What is Pappadeaux's Alexander sauce?

Alexander sauce is Pappadeaux's signature cream seafood sauce — a butter-and-flour roux enriched with clam juice and heavy cream, seasoned with white pepper and cayenne, and finished with small shrimp and lump crab meat. It is a house name the restaurant uses for this specific sauce rather than a standard culinary term. The clam juice is the defining ingredient; it gives the sauce a briny, oceanic depth that distinguishes it from a plain béchamel or an Alfredo. The sauce is versatile at the restaurant and appears over several dishes beyond stuffed shrimp, including stuffed flounder and crawfish étouffée variations. At home, 8-ounce bottles of clam juice (Bar Harbor, Snow's, or Doxsee brand) are sold in the canned fish aisle at most supermarkets.

What size shrimp should I use for Pappadeaux stuffed shrimp?

Use colossal shrimp — U/10 (under 10 per pound) or 8-12 count. These are the largest supermarket shrimp and they are the right size for stuffing: big enough to hold a generous mound of crab filling, with enough cooking time in the oven for the stuffing to brown without overcooking the shrimp before it does. Jumbo shrimp (16-20 count) will work in a pinch — reduce the stuffing to about 2 teaspoons per shrimp and check for doneness at 12 minutes. Anything smaller than jumbo will be done before the stuffing can brown. If your store sells them frozen as 'colossal' without a count, look for shrimp that are at least 2 inches long before butterflying — that is the right size.

How do I butterfly a shrimp for stuffing without cutting through?

Peel and devein the shrimp, leaving the tail on. Lay the shrimp on its side and make a deep cut along the curved back — the side that was deveined — running from just behind the head section to just before the tail. Cut about three-quarters of the way through the flesh; stop before cutting completely through. The shrimp should open like a book when you press it flat, with the two halves splayed out and a natural indentation running down the middle where the stuffing will sit. If you cut too deep and the shrimp splits, it still works — just press the stuffing firmly onto both halves. The tails stay on for presentation and give diners a handle.

Can I use imitation crab meat in the stuffing or sauce?

You can use it in the stuffing, but the character of the dish changes. Real lump crabmeat has a delicate sweetness and a slightly fibrous texture that breaks apart in large, visible chunks — you can see and taste the crab in each bite. Imitation crab (surimi, made from pollock) is starchier and sweeter, with a texture that turns rubbery under heat. If budget is the issue, use real claw meat (sold in cans or small tubs, much cheaper than lump but still real crab) rather than imitation — claw meat has more flavor than imitation and holds its texture better when baked. For the Alexander sauce, do not use imitation crab at all; the sauce is finished off-heat with the crab for just a few minutes, and imitation crab will taste noticeably synthetic in that delicate cream sauce.

How do I keep the stuffing from falling off the shrimp during baking?

Two things help: dry hands and a firm press. The stuffing mixture should be cohesive but not wet — if yours feels loose or crumbly, refrigerate it for 20 minutes before using, which firms up the mayo and lets the crackers absorb moisture from the crab. When mounting the stuffing onto the butterfly, press each mound firmly with your fingertips in a dome shape; you are essentially shaping it like a small crab cake that happens to be sitting on a shrimp. Make sure each shrimp is lying fully flat on the baking sheet — any tilt lets the stuffing slide off during baking. Some cooks pipe a thin line of mayo along the butterfly channel before adding the stuffing as additional adhesive; it is a legitimate trick if your stuffing is loose.

Can I make the stuffed shrimp and Alexander sauce ahead?

The stuffed shrimp can be assembled and refrigerated, covered, up to 4 hours before baking — any longer and the crackers in the stuffing absorb moisture from the crab and the texture goes pasty. The Alexander sauce can be made up to 2 days ahead and refrigerated without the shrimp and crab added; reheat it gently over low heat and stir in the raw shrimp and crab just before serving. Do not freeze either component: the stuffed shrimp becomes waterlogged on thawing and the cream sauce separates. If you are entertaining, the most practical approach is to make the sauce base (through the simmering step, before the seafood) earlier in the day, then bake the shrimp 20 minutes before sitting down to the table and finish the sauce with the seafood while the stuffed shrimp rest for 2 minutes out of the oven.

What is the difference between Pappadeaux's stuffed shrimp and their stuffed flounder?

The stuffing is virtually identical — the same crab-and-cracker mixture with Old Bay and Dijon — but the cooking technique and the result differ meaningfully. Stuffed flounder is a whole or filleted flounder butterflied and baked with the stuffing inside; the flat fish holds the stuffing enclosed rather than mounded on top, and the flounder's mild flavor lets the crab come forward more than the shrimp does. The stuffed shrimp version has a firmer, more assertive shellfish flavor from the shrimp itself, a crisper top on the stuffing because it's exposed to direct oven heat, and a higher stuffing-to-protein ratio per bite. Both are finished with Alexander sauce. At the restaurant, the stuffed flounder typically comes as a larger, single presentation; the stuffed shrimp come as multiple pieces arranged over rice.

