Step‑by‑Step Instructions for Baked Cream Cheese Spaghetti Casserole
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). This is a crucial step to ensure your Baked Cream Cheese Spaghetti Casserole cooks evenly and develops that golden, crispy top layer. While the oven heats up, gather all your ingredients and equipment, including a large pot for boiling the pasta and a 9x13-inch baking dish for assembly.
Step 2: Boil the Spaghetti
In a large pot, bring salted water to a boil, then add your spaghetti. Cook according to the package instructions until al dente, typically about 8-10 minutes. After draining the pasta, ensure it's well-drained to avoid excess moisture in your casserole. This step is vital for achieving the right texture in your dish.
Step 3: Prepare the Creamy Mixture
In a mixing bowl, combine the softened cream cheese, sour cream, and optional mayonnaise. Beat these ingredients together with a hand mixer or spatula until the mixture is smooth and creamy. This fluffy consistency will help create the deliciously rich sauce that binds the Baked Cream Cheese Spaghetti Casserole together.
Step 4: Add Flavorings and Eggs
Once your creamy base is smooth, stir in the eggs, garlic powder, and onion powder until everything is well incorporated. This mixture acts as the flavorful foundation of your casserole. Make sure to mix thoroughly to ensure the eggs are evenly distributed, giving your dish a wholesome taste.
Step 5: Combine Everything Together
Add the drained spaghetti to the creamy mixture along with half of the cheddar cheese. Gently fold the ingredients until all the pasta is coated in that luscious sauce. This step brings together the comforting elements of the Baked Cream Cheese Spaghetti Casserole, ensuring every bite is deliciously creamy.
Step 6: Assemble the Casserole
Grease your baking dish with cooking spray or butter, then pour the spaghetti mixture into the dish, spreading it evenly. Sprinkle the remaining cheddar cheese generously over the top; this will melt beautifully and create a wonderfully crispy layer as it bakes, making your casserole irresistibly appealing.
Step 7: Bake to Perfection
Place the baking dish in your preheated oven and bake for 30-40 minutes. Keep an eye on it, and look for the top to become bubbly and golden brown. This visual cue indicates that your Baked Cream Cheese Spaghetti Casserole is perfectly cooked and ready to deliver that comforting goodness.
Step 8: Cool and Serve
After removing the casserole from the oven, let it cool for about 10 minutes before serving. This resting period allows the sauces to settle and makes it easier to cut into portions. Now you can serve up this warm, creamy dish that is sure to delight family and friends alike!
