How to Make Ruth’s Chris Lobster Mac and Cheese Copycat Recipe
Step 1: Pre-cook Your Pasta
Ensure that your macaroni is cooked to al dente. Follow the package instructions carefully, then drain and set aside. I usually add a little olive oil to prevent the pasta from sticking together.
Step 2: Cook and Prep the Lobster Tails
Boil or steam your lobster tails until they reach that beautiful, bright red color. It usually takes about 8-10 minutes, depending on the size of the tails. Once cooked, let them cool slightly, then chop the lobster meat into bite-sized pieces.
Step 3: Make the Roux
In a large saucepan, melt the butter over medium heat. Once it’s completely melted, whisk in the all-purpose flour until it forms a smooth, golden paste. This is your roux and it will be the thickening backbone for your cheese sauce.
Step 4: Add the Milk to the Roux
Slowly whisk in the whole milk. This step is crucial as it prevents the sauce from getting lumpy. Keep whisking until the mixture is smooth and starts to thicken.
Step 5: Add Seasonings
Now, add the garlic powder, salt, and pepper. If you’re feeling adventurous, sprinkle in the mustard powder and nutmeg. These optional spices heighten the flavor profile of the dish.
Step 6: Incorporate the Cheeses
Gradually add the shredded cheddar cheese, parmesan, and gruyere cheese to the milk mixture. Whisk continuously until all the cheese has melted and the sauce is smooth and creamy.
Step 7: Combine Pasta and Cheese Sauce
Add the cooked macaroni to the cheese sauce. Stir well to ensure that every noodle is coated with the cheesy goodness.
Step 8: Add the Lobster
Gently fold in the chopped lobster meat. Be careful not to break up the lobster too much – you want those nice chunks to stand out in the dish.
Step 9: Bake the Mac and Cheese
Preheat your oven to 375°F (190°C). Transfer the lobster mac and cheese mixture into a buttered baking dish. Optional: Top with extra grated cheese or breadcrumbs for a crispy finish. Bake for about 15-20 minutes until the top is golden and bubbly.
Recipe Notes
Lobster Tails
Boiling or steaming are quick and effective methods for cooking lobster tails. Fresh or frozen tails work well, but make sure to thaw if using frozen.
Cheddar Cheese
Sharp cheddar is preferable for its bold flavor. Freshly shredding your cheese is always worth the extra effort as it melts more smoothly than pre-shredded.
Whole Milk
You can use half-and-half for an even creamier sauce.
Parmesan Cheese
Grate it freshly to impart a strong essence. Pre-grated usually includes anti-caking agents that can affect the smoothness of your sauce.
Butter and Flour
This duo creates the roux, which is the foundation for any creamy cheese sauce.
Optional Seasonings
Nutmeg and mustard powder are often used in French béchamel sauces. They can add an unexpected twist.

Recipe Variations
- Lobster Alternatives: Not a fan of lobster? Swap it out for shrimp, crab, or even chicken.
- Spice Level: Add a touch of cayenne pepper or red pepper flakes for a spicy kick.
- Herbs: Fresh herbs like parsley, chives, or thyme can be incorporated for a fresh taste.
- Gluten-Free: Substitute the pasta and flour with their gluten-free counterparts.

FAQs
1. Can I make this dish ahead of time?
Absolutely! You can prepare the lobster mac and cheese and store it in the refrigerator for up to 2 days before baking. Just make sure to cover it well.
2. What’s the best way to reheat leftover lobster mac and cheese?
Reheat in the oven at 350°F (175°C) for about 20 minutes, until it’s warmed through. Avoid the microwave if you can, as it can make the sauce grainy.
3. Is it possible to freeze this dish?
Yes, you can freeze it. After assembling, cover tightly with plastic wrap and foil. It can be stored in the freezer for up to a month. Thaw overnight in the refrigerator before baking.
4. My sauce turned out grainy. What went wrong?
Graininess usually happens if the cheese sauce is cooked at too high a temperature or if pre-shredded cheese is used. Stick to freshly shredded cheese and moderate heat to ensure smoothness.
5. Can I use a different type of pasta?
Absolutely. While elbow macaroni is classic, other types like cavatappi, penne, or rotini work just as well. Just make sure it’s curved or has ridges to hold onto the sauce.
6. Do I have to bake the mac and cheese?
Baking is optional. If you prefer a stovetop version, you can skip the baking step. Just combine the pasta and cheese sauce, then fold in the lobster. Heat everything over low, ensuring it’s well mixed.
