Ingredients

- 1 jar (24 ounces) spaghetti sauce
- 8 ounces cream cheese, softened
How to Make 4-Ingredient Million Dollar Spaghetti
Step 1: Cook the Spaghetti
Preheat your oven to 375°F (190°C).
Bring a large pot of salted water to a boil. Cook the spaghetti according to the package directions until just al dente.
Drain well and set aside.
Step 2: Prepare the Meat Sauce
While the spaghetti cooks, brown the ground beef in a large skillet over medium-high heat.
Break the beef apart as it cooks until no longer pink. Drain any excess grease.
Stir in the spaghetti sauce and simmer for a few minutes until heated through.
Step 3: Combine the Cream Cheese and Spaghetti
Place the drained spaghetti in a large bowl.
Add the softened cream cheese and toss until the cream cheese is distributed throughout the warm pasta.
The heat from the spaghetti will help soften and coat the noodles.
Step 4: Layer the Casserole
Lightly grease a 9×13-inch baking dish.
Spread about half of the creamy spaghetti mixture into the bottom of the dish.
Spoon half of the meat sauce over the pasta.
Add the remaining spaghetti, followed by the remaining meat sauce.
Spread the top into an even layer.
Step 5: Bake
Cover the baking dish loosely with aluminum foil and bake for about 25 minutes.
Remove the foil and bake for another 10 to 15 minutes, until the casserole is hot and bubbling around the edges.
Let it rest for about 5 to 10 minutes before slicing and serving.
Tips for the Best Million Dollar Spaghetti
Don’t Overcook the Pasta
Cook the spaghetti just until al dente. It will continue cooking in the oven, and starting with very soft pasta can result in a mushy casserole.
Soften the Cream Cheese
Let the cream cheese soften before mixing it with the spaghetti. This makes it much easier to distribute evenly.
Drain the Beef
Removing excess grease keeps the finished casserole from becoming oily.
Let It Rest
Allow the baked spaghetti to rest for several minutes before serving. This helps the layers settle and makes the casserole easier to portion.
Easy Variations
Add Italian Sausage
Replace some or all of the ground beef with Italian sausage for a richer, more savory flavor.
Add Mozzarella
For an extra-cheesy casserole, sprinkle shredded mozzarella over the top before baking.
Add Parmesan
A little grated Parmesan gives the finished dish a delicious savory finish.
Add Vegetables
Sautéed mushrooms, diced onions, bell peppers, or spinach can easily be added to the meat sauce.
Use Ground Turkey
Ground turkey can replace the ground beef for a lighter variation.
What to Serve With Million Dollar Spaghetti
This casserole is hearty enough to be a complete meal, but it pairs wonderfully with simple sides such as:

- Caesar salad
- Steamed broccoli
- Green beans

Make-Ahead Instructions
Million dollar spaghetti is an excellent make-ahead casserole.
Assemble the casserole according to the recipe, cover it tightly, and refrigerate for up to 24 hours before baking.
When ready to bake, allow the dish to sit at room temperature for a short time while the oven preheats. You may need to add a few extra minutes to the baking time if the casserole is cold from the refrigerator.
How to Store Leftovers
Store leftover spaghetti in an airtight container in the refrigerator for up to 3 to 4 days.
Reheat individual portions in the microwave or warm larger portions in a covered baking dish in the oven.
Can You Freeze Million Dollar Spaghetti?
Yes. Assemble the casserole in a freezer-safe baking dish, cover it tightly, and freeze before baking.
For best quality, use within about 2 months.
Thaw overnight in the refrigerator before baking. Add extra baking time if needed until the center is hot.
