Tip!

This casserole is easy to vary, by substituting the crab meat for canned tuna, or other cooked fish like mackerel or shrimp. If you would like to make this dish even more gourmet, feel free to use parmesan cheese or gruyère for some extra wonderful layers of flavor. You may like spinach, olives, sundried tomatoes - feel free to express your inner foodieness.

    This is actually one of my favorites. The only thing I changed was more celery and onion. I made for my family and everyone loved it!

    I know I've said this before but canned crab is certainly NOT a budget ingredient here. I could buy almost 2kg of ground beef or 1.5kg of chicken thigh fillet for the same cost as this much canned crab

    I’d like to make a suggestion that you put in the recipe the size of baking dish to use. As for the price of the crab, yes it is pricey but we were able to buy canned crab for 15.00 which is what the recipe called for and while that is pricey split into the 4 servings, it can put to 3.75/serving. Since we do t eat this every night, it was a nice treat and very tasty. Thanks Marsha

    In the tips, it says you can easily replace with canned tuna or other fish.

    This looks great. I'm going to try it this weekend, but with vegan cheese. I'm doing keto as an limited egg+fish (mostly) vegetarian, and so far I'm finding that it's easy to substitute vegan cheeses in recipes. Throwing this out there for others who may not be able to do dairy. If you could note non-dairy cheese substitutions, it would be really helpful!

    Has anyone tried forming these into patties instead of the casserole dish? Was thinking of trying it that way instead...

    Had this today for lunch and it's very good! I used canned crab meat and it was just fine. In fact, I think next time I'll add a can of shrimp, too. It "shred-y" like the crabmeat and, I think, would add even more seafood flavor. I added about 1/4 of a red bell pepper and I'd add a bit of lemon juice to brighten the flavor. Mmmmm.

    I leave out the onion and celery just because I don't love the texture. Instead, I add fresh spinach which adds colour and greens to the meal. I also use a combination of cheddar cheese, cheddar with habenero and monteray jack with jalepeno. Works perfectly with the "cajun." Often serve with one of Diet Doctor's brussel sprout dishes. Great combinations.

    Great ideas! Thanks for sharing!

    I didn't have enough shredded cheddar, so I mixed 8 oz cheddar, 4 oz cream cheese. Cream cheese and crab is always a winner, was awesome and the texture was great!

    Can I use flaked crab meat that comes in an air tight bag instead of the canned?

    Yes, that should be fine.

    How much does the recipe make? I wanted to use some 10 ounce soufflé dishes for serving. What's your best guess on how many dishes will be required?

    That's a tough one without having it right in front of me. A 10 oz dish should be fine for one serving. You can always make a 1.5 or a double batch and freeze the leftovers to be safe.

    Thanks.

    This was really good! I loved it. Easy to make and reheats well. I did add a sprinkle of extra cayenne pepper on top to make it a bit more spicy - my taste buds are getting old!

    Hi friends! I heard imitation crab meat is high in carbs- is this the same thing with canned- is it the same type of meat (or real?!). I could not find canned on this grocery run so I am a bit confused...Thanks in advance for any information

    In most cases, canned crab meat is 100% crab rather than the starchy/fish glue that is imitation crab. Different stores may have it in different locations, please ask your store's customer service desk if you need assistance locating canned 100% crab.

    Thank you so much- the frozen imitation was almost 30g in carbs!
