This oven baked 5-ingredient spaghetti is the kind of budget dinner that earns a permanent spot in the weeknight rotation. It turns a few basic pantry and freezer staples into a hot, filling casserole that feeds a crowd, and it reminds me of the big baked pasta dinners that showed up when money was tight but everyone still needed a full plate. The noodles soak up the sauce, the cheese browns on top, and the whole dish slices and serves easily, which makes it especially handy on busy nights.
Serve this baked spaghetti with garlic bread, buttered toast, or a simple green salad if you want to stretch it even further. Since the pasta is rich, something crisp and fresh on the side works well, but honestly this is also the kind of meal that can stand on its own when you just need an easy, hearty supper on the table fast.
Oven Baked 5-Ingredient Spaghetti Rowland
Servings: 8
Ingredients
1 pound spaghetti
1 pound ground beef
24 ounces pasta sauce
2 cups shredded mozzarella cheese
1 teaspoon garlic powder
Directions
1. Preheat the oven to 375°F and lightly grease a 9x13-inch baking dish.
2. Bring a large pot of salted water to a boil and cook the spaghetti until just tender, then drain.
3. While the pasta cooks, brown the ground beef in a large skillet over medium heat, breaking it up as it cooks. Drain any excess grease.
4. Stir the pasta sauce and garlic powder into the cooked beef and simmer for 2 to 3 minutes.
5. Add the drained spaghetti to the skillet or a large bowl and toss with the sauce mixture until evenly coated.
6. Spread half of the spaghetti mixture into the prepared baking dish, sprinkle with 1 cup of mozzarella, then add the remaining spaghetti and top with the rest of the cheese.
7. Bake uncovered for 20 to 25 minutes, until hot and bubbly and the cheese is melted and lightly golden. Let stand for 10 minutes before slicing and serving.
Variations & Tips
Make it extra filling: If you need to stretch dinner even more, add a second half-pound of cooked ground beef if your budget allows, or mix in a little extra sauce so every serving stays generous and moist.
Cheese swap: Mozzarella gives that classic stretchy top, but an Italian blend or a little cheddar mixed in works well too. Use whatever shredded cheese you already have in the fridge for a practical clean-out meal.
Freezer tip: Assemble the casserole ahead of time, cover tightly, and freeze before baking. When life gets hectic, having a budget-friendly pasta bake ready to pull out is a lifesaver on a work night.
Prevent dry spaghetti: Slightly undercook the noodles and make sure they are well coated in sauce before baking. That small step helps the pasta stay tender instead of soaking up too much moisture in the oven.
Add-ins if you have them: This recipe stays true to the five-ingredient idea, but if you need to use up extras, a little diced onion, Italian seasoning, or a spoonful of grated Parmesan can add flavor without changing the easy feel of the dish.
