One Pan Shrimp Fettuccine Alfredo

The first time I made shrimp Alfredo, I somehow managed to dirty every single pan in my tiny apartment kitchen. When I discovered you could cook everything in one skillet—the pasta absorbing all that creamy, garlicky goodness while it cooks—I felt like I'd unlocked a secret level of adulting.

I made this for my sister on a rainy Tuesday when she was feeling particularly drained after work. She literally stopped mid bite, looked at me with wide eyes, and asked if I'd been secretly taking cooking classes. That's the kind of reaction that turns a simple dinner into a memory.

Ingredients

• 1 lb large shrimp, peeled and deveined: Fresh shrimp makes all the difference here, and leaving the tails on looks beautiful but feel free to remove them for easier eating
• 12 oz dry fettuccine: The noodles will plump up as they cook in the liquid, so regular fettuccine works better than thinner angel hair which can get mushy
• 2 tbsp unsalted butter: This creates the aromatic base for your sauce, helping the garlic and shallot bloom without burning
• 1 cup heavy cream: This is what gives the sauce that luxurious restaurant style texture and richness
• 1 cup freshly grated Parmesan cheese: Pre grated cheese has anti caking agents that prevent proper melting, so buy a wedge and grate it yourself
• 1/2 cup whole milk: This slightly lightens the sauce without sacrificing creaminess
• 4 garlic cloves, minced: Fresh minced garlic creates a more nuanced flavor than garlic powder, which can taste harsh in creamy sauces
• 1 small shallot, finely chopped: Shallots offer a sweet, mild onion flavor that complements the shrimp without overwhelming it
• 2 1/2 cups low sodium chicken broth: Low sodium is crucial because the sauce reduces and concentrates, and you want control over the final salt level
• 1/2 tsp salt, or to taste: Start with less and adjust at the end since flavors concentrate as the sauce thickens
• 1/4 tsp black pepper: Freshly ground pepper has more complexity than pre ground
• 1/4 tsp crushed red pepper flakes: This adds just enough warmth to cut through the richness without making it spicy
• 2 tbsp chopped fresh parsley: Fresh parsley adds a bright pop of color and a fresh herbal note that balances all that cream

Instructions

Build your aromatic base:

Melt butter in your large deep skillet over medium heat and add the shallot and garlic, stirring constantly for about a minute or two until the kitchen fills with that incredible garlicky fragrance but before anything starts to brown

Sear the shrimp:

Season your shrimp with just a pinch of salt and pepper, then add them to the pan and cook for about two minutes per side until they turn perfectly pink and remove them immediately—overcooked shrimp becomes rubbery and sad

Create the creamy cooking liquid:

Pour in the chicken broth, heavy cream, and milk, then bring everything to a gentle simmer while stirring to incorporate all those flavorful bits left from the shrimp

Cook the pasta directly in the sauce:

Add the dry fettuccine and stir well to submerge every strand, then cook uncovered for ten to twelve minutes, stirring frequently so nothing sticks, until the pasta is al dente and the liquid has transformed into a glossy sauce that coats the back of your spoon

Finish the sauce:

Lower the heat and stir in the Parmesan cheese and red pepper flakes until the cheese melts completely and the sauce becomes impossibly creamy and smooth

Bring it all together:

Return the cooked shrimp along with any juices on the plate back into the pan and toss everything gently for just a minute or two until the shrimp are warmed through and coated in that gorgeous sauce

Season to perfection:

Taste your creation and add more salt and pepper if needed, remembering that Parmesan is naturally salty so you might not need much additional salt

Garnish and serve:

Scatter that fresh parsley over the top for a beautiful finish and serve immediately while the sauce is still velvety and hot

Pin It

This recipe became my go to for celebrating small wins—a promotion at work, a finished project, or just making it through a particularly long week. There's something about the combination of tender shrimp and silky sauce that makes any Tuesday night feel like a special occasion.

Making It Lighter

On days when I want all the flavor without quite as much richness, I swap the heavy cream for half and half. The sauce is slightly less decadent but still wonderfully creamy and satisfying.

Building a Complete Meal

I love serving this with a crisp green salad dressed simply with vinaigrette—the acidity cuts beautifully through the rich sauce. Some crusty garlic bread for soaking up every last drop of sauce never hurts either.

Customizing Your Bowl

Sometimes I add sautéed baby spinach during the last few minutes of cooking, letting it wilt right into the sauce. Sliced mushrooms are another favorite addition—they add earthy flavor and extra substance.

• Keep the shrimp moving in the pan so they cook evenly instead of stewing in their own juices
• Grate your Parmesan right before adding it to prevent clumping
• Have all your ingredients prepped before you start—once the cooking begins, everything moves quickly

Pin It

There's something deeply satisfying about a dish that tastes like it came from a restaurant but leaves you with only one pan to wash. That's the kind of magic worth making again and again.

Recipe FAQs

→ Can I use pre-cooked shrimp?

Yes, add pre-cooked shrimp during the final 2 minutes of heating to warm through without overcooking.

→ What pasta substitutes work well?

Linguine, tagliatelle, or penne make excellent alternatives. Adjust cooking time slightly based on pasta thickness.

→ How do I store leftovers?

Refrigerate in an airtight container for up to 3 days. Reheat gently with a splash of cream to restore sauce consistency.

→ Can I make this lighter?

Substitute half-and-half for heavy cream and increase Parmesan slightly to maintain the rich, creamy texture.

→ Why cook pasta directly in sauce?

Cooking pasta in the sauce releases starch into the liquid, creating a naturally thickened, velvety sauce that clings beautifully.
