Creamy Cajun Potato and Shrimp Soup

Creamy Cajun potato and shrimp soup

This creamy Cajun potato and shrimp soup is bite after bite of sheer comfort food bliss. Gluten free, grain free, and full of seafood and veggie deliciousness, this south Louisiana comfort food recipe is a must-have for days when you need a good bowl of tasty, filling soup to knock the hangry out of you.

Mark and I are a big soup-and-salad couple. We both love the culinary juxtaposition of cold salad plate – warm soup bowl that keeps each dinner bite refreshing, filling, and interesting until the end. We eat soup when it’s cold and we eat soup when it’s hot, and we both seem to crave the same soup at the same time. Weird, but awesome.

Unlike my other favorite soup that takes several hours to make, this shrimp soup is ready in less than an hour. It’s one of those southern soup recipes that you can alter to what you have on hand quite easily, exchanging potatoes for corn and shrimp for crab if you want to shake things up a bit.

Like most of my other soup recipes, this soup starts with the Cajun trinity of onion, bell pepper, and celery simmering in my Lodge 7 quart cast iron Dutch oven. I also season the shrimp with a bit of dried basil, lemon zest, and black pepper to get them ready to enhance the flavor of the rest of the soup ingredients.

Once the seasoning vegetables are tender, add the mushrooms, potatoes, paprika, and SP&C to taste to the pot. Cook over medium heat for about 8 minutes, or until the mushrooms darken and the potatoes and veggies start to cook down and brown a bit.

Next, add shrimp stock and cook for about 10 minutes, or until potatoes are tender. Add the heavy cream, softened cream cheese and shredded cheese blend. Cook, stirring often, until the cheeses melt and the ingredients are well-combined.

Add seasoned shrimp, cook for an additional 2 minutes.

Top with green onion and fried sliced Paleo mushrooms (recipe coming soon) before serving, if you can wait that long…
