Sheet-Pan Shrimp Boil with Smoky Butter and Red Potatoes
Halved red potatoes roasted until the cut faces crisp, then green beans, red pepper, and shrimp tossed in smoky paprika butter and finished on the same tray with lemon.
Why You'll Love This Recipe
The pan it cooked in goes straight onto the table, with a stack of plates beside it and everyone reaching. A shrimp boil is usually a pot, a colander, and a table covered in newspaper, and the oven version gives you the same thing with browning where the boiling used to be, and one tray to wash. It takes about an hour, most of it hands off while the potatoes roast, and it is genuinely a good dinner for people who are not being careful about anything, which is the point. Nobody looks at a pan of shrimp and potatoes and thinks about protocols.
The seasoning is the part worth paying attention to. Every seafood boil blend on the shelf is built on celery salt, onion powder, and garlic powder, which is exactly the wrong list, so this butter gets built from scratch instead. Smoked paprika does the heavy work and gives you the color and the smell of something that spent time over a fire, cayenne brings the heat, dried oregano keeps it from tasting flat, and a good amount of black pepper does more than people expect. The butter is melted with the spices in it, not shaken over them dry, so it turns deep orange and coats everything it touches.
Order and timing are the whole method. Potatoes go in first, cut side down and left alone, for twenty-five minutes, which is what gives them a flat gold crust rather than a pale steamed surface. Green beans and pepper strips join for ten. The shrimp go on last, tossed in most of the butter, and need six to eight minutes and not a second more, because shrimp go from sweet and firm to rubbery in about the time it takes to answer the door. Lemon juice and parsley go over the hot tray at the end, and the pan spends the next ten minutes emptying.
Ingredients
- 1 1/2 lb large raw shrimp, peeled and deveined, tails on
- 1 1/2 lb baby red potatoes, halved
- 12 oz green beans, trimmed
- 1 large red bell pepper, cut into wide strips
- 6 tbsp butter
- 2 tbsp garlic-infused olive oil
- 1 tbsp smoked paprika
- 1 tsp dried oregano
- 1/2 tsp cayenne
- 1 1/2 tsp black pepper
- 3 tbsp fresh lemon juice, plus 2 lemons cut into wedges
- 1/3 cup chopped fresh parsley
- 2 tsp fine sea salt, divided
Instructions
- Heat the oven and start the potatoes: Heat the oven to 425°F (220°C). Toss the halved potatoes with the garlic-infused olive oil and 1 teaspoon of the salt, then arrange them cut side down on a large sheet pan with space between them. Roast 25 minutes, without turning them, until the flat faces are gold and crisp.
- Make the smoky butter: While the potatoes roast, melt the butter in a small saucepan over low heat. Take it off the burner and stir in the smoked paprika, oregano, cayenne, black pepper, and the remaining 1 teaspoon of salt. It will turn deep orange and smell strongly of smoke within a few seconds.
- Add the vegetables: Pat the green beans dry and toss them and the pepper strips with about a third of the butter. Push the potatoes to one side of the pan, add the vegetables in a single layer, and roast 10 minutes, until the beans blister at the tips and the peppers soften at the edges.
- Toss the shrimp: Pat the shrimp thoroughly dry, which matters more than any other prep step here, and toss them with half of the remaining butter until every one is coated. Wet shrimp steam rather than roast and never pick up color.
- Roast the shrimp: Scatter the shrimp across the tray, tucking them between the vegetables so they sit directly on the hot pan. Roast 6 to 8 minutes, until they turn pink and opaque and have just curled into a loose C shape. A tight spiral means they went a minute too far.
- Finish at the table: Pour the last of the butter over the hot tray, squeeze the lemon juice across everything, and scatter the parsley. Take the pan to the table on a board, put the lemon wedges beside it, and let everyone serve themselves.
Variations
- Add sausage: Slice a cooked pork sausage you tolerate and roast it with the potatoes for the last 10 minutes.
- Lemon pepper: Skip the smoked paprika and cayenne and use a full tablespoon of black pepper with the zest of both lemons in the butter.
