These Latin-American inspired cast-iron jumbo shrimp are marinated in lemon juice, sazon, garlic, and shallots and cooked hot and fast on the grill. We leave the shells on these shrimp, adding a little extra flavor to the sauce during cooking. Plus, it’s fun to slurp up all that seasoned goodness. YUM!
Why Buy Extra-Jumbo Shrimp?
Extra-jumbo shrimp are large and probably your best bet for a satisfying meal. You will get 16/20 shrimp per pound or 4-5 shrimp per 3 ounce portion. This cast-iron jumbo shrimp recipe calls for 1 1/2 pounds, roughly between 24-28 shrimp, or enough shrimp to feed 4-6 people. If you cannot locate extra jumbo shrimp, use the next size down. You will end up with more shrimp, but they will be smaller, and the portions will still work for 4-6 people with 5-7 shrimp per person instead.
Fresh vs. Frozen Shrimp
Unless you live in an area guaranteed to sell freshly caught shrimp, plan on purchasing frozen shrimp instead. Most of the glorious looking shrimp you displayed at your local grocery store were pre-frozen before shipping and thawed. There is no way to determine how long this shrimp has been sitting around, so we recommend buying the frozen shrimp and defrosting them yourself. The best way to do this is by placing the bag of frozen shrimp in your refrigerator the night before. They will be perfectly thawed by the time dinner rolls around the next day. We do not recommend leaving them in your fridge for longer than 24 hours.
Ingredients:
- 1 1/2 pounds extra-jumbo shrimp (about 24-28 shrimp):
- Olive oil
- Cilantro: leaves and soft stems only
- Garlic
- Shallot
- Lemons
- Sazon This recipe calls for 1 tablespoon of our rub recipe, but we recommend starting with 2 teaspoons and working up from there. We have used 1 1/2-2 tablespoons of this rub on occasion. But, be aware that our homemade Sazon is a little different from commercial Sazon which contains MSG. This additive can make the shrimp too salty. Follow the brand’s seasoning recommendations for the right amount, and omit the salt listed below.
- Salt (optional)
- Cast-iron skillet: You’ll need a 12″ skillet for this jumbo shrimp recipe.
Marinating the Shrimp
- Combine lemon juice with olive oil, garlic, shallot, sazon, and salt.
- To devein the shrimp, make a slit down the rounded back portion of the shell. Remove the dark brown vein. Leave the shell intact.
- Rinse the shrimp clean under cold water. Repeat the process with the remaining shrimp.
- Blot the shrimp dry with paper towels.
- Place shrimp in a resealable plastic bag. Pour half of the marinade over the top, and toss to coat with a pair of tongs. Seal the bag and place shrimp in the refrigerator for 20-30 minutes—Reserve the other half of the marinade to make a delicious sauce for the cast-iron jumbo shrimp.
Making Cast-Iron Jumbo Shrimp
- Preheat your grill for medium-high heat or 400 degrees F.
- Once the grill comes up to temperature, place your cast-iron pan on the grill to heat up for 5 minutes or until it emits a light wisp of smoke.

- Remove shrimp from the bag and add them to the pan. Discard the remaining marinade in the bag.
- Cook for 1 minute per side.
- Add reserved marinade to the pan. It will bubble, cook down quickly, and add extra flavor to the cast-iron jumbo shrimp.
- Turn the shrimp once more, and remove the pan from the grill.
- The shrimp is done once the flesh and shells turn pink and are firm (not excessively firm) to the touch.
- Serve cast-iron jumbo shrimp in the pan, or transfer to a to a serving dish. Garnish with chopped cilantro and lemon slices. See below for details.
- Optional step: Cut a lemon into 3-4 thick slices, and place them on the grill while the shrimp are cooking. Get a nice golden brown char on both sides, and serve the sliced lemon with the shrimp.
Stovetop Method

How to Store Leftover Cooked Shrimp:
