Step-by-Step Guide to Preparing the Spaghetti Bake Casserole

Alright, now that we’ve got everything we need, let’s get cooking! Follow these steps, and you’ll have a Spaghetti Bake Casserole that’s ready to impress.

1. Preheat Your Oven

First things first, preheat your oven to 350° Fahrenheit. This will ensure that it’s hot and ready by the time you’ve assembled your casserole.

2. Cook the Spaghetti

• Fill a large pot with water, add a generous pinch of salt, and bring it to a boil.
• Once the water is boiling, add your 16 ounces of spaghetti. Cook the pasta 1 minute shy of al dente—this is important because the pasta will continue to cook when it’s baked in the casserole, and you don’t want it to get too soft.
• Once cooked, drain the spaghetti in a colander, then toss it with 1/4 cup of butter to keep it from sticking together. Set it aside for later.

3. Brown the Meat

• While your pasta is cooking, grab a large skillet or Dutch oven and place it over medium heat.
• Add 1 pound of ground beef and 1 pound of Italian sausage to the skillet. Use a wooden spoon or spatula to break up the meat as it cooks.
• As the meat begins to brown, toss in 1 diced onion. Continue cooking until the meat is fully browned and the onion is soft.
• Drain any excess fat from the skillet to keep your casserole from being too greasy.
• Return the skillet to the heat, and add 28 ounces of crushed tomatoes, 15 ounces of tomato sauce, 3 tablespoons of Italian seasoning, 1 teaspoon of minced garlic, 1 teaspoon of salt, and 1 teaspoon of fresh black pepper.
• Let the sauce simmer on low heat for about 5 minutes. This gives all those flavors time to meld together into something truly delicious.

4. Prepare the Ultimate Cheese Layer

• While your meat sauce is simmering, it’s time to get the cheese layer ready. This is what takes this casserole from good to “oh my goodness, I need another bite”!
• In a medium bowl, combine 8 ounces of cream cheese (make sure it’s at room temperature so it mixes easily), 8 ounces of cottage cheese, 8 ounces of sour cream, 1 cup of shredded Parmesan cheese, 2 teaspoons of dried parsley, and 1/2 teaspoon of salt.
• Mix everything together until it’s smooth and creamy.

5. Assemble the Casserole

• Now comes the fun part—putting it all together!
• Spray a large casserole dish with non-stick cooking spray.
• Start by spreading a thin layer of your meat sauce in the bottom of the dish. This helps keep the pasta from sticking and adds flavor to every bite.

Layer 1:

• Add half of your cooked spaghetti to the bottom of the dish. Use a fork or tongs to spread it out evenly.

Layer 2:

• Next, spread the entire cheese mixture over the noodles. This creamy layer is what makes this casserole so special.

Layer 3:

• Add the rest of your spaghetti on top of the cheese layer, again making sure it’s evenly distributed.

Layer 4:

• Pour the remaining meat sauce over the top of the noodles, spreading it out so every bit of pasta is covered.

Layer 5:

• Finally, top the casserole with 2 1/2 cups of shredded mozzarella cheese. Sprinkle 1-2 teaspoons of dried parsley over the cheese for a bit of extra flavor and a pop of color.

6. Bake the Casserole

• Place your assembled casserole in the preheated oven and bake for 35-45 minutes. You’ll know it’s ready when the cheese is melted, bubbly, and starting to turn golden brown.
• Once it’s done, take it out of the oven and let it cool for a few minutes before serving. This will help the casserole set, making it easier to slice and serve.

7. Serve and Enjoy

• Now comes the best part—digging in! This Spaghetti Bake Casserole is best enjoyed hot and fresh out of the oven. Serve it up with a side salad, some garlic bread, or whatever you like.

Expert Tips and Tricks

• Don’t Overcook the Pasta: Remember, the pasta will continue to cook in the oven, so be sure to undercook it slightly when boiling. This will prevent it from becoming too soft and mushy.
• Use Fresh Ingredients: Whenever possible, use fresh garlic, parsley, and other herbs. They add a brightness and depth of flavor that dried herbs just can’t match.
• Make It Ahead: This casserole is a great make-ahead dish. You can assemble it the day before, cover it tightly with plastic wrap, and refrigerate it until you’re ready to bake. Just add an extra 10-15 minutes to the baking time if it’s coming straight out of the fridge.
• Add Veggies: Want to sneak in some extra nutrition? Add chopped veggies like bell peppers, spinach, or mushrooms to the meat sauce. They’ll blend right in and add some extra flavor and texture.
• Use a Mix of Cheeses: While mozzarella is a classic choice, don’t be afraid to mix it up with other cheeses like cheddar, provolone, or even a bit of smoked gouda for a different flavor profile.
• Let It Rest: After baking, let the casserole rest for about 10 minutes before cutting into it. This helps the layers set and makes it easier to serve neat slices.
• Spice It Up: If you like a bit of heat, add some crushed red pepper flakes to the meat sauce or sprinkle some over the top before baking.
