Step‑by‑Step Instructions for Slow Cooker Creamy Ground Beef and Shells

Step 1: Cook Ground Beef
In a medium skillet set over medium-high heat, add the lean ground beef and cook for about 5-7 minutes. Use a wooden spoon to break it up as it browns, ensuring it cooks evenly until there’s no pink remaining. Once done, drain any excess fat and transfer the cooked beef into the slow cooker.

Step 2: Combine Ingredients
With the ground beef in the slow cooker, add the cream of mushroom soup, shredded cheddar cheese, uncooked shell pasta, milk, onion powder, kosher salt, and freshly ground black pepper. Stir everything together thoroughly, ensuring the cheese and pasta are evenly coated in the creamy mixture for your Slow Cooker Creamy Ground Beef and Shells.

Step 3: Cook the Casserole
Place the lid on the slow cooker and set it to cook on high for approximately 3.5 hours. During the last half-hour, give it a gentle stir to prevent the pasta from sticking and check the pasta’s doneness. The edges should bubble, and the pasta should be tender but not mushy.

Step 4: Serve and Garnish
Once cooked, carefully ladle the Slow Cooker Creamy Ground Beef and Shells into bowls. For an appealing presentation, consider garnishing with fresh chopped parsley or a dollop of sour cream. Serve hot, allowing the rich, creamy flavors to delight your family and friends during mealtime.
