How to Make Million Dollar Spaghetti Casserole: Creamy, Cheesy & Totally Worth It Recipe
Step 1: Preheat and Prepare
Start by preheating your oven to 350°F (175°C). This ensures it’s ready to bake your layered masterpiece to a perfect golden bubbly finish as soon as you assemble all the components.
Step 2: Cook the Spaghetti
Boil your spaghetti in well-salted water until just al dente—about 12 minutes. This timing is crucial because the pasta will continue to cook in the oven, so you want it tender but still firm to the bite. Drain and set aside while you prepare the rest.
Step 3: Brown the Ground Beef
In a skillet over medium-high heat, brown the lean ground beef for 5 to 7 minutes until fully cooked and nicely browned. Drain excess grease and stir in the spaghetti sauce, letting the flavors meld while you move on to layering your casserole.
Step 4: Build the Butter Base Layer
In your 9×13-inch baking dish, place half the butter slices on the bottom. This might sound unusual, but it creates an indulgent buttery base that keeps the pasta moist and adds an incredible richness to every bite.
Step 5: First Pasta Layer
Spread half of the cooked spaghetti evenly over the butter slices. This layers your base with tender pasta, ready to be topped with the creamy cheese mixture for that signature texture contrast.
Step 6: Cream Cheese Layer
In a bowl, combine the cottage cheese, softened cream cheese, and sour cream until completely smooth. Spread this creamy mixture evenly over your spaghetti layer—this adds luscious richness and the creamy texture that makes this casserole truly stand out.
Step 7: Second Pasta Layer and Butter Dots
Add the remaining spaghetti in an even layer on top of the cream cheese spread, then dot it with the remaining butter slices. These butter pieces will melt during baking to create pockets of buttery goodness.
Step 8: Top with Beef Sauce
Spread the prepared ground beef and spaghetti sauce mixture evenly on top of the next pasta layer. This savory topping ensures every forkful bursts with meaty, saucy flavor, perfectly balanced against the creamy layers below.
Step 9: Bake and Cheese It Up
Bake the casserole uncovered for 30 minutes to let everything meld and heat through. Then sprinkle the shredded sharp cheddar on top and bake for an additional 15 minutes until the cheese is bubbly and golden. That golden crust is the delightful finishing touch that makes this Million Dollar Spaghetti Casserole: Creamy, Cheesy & Totally Worth It Recipe truly a showstopper.
How to Serve Million Dollar Spaghetti Casserole: Creamy, Cheesy & Totally Worth It Recipe

Garnishes
Freshly chopped parsley or basil sprinkled on top adds a burst of color and a hint of fresh herbal flavor that balances the richness. A light dusting of grated Parmesan can also elevate the cheese factor and add a subtle nutty note.
Side Dishes
This casserole is such a substantial meal that light, fresh sides like a crisp Caesar salad, steamed green beans, or roasted vegetables are perfect companions. They provide textural contrast and a fresh bite to go alongside the creamy, cheesy casserole.
Creative Ways to Present
For a fun twist, serve this casserole in individual ramekins for personalized portions. Alternatively, sprinkle a handful of toasted breadcrumbs or crushed garlic crackers on top before baking for an extra crunchy texture contrast that complements every bite.
Make Ahead and Storage
Storing Leftovers
Once cooled to room temperature, cover leftovers tightly with plastic wrap or transfer them to an airtight container. Refrigerate for up to 3 to 4 days. The flavors actually deepen after sitting overnight, making reheated slices even tastier.
Freezing
This casserole freezes beautifully! Prepare and bake it as directed, then cool completely. Wrap the dish securely in foil and plastic wrap or divide into freezer-safe containers. Freeze for up to 2 months. When ready to enjoy, thaw overnight before reheating.
Reheating
Reheat leftover casserole in the oven at 350°F (175°C) for about 20 minutes or until warmed through. To keep it moist, cover with foil during reheating. For quick meals, single servings reheat well in the microwave but may lose some crispiness on top.
FAQs
Can I substitute the ground beef with another protein?
Absolutely! Ground turkey, chicken, or even plant-based meat alternatives work great in this casserole. Just brown and season them as you would the beef for similar savory results.
Is it possible to make this casserole vegetarian?
Yes, you can skip the meat and add sautéed mushrooms, zucchini, or spinach instead. Use your favorite marinara sauce and consider adding extra cheese or beans for protein.
Can I prepare the casserole ahead of time before baking?
Definitely! Assemble all the layers in the baking dish, cover tightly, and refrigerate for up to 24 hours before baking. Baking time will be the same, but you might want to add a few extra minutes if baking straight from the fridge.
What type of spaghetti sauce works best?
Choose a sauce that you love—whether it’s classic marinara, a chunky tomato basil, or a flavorful garlic and herb blend. Since the sauce is a key flavor layer, use one with good taste and quality ingredients.
Can I use pre-shredded cheddar cheese?
Yes, pre-shredded cheddar works fine and saves time. Just be aware that freshly shredded cheese tends to melt better and may create a more luscious topping.
