    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!
