Million Dollar Spaghetti Casserole – Creamy, Cheesy Baked Spaghetti
If you love a hearty pasta dinner with plenty of cheese, this Million Dollar Spaghetti Casserole is a wonderful way to turn everyday ingredients into a comforting family meal. Layers of tender spaghetti, rich beef and tomato sauce, and a creamy three-cheese filling come together under a golden layer of melted cheddar.
Think of it as a delicious cross between traditional spaghetti bolognese and a creamy baked pasta casserole. You still get the familiar combination of spaghetti and savoury minced beef, but the addition of cream cheese, sour cream and cottage cheese gives every portion a rich, velvety middle layer.
What I particularly like about this baked spaghetti casserole is how straightforward it is to assemble. You cook the pasta, brown the beef, prepare the creamy cheese mixture and layer everything in a 9 × 13-inch baking dish.
Then the oven does the rest. After 30 minutes of baking, you add grated cheddar and return the dish to the oven for another 15 minutes until the cheese melts.
The result is a satisfying, cheesy spaghetti bake that’s ideal for family dinners, weekend comfort food or occasions when you want something a little more indulgent than ordinary spaghetti.

Million Dollar Spaghetti Ingredients
You’ll need the following ingredients:
- 1 lb ground beef (approximately 450 g beef mince)
- 1 jar spaghetti sauce
- 8 oz cream cheese (approximately 225 g)
- ¼ cup sour cream
- ½ lb cottage cheese (stated as 1 cup in the original recipe)
- ½ cup butter (1 stick)
- 1 package spaghetti, 16 oz (approximately 450 g)
- Grated cheddar cheese, desired amount for topping
Important ingredient notes: The original recipe does not specify the volume or weight of the spaghetti sauce jar or the quantity of grated cheddar. The cottage cheese is listed as both ½ lb and 1 cup; these are the source’s stated measurements, although the exact volume-to-weight conversion depends on the product.
Ingredient Notes
Ground Beef (Beef Mince)
The recipe uses 1 lb of ground beef, known as beef mince in the UK.
Browning the beef before assembling the casserole gives the meat a savoury flavour and allows you to drain off excess fat.
Break it into small pieces as it cooks so the meat distributes evenly throughout the spaghetti sauce.
Spaghetti Sauce
One jar of spaghetti sauce provides the tomato-based sauce for the beef layer.
The original recipe doesn’t specify a jar size or particular flavour. A ready-made tomato pasta sauce is a convenient option for this style of casserole.
If you choose a strongly seasoned sauce, remember that it will influence the final flavour of the dish.
Cream Cheese
Eight ounces of cream cheese create the rich base of the creamy filling.
Its smooth texture helps bind the sour cream and cottage cheese together.
Sour Cream
A quarter cup of sour cream adds gentle tanginess to the filling.
In the UK, you may see this sold as soured cream.
Cottage Cheese
The recipe calls for ½ lb cottage cheese, also described as one cup in the original ingredient list.
Cottage cheese adds a mild, creamy texture and makes the filling more substantial.
It also gives the casserole a texture reminiscent of layered baked pasta dishes such as lasagne.
Butter
Half a cup of butter, equivalent to one standard US stick, is distributed in slices through the casserole.
The original method places some butter beneath the first spaghetti layer and more butter over the second spaghetti layer.
It doesn’t specify the exact number of slices for each layer.
Spaghetti
The recipe uses one 16-ounce package of spaghetti.
Cook it until al dente before assembling the casserole. This helps the pasta retain its texture during baking.
Grated Cheddar Cheese
Grated cheddar creates the melted topping.
The original recipe says to add the desired amount after the first 30 minutes of baking, then return the dish to the oven for 15 minutes.
Because no quantity is supplied, use your preferred amount rather than assuming a specific measurement.
Equipment You’ll Need
- 9 × 13-inch baking dish
- Large saucepan for cooking spaghetti
- Colander
- Large frying pan or skillet
- Mixing bowl
- Wooden spoon or spatula
- Knife for slicing butter
- Measuring cups
- Oven
- Serving spoon or spatula
The original recipe specifically uses a 9 × 13-inch baking dish, which gives you enough room to create the spaghetti and cheese layers.
