Ingredients
1½ lb Yukon gold potatoes, medium
Kosher salt
Fresh black pepper
2 tsp Fresh lemon zest
5 tbsp Olive oil
1 c Fresh flat-leaf parsley
½ c Large pitted green olives
¼ c Unsalted roasted almonds
2 tbsp Fresh lemon juice
1 Garlic clove, small
¼ tsp Crushed red pepper (optional)
4 piece Skinless white fish fillets, such as cod
Directions
Scrub the Yukon gold potatoes and cut them into evenly sized chunks. Place in a large pot of cold water, add a pinch of kosher salt, and bring to a boil. Simmer for 12–15 minutes until the potatoes are very tender and easily pierced with a fork.
While the potatoes cook, prepare the olive relish. Finely chop the fresh flat-leaf parsley, pitted green olives, and roasted almonds. Mince the small garlic clove.
In a small bowl, combine the chopped parsley, olives, almonds, minced garlic, fresh lemon juice, and ½ to 1 tablespoon of olive oil. Season with a pinch of kosher salt, black pepper, and crushed red pepper if desired. Set aside.
Pat the white fish fillets dry with paper towels and season both sides generously with kosher salt and fresh black pepper.
Heat 2 tablespoons of olive oil in a large skillet over medium-high heat. Once shimmering, carefully place the fish fillets in the pan. Sear for 4–5 minutes on the first side without moving them, until golden and crispy. Gently flip and cook the other side for 3–4 minutes until the fish is opaque throughout and flakes easily when tested with a fork, reaching an internal temperature of 145°F (63°C).
When the potatoes are tender, drain them well. Return to the pot and mash until smooth. Fold in 2 tablespoons of olive oil, the fresh lemon zest, and a pinch each of kosher salt and black pepper. Taste and adjust seasoning as needed.
Divide the lemon mashed potatoes among four serving plates. Top each portion with a seared white fish fillet and spoon the olive relish generously over each fillet. Serve immediately.
Comments
This is a solid weeknight dish that delivers on ingredient availability and speed. All components—potatoes, white fish, olives, lemon, garlic, and pantry staples—are stocked at Harris Teeter, Food Lion, Kroger, and Walmart year-round, with no special trips required. The 25-minute time is honest for searing fish and boiling potatoes, though you'll realistically need closer to 20-25 minutes if you're starting cold. Cost per serving lands around $4–5 depending on which white fish you choose (tilapia or cod at Walmart will anchor the low end), making it reasonable for a family of four. The relish adds sophistication without fuss, and leftovers reheat decently in the oven, though the fish texture won't be as perfect the next day. The main brake on a higher score is that it's a straightforward technique-heavy dish rather than a standout, and the relish's raw-olive edge doesn't have particular regional resonance for Charlotte.
