How to Make Million Dollar Spaghetti Casserole
Step 1: Preheat the Oven
Preheat your oven to 350 degrees Fahrenheit. Grease a 9×13 inch baking dish or two 8×8 inch dishes with cooking spray or olive oil.
Step 2: Cook the Spaghetti Noodles
Boil your spaghetti noodles according to package instructions. Once cooked, drain the noodles in a colander. To prevent sticking, drizzle with a little olive oil and toss gently.
Step 3: Prepare the Cheese Mixture
In your stand mixer (or a mixing bowl), combine cream cheese, cottage cheese, and sour cream. Mix until well blended and smooth. Set aside for later use.
Step 4: Cook the Ground Beef and Onion
In a skillet over medium heat, sauté the ground beef and chopped onion. Cook until the meat is no longer pink. Drain any excess fat before adding this mixture to your jar of marinara sauce. Stir well to combine.
Step 5: Layer the Ingredients
Start by layering half of your cooked spaghetti noodles on the bottom of your greased baking pan. Follow this with a garnish of 2/3 cup grated Parmesan cheese. Spread out the cream cheese mixture evenly over this layer.
Step 6: Finish Layering
Top with the remaining spaghetti noodles before spreading the marinara sauce mixed with ground beef over everything.
Step 7: Bake
Place your casserole in the preheated oven. Bake for about 30 minutes. After this time, sprinkle with 2 cups shredded cheese. Return to the oven for an additional 15 minutes until bubbly and golden brown.
Step 8: Serve
Once baked, let it cool for about 15 minutes before slicing into squares to serve warm. Enjoy your delicious Million Dollar Spaghetti Casserole!
