needed, you can weigh them down slightly with a small clean dish or use a smaller jar to reduce empty space.

Adjust the heat to your taste. If you prefer a milder version, reduce or omit the jalapeño and crushed red pepper flakes. For extra heat, add an additional jalapeño or a spicier hot sauce.

Let it sit for maximum flavor. While the shrimp are technically ready after 24 hours, the flavor truly deepens after 2 to 3 days. If you can plan ahead, it’s worth the wait.

Shake or stir gently once a day. Gently turning the jar once a day helps redistribute the spices and brine evenly throughout the shrimp.

Serving Suggestions

Cajun pickled shrimp is incredibly versatile and can be served in a variety of ways:

• Serve chilled straight from the jar as a stand-alone appetizer with toothpicks for easy grabbing.
• Pair with crusty bread or crackers to soak up the flavorful brine.
• Add on top of a fresh green salad for a spicy, tangy protein boost.
• Serve alongside a chilled seafood platter for parties and gatherings.
• Spoon over avocado toast for a spicy, zesty twist on a brunch favorite.
• Include as part of a Southern-style charcuterie or seafood board.

This dish also makes a fantastic gift when packaged in a decorative jar, perfect for holiday get-togethers or as a hostess gift.

Storage Information

Store the Cajun pickled shrimp in an airtight jar in the refrigerator for up to 5 days. It’s important to keep the shrimp completely submerged in the pickling brine the entire time to maintain the best flavor and freshness.

Do not freeze this dish after pickling. Freezing can drastically alter the texture of both the shrimp and the fresh vegetables, resulting in a mushy, unappetizing consistency once thawed.

Frequently Asked Questions

Can I use pre-cooked shrimp for this recipe? Yes, you can use pre-cooked shrimp to save time. Simply skip the boiling step and go straight to layering the shrimp with the aromatics before pouring over the brine. Keep in mind that pre-cooked shrimp may have a slightly different texture compared to freshly boiled shrimp.

How spicy is this recipe? This recipe has a moderate to bold level of heat thanks to the Cajun seasoning, jalapeño, hot sauce, and crushed red pepper flakes. If you prefer a milder version, you can reduce or omit the jalapeño and red pepper flakes, or use a milder hot sauce.

Can I make this recipe without alcohol or overly strong vinegar taste? This recipe doesn’t contain alcohol. If you find white vinegar too sharp, you can substitute a portion of it with apple cider vinegar or rice vinegar for a slightly milder, rounder flavor.

What size shrimp works best? Large shrimp work best for this recipe since they hold up well in the brine and provide a satisfying, meaty bite. Avoid using very small shrimp, as they can become overly soft during the pickling process.

Can I double this recipe? Absolutely. This recipe scales up easily. Simply double the ingredients and divide the shrimp and brine among additional jars as needed.

Is this recipe gluten-free? Most of the ingredients in this recipe are naturally gluten-free, but be sure to check the label on your Cajun seasoning and hot sauce, since some blends may contain gluten-based additives or anti-caking agents.

How long does it take before the shrimp are ready to eat? The shrimp need to chill in the refrigerator for at least 24 hours before serving. For the best, boldest flavor, allow them to pickle for 2 to 3 days.
