H2: Step-by-Step Instructions 5 (always use H2 and H3)
Step 1 — Cook the spaghetti
Bring a large pot of salted water to a boil and cook the 10 oz spaghetti until al dente per package instructions; reserve about 1/2 cup pasta water, then drain.
Step 2 — Sauté the garlic
In a large skillet over medium heat melt 3 tbsp butter, add the 6 minced garlic cloves, and cook until fragrant (about 30–60 seconds) without browning.
Step 3 — Build the sauce
Pour in 1/4 cup dry white wine and simmer 1–2 minutes to reduce, then stir in 2 cups water, 1 1/4 cups heavy cream, 2 1/2 tsp cajun seasoning, 1 tsp red pepper flakes, and 1/8 tsp salt; simmer until slightly thickened.
Step 4 — Finish with cheese, lemon, and crab
Lower the heat, whisk in 1 cup freshly grated parmesan and 1 tbsp lemon juice until smooth, then gently fold in 2 cups crabmeat and 1/4 cup parsley just to warm through.
Step 5 — Toss and serve
Add the drained spaghetti to the skillet and toss to coat, thinning with reserved pasta water as needed for silky consistency; garnish with extra parsley and parmesan before serving.

H2: Tips for Success Tasty Crab Pasta Alfredo – thegirlskitchen
- Use freshly grated parmesan for the smoothest, creamiest sauce and better melting.
- Keep heat moderate when adding cheese to avoid grainy texture.
- Reserve pasta water to loosen the sauce instead of adding extra cream.
- Gently fold crab in at the end to keep delicate meat from breaking apart.
- For extra crab flavor try a spoonful of angry crab trifecta sauce on the side.
H2: Variations
Here are a few easy ways to change it up:
- Swap the crab for shrimp or lobster for a different seafood twist.
- Make it spicy: increase red pepper flakes or add a dash more Cajun seasoning.
- Dairy-free option: replace heavy cream with full-fat coconut milk or blended soaked cashews and use a dairy-free parmesan alternative.
- Add vegetables: toss in peas, blanched asparagus, or sautéed mushrooms for extra texture.
