This is the casserole that ends all casserole debates. We’re talking layers of tender pasta, seasoned ground beef, the creamiest sauce known to humanity, and enough melted cheese to make you question your life choices (in the best way). It’s like someone took all the comfort food greatest hits and smooshed them into one glorious baking dish that feeds a crowd and makes everyone ask for the recipe.
This is the kind of dish that shows up to potlucks and comes home with an empty pan and twelve new best friends. My neighbor’s mom, who’s been making casseroles since the dawn of time, tried this and was like “Well, I guess I have a new signature dish now.” That’s when you know you’ve struck gold – when you convert the casserole queens.

The Good Stuff You’ll Need
For the Base:
- 12 oz egg noodles or rotini pasta (whatever makes you happy)
- 1 lb ground beef (80/20 for maximum flavor)
- 1 medium onion, diced
- 3 cloves garlic, minced
- 1 packet (1 oz) onion soup mix (yes, the packet – don’t be a hero)
- 1 can (14.5 oz) diced tomatoes, drained
- 1 tsp Worcestershire sauce
- Salt and pepper to taste
For the Crazy Creamy Sauce:
- 8 oz cream cheese, softened (this is non-negotiable)
- 1 cup sour cream (full-fat, we’re not playing games)
- 1 cup mayonnaise (trust the process)
- 2 cups sharp cheddar cheese, shredded
- 1 cup mozzarella cheese, shredded
- 1/2 cup Parmesan cheese, grated
- 1 tsp garlic powder
- 1/2 tsp dried Italian seasoning
- 1/4 tsp cayenne pepper (optional but recommended)

- 2 tbsp butter, melted
- 2 tbsp fresh parsley, chopped (for pretending this is healthy)

Let’s Do This
Step 1: Pasta Party Prep
Preheat your oven to 350°F and grease a 9×13 baking dish like your life depends on it.
Cook pasta according to package directions until just barely al dente – it’ll finish cooking in the oven. Drain and set aside.
Pro tip: Save a cup of that starchy pasta water just in case your sauce needs loosening later.
Step 2: Beef Up the Flavor
In a large skillet over medium-high heat, cook the ground beef and onion until the beef is browned and the onion is soft (about 8 minutes).
Add garlic and cook for another minute until it smells incredible.
Stir in the onion soup mix, drained diced tomatoes, and Worcestershire sauce. Let it simmer for 5 minutes to let all those flavors get acquainted.
Season with salt and pepper, then remove from heat.
Step 3: The Sauce That Dreams Are Made Of
In a large bowl, mix the softened cream cheese, sour cream, and mayonnaise until smooth and creamy.
Add the 2 cups cheddar, mozzarella, Parmesan, garlic powder, Italian seasoning, and cayenne. Stir until everything is combined and gorgeous.
If it seems too thick, add a splash of that reserved pasta water to loosen it up.
Step 4: Assembly Time (The Best Part)
In your greased baking dish, layer half the cooked pasta, then half the beef mixture.
Spread half the creamy cheese sauce over this layer.
Repeat with remaining pasta, beef, and sauce. Spread that top layer of sauce evenly – this is what’s going to get all golden and bubbly.
Step 5: The Golden Crown
Mix the topping ingredients: 1 1/2 cups cheddar, panko breadcrumbs, melted butter, and parsley.
Sprinkle this mixture evenly over the top of your casserole masterpiece.
Step 6: Bake Until Bubbly Perfection
Cover with foil and bake for 30 minutes.
Remove the foil and bake for another 15-20 minutes until the top is golden brown and the edges are bubbling like crazy.
Let it rest for 10 minutes before serving – I know it’s torture, but it needs to set up so it doesn’t fall apart when you serve it.
Serving Suggestions
- Perfect with a simple green salad and some crusty bread
- Great alongside steamed broccoli to pretend you’re being healthy
- Pairs beautifully with a glass of red wine or a cold beer
- Ideal for potlucks, family gatherings, or when you need to feed a crowd
Switch It Up
Veggie Power: Add diced bell peppers, mushrooms, or zucchini to the beef mixture.
Chicken Instead: Use rotisserie chicken or ground turkey instead of beef.
Spice It Up: Add diced jalapeños or use pepper jack cheese in the sauce.
Lighter Version: Use Greek yogurt instead of some of the sour cream and mayo (but honestly, why would you?).
Mexican Vibes: Add taco seasoning to the meat and use Mexican cheese blend.
Make-Ahead Tips
This entire casserole can be assembled up to 2 days ahead – just cover tightly and refrigerate.
If baking from cold, add an extra 15-20 minutes to the covered baking time.
Freezes beautifully for up to 3 months – thaw overnight before baking.
Individual portions freeze great too for quick weeknight dinners.
Leftovers keep for 5 days in the fridge and reheat like a dream.

Questions People Actually Ask
Q: Can I use different pasta shapes?
A: Absolutely! Any short pasta works great. Avoid long noodles like spaghetti – they’re annoying in casseroles.
Q: What if I don’t have onion soup mix?
A: Mix 2 tbsp dried minced onion, 1 tsp onion powder, 1 tsp garlic powder, and 1/2 tsp salt.
Q: My sauce seems too thick – help!
A: Add a splash of milk, broth, or that reserved pasta water until it’s creamy and spreadable.
Q: Can I make this without mayonnaise?
A: You can use all sour cream instead, but the mayo adds a special tanginess that makes it amazing.
Q: How do I know when it’s done?
A: The edges should be bubbling, the top should be golden brown, and a knife inserted in the center should come out hot.
