These garlic butter scallops are one of my favourite thing to put in front of my guests. They look like a proper production but actually only take about ten minutes to make. Really what’s happening is, the shells do all the visual work while you’ve just simply mashed butter with garlic and parsley and let the grill get on with it! They are great with persillade potatoes as they both use the same persillade base.

Where garlic butter scallops comes from
The French have been mad about coquilles Saint-Jacques for centuries, and the name carries a real story. They’re named for Saint James, Santiago in Spanish, Jacques in French, whose symbol was the scallop shell. Medieval pilgrims walking to Santiago de Compostela wore scallop shells on their hats as a badge of the journey, and over time the shell became so bound up with the saint that the scallop took his name.
The best scallops come from the cold waters off Brittany and Normandy, and the season runs from October through March, tightly controlled to protect stocks and keep the quality up. The moment it opens, coquilles Saint-Jacques appear on every menu. The French treat the arrival of scallop season with the same seriousness as the first asparagus of spring or the first Beaujolais Nouveau, and that seasonal specificity is part of what makes this dish worth doing properly. If you’re ever in Brittany or Normandy in season, order these in any decent brasserie!
Ingredients
- Scallops – Fresh, with the coral if possible, and never “soaked” or water-added. They should smell clean and of the sea. King scallops are ideal for grilling in the shell.
- Butter – Softened, and plenty of it. It’s half the dish, so use a good French one.
- Garlic – This is a garlic butter, so be be generous.
- Flat-leaf parsley – A large handful, chopped fine.
- Lemon – A wedge alongside, to cut the butter.
How to make garlic butter scallops
1. Make the persillade butter
Mash the softened butter with the garlic and most of the parsley, and season. That’s it. Make it as garlicky as you dare. You can do this days ahead and keep it in the fridge, which is what makes this such an easy thing to serve at a dinner party.
2. Prep the scallops
Pull off the tough little side muscle if it’s there, then rinse the scallops briefly and pat them completely dry, this matters, since wet scallops steam rather than caramelise. Nestle each into a shell and set them on a tray, on a bed of scrunched foil or parchment so the shells sit level and the butter doesn’t run out.
3. Butter and grill
Get the grill as hot as it goes. Put a generous spoonful (about a tablespoon) of persillade butter on each scallop, then grill for 7 to 8 minutes until the butter’s bubbling and the tops are golden and starting to caramelise. The scallops should be just opaque, since completely white and firm means overdone. Watch them like a hawk at the end: under a grill this hot, the gap between golden and burnt is about thirty seconds. Serve immediately, still bubbling.
Tools for this recipe
Check out my favorite kitchen essentials and cookware!
- Use scallop shells as the cooking vessel, which hold the butter around the scallop and look the part on the table!
- Use a baking tray with scrunched foil or parchment so the curved shells sit level and the butter stays put.
- Use a mixing bowl to mash the persillade butter together.
Tips for success
- Pat the scallops bone-dry: wet scallops steam and go pale instead of caramelising. Kitchen paper, properly, before they go in the shells.
- Be generous with the garlic: sweet scallops can take it, and a timid persillade just disappears. Load the butter properly.
- Don’t overcook them: just opaque is done. If they’re completely white and firm, they’ve gone. Scallops are unforgiving, so pull them the moment the butter’s bubbling and the tops are golden.
- Watch them under the grill: the difference between golden and burnt is about thirty seconds at 250°C. Don’t wander off.
- Level the shells: scallop shells wobble, so sit them on scrunched foil or parchment. Otherwise all that lovely garlic butter runs out onto the tray!
How to store it
- Garlic butter scallops are strictly a serve-now dish. They need to reach the table still bubbling, and once they cool the whole thing rather loses its magic. They also stiffen quickly, so I wouldn’t reheat leftovers, reheated scallop turns rubbery.
- The persillade butter is brilliantly make-ahead. It keeps in the fridge for up to 3 days, or roll it into a log in clingfilm and freeze it for a couple of months, then slice off discs straight onto the scallops.
- Raw scallops themselves don’t keep, buy them the day you’re cooking them and don’t hang about.

