I developed this recipe after years of craving that signature Longhorn flavor. The secret lies in building layers of flavor through a slow simmer with fresh seafood and a velvety broth. It’s simpler to make than you might expect.

Perfect for special occasions or when you need a taste of your favorite steakhouse at home. This chowder delivers on its promise of authentic Longhorn quality.

Ingredients for Shrimp and Lobster Chowder Longhorn

Rich seafood meets creamy comfort in this indulgent, restaurant-worthy chowder with shrimp and lobster.

The seafood is the star here. Fresh lobster meat from the seafood counter at Whole Foods or Trader Joe’s is ideal (pre-cooked for convenience). For shrimp, wild-caught when possible—look for firm, translucent flesh with no fishy odor. The seafood stock should be high-quality (I like Better Than Bouillon seafood base) for that deep, oceanic flavor Longhorn achieves.

Out of lobster? Extra shrimp or scallops work great—just keep the total seafood weight the same. No seafood stock? Clam juice plus chicken broth gets you close. Dried thyme can be swapped for one-third the amount of fresh. Old Bay is non-negotiable for that signature taste, but a pinch of celery salt plus paprika in a bind works too.

Chowder tastes even better the next day once flavors meld. Stores in the fridge for 3-4 days, freezes for 2-3 months. Reheat gently on the stove—don’t boil, or the cream may separate.

Step-by-Step Instructions for Shrimp and Lobster Chowder

Here’s how I recreate that rich, creamy Longhorn classic in your own kitchen.

Step 1: Sauté the Aromatic Base

Melt 4 tbsp Unsalted Butter in a large Dutch oven over medium heat. Add the finely diced Yellow Onion and Celery Stalks, cooking for 5-6 minutes until the vegetables soften and become translucent. The onion should smell sweet and fragrant, not sharp.

Add the minced Garlic Cloves and cook for 30 seconds until just fragrant. Don’t let it brown—garlic burns quickly. This aromatic trio forms the flavor foundation for your chowder, so take your time here.

Step 2: Build the Roux and Add Potatoes

Whisk in the 0.5 cup All-Purpose Flour to create a roux. Cook for 2-3 minutes, stirring constantly, until the mixture turns a light golden color. This cook time removes the raw flour taste and builds depth.

Gradually pour in the 4 cups Seafood Stock while whisking continuously to prevent lumps. Add the diced Russet Potatoes, 1 tbsp Old Bay Seasoning, 1 tsp Dried Thyme, 1.5 tsp Salt, and 0.5 tsp Black Pepper. Bring to a simmer and cook for 10-12 minutes until potatoes are tender when pierced with a fork.

Step 3: Add Dairy and Seafood

Reduce heat to low and stir in the 2 cups Heavy Cream and 1 cup Whole Milk. I always use full-fat dairy here—it’s the secret to that luxurious Longhorn texture. Let the mixture simmer gently for 5 minutes to meld the flavors.

Add the 1 lb Lobster Meat and 1 lb Large Shrimp. Cook for 3-4 minutes just until the shrimp turn pink and opaque. Be careful not to overcook the seafood—it should be tender and just cooked through. The lobster is already cooked, so it just needs to heat through.

Step 4: Finish and Serve

Stir in the remaining 2 tbsp Unsalted Butter for extra richness. Taste and adjust seasoning if needed—though the Old Bay should provide plenty of flavor. The chowder should be thick enough to coat the back of a spoon but still pourable.

Let it sit off heat for 5 minutes to allow the flavors to fully develop. The consistency will thicken slightly as it cools. Serve hot in bowls, garnished with a sprinkle of Old Bay if desired. This copycat version captures that signature creamy indulgence you love from Longhorn.

Creative Variations of shrimp and lobster chowder longhorn

New England Style

Swap the seafood stock for clam juice and add ½ tsp dried tarragon along with the thyme. This gives a classic New England chowder profile. I also add 1 diced carrot with the potatoes for extra sweetness and color. 🗺️

Spicy Cajun Kick

Add 1 tsp cayenne pepper and 1 tbsp Cajun seasoning with the Old Bay. Use Andouille sausage in place of half the shrimp for a Louisiana-style twist. The heat builds beautifully against the creamy base.

Lighter Version

Replace the heavy cream with 1 cup half-and-half and 1 cup whole milk. Use 2 tbsp cornstarch mixed with 2 tbsp water instead of flour for thickening. This cuts calories while keeping the chowder rich and satisfying.

Smoked Seafood

Use smoked lobster meat and smoked shrimp for a deep, wood-fired flavor. I find this at specialty seafood counters. Add ½ tsp smoked paprika to enhance the smokiness. This variation feels like a gourmet upgrade. 🔥

Corn and Bacon

Add 1 cup fresh corn kernels with the potatoes and 4 slices cooked bacon, crumbled, at the end. The sweetness of corn and saltiness of bacon create a perfect balance with the seafood.

Herb Garden

Stir in 2 tbsp fresh parsley, 1 tbsp fresh chives, and 1 tsp fresh dill at the end. This brightens the dish with fresh herbal notes. I love this version in spring when herbs are at their peak.
