Camarones al Ajillo (Shrimp in Garlic and Guajillo Sauce) Recipe
Introduction
Camarones al Ajillo is a vibrant Mexican dish featuring succulent shrimp cooked in a fragrant garlic and guajillo chile sauce. This recipe delivers a perfect balance of smoky, tangy, and buttery flavors that is simple enough for a weeknight meal yet impressive for guests.

Ingredients
- 2 pounds large or extra-large shrimp, peeled and deveined, tails kept on
- Salt and black pepper, to taste
- 1/4 cup avocado or vegetable oil
- 3 large garlic cloves, minced
- 2 to 3 large dried guajillo chiles, stemmed and seeded, thinly sliced crosswise (about ¼ cup)
- 2 tablespoons unsalted butter
- 1/4 cup fresh lime juice (from 2 to 3 limes)
- Saltines or cooked rice, for serving (optional)
Instructions
- Step 1: Season the shrimp generously with salt and plenty of black pepper.
- Step 2: Heat a large deep skillet over medium-low heat. Add the oil and minced garlic and cook, stirring frequently with a wooden spoon, until the garlic turns light golden brown, about 4 to 6 minutes.
- Step 3: Add the sliced guajillo chiles and cook for about 1 minute, until the oil takes on a light ruby red color and the chiles become pliable.
- Step 4: Arrange the shrimp in a single layer in the skillet. Increase the heat to medium and cook undisturbed for 2 minutes to develop a sear.
- Step 5: Stir the shrimp and continue cooking until they start to curl and turn opaque, about 4 to 6 minutes more.
- Step 6: Add the butter and fresh lime juice, stirring until the butter melts and coats the shrimp evenly, about 2 minutes. Turn off the heat and taste, then add more salt if desired.
- Step 7: Serve immediately with saltines or cooked rice on the side if you like.
Tips & Variations
- Use avocado oil for a neutral flavor and higher smoke point, but vegetable oil works just as well.
- If guajillo chiles are hard to find, substitute with ancho or pasilla chiles for a similar smoky flavor.
- Adding a pinch of smoked paprika can enhance the smoky notes if desired.
- Serve with warm tortillas instead of rice for a traditional touch.
Storage
Store leftover shrimp in an airtight container in the refrigerator for up to 2 days. Reheat gently in a skillet over low heat to prevent overcooking and maintain tenderness. This dish is best enjoyed fresh but can be refreshed with a squeeze of lime juice when reheating.
