Lobster Casserole
intro
Creamy, briny fresh lobster baked under a crisp buttery cracker crust, a beloved coastal comfort dish perfect for warm summer family gatherings.
Ingredients
Steps
Preheat and Prep Dish
Preheat your oven to 375°F (190°C). Use 1 tbsp of the unsalted butter to generously grease the interior bottom and sides of the 9x13 inch clear tempered glass baking dish to prevent sticking. Set the prepared dish in its central spot on the counter, near where you will mix the lobster filling.
Make Creamy Cheese Sauce
Melt 3 tbsp of the unsalted butter in the 1.5 quart polished stainless steel saucepan over medium-low heat. Whisk in the all-purpose flour to form a smooth, pale golden roux, cooking for 2 minutes until it smells faintly nutty with no raw flour aroma. Slowly stream in the whole milk and heavy cream while whisking constantly to avoid lumps, then stir in the dry sherry. Simmer for 3-4 minutes, stirring with the matte pale gray silicone spatula, until the sauce thickens enough to coat the back of the spatula (a finger drawn through the sauce leaves a clean line that does not run). Stir in 1/4 tsp kosher salt, 1/4 tsp black pepper, and the freshly grated sharp white cheddar until fully melted and smooth, then remove the pan from heat.
Toss Lobster in Sauce
Place the large chunks of cooked lobster meat into the medium brushed stainless steel mixing bowl. Pour the warm cheese sauce over the lobster, then gently fold with the silicone spatula to coat every chunk evenly. Take care not to break the lobster into tiny pieces – aim to keep 1-2 inch bite-sized chunks for the best texture. Stir in 1 tbsp of the chopped parsley.
Mix Crumble Topping
Melt the remaining 2 tbsp of unsalted butter. Place the coarsely crushed buttery crackers in one of the small clear glass prep bowls, pour the melted butter over the crumbs, then add the remaining 3/4 tsp kosher salt, 1/4 tsp black pepper, and smoked paprika. Use the stainless steel pastry blender to toss the crumbs until evenly coated in butter, leaving some larger pea-sized crumb pieces intact for extra crunch.
Assemble Casserole Layers
Pour the entire lobster and sauce mixture into the greased 9x13 inch glass baking dish, spreading it into a smooth, even layer with the silicone spatula. Sprinkle the buttered cracker crumb topping evenly over the entire surface, covering all exposed sauce, but do not press the crumbs down firmly (pressing will make the topping soggy as it bakes).
Bake Until Golden Bubbly
Place the assembled casserole on the middle rack of the preheated 375°F (190°C) oven. Bake for 25-30 minutes, until the sauce bubbles vigorously around the edges of the dish and the cracker topping is deep golden brown. If the topping browns too quickly before the sauce is bubbly, tent a loose piece of aluminum foil over the top for the last 10 minutes of baking. Remove from the oven and let rest 5 minutes to allow the sauce to set slightly.
Garnish and Serve
Sprinkle the remaining 1 tbsp of chopped fresh parsley and a light pinch of extra paprika over the warm casserole for bright color. Use the large stainless steel serving spoon to scoop generous 1.5 cup portions onto the off-white matte ceramic dinner plates, pairing each serving with a lemon wedge in a small glass ramekin for squeezing over top. Serve immediately while the topping is crisp and the sauce is hot.
Tips
2.Crush crackers by hand for the topping instead of using a food processor: a food processor creates uniformly fine crumbs that turn soggy under melted butter, while hand-crushed, uneven coarse and fine crumbs bake into a perfectly crisp, crunchy topping.
3.Grate cheddar fresh for the sauce: pre-shredded store-bought cheddar is coated in potato starch to prevent caking, which makes the finished sauce grainy. Freshly grated cheese melts seamlessly into a silky, smooth cream sauce.

SO good! I made this for my partner’s birthday dinner and he said it tasted just like the lobster casserole his grandma used to make at their Cape Cod summer house. I was nervous because I’ve never made any kind of seafood casserole before (medium difficulty had me sweating a little tbh) but the steps were super straightforward, no fancy weird ingredients needed. Will absolutely be adding this to my regular meal rotation!
Quick question — can I use frozen lobster meat for this instead of fresh? My grocery store was out of fresh tails this week and I really want to make this for my poker night this weekend. Looks absolutely incredible, the cheese topping in the photo has me drooling!
Game. Changer. I brought this to my office potluck last week and people were literally coming up to me for the recipe before we even finished serving. The only tweak I made was adding a handful of buttery Ritz cracker crumbs to the top for extra crunch, and *chef’s kiss*. So creamy, so much lobster flavor, no weird filler that takes away from the star of the show. Worth every penny for the lobster meat, fr
Made this last night for dinner and my whole family devoured it! Even my super picky 7 year old who says he “hates fish” ate two whole servings. I will say it took me a little closer to 45 minutes total because I prepped the lobster meat myself, but that’s on me, not the recipe. So rich and flavorful, not at all fishy tasting like some seafood bakes I’ve tried before.
Wait has anyone tried making this ahead for meal prep? I’m trying to get a jump on next week’s dinners and this looks perfect, but I’m worried the creamy sauce will separate if I refrigerate it for a couple days before baking. Any tips?
OMG I cannot believe how easy this was for how fancy it tastes! I made this for my book club dinner party and everyone thought I spent hours in the kitchen, little did they know it only took 35 minutes in the oven. I paired it with a simple arugula salad and some crusty garlic bread to soak up all that extra creamy sauce, and it was a match made in heaven. Will 100% be making this again for Thanksgiving as a fancy side!
