| Black Pepper 🌶️ | 1 tbsp | Freshly ground preferred |

The paprika is the foundation—sweet or smoked both work, but smoked adds that classic depth. Penzeys has excellent quality, or hit the bulk bins at Whole Foods for smaller quantities. Freshness matters here; if your spices have been sitting for over a year, start fresh. Bay leaves should be whole and crushed just before mixing to release their aroma.
No cayenne? Use red pepper flakes at half the amount. Out of mustard powder? Dry mustard works the same. If you prefer less heat, cut the cayenne in half and add more black pepper. For a smokier profile, swap regular paprika for Spanish smoked paprika. The blend is forgiving—taste as you go and adjust.
Store in an airtight container away from light and heat. Keeps its potency for 6-12 months. For best results, make a large batch—this blend disappears fast once you start using it on everything from shrimp to roasted potatoes.

Step-by-Step Instructions for Seafood Boil Seasoning
Combine these spices in the right order for maximum flavor impact.
Step 1: Combine the Dry Spices
In a medium bowl, add the 3 tbsp Paprika, 2 tbsp Garlic Powder, and 2 tbsp Onion Powder. These form the aromatic foundation of your blend. I use a fork to break up any clumps in the powders, ensuring an even distribution throughout the mix.
The garlic and onion powders provide deep, savory notes, while the paprika adds both color and a subtle sweetness. Mix these three ingredients thoroughly until no streaks of individual spices remain visible.
Step 2: Incorporate the Herbs and Heat
Add the 1 tbsp Dried Thyme, 1 tbsp Dried Oregano, and 1 tbsp Cayenne Pepper to the bowl. I always rub the dried thyme and oregano between my fingers as I add them—this releases their essential oils and intensifies their flavor.
The cayenne brings the heat, so adjust carefully if you prefer a milder blend. Stir these additions into the existing mixture until fully combined. You should start seeing a vibrant, reddish-brown color developing as the paprika and cayenne blend with the other spices.
Step 3: Add the Finishing Touches
Now incorporate the 1 tbsp Black Pepper, 1 tbsp Mustard Powder, and 2 tbsp Sea Salt. The black pepper adds sharpness, while the mustard powder contributes a subtle tang that balances the richness of the other spices.
The sea salt not only seasons but also helps to draw out the flavors of the other ingredients. Mix everything together for at least 1 full minute to ensure complete integration. The final blend should be uniform in color and texture, with no visible separation between components.
Step 4: Add and Store the Bay Leaves
Place the 4 pieces Bay Leaves into the spice mixture. I recommend crushing them slightly with your fingers before adding—this helps release their aromatic compounds. Gently fold them into the blend so they’re evenly distributed without breaking them into tiny pieces.
Transfer the completed seasoning to an airtight container. Store in a cool, dark place for up to 3 months to preserve freshness. The bay leaves will continue to infuse the blend with their earthy, floral notes over time, deepening the flavor with each use.
Pro Tips For Making Seafood Boil Seasoning
- Toast the Spices: Lightly toast the paprika, thyme, and oregano in a dry pan for 30 seconds—it wakes up the flavors and makes the seasoning taste fresher than straight from the jar.
- Double the Garlic: I learned this the hard way—garlic powder mellows in the boil, so use twice what you think you need, especially if cooking for a crowd.
- Skip the Salt Early: Resist the urge to add salt to the seasoning mix upfront—seafood releases its own brine, and you can always adjust at the end.
- Grind the Dried Herbs: Sounds weird, but it works: pulse the dried thyme and oregano in a spice grinder for a finer texture so they distribute evenly and don’t settle at the bottom.
Best Sauces and Condiments for Seafood Boil Seasoning
Classic Remoulade
This creamy sauce is my go-to for seafood boils. I whisk together ½ cup mayonnaise, 2 tbsp ketchup, and 1 tbsp prepared horseradish with 1 tsp of this seasoning blend. It adds just the right kick to complement the spices. 💫
Lemon-Garlic Butter
Melt ½ cup unsalted butter with 3 minced garlic cloves and zest of 1 lemon. Stir in 1 tsp of your seasoning for a quick dipping sauce. David always asks for extra of this—it’s his favorite with shrimp.
Cajun Aioli
Blend ¾ cup mayonnaise with 1 tbsp lemon juice and 1 tsp of the spice mix. I add 1 pressed garlic clove for extra punch. This works beautifully as a spread for garlic bread to serve alongside your boil.
Spicy Cocktail Sauce
Elevate store-bought cocktail sauce by mixing in ½ tsp of your seasoning per ¼ cup sauce. The paprika and cayenne add depth that pairs perfectly with chilled seafood. I always keep a batch in the fridge during summer.
Buttermilk Ranch
Combine ½ cup buttermilk, ¼ cup mayonnaise, and 1 tbsp chopped fresh dill. Add ½ tsp of the blend and a pinch of sea salt from the recipe. It’s a refreshing contrast to the bold boil flavors.
Quick Mop Sauce
Simmer 1 cup apple cider vinegar with 2 tbsp brown sugar and 1 tbsp of your seasoning for 5 minutes. This tangy sauce is perfect for brushing on corn or potatoes during the boil. 🔥
