Step-by-Step Guided Instructions

FLUFF-FREE GUIDED STEPS
1Season the Shrimp

Pat 1.5 lbs large shrimp (peeled and deveined) completely dry with paper towels. In a small bowl, mix 1 tsp smoked paprika, 1/2 tsp garlic powder, 1/2 tsp onion powder, 1/4 tsp cayenne pepper, 1/4 tsp dried oregano, 1/4 tsp dried thyme, 1/2 tsp salt, and 1/4 tsp black pepper. Toss the shrimp in the spice mixture until evenly coated.

💡 Dad Pro Tip:

Dry shrimp is critical. Any moisture on the surface will steam instead of sear, and you will not get that blackened crust.

2Heat the Skillet

Place a 12-inch cast iron skillet over high heat for 3 minutes until it is smoking hot. Add 2 tbsp butter and let it foam and just start to brown.

💡 Dad Pro Tip:

Cast iron holds heat better than any other pan, which is why it is perfect for blackening. The spices char on contact with the superheated surface.

3Sear the Shrimp

Add the seasoned shrimp in a single layer, working in batches if necessary. Sear for 2 minutes without moving until the bottom is deeply charred. Flip and cook 2 more minutes until the shrimp are opaque and curled into a C-shape. Squeeze half a lemon over the shrimp in the pan.

💡 Dad Pro Tip:

Shrimp that curl into a tight O are overcooked. Pull them when they form a loose C-shape for perfect texture.

Dad Pro Tip

Four minutes total cook time for restaurant-quality blackened shrimp. The cast iron does all the work. Just make sure you open a window because that Cajun smoke will set off every alarm in the house.

👶 Kid & Toddler Adjustment:

Cut the cayenne pepper in half or skip it entirely for sensitive palates. The smoky paprika flavor is still delicious without the heat.

Serve With & Reheating
Suggested Sides:
  • Creamy grits
  • Rice pilaf
  • Caesar salad
🔥 Reheat Method (Restore Crunch):

Blackened shrimp are best fresh. If you must reheat, warm in a skillet over medium heat for 1 minute per side. Do not microwave.
