Sheet-Pan Lemon Piccata Cod with Blistered Green Beans and Crispy Smashed Potatoes
Let us be honest for a second. Traditional chicken or fish piccata is delicious, but standing over a splattering skillet on a Tuesday night while trying to keep delicate fish from breaking apart? Hard pass. I created this sheet-pan version out of sheer weeknight exhaustion when I was craving those exact bright, buttery, caper-heavy flavors. I remember making it for the first time after a brutal day of recipe testing, staring into my fridge, and realizing I had cod, a bag of baby potatoes, and a lonely lemon. Roasting the fish right alongside smashed potatoes and green beans completely changed the game. The cod stays meaty and flaky, the potatoes get impossibly crispy, and everything gets drenched in a warm, silky garlic-butter sauce right on the pan. Yes, you can totally use frozen cod just make sure to thaw and pat it dry first. And if capers are not your thing? Swap them out for chopped green olives or just double down on the lemon. This is real food, zero stress, and only one pan to wash. Exactly how a Tuesday night dinner should be.

Timeline
Ingredients
- 1.5 lbs wild-caught cod fillets(4 center-cut fillets, patted thoroughly dry)
- 1 lb baby Yukon Gold potatoes(washed)
- 12 oz fresh green beans(trimmed)
- 3 tbsp olive oil(divided)
- 1.25 tsp kosher salt(divided)
- 0.5 tsp freshly cracked black pepper(divided)
- 0.5 tsp garlic powder
- 3 tbsp unsalted butter(chilled and cut into small cubes)
- 2 tbsp capers(drained)
- 1 lemon(thinly sliced into rounds, seeds removed)
- 0.25 cup fresh flat-leaf parsley(roughly chopped)
Instructions
- 1
Preheat your oven to 425°F (220°C). Place 1 lb baby Yukon Gold potatoes in a microwave-safe bowl with a splash of water, cover loosely with a plate, and microwave on high for 4 to 5 minutes until just fork-tender.
5 min
Tip: Pre-steaming in the microwave is my ultimate weeknight cheat code—it shaves 20 minutes off roasting time.

Transfer the par-cooked potatoes to an extra-large rimmed sheet pan. Use the flat bottom of a drinking glass or coffee mug to firmly smash each potato to about 1/2-inch thickness. Add 12 oz fresh green beans around the potatoes. Drizzle everything with 2 tbsp olive oil and season with 0.75 tsp kosher salt, 0.25 tsp freshly cracked black pepper, and 0.5 tsp garlic powder. Toss the green beans and turn the potatoes to coat, then spread into a single layer.
5 min
Tip: Don't smash the potatoes so hard that they disintegrate into mashed potatoes; you want them flattened but still mostly in one piece.
- 3
Slide the baking sheet into the oven and roast the potatoes and green beans for 8 minutes to get a head start on caramelizing.
8 min
Tip: Roasting the veg first ensures the potatoes turn crispy and the beans blister without overcooking our delicate cod.
- 4
While the vegetables start roasting, pat 1.5 lbs wild-caught cod fillets completely dry with paper towels. Rub both sides with 1 tbsp olive oil and season with the remaining 0.5 tsp kosher salt and 0.25 tsp freshly cracked black pepper.
3 min
Tip: Dry fish is the golden rule for sheet-pan seafood. If moisture sits on the surface, the fish steams instead of roasting.
- 5
Carefully remove the hot sheet pan from the oven. Push the vegetables toward the outer edges to create four open wells in the middle. Place the seasoned 1.5 lbs wild-caught cod fillets in the wells. Top each fillet with overlapping slices of 1 lemon, scatter 2 tbsp capers across the fish and vegetables, and dot 3 tbsp unsalted butter over the fish fillets.
2 min
Tip: Putting cold butter right on the fish lets it slowly melt over the fillets while they cook, basting them in rich pan juices.
- 6
Return the sheet pan to the oven and roast for 10 to 12 minutes, until the cod is opaque throughout and flakes easily with a fork (internal temperature of 140°F/60°C).
11 min
Tip: Cod cooks fast! Keep an eye on it around the 10-minute mark so it stays juicy and flaky.
- 7
Remove from the oven, sprinkle the whole pan with 0.25 cup fresh flat-leaf parsley, and spoon the melted lemon-caper pan juices right over the fillets before serving immediately.
2 min
Tip: Take the sheet pan straight to the table with a trivet—it looks gorgeous and saves dishes.
Chef's Notes
Classic piccata is traditionally dredged in flour and sautéed in a skillet, but delicate white fish like wild cod loves to stick and break when flipped. Cooking it high and fast on a sheet pan gives you identical savory, buttery, lemony goodness with zero sticking drama. If you can't find fresh green beans, thick asparagus spears work just as well with the exact same timing.

Delicious doesn't have to be difficult
I spent a decade in restaurant kitchens before my daughter was born and I realized I needed a different relationship with food. The 16-hour days had to end, but my love of cooking didn't. Now I'm obsessed with the puzzle of making genuinely good food achievable on a Tuesday night. No weird ingredients, no 47-step processes—just smart techniques and bold flavors that come together fast. Because life is too short for boring weeknight dinners.
