Leftover Shrimp Boil Fisherman's Pie
This easy recipe for Leftover Shrimp Boil Fisherman's pie is a great way to use the leftovers from a shrimp boil in a rich and hearty casserole. Topped with mashed potatoes and baked, this dish throws in cajun spice.

Many of you long-time readers know that some of my best recipes have come from my (kind of obsessive) need to use leftovers as efficiently as possible. I absolutely hate throwing food away - it's a pet peeve of mine. So, if my family is sick of a meal we've been eating for a day or two, I'll often change it up a little by throwing it in a casserole or a baked dish.
I've found some pretty great recipes by doing this over the years (and saved a ton of money, to boot). Today's recipe is definitely one of those!

Over the summer, our family had a shrimp boil - and, if you've ever done one, you know that you have so many leftovers afterwards. Look, I love shrimp and potatoes as much as the next girl - but there are only so many single shrimp you can eat. So, instead of throwing those leftovers away (shudder...), I turned them into a casserole that my family ended up loving! I really wasn't originally planning on making this into a blog post, so this might not come across as the most photogenic recipe ever - but trust me, the flavors are unbelievable.
This would be a great way to use up really any kind of meat and potatoes meal with a few simple veggie/sauce changes. For more of a beef base, I'd use a darker sauce (maybe something similar to gravy). For chicken, you could even do a cream/alfredo based-sauce with this - that would be so yummy! And the veggie possibilities are endless. Peas, broccoli, carrots, or even mushrooms could be subbed in. Just use what you have - this is a versatile one!
