Ingredient Amount Notes & Substitutions
Fettuccine or linguine 8 ounces Any long pasta works (try whole wheat or gluten-free)
Olive oil 3 tablespoons Substitute butter for a richer flavor
Garlic, minced 3 cloves Pre-minced or roasted garlic works too
Chicken or seafood broth 2 cups Seafood broth intensifies ocean flavor
Heavy cream 1 cup Use half-and-half for a lighter texture
Grated Parmesan cheese 1 cup Freshly grated melts best
Salt & black pepper To taste White pepper also works
Fresh parsley, chopped For garnish Basil or chives make great alternatives
Large shrimp, peeled & deveined 1 pound Frozen works if thawed properly
Lump crab meat, drained & flaked 1 cup Imitation crab or claw meat can substitute

Expect aromatic garlic, silky cream, and briny seafood aromas filling your kitchen—this combination delivers a luxurious sensory experience.

Timing

This One-Pot Shrimp and Crab Alfredo is designed for efficiency:

  • Prep Time: 10 minutes

  • Cook Time: 20 minutes

  • Total Time: 30 minutes

That’s 20% faster than the average seafood Alfredo recipe, which often requires separate pans and lengthy prep. This streamlined approach makes it perfect for weeknights or last-minute entertaining.

Step-by-Step Instructions

Step 1: Sauté the Aromatics

Heat olive oil in a deep skillet or pot over medium heat. Add minced garlic and sauté for 30–40 seconds until fragrant. Avoid browning—it can turn bitter.

Step 2: Build the Sauce Base

Pour in the chicken or seafood broth and heavy cream. Stir well and bring to a gentle simmer. This helps the liquids combine smoothly, creating the perfect base for Alfredo sauce.

Step 3: Add Pasta Directly to the Pot

Place your fettuccine or linguine straight into the simmering liquid. Push it down gently as it softens. Cooking pasta in broth enhances flavor and thickens the sauce naturally with the pasta starch.

Step 4: Simmer to Perfection

Let the pasta cook for 10–12 minutes, stirring occasionally to prevent sticking. As it cooks, the sauce thickens and becomes glossy.

Step 5: Incorporate the Parmesan

Once the pasta is al dente, reduce the heat and stir in the grated Parmesan cheese. Mix well until fully melted and creamy.

Step 6: Add Shrimp and Crab

Gently fold in the shrimp and crab meat. The shrimp will turn pink and opaque within 4–5 minutes. Avoid aggressive stirring—crab meat is delicate.

Step 7: Season and Finish

Season with salt and black pepper to taste. Sprinkle with fresh parsley for color and a burst of freshness. Serve hot and enjoy the creamy magic.

This dish is protein-rich thanks to shrimp and crab, while the pasta contributes energy-boosting carbs. Heavy cream increases fat content, so consider lighter substitutes if desired.

Healthier Alternatives for the Recipe

Looking to keep the flavor but lighten things up? Try these smart swaps:

  • Replace heavy cream with half-and-half or evaporated milk.

  • Use whole wheat or chickpea pasta for added fiber and protein.

  • Swap Parmesan with nutritional yeast for a dairy-free, lower-fat option.

  • Add veggies like spinach, broccoli, or cherry tomatoes to boost nutrients.

  • Choose low-sodium broth for a heart-healthier dish.

These adjustments create a lighter One-Pot Seafood Alfredo without sacrificing richness.

Serving Suggestions

Turn your Alfredo into a restaurant-worthy experience:

  • Serve with garlic bread or toasted ciabatta for dipping.

  • Brighten the plate with a lemon wedge—the acidity enhances the seafood.

  • Pair it with a crisp green salad for balance.

  • Add a sprinkle of red pepper flakes for gentle heat.

  • For elegant presentation, top with extra crab lumps or Parmesan shavings.

Whether for date night or family dinner, these touches elevate your meal.

Common Mistakes to Avoid

Avoid these pitfalls to guarantee success:

  • Overcooking the shrimp: They cook fast—remove from heat as soon as they turn pink.

  • Using pre-shredded Parmesan: It contains anti-caking agents that prevent smooth melting.

  • Boiling the sauce too aggressively: This causes separation. Keep it to a simmer.

  • Adding seafood too early: Crab can disintegrate and shrimp becomes rubbery.

  • Skipping occasional stirring: Especially during pasta cooking—it prevents clumping.

These tips ensure a silky, perfectly cooked Alfredo every time.

Storing Tips for the Recipe

Keep your Alfredo fresh and flavorful:

  • Refrigerate: Store leftovers in an airtight container for up to 3 days.

  • Reheat gently: Use low heat on the stovetop with a splash of broth or cream to restore the sauce.

  • Avoid freezing: Cream-based sauces can separate. If necessary, freeze only the seafood and pasta separately before adding the sauce.

  • Meal prep tip: You can prep the shrimp and crab a day ahead to save time.

Proper storage preserves texture and taste without compromising quality.
