Bring a large pot of salted water to a boil. Add 8 oz of fettuccine pasta and cook according to package instructions until al dente. Reserve about ½ cup of pasta water, then drain and set aside.
Heat 2 tablespoons olive oil in a large skillet over medium heat. Add diced onion and sauté for 3-4 minutes until translucent. Stir in minced garlic and diced bell pepper; cook 3 more minutes until fragrant and slightly softened.
Pour in 1 cup chicken broth and bring to a simmer. Stir in 1 cup heavy cream and 2 teaspoons Cajun seasoning. Let sauce bubble gently for about 5 minutes until slightly thickened and flavors meld. Season with salt and pepper to taste.
Gently fold in 1 lb lump crab meat, being careful not to break up the chunks. Warm the crab through in the sauce for 2-3 minutes.
Add cooked fettuccine to the skillet and toss gently to coat evenly in the creamy Cajun crab sauce. Add reserved pasta water a splash at a time if sauce is too thick.
Sprinkle chopped parsley over the top for freshness and serve immediately with crusty bread or a green salad.

Notes
Be gentle when folding in the crab to keep the lumps intact.

Use low-sodium chicken broth to control saltiness.
Reserve pasta water to adjust sauce consistency perfectly.
Substitute heavy cream with coconut cream for a dairy-free version.
