Ruth's Chris lobster mac and cheese features creamy cheese sauce and generous lobster chunks
Ruth's Chris Steak House built its reputation on premium steaks but their lobster mac and cheese stands as a menu superstar. The dish combines sweet Maine lobster with ultra-creamy cheese sauce and perfectly cooked pasta. Cheeses melt into heavy cream and butter creating a velvety base that coats every noodle.
Each serving contains visible lobster pieces throughout not just sprinkled on top. The kitchen folds fresh lobster meat gently into hot pasta to prevent toughening. The cheese sauce uses Gruyère for nuttiness, sharp cheddar for tang, and Parmesan for saltiness. Heavy cream and whole milk create signature richness.
What makes it restaurant-quality
Three factors separate this from standard recipes: lobster quantity, cheese blend, and baking technique. Ruth's Chris loads each serving with substantial lobster pieces not mere flakes. The cheese sauce incorporates Gruyère, sharp cheddar, and Parmesan for complex flavor. A final oven bake creates a golden crust while keeping interior creamy.
- Lobster meat: 1 pound per 4 servings minimum
- Cheese trio: Gruyère, sharp cheddar, Parmesan
- Texture contrast: Creamy interior, crispy top layer
- Pasta choice: Elbow macaroni or cavatappi
- Baking temp: 375F for 20-25 minutes
Signature flavor profile
The sauce starts with a roux base then builds through careful temperature control. Sweet lobster meat balances the rich sharpness of aged cheeses. A hint of garlic and subtle white pepper enhance without overpowering. The final dish emerges from the oven bubbling with a lightly browned cheese crown.
Texture | Creamy interior, crispy top |
|---|---|
Flavor | Rich, sweet, savory |
Key ingredient | Fresh lobster meat |
Customers order this as a side or main course. Copycat recipes replicate that signature richness using similar cheese ratios and baking methods. Success depends on not skimping on lobster or cheese quality. Home cooks should use fresh lobster and avoid pre-shredded cheese with anti-caking agents.
Gather lobster meat, elbow pasta, three cheeses, heavy cream, and butter

Gruyère, sharp cheddar, and Parmesan create signature depth. Heavy cream and butter build richness. Whole milk thins sauce without diluting flavor. All-purpose flour forms roux base. Basic seasonings include salt, white pepper, garlic powder.

Equipment checklist
Large stock pot for pasta. Medium heavy-bottomed saucepan for sauce. Whisk prevents lumps. 9x13 inch baking dish. Cheese grater. Colander. Measuring tools. Rubber spatula folds gently.
Prep ingredients before starting. Shred cheese while oven preheats. Chop lobster into bite-size chunks. Measure liquids and seasonings. This mise en place ensures smooth cooking.
Cook pasta al dente and prep lobster meat while oven heats to 375F
Turn oven to 375F. Move rack to center. Start heating now.
Grab large stock pot. Fill with 4 quarts water. Add 2 tablespoons kosher salt. Crank heat to high. Wait for rolling boil.
Dump in pasta. Stir like crazy first 30 seconds. Cook 2 minutes less than package minimum. Bite a piece. Should resist slightly. Center shows thin white line. That's perfect al dente. Scoop out 1 cup pasta water. Drain rest in colander. Shake hard. Never rinse. You need that starch.
While water heats, prep lobster. Lay meat on cutting board. Chop into 1/2 inch cubes. Check each piece twice for shell fragments. Missed shells crack teeth. Pat everything bone-dry with paper towels. Wet lobster makes watery sauce. Toss in bowl. Set aside.
Using whole lobsters? Crack tails and claws. Pull meat in one piece if possible. Save shells for seafood stock later.
Timing sync
Step | Time needed | Start when |
|---|---|---|
Oven preheat | 12-15 min | Immediately |
Water boil | 8-10 min | After oven starts |
Pasta cooking | 8-10 min | Water boils |
Lobster prep | 5-7 min | While pasta cooks |
Make-or-break tips
- Cook pasta 2 minutes under. It soaks sauce and bakes more.
- Reserved water is liquid gold. Fixes any sauce thickness.
- Dry lobster obsessively. Paper towels are your friend.
- Move fast after draining. Cold pasta clumps and won't coat.
- Salting pasta water is non-negotiable. Only chance to season inside.
Make cheese sauce on stovetop then fold in pasta and lobster pieces
Melt butter in heavy saucepan over medium heat. Add flour. Whisk constantly 2 minutes. No browning. Raw flour tastes awful. Slowly pour cream and milk. Whisk like mad. No lumps. Simmer gently 5-7 minutes. Sauce coats spoon.
Pull pan off heat. Add cheese handful by handful. Stir each until melted. Never boil cheese. It turns grainy. Season with salt, white pepper, nutmeg. Taste. Adjust.
Fold in pasta with rubber spatula. Lift and turn gently. Coat every noodle. Add reserved pasta water if needed. Sauce should be loose. It thickens as it bakes.
Add lobster last. Fold 2-3 times max. Over-mixing toughens meat. Work fast. Scrape into baking dish. Level top.
Temperature control
- Medium-low heat only
- Never exceed 180F after cheese
- Keep sauce moving
Mistakes that ruin it
- Dumping cheese fast = clumps
- Boiling after cheese = oily mess
- Over-folding = mushy pasta
- Adding lobster early = rubber
Step | Time | Warning |
|---|---|---|
Roux | 2 min | Don't brown |
Liquids | 5-7 min | No boiling |
Cheese | 3 min | Off heat |
Pasta | 2 min | Gentle folds |
Lobster | 30 sec | Last step |
Transfer to baking dish and bake until golden brown on top
Scrape mixture into buttered 9x13 baking dish. Spread evenly. Don't pack down. You want air pockets for browning.
Sprinkle panko breadcrumbs over top. Add extra Parmesan. Drizzle melted butter. This creates crust.
Slide into center rack. Close door. Set timer 20 minutes. Check at 15. Top should bubble around edges. Center puffs slightly. Color turns deep golden. Cheese spots brown. That's perfect.
Overbaking dries interior. Underbaking leaves pale top. Trust visual cues not clock.
