How to Make Million Dollar Spaghetti Casserole

Step 1: Preheat the Oven

Preheat your oven to 350 degrees Fahrenheit. Grease either a 9×13 inch baking dish or two 8×8 inch dishes with cooking spray or butter.

Boil the spaghetti noodles according to package instructions. Once cooked, drain them well and toss with a drizzle of olive oil to prevent sticking.

Step 3: Prepare the Cheese Mixture

In a stand mixer, combine softened cream cheese, cottage cheese, and sour cream. Mix until smooth and set aside.

Step 4: Cook the Meat

In a skillet over medium heat, sauté the ground beef with chopped onion until no longer pink. Drain any excess fat. Add this mixture to the jar of marinara sauce; stir well.

Step 5: Layer the Noodles

Place half of the boiled noodles at the bottom of your greased baking pan.

Step 6: Add Cheese Layer

Sprinkle 2/3 cup grated Parmesan cheese evenly over the noodles.

Step 7: Spread Cream Cheese Mixture

Layer over the noodle base with your prepared cream cheese mixture.

Step 8: Top with Remaining Noodles

Add the remaining half of your cooked spaghetti noodles on top of the cream cheese layer.

Step 9: Add Marinara Sauce

Spread the marinara sauce mixed with ground beef evenly over everything in the pan.

Step 10: Bake Initial Time

Bake in your preheated oven for about 30 minutes.

Step 11: Add Shredded Cheese

Sprinkle 2 cups shredded cheese on top after initial baking time. Return to oven for an additional 15 minutes until bubbly and golden brown.

How to Perfect Million Dollar Spaghetti Casserole

To ensure your Million Dollar Spaghetti Casserole turns out perfectly every time, consider these helpful tips.

  • Use quality ingredients: Fresh or homemade marinara sauce elevates the flavor significantly.
  • Don’t overcook noodles: Cook spaghetti until al dente; they will cook further in the oven.
  • Layer properly: Ensure even layers of noodles, cheese, and sauce for balanced flavor in every bite.
  • Let it rest: Allow the casserole to cool slightly before serving; this helps it set and makes slicing easier.
  • Experiment with cheeses: Try mixing different types of cheese for varied flavors—mozzarella, provolone, or cheddar work well.
  • Add veggies: Incorporate sautéed bell peppers or mushrooms into the meat mixture for added nutrition and taste.

Best Side Dishes for Million Dollar Spaghetti Casserole

Pairing sides with your Million Dollar Spaghetti Casserole can elevate your meal. Here are some great options:

  1. Caesar Salad – Crisp romaine lettuce topped with creamy Caesar dressing and parmesan cheese provides a classic touch.
  2. Roasted Vegetables – Seasoned seasonal veggies roasted until tender add color and nutrients to your plate.
  3. Garlic Breadsticks – Soft breadsticks brushed with garlic butter are perfect for dipping into marinara sauce.
  4. Coleslaw – A tangy coleslaw brings a refreshing crunch that complements the richness of the casserole.
  5. Stuffed Mushrooms – These savory bites can be filled with cheese and herbs, making them an ideal appetizer or side.
  6. Caprese Skewers – Fresh mozzarella balls, basil, and cherry tomatoes drizzled with balsamic glaze make a light side dish option.

Common Mistakes to Avoid

When preparing Million Dollar Spaghetti Casserole, it’s easy to make mistakes that can affect the dish’s flavor and texture. Here are some common pitfalls and how to steer clear of them.

  • Skipping the grease: Not greasing your baking dish properly can lead to sticking. Always use a non-stick spray or butter to ensure easy removal.
  • Overcooking noodles: Cooking spaghetti too long makes it mushy in the casserole. Follow package instructions closely and aim for al dente.
  • Ignoring layering: Failing to layer ingredients properly can affect even cooking. Be sure to layer noodles, sauce, and cheese thoughtfully for best results.
  • Not checking seasoning: Neglecting to season your meat mixture can leave your casserole bland. Taste as you go and adjust seasoning accordingly.
  • Using cold ingredients: Starting with cold cream cheese or cottage cheese can lead to lumps in the mixture. Allow them to come to room temperature for easier blending.

Refrigerator Storage

  • Store leftovers in an airtight container.
  • Keep in the refrigerator for up to 3-4 days.

Freezing Million Dollar Spaghetti Casserole

  • Use a freezer-safe container for best results.
  • Can be frozen for up to 3 months before baking.

Reheating Million Dollar Spaghetti Casserole

  • Oven: Preheat oven to 350°F, cover with foil, and heat until warmed through (about 20-30 minutes).
  • Microwave: Place portions in a microwave-safe dish, cover, and heat on high for 2-3 minutes or until hot.
  • Stovetop: Heat in a skillet over medium-low heat, stirring occasionally until warmed through.
