Ingredients
Serves 6 people
• 1 pound penne pasta • 6 tablespoons unsalted butter • 6 tablespoons all-purpose flour • 3 cups whole milk, room temperature • ½ cup heavy cream, room temperature • 1 cup grated Parmesan cheese, divided • 3 cloves garlic, minced • ½ teaspoon Italian seasoning • ¼ teaspoon white pepper • ⅛ teaspoon nutmeg • Salt to taste • 1½ cups shredded mozzarella cheese, divided • ½ teaspoon garlic powder • 2 tablespoons fresh parsley, chopped • 1 tablespoon fresh basil, chopped • 1 tablespoon lemon juice • 6 ounces frozen spinach, thawed and drained (optional) • ½ cup sun-dried tomatoes, chopped (optional) • 1 cup panko breadcrumbs • 3 tablespoons melted butter • ¼ cup grated Parmesan cheese (for topping) • 2 tablespoons fresh thyme, chopped • 2 tablespoons reserved pasta water
Step-by-Step Instructions
Prepare Your Equipment and Ingredients
First, preheat your oven to 350 degrees Fahrenheit. Butter an 8-by-10-inch or 9-by-13-inch baking dish generously, ensuring the entire bottom and sides are well coated to prevent sticking and encourage even browning. Measure out all your ingredients before beginning, allowing the milk and cream to come to room temperature—this is crucial because cold dairy can cause your Alfredo sauce to break or become grainy when combined with hot ingredients. Having everything prepared and ready is the professional secret that transforms cooking from stressful to smooth and enjoyable.
Cook the Penne
Bring a large pot of salted water to a rolling boil. Add the penne and cook according to package directions until just al dente, meaning the pasta should have a slight firmness when bitten but not be hard or undercooked. Remember that the pasta will continue cooking in the oven, so slightly undercooking at this stage ensures it remains perfectly tender after baking. Drain the pasta in a colander and set it aside, but do not rinse it—the starch on the surface helps the Alfredo sauce adhere beautifully to each piece.
Create the Roux Foundation
Meanwhile, melt the butter in a large, heavy-bottomed saucepan over medium heat. Once the butter foams and becomes fragrant, sprinkle in the flour gradually while whisking constantly to combine thoroughly. Continue cooking and whisking for approximately two to three minutes to create a smooth paste, which is called a roux. The roux should smell toasted and nutty, not raw or floury, indicating that the flour has cooked properly. This foundational step is essential because it gelatinizes the flour starch, allowing the sauce to thicken properly when the liquid is added.
Build the Creamy Sauce
Slowly pour in the room-temperature milk while whisking constantly to prevent lumps from forming. Take your time with this step, adding the milk gradually and ensuring each addition is fully incorporated before adding more. Once all the milk is incorporated, add the heavy cream and the minced garlic, continuing to whisk until the mixture is smooth and uniform. Bring the sauce to a gentle simmer over medium heat, stirring frequently with a wooden spoon or whisk for approximately eight to ten minutes until the mixture thickens enough to coat the back of a spoon.
Season the Alfredo
Remove the saucepan from heat and allow it to cool for approximately two minutes. Next, gradually add three-quarters cup of Parmesan cheese in two batches, stirring gently after each addition until the cheese melts completely and incorporates smoothly into the sauce. The residual heat will melt the cheese without requiring additional cooking. Subsequently, add Italian seasoning, white pepper, nutmeg, salt, and garlic powder, stirring until everything is well combined and evenly distributed. Taste the sauce and adjust seasoning as needed—remember that additional Parmesan will be added to the topping, so season conservatively at this stage.
Combine Pasta and Sauce
Add the cooked, drained penne to the creamy Alfredo sauce, folding gently but thoroughly with a spatula or wooden spoon until every piece becomes evenly coated. Next, stir in three-quarters cup of mozzarella cheese, fresh parsley, fresh basil, lemon juice, and the optional spinach and sun-dried tomatoes if using them. Mix gently until all ingredients are evenly distributed and everything is well combined. The mixture should look creamy and luxurious, with pasta coated throughout. If using spinach, squeeze it very dry before adding to prevent excess moisture in the final dish.
Transfer to Baking Dish
Pour the creamy penne mixture into the prepared baking dish, spreading it evenly across the bottom and smoothing the surface with a spatula. The dish can be prepared up to this point and refrigerated, covered, for up to twenty-four hours before baking—simply add approximately ten minutes to the baking time if baking from cold. If baking immediately, allow the assembled dish to sit at room temperature for approximately five minutes while you prepare the topping.
Prepare the Crispy Topping
In a medium bowl, combine the panko breadcrumbs with the melted butter, stirring until the breadcrumbs are evenly moistened and resemble wet sand. This ensures the topping becomes golden and crispy rather than dry and pale during baking. Add the remaining three-quarters cup of mozzarella cheese, the quarter cup of Parmesan cheese for topping, and fresh thyme to the breadcrumb mixture, stirring to combine evenly. Sprinkle this mixture generously and evenly over the top of the penne, creating a thick, uniform layer that will become golden and deliciously crunchy when baked.
