Ingredients for trader joe's argentine shrimp

Six ingredients make the magic happen—crispy shrimp with that signature Trader Joe's garlic butter sizzle.

The shrimp are the star, so size matters. Grab the 16-20 count at Trader Joe's—they're pre-peeled and deveined, saving you time. If buying elsewhere, check for tails-on (they look better plated) and avoid the tiny 31-40 count. For the cornmeal, Bob's Red Mill is my go-to—it's fine enough to coat properly without clumping. The butter needs to be cold when you cube it, or it'll melt into a greasy mess. I always buy Plugrá unsalted from Trader Joe's—it's European-style and melts beautifully. Fresh garlic is non-negotiable here; the pre-minced stuff in jars has no flavor.

No cornmeal? Panko breadcrumbs work in a pinch, but the texture won't be quite the same. Short on butter? Olive oil or avocado oil can replace half of it, but you'll lose that rich sizzle. The chimichurri sauce can be store-bought (I like Trader Joe's or Whole Foods brands), but homemade is worth it—just parsley, garlic, olive oil, and red wine vinegar. For extra crunch, toss the shrimp in cornmeal twice before frying. And if you're feeling fancy, add a pinch of smoked paprika to the cornmeal mix for depth. The red pepper flakes? Only if you want heat—skip them if you're serving kids or sensitive eaters.

This dish reheats beautifully—just 5 minutes in a 350°F oven with a splash of water to keep it moist. Store leftovers in the fridge for 2 days, covered tightly to keep that crisp. For freezing, fry the shrimp, let them cool completely, then freeze on a tray before transferring to a bag. They'll keep for 1 month. I always make a double batch because it disappears fast—great for meal prep or entertaining. Serve with crusty bread to soak up that garlicky butter sauce.

Step-by-step instructions for garlic butter shrimp with crispy cornmeal crust

Here's how to recreate that irresistible Trader Joe's Argentine shrimp at home—crispy, garlicky, and packed with flavor.

Pat the 1.5 lb large shrimp dry with paper towels—this is non-negotiable for a proper crust. I like to work with them in batches to avoid overcrowding later. In a shallow bowl, mix together the 1 cup yellow cornmeal, 1.5 tsp salt, 0.5 tsp ground black pepper, and 0.25 tsp red pepper flakes. Toss the shrimp in this seasoned cornmeal until they're completely and evenly coated.

Here's the thing—don't rush the coating. You want every inch of shrimp covered so that crispy crust forms all around. If you're feeling fancy, you can lightly dust them with the 0.25 cup all-purpose flour after the cornmeal for an extra-crispy texture. Let the coated shrimp rest for 10 minutes while you prep the garlic butter.

In a large skillet, heat the 0.5 cup vegetable oil over medium heat until it shimmers—this should take about 2 minutes. While the oil heats, melt the 0.5 cup unsalted butter in a separate small saucepan over low heat. As the butter melts, add the 6 minced garlic cloves and let them cook gently for 1 minute until fragrant but not browned.

This is where the magic happens: the garlic should perfume the butter without burning. If you see any brown spots developing, immediately remove the pan from heat. Keep this garlic butter warm while you get the shrimp ready to cook—it'll be the perfect finishing touch.

Working in batches to avoid overcrowding, carefully add the cornmeal-coated shrimp to the hot oil. Cook for 1-2 minutes per side until they turn a beautiful golden brown color. You'll know they're ready when they release easily from the pan and the cornmeal crust looks crispy and set.

Don't walk away during this step—shrimp cook fast, and you want that perfect golden crust. If you see any shrimp that aren't browning evenly, gently press down on them with a spatula for better contact with the hot oil. Once all shrimp are cooked, remove them from the oil and drain on a wire rack or paper towels.

Return the skillet to medium-low heat and add the garlic butter you prepared earlier. Let it warm through for about 30 seconds, then immediately add the cooked shrimp back to the pan. Toss everything together for 1 minute to coat the shrimp in that fragrant garlic butter.

In a separate bowl, combine the 0.5 cup chimichurri sauce with the 2 tbsp freshly squeezed lemon juice and 0.125 cup chopped fresh parsley. Spoon this vibrant green sauce over the shrimp and toss gently to combine. The chimichurri will add a bright, herby contrast to the rich garlic butter.

Transfer the shrimp to a serving platter and garnish with any remaining chimichurri and extra chopped parsley. Serve right away while the crust is still crispy and the garlic butter is warm. I like to pair these with crusty bread to soak up all that delicious sauce.

Each bite should deliver that perfect combination of crispy cornmeal crust, tender shrimp, and layers of garlic and herb flavors. The secret to this dish is in the timing—keep everything moving quickly so you maintain that perfect texture contrast between the crispy exterior and tender interior.

Dietary considerations for this recipe

Gluten-Free Adaptations

This recipe is naturally gluten-free since it relies on cornmeal and shrimp, but I always double-check the chimichurri ingredients. Store-bought chimichurri from Trader Joe's or Whole Foods typically contains no gluten, but homemade versions using flour-based thickeners might.

For a foolproof approach, make your own chimichurri with just parsley, garlic, olive oil, and red wine vinegar—no gluten needed. 🌱

Low-Carb Options

To keep this dish low-carb while maintaining the cornmeal crust, I recommend using almond flour or coconut flour instead of regular cornmeal. Mix ½ cup almond flour with ½ cup cornmeal for a lighter texture that still delivers that crispy bite.

The almond flour adds a subtle nuttiness that pairs beautifully with the garlic butter. Always check your almond flour for gluten-free certification if needed.

Shellfish Allergies

For those avoiding shrimp but craving the same flavors, try large scallops or white fish fillets like cod or halibut. Cut scallops into similar-sized pieces and follow the same cornmeal coating and frying technique. The texture will be slightly different, but the garlic butter and chimichurri will still shine.

I've tested this with 12 oz scallops and found the cooking time reduces to 45 seconds per side for perfect doneness. 🦑

Dairy-Free Substitutions

The butter is the heart of this dish, but you can easily adapt it for dairy-free diets. Replace the ½ cup butter with ½ cup dairy-free butter (I recommend Miyoko's or Earth Balance) or olive oil.

For extra richness, blend ¼ cup olive oil with ¼ cup dairy-free butter. The flavor will be slightly different but still delicious—just skip the chimichurri if you're sensitive to garlic in oil-based sauces.

Spice-Free Version

If you're avoiding heat or serving sensitive eaters, simply omit the red pepper flakes from the cornmeal mixture. The dish will still be flavorful with just the salt and black pepper.

For extra brightness, add a pinch of citric acid (available at baking stores) to the cornmeal—it enhances flavor without adding heat. I've found this trick works especially well when serving to kids or those with spice sensitivities. 🌶️

Protein Upgrades

For a higher-protein version, add 1 tbsp nutritional yeast to the cornmeal mixture—it adds a cheesy, umami depth while boosting protein content. Alternatively, serve the shrimp alongside grilled chicken skewers or seared salmon for a complete protein meal.

I've tested this with 6 oz grilled chicken breast per person and found it pairs perfectly with the shrimp's bold flavors. 💪
