Fleming's Lobster Mac and Cheese Recipe (Copycat)

Fleming's lobster mac and cheese copycat recipe recreates the steakhouse favorite using chipotle cheddar sauce and cavatappi pasta.

Chef Brandon Powell's original side dish features smoked cheddar, heavy cream, and chipotle heat that cuts through the richness.

Upgrade the side to an entree by adding parboiled lobster meat from a two-pound live lobster.

The dish delivers three distinct textures: crunchy chipotle panko topping, creamy cheese sauce, and tender shellfish.

Key ingredients include fresh-grated smoked cheddar, room temperature dairy, and curly corkscrew pasta that traps sauce better than elbows.

Build a blonde roux with butter and onion, whisk in cream and half-and-half, then melt cheese off heat to prevent graininess.

Fold al dente pasta and lobster chunks into the sauce, top with spicy breadcrumbs, and bake until golden.

Serve immediately with Sauvignon Blanc or alongside prime beef for the full steakhouse experience.

Fleming's lobster mac and cheese combines chipotle cheddar sauce with buttery lobster for a steakhouse side dish turned entree.

The Steakhouse Original

Fleming's Prime Steakhouse built their reputation on aged beef but regulars know the chipotle cheddar mac and cheese steals the show. Chef Partner Brandon Powell created this side dish using cavatappi pasta - curly corkscrew tubes that trap sauce better than elbows. The base combines smoked cheddar with heavy cream and chipotle chili powder for subtle heat that cuts through the richness.

From Side to Center Plate

The menu lists this as a side with an optional lobster upcharge. At home, skip the upcharge and add a whole 2-pound lobster. Parboil for nine minutes, shock in ice water, then extract meat from the claws and tail. Cut into bite-sized chunks and fold into the pasta before the final bake. One lobster yields 4-6 ounces of meat - enough protein to transform this into a main course.

Texture and Heat

The chipotle appears twice: in the creamy sauce and in the topping. Panko breadcrumbs toast in chipotle-infused oil until crisp. This creates a three-layer bite - crunchy topping, creamy pasta, and tender lobster. The smoke from the cheddar and chipotle complements the sweet shellfish better than standard cheddar alone. While Capital Grille uses truffle oil and Ruth's Chris keeps it classic, Fleming's Southwest heat signature stands apart.

Gather cavatappi pasta, smoked cheddar, heavy cream, and fresh lobster meat for this luxury comfort food recipe.

Pasta Selection

Cavatappi corkscrews trap sauce better than elbows. Use 1 pound dry. Cook 8-9 minutes until slightly firm. Cool under running water and toss with corn oil to prevent sticking. No cavatappi? Cellentani or gemelli work. Avoid thin pasta that breaks under heavy sauce.

Cheese Blend

Smoked cheddar delivers the signature flavor. You need 3/4 pound grated smoked cheddar plus 4 ounces sharp cheddar for depth. Pre-grated bags contain anti-caking agents that ruin texture. Grate blocks fresh. The smoke level varies by brand - applewood or hickory both work.

Dairy Base

Heavy cream (2 cups) and half-and-half (3 cups) create the velvety base. Do not substitute milk - the fat content matters for sauce stability. Bring to room temperature before adding to roux to prevent curdling.

Lobster Specifications

One 2-pound live lobster yields 4-6 ounces meat. Frozen tails work in pinch - thaw overnight in fridge. Cut meat into 1-inch chunks. For a simpler version, use 8 ounces pre-cooked claw meat from fish counter.

Aromatics and Thickeners

Butter (4 oz), diced onion (6 oz), and flour (3 tbsp) build the roux. Yellow onion works better than sweet - you want savory depth not sugar. Chipotle powder (1 tsp) goes into both the sauce and the breadcrumb topping. Corn oil (1 tbsp) toasts the panko with the spice.

Quality matters here. This award-winning approach demands fresh blocks of cheese and live lobster if possible. Frozen works but never use pre-shredded cheese bags.

Build a roux with butter and flour before adding cream, cheese, and spices to create the signature sauce base.

Roux Foundation

Melt 4 ounces lightly salted butter in a large sauce pot over medium-high heat. Add 6 ounces of half-inch diced onions. Sauté 4 to 5 minutes until translucent but not caramelized. The onions provide savory backbone that cuts the richness of the dairy.

Sprinkle 3 tablespoons all-purpose flour over the butter and onions. Stir constantly for 1 to 2 minutes. The raw flour taste must cook out but do not let it brown. You want a blonde roux for this white sauce base. If the roux darkens past peanut butter color, the sauce turns muddy and loses the bright orange hue from the cheddar.

