Ingredients for baked chicken pasta recipe white sauce
Pantry staples meet restaurant-quality comfort in one pan—creamy, cheesy, and ready in 30 minutes.
| Ingredient | Amount | Notes |
|---|---|---|
| Chicken Breast 🍗 | 1 ½ lb | Boneless, skinless, cut into bite-sized pieces |
| Fettuccine Pasta 🍝 | 12 oz | Uncooked, any shape works too |
| Heavy Cream 🥛 | 1 cup | Full-fat for best creaminess |
| Milk 🥛 | ½ cup | Whole milk preferred |
| Butter 🧈 | ½ cup | Unsalted, cut into small cubes |
| All-Purpose Flour 🌾 | ¼ cup | For thickening sauce |
| Garlic Cloves 🧄 | 4 cloves | Minced for sauce flavor |
| Shallot 🧅 | 1 whole | Finely chopped, or sub onion |
| Parmesan Cheese 🧀 | ½ cup | Freshly grated from block |
| Dried Thyme 🌿 | 1 tsp | Or 1 tbsp fresh thyme |
| Ground Black Pepper 🌶️ | ½ tsp | Freshly ground preferred |
| Salt 🧂 | 1 tsp | Kosher or sea salt |
| Olive Oil 🫒 | 2 tbsp | For greasing the pan |
| Fresh Basil Leaves 🌿 | ¼ cup | Chopped, for garnish |
The chicken is the star, so pick boneless, skinless breasts—they cook evenly and stay juicy. Most grocery stores carry them pre-cut, but if you're buying whole, trim off any fat or silver skin first. Costco or Trader Joe's have great prices on bulk chicken, and I always grab extra for lunches. For the pasta, uncooked works best here—it absorbs the sauce perfectly while baking. If you're in a pinch, use pre-cooked but drain it well to avoid a soggy mess. The sauce relies on full-fat dairy, so don't skimp on the heavy cream and butter—it's what makes this dish feel luxurious.
No heavy cream? Half-and-half or whole milk plus 2 tbsp cream cheese gets you close, though the texture won't be quite as rich. Fresh thyme is ideal, but dried works at one-third the amount. The shallot adds depth—skip it if you've got leftover onion (finely chopped). For the Parmesan, grate it yourself from a wedge—pre-grated tastes like sawdust in comparison. Want more flavor? Add a pinch of nutmeg to the sauce. The olive oil is just for greasing, but use a good-quality extra-virgin—it makes the whole dish taste better. And if you're out of fresh basil, dried oregano works in a pinch.
This dish reheats beautifully—honestly tastes better the next day once everything melds. Store leftovers in an airtight container for 4-5 days in the fridge, or freeze for 3 months. I always double the recipe because it's perfect for meal prep—just portion into containers before baking. The sauce thickens as it cools, so add a splash of milk if it seems too stiff when reheating. Garnish with fresh basil right before serving—it brightens up the whole dish.

Step-by-step instructions for creamy baked chicken pasta
Let's create this dreamy one-pan dish where tender chicken and al dente pasta swim in velvety white sauce.
Sear the Chicken for Maximum Flavor
Preheat your oven to 375°F. Heat 2 tablespoons olive oil in a large oven-safe skillet over medium-high heat. Add the 1.5 lb chicken breast cut into bite-sized pieces, seasoning each piece generously with 1 teaspoon salt and ½ teaspoon ground black pepper. I like to press the seasoning into the chicken so it sticks during cooking.
Sear the chicken for 4-5 minutes until the pieces are golden brown on all sides and cooked through to 165°F internally. Remove the chicken from the skillet and set it aside on a plate. This initial searing creates that delicious crust that'll hold up through baking.
Build the Creamy White Sauce Base
In the same skillet (no need to clean it - those browned bits are flavor gold), add ½ cup butter and let it melt over medium heat. Add the 1 whole shallot and 4 cloves minced garlic, cooking for 2-3 minutes until softened and fragrant. You'll smell that sweet garlic aroma - that's when you know it's ready.
Sprinkle in ¼ cup all-purpose flour and whisk vigorously for 1-2 minutes until the mixture turns golden brown. This is your roux - the foundation of our creamy sauce. Immediately pour in ½ cup milk and whisk constantly to prevent lumps from forming. Let this simmer for 2 minutes until slightly thickened.
Combine and Bake to Perfection
Return the seared chicken to the skillet and stir to coat in the sauce. Add 1 cup heavy cream, 1 teaspoon dried thyme, and ½ cup grated parmesan cheese. Toss everything together until the chicken is fully coated in that luscious white sauce.
Add the 12 oz fettuccine pasta (uncooked) and stir gently to distribute evenly. The pasta will cook in the sauce during baking. Transfer the skillet to the preheated oven and bake uncovered for 25-30 minutes, or until the pasta is tender and the sauce has thickened to your desired consistency.
Finish and Serve with Fresh Herbs
Remove the skillet from the oven and let it rest for 5 minutes off the heat. This resting time allows the sauce to thicken slightly and the flavors to meld together. Stir in the ¼ cup chopped fresh basil leaves just before serving for that bright, fresh finish.
Taste and adjust seasoning if needed - you might want to add a pinch more salt or pepper. The pasta should be al dente with that creamy sauce clinging beautifully to each strand. Serve immediately while warm, and watch everyone dig into this comforting one-pan masterpiece.
