We just came back from visiting my parents in the Florida Keys for a week of fun in the sun (and watching coronavirus coverage … and hoping things weren’t getting as bad as we thought). We love getting out of the cold of New England and visiting our Mimi and PopPop. Aside from the family time, each year, I look forward to some amazing seafood, specifically blackened fish. As you know, we get amazing seafood here on the Cape. But those restaurants down in the Keys know how to do blackened fish and seafood unlike any place up here. So, now I am on a mission to make some really good blackened seafood. Starting with this blackened shrimp.

How do you make blackening seasoning?

Don’t let this long(ish) list of ingredients scare you. You probably have all of the spices in your spice drawer. Blackening blends can vary, but this is a combination that we really like. Combine the spices with butter and magic happens. Feel free to tweak according to your taste. I don’t like a lot of heat, so if you prefer something spicier, add some cayenne pepper to the mix.

  • Ground cumin
  • Chili powder
  • Garlic powder
  • Dried oregano
  • Kosher salt
  • Ground black pepper

Aside from shrimp, this blackening seasoning would also be great on salmon and any white fish.

Are these Blackened Shrimp Tacos easy and quick enough for a weeknight meal?

Yes! They’re ready in 20 minutes, as long as your shrimp are thawed. Thaw your shrimp overnight in the fridge (do not thaw at room temperature) or run them under cold water for 5-10 minutes until thawed. And, these shrimp tacos utilize many fridge and pantry staples – so you likely have most of the ingredients on hand. The only items I had to purchase for this recipe were: cilantro and sour cream. We always keep:

  • frozen shrimp
  • spices
  • tortillas (my kids eat tortillas at EVERY meal, no joke)
  • cabbage (red or green)
  • red onion
  • lime
  • avocado

Any tweaks I can make to the recipe to make it even quicker?

Yep! You can skip the quick pickled onions and just use diced red onion. You can also just use plain sour cream vs stirring in the garlic power and cumin. But honestly, both those steps are so quick and they make the tacos extra special – so, if you can spare the extra 2 minutes, do it.

Are frozen shrimp a staple in your freezer? If not (and you love shrimp), they should be. Unlike most other seafood/meat/poultry, they thaw very quickly, so even if you haven’t planned ahead for dinner, dinner can still be ready in less than 30 minutes. And they cook in less than 5 minutes … how can you beat that?! We love using frozen shrimp for: stir-fries, grilling, salads, fresh spring rolls, pasta … and yep, tacos!
