Ingredients for baked creamy chicken alfredo

Creamy sauce, juicy chicken, and cheesy pasta—all baked together in one pan.

The Parmesan is non-negotiable here—freshly grated from a wedge makes all the difference. Whole Foods or Trader Joe's have the best selection of pre-grated, but I always grab a wedge myself. The chicken matters too—boneless, skinless breasts cook evenly, but thighs work if you prefer more flavor. For the pasta, fettuccine is classic, but penne or rigatoni hold up well too. Look for whole wheat options if you want extra fiber without sacrificing texture.

No heavy cream? Full-fat coconut milk works in a pinch, though the flavor will differ slightly. Short on Parmesan? Pecorino Romano at half the amount gives a sharper bite. The flour is just for thickening—all-purpose works fine, but if you're gluten-free, swap for cornstarch. The chicken broth adds depth, but vegetable broth works too. For extra richness, add a splash of half-and-half at the end. Red pepper flakes are optional, but trust me—they make it pop.

This reheats beautifully—honestly tastes better the next day once everything melds. Keeps for 4-5 days in the fridge, freezes for 3 months. I always double the recipe because leftovers are perfect for lunches. Store the sauce separately if you want to reheat just that—it gets thicker when cold. Garnish with fresh parsley right before serving (the good stuff, not the dried kind).

Step-by-step instructions for creamy chicken alfredo pasta

Here's how to make this rich, cheesy one-pan wonder without the mess.

Preheat your oven to 375°F. Heat 0.25 cup extra-virgin olive oil in a large oven-safe skillet over medium-high heat. Add the 1.5 lb boneless, skinless chicken breast cut into 1-inch pieces and cook for 4-5 minutes until the edges are golden brown and the chicken is cooked through.

Here's the thing—don't overcrowd the pan. Cook the chicken in batches if needed so it gets properly seared. You want that crispy exterior to lock in all those juices when we bake it later. Once golden, remove the chicken and set it aside on a plate.

In the same skillet (no need to wipe it clean—those browned bits are flavor gold), reduce heat to medium and add 0.5 cup unsalted butter and 4 cloves minced garlic. Cook for 1-2 minutes until the garlic is fragrant but not browned—you don't want it to turn bitter.

Sprinkle in the 0.25 cup all-purpose flour all at once and whisk vigorously for 1 minute until it forms a smooth paste. This is your roux, and it's what will thicken that creamy sauce. Slowly pour in the 0.5 cup chicken broth while whisking constantly to prevent lumps.

Let the mixture simmer for 2 minutes until it starts to thicken. Then, gradually whisk in the 1 cup heavy cream and 1 cup freshly grated parmesan cheese. Keep whisking until the sauce is smooth and velvety—this should take about 3-4 minutes of gentle simmering. Season with 1 tsp salt and 0.5 tsp black pepper.

Return the seared chicken to the skillet and stir to coat it in the creamy sauce. Add the 12 oz fettuccine pasta (broken in half) and toss everything together until the pasta is evenly coated. If the mixture seems too thick, add 2-3 tablespoons of water to loosen it.

Transfer the skillet to the preheated oven and bake uncovered for 15-18 minutes, stirring halfway through, until the pasta is tender and the sauce has thickened to a perfect consistency. You'll know it's ready when the edges are bubbling and the cheese is fully melted and golden.

Once baked, remove the skillet from the oven and let it sit for 2 minutes to thicken slightly. Stir in the 0.25 cup chopped fresh parsley and 0.25 tsp red pepper flakes (if using) for a pop of color and a little heat. Taste and adjust seasoning if needed—sometimes you need a tiny bit more salt to balance the richness.

Serve immediately, straight from the pan, with extra grated parmesan on top. This dish is all about that creamy, cheesy goodness clinging to every strand of pasta. Don't skip the parsley—it adds freshness that cuts through the richness perfectly.

Essential equipment for this dish

Oven-Safe Skillet

You'll need a large oven-safe skillet with a 5-quart capacity—I swear by my All-Clad Stainless Steel skillet for this recipe. The deep sides prevent spills, and the stainless steel conducts heat evenly.

If you don’t have one, a cast iron skillet (like my Lodge 10.25-inch) works perfectly too—just preheat it longer to avoid temperature shock. Avoid non-stick pans for this dish; the high heat can damage coatings and release harmful fumes when baking.

Whisk for Smooth Sauce

A balloon whisk is your best friend for this recipe—it incorporates air into the sauce, creating that signature light, velvety texture. I use a OXO Good Grips whisk because it’s durable and has angled wires that cut through ingredients effortlessly.

For extra richness, whisk vigorously when combining the heavy cream and parmesan. A hand mixer works in a pinch, but you risk overmixing and breaking the sauce’s delicate emulsion. 🥛

Measuring Tools

Precision matters here, especially with the roux and sauce thickness. Invest in a stainless steel measuring spoons set (like Farberware) for accurate measurements of flour, salt, and pepper. For liquids, a liquid measuring cup with clear markings ensures you don’t overdo the heavy cream or chicken broth.

Pro tip: Use a kitchen scale for the parmesan—1 cup grated equals about 1 ounce, but pre-shredded cheese often has anti-caking agents that add bulk. Freshly grated is always better.

Cheese Grater

Freshly grated parmesan makes all the difference in this dish. A box grater (like the Microplane) is my go-to because it produces fine, even shreds that melt smoothly into the sauce. Avoid pre-shredded cheese—it’s usually coated with anti-caking agents that prevent proper melting.

If you’re short on time, a food processor with a grating attachment works, but it can create uneven shreds. For extra flavor, mix ½ cup parmesan with ½ cup pecorino romano—the sharper taste cuts through the creaminess beautifully. 🧀

Tongs for Tossing

Long-handled tongs (like OXO Good Grips) are essential for evenly coating the pasta and chicken in the sauce. They let you toss everything without overmixing, which keeps the sauce silky. Avoid wooden spoons—they can scratch non-stick pans and absorb flavors over time.

For stirring the sauce, a heat-resistant silicone spatula (like Epicurean) is perfect—it won’t melt or warp under high heat. Keep one handy for scraping up any stuck-on bits from the skillet’s edges. 🍝

Optional: Oven Thermometer

Oven temperatures can vary wildly, and this recipe relies on precise baking. An oven thermometer (like Thermoworks) ensures your oven is actually at 375°F—not the "guess-timate" setting. I’ve seen home ovens run 25°F hotter or colder than the dial indicates.

If your oven runs hot, reduce the temperature to 350°F to prevent the sauce from separating. For even cooking, place the skillet on the middle rack where heat circulates most evenly. ⚡
