Creamy Chicken Shrimp Alfredo Pasta

Easy Homemade Chicken Shrimp Alfredo

The smell of garlic hitting hot butter and the loud sizzle of shrimp hitting the pan tell you exactly when this is going to be good. It's all about those high-heat sounds and the way the cream bubbles into a thick, glossy coating for the pasta.

This chicken shrimp alfredo puts a lot of focus on the proteins. Instead of boiling everything in the sauce, you sear the chicken and shrimp first. This gives you those brown, caramelized edges that add a deep, savory contrast to the cream.

You can expect a dish that's heavy on the garlic and Parmesan, with a hit of nutmeg that you can't quite place but makes the whole thing taste professional. It's a crowd-pleaser that feels special without needing a whole day in the kitchen.

What Makes This Work

• Separate Searing: Cooking chicken and shrimp in stages prevents the shrimp from turning into rubber while the chicken finishes.
• Starchy Water: Saving a bit of pasta water helps the sauce cling to the noodles instead of sliding off to the bottom of the bowl.
• Low Heat Finishing: Adding cheese on low heat helps prevent the fats from separating, which keeps the sauce smoother.

The Right Ingredients

• 1 lb skinless, boneless chicken breast, cut into 1-inch cubes
• 1 lb large shrimp, peeled and deveined
• 2 tbsp olive oil
• 1 tsp salt
• 1/2 tsp black pepper
• 1 tsp garlic powder
• 1 lb fettuccine pasta
• 4 qts water
• 2 tbsp salt
• 1/2 cup unsalted butter
• 3 cloves garlic, minced
• 2 cups heavy cream
• 1 1/2 cups freshly grated Parmesan cheese
• 1/4 tsp ground nutmeg

For the Proteins

• Chicken breast (1 lb, 1-inch cubes): A lean protein that carries the garlic powder perfectly.
• Large shrimp (1 lb, peeled and deveined): Opt for wild-caught for a firmer bite.
• Olive oil (2 tbsp): Ideal for searing due to its smoke point.
• Salt (1 tsp), Black pepper (1/2 tsp), Garlic powder (1 tsp): Essential seasonings for a flavorful foundation.

For the Pasta

• Fettuccine pasta (1 lb): Its wide ribbons are perfect for holding onto thick cream sauces.
• Water (4 qts) and Salt (2 tbsp): Salting the water is key to seasoning the pasta from within.

For the Creamy Garlic Sauce

• Unsalted butter (1/2 cup): Creates a rich base and allows the garlic to bloom.
• Garlic (3 cloves, minced): Use fresh garlic to achieve a pungent, aromatic quality.
• Heavy cream (2 cups): Adds the necessary fat and volume for a luscious consistency.
• Freshly grated Parmesan cheese (1 1/2 cups): Acts as the main source of salt and savoriness.
• Ground nutmeg (1/4 tsp): A pinch provides a subtle, nutty warmth.

Cooking Gear Needed

A 12-inch skillet is ideal for this recipe, as it provides enough space for the chicken and shrimp to sear instead of steaming in their own juices. You will also need a large stockpot for the pasta and a whisk for the sauce.

Step by step Guide

For Perfectly Seared Proteins

Warm 2 tbsp olive oil in a 12-inch skillet over medium-high heat. Season the cubed chicken and shrimp with 1 tsp salt, 1/2 tsp black pepper, and 1 tsp garlic powder.

Sear the chicken in the pan until golden brown and it hits an internal temp of 165°F (74°C). Transfer the chicken to a plate and set aside.

In the same skillet, cook the shrimp for 1-2 minutes per side until they turn pink and reach 145°F (63°C) internally. Remove them immediately to keep them tender.

For Al Dente Texture

While preparing the proteins, bring 4 qts of water and 2 tbsp salt to a rolling boil in a large pot. Add 1 lb fettuccine and cook per the package instructions, but pull it out 1 minute before it reaches 'al dente'.

Keep 1/2 cup of the starchy pasta water before draining the noodles.

For a Smooth Sauce

Lower the skillet heat to medium. Melt 1/2 cup unsalted butter and sauté 3 cloves of minced garlic until fragrant (about 1 minute).

Stir in 2 cups heavy cream, allowing it to simmer lightly for 3-5 minutes until the sauce slightly thickens.

Reduce heat to low. Gradually whisk in 1 1/2 cups grated Parmesan cheese and 1/4 tsp nutmeg, stirring constantly until the sauce is smooth and glossy.

For the Final Assembly

Toss the drained pasta into the skillet with the sauce. Fold in the seared chicken and shrimp, coating everything well.

If the sauce is too thick, stir in a bit of the reserved pasta water to achieve a silky consistency before serving.

Quick Fixes

Fixing a Grainy Sauce

If the sauce looks curdled or grainy, the heat was likely too high, which causes the cheese to separate. Take the pan off the heat and whisk in a tablespoon of warm pasta water or a splash of cream. This helps re-bind the fats.

Saving Rubbery Shrimp

Rubbery shrimp happen when they stay in the pan too long. Since you can't "un-cook" them, the best fix is to add a tiny pinch of baking soda to the shrimp before searing next time. This keeps them tender.

Fixing a Sauce That's Too Thick

Cream sauces thicken fast as they cool. If it's turning into a paste, stir in the reserved pasta water one tablespoon at a time. The starch in the water loosens the sauce without breaking the emulsion.

Mix-ins and Swaps

To incorporate some greens, fold in two handfuls of fresh baby spinach just before serving. The remaining heat will soften the leaves in about 30 seconds without overcooking them.

For a different noodle, you can try a Linguine Alfredo recipe style approach with thinner pasta to make the meal feel slightly lighter. If you prefer a shorter pasta, chicken alfredo penne is an excellent way to capture more sauce in every mouthful.

Storing and Reheating

Keep extra servings in a closed container in the refrigerator for up to 3 days. It is normal for the sauce to thicken to a heavy cream-like consistency as it cools.

Whenever possible, avoid the microwave, as it can make the shrimp rubbery and cause the sauce to split into oil and solids. Instead, warm the pasta in a skillet over low heat until the chicken and shrimp reach 165°F (74°C) inside. Stir in 2-3 tablespoons of water or milk to loosen the sauce and heat gently.

This recipe is not suitable for freezing. The cream and cheese typically separate during the freezing and thawing process, which results in a grainy texture.

Serving Suggestions

Serve this in warmed bowls to keep the sauce from thickening too quickly. A sprinkle of fresh parsley or extra cracked black pepper on top adds a nice pop of color. I like a squeeze of fresh lemon juice over the shrimp right before eating to cut through the richness of the butter and cream.
