Make Ahead Options

These Authentic Spanish Garlic Shrimp (Gambas al Ajillo) are fantastic for meal prep, allowing you to enjoy a taste of Spain with less stress during busy weeknights! You can prep the shrimp by marinating them in olive oil, minced garlic, and red chili flakes up to 24 hours ahead; simply refrigerate the marinated shrimp. This not only enhances their flavor but keeps them juicy and tender when cooked. When you’re ready to serve, just heat the olive oil in your skillet, add the shrimp, and follow the cooking instructions. They’ll taste just as delicious and vibrant, saving you time without sacrificing flavor for your family or guests.

Expert Tips for Authentic Spanish Garlic Shrimp

Choose fresh shrimp: Use the freshest shrimp possible for the best texture and flavor; frozen shrimp can be thawed but avoid those pre-cooked.
Slice garlic thinly: Thin garlic slices ensure even cooking and a perfect golden color without burning, which can turn the oil bitter.
Control the heat: Cook garlic over medium heat to release flavors gently; too hot will burn it and ruin the delicate balance of this Authentic Spanish Garlic Shrimp dish.
Adjust chili flakes: Add chili flakes gradually to suit your spice tolerance; too much can overpower the garlic’s rich aroma.
Serve immediately: Gambas al Ajillo is best enjoyed fresh off the stove, when shrimp are tender and the oil is fragrant for dipping crusty bread.
Use quality olive oil: A high-quality extra virgin olive oil dramatically elevates the dish’s authenticity and depth of flavor.

How to Store and Freeze Authentic Spanish Garlic Shrimp

Fridge: Store any leftovers in an airtight container for up to 3 days to maintain freshness and flavor. Reheat gently in a pan over low heat to avoid overcooking.

Freezer: For longer storage, freeze the shrimp in a single layer on a baking sheet before transferring them to a freezer-safe bag. They can last up to 2 months frozen.

Reheating: When ready to enjoy, thaw shrimp overnight in the fridge, then reheat in a skillet over medium heat until warmed through, ensuring they remain juicy.

Serving Tip: Serve freshly made garlic shrimp immediately for the best taste; leftovers can still be delightful but may lose some of their vibrancy.

Authentic Spanish Garlic Shrimp (Gambas al Ajillo) Recipe FAQs

How do I know if my shrimp is fresh enough for Authentic Spanish Garlic Shrimp?
Look for shrimp that smell like the ocean—not fishy—and have firm, translucent flesh. Fresh shrimp should not have dark spots all over or a slimy texture. If you’re using frozen, choose high-quality, peeled, and deveined shrimp and thaw them in the fridge overnight for best results.

What’s the best way to store leftover Authentic Spanish Garlic Shrimp?
Store any leftovers in an airtight container in the refrigerator for up to 3 days. Keep it chilled promptly after serving, and when reheating, gently warm in a skillet over low heat rather than the microwave to preserve the delicate texture and avoid overcooking.

Can I freeze Authentic Spanish Garlic Shrimp? If so, how?
Absolutely! Spread the cooked shrimp in a single layer on a baking sheet and freeze until solid (about 1–2 hours). Then transfer the shrimp to a freezer-safe bag, removing excess air to prevent freezer burn. They’ll keep well for up to 2 months. When ready to eat, thaw overnight in the refrigerator and reheat gently in a pan for juicy, flavorful shrimp.

What should I do if my garlic burns while cooking?
Burnt garlic can turn the oil bitter and spoil the dish’s delicate balance. If this happens, I recommend starting over with fresh olive oil and garlic. To prevent burning, keep the heat medium or medium-low and watch the garlic carefully—it should turn a light golden, not dark brown. Stir frequently to cook evenly.

Is Authentic Spanish Garlic Shrimp safe for pets or people with allergies?
This recipe contains shellfish and garlic, both of which can be harmful to pets like dogs or cats, so keep it out of their reach. For allergy-conscious guests, always ask ahead and consider substituting shrimp with a seafood-free alternative or simply enjoy it yourself. The garlicky olive oil can also be used as a dip with other appetizers if shrimp aren’t an option.
