Baked Penne with Sausage and Mozzarella

Preheat your oven to a high temperature of 350 degrees Fahrenheit (or 175 degrees Celsius, if you prefer metric).

Next, fill a large pot with salted water and put it on the stovetop to boil. Add penne pasta and cook, stirring occasionally, until it reaches your desired level of doneness - still slightly firm but not hard to bite into. This should take around 11 minutes, after which you can drain the water.

In a large and deep skillet, heat some oil over medium-high heat. Add sliced sausage and chopped onion to the pan and cook until everything is evenly browned. Remove any excess fat from the skillet.

Now, pour a glass of wine into the pan and bring it to a boil. Use a wooden spoon to scrape up any browned bits of food that are stuck to the bottom of the pan.

Mix in a store-bought or homemade tomato sauce, diced tomatoes, and paste made from crushed tomatoes. Let the mixture simmer for 10 minutes, stirring occasionally to prevent it from sticking to the bottom of the pan.

Add your cooked penne pasta to the skillet and toss it with the tomato sauce mixture. Transfer the pasta mixture to a 9x13-inch baking dish.

Finally, sprinkle shredded mozzarella cheese over the top of the pasta mixture and place it in a preheated oven. Let it bake for 20 minutes, or until the cheese is melted and bubbly.

Serve your pasta hot, straight from the oven, and enjoy!