How to Make Million Dollar Spaghetti Casserole
Follow these steps to create the original layered baked spaghetti dish.
-
Step 1: Preheat the Oven
Preheat your oven to 350°F (approximately 180°C).
Have your 9 × 13-inch baking dish ready for assembly.
-
Step 2: Cook the Spaghetti
Bring a large saucepan of water to the boil.
Cook the 16 oz spaghetti until al dente, meaning it should still have a little firmness when bitten.
Drain the pasta and set it aside until you’re ready to assemble the casserole.
-
Step 3: Prepare the Creamy Cheese Mixture
In a mixing bowl, combine:
- 8 oz cream cheese
- ¼ cup sour cream
- ½ lb cottage cheese (listed as 1 cup)
Mix until well blended.
Chef’s tip: Softened cream cheese is easier to combine smoothly. Allowing it to soften slightly before mixing is an optional preparation tip.
-
Step 4: Brown the Ground Beef
Cook the 1 lb ground beef in a frying pan until fully browned.
Break the beef into small pieces as it cooks.
Once cooked, drain away excess grease thoroughly.
-
Step 5: Add the Spaghetti Sauce
Combine the browned beef with the 1 jar of spaghetti sauce.
Stir until the meat is evenly coated in the tomato sauce.
-
Step 6: Start the First Layer
Place a few slices of the ½ cup butter into the bottom of the 9 × 13-inch baking dish.
Spread half of the cooked spaghetti over the butter.
-
Step 7: Add the Cream Cheese Filling
Spoon the cream cheese, sour cream and cottage cheese mixture over the first layer of spaghetti.
Spread it evenly so the pasta is covered.
-
Step 8: Add the Remaining Spaghetti
Place the rest of the cooked spaghetti over the creamy filling.
Spread it into an even layer.
-
Step 9: Add the Remaining Butter
Place a few more slices of butter over the second spaghetti layer.
Use the butter quantity supplied in the recipe, distributing it between the two butter layers.
-
Step 10: Add the Beef and Tomato Sauce
Pour the beef and spaghetti sauce mixture over the top of the noodles.
Spread it across the surface to cover the pasta.
-
Step 11: Bake for 30 Minutes
Place the assembled casserole in the preheated oven.
Bake for 30 minutes.
-
Step 12: Add the Cheddar Topping
After 30 minutes, remove the casserole carefully from the oven.
Sprinkle your desired amount of grated cheddar cheese evenly over the top.
-
Step 13: Bake for Another 15 Minutes
Return the dish to the oven for 15 minutes, allowing the cheddar to melt.
The total stated oven time is 45 minutes.
-
Step 14: Serve and Enjoy
Remove the casserole from the oven and serve.
Spoon generous portions onto plates, making sure each serving includes spaghetti, creamy filling, beef sauce and melted cheddar.
Understanding the Layers in Million Dollar Spaghetti
What makes this dish different from ordinary spaghetti is its layered structure.
Instead of simply mixing the pasta with the meat sauce, you build the casserole in stages.
Layer 1: Butter and Spaghetti
A few slices of butter go into the bottom of the baking dish, followed by half of the cooked spaghetti.
Layer 2: Creamy Cheese Filling
The mixture of cream cheese, sour cream and cottage cheese creates a rich centre.
This is the layer that gives Million Dollar Spaghetti its signature creamy texture.
Layer 3: More Spaghetti and Butter
The remaining spaghetti goes over the creamy filling, followed by more butter slices.
Layer 4: Beef and Tomato Sauce
The browned ground beef and spaghetti sauce mixture forms the savoury top layer before baking.
Layer 5: Melted Cheddar
After the casserole has baked for 30 minutes, grated cheddar goes over the top.
A final 15 minutes in the oven melts the cheese and completes the dish.
These layers create a delicious contrast between the rich cheese filling, savoury tomato sauce and tender spaghetti.
Expert Tips for the Best Baked Spaghetti Casserole
1. Cook the Pasta Al Dente
The spaghetti will continue cooking in the oven, so avoid making it too soft during boiling.
