Lawry’s Seasoned Salt is the secret weapon here. Grab the jarred version—it’s got that perfect balance of salt, garlic, and onion powder already. If you can’t find it, Diamond Crystal kosher salt plus 1/4 tsp onion powder and 1/4 tsp garlic powder works as a substitute. For the smoked paprika, Penzeys or McCormick are my go-tos, but any quality smoked variety will do. The cayenne? Don’t skimp—this is where the heat comes from. If you’re sensitive to spice, start with 1/2 tsp and adjust. The olive oil should be fruity and high-quality—California Extra Virgin brands like Corto or Colavita elevate everything.

No Lawry’s Seasoned Salt? Mix 1 tsp kosher salt, 1/4 tsp garlic powder, and 1/4 tsp onion powder. Short on smoked paprika? Regular paprika plus a pinch of liquid smoke gets you close. Fresh thyme is ideal but dried works at one-third the amount. The lemon juice can be bottled, but freshly squeezed has that bright punch that makes all the difference. For the proteins, chicken breasts should be pounded to even thickness for consistent cooking, while shrimp should be tossed in marinade for just 10-15 minutes max—they cook fast and can get rubbery. Balsamic vinegar adds that tangy depth that balances the smoky spices perfectly.

This marinade keeps beautifully in the fridge for up to 2 weeks in an airtight container. For best results, marinate proteins for 30 minutes to 2 hours—no need to overdo it. The chicken and shrimp will reheat well, but I always recommend grilling or baking fresh for that perfect char. If you make extra marinade, freeze it in ice cube trays for up to 6 months. Just thaw overnight in the fridge before using. The flavors only get better as they meld together, so don’t be afraid to make a big batch for your next backyard cookout.

Step-by-step instructions for lawry’s Louisiana red pepper marinade recipe

Here’s how to blend this fiery marinade and transform your grilled meats into Cajun masterpieces.

In a medium bowl, whisk together the 1 tablespoon Lawry’s Seasoned Salt, 1 tablespoon Smoked Paprika, 1 teaspoon Cayenne Pepper, ½ teaspoon Ground Black Pepper, ½ teaspoon Onion Powder, ½ teaspoon Dried Thyme, and ½ teaspoon Ground Cumin. This dry blend forms the aromatic backbone of your marinade, delivering that signature Louisiana heat and depth.

Use a wire whisk for 30 seconds to ensure the spices are evenly distributed and no clumps remain. The Lawry’s Seasoned Salt here acts as a flavor multiplier—its savory notes balance the cayenne’s sharpness while the smoked paprika adds that essential smoky character. I like to press the spices through a fine-mesh strainer after whisking to eliminate any potential grit that could irritate delicate shrimp later.

To the dry spice mixture, add the ½ cup Extra-Virgin Olive Oil, ¼ cup Lemon Juice, 1 tablespoon Brown Sugar, 1 tablespoon Balsamic Vinegar, and the 4 peeled, roughly chopped Garlic Cloves. Stir vigorously with a wooden spoon until everything is fully combined—you should see the mixture emulsify slightly as the oil and lemon juice begin to bind.

The brown sugar here serves a dual purpose: it caramelizes slightly during grilling, adding a subtle sweetness that cuts through the heat, while also helping the marinade cling to the meat. The balsamic vinegar introduces a tangy complexity that rounds out the acidity from the lemon juice. Give it one final taste—adjust cayenne if you prefer more or less heat, but remember this marinade builds flavor during cooking.

Divide the marinade evenly between two separate containers. Place the 1½ pounds Chicken Breast in one container and the 1 pound Shrimp in the other, ensuring each piece is fully coated. For the chicken, I recommend cutting each breast into 4-6 ounce portions—this ensures even cooking and better marinade penetration.

Marinate the chicken for at least 4 hours (overnight is ideal) in the refrigerator, while the shrimp only needs 30 minutes to 1 hour—any longer and the acidity can start to “cook” the shrimp. Here’s the thing: the chicken benefits from prolonged marination as the spices penetrate deeply, while shrimp absorbs flavor quickly but becomes mushy if over-marinated. Don’t skip the refrigeration—this prevents bacterial growth and allows the flavors to meld properly.

Preheat your grill to medium-high heat (about 375°F) and clean the grates thoroughly. Grill the chicken for 6-8 minutes per side until the internal temperature reaches 165°F and the juices run clear. For the shrimp, cook for 2-3 minutes per side until they turn opaque pink and develop grill marks—overcooking turns them rubbery.

Here’s where the marinade’s magic happens: as the sugars caramelize and the spices toast, they create that iconic smoky char while keeping the meat juicy. I like to baste the chicken with any leftover marinade in the last 2 minutes of cooking to intensify the flavor. Let the chicken rest for 5 minutes before slicing—this ensures juices redistribute, while shrimp can be served immediately. The result should be tender, flavorful meat with a perfect balance of heat, smokiness, and tang.

Common mistakes when making perfect results

Over-Marinating Shrimp

This is the most common mistake I see—letting shrimp sit in the marinade for more than 1 hour. The acidity in the lemon juice and vinegar can actually “cook” the shrimp prematurely, turning them mushy and losing their delicate texture.

Stick to 30 minutes max for shrimp, and always marinate them in the fridge. If you’re short on time, just toss them in for 10-15 minutes—they’ll still absorb plenty of flavor! 🦐

Skipping the Straining Step

I know it’s tempting to skip pressing the dry spices through a fine-mesh strainer, but those tiny spice particles can irritate your mouth—especially when eating shrimp. A quick straining step ensures a smooth marinade without any gritty surprises.

Use a fine-mesh sieve and gently press the spices through with a spoon. It takes 30 seconds and makes all the difference!

Ignoring Protein Thickness

Chicken breasts vary in thickness, and uneven cooking leads to dry spots. Cut each breast into 4-6 ounce portions and pound them to ¼-inch thickness before marinating.

This ensures even cooking and better marinade penetration. I use a rolling pin or the bottom of a glass bottle for this step—it’s quick and effective! 💪

Not Adjusting Heat Levels

The cayenne pepper is where the heat comes from, but everyone has different spice tolerances. If you’re sensitive to heat, start with just ½ tsp cayenne instead of the full 1 tsp.

Taste the marinade before applying it—you can always add more later, but you can’t take it away! Honestly, this is my favorite part of the process—tailoring the heat to your preference.

Undercooking the Chicken

Chicken needs to reach an internal temperature of 165°F for safety, but many people pull it off the grill too soon. Use a meat thermometer—I swear by the Thermoworks Smoke model.

The marinade adds moisture, so it’s easy to forget that the chicken still needs to cook through completely. Let it rest for 5 minutes after grilling to ensure juices redistribute evenly.

Overlooking Marinade Cling

If your marinade isn’t sticking to the meat, it’s not clinging properly. The 1 tbsp brown sugar in the recipe helps, but you can also lightly pat the proteins dry with a paper towel before marinating.

This removes excess moisture that would prevent the marinade from adhering. A quick pat also helps the spices penetrate better during cooking. 🔥
