Ingredients Notes
The beauty of this recipe is its adaptability to what you have on hand. Use fresh tomatoes if you can, but canned work just as well. Mozzarella is the classic choice for cheesiness, but Swiss or provolone can offer a unique twist. For a richer taste, include a mix of beef and pork. Spice things up by adding a dash of chili flakes.
Recipe Steps
Step 1
Start by preheating your oven to 350°F (175°C). Cook the spaghetti according to package instructions, and drain well.
Step 2
In a large skillet over medium heat, cook the ground beef until browned. Drain excess fat and stir in diced tomatoes and tomato sauce.
Step 3
Add cooked spaghetti to the skillet and mix well with the meat sauce. Adjust seasoning with salt, pepper, and herbs to taste.
Step 4
Transfer half of the spaghetti and sauce mixture to a greased baking dish. Sprinkle with half of the shredded cheese. Repeat the layers.
Step 5
Bake uncovered for 20 minutes, or until the top is golden and bubbly. Let it cool for a few minutes before serving.
Storage Options
If you have leftovers, store them in an airtight container in the fridge for up to 3 days. To freeze, wrap the casserole tightly in plastic wrap and aluminum foil. It can be frozen for up to 2 months. Thaw overnight in the fridge and reheat in the oven until warm throughout.
Variations & Substitutions
For a vegetarian version, substitute the ground beef with sautéed mushrooms and bell peppers. Gluten-free pasta can be used to cater to dietary restrictions. For a spicy kick, consider adding chorizo sausage or jalapeños into the mix.
