Copycat Red Lobster Cajun Seasoning (5-Minute Homemade Blend)

If you’ve ever ordered the Cajun chicken linguine or a skewer of Cajun-grilled shrimp at Red Lobster and thought, “I need this flavor at home,” you’re in the right place. This copycat Red Lobster Cajun seasoning comes together in about five minutes with ten spices you almost certainly already have in your pantry — and once you mix up a jar, you’ll find yourself shaking it onto everything from salmon fillets to popcorn.

What makes Red Lobster’s version stand out from a standard store-bought Cajun blend is balance. It leans warm and savory rather than scorching, with a paprika-and-garlic backbone, a gentle cayenne kick, and an earthy undertone that keeps it interesting. Think of it as sitting somewhere between a classic Louisiana Cajun seasoning and a seafood boil spice — bold enough for blackening, mild enough that the whole family will eat it.

If you love recreating Red Lobster favorites at home, this seasoning is the perfect companion to my Copycat Red Lobster Shrimp Scampi, Red Lobster Cheddar Bay Biscuits in the Air Fryer, and Copycat Red Lobster Coconut Shrimp — put them all together and you’ve basically got the whole menu covered.

Best of all? Making it yourself costs a fraction of a bottled blend, contains zero anti-caking agents or fillers, and lets you control the salt and the heat.

Why You’ll Love This Recipe

It’s ready in 5 minutes flat. Measure, whisk, done. No cooking, no equipment beyond a bowl and a jar.

It tastes remarkably close to the restaurant. The paprika-forward, medium-heat profile is what gives Red Lobster’s Cajun dishes their signature warmth without setting your mouth on fire.

It’s endlessly versatile. Seafood is the obvious move, but this blend is just as good on chicken thighs, roasted potatoes, corn on the cob, and eggs.

You control everything. Want it spicier? Add cayenne. Watching sodium? Cut the salt in half or leave it out entirely — the flavor holds up beautifully.

It’s air fryer gold. Because this is a dry rub with no sugar to burn, it’s ideal for high-heat air fryer cooking — think Air Fryer Cajun Shrimp or Air Fryer Blackened Salmon. More on that below.

Ingredients for Copycat Red Lobster Cajun Seasoning

Here’s everything you need — all standard spice-rack staples:

• Paprika: The foundation of the blend. It brings color, sweetness, and body. Use regular sweet paprika for the closest match, or swap in smoked paprika for a deeper, grill-kissed flavor.
• Garlic powder: Savory depth that ties everything together.
• Onion powder: A mellow, slightly sweet counterpoint to the garlic.
• Cayenne pepper: The heat. This amount lands at a family-friendly medium; adjust up or down freely.
• Fine sea salt: Seasons the blend so it’s ready to use straight from the jar.
• Freshly ground black pepper: Sharp, piney bite.
• Ground cumin: The subtle earthy note that makes people ask, “What is that?”
• Ground mustard: A whisper of tang and sharpness that brightens seafood especially.
• Dried oregano: Herbal lift.
• Dried thyme: Classic Cajun herb; a little goes a long way.

Yield: About ½ cup of seasoning — enough for roughly 8–10 pounds of protein.

Whisk. Stir thoroughly with a small whisk or fork until the color is completely uniform and no streaks of paprika or cayenne remain.

How to Make It

Step 1: Add all ten spices to a small mixing bowl.

Step 2: For a finer, more restaurant-style texture that clings evenly to shrimp and fish, pulse the mixture a few times in a spice grinder or crush it briefly with a mortar and pestle. This also wakes up the dried herbs.

Step 3: Transfer to an airtight jar, label it with the date, and keep it in a cool, dark cabinet.

That’s the whole recipe. Seriously.

How to Use This Cajun Seasoning

This is where the jar earns its keep. A good rule of thumb: about 1 tablespoon of seasoning per pound of protein for a medium coating, or up to 1½ tablespoons for true blackening.

