Black Pepper Crab with Garlic Noodles

Jump to Recipe

Black pepper crab is a staple at Singaporean seafood houses, and the combination of cracked peppercorns, butter, and a savory soy glaze is genuinely hard to beat. Pairing it with garlic noodles turns a standalone shellfish dish into something that eats like a full meal.

I favor Dungeness or blue crab here – both hold up to the bold sauce without getting lost. If you’re buying live crab, ask the fishmonger to clean and halve it for you. It saves a lot of time at home.

The noodles are cooked separately and then finished in the same wok after the crab comes out, using the same high-heat technique that makes a black garlic ramen broth so deeply flavored. That way they pick up all the fond and residual butter from the pan without going soggy.

Everything comes together in about 40 minutes once your crab is prepped.

Why You’ll Love This Recipe

• One wok does both the crab and noodles
• Bold pepper-butter sauce clings to every piece of crab
• Garlic noodles soak up the pan drippings completely
• Ready in 40 minutes including noodle cooking time

Ingredient Notes

• Dungeness crab: Buy cleaned and halved from the fishmonger to cut prep time significantly. Blue crab or mud crab work just as well – adjust cook time down slightly for smaller crabs.
• Black peppercorns: Crack them coarsely in a mortar rather than using pre-ground pepper – you want texture and heat, not just spice. Use about 2 tablespoons whole peppercorns for 4 servings.
• Oyster sauce: Provides the savory backbone of the glaze. For a pescatarian-friendly swap, a mushroom-based oyster sauce works well and keeps the umami profile intact.
• Dark soy sauce: Adds color and a slightly molasses note to the sauce. Regular soy sauce can substitute but the color will be lighter and the flavor slightly thinner.
• Egg noodles: Fresh or dried both work – cook them just short of fully done since they finish in the wok. Thin wheat noodles or even spaghetti are workable substitutes.
• Unsalted butter: Used in two stages: first for building the pepper sauce, then for finishing the garlic noodles. Salted butter works but hold back on any added salt.
• Garlic: Minced finely for the noodles so it toasts evenly without burning. I use about 8 cloves total – 5 for the crab sauce, 3 for the noodle finish.

Ingredients

  

For the black pepper crab

• 1.5 kg Dungeness or blue crab, cleaned and halved ask fishmonger to clean and halve
• 2 tbsp whole black peppercorns, coarsely cracked
• 60 g unsalted butter divided into 2 additions
• 5 garlic cloves, minced
• 1 tbsp fresh ginger, minced
• 3 tbsp oyster sauce
• 1 tbsp dark soy sauce
• 1 tbsp light soy sauce
• 1 tsp sugar
• 60 ml chicken stock or water
• 2 tbsp neutral oil (such as vegetable oil)

For the garlic noodles

• 300 g dried egg noodles or fresh egg noodles cook until just shy of done
• 30 g unsalted butter
• 3 garlic cloves, minced
• 1 tbsp light soy sauce
• 1 tsp sesame oil
• 2 stalks sliced green onions for finishing
• 1 tsp white sesame seeds optional, for garnish

Method

 

Prep

1. Crack peppercorns in a mortar to a coarse, uneven grind - aim for rough chunks, not powder.
2. Pat crab pieces dry with paper towels on all sides.
3. Bring a large pot of salted water to a boil. Cook egg noodles for 1 minute less than package instructions. Drain and toss with sesame oil to prevent sticking. Set aside.

Cook the black pepper crab

1. Heat a wok over high heat until smoking. Add 2 tbsp neutral oil and swirl to coat.
2. Add crab pieces cut-side down in a single layer. Sear for 2 to 3 minutes until the underside shows some color, then flip each piece.
3. Push crab to the sides of the wok. Add 30 g butter to the center. Once melted and foaming, add garlic, ginger, and cracked peppercorns. Stir-fry for 60 seconds until fragrant.
4. Pour in oyster sauce, dark soy, light soy, sugar, and chicken stock. Toss everything together to coat the crab pieces evenly.
5. Cover with a lid and cook for 5 to 6 minutes on high heat, tossing once halfway, until the shell is fully orange-red and crab meat is opaque at the joints.
6. Remove the lid. Add the remaining 30 g butter off direct heat and stir until the sauce turns glossy and clings to the shell. Transfer crab to a platter.

