What You’ll Need (Ingredients)

• 12 ounces pasta (penne, rotini, or ziti)
• 1 pound ground beef (85–90% lean)
• 1 small yellow onion, diced
• 3 cloves garlic, minced
• 2 cups heavy cream
• 1 cup whole milk
• 4 tablespoons unsalted butter
• 1/3 cup grated Parmesan (plus extra for topping)
• 1 cup shredded mozzarella
• 1/2 cup shredded provolone or Monterey Jack (optional but awesome)
• 2 tablespoons all-purpose flour
• 1 teaspoon Italian seasoning
• 1/2 teaspoon crushed red pepper flakes (optional)
• Salt and black pepper, to taste
• 2 tablespoons chopped fresh parsley (for garnish)
• Olive oil or cooking spray for the baking dish

How to Make It – Instructions

1. Preheat and prep: Heat oven to 375°F (190°C).

   Lightly oil a 9×13-inch baking dish.

2. Boil pasta: Cook pasta in salted water until just shy of al dente (about 1 minute less than package). Drain and set aside.
3. Brown the beef: In a large skillet over medium-high heat, cook ground beef with a pinch of salt and pepper until browned. Break it up as it cooks.
4. Sauté aromatics: Add diced onion to the beef and cook 3–4 minutes until softened.

   Stir in garlic for 30 seconds until fragrant. Remove excess fat if needed.

5. Build the roux: Reduce heat to medium. Add butter to the skillet.

   When melted, sprinkle in flour and stir for 1 minute to form a paste.

6. Make the Alfredo: Slowly whisk in cream and milk. Simmer gently 3–5 minutes until slightly thickened. Stir in Parmesan, Italian seasoning, and red pepper flakes.

   Taste and season with salt and pepper. The sauce should coat a spoon.

7. Combine: Add cooked pasta to the skillet and toss to coat. If your skillet is small, combine everything in a large bowl.

   Don’t be shy—get every noodle saucy.

8. Assemble: Transfer to the baking dish. Top evenly with mozzarella and provolone. Sprinkle extra Parmesan for a salty finish.
9. Bake: Bake 15–20 minutes until cheese is melted and edges are bubbling.

   For a golden top, broil 1–2 minutes at the end. Watch closely—no one likes charcoal chic.

10. Finish and serve: Rest 5 minutes, garnish with parsley, then serve hot. Prepare for compliments you absolutely deserve.

Storage Tips

• Fridge: Store leftovers in an airtight container up to 4 days.

  Reheat covered at 325°F until warm, or microwave in short bursts with a splash of milk to re-loosen the sauce.

• Freezer: Freeze baked or unbaked casserole (tightly wrapped) up to 2 months. Thaw overnight in the fridge.
• Reheat from frozen: Bake covered at 350°F until hot throughout, then uncover to re-crisp the top.

Nutritional Perks

• Protein-rich: Ground beef brings satiety and muscle-friendly protein.
• Calcium boost: Cheese and milk support bone health.
• Carb + fat synergy: Balanced energy for active days (or Netflix marathons—no judgment).
• Easy to tweak: Swap in lighter dairy, add veggies, or use whole-wheat pasta for more fiber, FYI.

What Not to Do

• Don’t overcook the pasta: It keeps cooking in the oven. Mushy noodles are a mood killer.
• Don’t skip seasoning: Taste the sauce.

  Bland Alfredo is a crime against comfort food.

• Don’t drown it in grease: Drain excess fat from the beef or the sauce will feel heavy.
• Don’t broil and walk away: Cheese goes from golden to “uh-oh” fast.
• Don’t use pre-shredded cheese only: If possible, grate some yourself. It melts better and tastes richer.

Different Ways to Make This

• Veggie-loaded: Stir in sautéed mushrooms, spinach, or roasted broccoli for color and nutrients.
• Spicy: Add diced jalapeños or swap mozzarella for pepper jack. A pinch of cayenne in the sauce works wonders.
• Bacon upgrade: Fold in crisp bacon bits for smoky depth.

  Is it necessary? No. Is it elite?

  Yes.

• Lightened up: Use half-and-half instead of heavy cream, leaner beef, and part-skim mozzarella. Still delicious, easier on the macros.
• Different protein: Ground turkey, Italian sausage, or a mix of beef and pork for extra flavor.
• Herb-forward: Add fresh basil and thyme with lemon zest for brightness to cut through the richness.
• Gluten-free: Use GF pasta and a cornstarch slurry instead of flour in the sauce (1 tablespoon cornstarch mixed with 2 tablespoons cold milk).

FAQ

Can I use jarred Alfredo sauce?

Yes. Use about 2 to 2 1/2 cups.

Warm it with the beef and aromatics so it marries with the flavors. If it’s too thick, thin with a splash of milk.

What pasta shape works best?

Short, ridged shapes like penne, rotini, or rigatoni hold the sauce and don’t fall apart. Long noodles turn into a tangled mess—hard pass.

How do I prevent a greasy casserole?

Use 85–90% lean beef, drain excess fat after browning, and avoid overloading with extra oil or butter.

Balance is key, IMO.

Can I make it ahead?

Totally. Assemble, cover, and refrigerate up to 24 hours. Bake covered for 10 minutes longer, then uncover to brown.

How do I keep the sauce creamy after reheating?

Add a splash of milk or cream, cover, and reheat gently.

Stir halfway. Creamy revival achieved.

What cheese combo melts best?

Mozzarella for melt, provolone or Monterey Jack for stretch, and Parmesan for salty umami. That trio hits the sweet spot.