• Cajun shrimp: Toss a pound of peeled shrimp with a tablespoon of olive oil and a tablespoon of this blend, then follow the timing in my Air Fryer Cajun Shrimp — 400°F for 6–8 minutes, shaking halfway. Starting from a frozen bag? My guide to Air Fryer Frozen Shrimp has you covered, no thawing required. For a Forrest Gump-worthy spread, shake it over my Air Fryer Bubba Gump Shrimp too.
• Blackened salmon or white fish: Pat fillets dry, brush with melted butter, and coat generously — this blend slides right into my Air Fryer Blackened Salmon in place of the blackening mix. It’s also fantastic on flaky white fish like my Air Fryer Cajun Snapper, and if your fillets are still in the freezer, use the two-stage method from my Frozen Salmon in the Air Fryer guide so the seasoning actually sticks.
• Cajun chicken: Rub onto boneless thighs or breasts before grilling, baking, or air frying. It’s the fast track to a copycat Cajun chicken pasta at home.
• Vegetables and sides: Sprinkle over potato wedges, corn on the cob, roasted broccoli, or French fries. A dusting over my Red Lobster Crabby Cheese Fries takes an already indulgent appetizer completely over the top.
• Beyond dinner: Stir a teaspoon into mayo for a quick remoulade-style spread (or start with my Red Lobster Tartar Sauce and add a pinch for a Cajun twist), dust it over popcorn, or rim a Bloody Mary glass.

Air Fryer Tip

Dry spice blends like this one are perfect for the air fryer because there’s no sugar to scorch at high temperatures. For the best crust, lightly oil your protein first, then apply the seasoning — the oil helps the spices bloom and adhere instead of blowing around the basket. If your air fryer runs hot, check seafood a minute or two early; cayenne and paprika can darken quickly past 400°F.

Recipe Variations

• Milder: Reduce cayenne to ½ teaspoon. You’ll keep all the flavor with barely a tingle of heat.
• Hotter: Bump cayenne to 1 tablespoon and add ½ teaspoon of red pepper flakes for texture and pop.
• Smoky: Replace the sweet paprika with smoked paprika and add ¼ teaspoon of chipotle powder.
• Salt-free: Simply omit the salt. This turns the blend into a pure spice mix you can use liberally on low-sodium diets — season with salt separately at the table.
• Extra herby (Creole-style): Add ½ teaspoon of dried basil and a pinch of celery seed for a blend that leans toward New Orleans Creole seasoning.

Storage

Stored in an airtight container away from heat and light, this blend stays at peak flavor for about 6 months and remains safe to use well beyond that — it just gradually loses punch. Give the jar a shake before each use, since finer particles settle. If you cook Cajun dishes often, double or triple the batch; the ratios scale perfectly.

Pro tip: Never shake the jar directly over a steaming pot. Moisture creeping into the jar is the number-one cause of clumpy, stale spice blends. Spoon it out instead.

What Does Red Lobster’s Cajun Seasoning Taste Like?

If you’ve never had it, picture a cross between a seafood boil seasoning and a traditional Louisiana Cajun rub. It’s warm rather than fiery, savory from garlic and onion, slightly earthy from cumin, and finishes with a soft herbal note from the thyme and oregano. It was built for seafood, which is why it never overpowers delicate shrimp or flaky fish — but that same restraint is exactly what makes it so good on everything else.

Frequently Asked Questions

Is this the actual Red Lobster recipe? No — Red Lobster doesn’t publish its spice formulas. This is a homemade copycat blend developed to closely match the flavor profile of their Cajun dishes using common pantry spices.

What’s the difference between Cajun and Creole seasoning? They overlap heavily, but Cajun blends are typically more pepper-forward and rustic, while Creole blends lean more herbal, often featuring basil and celery seed. This recipe sits firmly in Cajun territory with a hint of herb.

Can I use this in place of Old Bay? In most recipes, yes. Old Bay is heavier on celery salt and warm baking-spice notes, while this blend is more garlicky and peppery — but for shrimp, crab cakes, and fries, they’re happily interchangeable. It even works in the crab filling for my Copycat Red Lobster Stuffed Mushrooms if you want a spicier spin.

How much should I use per pound of meat? Start with 1 tablespoon per pound for a medium coating. For blackening, go up to 1½ tablespoons and make sure your pan (or air fryer) is fully preheated.

Is this seasoning gluten-free and keto-friendly? Yes. It’s nothing but pure ground spices and herbs — no flour, sugar, or fillers — so it fits gluten-free, keto, paleo, and Whole30 cooking.

My blend clumped up. Can I save it? Usually. Break up the clumps with a fork or pulse briefly in a spice grinder. To prevent it next time, keep the jar tightly sealed, store it away from the stove, and never shake it over steam.

Make It a Red Lobster Night at Home