Finish the garlic noodles

1. Without washing the wok, reduce heat to medium-high. Add 30 g butter to the residual pan drippings.
2. Add 3 minced garlic cloves. Stir-fry for 30 seconds until fragrant and just starting to turn golden at the edges.
3. Add the drained noodles and 1 tbsp light soy sauce. Toss continuously for 2 minutes until noodles are coated in the garlic butter and heated through.
4. Plate noodles alongside or under the crab. Garnish with sliced green onions and sesame seeds if using. Serve immediately.

Notes

If the pepper sauce tightens too much before serving, a tablespoon of warm stock loosens it back to a coating consistency without breaking the butter.

Tips for Success

• Crack peppercorns in a mortar to a coarse texture, not a powder, so each bite has distinct heat.
• Pat crab pieces dry before they hit the wok – moisture causes the butter sauce to splatter and dilutes the glaze.
• Cook noodles until just shy of al dente, then drain and finish them in the wok drippings over high heat.
• Keep the wok on high heat throughout the crab cook to get color on the shell and prevent steaming.
• Add the butter in two additions to the pepper sauce so it emulsifies rather than breaking into a greasy pool.

Variations

• Swap crab for large shell-on prawns and cut cook time to 4 minutes total for a quicker weeknight version.
• Add a tablespoon of sambal oelek to the pepper sauce for extra chili heat alongside the black pepper.
• Use rice vermicelli instead of egg noodles and finish with a squeeze of lime for a lighter plate.

Storage and Reheating

Leftover crab keeps in an airtight container in the refrigerator for up to 2 days. Store the noodles separately if possible – they hold their texture better and reheat more evenly.

To reheat, add a splash of water or chicken stock to a wok over medium-high heat, add the crab pieces, cover, and steam for 3 to 4 minutes until hot through. Reheat noodles separately in a pan with a small knob of butter.

Freeze only the sauce itself if you plan ahead – cooked crab and noodles do not freeze well. The pepper-butter glaze keeps frozen for up to 1 month.

Serving Suggestions

Serve the crab directly from the wok onto a large platter with the garlic noodles piled alongside or underneath. Have a stack of paper towels or finger bowls on the table – this is a hands-on dish and the pepper sauce stains.

A simple cucumber and vinegar salad on the side cuts through the richness of the butter sauce, the same way a bright green mango salad works alongside crispy skin snapper. Steamed jasmine rice works too if you want to stretch the meal for a larger group.

For drinks, a cold lager or a crisp dry Riesling handles the pepper heat without competing with the garlic notes, much like the pairing logic behind Szechuan wok dishes with bold spice.

FAQ

Why does my black pepper crab sauce look greasy instead of glossy?

The butter has broken rather than emulsified. Add it in smaller pieces over medium heat and stir constantly. If it breaks mid-cook, a tablespoon of cold water and quick stirring will bring it back.

Can I use pre-ground black pepper instead of cracked whole peppercorns in this recipe?

You can, but the texture and heat will be noticeably flatter. Whole peppercorns cracked in a mortar give the sauce its characteristic coarse bite – use at least coarsely ground pepper if whole peppercorns aren’t available.

How do I know when the crab pieces are fully cooked in the wok?

The shell turns bright orange-red and the meat at the thickest joint is white all the way through with no translucency. In a hot wok with a lid on, halved Dungeness crab takes about 6 to 8 minutes.

Can I make the black pepper crab sauce a day ahead and reheat it?

Yes – the sauce holds well in the fridge for up to 2 days. Reheat it gently in the wok before adding freshly cooked crab so you don’t overcook the shellfish.

What’s the difference between Singapore black pepper crab and chili crab?

Black pepper crab uses a dry, butter-based cracked pepper coating while chili crab is coated in a saucy tomato and egg-thickened chili gravy. Black pepper crab is drier and more intensely spiced, chili crab is saucier and slightly sweeter.

Is black pepper crab with garlic noodles gluten-free?

Not as written – oyster sauce, dark soy sauce, and egg noodles all contain gluten. Use tamari in place of soy sauce, a gluten-free oyster sauce, and rice noodles to make the dish gluten-free.
