Full Ingredients

Parmesan–Panko Tilapia

• 4 tilapia fillets (5–6 oz each), patted very dry
• 3/4 tsp kosher salt, divided (1/4 tsp for fish, 1/2 tsp for beans)
• 1/2 tsp freshly ground black pepper
• 2 tbsp mayonnaise
• 1 tsp Dijon mustard
• 1 tsp fresh lemon juice
• 2/3 cup panko breadcrumbs
• 1/3 cup finely grated Parmesan cheese
• 1 tsp finely grated lemon zest
• 1/2 tsp garlic powder
• 2 tbsp unsalted butter, melted
• 1 tbsp olive oil (in crumb mixture) + more for pans
• 2 tbsp chopped fresh parsley (optional garnish)
• Lemon wedges, for serving

Roasted Green Beans

• 1 lb (450 g) green beans, trimmed
• 1 tbsp olive oil
• 1/4 tsp freshly ground black pepper
• Pinch red pepper flakes (optional)
• 1 tsp lemon juice, to finish

Quick Tartar Sauce

• 1/2 cup mayonnaise
• 2 tbsp finely chopped dill pickles or dill relish
• 1 tbsp capers, rinsed and chopped (optional)
• 1 tsp Dijon mustard
• 1 tbsp fresh lemon juice
• 1 tbsp finely chopped fresh dill or parsley
• Pinch kosher salt and black pepper, to taste

Step-by-Step Instructions

Step 1: Heat the oven and prepare pans

Preheat the oven to 450°F (232°C) with racks in the upper and lower thirds. Line two rimmed sheet pans with parchment or foil and lightly oil the surfaces. A hot oven and lined pans help the panko brown and keep cleanup easy.

Step 2: Stir together the tartar sauce

In a small bowl, combine the mayonnaise, chopped pickles, capers (if using), Dijon, lemon juice, dill or parsley, and a pinch of salt and pepper. Taste and adjust seasoning with a touch more lemon or salt. Cover and refrigerate while you cook to let the flavors mingle.

Step 3: Start the green beans

Toss the trimmed green beans with 1 tbsp olive oil, 1/2 tsp kosher salt, 1/4 tsp black pepper, and a pinch of red pepper flakes (optional). Spread in a single layer on one prepared pan. Roast on the lower rack for 6–7 minutes while you prepare the fish.

Step 4: Make the lemon–Parmesan crumb

In a medium bowl, mix the panko, Parmesan, lemon zest, garlic powder, melted butter, and 1 tbsp olive oil until evenly moistened and sandy. This fat-to-crumb ratio ensures a deeply golden, crunchy topping.

Step 5: Season and crust the tilapia

Pat the tilapia very dry with paper towels. Season the fillets lightly with 1/4 tsp kosher salt and a few grinds of pepper. In a small bowl, stir the binder: mayonnaise, Dijon, and lemon juice. Place the fillets on the second prepared pan. Brush only the tops with the binder, then divide and firmly press the panko–Parmesan mixture onto the tops to form an even crust from edge to edge.

Step 6: Bake the fish and finish the beans

Place the tilapia on the upper rack. Bake 10–12 minutes, until the crust is golden and the fish flakes easily with a fork and reaches 145°F (63°C) in the thickest part. The green beans should take 14–16 minutes total; toss with 1 tsp lemon juice when they come out. If you want extra color on the crumbs, broil the fish for 30–60 seconds at the end—watch closely.

Step 7: Plate and serve

Transfer the tilapia to plates, add a generous spoonful of tartar sauce, and place the roasted green beans alongside. Garnish the fish with chopped parsley and serve with lemon wedges for squeezing. A tiny pinch of flaky salt on the crust right before serving makes the flavors pop.

Pro Tips

• Dry fish equals crisp crust: blot thoroughly so the crumb adheres and browns instead of steaming.
• Press the crumbs on firmly and all the way to the edges to prevent bare spots and ensure even browning.
• Use finely grated (not shredded) Parmesan so it blends and melts into the panko.
• For even more crunch, lightly toast panko in a dry skillet for 2–3 minutes before mixing with butter and oil.
• Pull the fish at 140–145°F; it will continue to cook briefly from carryover heat and stay moist.

Variations

• Different fish: Swap tilapia for cod, haddock, catfish, or swai; adjust time slightly for thicker fillets.
• Air fryer: 400°F (204°C), 8–10 minutes for 5–6 oz fillets; check at 8 minutes. Green beans air-fry 6–8 minutes, shaking once.
• Gluten-free: Use gluten-free panko or crushed rice crackers/cornflakes; the rest of the recipe is naturally gluten-free.

Storage & Make-Ahead

Leftover tilapia and green beans keep in an airtight container for up to 2 days; reheat on a sheet pan at 350°F (177°C) for 8–10 minutes to re-crisp. Tartar sauce can be made 3 days ahead and refrigerated. The crumb mixture can be mixed 1 day ahead and refrigerated; bring to room temp before using. Freezing is not recommended for best texture.
