Instructions

1
To a slow cooker, add the mini red potatoes, dehydrated minced garlic, Old Bay seasoning, Cajun spice, bouillon powder, and smoked paprika.
2
If using, add the cayenne pepper and crushed red pepper flakes. Then add the bay leaves, oil, defrosted chopped onion, and the stick of butter.
3
Pour in enough water to cover all the ingredients.
4
Cover the slow cooker and cook on high for 2 hours, or until the potatoes are tender.
5
Add the defrosted corn on the cob to the slow cooker. Cover and continue to cook for another 30 minutes.
6
Stir in the lemon juice, then add the surimi (or other seafood of choice).
7
Cover and cook for a final 15-20 minutes, just until the surimi is heated through.
8
Serve immediately, ladling the flavorful broth over each plate. Garnish with fresh parsley if desired.

Tips & Notes

Pro tips

Layer potatoes on the bottom of the slow cooker first—they take longer to cook than seafood and benefit from direct heat contact.
Don't lift the lid frequently; each opening extends cooking time by 15-20 minutes in a slow cooker.
Test potatoes for doneness before adding seafood; they should be fork-tender but not falling apart.
Adjust spice levels by reducing cayenne or red pepper flakes rather than Old Bay—the latter provides essential seafood-boil flavor.

Substitutions

Chicken bouillon powder → vegetable bouillon or seafood bouillon (maintains broth depth)
Old Bay seasoning → Zatarains seafood boil seasoning (similar Cajun profile)
Smoked paprika → regular paprika (loses smoke note but retains color and mild flavor)

Storage & make-ahead

Store leftovers in an airtight container in the refrigerator for up to 3 days; reheat gently in the slow cooker on low or in a pot on the stovetop with a splash of water to prevent drying.

Equipment

slow cooker (4-6 quart recommended)

Common Questions

Can you make this on the stovetop instead of a slow cooker?

This recipe is specifically designed for slow cooker use. For stovetop preparation, you would need to modify cooking times and liquid ratios significantly, as slow cookers use moist, enclosed heat.

When should I add the seafood to avoid overcooking?

Add seafood during the final 20-30 minutes of cooking, depending on your slow cooker's temperature and the size of your seafood pieces, to prevent them from becoming tough or rubbery.

Can you scale this recipe up for a crowd?

Yes, you can double or triple ingredients, but use a larger slow cooker (6-8 quart) to ensure even cooking and proper heat distribution.

What can I substitute for Old Bay seasoning?

Use a combination of paprika, celery salt, black pepper, and cayenne in equal proportions, or use another seafood boil seasoning blend with similar spice profiles.
