It’s Always the Right Time for Cajun Shrimp Scampi

Cajun shrimp scampi builds on the traditional Italian-American dish by adding Cajun trinity veggies and South Louisiana seasonings. These extra touches create a deeper, more pronounced flavor than the norm and add a more interesting, varied texture.

My original take on this recipe overflows with shrimp, boasting at least one, but often two, in each bite. There’s also lots of butter for creaminess, plenty of parsley for color, and just a touch of chicken broth to let the naturally dominant shrimp flavor shine right through the sauce.

Best of all, you really can prep and cook this dish in about an hour. So, this is the perfect recipe for feeding your brood a super-tasty weeknight dinner or a weekend comfort-food meal. Indeed.

What to Serve with Cajun Shrimp Scampi

Cajun shrimp scampi makes an excellent meal on its own, especially with freshly cooked pasta. However, you can jazz it up with a side dish or two, depending on what you have on hand.

Cajun-smothered green beans with sausage complement the taste and texture of this shrimp scampi perfectly. The luscious, slow-cooked side lends a homey feel to the meal, making it suitable for large family dinners.
Corn maque choux is another classic Cajun dish that adds just the right amount of captivating crunch to the meal. It boasts a sophisticated presentation, making it the perfect side for the scampi for upscale potlucks and intimate, romantic dinners.
Gluten free butter swim biscuits bring warmth and additional sustenance to the Cajun shrimp scampi main dish. Therefore, this pairing is ideal for serving at potlucks and other rustic, low-key family functions.
Roasted broccoli and cauliflower are a light yet highly flavorful side dish that bakes in the oven while you prepare the scampi on the stove. It’s perfect for adding just that little bit of something extra to the meal with minimal effort on your part.

Storage

Store the leftover Louisiana Cajun shrimp scampi in an airtight container in the refrigerator for up to three days.

Freezing

I don’t fully recommend freezing this dish because the shrimp often become rubbery upon thawing. However, if you want to give it a try, vacuum-seal the leftover scampi in bags to remove as much air as possible. Then thaw and consume them within 2 months for the best taste and texture.

Reheating

You can reheat this dish in the microwave in 45-second intervals, stirring after each one. You can also reheat it on the stove, but you may need to add a bit more chicken broth to prevent it from drying out.

Safety

Use an instant-read thermometer to ensure the shrimp reach an internal temperature of 145 degrees Fahrenheit before removing them from the heat.

Ingredients & Substitutions

Large shrimp, about 21/25 count, are the perfect size for this Cajun shrimp scampi recipe. That said, you can use any size shrimp that you have on hand. The smaller the shrimp, the faster they will cook in the sauce. So, if you do use small shrimp, keep a close eye on the scampi, and remove the skillet from the heat as soon as they curl into a C shape.
The Cajun trinity veggies of chopped onion, green bell pepper, and celery, and the garlic create the South Louisiana culinary style foundation to this dish. Use them all to experience this recipe as intended. However, if you only have onion and garlic on hand, you can still proceed with the recipe and end up with a super tasty homemade shrimp scampi.
Freshly squeezed lemon juice, fresh parsley leaves, and chicken broth work together with the butter to create the Cajun shrimp scampi sauce. If you don’t have fresh parsley on hand, you can reconstitute dried parsley flakes by submerging them in water for a few minutes, then draining them right before use.
The lemon zest, paprika, salt, black pepper, and cayenne first season the shrimp, then distribute the spices throughout the remaining ingredients during the final stage of the Cajun shrimp scampi-making process. Therefore, season the shrimp with as much salt, pepper, and cayenne as desired for the entire dish, not just the shrimp. Use restraint with the spices the first time you make the dish to ensure you do not overseason the scampi; taste and add more spices at the end of the cooking time, if desired.
Parmesan cheese enhances the taste and texture of the Cajun shrimp scampi, lending a rich, slightly nutty flavor to the sauce. It’s an optional ingredient, but one I highly recommend adding to each individual bowl right before serving.

For the Seasoned Shrimp

2 pounds large fresh shrimp, peeled and deveined 21/25-count is the ideal size
2 teaspoons lemon zest
½ teaspoon dried paprika
salt, black pepper, and cayenne pepper to taste I used about ½ teaspoon salt, ¼ teaspoon black pepper, and ¼ teaspoon cayenne

For the Cajun Shrimp Scampi

3 tablespoons avocado oil or high-heat olive oil
1 large yellow onion, chopped
1 large green bell pepper, chopped
2 fresh celery ribs, cleaned, trimmed of white ends and chopped
1 tablespoon minced garlic

¼ cup lemon juice freshly squeezed is best
1 cup chicken broth
¼ cup fresh parsley leaves, chopped
Parmesan cheese for serving, optional

Cook ModePrevent your screen from going dark

Season the shrimp with the lemon zest, paprika, salt, black pepper, and cayenne pepper to taste. Set aside.
Pour the oil into a deep, large skillet or Dutch oven set over medium heat, then add the chopped onion, green bell pepper, and celery. Cook until browned.
Add the minced garlic to the skillet, and cook for one additional minute.
Reduce the heat to medium-low, and stir the veggies and garlic occassionally while the heat fully reduces, for at least 1 ½ minutes but up to 2 minutes. (This is an extremely important step, because if you don’t let the heat reduce the butter will brown, drastically changing the flavor of the finished Cajun shrimp scampi.)
Add the stick of butter to the skillet, and let melt completely.
Pour the chicken broth, lemon juice, and chopped parsley into the pan, and stir until well combined.
Stir the seasoned shrimp into the skillet.
Cover the skillet partially, and cook for an additional 7 to 10 minutes, stirring often, or until the shrimp are opaque, curl into a C shape, and a digital thermometer inserted into them reads at least 145 degrees Fahrenheit.
Remove the skillet from the heat. If serving with cooked pasta, stir it into the pan and let it fully incorporate into the sauce.
Transfer to bowls or plates, and top with Parmesan.

If using frozen shrimp, extend the cooking time by 2 to 3 minutes, then temp them with your digital meat thermometer, making sure that they reach at least 145 degrees Fahrenheit.
Store the leftovers in an airtight container in the refrigerator for up to three days. Do not freeze, though, as the thawed scampi will likely lose much of its flavor and intended texture.
21/25-count fresh shrimp are best for this recipe as they are ready at the same time as the sauce.
Do the prep work, including chopping the herbs and veggies, and zesting and juicing the lemon, the night before to shave almost half of the stated recipe time.
For the best taste and texture, use freshly squeezed lemon juice, as bottled juice will likely yield a completely different flavor.
If you don’t have any fresh or jarred minced garlic on hand, you can add 2 teaspoons of garlic powder to the shrimp seasoning.
