How to Make Baked Spaghetti
- Preheat and Prepare: Preheat your oven to 375°F. Grease a 9×13-inch baking dish to prevent sticking.
- Cook the Spaghetti: In a large pot of salted boiling water, cook the spaghetti al dente according to package directions. You want it to have a little bite since it will continue to cook in the oven.
- Cook the Meat and Vegetables: In a large skillet over medium-high heat, brown the ground beef or Italian sausage. Add the diced green bell pepper, onion, garlic, and salt. Cook until the meat is browned and vegetables are tender, breaking up the meat as it cooks. Drain any excess fat if needed.
- Combine Sauce and Spaghetti: Stir in the pasta sauce, diced tomatoes, and Italian seasoning into the skillet. Allow it to simmer uncovered for about 5 to 10 minutes like a gentle lullaby for the flavors to meld. Stir in the cooked spaghetti and chopped parsley until well combined.
- Assemble and Bake: Transfer the mixture into the prepared baking dish. Top it with shredded mozzarella and parmesan cheese. Bake in the preheated oven for 25-30 minutes or until the cheeses are bubbling and golden. Let it sit for a few minutes before cutting into squares to serve—this will make serving easier!
Storing & Reheating
To store, keep any leftovers in an airtight container at room temperature for up to 2 hours, and then transfer to the refrigerator where it will last for about 3-5 days. For longer storage, freeze in an airtight container for up to 3 months. Reheat in a preheated oven at 350°F for about 20 minutes or until hot throughout. You may notice a change in texture; adding a splash of marinara sauce before reheating can help refresh it.
Chef’s Helpful Tips
- To avoid dry pasta, cook it just until al dente, as it will finish cooking while baking.
- For a creamier texture, consider stirring in a bit of ricotta cheese before baking.
- Letting the baked spaghetti rest after coming out of the oven helps it set up, making it easier to serve.
- Experiment with different cheeses on top—pepper jack can add a fun kick!
- If preparing in advance, assemble but don’t bake until ready to serve, keeping the cheese topping fresh and delicious.
The beauty of baked spaghetti lies in its versatility. You can make it exactly how you want it, whether it’s spicy, cheesy, or loaded with veggies. It’s such a satisfying meal that’s easy to adapt. I encourage you to try it out and play around with ingredients until you find your perfect mix. Enjoy each comforting bite!
