Notes
Storage:This Million Dollar Spaghetti recipe can be stored in an airtight container for up to 3 days. It can also be frozen in a sealed container for up to 3 months. If I'm going to freeze the entire recipe, I freeze it in this lasagna pan (affiliate link) then seal it with Glad Press n' Seal (affiliate link) before I put the cover on the pan to freeze.
Simply bring million-dollar spaghetti casserole out of the freezer the night before and let it defrost (preferably in the fridge). Ideally, you want to keep it at room temperature for about 30 minutes to an hour before you put it in the oven.
Then heat the oven to 350 degrees F/175 degrees C, remove the lid and plastic wrap, then tightly seal your casserole dish with aluminum foil (shiny side in) and put it in the oven for 20 - 30 minutes, until it's warmed through. *you can remove the foil and broil it for the final 2 minutes if you desire.
Cook the pasta just until al dente. This prevents it from becoming mushy during baking, especially since it will continue cooking in the oven.
Drain the meat mixture thoroughly before layering. Excess moisture can make the casserole watery and/or greasy, so make sure to drain any grease or liquid from the skillet.
Use part-skim or light cheeses to reduce fat without sacrificing flavor. These options still melt well and maintain a creamy texture but keep the dish healthier.
Layer ingredients evenly for consistent texture in every bite. Spread each layer to the edges of the dish so each serving gets the full flavor combo.
Let the casserole rest before cutting into it. Allowing it to sit for 10–15 minutes after baking helps it firm up and hold its shape better when served.
Add a little pasta water to your sauce if it's too thick. This trick loosens the sauce without diluting flavor and helps it cling better to the noodles.
Use a high-protein pasta to increase the nutritional value. Lentil, chickpea, or other legume-based pastas are great for boosting protein and fiber.
Make it ahead for easy weeknight meals. Assemble it the day before, refrigerate, and bake when ready. You may need to add a few extra minutes of baking time if it's cold from the fridge.
Sprinkle fresh basil or parsley on top before serving for added flavor and color. Fresh herbs brighten up the dish and give it a more finished, restaurant-style feel.
