Bring 1 inch of salted water to a boil in a large pot.
Add the crabs into a steamer basket or just pile them in the pot with the boiling water and steam with the lid on for 5 minutes.
Remove the crabs from the pot with tongs and let them cook until they can be easiliy handled.
Clean the crabs, removing the gills and rinsing out the yellow mush, (guts), before transferring to a sheet pan.
Combine the butter and olive oil in a small dish. Add half the garlic, half the parsley, the chili flakes and lemon juice.
Put the crab (or crabs) on a sheet pan and coat with the butter and olive oil mixture. Top with the remaining garlic and parsley.
Cook for 15-20 minutes. The cooking time will vary slightly based on how many crabs you’re cooking and the size of the crabs. For 1-2 average-sized crabs, check for doneness after 15 minutes.
Notes
Plan on one 2-pound(ish) Dungeness crab for each diner as a main course. Half a crab per person works as an appetizer. However, if you're feeding a crowd, you may want to roast a few extra crabs as these crabs are hard to resist!Leftovers - if you have any - should be refrigerated in an airtight container for up to three days.
