Lemongrass–Black Pepper Dungeness Crab over SF-Style Vietnamese Garlic Noodles

Lemongrass–Black Pepper Sauce

Finely minced lemongrass and coarsely crushed pepper make an aromatic paste that clings to the crab shells. Butter rounds out the pepper, while a restrained amount of honey balances the salty fermented sauces.

Ingredients

• 3 stalks lemongrass, tough outer layers removed, tender lower cores very finely minced
• 1 large shallot, finely minced
• 6 cloves garlic, finely minced
• 1 1/2 tablespoons black peppercorns, coarsely crushed
• 1 tablespoon avocado oil
• 3 tablespoons unsalted butter
• 1 1/2 tablespoons gluten-free tamari
• 1 tablespoon gluten-free oyster sauce
• 1 teaspoon gluten-free fish sauce
• 2 teaspoons honey
• 1/2 cup water

Instructions

1. Pound the minced lemongrass briefly in a mortar, or chop it until almost paste-like; coarse, fibrous pieces will not soften enough during cooking.
2. Heat the avocado oil in a small saucepan over medium heat. Add the shallot and lemongrass and cook for 4–5 minutes, stirring, until softened and fragrant without becoming dark.
3. Add the garlic and cook for 1 minute. Lower the heat, add the butter and black pepper, and stir for 30–45 seconds until intensely fragrant.
4. Stir in the tamari, oyster sauce, fish sauce, honey, and water. Simmer gently for 2–3 minutes. Keep the sauce loose enough to pour; it will reduce further with the crab.

Notes

• The sauce should taste peppery and concentrated, but not harsh or burnt. Add a splash of water if it becomes oily or pasty before it reaches the crab.

Shell-On Dungeness Crab

Cracking the shells before cooking lets the sauce reach the meat while preserving the hands-on crab feast. A brief covered simmer cooks the thick body sections evenly, followed by an uncovered reduction to coat the shells.

Ingredients

• 2 whole raw Dungeness crabs, about 2–2 1/2 pounds each before cleaning, professionally dispatched and cleaned
• 2 tablespoons avocado oil
• 1 batch Lemongrass–Black Pepper Sauce
• 1/2 cup water, plus more as needed
• 1 cup loosely packed cilantro leaves and tender stems

Instructions

1. Keep the cleaned crab refrigerated until ready to cook. Remove any remaining gills and viscera, split each body into quarters with the legs attached, and crack the large claws and thick leg joints without shattering them. Pat dry.
2. Heat the avocado oil in a very large, deep skillet or wok over medium-high heat. Working in batches, sear the crab sections for about 2 minutes per batch, turning once, until the shells begin turning orange. Transfer each batch to a tray.
3. Return all the crab to the pan. Add the lemongrass–black pepper sauce and the water, turning the pieces to distribute the aromatics. Bring to a simmer and cover.
4. Cook at a steady simmer for 8–12 minutes, turning the sections halfway through. Add a little water if the pan threatens to dry out. The shells should be orange and the thickest body and claw meat opaque and pearly, reaching 145°F away from the shell.
5. Uncover and toss for 1–3 minutes, just until the sauce becomes glossy and clings to the shells. Remove cooked pieces temporarily if the sauce needs longer to reduce, then return them to coat.
6. Take off the heat and scatter with cilantro just before serving. Reserve all the pan sauce for the noodles and platter.

Notes

• Ask the fishmonger to dispatch, clean, and section the live crab shortly before pickup; transport over ice and cook the same day.
• If using fully cooked crab instead, sear briefly and simmer in the sauce only until hot, approximately 4–6 minutes, rather than following the raw-crab cooking time.
• Use two pans if necessary: crowding is manageable during the covered simmer, but the crab must fit well enough to turn and heat evenly.

SF-Style Vietnamese Garlic Noodles

Gently cooked garlic flavors the butter without becoming bitter. Starchy noodle water and finely grated Parmesan turn the butter and savory sauces into a glossy coating rather than a puddle of fat.