- Herb butter: Stir 2 tablespoons of chopped dill or chives into the butter off the heat for a fresher, greener tray.
- Scallops: Swap half the shrimp for sea scallops, patted dry and added at the same time, and pull the tray when they turn opaque at the edges.
- Grill it: Cook everything in a foil packet on a covered grill at medium-high, adding the shrimp in the last 8 minutes.
Storage & Leftovers
Leftovers keep in a sealed container for up to 2 days, though shrimp are always best on the night. Store them mixed through the potatoes, not in a layer at the bottom, since the vegetables hold heat more gently when it comes time to warm everything up again.
Reheat in a skillet over medium heat with a small knob of butter, about 3 minutes, and add the shrimp only in the last minute so they warm through without cooking further. A microwave will turn a good shrimp rubbery in well under a minute, so it is worth the pan.
Do not freeze the finished tray, since thawed shrimp go soft and the potatoes turn mealy. What you can do ahead is roast the potatoes and mix the spiced butter up to a day early, then reheat the potatoes in a hot oven and carry on from the vegetable step.
Notes & Tips
- Cut side down and leave it: The flat gold face on a roasted potato only happens if it sits still on hot metal, so resist turning them at the halfway mark and let the pan do the work.
- Dry the shrimp properly: Surface water is the difference between roasted shrimp and steamed ones, so pat them hard with a towel before the butter goes anywhere near them.
- Build the butter yourself: Old Bay and every boil blend beside it start with celery salt, onion powder, and garlic powder, so mixing smoked paprika, oregano, cayenne, and pepper into melted butter puts you back in control of the whole tray.
- Watch the curl: A shrimp bent into a loose C is done and a shrimp curled into a tight O has gone too far, and it is a two-minute window, not a five-minute one.
- Use the biggest pan you own: Crowded food steams, and a tray with room around each piece is the single easiest way to get color on everything at once.
- What the others can add: Put out bread for mopping the butter, hot sauce, and a bowl of cocktail sauce for the rest of the household to spoon onto their own plates rather than over the tray.
Nutrition & Mindful Eating
- Shrimp, potatoes, and a tray of vegetables under one spiced butter is a complete dinner in a single pan. The shrimp bring the protein, the potatoes give it weight, and the beans and peppers keep the whole thing from eating heavy.
- Shrimp are sweet, firm, and quick-cooking, and they carry selenium and B12 in a form that comes with very little fat of their own, which is why the butter here is doing the richness rather than the seafood.
- Red potatoes roasted cut side down turn gold and faintly sweet at the flat faces, and cooking them with the skins on keeps both the potassium and the fiber that sit just under the surface.
- Green beans blistered at the tips and red pepper strips softened at the edges are where most of the vitamin C on the tray comes from, and roasting rather than boiling keeps more of it in the food.
- Smoked paprika melted into butter is what gives this its color and the smell of something cooked over a fire, and the lemon squeezed over the hot pan at the end is why a buttery tray still tastes fresh.
- As you eat, notice how the potatoes crackle at the cut face against the softness of the shrimp, and take the extra minute to squeeze another wedge of lemon over your plate before you start.
Frequently Asked Questions
Can I use frozen shrimp?
Yes, and most shrimp at the counter were frozen anyway. Thaw them in a colander under cold running water for about 5 minutes, then dry them very well on a towel. Any water left on the surface will steam them on the tray and keep them from browning.
What can I use in place of the green beans?
Broccoli florets, halved zucchini, or wide strips of red cabbage all roast in about the same ten minutes. Keep the pieces big so they do not overcook while the potatoes finish, and give everything room on the pan.
How spicy is this?
Warm rather than hot. Half a teaspoon of cayenne across four servings reads as a low background heat behind the smoked paprika. Take it to a full teaspoon if your table likes it hot, or leave it out and let people add their own at the end.
Does this fit a low-FODMAP dinner plan?
It does. Bottled seafood boil seasonings are built on celery salt, onion powder, and garlic powder, which is why the butter here is mixed from smoked paprika, oregano, cayenne, and pepper instead. Garlic-infused olive oil on the potatoes gives you the garlic note without the rest.