Variations
- Add breadcrumbs: a scatter of fine breadcrumbs over the butter before grilling, for a golden, crisp gratin top.
- Add a splash of wine or vermouth: a little dry white wine or Noilly Prat in the shell before grilling.
- Add lemon zest: a little zest in the persillade butter for extra brightness against the rich butter.
- Add cream: a spoonful of crème fraîche in each shell alongside the butter, closer to the classic gratinéed coquilles Saint-Jacques.
- Pan-sear them instead. No shells? Sear the scallops in a hot pan for a minute or so a side, then add the persillade butter and baste for 30 seconds. Different dish, same flavours.
- A pinch of chilli: not French, but a little heat in the butter is lovely with sweet scallops.
FAQ
How do I know when scallops are cooked?
They should be just opaque, no longer glassy in the middle but still tender. Completely white and firm means overcooked. Under a hot grill, 7 to 8 minutes with the butter bubbling and the tops golden is about right. Scallops go from perfect to rubbery very fast, so pull them early rather than late.
What are coquilles Saint-Jacques?
It’s simply French for scallops, named after Saint James (Jacques), whose symbol was the scallop shell, worn by medieval pilgrims to Santiago de Compostela. It also refers to the classic dish of scallops cooked and served in their shells, usually with butter or a creamy sauce, gratinéed on top.
Can I make garlic butter scallops ahead of time?
Make the persillade butter ahead (it keeps 3 days in the fridge, or freezes as a log for months) and have the scallops in their shells ready on a tray. Then grill to order, it takes 7 to 8 minutes. Don’t cook them in advance, as they need to reach the table bubbling and they toughen on reheating.
What can I use if I don’t have scallop shells?
Individual gratin dishes, small ovenproof ramekins, or even a single shallow baking dish all work. You lose the drama, but the flavour is identical. You can also buy scallop shells cheaply, and they last forever.
Why won’t my scallops caramelise?
Two usual culprits: they were wet, or they’d been “soaked.” Pat them thoroughly dry with kitchen paper before cooking, and avoid scallops labelled “soaked” or “water-added,” which have been pumped with water and will only ever steam and weep.

Ingredients
- 12 scallops with shells and coral if you can get them
- 100 gr unsalted butter
- 2 cloves garlic
- 40 gr flat-leaf parsley a large handful
- salt and black pepper
Equipment
Instructions
1. Make the persillade butter
- Mash the softened butter with the garlic and most of the parsley (save a little to garnish). Season with salt and pepper. Make it properly garlicky.
2. Prepare the scallops and preheat your grill
- Heat the grill to maximum (230–250°C). Keep the coral attached if it's there. Pull off the tough white side muscle. Rinse briefly and pat completely dry with kitchen paper. Nestle each scallop into a shell.
3. Arrange the scallops
- Set the shells on a baking tray on a bed of scrunched foil or parchment, so they sit level and the butter stays in.
4. Add the persillade butter
- Top each scallop with a generous spoonful (about 1 tbsp) of persillade butter, or a 3mm slice if it's chilled.
5. Grill
- Grill for 7 to 8 minutes, until the butter is bubbling and the tops are golden and just caramelising. The scallops should be just opaque. Watch closely in the last minutes.
6. Serve immediately
- Straight to the table, still bubbling, with lemon wedges and crusty bread for mopping.
Notes
- Try to get the scallops with the coral attached if you can, it adds sweetness and looks more impressive. Avoid anything labelled “soaked” or “water-added,” which basically means they’ve been pumped full of water to increase weight.
- Proper scallops should smell like the sea, not fishy.
- If you can’t find scallop shells (or can’t be bothered), individual gratin dishes or even a large shallow baking dish works fine too. You lose the drama, but the taste is identical.
- You can make the persillade butter up to 3 days ahead and keep it in the fridge. Just bring it to room temperature for 15 minutes before using, or slice it straight from the fridge if you’ve rolled it into a log.
