Pumpkin Lobster Mac and Cheese


"One Halloween I decided to try out a macaroni and cheese recipe using pumpkin, and it turned out to be a huge hit. The combination of the cheeses and the pumpkin made it so very rich and creamy. The next time I decided to make this dish I added some cooked lobster I had left over, and from there I just fell in love. I have had lobster macaroni and cheese dishes before, but never anything like this. All of this may sound strange and unusual but once you try this dish you will never get it out of your head. Garnish with fresh parsley and serve with fresh bread or dinner rolls."

This was amazing! The only thing I did differently was add more cheese of a different variety such as goat and munster. Even after I felt like I should have added more cheese and garlic. I'm mos...

We really liked this. I made it as stated in the recipe. Next time I will reduce or omit the lemon zest. The lemon flavor overpowered a little. I also prefer it a bit more creamy like it is befo...

It was good, but seemed like it was missing something.

Absolutely wonderful. I did not have shallots, so used onion and garlic from my garden, also replaced soft cheese with cream cheese - the consistency, taste and ease of making made this one of m...

Took this to our koi club pot luck. Everyone raved about it. I did up the amount of spices (as a pinch didn't seem to be quite enough), especially the hot sauce. I think I would use a brick ...

This was really yummy. I used a whole shallot and a whole can of pumpkin, because what was I going to do with the leftovers?!?! I think I ended up needing a little more flour than called for. ...