Pappadeaux’s stuffed shrimp is the dish people from Texas, Georgia, and the Gulf South remember most clearly and search for most persistently once they’ve moved away from Pappadeaux territory. Colossal shrimp butterflied and loaded with a crab stuffing, baked until golden, and finished with a ladleful of Alexander sauce over rice — it is a Gulf Coast steakhouse meal in a single plate. The restaurant charges $34 to $42; this version lands at about $22 and takes 45 minutes start to finish.

There are two techniques that actually matter here. First, in the crab stuffing: do not overmix. You want visible chunks of lump crab in every bite — if you fold aggressively you shred the crab into paste. Second, in the Alexander sauce: cook the flour in the butter for a full 2 minutes before adding any liquid. Less than 2 minutes and the finished sauce will have a faint raw-starch taste on the back of the palate that cream and seasoning cannot hide.

What Is Alexander Sauce?

Alexander sauce is Pappadeaux’s house cream seafood sauce — clam juice and heavy cream built on a butter-flour roux, seasoned with white pepper and cayenne, and finished with small shrimp and lump crab meat. It is not a beurre blanc, not an Alfredo, and not a bisque; it is its own Gulf Coast cream sauce. The clam juice is what sets it apart from a simple cream sauce. It contributes a concentrated oceanic brininess that keeps the sauce from tasting purely rich and fatty — there is real shellfish depth in every spoonful. One 8-ounce bottle of clam juice (Bar Harbor, Snow’s, and Doxsee are the common brands, all equivalent in the canned fish aisle) is exactly what this recipe needs.

The sauce is built on protein twice: small shrimp go in first because they need 2 to 3 minutes of heat to cook through; lump crab goes in last, off the heat, because it is already cooked and only needs to warm — additional heat breaks the crab apart and turns it stringy.

The Crab Stuffing

Pappadeaux’s crab stuffing is a seafood-forward riff on a classic crab cake: lump crab, crushed crackers for binding, scallions and red bell pepper for color and brightness, mayo for moisture, Old Bay for seasoning. The key is restraint with the binders — the stuffing should taste like crab with some textural interest from the crackers, not like crackers with some crab in them.

The cracker-to-crab ratio is approximately 1:2 by volume (half a cup of crushed crackers to 8 ounces of crab). If you want a slightly crisper, drier stuffing, reduce to 1/3 cup crackers. If you want a softer, moister stuffing that soaks up more of the Alexander sauce when it is ladled over, increase to 2/3 cup. The stuffing firms up significantly when refrigerated for 15 minutes before mounting — skip the refrigeration step only if you are confident it holds together at room temperature.

Getting the Stuffing to Stay On

The two failure modes are loose stuffing (too much mayo, not enough crackers, or the crab is very wet from thawing) and stuffing that slides off before it has a chance to brown. Both are fixable:

If the stuffing is too wet: Fold in another 2 tablespoons of crushed crackers and refrigerate 10 more minutes before using.
If the stuffing slides off: Press a thin smear of extra mayo along the butterfly channel before mounting the stuffing — it acts as an adhesive. Make sure every shrimp is completely flat on the pan before you put it in the oven; even a slight tilt causes the dome to slide as it heats up.

The stuffing should hold a mound shape when pressed — if it falls apart in your hands, it will not survive baking. Test one shrimp: if the stuffing holds its shape out of the oven for 30 seconds, the rest will too.

Tips for Perfect Results

Pick crab carefully. Lump crab comes in tubs in the refrigerated seafood section (Phillips, Chicken of the Sea, and store brands). Open the tub and run your fingers through the meat before using — commercial crab processing misses shells occasionally, and biting into a shell in the stuffing is a jarring experience. 30 seconds of picking before you fold everything together is worthwhile.

White pepper in the sauce, not black. The classical French mother-sauce tradition uses white pepper in cream sauces because it disappears into the pale sauce without speckling it dark. In this recipe, white pepper also has a slightly different, slightly more floral heat than black pepper — correct for a Gulf Coast cream sauce. If you only have black pepper, use it sparingly.

Serve the Alexander sauce with genuine generosity. The sauce is meant to pool at the base of the plate and soak into the rice below the shrimp. If it looks like you’re saucing sparingly, add more. The ratio at the restaurant is roughly equal volumes of sauce and rice at the base of the bowl.

What to Serve With It

The dish is a full meal on its own, so keep sides simple and bright. Pappadeaux classically pairs it with hush puppies, which balance the cream sauce with a fried, slightly sweet corn element. A simple green salad with a vinaigrette cuts the richness well. Crusty French bread for sauce-mopping is essential if you are not serving hush puppies. Skip additional starches — the rice at the base of the plate already handles that role.

Storage and Reheating

Leftovers: Store the stuffed shrimp and Alexander sauce separately. Shrimp: refrigerate in a covered container up to 2 days. Sauce: refrigerate up to 3 days. Do not freeze — the cream sauce separates and the stuffed shrimp turn watery on thawing.

Reheating: Rewarm the stuffed shrimp on a wire rack over a sheet pan in a 300°F oven for 8 to 10 minutes — the stuffing stays somewhat crispy and the shrimp heats through without turning rubbery. Reheat the sauce in a saucepan over low heat, stirring gently; if it has thickened in the fridge, add 2 to 3 tablespoons of cream or milk and stir until smooth. Do not microwave the stuffed shrimp; microwaving steams the stuffing and makes it soggy.
