Essential Ingredients for Your Million Dollar Spaghetti Bake

Creating this spectacular Million Dollar Spaghetti requires a selection of fresh, high-quality ingredients that come together to form layers of unparalleled flavor. Each component plays a crucial role in building the dish’s signature taste and texture.

• Uncooked Spaghetti: The foundation of our casserole. Choose a good quality spaghetti that will hold up well during baking without becoming mushy.
• Ground Beef: For a perfect balance of flavor and texture, use either 90/10 or 80/20 lean ground beef. Draining excess fat is key for a non-greasy sauce.
• Mild Italian Sausage: This adds a fantastic depth of flavor and a subtle hint of spice. You can use bulk sausage or remove the casings from links. For a spicier kick, opt for hot Italian sausage.
• Yellow Onion: Finely chopped, it provides a sweet and aromatic base for the meat sauce.
• Green Bell Pepper: Diced, it adds a touch of freshness and a subtle peppery flavor that complements the richness of the meat.
• Mushrooms: Quartered, these earthy morsels add umami and a wonderful texture to the savory meat sauce. Feel free to use cremini or white button mushrooms.
• Garlic Cloves: Freshly chopped garlic is non-negotiable for that authentic Italian aroma and flavor.
• Marinara Sauce: A high-quality jarred or canned marinara sauce works perfectly here, saving time without sacrificing flavor. Look for one with good tomato flavor and minimal added sugar.
• Italian Seasoning: This blend of herbs (typically oregano, basil, thyme, rosemary, and marjoram) ties all the savory elements together beautifully.
• Cream Cheese: Softened to room temperature, it’s the secret to the creamy, tangy middle layer that truly sets this spaghetti bake apart.
• Ricotta Cheese: Whole fat ricotta is highly recommended for its rich, creamy texture and mild, slightly sweet flavor. It contributes significantly to the decadent cheese layer.
• Parmesan Cheese: Freshly grated Parmesan adds a sharp, salty, and nutty flavor to the cheese mixture, enhancing its overall complexity.
• Mozzarella Cheese: Shredded mozzarella is essential for that classic gooey, melty top layer that everyone loves.

Mastering Million Dollar Spaghetti: A Step-by-Step Guide

Creating this impressive baked spaghetti casserole is an enjoyable and straightforward process. Follow these detailed steps to assemble your Million Dollar Spaghetti and delight your family and friends.

1. Prepare Your Workspace and Pasta: Begin by preheating your oven to 375°F (190°C). While the oven heats, lightly grease a 9×13-inch baking dish with cooking spray to prevent sticking and ensure easy cleanup. Next, cook the spaghetti according to the package instructions, aiming for an al dente texture. This is crucial because the pasta will continue to cook in the oven, and al dente spaghetti prevents it from becoming overly soft or mushy. Once cooked, drain the pasta thoroughly and return it to the large pot or transfer it to a spacious mixing bowl.
2. Craft the Rich Meat Sauce: While your spaghetti is cooking, get started on the robust meat sauce. In a large skillet, over medium-high heat, brown the ground beef and Italian sausage together. Break up the meat with a spoon as it cooks. Once the meat is fully browned, drain any excess fat to ensure a lean, flavorful sauce. This step is important for the overall texture and richness of the dish.
3. Sauté the Aromatics and Vegetables: To the browned meat in the skillet, add the chopped yellow onion, quartered mushrooms, diced green bell pepper, and minced garlic. Continue to cook, stirring occasionally, until the onion softens and becomes translucent, and the vegetables are tender-crisp. This infuses the meat mixture with aromatic flavors and adds a welcome texture.
4. Simmer the Sauce to Perfection: Stir in 3 1/2 cups of your chosen marinara sauce to the meat and vegetable mixture. Sprinkle in the Italian seasoning. Bring the sauce to a gentle simmer, then reduce the heat and let it cook for a few minutes, allowing the flavors to meld beautifully. This creates a deeply savory and fragrant base for the casserole.
5. Combine Pasta and Marinara: Take the remaining marinara sauce (about 1/2 cup) and add it to the cooked spaghetti. Toss well to ensure every strand of pasta is lightly coated. This step adds moisture and flavor directly to the pasta layer, preventing it from drying out during baking.
6. Assemble the First Layer: Transfer all the sauced spaghetti into the prepared 9×13-inch baking dish. Spread it out evenly across the bottom to form a uniform base.
7. Prepare the Creamy Cheese Layer: In a small bowl, combine the softened cream cheese, whole fat ricotta cheese, and grated Parmesan cheese. Stir them together until thoroughly mixed and smooth. This creates the signature creamy, tangy, and rich middle layer of the Million Dollar Spaghetti.
8. Apply the Cheese Layer: Using an offset spatula or the back of a spoon, carefully spread the cream cheese mixture evenly over the layer of spaghetti in the baking dish. Be gentle to avoid disturbing the pasta too much.
9. Add the Hearty Meat Sauce Layer: Spoon the prepared meat sauce over the cream cheese layer, spreading it out evenly to cover the entire surface. This ensures a delightful balance of flavors in every bite.
10. Crown with Mozzarella and Bake: Finally, generously sprinkle the shredded mozzarella cheese over the top of the meat sauce. Cover the baking dish tightly with aluminum foil. Bake for approximately 40-45 minutes, or until the casserole is hot and bubbly throughout. For the last 10 minutes of baking, remove the foil to allow the mozzarella cheese to turn golden brown and slightly crispy, creating a beautiful crust.
11. Rest and Serve: Once out of the oven, let the Million Dollar Spaghetti rest for 5-10 minutes before slicing and serving. This allows the layers to set, making it easier to serve and preventing it from falling apart. Enjoy this incredibly satisfying and flavorful dish!