Bake Until Golden
Place the baking dish in the preheated 350-degree Fahrenheit oven and bake for approximately thirty to thirty-five minutes until the top is golden brown and crispy, and the sauce is bubbling around the edges. The Baked Penne Alfredo is perfectly done when you can see small bubbles breaking through the breadcrumb topping and the edges are bubbly but not burnt. If the top isn’t browning quickly enough, increase the oven temperature to 375 degrees during the final ten minutes of baking.
Rest Before Serving
Allow the Baked Penne Alfredo to rest for approximately five to ten minutes after removing it from the oven. This resting period allows the sauce to set slightly, making serving cleaner and preventing the dish from being too soupy. The internal temperature should still be hot, and the Alfredo sauce should remain creamy and delicious while achieving the perfect consistency for plating and presentation.
Serve with Pride
Using a large spoon or spatula, serve the Baked Penne Alfredo directly from the baking dish, ensuring each portion includes plenty of the crispy breadcrumb topping along with the creamy pasta. Alternatively, you can portion it into individual serving bowls for a more elegant presentation that feels restaurant-quality. Serve immediately while everything is hot and the contrast between the crispy top and creamy sauce is at its most pronounced and delicious.
Serving and Storing Tips
Serving Suggestions
This luxurious dish pairs beautifully with simple roasted vegetables such as broccoli, asparagus, or roasted Brussels sprouts, which provide a fresh, slightly bitter contrast to the rich Alfredo sauce. Next, serve alongside a crisp green salad dressed with a tangy vinaigrette to balance the creaminess of the main dish. Additionally, garlic bread or crusty Italian bread makes an excellent accompaniment for soaking up any remaining sauce on the plate. For entertaining, present the Baked Penne Alfredo as a stunning centerpiece, allowing guests to admire the beautiful golden top before enjoying generous portions. This sophisticated dish works equally well for casual family dinners as it does for formal dinner parties where you want to impress guests with minimal stress.
Storage and Reheating Tips
Store leftover Baked Penne Alfredo in an airtight container in the refrigerator for up to four days. To reheat, transfer individual portions or the entire baking dish to a 350-degree Fahrenheit oven, covered with foil, for approximately fifteen to twenty minutes until warmed through and hot. Alternatively, individual portions can be reheated in the microwave, loosely covered, for two to three minutes, though oven reheating produces superior results and prevents the sauce from becoming watery or separated. This casserole also freezes beautifully for up to three months—assemble the baking dish completely before baking, wrap it tightly with plastic wrap and foil, then bake from frozen, adding approximately fifteen to twenty minutes to the baking time. Thawing is not necessary when baking from frozen, making this perfect for advance meal preparation and busy weeks.
Helpful Notes and Tips
Ingredient Substitutions and Flexibility
One of the greatest advantages of this recipe is its adaptability to different preferences, dietary restrictions, and ingredient availability. First, if you don’t have heavy cream, substitute with additional whole milk, though the sauce will be slightly less rich and luxurious. Additionally, you can replace some of the Parmesan with Asiago, Fontina, or Gruyère cheese for different flavor profiles and greater complexity. For a lighter version, use half-and-half instead of heavy cream and milk, or substitute up to half the milk with vegetable or chicken broth. Furthermore, if you’re dairy-free, use dairy-free butter, milk, and cheese alternatives for similar results, though the texture will differ slightly from the original.
Vegetable and Protein Additions
Feel free to customize this dish by adding your favorite vegetables and proteins to personalize it for your family’s preferences. Next, cooked chicken, shrimp, or crispy bacon pieces all work beautifully mixed into the pasta mixture before baking. Additionally, mushrooms, broccoli florets, roasted red peppers, artichoke hearts, or caramelized onions add nutrition and flavor without overwhelming the delicate Alfredo sauce. For a vegetarian version, simply focus on vegetables and omit any meat products—the dish remains incredibly satisfying and genuinely delicious.
Time-Saving Tips
Purchase pre-shredded cheese from your grocery store if you’re short on time, though freshly shredded cheese creates a creamier sauce with better melting texture. Additionally, prepare the entire baking dish in the morning and refrigerate it, covered, until dinner time, then simply pop it in the oven without thawing—just add approximately ten minutes to the baking time. Furthermore, you can make the Alfredo sauce ahead and refrigerate it for up to two days, then gently reheat and combine with fresh pasta and vegetables when ready.
Common Mistakes to Avoid
One frequent error involves cooking the pasta too long initially, which results in mushy, overcooked Baked Penne Alfredo—remember that the pasta continues cooking in the oven, so slightly undercooking is essential. Another common mistake is adding cold milk to the hot roux, which creates lumps and an unpleasant grainy texture—always use room-temperature or warm milk for a smooth, silky sauce. Additionally, avoid overmixing when combining the pasta and sauce; gentle folding preserves the tender pasta texture better than vigorous stirring. Finally, don’t skip the resting period after baking, as this allows the sauce to set properly and makes serving infinitely cleaner and more enjoyable.
Chef Tips for Excellence
First, the secret to an impossibly creamy sauce lies in using room-temperature milk and cream, which prevents the sauce from breaking or becoming grainy when the cheese is added. Second, reserve a portion of the Alfredo sauce before mixing with pasta; drizzle it over the breadcrumb topping for extra richness and a more indulgent final presentation.
