Entrees

The skillet comes out of the oven still sputtering, and the smell of garlic and lemon hits the room before it hits the trivet. This lemon garlic shrimp gets there in 25 minutes: shrimp baked in a pool of extra-virgin olive oil with fresh lemon zest, lemon juice, garlic, and paprika, emerging golden and fragrant. Wonderful Seedless Lemons contribute both zest and juice. The zest perfumes the oil with essential citrus oils; the juice brightens the dish and keeps the shrimp tender. Because they're naturally seedless and Non-GMO Project Verified, there's nothing to fish out of the hot oil. Zest, squeeze, and go. California-grown, available November–June.

Difficulty: — The cast iron skillet does most of the work. The one technique worth knowing: turn the shrimp exactly once, halfway through baking, so both sides get that golden, bubbling edge.

Overview

Gambas al ajillo originates in the coastal fishing communities of Andalusia, where shrimp were abundant and olive oil was the cooking fat of everyday life. The oven adaptation works because cast iron distributes heat evenly, keeping the oil at a consistent temperature throughout the bake, and the citric acid in lemon juice gently denatures the shrimp proteins at a slightly lower temperature than heat alone, producing shrimp that are golden outside and just-cooked tender all the way through.

Because Wonderful Seedless Lemons are naturally seedless, you avoid the single most frustrating part of cooking citrus into a hot oil dish: seeds. Drop a lemon seed into 350°F olive oil and it sits there, invisible until someone bites into it. With seedless lemons, you zest directly over the bowl, squeeze directly into the skillet, and move on. There is no straining, no fishing with a fork, no second-guessing. The zest goes into the marinade; the juice goes in with it; and the skillet goes straight into the oven.

Wonderful Seedless Lemons are naturally seedless, Non-GMO Project Verified, and California-grown.

Ingredients

Shrimp:

1 lb. medium shrimp, peeled and deveined

Marinade:

½ cup extra-virgin olive oil
½ tablespoon Wonderful Seedless Lemon zest (from about one seedless lemon)
1 tablespoon Wonderful Seedless Lemon juice (from the same lemon)
2 cloves garlic, minced
½ teaspoon salt
¼ teaspoon paprika

To Serve:

1 tablespoon chopped fresh Italian parsley, for garnish
Red pepper flakes, for garnish- Toasted sliced baguette, for serving (optional)

Instructions

Prep the Lemons

Zest the seedless lemon first, before cutting it in half. Hold the lemon against a fine microplane or box grater and rotate until you have ½ tablespoon of bright yellow zest. Zesting before juicing gives you a firm surface to work against and extracts more of the fragrant essential oils from the peel. No straining needed. Wonderful Seedless Lemons deliver clean zest and clean juice with nothing to pick out.
Halve the lemon and squeeze 1 tablespoon of juice into a small bowl, catching any pulp with your hand if needed. Set the zest and juice aside.

Mix the Marinade

In a medium bowl, combine the shrimp, olive oil, lemon zest, lemon juice, minced garlic, salt, and paprika. Stir well until the shrimp are evenly coated and the spices are distributed throughout the oil. The marinade will look like a lot of olive oil. That is correct. It is the cooking medium, not just a coating, and it is what keeps the shrimp basted and golden throughout the bake.

Bake the Shrimp

Preheat the oven to 350°F. While the oven heats, let the marinating shrimp rest at room temperature, as this helps them cook evenly rather than going from cold to hot too quickly in the oven.
Transfer the shrimp and all of the marinade to a 6-inch cast iron skillet, arranging the shrimp in a single layer as much as possible. The skillet should be snug but not so crowded that the shrimp are stacked.
Bake for approximately 20 minutes, turning the shrimp once at the 10-minute mark. You are looking for shrimp that have turned pink and opaque throughout, with a golden color on the edges and the olive oil visibly bubbling around them. Shrimp go from done to overdone quickly, so check at 18 minutes if your oven runs hot. The shrimp are ready when they curl into a loose "C" shape. If they curl tightly into an "O," they have gone a minute too long.

Serve

Remove the skillet from the oven and let it rest for two minutes, as the oil will still be very hot. Garnish with chopped fresh Italian parsley and a pinch of red pepper flakes for color and a gentle bite. Bring the skillet directly to the table and serve with toasted baguette slices for soaking up the lemon-garlic olive oil. The oil at the bottom of the skillet is arguably the best part.

