Dungeness Crab with Roasted Winter Vegetables and Baked Potatoes
Sweet Dungeness crab needs very little alongside it: deeply roasted winter vegetables, a crisp-skinned potato, and a little lemon. The broccoli’s charred edges and soft, sweet onions balance the delicate crab, while butter melts into the fluffy potato—a straightforward San Francisco winter dinner.

Gently Steamed Dungeness Crab
A short steam warms already-cooked crab without washing out its sweetness. Cracking the shells before serving makes the meal easier to eat while preserving the generous shell-on presentation.
Ingredients
- 2 large cooked Dungeness crabs, about 2 lb each before cleaning, cleaned and divided into body-and-leg sections
- 1 lemon, cut into wedges
- as needed water for steaming
Instructions
- Keep the cooked crab refrigerated while preparing the vegetables and potatoes. If necessary, remove the top shells, gills, and viscera, and divide each cleaned body into two sections with the legs attached.
- Lightly crack the claws and thick leg joints with a cracker or the back of a heavy knife, leaving the meat in its shell.
- Bring about 1 inch of water to a simmer beneath a steamer rack in a large covered pot. Keep the crab above the water.
- Add the crab, cover, and steam for 5–8 minutes, until the thick body sections are hot inside. Work in batches if needed; avoid prolonged steaming, which makes the meat stringy.
- Transfer to a platter, let excess water drain, and serve immediately with lemon wedges.
Notes
- Buy crab from a reputable seafood seller and ask for it cooked and cleaned. Cooking does not eliminate marine biotoxins, so follow local crab advisories.
- For chilled crab, skip steaming and keep refrigerated until serving.
Roasted Broccoli, Brussels Sprouts, and Onion
A hot oven and an uncrowded pan produce browned edges rather than steamed vegetables. Onion softens and sweetens among the brassicas, with lemon bringing the finished vegetables back into balance.
Ingredients
- 1 lb broccoli, cut into medium florets, tender stems peeled and sliced
- 12 oz Brussels sprouts, trimmed and halved
- 1 medium yellow onion, cut into 1/2-inch wedges
- 3 tbsp extra-virgin olive oil
- 3/4 tsp kosher salt, plus more to taste
- 1/4 tsp freshly ground black pepper
- 2 tsp fresh lemon juice
Instructions
- Heat the oven to 425°F. Dry the vegetables thoroughly so their surfaces brown readily.
- Toss the Brussels sprouts and onion with 1 1/2 tablespoons olive oil and half the salt and pepper. Spread on a large rimmed baking sheet, positioning the sprouts cut-side down.
- Roast for 10 minutes. Meanwhile, toss the broccoli with the remaining oil, salt, and pepper.
- Add the broccoli to the pan and redistribute into a single layer. Use a second pan if the vegetables are crowded.
- Roast for another 20–25 minutes, turning once, until the sprouts are tender, the onion has browned tips, and the broccoli has dark, crisp edges without becoming dry throughout.
- Toss with the lemon juice and taste for salt just before serving.
Notes
- Keep onion wedges attached at the root end where possible so they soften without burning into thin strands.
Crisp-Skinned Baked Potatoes
Baking directly on the oven rack gives russets a dry, crisp skin and fluffy interior. Splitting them immediately releases steam instead of letting the flesh turn dense.
Ingredients
- 4 medium russet potatoes, about 8–10 oz each
- 2 tsp olive oil
- 1 tsp kosher salt, divided, plus more to taste
- 4 tbsp unsalted butter
- to taste freshly ground black pepper
Instructions
- Heat the oven to 425°F. Scrub the potatoes, dry thoroughly, and prick each a few times with a fork.
- Rub with the olive oil and sprinkle with salt. Place directly on the middle oven rack, with a tray below to catch drips.
- Bake for 60–75 minutes, until the skins feel crisp and a thin knife slides easily through the centers. An internal temperature of about 205–210°F indicates a fluffy interior.
- Split lengthwise as soon as they come out of the oven. Gently squeeze the ends toward the center and fluff the flesh with a fork.
- Add 1 tablespoon butter to each potato and finish with pepper and additional salt as needed.
Notes
- Do not wrap the potatoes in foil; trapped steam softens the skins.
Overall Timing / Workflow
The potatoes set the schedule, while the vegetables share their oven temperature. Warming the crab last keeps its delicate meat from sitting hot.
Instructions
- 0:00 — Heat the oven to 425°F, prepare the potatoes, and start baking.
- 0:10 — Trim and cut the vegetables. Clean and crack the cooked crab if the seafood seller has not done so, then return it to the refrigerator.
- 0:35 — Begin roasting the Brussels sprouts and onion; add the broccoli 10 minutes later.
- 0:55 — Start checking the potatoes for tenderness and bring the crab steamer to a simmer.
- 1:00 — When the potatoes are nearly done, steam the crab. Finish the vegetables with lemon.
- 1:10–1:15 — Split and butter the potatoes, drain the crab, and serve everything immediately.
Notes
- If the potatoes need extra time, finish them before steaming the crab. The roasted vegetables can wait briefly in the switched-off oven.
Plating
Keeping the crab, vegetables, and potato in separate areas preserves their textures and leaves room for cracking shells.
Instructions
- Arrange a generous crab section across the top half of each large plate, with a fair share of claws and body meat.
- Spoon the roasted vegetables into a compact mound alongside the crab and place a split baked potato beside them.
- Serve lemon wedges, shell crackers, seafood picks, napkins, and a communal shell bowl at the table.
Leftover Path
Picking the crab while it is easy to handle makes leftovers more useful. Storing everything separately prevents shell moisture from softening the roasted vegetables and potatoes.
Instructions
- Within 2 hours of serving, pick remaining crab meat, check carefully for shell fragments, and refrigerate in a sealed container. Refrigerate potatoes and vegetables separately.
- Use crab within 3–4 days of its original cooking date, not 3–4 days after reheating. Serve cold with lemon or fold into warm food off heat to avoid toughening it.
- Use the potatoes and vegetables within 3–4 days. Reheat vegetables in a 400°F oven until hot and crisp at the edges.
- Split or cut leftover potatoes into chunks and reheat in a 400°F oven until hot throughout. Serve with the vegetables and gently warmed crab for a second, simpler meal.
