HOW TO SELECT THE RIGHT TYPE OF CRAB MEAT FOR CRAB AU GRATIN
EXPERT TIP: Lump crab meat is a bit pricey, so I usually go with a mix of lump crab and regular crab meat.
But, always go with quality.
Be sure to pick the crab over to remove any excess cartilage. I usually do this twice, just to make sure.
This sauce is rich and creamy, and the perfect compliment to the fresh crab.
Just place the crab in the bottom of the pan, and then pour that amazing sauce right on top.
Oh, yes…here we go.
Top it off with a combination of your favorite types of creamy, melting cheese.
USE A GOOD MELTING CHEESE, SUCH AS FONTINA, FOR CRAB AU GRATIN
Our favorite is a blend of Gruyere and Fontina. But, Monterey Jack, or Emmentaler, or even mozzarella will work. To learn all about the amazing History of Cheese, read this awesome article from the National Historic Cheesemaking Center.
And we love to serve these in individual cast iron skillets. But you can also use 1 large skillet when serving a group. It’s is beautiful in presentation, too!
Make this dish and be prepared for lots of ‘oohs’ and ‘ahh’s’. It’s not for the faint of heart, and one serving is a wonderful appetizer, probably for 2 – 4 people.
But, boy oh boy, is it good.. Crab lovers rejoice!

Jumbo Lump Crab Au Gratin
Ingredients
- 1/2 cup unsalted butter 1 stick
- 1 medium onion finely chopped
- 1 celery rib finely chopped
- 2 tbsp green onions sliced, save some for garnish
- 1 cloves garlic minced
- 2 large egg yolks slightly beaten
- 1 12 oz. can evaporated milk
- 2 tbsp all-purpose flour
- Juice of one lemon
- 1 tsp hot sauce
- 1 tsp Kosher salt
- 1/2 tsp cayenne pepper
- 1/2 tsp freshly ground black pepper
- 1/2 cup Gruyere cheese grated
- 1/2 cup Fontina cheese grated
- 1 lb lump crab meat picked over for shells and cartilage
Instructions
- Pre-heat the oven to 350°F.
- Melt the butter in a large skillet over medium-high heat.
- Add the onion, celery, green onions (white parts), and garlic, and cook, stirring, until the vegetables are softened, about 5 minutes.
- While the vegetables cook, vigorously whisk the egg yolks and evaporated milk together in a small bowl until well blended; set aside.
- Add the flour to the skillet, and blend well into the vegetables to create a white roux; be sure to not let the flour brown. About 2 minutes.
- Using a whisk, add the milk mixture, stirring constantly to blend into the roux mixture.
- Stir in the lemon juice, hot sauce, salt, cayenne, and black pepper, and continue to stir for another 4 - 5 minutes. (if sauce seems too thick, add a little water or milk to thin...should be the consistency of thick creamed soup).
- Remove from the heat, and fold in half the cheese; blend until it is totally melted and fully incorporated.
- Gently divide the crab meat among four mini oven-proof casseroles, or iron serving dishes; trying not to break up the crab lumps. Or, pour into 1 large cast iron skillet, or 8"x8" baking dish.
- Pour the cheese sauce over the crab, and then sprinkle with the remaining grated cheese on top.
- Bake until bubbly, about 15 minutes, then reset the oven for broil, and broil until the cheese begins to brown, about 5 minutes (keep an eye on this...don't let it burn!!).
- Remove from the oven, sprinkle with the green onions (green parts), and serve at once!

I have made Joy of Cooking crab gratin several times and while it’s good, it’s not something my family ever requests and I’ve always felt it was missing something. I picked up some fresh Gulf lump crab at the grocery store today and decided to google for another recipe to try with it. I came across this recipe, had all the ingredients except the Fontina and decided to try it. Wow!!! It is perfection. Total perfection. I used all Gruyere instead of half gruyere-half fontina but made it exactly as written other than that. The sauce does get too thick after whisking in the milk-egg mixture so I did have to thin it out with extra evaporated milk as suggested in the recipe. It smelled divine as it was cooking in the oven. My 5-year-old was literally jumping up and down excited to eat it because it smelled so good. He loved having his own little ramekin and I’ve honestly always loved entrees served that way too. Sooo flavorful and rich. Just fantastic! Never been to this site before. Will look through it now!!
Hi Emily! You have no idea how happy you just made us!! We are SO THRILLED you had major success with the crab au gratin! And your tweaks sound spot on! And that’s impressive that your 5-year-old loved it, too! Double win! And thanks so much for letting us know, that really does mean so much to us. Stay in touch, Emily!! All the best, Kris & Wesley
