One Pan Shrimp Fettuccine Alfredo

The first time I made this Alfredo, I was skeptical about cooking pasta directly in the sauce. I stood there watching the liquid bubble down, convinced I'd ruined dinner, but suddenly there it was—perfectly coated noodles and the silkiest sauce I'd ever created. Now it's my go-to when I want something impressive without the mountain of dishes.

I made this for my sister last winter when she was visiting, and she actually stopped mid-bite to ask what restaurant I'd ordered from. The way the shrimp stays tender while the pasta gets that perfectly coated gloss still feels like magic every single time.

Ingredients

• Large shrimp: Peeled and deveined saves precious time, and buying them frozen means they're ready whenever inspiration strikes
• Dry fettuccine: The flat surface grabs sauce beautifully, and cooking it directly creates that starch-thickened magic
• Unsalted butter: Lets you control the salt level since both cheese and broth bring their own seasoning
• Heavy cream: Essential for that velvety restaurant texture that milk alone just can't achieve
• Freshly grated Parmesan: Pre-grated has anti-caking agents that make sauce grainy, so grab a wedge and grate it yourself
• Whole milk: Lightens the cream just enough so the sauce coats instead of clumping
• Garlic cloves: Mince them right before cooking so their oils are fresh and potent
• Shallot: Adds subtle sweetness that balances the rich dairy without the sharp bite of onion
• Low-sodium chicken broth: Provides depth while keeping the salt level under your control
• Salt and pepper: Adjust at the end since ingredients reduce and concentrate as they cook
• Crushed red pepper flakes: Just enough warmth to cut through the cream, but totally optional if you prefer mild
• Fresh parsley: Brings a bright pop of color and fresh flavor that cuts the richness

Instructions

Build the flavor base:

Melt butter in your largest deep skillet over medium heat, then add shallot and garlic. Cook just until they release that incredible fragrance and turn translucent, about 1-2 minutes—do not let them brown or they'll turn bitter.

Sear the shrimp:

Season your shrimp with a pinch of salt and pepper, then add them to the fragrant oil. Cook for exactly 2 minutes per side until they turn pink and opaque, then remove them immediately so they don't overcook and turn rubbery.

Create the sauce base:

Pour in the chicken broth, heavy cream, and milk into that same flavorful pan. Bring everything to a gentle bubble, watching as the dairy swirls together into a luxurious bath.

Cook the pasta:

Add the dry fettuccine right into the liquid, using tongs to push and turn the noodles until they're submerged. Cook uncovered for 10-12 minutes, stirring frequently, until the pasta is al dente and most of the liquid has transformed into a glossy sauce that coats each strand.

Make it creamy:

Lower the heat and stir in the Parmesan and red pepper flakes. Watch as the cheese melts and the sauce thickens into something that looks like it came from a professional kitchen.

Bring it together:

Return those beautiful pink shrimp and any juices on the plate back to the pan. Toss everything gently for just 1-2 minutes until the shrimp are heated through and coated in sauce.

Season to perfection:

Taste and adjust with more salt and pepper if needed. The flavors concentrate during cooking, so start conservative and add gradually.

Finish with flair:

Scatter fresh parsley over the top and serve immediately while the sauce is at its silkiest.

Save to Pinterest

This recipe became my daughter's most requested birthday dinner after she watched me make it at 16 and announced she needed to learn it before leaving for college. Now she calls me from her apartment every time she makes it, usually to report that she's added her own twist but kept the one-pan genius intact.

Making It Lighter

Swap half-and-half for the heavy cream when you want something a little less indulgent but still satisfying. The sauce will be slightly thinner but still deliciously creamy.

Easy Veggie Additions

Sauté sliced mushrooms or baby spinach right after cooking the shrimp. The vegetables absorb all that garlic butter flavor and add color without extra effort.

Serving Perfection

A crisp green salad with acidic vinaigrette cuts through the richness, while warm garlic bread is practically mandatory for sopping up every drop. A chilled white wine like Pinot Grigio makes everything feel like a restaurant occasion.

• Grate extra Parmesan at the table because everyone always wants more
• Keep some pasta water handy just in case the sauce tightens up too much
• Have your ingredients prepped before you start—this recipe moves fast once you begin cooking

There's something deeply satisfying about a dish that looks and tastes luxurious but comes together with such minimal fuss. Hope this becomes your weeknight comfort too.

Recipe FAQs

→ Can I use different pasta shapes?

While fettuccine works beautifully for coating with the creamy sauce, you can substitute linguine, spaghetti, or penne. Cooking times may vary slightly—check for doneness a minute or two earlier with thinner pasta.

→ How do I prevent the sauce from becoming too thick?

The sauce naturally thickens as pasta releases starch. If it becomes too thick, simply add small amounts of warm chicken broth or milk until you reach the desired consistency. Add gradually, stirring constantly.

→ Can I make this with frozen shrimp?

Yes, thaw frozen shrimp completely and pat dry before cooking. Excess moisture will prevent proper searing. Thaw overnight in the refrigerator or run under cold water for 15 minutes, then drain thoroughly.

→ What can I substitute for heavy cream?

Half-and-half creates a lighter sauce with similar creaminess. For a dairy-free option, use full-fat coconut milk, though it will add subtle coconut flavor. The sauce may be slightly less thick.

→ How long does this keep in the refrigerator?

Store in an airtight container for up to 3 days. The sauce will thicken considerably when chilled—reheat with a splash of milk or broth over low heat, stirring gently to restore creaminess without separating.

→ Can I add vegetables to this dish?

Absolutely. Sautéed mushrooms, baby spinach, or peas work wonderfully. Add mushrooms when cooking the shallots, or stir in leafy greens like spinach during the last 2 minutes of pasta cooking time.
