Start by gathering all your ingredients. Make sure your shrimp are peeled and deveined, and mince the garlic finely. This preparation will streamline your cooking process.
In a skillet over medium heat, add 1 tablespoon of olive oil. Allow it to heat for about a minute, ensuring it shimmers but does not smoke.
Once the oil is hot, add the minced garlic to the skillet. Sauté for about 30 seconds, or until fragrant. Be careful not to burn the garlic, as burnt garlic can become bitter.
In a bowl, combine the shrimp with the ground cumin, chili powder, onion powder (if using), and kosher salt. Toss the shrimp until they are evenly coated in the spices.
Add the seasoned shrimp to the skillet in a single layer. Cook for about 2-3 minutes on one side until they turn pink and opaque. Flip the shrimp and cook for an additional 2-3 minutes until fully cooked through.
Once the shrimp are cooked, remove the skillet from heat. If desired, squeeze fresh lime juice over the shrimp for an extra burst of flavor.
Serve the All-Purpose Spicy Shrimp Skillet immediately, perhaps alongside some rice, quinoa, or a fresh salad. Enjoy the delightful combination of spices and perfectly cooked shrimp.