Dairy Integration

Gradually whisk in 2 cups heavy cream and 3 cups half-and-half. Room temperature dairy prevents temperature shock and lumps. Add 2 teaspoons kosher salt and 1 teaspoon finely ground white pepper. Black pepper works in a pinch but white keeps the sauce color clean and adds subtle heat without visible specks.

Bring the mixture to a gentle simmer, not a rolling boil. Cook 5 to 6 minutes until the sauce coats the back of a spoon and holds a line when you drag your finger through it. The consistency should resemble heavy pancake batter. Too thin and the pasta swims. Too thick and it bakes up dry and pasty.

Cheese Melting

Remove pot from heat before adding cheese. Grate 12 ounces smoked cheddar and 4 ounces sharp cheddar fresh from blocks. Pre-grated bags contain cellulose that prevents smooth melting and creates graininess. Add handfuls to the hot liquid, stirring vigorously between each addition until fully incorporated.

The residual heat melts the cheese without breaking the emulsion. If the sauce cools too much before all cheese is added, return to low heat briefly. Never boil after adding cheese or the proteins seize and separate. The final sauce should be glossy and pourable, not stringy or clumped.

Fold cooked pasta and parboiled lobster into the sauce, then top with chipotle panko breadcrumbs before baking.

Pasta Integration

Add the cooled cavatappi directly to the cheese pot. Stir vigorously to coat every curve. The pasta should be slightly firm from the 8-minute boil - it finishes cooking in the oven. If the pasta sits too long before mixing, the oil coating prevents sauce adhesion. Work quickly while both components are warm.

Lobster Incorporation

Cut the parboiled lobster meat into 1-inch chunks. Fold gently into the mac and cheese mixture. Do not over-stir or the delicate protein shreds. The lobster stays barely cooked at this stage - it finishes in the 350-degree oven without turning rubbery. For a faster version, use pre-cooked claw meat added in the last 2 minutes of mixing.

Assembly

Transfer the mixture to individual baking crocks or a 12-by-9-inch baking dish. Spread evenly but do not pack down. Leave some texture on top for the breadcrumbs to grip. The dish should fill 3/4 full to prevent overflow during bubbling.

Chipotle Panko Topping

Heat 1 tablespoon corn oil in a sauté pan over medium-high heat. Add 1 teaspoon chipotle chili powder. Heat 30 seconds until the oil smokes and the spice blooms. Remove immediately from heat and stir in 3/4 cup panko breadcrumbs. The residual heat toasts the crumbs in seconds. Work fast - the oil cools quickly and the crumbs must absorb the spicy fat.

Sprinkle the chipotle panko evenly over the pasta surface. Do not mix in - the contrast between creamy base and crunchy lid defines the texture. For extra heat, add a pinch of cayenne to the panko.

Bake until the top turns golden brown and crisp. The edges bubble and the center reaches 165°F. Let rest 5 minutes before serving. This baked approach creates the signature Fleming's texture better than stovetop-only methods.

Serve this decadent mac and cheese immediately with a crisp white wine or as a steak accompaniment.

Immediate Service

Rest the dish exactly 5 minutes after removing from the oven. This sets the sauce and prevents burned mouths. Serve in the same baking crocks or transfer to warm plates. The contrast between the hot interior and crisp topping disappears quickly - do not let it sit longer than 10 minutes before serving.

Wine Pairings

The chipotle heat and rich cheese demand acidity. Pour Sauvignon Blanc from New Zealand or Sancerre. Unoaked Chardonnay from Chablis cuts the fat without adding woody flavors. For red drinkers, choose a light Pinot Noir from Oregon or Burgundy - heavy tannins clash with the dairy. Champagne or sparkling wine works surprisingly well; the bubbles scrub the palate between bites.

Steak Combinations

Fleming's built their reputation on prime beef. Pair this mac and cheese with a 6-ounce filet mignon for the classic steakhouse experience. The richness of the pasta balances lean beef. For heartier appetites, serve alongside a 12-ounce ribeye. The rendered fat from the steak complements the lobster sweetness. Do not serve with heavily sauced steaks - the mac and cheese provides enough flavor complexity.

Portion Control

The full recipe serves 5 as a side or 3 as an entree. For a date night version, halve all ingredients and use an 8-inch baking dish. Reduce bake time to 12 minutes.

Leftover Protocol

Refrigerate within 2 hours in airtight containers. The sauce breaks when frozen - do not freeze. Reheat in a 325°F oven covered with foil for 15 minutes, not the microwave. The lobster turns rubbery when microwaved. Add a splash of cream when reheating to restore moisture. Consume within 48 hours for food safety and optimal texture.
