Succulent shrimp are bathed in a luxurious, golden pool of extra virgin olive oil infused with a mountain of toasted garlic and a gentle hum of chili heat. This low-carb masterpiece proves that you don't need bread to enjoy bold, sophisticated Mediterranean flavors.

🥗 Ingredients

The Seafood

  • 1.5 pounds Large Shrimp (peeled and deveined, tails left on for presentation)
  • 1/4 teaspoon Baking Soda (tossed with shrimp to ensure a crisp, snappy texture)
  • 1/2 teaspoon Kosher Salt

The Aromatics

  • 3/4 cup Extra Virgin Olive Oil (use high-quality Spanish oil if possible)
  • 12 pieces Garlic Cloves (thinly sliced into chips)
  • 2 pieces Dried Guajillo or Arbol Chili (sliced into rings, seeds removed for milder heat)
  • 1/2 teaspoon Red Pepper Flakes (optional, for extra kick)

The Finishers

  • 2 tablespoons Dry Sherry (Fino or Manzanilla) (adds depth; can substitute with lemon juice for keto)
  • 1/2 teaspoon Smoked Paprika (Pimentón de la Vera) (sweet variety)
  • 1/4 cup Fresh Parsley (finely chopped)
  • 1/2 piece Lemon (juiced)
  • 1/4 teaspoon Black Pepper (freshly cracked)

👨‍🍳 Instructions

  1. 1

    In a medium bowl, toss the cleaned shrimp with 1/2 teaspoon of kosher salt and 1/4 teaspoon of baking soda. Let them rest in the refrigerator for 15 minutes; this secret step ensures the shrimp stay plump and 'snap' when bitten.

  2. 2

    While the shrimp rest, slice the garlic cloves into very thin, uniform chips. Uniformity is key so they all brown at the same rate without burning.

  3. 3

    In a large, heavy-bottomed skillet or a traditional clay 'cazuela,' add the extra virgin olive oil and the sliced garlic.

  4. 4

    Turn the heat to medium-low. Cold-starting the garlic in the oil allows the flavor to infuse deeply without the garlic becoming bitter.

  5. 5

    Cook the garlic slowly, stirring frequently, for about 5-7 minutes until the slices turn a pale golden blonde. Do not let them turn dark brown.

  6. 6

    Add the sliced dried chilies and red pepper flakes to the oil. Sizzle for 1 minute until the oil takes on a slightly reddish hue and smells toasted.

  7. 7

    Increase the heat to medium-high. Once the oil begins to shimmer, add the shrimp in a single, even layer.

  8. 8

    Sear the shrimp for about 1-2 minutes per side. They should turn pink and opaque but remain slightly undercooked in the very center.

  9. 9

    Pour in the dry sherry (or lemon juice). It will bubble and steam vigorously; use a wooden spoon to scrape up any flavorful bits from the bottom of the pan.

  10. 10

    Sprinkle the smoked paprika over the shrimp. Stir gently to coat every shrimp in the vibrant red oil.

  11. 11

    Remove the pan from the heat immediately. The residual heat of the oil will finish cooking the shrimp to perfection without making them rubbery.

  12. 12

    Stir in the fresh chopped parsley and a squeeze of fresh lemon juice to brighten the fats.

  13. 13

    Season with freshly cracked black pepper and a pinch more salt if desired.

  14. 14

    Serve immediately while the oil is still sizzling, ideally straight from the pan.

💡 Chef's Tips

Always use the best olive oil you can afford, as it serves as the sauce for the dish. Avoid pre-minced garlic in a jar; the fresh-sliced chips are essential for the texture and sweet flavor. Don't overcook the shrimp; they are done the moment they form a 'C' shape. If they form an 'O', they are overdone. If you aren't strictly keto, use the leftover garlic oil to dip crusty bread; for keto, it's delicious drizzled over roasted cauliflower. If using frozen shrimp, ensure they are completely thawed and patted extremely dry with paper towels before seasoning.

🍽️ Serving Suggestions

Pair with a chilled glass of Albarino or a dry Manzanilla Sherry. Serve alongside a crisp green salad with a simple lemon-shallot vinaigrette. Provide keto-friendly almond flour crackers or toasted keto bread to soak up the garlic oil. Accompany with a side of roasted asparagus or sautéed zucchini noodles. Serve as part of a larger tapas spread with olives, Manchego cheese, and Marcona almonds.
