Ingredients
For the fish
⅓ cup basil pesto, or another pesto of your choice
1 ½ tablespoons olive oil
1 lemon, plus lemon wedges to serve
1 bunch collard greens (about ½ pound), thick stems removed, leaves rolled crosswise and sliced into ½-inch-thick ribbons
1 (14-ounce) can cannellini beans, drained and liquid reserved
4 (5- to 7-ounce) white fish fillets (such as cod, haddock or hake)
½ teaspoon fine sea salt, plus more for seasoning
For the bread crumbs
⅓ cup panko bread crumbs
2 garlic cloves, grated or minced
1 ½ tablespoons olive oil
½ teaspoon fine sea salt
Preparation
- Step 1
Prepare the fish: Heat the oven to 400 degrees. Finely grate the zest of the lemon into a medium bowl (reserve the zested lemon). Add the pesto and olive oil and stir to combine.
- Step 2
To a large sheet pan, add the collard greens, drained beans, half the pesto mixture, ¼ cup reserved bean liquid, and salt. Cut the lemon in half and squeeze in 2 tablespoons of juice. Use your hands or two large spoons to combine and spread in an even layer.
- Step 3
Pat the fish fillets dry with paper towels. Season lightly with salt on all sides and use your hands to coat the fillets with the remaining pesto mixture. Arrange the fish fillets on top of the vegetable mixture.
- Step 4
Prepare the bread crumbs: In a small bowl, mix together the panko, garlic, olive oil and salt. Use your hands or a large tablespoon to coat the top of the fish fillets with the bread crumbs, pressing the crumbs down so they stick onto the fish.
- Step 5
Bake until the fish is cooked through and flakes easily with a fork, the greens are tender and the panko topping is golden, 12 to 15 minutes, depending on the thickness of your fish.
- Step 6
Serve immediately with lemon wedges.

We substituted broccolini for the collard greens, blanching the spears first so they would be tender after baking. Delicious!
Great blend of flavors and textures. Will certainly make again. Didn’t have collard greens so substituted with fresh spinach, which worked well.
Made this tonight as written, except before starting the recipe thinly sliced a few potatoes along with an onion. Tossed them in olive oil, salt and pepper and roasted for 15 minutes. Put the greens, beans and fish on top of the potatoes. And cooked as directed, delicious!
Delicious! I used Swiss chard. Don't throw away the stems! Cut them in bits of half an inch (or smaller) and add them to the mix – no waste.
After a few bites, hubby said, “Put this one in the rotation.” It was blessedly easy since I already had homemade pesto in the freezer. Used cod and Swiss chard. I ended up baking it for 17 minutes but otherwise stuck to the recipe. Sheet-pan cookery is not my forte but I’m slowly getting the hang of it.
Loved this dish; the flavors are terrific. But there is no way the collard greens were cooked in the time it took to bake the fish. They were dry or raw if they were under the fish. I would blanch the greens next time.