Chef Jenn’s Pro Tips for the Best Million Dollar Spaghetti

Elevate your Million Dollar Spaghetti experience with these expert tips, ensuring a perfect and customized dish every time:

• Spice It Up: If you enjoy a bit of heat, don’t hesitate to substitute mild Italian sausage with hot Italian sausage. You could also add a pinch of red pepper flakes to the meat sauce for an extra kick that awakens the palate.
• Make Ahead Magic: This casserole is an excellent candidate for meal prep. Assemble the entire dish a day in advance, cover it tightly, and store it in the refrigerator. When you’re ready to bake, simply pop it into the preheated oven. Just remember to add an additional 5-10 minutes to the baking time to account for the casserole being fridge-cold.
• Perfect Pasta Texture: Always cook your spaghetti to al dente. This means it should be firm to the bite. Since the spaghetti will continue to cook and absorb flavors in the oven, starting with al dente pasta ensures it doesn’t become mushy or overcooked during the baking process.
• Fresh Herb Finish: A sprinkle of fresh basil or parsley, finely chopped, over the Million Dollar Spaghetti just before serving can make a world of difference. The vibrant freshness of the herbs brightens the rich flavors of the casserole and adds an appealing pop of color.
• Vegetable Boost: Feel free to sneak in more vegetables. Sautéed spinach, finely diced zucchini, or even shredded carrots can be added to the meat sauce for added nutrients and flavor without compromising the dish’s integrity.
• Enhance the Sauce: For a deeper, more complex flavor in your marinara sauce, consider deglazing the pan after browning the meat with a splash of dry red wine before adding the marinara. Let it simmer until the wine reduces slightly.
• Cheese Variations: While the recipe calls for a specific cheese blend, don’t shy away from experimenting. A touch of provolone or fontina can be added to the mozzarella layer for different melting qualities and nuanced flavors.

Transform your Million Dollar Spaghetti from a delicious main course into an unforgettable feast with these thoughtful side dish suggestions.

• Simple Green Salad with Vinaigrette: A light, crisp green salad provides a refreshing contrast to the hearty spaghetti. Use mixed greens, a few cherry tomatoes, and a simple balsamic vinaigrette or lemon-herb dressing. The acidity of the dressing helps cut through the richness of the cheese and meat.
• Roasted Vegetables: For a healthier and equally flavorful side, consider roasting seasonal vegetables like asparagus, broccoli, or Brussels sprouts. A drizzle of olive oil, salt, and pepper is all they need to become tender and slightly caramelized, adding a lovely earthy element to your meal.

Storage Solutions: Keep Your Million Dollar Spaghetti Delicious

One of the many advantages of Million Dollar Spaghetti is how wonderfully it stores, making it perfect for leftovers or strategic meal planning. Here’s how to properly store your culinary creation to maintain its incredible flavor and texture:

• Refrigeration (Baked): If you have leftover baked Million Dollar Spaghetti, ensure it cools completely before transferring it to an airtight container. Stored in the refrigerator, it will remain fresh and delicious for up to 5 days. To reheat, simply microwave individual portions or place a larger portion back in the oven until heated through. Adding a splash of water or extra marinara sauce can help keep it moist.
• Freezing (Unbaked): For ultimate convenience, you can assemble the entire casserole (up to the point of baking) and freeze it before cooking. Wrap the unbaked dish tightly with several layers of plastic wrap, followed by aluminum foil. Label with the date. It will keep well in the freezer for up to 2 months. When you’re ready to bake, transfer the frozen casserole to the refrigerator overnight to thaw. Then, bake as directed, potentially adding an extra 10-15 minutes to the covered baking time since it will be colder than a freshly assembled dish.
• Freezing (Baked Leftovers): Cooked leftovers can also be frozen! Allow the spaghetti to cool completely, then portion it into individual freezer-safe containers or freezer bags. This makes for quick and easy single-serving meals. Freeze for up to 1 month. Thaw in the refrigerator overnight and reheat thoroughly.

With these storage tips, you can enjoy the comforting taste of Million Dollar Spaghetti long after it’s initially prepared, whether it’s a planned make-ahead meal or a delightful unexpected leftover.
