Ingredients

• 12 ounces spaghetti
• 1 pound ground beef
• 1 jar (24 ounces) marinara or spaghetti sauce
• 8 ounces cream cheese, softened

The four main ingredients are: spaghetti, ground beef, pasta sauce, and cream cheese.

Optional pantry seasonings such as salt, black pepper, or garlic powder can be added to taste.

How to Make 4-Ingredient Million Dollar Spaghetti

1. Cook the Spaghetti

Preheat the oven to 375°F (190°C).

Bring a large pot of water to a boil and cook the spaghetti until just al dente, following the package directions.

Drain well. Avoid overcooking the pasta because it will continue cooking in the oven.

2. Brown the Ground Beef

While the spaghetti cooks, place the ground beef in a large skillet over medium-high heat.

Cook until browned and no longer pink, breaking the beef into small crumbles as it cooks.

Drain off excess grease.

3. Make the Meat Sauce

Pour the marinara sauce into the skillet with the cooked ground beef.

Stir well and simmer for about 3–5 minutes, just until everything is hot and combined.

4. Make the Creamy Spaghetti

Place the drained spaghetti in a large bowl while it’s still warm.

Add the softened cream cheese and toss until the cream cheese melts and evenly coats the spaghetti.

If necessary, add a spoonful of warm pasta water to help distribute the cream cheese.

5. Assemble the Casserole

Lightly grease a 9×13-inch baking dish.

Spread half of the creamy spaghetti across the bottom.

Spoon half of the beef and marinara mixture over the pasta.

Add the remaining spaghetti and finish with the remaining meat sauce.

6. Bake

Cover loosely with foil and bake for 20 minutes.

Remove the foil and continue baking for another 10–15 minutes, until the casserole is bubbling around the edges and thoroughly heated.

Because the beef was cooked before assembly, the baking stage brings the layers together and develops the rich, creamy texture.

7. Rest and Serve

Remove the casserole from the oven and let it rest for about 5–10 minutes before serving.

Cut or scoop generous portions onto plates and serve warm.

Tips for the Best Million Dollar Spaghetti

Cook the spaghetti only until al dente. Slightly firm pasta holds its texture much better during baking.

Make sure the cream cheese is softened before mixing it with the spaghetti. This makes it easier to create an evenly creamy coating.

Drain the ground beef well before adding the marinara sauce so the casserole doesn’t become greasy.

Let the finished casserole rest briefly before serving. The layers will settle slightly and become easier to portion.

Easy Variations

If you don’t need to keep the recipe strictly four ingredients, sprinkle mozzarella or cheddar cheese over the top before baking for a bubbly cheese crust.

You can also add ricotta or cottage cheese for an even creamier filling.

Italian sausage can replace part or all of the ground beef for a stronger, more savory flavor.

Mushrooms, onions, bell peppers, or spinach are easy vegetable additions.

What to Serve With Million Dollar Spaghetti

This rich baked spaghetti pairs beautifully with garlic bread, Caesar salad, roasted broccoli, green beans, or a simple garden salad.

For an easy family dinner, garlic bread and a crisp green salad are all you need alongside the casserole.

How to Store Leftovers

Store leftover Million Dollar Spaghetti in an airtight container in the refrigerator for up to 3–4 days.

Reheat individual servings in the microwave or cover the casserole with foil and warm it in a 350°F (175°C) oven until heated through.

You can also freeze individual portions for up to 2–3 months. Thaw overnight in the refrigerator before reheating.

Frequently Asked Questions

Why is it called Million Dollar Spaghetti?

Million Dollar Spaghetti is the popular name for an extra-rich baked spaghetti casserole that typically combines pasta, meat sauce, and a creamy cheese layer. The name refers to its indulgent flavor rather than its cost.

Can I use another pasta?

Yes. Although spaghetti gives the recipe its classic appearance, linguine, bucatini, penne, or another sturdy pasta can work.

Can I make it ahead of time?
