Crab Alfredo has always reminded me of the kind of meal you make when you want to slow down for a moment, sit at the table a little longer, and savor something rich and comforting. This version gives you that restaurant-style decadence but with the warmth of a home-cooked dish. The combination of tender pasta, real butter, creamy sauce, and sweet crab meat feels like the sort of treat I save for days when I want dinner to feel special without being fussy.

I’ve made this for quiet evenings at home and for family dinners when I want something generous and indulgent. It’s one of those dishes where the smell alone — buttery garlic meeting warm cream — tells you the meal is going to be good.
Ingredients You’ll Need
(Shuffled with quantities first)
-
1 pound pasta (linguine or fettuccine work beautifully)
-
2 cups lump crab meat or fresh crab from legs
-
1 cup half-and-half
-
½ cup freshly grated parmesan
-
4 tablespoons butter
-
½ teaspoon garlic powder
-
Salt and pepper to taste
-
Optional: fresh parsley for serving
Freshly grated parmesan melts into the sauce much more smoothly than the pre-shredded kind — it gives the Alfredo its silky texture.
How I Make This Crab Alfredo at Home
Cooking the Pasta
I start with a large pot of salted boiling water. While the pasta cooks, the sauce comes together quickly, so timing feels natural and relaxed.
Building the Alfredo Sauce
In a separate pan, I melt the butter gently. Once it’s bubbling softly, I sprinkle in the garlic powder. Then I pour in the half-and-half and let it warm slowly. This is where the sauce begins to thicken. When I stir in the parmesan, the mixture transforms into something smooth and velvety — the exact texture that makes Alfredo so comforting.
Adding the Crab
Once the sauce is ready, I fold in the crab meat. If I’m using fresh crab from legs, I take a moment to pick through and pull out large, tender pieces. The heat from the sauce warms the crab perfectly without overcooking it.
Bringing Everything Together
When the pasta is hot and ready, I transfer it straight into the sauce. A gentle toss helps the noodles soak up the creamy mixture so every bite feels luxurious.
A sprinkle of parsley gives the dish a bit of color, but it’s not necessary — the star here is the crab.

What I Like to Serve With This Dish
A Simple Green Salad
Something crisp with lemon dressing balances the richness nicely.
Warm Bread
Any crusty loaf works, but rosemary bread is my favorite pairing. It’s wonderful for catching the sauce left on the plate.
Steamed Veggies
Asparagus or broccoli add a fresh note that complements the buttery pasta.
Ingredient Swaps That Work Well
Heavy Cream
If you want a richer Alfredo, heavy cream makes it even silkier.
Frozen Crab Meat
Frozen or packaged lump crab meat works well when fresh isn’t available.
Add-In Ideas
Sautéed mushrooms, a handful of spinach, or even a little lemon zest can add personality depending on what you’re craving.
How I Store Leftovers
I transfer leftovers to airtight containers and refrigerate them for up to two days. Cream sauces tend to thicken in the fridge, so when reheating, I add a splash of milk or cream to bring the texture back to what it was.
Reheating gently over low heat keeps the sauce from separating.
Slip-Ups I’ve Learned to Avoid
Overheating the Cream
If the sauce boils too hard, it can separate. Keeping the heat gentle gives the best texture.
Using Pre-Shredded Cheese
It doesn’t melt smoothly, and the sauce ends up grainy.
Adding the Crab Too Early
Letting the crab simmer can toughen it. Fold it in once the sauce is nearly done.

FAQs
Can I use imitation crab?
You can. It won’t have the same sweetness as real crab, but it still works for a budget-friendly version.
Can I use other seafood?
Shrimp, scallops, or a mix of seafood blend nicely with Alfredo sauce.
Can this be made lighter?
Half-and-half is already lighter than traditional heavy cream versions. You can thin it slightly with milk if needed.
Does this freeze well?
Cream sauces tend to separate when frozen, so I prefer making it fresh.
What pasta shape works best?
Long noodles like linguine or fettuccine hold the sauce beautifully.
Copycat Red Lobster Crab Alfredo
This rich and comforting crab Alfredo tastes just like the version you’d find at a classic seafood restaurant—creamy, buttery, and full of tender pieces of crab.
Ingredients
- 1 pint half and half
- 4–6 crab legs
- ½ cup unsalted butter
- 2 tablespoons cream cheese
- ½–¾ cup Parmesan cheese
- 1 teaspoon garlic powder
- pasta of your choice (linguine works well)
- salt and pepper to taste
Instructions
- Warm a saucepan over medium heat and melt the butter until smooth and fragrant. Add the cream cheese and let it soften into the butter, stirring gently so it blends into a creamy base. Pour in the half and half and sprinkle in the Parmesan, letting the cheese melt slowly into the sauce. Add the garlic powder and stir until everything is silky. Lower the heat and let the sauce simmer until it thickens and becomes velvety.
- While the sauce cooks, bring a large pot of water to a boil. Add the crab legs and cook until the shells turn bright and the meat is heated through. In a separate pot, cook your pasta according to the package directions until al dente.
- Remove the crab legs, crack them open, and pull out the meat. Pat the pieces dry with a paper towel so the sauce doesn’t thin out. Drain the pasta and spoon it into bowls, then pour the warm Alfredo sauce over top. Add the crab meat right over the sauce, letting the heat soften it just slightly before serving.
- This dish works beautifully with extra Parmesan or a sprinkle of black pepper on top.
