Ingredients You’ll Need
- 16 ounces spaghetti: A classic choice for this dish, spaghetti holds the sauce beautifully. You can substitute with any pasta shape you prefer.
- ¼ cup chopped fresh parsley or 2 tablespoons dried: Fresh parsley adds a vibrant color and herbal note; dried works in a pinch.
- 1½ cups shredded mozzarella cheese: Choose part-skim mozzarella for a lower-fat option that still melts perfectly.
- ⅓ cup shredded parmesan cheese: Parmesan gives this dish a salty, nutty flavor that complements the mozzarella beautifully.
- 1 pound lean ground beef or Italian sausage: Beef offers a hearty taste, but Italian sausage adds a fragrant herby kick.
- 1 green bell pepper, diced: This veggie brings crunch and a touch of sweetness; feel free to mix in red or yellow peppers for variation.
- 1 small onion, diced: Onions provide a foundational flavor that’s hard to beat in any savory dish.
- 2 cloves garlic, minced: Garlic is a must for that extra depth of flavor; fresh is best but jarred works in a pinch.
- ½ teaspoon salt or to taste: Salt elevates all the flavors, so adjust according to your preferences.
- 32 ounces pasta sauce or marinara sauce: Use your favorite store-bought brand or make it homemade for extra flair.
- 1 (14.5 ounces) can diced tomatoes with juices: These tomatoes add texture and a fresh taste; diced tomatoes with herbs are a nice twist.
- 1½ teaspoons Italian seasoning: This blend of herbs contributes that classic Italian flavor, tying the dish together perfectly.
How to Make Baked Spaghetti
- Preheat the Oven: Set your oven to 375°F (190°C) and grease a 9×13-inch baking dish to ensure nothing sticks.
- Cook the Spaghetti: In a large pot of salted water, cook the 16 ounces of spaghetti al dente according to package directions. This usually takes about 8-10 minutes. Drain and set aside.
- Brown the Meat: In a large skillet over medium-high heat, brown 1 pound of lean ground beef or Italian sausage along with the diced green bell pepper, diced onion, minced garlic, and ½ teaspoon of salt. Break up the meat as it cooks. Drain excess fat if needed to avoid a greasy dish.
- Simmer the Sauce: Stir in the 32 ounces of pasta sauce, 1 can of diced tomatoes (with juices), and 1½ teaspoons of Italian seasoning. Allow the mixture to simmer uncovered for about 5 to 10 minutes or until slightly thickened. Add the cooked spaghetti and chopped parsley, stirring until thoroughly combined.
- Assemble and Bake: Transfer the spaghetti mixture to the prepared baking dish. Top it with 1½ cups of shredded mozzarella cheese and ⅓ cup of shredded parmesan cheese. Bake for 25-30 minutes or until it’s hot, bubbly, and the cheese is golden brown. Let it cool slightly before cutting into squares to serve.
Storing & Reheating
If you find yourself with leftovers, baked spaghetti can be stored at room temperature for a couple of hours, but it’s best to refrigerate if you’re not serving it right away. Transfer to an airtight container for up to 3-4 days in the refrigerator. You can also freeze portions of it for up to 3 months—just make sure it cools completely before wrapping it tightly. To reheat, pop it in a 350°F oven for about 20-25 minutes, adding a splash of water to keep it moist, or microwave individual portions for 2-3 minutes until heated through. The texture might change a bit, but it remains delicious!
Chef’s Helpful Tips
- Avoid Overcooking the Pasta: Cook the spaghetti just shy of tender, since it will continue to cook in the oven.
- Fresh Ingredients Matter: For the best flavor, use fresh garlic and herbs, if possible.
- Brown the Meat Well: Make sure to brown the meat thoroughly for maximum flavor; it should smell amazing as it cooks.
- Customize Your Cheeses: Experiment with different cheese blends for unique flavor profiles. Cheddar or gouda can be delightful additions.
- Prepare Ahead: You can assemble this dish ahead of time and refrigerate it, then bake it fresh before serving.
There you have it! Baked spaghetti is a deliciously simple dish that checks all the boxes—comforting, flavorful, and perfect for feeding a crowd. Don’t hesitate to modify it to suit your tastes or what’s in your pantry. Enjoy the process and the inevitable joy it brings to the table!
