Jumbo shrimp are butterflied and filled with a gently seasoned lump crab mixture, topped with panko and broiled until the filling is golden and the shrimp are opaque. A warm cowboy butter—melted butter brightened with lemon, garlic, smoked paprika, chives and a touch of cayenne—is drizzled over each portion. Serve immediately with lemon wedges and remove toothpicks before plating.
The sizzle of butter hitting a hot pan and the smell of crab meat toasting under a broiler will forever remind me of the weekend my cousin walked into my kitchen and declared we were going to make something ridiculous. We had shrimp in the freezer and crab from the fish market and nowhere to be except hungry. Three hours later we were standing at the counter eating straight off the sheet pan because plates felt unnecessary.
I have made these for backyard dinners where everyone stood around the grill instead of sitting down and for a quiet Tuesday when I just wanted something that felt a little fancy. My neighbor once peeked over the fence asking what smelled so good and ended up staying for the whole batch. There is something about shrimp and crab together that makes people slow down and pay attention to what they are eating.
Ingredients
- 16 jumbo shrimp (peeled, deveined, tails on): The larger the shrimp the easier they are to butterfly and stuff so do not settle for medium here.
- 227 g lump crab meat: Pick through it carefully for stray shell fragments because nothing ruins a bite faster than crunchy surprises.
- 1/4 cup mayonnaise: Binds the filling without making it heavy and keeps the crab cakes moist inside the shrimp.
- 1 large egg (lightly beaten): Helps hold the filling together during baking so it does not fall apart when you try to serve.
- 1 tsp Dijon mustard: Adds a subtle tang that most people cannot identify but everyone notices when it is missing.
- 1 tsp Worcestershire sauce: Deepens the savory character of the crab filling without overpowering the delicate seafood.
- 1/2 tsp Old Bay seasoning: A classic pairing with crab that brings celery salt and paprika into the mix.
- 1/4 tsp black pepper: Just enough warmth without competing with the cayenne in the cowboy butter.
- 1/4 cup finely diced celery: Provides a gentle crunch that contrasts the soft crab meat beautifully.
- 1/4 cup finely diced red bell pepper: Adds sweetness and color making the filling look as good as it tastes.
- 1 tbsp fresh parsley (chopped): Freshness matters here so skip the dried version if you can.
- 1/2 cup panko breadcrumbs: Lighter than regular breadcrumbs and gives the filling structure without turning it dense.
- 113 g unsalted butter (melted): The base of cowboy butter so use good butter because you will taste the difference.
- 1 tbsp fresh lemon juice: Brightens the rich butter and ties the whole dish together.
- 2 cloves garlic (minced): Raw garlic in melted butter creates an aggressive aromatic that mellows beautifully on the shrimp.
- 1 tbsp fresh chives (chopped): Their mild onion flavor is gentler than scallions and works better with delicate seafood.
- 1/2 tsp smoked paprika: Gives the butter a rust color and a whisper of campfire without actual smoke.
- 1/4 tsp cayenne pepper: Heat that builds slowly and keeps each bite interesting.
- 1/2 tsp crushed red pepper flakes: Rounds out the spice with a different kind of heat than cayenne alone.
- 1/4 tsp kosher salt: Seafood needs salt to shine and this amount lets everything else speak too.
- Freshly ground black pepper (to taste): Finish the cowboy butter with a few generous turns from the mill.
Instructions
- Prepare your oven and pan:
- Heat the oven to 220 degrees Celsius which is 425 Fahrenheit and line a baking sheet with parchment paper or a light coat of oil so nothing sticks later.
- Butterfly the shrimp:
- Run a sharp knife along the back of each shrimp without cutting all the way through then press them open flat on the sheet pan like little beds waiting for their filling.
- Mix the crab filling:
- In a medium bowl fold together the crab meat, mayonnaise, egg, Dijon, Worcestershire, Old Bay, pepper, celery, bell pepper, parsley, and panko until just combined and stop there because overworked crab turns mushy.
- Stuff each shrimp:
- Shape one to two tablespoons of filling into small ovals and gently press them into the open side of each shrimp securing with toothpicks if they seem restless.
- Make the cowboy butter:
- Melt the butter in a small saucepan then stir in lemon juice, garlic, parsley, chives, smoked paprika, cayenne, red pepper flakes, salt, and pepper keeping it warm on the lowest heat.
- Brush and bake:
- Brush some of that golden butter over each stuffed shrimp then slide the pan into the oven for 14 to 16 minutes until the shrimp turn opaque and the filling turns golden.
- Finish under the broiler:
- Hit them with the broiler for the final minute or two if you want deeper color and a slightly crisp top that makes the whole kitchen smell incredible.
- Drizzle and serve:
- Pour the remaining warm cowboy butter over the hot shrimp right out of the oven and serve with lemon wedges and extra butter on the side for dipping.
The first time I served these at a dinner party my friend held one up and said it looked too pretty to eat then ate four of them in ten minutes. That pretty much sums up the experience.
Choosing Your Seafood Wisely
Fresh lump crab from a fish counter will always give you the best texture and sweetest flavor but a good quality canned crab works when you are in a hurry or on a budget. For the shrimp look for shells that still have a slight sheen and avoid anything with a strong fishy smell because that only gets worse in the oven. Frozen jumbo shrimp are perfectly fine if you thaw them overnight in the refrigerator rather than rushing them under warm water.
Making It Your Own
A dash of hot sauce in the crab filling wakes up the flavors without turning it spicy and a handful of minced jalapeno in the cowboy butter changes the whole personality of the dish. You can swap the panko for gluten free breadcrumbs if needed and no one at the table will notice the difference. For a lighter version try brushing with olive oil instead of butter though you will lose some of that rich indulgent character that makes this recipe special.
Getting The Timing Right
The beauty of this dish is that most of the work happens upfront so you can assemble everything ahead and pop it in the oven when your guests arrive. The cowboy butter can be made a day ahead and gently reheated which actually helps the flavors meld together better.
- Prepare the crab filling up to four hours ahead and keep it covered in the refrigerator.
- Stuff the shrimp no more than 30 minutes before baking so they stay firm.
- Always serve immediately because reheated shrimp never tastes as good as fresh from the oven.
Some recipes become favorites because they are easy and some because they are impressive but this one earns its place by being both. Make it once and you will find yourself reaching for it every time you want to turn an ordinary evening into something worth remembering.
Recipe Q&A
- → How do I prevent the crab filling from becoming dense?
-
Gently fold the crab with the mayo, egg and panko—avoid overmixing. Keep the mixture light and slightly loose so the filling stays tender after broiling.
- → Can I make the cowboy butter ahead of time?
-
Yes. Make the butter in advance and keep it warm or reheat gently. If chilled, rewarm slowly so the herbs and garlic infuse without burning.
- → What’s the best way to secure the stuffing during cooking?
-
Gently press 1–2 tablespoons of filling into each butterflied shrimp and use a toothpick if needed. A light brush of butter before baking helps the top brown evenly.
- → Should I broil the whole time or bake then broil?
-
Bake at a high temperature until the shrimp are nearly done, then broil 1–2 minutes to achieve a golden crust without overcooking the shrimp.
- → How can I make this gluten-free?
-
Substitute gluten-free panko or crushed gluten-free crackers in the crab mixture to maintain texture while keeping it gluten-free.
- → What wine pairs well with these flavors?
-
Choose a crisp, unoaked white such as Sauvignon Blanc or a lightly oaked Chardonnay to complement the lemony butter and the sweet crab meat.