Pro Tips For Making Baked Chicken Pasta Recipe White Sauce
- SEAR CHICKEN FIRST: Skip the bland baked chicken—hit it with a quick 3-4 minute sear in a hot pan before baking. The crust locks in flavor, and you won’t end up with rubbery breast meat that disappears into the sauce. (Yes, even if you’re impatient like me.)
- DON’T BOIL PASTA DRY: Cook fettuccine al dente (1 minute less than package says) and drain it right into the baking dish. The residual starch clings to the chicken and sauce, making everything stick together like it’s supposed to. Overcooked pasta turns mushy in the oven—trust me, I’ve learned this the hard way.
- WHISK COLD CREAM: Chill your heavy cream and milk before mixing with butter—it prevents curdling when the sauce hits the oven. I used to toss them in straight from the fridge, and the sauce would split like a bad joke. Now? Smooth every time.
- BAKE COVERED THEN UNCOVERED: Start with foil on for the first 20 minutes to melt the cheese and thicken the sauce, then remove it for the last 10. This keeps the sauce creamy without turning the top into a sad, watery mess. (Your future self will thank you.)
Essential equipment for baked chicken pasta recipe white sauce
Oven-Safe Skillet
An oven-safe skillet is your secret weapon for this recipe—it handles both stovetop searing and oven baking without transfer. I swear by All-Clad Stainless Steel or Le Creuset Dutch ovens for their even heat distribution, but budget-friendly options like Calphalon or Farberware work perfectly too.
Make sure it's at least 10-inch diameter to accommodate the pasta and chicken comfortably. 🔥
If you don't own an oven-safe skillet, a heavy-bottomed stainless steel or cast iron pan (like Lodge) will work—just transfer the dish to a baking sheet before putting it in the oven. Avoid thin, non-stick pans that can warp under high heat.
Whisk for Smooth Sauce
A balloon whisk is my go-to for blending the white sauce—it incorporates air and prevents lumps better than a regular fork. The OXO Good Grips model has a comfortable handle and durable wires.
For extra-smooth results, I recommend whisking vigorously when adding the milk to the roux to break up any potential clumps. 💫
No whisk? A hand mixer or immersion blender works in a pinch, but whisking by hand gives you better control over the sauce's texture. Just be patient—this is where the magic happens!
Measuring Tools
Precision matters when it comes to the sauce ratio. I use a stainless steel measuring cup set (like KitchenAid) for liquids and a digital kitchen scale for ingredients like flour and butter.
For herbs and spices, a small measuring spoon set ensures you hit those exact ½ teaspoon or 1 teaspoon marks. A scale is especially helpful for cheese—½ cup grated Parmesan can vary wildly in weight!
Cutting Tools
Sharp tools make prep faster and safer. A chef's knife (I love the Wüsthof Classic) and a cutting board (like Teakhaus bamboo) are essential for dicing chicken and mincing garlic. For the shallot, a microplane or fine grater works wonders if you want to avoid chopping. 🌶️
Don’t skip sharpening your knife—dull blades slip and make prep frustrating. A Whetstone or electric sharpener keeps your tools in top shape. If you’re new to knives, practice on the shallot first—it’s small but forgiving!
Baking Sheet Backup
Even if your skillet is oven-safe, keep a rimmed baking sheet nearby for emergencies. If your sauce threatens to overflow or the pan isn’t stable, transfer the dish to the sheet and slide it into the oven. A half-sheet pan (13x9-inch) is ideal for this backup plan. 💡
Pro tip: Line the baking sheet with parchment paper for easy cleanup—just lift the paper out after baking instead of scrubbing the pan.

Frequently asked questions
Can I use pre-cooked pasta in this recipe?
Yes, but with a few adjustments. Pre-cooked pasta absorbs more sauce during baking, so reduce the amount of liquid in the white sauce by 2 tablespoons (use 0.8 cup milk instead of 0.5 cup). Also, drain the pasta very well and pat it dry with a paper towel before adding it to the pan. This helps prevent a watery mess.
What's the best way to make this dish ahead of time?
This recipe reheats beautifully! Assemble everything in the skillet up to the baking step, cover tightly with foil, and refrigerate for up to 24 hours. When ready to bake, add 1-2 tablespoons milk to the sauce before baking to compensate for any thickening that occurred during storage. Bake as directed, adding 5-10 extra minutes if needed.
Can I substitute chicken thighs for breasts?
but adjust the cooking time. Chicken thighs stay juicier and cook faster than breasts. Cut them into 1-inch pieces and bake for 20-25 minutes instead of 25-30 minutes. The skin adds flavor, but remove it if you prefer a cleaner bite. Thighs work especially well with the creamy sauce!
Why did my sauce turn grainy?
Grainy sauce usually happens when the roux cooks too long or isn't whisked enough. For smooth results, whisk constantly when adding the milk to the roux and keep heat at medium. If it happens, strain the sauce through a fine-mesh sieve before adding it to the pan. You can also blend the cooked sauce with an immersion blender for instant creaminess.
Can I make this dish with gluten-free pasta?
Yes, but test your gluten-free pasta first—it cooks faster and absorbs sauce differently. Use 10 oz gluten-free pasta instead of 12 oz and add 2 extra tablespoons milk to the sauce to compensate. Also, check the package for cooking time—gluten-free pasta often needs 1-2 minutes less than regular pasta.
