Begin by thawing the shrimp completely if frozen, then pat them dry thoroughly with paper towels. Ensure the shrimp are deveined, and remove the tails if desired for easier eating.
In a small bowl, mix together the seasoning blend: Italian seasoning, salt, black pepper, and paprika. This mixture will infuse the shrimp with layered, aromatic flavor.
Place the shrimp in a large mixing bowl and toss them with the seasoning blend, making sure each shrimp is evenly coated.
In a skillet set over medium heat, melt the butter along with the minced garlic. Stir frequently as the butter melts to avoid browning the garlic—you're aiming for gentle infusion, not caramelization.
Once the garlic becomes fragrant, add the seasoned shrimp to the skillet in a single layer. Cook for 2 to 3 minutes on each side, or until the shrimp turn opaque and slightly golden at the edges.
Remove the skillet from heat and immediately squeeze fresh lemon juice over the shrimp. Give everything a gentle stir to coat the shrimp in the lemony garlic butter sauce.
Serve warm, garnished with lemon wedges or fresh herbs if desired.
