Tips & Variations for perfect craw fish soup

- Seafood variation: Swap crawfish with shrimp or crab if crawfish is hard to find.
Storage and Freezing Tips
Store leftover corn,crawfish and potato soup in an airtight container in the refrigerator for up to 3 days.
For longer storage, freeze in freezer-safe containers or portion into Souper Cubes. Once frozen solid, transfer the blocks to a freezer-safe zipper bag for easy grab-and-heat servings.
Instructions
- Prep the ingredients: Wash and dice the potatoes into bite-sized pieces. Chop the onions.
- Sauté: Heat oil in a pot, add onions, and cook for about 2 minutes until translucent. Stir in the diced potatoes and cook over medium heat.
- Add seafood and corn: Rinse the frozen crawfish (or langostinos) and add them along with the corn.
- Simmer: Pour in the broth and seasonings. Cover, bring to a boil, then reduce heat to medium-low and let simmer until potatoes are tender.
- Thicken: In a small bowl, mix cornstarch with a little hot soup to create a slurry. Stir it back into the pot to avoid lumps.
- Finish & serve: Once the vegetables are soft and the crawfish are firm, garnish with fresh parsley and serve hot.
Notes
- Corn: Fresh corn works best in summer, but frozen or canned corn works well year-round.
- Crawfish: Use peeled crawfish tails. If unavailable, shrimp or crab are great substitutes.
- Potatoes: Russet or Yukon gold potatoes give the soup a creamy texture.
- Spice level: Add cayenne or hot sauce for extra heat.
Special Note
Every Cajun family has its own way of making crawfish soup. If you’re using store-bought Cajun seasoning, check the salt level—some blends are very salty. Adjust the seasoning gradually to avoid oversalting your soup.
