Tips for the Best Million Dollar Spaghetti Casserole:

Cook Pasta to Al Dente: Cooking the spaghetti to an al dente texture prevents it from becoming mushy after baking.
Use Freshly Grated Cheese: Freshly grated cheese melts better and has a richer flavor than pre-shredded varieties.
Layer Butter Evenly: Slicing and layering butter ensures the casserole is rich and moist throughout.
Let it Cool Before Serving: Allowing the casserole to sit for a few minutes after baking helps it set and makes serving easier.

Variations:

Make this dish your own with a few simple changes:

Swap Cottage Cheese for Ricotta: If you prefer a slightly sweeter, creamier layer, substitute cottage cheese with ricotta.
Add Vegetables: Sautéed mushrooms, bell peppers, or spinach can be added to the beef layer for extra flavor and nutrition.
Use Italian Sausage: Swap ground beef for Italian sausage for a spicier, more flavorful version.
Try Different Cheeses: Mix mozzarella or Parmesan with the cheddar for a unique twist on the cheesy topping.

Storage and Reheating:

Million Dollar Spaghetti Casserole is great for leftovers, and it reheats beautifully.

Refrigerate: Store leftovers in an airtight container in the refrigerator for up to 3 days.
Freeze: For longer storage, wrap individual portions or the entire casserole in foil, then place in a freezer-safe bag or container for up to 2 months. Thaw in the refrigerator overnight before reheating.
Reheat: Warm individual portions in the microwave, or reheat the entire casserole in a 350°F oven for 20-25 minutes until heated through.
