Step-by-Step Instructions
Step 1: Prepare the Shrimp
Remove the shrimp vein using a bamboo skewer or similar tool. Peel off the shell and tail. Wash the shrimp in salt water (3% concentration) to remove dirt and firm the flesh. Rinse well with fresh water, then dry completely with paper towels to prevent oil splashing.

Step 2: Prepare the Vegetables
Wipe the mushrooms gently with paper towels to remove dirt. Do not wash them with water. Cut large mushrooms in half if needed. Remove the garlic core and chop finely. Tear the chili pepper in half and remove the seeds.

Step 3: Arrange in the Skillet
Add olive oil, salt, garlic, and chili pepper to a small skillet. Mix gently. Place shrimp and mushrooms into the oil so they are mostly covered. A smaller pan helps keep ingredients submerged.

Step 4: Cook Slowly
Heat the skillet over low heat for 10 to 15 minutes until shrimp are cooked through. Do not rush. Finish with black pepper and chopped parsley. Serve warm.

Secrets to Success and Expert Tips
These simple but important tips will help you make flavorful, tender, and perfectly balanced Shrimp and Mushroom Ajillo every time:
-
♥
Dry the shrimp completely
Removing all surface moisture prevents oil splatter and helps the shrimp cook gently without steaming. -
♥
Do not wash mushrooms with water
Wiping them clean keeps their aroma strong and prevents them from releasing excess moisture into the oil. -
♥
Start with cold oil and low heat
Letting the garlic and chili warm slowly releases flavor without burning and creates a smooth, fragrant oil. -
♥
Keep the ingredients mostly submerged
Using a small skillet allows shrimp and mushrooms to cook evenly and absorb the olive oil fully. -
♥
Avoid stirring too often
Gentle cooking keeps the shrimp tender and prevents garlic from breaking apart or turning bitter.
