This recipe for “Black and Blue” sauce is about as close to a family trade secret recipe as you can get, and when you put it on jumbo lump crab and a pile of grits? WOW, is it good. And the thing is, I’m not even Southern, I’m not even close to Southern (okay, maybe I am a little? Does Missouri count as the South??), but this recipe feels like an homage to Southern comfort cooking. “Black and Blue” sauce stands for Cajun blackening seasoning simmered with blue cheese. And while it sounds weird, you gotta try it. Even if you don’t like blue cheese, it melts into a creamy, spicy sauce that is somewhat reminiscent of vodka sauce, due to the distinct bite from the cheese. It’s unlike anything I can explain, and it is so uniquely delicious. Once you make this creamy sauce, you won’t be able to get it out of your head.
The reason I call it a “family trade secret recipe” is because it was first cooked for me by a family member. My uncle served it at his house over crab cakes, and I immediately was like “what is this???”
He explained to me he had it at a restaurant in South Carolina, where the owner of the restaurant group had it on not one, but TWO of his restaurant’s menus. It was just that popular. Luckily, my uncle was able to reverse engineer it, and then I was able to reverse engineer that, and that is the recipe you have in front of you today.
I put it on jumbo lump crab because I find that distinctly delicious, but once you try it I have no doubt you’ll think of thousands of other ways to use it.
What is “Black and Blue” sauce?
This sauce is called “Black and Blue” sauce for two reasons:
- It uses a “blackening” season spice blend – so, the Black!
- It then melts in blue cheese into the sauce, thus the Blue!
Of course, a few other things happen in order to make this a sauce, but you will be wowed by the results. Even if you have a few blue cheese skeptics, just get them to try this sauce once. It is not overtly “blue-cheese-y,” but instead it has a unique underlying flavor that melts perfectly with the blackening seasoning.
I had a few friends call this “vodka pasta” reminiscent when I was developing the recipe, and honestly, I take it as a compliment!

Where I get my jumbo lump crab
I find that the biggest roadblock for people when trying a new recipe is often the sourcing of ingredients. And I get it, finding easily accessible jumbo lump crab is not at every grocery store! And also…it can be pricey.
I tend to get my jumbo lump crab in a can. I know. Gasp. But canned crab is such high quality, and pound-for-pound you will be paying the same amount as if you were buying fresh crab legs. But you are just saving yourself a ton of work.
Here are few types of crab I like to use:
Blue Swimming Crab by Chicken of the Sea
Lump Premium Crab Meat by Queen ‘o’ The Ocean
How to prepare your jumbo lump crab
The crab will luckily soak in all the black and blue sauce as soon as you add it to the sauce. This is great for flavor, but not so great for texture and temperature. You want to ease the crab up to the same temperature as the sauce. I like to do this by adding a splash of water to help loosen the sauce around the crab, and then bring that to a simmer so the crab can slowly come to my desired temperature.
It is a small technique, but it only takes minutes!
What other ways can you use “Black and Blue” sauce?
When it comes to Black and Blue sauce, the world is your oyster! (No, literally, put it on oysters!).
I find this sauce is a great partner to seafood, but I’ve also seen people put it on Crispy Tofu, or even burgers, and have a great time. This sauce is a good friend to proteins!
Of course, I’m never going to say no to slathering your roasted vegetables with it. This sauce is meant for anything that needs a dressing, a dip, or some extra flavor.
FAQS
This recipe is tricky. It will keep well in the fridge for up to four days, but I recommend eating it as fresh as possible. This is just because jumbo lump crab meat is an investment, and I want you to have the best possible experience! However, my finacé has been tearing through the leftovers in our fridge and says they are fabulous.
Absolutely! Since this sauce has cheese and cream in it, it will thicken as you store it in the fridge. But you can store it in an airtight container for up to three days, then put it on the stove over medium heat and add 1/3 cup of water to thin it out. Bring it to a simmer and then it is ready to use!
Rice, couscous, farro, polenta, or any grain that is capable of soaking up sauce is great with this dish!
This recipe is not suitable for freezing. It is difficult to thaw and maintain the sauce’s emulsion!

This vegetable-filled soup tastes exactly like a wild mushroom stuffing, but a stuffing you can eat all season long! Which is exactly what I thought we should always be doing, by the way. It’s a crime stuffing isn’t a more popular year-round food. Here you can get all the flavors of mushroom leek stuffing, but filled with all the nutrition you need for a full meal. It’s a favorite dinner of mine, full stop.
This is one of those meals that I keep coming back to when I need comfort. It’s hearty and filling, while still being nourishing and packed with seasonal vegetables. Feel free to use any white fish in this one, although I do love sablefish for its rich texture that feels like a mix between salmon and swordfish.
I lovingly call these “Crabbie Patties,” because as a pescatarian, these crab salad sandwiches are everything I want to eat when my friends are all having burgers. It’s a lighter, refreshing sandwich, with a bright slaw and a light honey dijon dressing. It was actually inspired by a brunch I had in Edinburgh, where they served a crab salad on brioche with a honey mustard dressing and I thought it was inspired. I couldn’t get it out my head, which is why you find it now here… on my plate.

Jumbo Lump Crab with Black and Blue Sauce
This recipe is one of my absolute comfort food favorites. It’s a simple “black and blue sauce” – a Cajun blackening seasoning sauce with a combination of blue cheese (don’t knock it until you try it!) that spoons over jumbo lump crab, and is all served over grits. It’s hearty, savory, and best of all – easy. I love making it as a weeknight meal or a dinner party option for friends!
Equipment
-
1 medium pot
-
1 large sauté pan
Ingredients
- 1 cup white grits uncooked
- 1 teaspoon Diamond Crystal kosher salt
- 1 1-pound can of jumbo lump crab
For the Black and Blue Sauce
- 1 teaspoon each of onion powder, garlic powder, smoked paprika, dried thyme, dried oregano, and black pepper
- 2 tablespoons salted butter
- 1/3 cup heavy cream
- 3 ounces blue cheese
For serving
- Assorted tender herbs like dill, curly parsley and mint
- 4 small lemon wedges
Instructions
-
Begin the recipe with the grits. Add the one cup of grits to a pot with six cups of water. Bring this to a rolling boil and add 1 teaspoon of salt. Reduce to a simmer and let this simmer, stirring occasionally, for 40-45 minutes or until the grits have thickened to a porridge consistency. Taste and add more salt as preferred.
-
When the grits are 15 minutes away from being ready, begin the Black and Blue sauce.
-
Add 1 teaspoon each of onion powder, garlic powder, smoked paprika, dried thyme, dried oregano and freshly ground black pepper to a large sauté pan. Add 2 tablespoons of salted butter and set this pan over medium-low heat.
-
Allow the butter to melt, stirring constantly to let the spices begin to sizzle and darken.
-
Pour in the heavy cream and swirl to combine. Add in 1/4 cup of water to thin it out (it will rethicken, don’t worry).
-
Let this come to a soft simmer and crumble in the cheese in two batches. Stir to let the cheese melt into the sauce. Taste and season with salt as preferred, but I find I never need it.
-
Add the pound of jumbo lump crab to the sauce. Stir to combine, and add up to 1/2 cup of water to help thin out the sauce, if needed. Bring this to a simmer again to help warm up the crab.
-
Now the grits should be done. To serve, portion the grits in to four bowls and top each with a generous portion of the crab. Tear over some tender herbs and serve with a lemon wedge!