2. Drain the Spaghetti Well
Excess pasta water can make the creamy filling and sauce thinner than intended.
3. Soften the Cream Cheese Slightly
As an optional preparation tip, allow the cream cheese to soften a little before mixing it with the sour cream and cottage cheese.
4. Mix the Creamy Filling Thoroughly
Combining the three dairy ingredients well helps create an even filling layer.
5. Brown the Beef Completely
The original recipe cooks the beef before assembling the casserole.
6. Drain Excess Beef Fat
Draining the browned mince helps prevent the finished casserole from becoming greasy.
7. Divide the Spaghetti Evenly
Use half the spaghetti for the bottom layer and the rest above the cheese filling.
8. Spread the Creamy Layer Carefully
Try to distribute the filling evenly so every serving gets some of the creamy centre.
9. Follow the Butter Layering Method
The original recipe uses butter beneath the first spaghetti layer and over the second layer.
10. Add Cheddar at the Correct Time
Don’t add the cheddar topping before the initial 30-minute bake if you’re following the supplied instructions.
11. Use the Correct Baking Dish
A 9 × 13-inch dish provides the shape and capacity intended by the recipe.
12. Check the Centre Before Serving
Because the casserole contains a thick dairy filling, make sure it is thoroughly heated throughout before serving.
Common Mistakes to Avoid
Overcooking the Spaghetti Before Baking
Soft pasta may become mushy after another 45 minutes in the oven.
Skipping the Beef Draining Step
Excess grease can make the finished casserole heavy and oily.
Leaving the Cream Cheese Mixture Lumpy
Mix the cream cheese, sour cream and cottage cheese until well blended.
Mixing All the Layers Together
The original recipe uses a specific layering method to create a creamy centre.
Using All the Butter in One Layer
The recipe divides the butter between the bottom of the dish and the second spaghetti layer.
Adding the Cheddar Too Early
The cheddar goes on after the first 30 minutes of baking.
Assuming a Specific Sauce Jar Size
The original recipe calls for one jar of spaghetti sauce without specifying its weight or volume.
Assuming a Fixed Cheddar Quantity
The recipe leaves the amount of grated cheddar to your preference.
Optional Million Dollar Spaghetti Variations
The original recipe uses beef mince, spaghetti sauce, cream cheese, sour cream, cottage cheese, butter, spaghetti and cheddar. The ideas below are optional adaptations.
Extra Cheesy Spaghetti Casserole
Add a generous amount of grated cheddar to the topping, as the original recipe allows.
Spicy Baked Spaghetti
For a spicier version, you could add a pinch of dried chilli flakes to the beef sauce.
Italian Herb Version
As an optional adaptation, add a little dried oregano or Italian herb seasoning to the tomato sauce.
Vegetable-Loaded Version
You could add cooked mushrooms, peppers or spinach to the beef sauce.
Different Cheese Topping
Although the original recipe specifies cheddar, you could experiment with mozzarella for a different melted cheese texture.
Note: These are optional changes and are not included in the original ingredient list.
What to Serve with Million Dollar Spaghetti
This creamy baked spaghetti casserole is hearty enough to serve as a main course. A simple side dish can help balance its richness.
Garlic Bread
Warm garlic bread is a classic pairing for tomato-based pasta dishes.
Green Salad
A crisp salad with a light dressing brings freshness alongside the creamy cheese layers.
Steamed Broccoli
Broccoli adds colour and a vegetable side to the meal.
Roasted Green Beans
Green beans provide a slightly crisp contrast to the soft pasta.
Roasted Vegetables
Carrots, courgettes or other seasonal vegetables work well as a simple accompaniment.
These sides are optional suggestions and are not included in the original recipe.
How to Store and Reheat Million Dollar Spaghetti
The original recipe doesn’t provide storage durations or reheating instructions.
For leftovers, allow the casserole to cool briefly, then transfer it to shallow, covered containers and refrigerate promptly.
Reheat portions thoroughly until piping hot throughout.
Because the dish contains spaghetti and a creamy cheese filling, gentle reheating can help prevent the pasta from drying out.
If reheating in the oven, covering the dish is an optional way to help retain moisture.
