Ingredient Breakdown

Ground Beef (1 lb): Provides the hearty base for the casserole, adding protein and rich flavor. You can also use ground turkey, chicken, or Italian sausage.
Spaghetti Sauce (1 jar, 24 oz): Saves time and adds depth. A good marinara or your favorite pasta sauce makes this dish shine.
Cream Cheese (8 oz, softened): Creates a velvety, creamy texture that sets this casserole apart from regular baked spaghetti.
Sour Cream (¼ cup): Adds tanginess and helps lighten the cream cheese mixture.
Cottage Cheese (1 cup/½ lb): Gives body to the cheese layer while keeping it light and fluffy. Ricotta can be used as a substitute.
Butter (1 stick/½ cup): Laid at the bottom of the dish, it melts into the pasta, infusing it with richness and preventing sticking.
Spaghetti Noodles (1 lb): The foundation of the casserole. Cooking them al dente ensures they don’t get mushy when baked.
Mozzarella Cheese (2 cups shredded): Melts beautifully to create a gooey, golden top layer.
Salt and Pepper (to taste): Essential seasonings to balance the flavors.
Parsley (optional garnish): Adds a fresh pop of color and brightness to the final dish.

Pro Tips

Cook pasta al dente: Slightly undercooked pasta holds up better during baking.
Drain meat well: Removing excess fat prevents the casserole from becoming greasy.
Soften cream cheese fully: Room-temperature cream cheese ensures a smooth, lump-free mixture.
Layer carefully: Spreading the cheese mixture evenly helps every bite taste balanced.
Rest before serving: Allowing the casserole to sit for 5–10 minutes helps it slice neatly and keeps layers intact.

Ingredient Swaps or Variations

Different protein: Use Italian sausage, ground turkey, or even a veggie substitute.
Spice it up: Add red pepper flakes, jalapeños, or a spicy marinara.
Cheese alternatives: Swap mozzarella for provolone, fontina, or cheddar for a new twist.
Veggie boost: Mix in spinach, zucchini, or mushrooms to sneak in extra vegetables.
Gluten-free version: Use gluten-free spaghetti and double-check that your sauce is gluten-free.

Serving Suggestions

Million Dollar Spaghetti Casserole is a meal in itself, but pairing it with the right sides makes dinner extra special.

Classic side salad: A crisp Caesar or garden salad balances the richness.
Garlic bread or breadsticks: Perfect for soaking up extra sauce.
Roasted vegetables: Asparagus, broccoli, or zucchini add freshness.
