Beef Alfredo Casserole Recipe: One-Pan Creamy Pasta Bake with Crispy Top

This beef alfredo casserole recipe delivers restaurant-quality comfort food with crispy golden edges and creamy alfredo sauce in one pan. The secret lies in browning the beef first—this creates deep, savory flavor that infuses every forkful of tender pasta and rich sauce. I developed this recipe during a particularly busy week when I needed a meal that felt indulgent but required minimal effort, and it became an instant family favorite.

The beauty of this dish is its simplicity: ground beef, pasta, and a velvety alfredo sauce come together in a single baking dish, creating a meal that's hearty enough for a weeknight dinner but impressive enough for company. The crispy top forms as the cheese melts and browns under the broiler, while the alfredo sauce remains luscious and clings perfectly to the pasta. This recipe is designed to be foolproof, with clear steps that ensure consistent results every time.

By the time it emerges from the oven, you'll have a creamy, cheesy casserole with a golden, crispy crust that's impossible to resist. The beef stays tender and flavorful, the pasta is perfectly cooked, and the sauce is rich without being overly heavy. Each bite delivers a perfect balance of textures and flavors, making this dish a standout for any occasion. Serve with a simple side salad or garlic bread to complete the meal.

What sets this recipe apart is the way the flavors meld together during baking, creating a dish that's more than just the sum of its parts. The alfredo sauce becomes even more velvety as it absorbs the flavors of the beef and pasta, while the crispy top adds a satisfying contrast. This is the kind of meal that tastes like it took hours to prepare, even though it comes together in under an hour.

Ingredients for beef alfredo casserole

Ground beef, pasta, and rich cream come together for a one-pan alfredo masterpiece.

The beef makes this dish—80% lean or leaner gives you the perfect balance of flavor and tenderness. Costco or Walmart usually have great prices on ground beef, and I always grab the pre-ground chuck for this recipe. Look for bright red color and good marbling if you're buying a whole package to grind yourself. The shallots? Trader Joe's sells them pre-minced, which saves time, but chopping your own gives you more control over the texture. Freshly grated Parmesan is non-negotiable here—pre-grated gets clumpy and lacks that sharp, salty punch that balances the creaminess.

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 adds a nice tang. The pasta needs to be broken in half—this ensures it cooks evenly and fits perfectly in your baking dish. If you're using a 9x13-inch dish, 12 oz of fettuccine is ideal, but adjust slightly if your dish is larger or smaller. For extra richness, I sometimes add a splash of white wine to the sauce, but it's not required. The red pepper flakes can be skipped entirely if you prefer no heat.

This casserole reheats beautifully—4-5 days in the fridge, 3 months frozen. I always make a double batch because leftovers are just as good (if not better) the second day. Store it covered with foil to keep the top from drying out. When reheating, cover with foil for the first 10 minutes to melt the cheese evenly, then uncover to crisp the top under the broiler. The crispy edges are worth the extra minute under the broiler—don't skip this step!

Step-by-step instructions for beef alfredo casserole

Here's how to create a rich, creamy pasta bake with a perfectly crispy top every time.

Heat 2 tablespoons butter in a large oven-safe skillet over medium-high heat. Add the 1.5 lb ground beef and cook, breaking it apart with a wooden spoon, until it loses its raw color and begins to brown—about 5-6 minutes. This step develops deep flavor through the Maillard reaction, so don't rush it.

Once the beef is fully browned, drain any excess fat (leave about 1 tablespoon for flavor). Add the 0.5 cup finely chopped shallot and 4 cloves minced garlic, cooking for 2-3 minutes until fragrant. Stir in the 2 tablespoons all-purpose flour and cook for another 1 minute to remove any raw taste. This creates a proper roux that will thicken your sauce beautifully.

Pour in the 1.5 cups heavy cream and 1.5 cups beef broth, stirring constantly to prevent lumps from forming. Bring the mixture to a gentle simmer over medium heat, then reduce heat to low and let it cook for 5 minutes until slightly thickened. This simmering step ensures the sauce develops proper body without becoming gluey.

Remove the skillet from heat and stir in the 1.5 cups freshly grated Parmesan cheese, 1.5 teaspoons salt, 0.5 teaspoon black pepper, 1 teaspoon dried thyme, and 0.5 teaspoon red pepper flakes (if using). The cheese should melt completely into the sauce, creating a velvety texture. If the sauce is too thick, whisk in 1-2 tablespoons hot water to achieve a smooth, pourable consistency.

While the sauce simmers, cook the 12 oz fettuccine pasta in a separate pot of salted boiling water until al dente (about 2 minutes less than package instructions). Drain the pasta and immediately add it to the skillet with the sauce, tossing gently to coat every strand. The residual heat will finish cooking the pasta while absorbing the creamy sauce.

Transfer the skillet to a preheated 375°F oven. Sprinkle the 2 cups shredded mozzarella cheese evenly over the top, creating a thick, even layer. The cheese will melt and create that coveted crispy crust we're after. Place the skillet on the middle rack to ensure even baking.

Bake for 15-20 minutes until the top is deep golden brown and bubbly. You'll know it's ready when the cheese has set into a crispy layer that resists gentle pressure with a spoon. If the top browns too quickly, tent loosely with aluminum foil to prevent burning while allowing the cheese to melt completely.

The casserole is done when the internal temperature reaches 165°F and the edges pull away slightly from the skillet. Let it rest for 5 minutes before serving—this allows the cheese to set properly and makes slicing easier. The result should be a creamy, rich pasta bake with a satisfyingly crispy top that contrasts beautifully with the velvety sauce beneath.

Wine and beer pairings for this dish

Rich Red Wine

A bold Chianti Classico or Sangiovese from Tuscany is my go-to pairing for this creamy casserole. The medium-bodied red wine's acidity cuts through the richness of the alfredo sauce while its earthy notes complement the savory beef beautifully. Look for a wine with 13-14% alcohol—this range balances the dish's creaminess without overpowering it. Serve slightly chilled to enhance its freshness against the warm casserole. 🍷

Creamy White Options

For those who prefer white wine, a Chardonnay with noticeable oak aging works wonders. I recommend a California Chardonnay like Kendall-Jackson or La Crema, which have enough body to stand up to the dish. The buttery notes in these wines mirror the alfredo sauce's creaminess, while their acidity keeps your palate refreshed. Avoid overly oaky whites—they can make the dish taste heavier. 🥂

Crisp Italian Lager

If you're serving this to a crowd with mixed preferences, a Peroni or Birra Moretti Italian lager provides a refreshing contrast. The crisp, slightly bitter finish cleanses your palate between bites of creamy pasta. For a craft option, try a Belgian witbier like Stella Artois Wit, which adds a citrusy brightness that pairs surprisingly well with the dish's richness. Serve these beers well-chilled at 38-40°F for optimal enjoyment. 🍺

Dessert Wine Surprise

Here's a fun twist: a small glass of Moscato d'Asti or Prosecco can be a delightful palate cleanser before or after the meal. The light effervescence and sweetness of these Italian sparkling wines complement the dish's creamy, cheesy notes. I like to serve a 4-ounce pour chilled to 45°F—it's unexpected but works beautifully with the rich flavors. 🥂

Avoid These Pairings

Skip heavy reds like Cabernet Sauvignon or Syrah—their tannins clash with the creamy sauce. Avoid sweet wines too, as their sugar can make the dish taste overly rich. Even though this is a comfort food, you want your wine to enhance, not overpower, the meal. The right pairing should make each bite taste even better than it already is. 💫
