Pat the shrimp dry. Moisture is the enemy of sear. Lay shrimp on paper towels and pat thoroughly so they cook quickly and brown a bit.
Season the shrimp. Toss with salt, pepper, garlic powder, and smoked paprika.
Drizzle with oil and toss again to coat.
Make the blue cheese dip. In a bowl, mix sour cream, mayo, blue cheese, lemon juice, and garlic. Season with salt and pepper. Adjust thickness with a little water or cream until it’s scoopable but smooth.
Chill while you cook.
Prepare the Buffalo sauce. In a small saucepan over low heat, melt butter with hot sauce, vinegar, onion powder, and cayenne. Whisk until glossy. Keep warm on the lowest heat.
Sear the shrimp. Heat a large skillet over medium-high.
When hot, add the shrimp in a single layer. Cook 1–2 minutes per side until pink and just cooked through. Work in batches if needed to avoid crowding.
Toss in Buffalo sauce. Transfer cooked shrimp to a bowl and pour the warm sauce over.
Toss gently to coat. Taste and add a pinch of salt or extra hot sauce if you want more kick.
Serve. Plate the shrimp with a side of blue cheese dip, celery, and cucumbers. Garnish with chopped parsley or chives.
For a meal, serve over cauliflower rice or in lettuce cups.
