Ingredients

Instructions

  1. Step 1: Peel and quarter 4 medium russet potatoes (about 2 lbs), place in a large pot, cover with cold water, add 1 tsp salt, and bring to a boil over high heat. Boil for 15-20 minutes until fork-tender.
  2. Step 2: While potatoes cook, mix 2 tbsp Cajun spice mix, 1 tsp paprika, 1 tsp garlic powder, 1 tsp onion powder, 1/2 tsp cayenne pepper, 1 tsp salt, and 1/2 tsp black pepper in a small bowl. Pat dry 4 catfish fillets (6 oz each) and coat evenly with the spice blend.
  3. Step 3: Heat 3 tbsp olive oil in a large cast-iron skillet over medium-high heat until shimmering. Add the catfish fillets and cook for 4 minutes on each side until blackened and cooked through with a crisp crust.
  4. Step 4: Drain cooked potatoes and mash with 4 tbsp butter, 1/2 cup whole milk, and 3 minced garlic cloves until smooth and creamy. Season with salt to taste.
  5. Step 5: Plate the blackened catfish alongside a generous scoop of garlic mashed potatoes and garnish with 2 tbsp chopped fresh parsley for a fresh finish.
