Ingredients (Serves 6-8)
For the casserole:
- 12 oz spaghetti – The perfect amount for a hearty dish, but feel free to use whole wheat or gluten-free pasta for a twist.
- 1 (8 oz) package cream cheese, softened – Full-fat works best for that luscious texture, but low-fat is a great lighter option.
- 1 ½ cups shredded mozzarella cheese, divided – Mozzarella brings the gooey, stretchy factor we all love.
- ¾ cup grated Parmesan cheese – Adds a nutty, salty kick to the topping.
- ¾ cup sour cream – For a tangy richness that balances the sauce.
- 1 (24 oz) jar marinara sauce – Choose your favorite brand or make your own for a personal touch.
- 1 tsp garlic powder – Infuses the dish with a subtle, savory warmth.
- 1 tsp Italian seasoning – A blend of herbs like oregano and basil to elevate the flavor.
- ¾ tsp kosher salt – Enhances every ingredient.
- ½ tsp freshly ground black pepper – Adds a gentle kick.
- 1 lb ground beef, Italian sausage, or plant-based meat (optional) – For a heartier, protein-packed version.
- 2 tbsp olive oil (if using meat) – To sauté and build flavor.
For garnish (optional):
- Fresh parsley or basil, finely chopped – A pop of color and freshness.
- Red pepper flakes – For those who love a hint of heat.
Equipment Needed
- Large pot for boiling pasta
- Colander
- Large mixing bowl
- Wooden spoon or spatula
- 9×13-inch baking dish (or similar size)
- Nonstick cooking spray or butter for greasing
- Aluminum foil (optional, for covering during baking)
Instructions
- Set the Stage: Preheat and Prep
Begin by preheating your oven to 350°F (175°C). This ensures your casserole bakes evenly, achieving that perfect golden crust. Grease a 9×13-inch baking dish with nonstick spray or a thin layer of butter to prevent sticking and make cleanup a breeze. If you’re using meat, now’s a good time to start cooking it (see step 3). - Cook the Spaghetti to Perfection
Fill a large pot with water, add a generous pinch of salt, and bring it to a rolling boil. Add the 12 oz of spaghetti and cook according to the package instructions until al dente (typically 8-10 minutes). Al dente is key here, as the pasta will continue cooking in the oven, absorbing the creamy sauce without becoming mushy. Once done, drain the spaghetti in a colander and rinse briefly with cool water to stop the cooking process. Set it aside to cool slightly. - Prepare the Meat (Optional)
If you’re adding protein, heat 2 tbsp olive oil in a large skillet over medium heat. Add 1 lb ground beef, Italian sausage, or plant-based meat, breaking it up with a wooden spoon. Cook for 7-10 minutes, stirring occasionally, until fully browned and cooked through. Drain any excess fat, then stir in ½ cup of the marinara sauce to coat the meat with flavor. Remove from heat and set aside. This step adds a savory depth, but the casserole is just as delicious without meat for a vegetarian option. - Whip Up the Creamy Sauce
In a large mixing bowl, combine the 8 oz softened cream cheese and ¾ cup sour cream. Use a whisk or spatula to blend until smooth and lump-free – this is the heart of the casserole’s luxurious texture. Sprinkle in 1 tsp garlic powder, 1 tsp Italian seasoning, ¾ tsp kosher salt, and ½ tsp black pepper. Stir until the seasonings are fully incorporated, creating a fragrant, creamy base that will cling to every strand of spaghetti. For an extra zing, you can add a pinch of onion powder or smoked paprika at this stage. - Build the Flavorful Casserole Base
Pour the 24 oz jar of marinara sauce into the cream cheese mixture, stirring until it transforms into a rosy, velvety sauce. If you’re using the cooked meat, fold it in now for a hearty touch. Add the cooked spaghetti to the bowl, along with ¾ cup of shredded mozzarella cheese. Gently toss everything together, ensuring the pasta is evenly coated in the creamy, saucy goodness. The mozzarella will start to melt slightly, creating pockets of cheesy delight. - Assemble the Casserole
Transfer the spaghetti mixture to the greased baking dish, spreading it out evenly with a spatula. Sprinkle the remaining ¾ cup mozzarella cheese and ¾ cup grated Parmesan cheese over the top, creating a generous cheesy blanket. The mozzarella will melt into gooey perfection, while the Parmesan adds a crispy, golden crust. For an extra touch, you can sprinkle a pinch of Italian seasoning or dried oregano on top for added aroma. - Bake to Bubbly Perfection
Place the casserole in the preheated oven and bake for 25-30 minutes, or until the cheese is melted, bubbly, and lightly golden around the edges. If you prefer a more browned top, you can broil the casserole for 1-2 minutes at the end (watch closely to avoid burning!). If the cheese is browning too quickly during baking, loosely cover the dish with aluminum foil. - Rest and Garnish
Remove the casserole from the oven and let it rest for 5-10 minutes. This allows the flavors to meld and makes serving easier, as the sauce will thicken slightly. For a finishing touch, sprinkle with freshly chopped parsley or basil for a burst of color and freshness. If you like a little spice, offer red pepper flakes on a side for guests to sprinkle on their portions. - Serve and Savor
Scoop generous portions onto plates and serve warm, paired with a crisp green salad, garlic bread, or roasted vegetables for a complete meal. This casserole is a crowd-pleaser, so don’t be surprised if everyone goes back for seconds!
Tips for Success
- Make It Ahead: Assemble the casserole up to a day in advance, cover tightly with plastic wrap or foil, and refrigerate. When ready to bake, let it sit at room temperature for 30 minutes, then bake as directed, adding 5-10 minutes to the baking time if needed.
- Freezer-Friendly: This dish freezes beautifully! Assemble the casserole (without baking), wrap tightly in plastic wrap and foil, and freeze for up to 3 months. Thaw in the refrigerator overnight before baking.
- Customize It: Swap the marinara for Alfredo sauce for a white sauce twist, or add veggies like sautéed mushrooms, spinach, or zucchini for extra nutrition. For a spicy kick, use arrabbiata sauce or add diced jalapeños.
- Cheese Variations: Experiment with cheddar, provolone, or a blend of Italian cheeses for a different flavor profile.
- Gluten-Free Option: Use gluten-free spaghetti and double-check that your marinara sauce and seasonings are gluten-free.
- Portion Control: This recipe serves 6-8, but you can halve the ingredients and use an 8×8-inch dish for a smaller crowd.