Ingredients

• 12 ounces gluten-free spaghetti, preferably a rice-and-corn blend
• 4 tablespoons unsalted butter
• 20 cloves garlic, finely minced or crushed
• 2 teaspoons gluten-free tamari
• 1 tablespoon gluten-free oyster sauce
• 2 teaspoons gluten-free fish sauce
• 1 ounce Parmigiano Reggiano, very finely grated
• 3 scallions, thinly sliced
• 1 teaspoon kosher salt, for the cooking water

Instructions

1. Bring a wide pot of water to a boil and salt lightly; the sauces and cheese will supply most of the seasoning. Cook the spaghetti until just shy of al dente according to its package directions.
2. Meanwhile, melt the butter in a large skillet over medium-low heat. Add the garlic and cook gently for 3–5 minutes, stirring frequently, until fragrant and softened but not browned.
3. Stir in the tamari, oyster sauce, and fish sauce, then remove from the heat until the noodles are ready.
4. Reserve 2 cups of noodle water before draining. Add the noodles and 1/2 cup of the reserved water to the garlic butter. Toss over medium heat for 1–2 minutes until the noodles are cooked and the sauce looks glossy.
5. Turn off the heat. Add the Parmesan a little at a time while tossing vigorously, loosening with additional warm noodle water as needed. Fold in the scallions.
6. Serve immediately, leaving the noodles slightly looser than seems necessary because they will continue to absorb sauce.

Notes

• Do not rinse the spaghetti; its surface starch helps bind the sauce. Gluten-free brands vary, so check doneness early and toss gently to avoid breaking the strands.
• If the cheese clumps or the sauce looks greasy, take the pan off the heat and toss in warm noodle water a tablespoon at a time.
• Keep the noodles moderately seasoned: the crab and its pepper sauce supply another layer of salt and umami.

Overall Timing / Workflow

Preparing the aromatic sauce first leaves only crab cooking and noodle finishing for the final stretch. The noodles are best emulsified just before they meet the crab.

Instructions

1. 0:00 — Keep the crab chilled while you mince the lemongrass, shallot, and both portions of garlic. Crush the pepper, grate the cheese, and prepare the herbs.
2. 0:15 — Make the lemongrass–black pepper sauce. Set a pot of noodle water over high heat.
3. 0:25 — Section and crack the cleaned crab if needed, then pat dry. Warm the serving bowls or platter.
4. 0:35 — Begin searing the crab. Once it is covered and simmering, start the noodles, adjusting for their package cooking time.
5. 0:40 — Gently cook the garlic in butter in a separate skillet. Check and turn the crab.
6. 0:50 — Check crab doneness and reduce its sauce. Finish the noodles with their cooking water, Parmesan, and scallions.
7. 0:55 — Plate immediately with cilantro and all the crab pan sauce.

Notes

• Allow additional time if working in several crab-searing batches. If the crab finishes first, hold it covered off the heat briefly rather than keeping it at a simmer.

Plating

A noodle bed catches the aromatic crab juices, while a shallow platter gives diners room to lift and crack the shell-on pieces.

Instructions

1. Twirl the hot garlic noodles into four wide, shallow bowls, or spread them across a warmed family-style platter.
2. Arrange the crab body sections and claws over the noodles, keeping some noodles visible around the edges.
3. Spoon the coarse black pepper and lemongrass sauce over the crab and into the noodles. Finish with the cilantro.
4. Set out shell crackers, seafood picks, a shell bowl, and plenty of napkins.

Leftover Path

Picking the crab while it is easy to handle makes leftovers more useful and allows gentle reheating without repeatedly cooking the shells and meat.

Instructions

1. Pick leftover crab meat from the shells once cool enough to handle, checking carefully for shell fragments. Refrigerate the meat with a little crab sauce in a shallow covered container; store the noodles separately.
2. Refrigerate within 2 hours of serving and use within 2 days for best quality.
3. Reheat the noodles in a covered skillet over medium-low heat with a splash of water, loosening and turning gently. Add the picked crab and its sauce near the end and heat leftovers to 165°F without prolonged simmering.
4. Finish with fresh cilantro or scallion if available.
