Sheet Pan Scallops with Butternut Squash and Salsa Verde

Scallops have a reputation for being fussy, and most of that reputation comes from people trying to sear them in a pan that isn’t hot enough or crowded with too many at once. This recipe skips that problem entirely. The squash roasts on a sheet pan until it’s caramelized and soft, the scallops go in at the very end for a short blast of heat, and a bright, herby salsa verde gets spooned over the top right before serving. Total hands-on time is maybe 15 minutes.

What you get is a dinner that looks like it took real effort — golden squash, a sharp green sauce, scallops with a little color on top — but the actual cooking is almost entirely hands-off. This is a weeknight dinner that also happens to be good enough for company.

Why This Recipe Is Worth Making

Sheet pan dinners get a bad name because a lot of them turn into a pile of mushy vegetables and dry protein. This one avoids that by cooking the squash almost all the way through before the scallops ever touch the pan — so neither ingredient overcooks waiting on the other.

It’s also genuinely fast for how good it looks on a plate. Scallops cook in minutes, the squash can roast while you make the salsa verde, and there’s exactly one pan to clean. If you’ve been intimidated by cooking scallops at home, this is a low-risk way to get comfortable with them, since the margin for error here is a lot wider than a stovetop sear.

What You’ll Need

• 1.5 lbs (680g) large sea scallops, side muscle removed — dry-packed scallops are worth seeking out; wet-packed ones are treated with a preservative solution and will steam instead of browning
• 1 medium butternut squash (about 2 lbs / 900g), peeled and cut into 3/4-inch cubes
• 4 tablespoons olive oil, divided
• Salt and black pepper, to taste
• 1/2 teaspoon smoked paprika or regular paprika, for the squash
• 1 cup fresh parsley leaves, roughly chopped
• 1/2 cup fresh cilantro leaves (or extra parsley if you’d rather skip cilantro entirely)
• 1 small shallot, finely minced
• 1 clove garlic, minced
• 2 tablespoons capers, drained and roughly chopped
• 2 tablespoons red wine vinegar (or lemon juice, if you’d rather keep it simpler)
• Zest and juice of 1 lemon
• 1/3 cup extra-virgin olive oil, for the salsa verde

How to Make Sheet Pan Scallops with Butternut Squash and Salsa Verde

1. Preheat your oven to 425°F (220°C). Toss the squash cubes with 2 tablespoons olive oil, the smoked paprika, and a generous pinch of salt and pepper. Spread them in a single layer on a rimmed baking sheet — don’t crowd them, or they’ll steam instead of caramelizing. Roast for 20 to 25 minutes, flipping once halfway through, until the edges are browned and a fork slides in easily.
2. While the squash roasts, make the salsa verde. In a bowl, combine the parsley, cilantro, shallot, garlic, and capers. Add the red wine vinegar, lemon zest and juice, and the 1/3 cup olive oil. Stir well and season with salt and pepper. Taste it — it should be sharp and a little aggressive on its own, since it mellows once it’s spooned over the warm scallops and squash. Set aside.
3. Pat the scallops completely dry with paper towels. This step matters more than it sounds like it should — any surface moisture will stop them from browning, no matter how hot your oven or pan gets. Season both sides with salt and pepper.
4. Once the squash has 20 to 25 minutes in and is nearly tender, push it to one side of the pan (or move it to a plate if the pan feels crowded) and add the scallops in a single layer, drizzled with the remaining olive oil. Return the pan to the oven and roast for 6 to 8 minutes, until the scallops are opaque all the way through and firm to the touch — they’ll still give slightly in the center when done, not feel hard.
5. For a browned top instead of a plain roasted one, switch the oven to broil for the last 1 to 2 minutes of cooking. Watch closely — scallops go from lightly golden to overcooked in under a minute under a broiler.
6. Pull the pan out, spoon the salsa verde generously over the scallops and squash, and serve immediately, straight from the pan or divided onto plates.

Tips That Actually Make a Difference

Dry the scallops twice, not once. Pat them dry when you first take them out of the fridge, then let them sit on a paper towel while the squash finishes roasting, and pat them dry again right before they go in the oven. Scallops release moisture as they sit, and that second pass makes a real difference in how well they brown.

Cut the squash into uniform pieces. If some cubes are twice the size of others, you’ll end up with a mix of mushy and undercooked pieces in the same batch. Aim for pieces close to 3/4 inch on every side.

Make the salsa verde ahead if you can. It actually improves after 20 to 30 minutes as the flavors settle together, and it means one less thing to juggle when the scallops come out of the oven.

Mistakes to Watch Out For

Overcrowding the squash. If the cubes are touching or piled on top of each other, they’ll release steam and never develop that caramelized edge. Use two pans if one isn’t big enough — it’s worth the extra dish.

Overcooking the scallops. This is the single biggest risk in this recipe. Scallops go from perfectly tender to rubbery in a matter of minutes, and they keep cooking slightly after you pull them from the oven. Check them a minute or two early if you’re unsure — you can always put them back in, but you can’t undo overcooked scallops.

Skipping the dry step. Wet scallops steam. Steamed scallops don’t brown, and a pale, gray scallop is a disappointing scallop even if it’s cooked correctly. Take the extra minute with the paper towels.

Buying wet-packed scallops without realizing it. These are treated with a chemical solution that makes them retain water, and they will not brown no matter what you do. Ask your fishmonger for “dry-packed” or “diver” scallops specifically, or check the label for phosphates.

Easy Ways to Change It Up

• Swap the squash for sweet potato — cut into similar-sized cubes and roast on the same timeline; the flavor is sweeter and slightly less nutty than butternut.
• Add heat to the salsa verde — a finely minced fresh chile or a pinch of red pepper flakes stirred in gives the sauce a sharper edge that plays well against the sweetness of the squash.
• Use shrimp instead of scallops — large shrimp work on the same timeline and are more forgiving if you’re still building confidence with quick-cooking seafood.
• Make it dairy-free and gluten-free — it already is, as written, which makes it an easy one to serve to a mixed table without extra substitutions.

What to Serve It With

This dish is rich enough from the scallops and bright enough from the salsa verde that it doesn’t need much alongside it. A simple green salad with a sharp vinaigrette rounds it out well. If you want something more substantial, serve it over a bed of cooked farro or quinoa — both soak up the extra salsa verde and turn this into a full one-bowl meal.

Crusty bread on the side is never a bad call here either, mostly because you’ll want something to mop up the last bit of sauce on the pan.

Leftovers and Reheating

Scallops are genuinely best eaten the day you make them — reheating tends to push them past done into tough territory. If you do have leftovers, store the scallops, squash, and salsa verde separately in airtight containers in the fridge for up to 2 days.

Reheat the squash in a hot oven or skillet until warmed through. For the scallops, the gentlest option is to chop them and fold them cold into a salad or grain bowl rather than reheating them directly — you’ll get better texture that way than trying to warm them back up. The salsa verde needs no reheating at all; just bring it to room temperature and use it as is.

Final Thoughts

This is the kind of recipe worth keeping on hand for the nights you want something that feels a little special without actually asking much of you. The squash does most of the work in the oven, the salsa verde takes ten minutes with a knife and a bowl, and the scallops need only a few careful minutes of attention. Give it a try the next time you want dinner to look better than the effort it took to make it.