Optional Tips

Always zest before you juice. The lemon is easier to zest when it is still whole and firm. Once you cut it in half and squeeze, the remaining flesh is too soft to hold steady against a grater. Zesting first also means you get every bit of fragrant peel before any juice escapes.

Do not skip the paprika. A quarter teaspoon of paprika might seem like a background note, but it does two things: it adds a subtle warmth that reads as depth rather than spice, and it gives the olive oil a faint golden color that makes the finished dish look as good as it tastes. Smoked paprika works here if you want a slightly deeper, more complex flavor.

Let the shrimp come to room temperature before baking. Cold shrimp straight from the refrigerator take longer to cook through, which can mean overcooked outsides before the center sets. Five to 10 minutes at room temperature while the oven preheats is enough to close that gap.

The cast iron skillet is not optional. A standard baking dish or sheet pan will technically cook the shrimp, but cast iron retains heat so evenly that the oil stays at a consistent simmer rather than pooling in spots. That even heat is what produces the golden, bubbling finish on every piece. A 6-inch skillet is the right size for one pound of shrimp. Any larger and the oil spreads thin and can scorch.

Turn the shrimp once, not more. At the 10-minute mark, flip each shrimp with tongs or a spoon so the other side gets contact with the hot oil. Turning more frequently drops the oil temperature and prevents that caramelized edge from forming. One turn is all it takes.

Toast the baguette in the residual oven heat. After the shrimp come out, slide sliced baguette directly onto the oven rack for two to three minutes while the skillet rests. The bread goes from room temperature to lightly golden and crisp, and it is ready at exactly the right moment to meet the oil in the skillet.

The marinade is also a make-ahead tool. Combine the shrimp, olive oil, lemon zest, lemon juice, garlic, salt, and paprika up to two hours ahead and keep it covered in the refrigerator. When you are ready to cook, let it sit at room temperature for five to 10 minutes, then transfer to the skillet and bake as directed.

Adjust the heat with the red pepper flakes. The recipe calls for red pepper flakes as a garnish, which gives you control over the heat level at the table. If you want the heat baked in, add 1/4 teaspoon of red pepper flakes to the marinade before it goes into the oven.

Variations

Stovetop Gambas al Ajillo. Skip the oven entirely and cook the shrimp in the cast iron skillet over medium-high heat on the stovetop. Heat the olive oil first until shimmering, then add the garlic for 30 seconds before adding the shrimp. Cook two to three minutes per side until pink and golden. This version is slightly faster and produces a more pronounced sear, though the oven method gives you a little more control over the final texture.

Spicy Lemon Garlic Shrimp. Add 1/4 teaspoon of red pepper flakes directly to the marinade alongside the paprika, and finish with a second pinch as garnish. For more heat, add a small dried chile (like an árbol) to the skillet before it goes into the oven and remove it before serving. The citrus from the seedless lemons balances the heat cleanly, so the spice reads as bright rather than aggressive.

Lemon Garlic Shrimp Pasta. Cook 8 ounces of linguine or spaghetti until just shy of al dente and drain, reserving 1/2 cup of pasta water. After the shrimp come out of the oven, toss the pasta directly into the skillet with the shrimp and olive oil, adding a splash of pasta water to loosen the sauce. Finish with extra parsley and a squeeze of fresh seedless lemon juice. It becomes a full dinner with almost no additional effort.

Served as Tapas. Scale the recipe to two servings and bring the cast iron skillet to the table with a small basket of bread and a bowl of olives alongside. At a tapas spread, the skillet format is part of the experience: guests spear shrimp directly and use the bread to chase the oil. Pair it with a glass of chilled Albariño or fino sherry to keep the Spanish theme intact.

Herb Swap: Dill or Basil. Italian parsley is the traditional garnish, but fresh dill gives the dish a slightly Scandinavian inflection that works surprisingly well with shrimp and lemon. Fresh basil, added right before serving so the heat does not wilt it, pushes the flavor profile toward the Mediterranean coast of France. Either swap keeps the same marinade and bake time.

Lemon Garlic Shrimp Over Rice. Spoon the shrimp and all the olive oil from the skillet over a bowl of steamed white rice or orzo. The oil absorbs into the grain and becomes its own sauce. Add a few extra squeezes of seedless lemon juice over the finished bowl to bring the brightness back up after the rice absorbs some of the acidity.
