Creating this dish is a straightforward process that even my daughters can follow, as they eagerly help stir and taste. Here’s how you can bring this comforting meal to life:

1. In a large skillet, heat the olive oil over medium heat. Add the chopped onion, letting it sizzle and soften, much like the way my grandmother would start her marinara sauce.
2. Add the minced garlic, stirring until fragrant. This aroma always transports me back to my childhood kitchen.
3. Increase the heat slightly and add the ground beef. Cook until browned, breaking it apart with a wooden spoon—a technique my mother taught me as I watched from my flour-covered stool.
4. Sprinkle in the paprika and Italian seasoning, stirring to coat the beef evenly. These spices carry the warmth of family dinners and the essence of my culinary travels.
5. Pour in the beef broth and milk, bringing the mixture to a gentle simmer. Stir in the pasta shells, reminiscent of the meals we enjoyed after long days by the sea.
6. Cover and cook for about 12-15 minutes, until the pasta is tender and the liquid has thickened into a luscious sauce.
7. Stir in the shredded cheddar cheese, allowing it to melt and envelop the pasta in a creamy embrace.
8. Season with salt and pepper to taste, adjusting as needed to recreate the flavors of home.
