Creamy Baked Spaghetti Casserole

The secret sauce—and I mean that literally—is the creamy layer of cheesy goodness mixed right into the noodles. It’s what gives this recipe that famous rich taste. We take simple cooked spaghetti and toss it with the soft, decadent cheese and seasonings, creating a gorgeous, creamy core before we even add the meat sauce. It adds a richness and comforting quality you just don’t get with regular baked pasta dishes.

Look, this is a lifesaver because the active cooking time is minimal. You can multitask while the meat browns and the pasta boils, and then assembly is a breeze: layer, bake for about half an hour, and done. This hearty casserole easily feeds my whole tribe of hungry boys (plus their friends!), freezes beautifully for next time (hallelujah!), and is guaranteed to be scraped clean. It’s truly comfort food at its easiest and cheesiest!

Ingredients You’ll Need

• The long, thin pasta base that forms the bulk of the casserole.
• The affordable ground protein that gives the savory sauce its necessary heft.
• The canned tomato product that forms the main liquid base of the sauce.
• The soft, tangy dairy product that blends with the hot pasta to create a creamy core.
• A blend of dried aromatic herbs that elevates the overall flavor of the dish.
• The primary savory spices used to punch up the flavor of the beef and the pasta base.
• Aromatic fresh or jarred cloves that enhance the richness of the cheese layer.
• A salty, hard grating cheese that is sprinkled over the sauce for sharp flavor before baking.
• The classic white shreddable cheese that melts beautifully on top to form the golden crust.

How It’s Made

This hearty dish is built in two main parts: first, the pasta is cooked and immediately combined with the soft, creamy cheese and seasonings to form a rich center layer. Simultaneously, the ground beef is browned and stirred directly into the tomato sauce. The final steps involve layering these components—a light layer of meat sauce, the creamy noodles, and the remaining sauce—in a baking dish. The entire dish is topped with shredded cheese and baked until it’s golden, bubbly, and heated through completely.

Tips, Variations & Storage

• Tip for Creaminess: Ensure your main soft cheese is completely at room temperature; this allows it to melt smoothly and evenly into the hot pasta instead of clumping.
• Substitution: Instead of traditional ground beef, swap in Italian sausage (sweet or hot) for a huge boost of fennel and spice flavor.
• Add-in: For a hidden veggie boost, sauté a handful of diced onion or chopped bell pepper along with the ground beef until soft.
• Dietary Swap: Easily make this gluten-free by swapping the traditional spaghetti for your favorite gluten-free pasta noodles.
• Storage: Store any leftover portions in an airtight container in the refrigerator for up to 3 days.
• Freezer Notes: Assemble the entire casserole (up to the point of baking), cover it tightly, and freeze for 3-4 months. Thaw overnight in the fridge and then bake as directed.

FAQ

Do I need to fully cook the spaghetti before baking? No, you only need to cook the pasta until it is al dente (slightly underdone). It will continue to cook and absorb the sauce during the 35 minutes in the hot oven.

Can I use a different type of cheese in the noodle layer? Absolutely! While the soft cream cheese is traditional, you could try substituting it with Ricotta cheese for a slightly different, more lasagna-like texture and flavor.

Why is it important to drain the grease from the meat? Draining the excess grease prevents the final casserole from being overly oily and heavy. The sauce should only be coated in the meat, not swimming in pooled fat.

What should I serve with this casserole? This meal is very rich on its own, so a light side like a crisp Caesar salad or a simple, steamed green vegetable like broccoli or green beans is the perfect accompaniment.

Will the leftovers dry out when reheated? Sometimes, baked pasta can absorb liquid when stored. To prevent it from drying out, cover the dish with foil and add a splash of water or broth before popping it in the oven or microwave to reheat.

Recipes

• 1 lb. Dry spaghetti noodles
• 1 lb. Lean ground beef
• 28 oz. Jar of prepared tomato pasta sauce
• 8 oz. Package of cream cheese fully softened to room temperature
• 1 tsp. Minced garlic from a jar or fresh
• ¼ tsp. Granulated garlic salt
• 1 tsp. Dried Italian seasoning blend
• ½ cup Grated Parmesan cheese
• ½ cup Shredded mozzarella cheese

Instructions

• Prep the Pasta: Bring a large pot of water to a vigorous boil. Add the spaghetti and cook only until the noodles are al dente (slightly firm to the bite). Immediately drain the pasta well and set it aside.
• Preheat and Prepare: Adjust your oven rack and preheat the oven temperature to 350°F. Lightly grease the interior of a standard 9×13 inch baking dish.
• Brown the Meat: In a large skillet, cook the ground beef over medium-high heat, breaking it up as it cooks, until it is entirely browned. Drain off any accumulated grease.
• Finish the Sauce: Reduce the heat under the skillet. Pour in the entire jar of pasta sauce and stir it into the cooked ground beef until fully incorporated. Remove from heat and set the meat sauce aside.
• Create the Creamy Base: Transfer the hot, drained spaghetti to a very large mixing bowl. Add the softened cream cheese, minced garlic, garlic salt, and Italian seasoning. Stir the mixture vigorously until the heat from the pasta melts the cream cheese, coating the noodles completely and evenly.
• Layer the Casserole: Spread a generous portion of the prepared meat sauce across the bottom of the greased 9×13 inch baking dish.
• Add the Noodle Layer: Carefully spoon the creamy, seasoned spaghetti mixture on top of the sauce layer. Spread it gently to form an even second layer.
• Top with Remaining Sauce: Pour the remaining meat sauce evenly over the spaghetti layer.
• Sprinkle the Cheeses: Sprinkle the grated Parmesan cheese evenly over the sauce, followed by the shredded mozzarella cheese.
• Bake: Place the casserole dish into the preheated oven and bake, uncovered, for 35 minutes, or until the sauce is bubbly and the top is melted and lightly golden. Allow it to rest for a few minutes before cutting and serving.
