Oven-Roasted Dungeness Crab Recipe hits that sweet spot between buttery, garlicky richness and clean, briny crab flavor that tastes like a fancy seafood restaurant in your own kitchen. It suits date nights, holidays, or “I bought crab on sale and need dinner in under an hour” nights, and you can get it on the table in about 35–40 minutes total. I grew up on messy crab boils, so this version feels like the grown-up, sheet-pan version that still lets you lick your fingers at the table.

Why Oven-Roasted Dungeness Crab Recipe Is Worth It

Oven roasting concentrates the natural sweetness of Dungeness crab and lets the garlic butter cling to every nook and cranny. You get charred edges, juicy meat, and a sauce that begs for bread or rice.

You also skip the giant pot of boiling water and the seafood smell that lingers for days. A single sheet pan, some foil, and high heat handle most of the work while you pretend you slaved over it.

Ingredients You Need

Dungeness crab

2 whole cooked Dungeness crabs (about 1.5–2 pounds each), cleaned and cracked
- Ask the fishmonger to clean and crack them to save time.
- Use frozen pre-cooked crab if needed; thaw it in the fridge overnight.

Garlic butter sauce

8 tablespoons (1 stick) unsalted butter, melted
- Use salted butter and reduce added salt slightly if that sits in your fridge already.
4–6 cloves garlic, very finely minced or grated
- Use jarred minced garlic in a pinch, but fresh gives better flavor.
2 tablespoons extra-virgin olive oil
1–2 tablespoons fresh lemon juice, plus extra wedges for serving
1 teaspoon lemon zest (optional but brightens the flavor)
1 teaspoon kosher salt, plus more to taste
½ teaspoon freshly ground black pepper
½–1 teaspoon crushed red pepper flakes (adjust to your heat level)
1 teaspoon smoked paprika or sweet paprika
1 teaspoon Old Bay seasoning or similar seafood seasoning blend
1 tablespoon chopped fresh parsley (plus extra for garnish)
1 teaspoon sugar or honey (balances the brine and acidity; optional but nice)

Optional add-ons

1–2 tablespoons grated Parmesan for a slightly cheesy crust
1 tablespoon finely chopped green onion for garnish
1 small shallot, minced, for extra depth in the butter sauce

Pantry shortcuts & brand notes

Use a good-quality butter like Kerrygold or Plugrá if you want extra richness, but any real butter works.
Use store-brand Old Bay-style seasoning; most taste very similar.
Use bottled lemon juice if fresh lemons run out, but add a little zest from any citrus you have to keep the flavor bright.

Equipment list

Large rimmed baking sheet (half-sheet pan)
Heavy-duty aluminum foil or parchment paper
Large mixing bowl
Small bowl or measuring cup for the sauce
Kitchen shears or crab crackers (for serving)
Tongs or heatproof spatula
Microplane or fine grater (for garlic and zest, optional)

Quick Tips & substitutions

Preheat the oven fully so the crab roasts and caramelizes instead of steaming.
Pat the crab dry with paper towels so the sauce clings instead of sliding off.
Use ghee instead of butter if you want a nuttier flavor and a slightly higher smoke point.
Swap Old Bay with a mix of paprika, celery salt, garlic powder, and a pinch of cayenne.
Use lime juice instead of lemon for a slightly more tropical vibe.
Use frozen pre-cooked Dungeness crab; thaw it overnight in the fridge and pat it dry.
Use snow crab or king crab legs if you cannot find Dungeness; adjust roasting time slightly since legs cook faster.
Skip the crushed red pepper if kids or spice-sensitive guests join you and add hot sauce at the table instead.
Add a tablespoon of miso paste to the butter sauce for a deep umami twist.
Use gluten-free seafood seasoning if you avoid gluten, since some blends include trace gluten.

How to Make Oven-Roasted Dungeness Crab Recipe

Step 1: Preheat and prep the pan

Set your oven to 425°F (220°C) and let it heat fully. Line a large rimmed baking sheet with heavy-duty foil or parchment for easier cleanup. Lightly oil the foil or spray it so the crab does not stick.

Step 2: Prep the crab

If the fishmonger did not clean the crabs, remove the top shell, gills, and innards, then rinse quickly and pat dry. Crack the body into halves or quarters and crack the claws and thicker leg joints so the sauce can seep in. Pat every piece very dry with paper towels so the butter mixture adheres well.

Step 3: Mix the garlic butter sauce

In a small bowl or measuring cup, combine melted butter, olive oil, minced garlic, lemon juice, lemon zest, salt, pepper, crushed red pepper, smoked paprika, Old Bay, parsley, and sugar or honey if you use it. Whisk until the mixture looks smooth and emulsified. Taste a tiny bit and adjust salt, lemon, or heat to your liking.

Step 4: Toss crab with sauce

Place the crab pieces in a large mixing bowl. Pour about two-thirds of the garlic butter sauce over the crab and toss well so every piece gets coated. Reserve the remaining sauce for basting and serving.

Step 5: Arrange on the sheet pan

Spread the coated crab pieces on the prepared baking sheet in a single layer. Place the pieces so the exposed meat faces up when possible, since that browns nicely. Spoon any sauce left in the bowl over the top.

Step 6: Roast the crab

Slide the pan into the hot oven and roast for 12–15 minutes. Baste once halfway through with some of the reserved sauce, especially over exposed meat. Watch for bubbling sauce, lightly charred edges, and heated-through crab.

Step 7: Optional broil for extra char

Switch the oven to broil on high for 2–3 minutes at the end if you want more color. Keep a close eye on it so the garlic does not burn. Pull the pan when the crab looks glossy, sizzling, and caramelized in spots.

Step 8: Finish and serve

Transfer the hot crab to a platter. Drizzle with the remaining warm garlic butter sauce and sprinkle with extra parsley and green onion if you like. Serve immediately with lemon wedges, napkins, and tools for cracking.

Storage Success

Cool leftover Oven-Roasted Dungeness Crab Recipe to room temperature within 30 minutes, then move it to an airtight container and refrigerate it for up to 2 days. Reheat it in a covered baking dish at 325°F with a splash of extra butter or broth until warm, about 8–10 minutes. Use the leftovers in crab fried rice, crab pasta, or a crab omelet so the meat still tastes juicy and tender. Avoid freezing the cooked crab in sauce since the texture turns watery and less pleasant.
