Step 1: Brown the Ground Beef - Start by browning the ground beef in a skillet over medium heat. Break it up as it cooks so the pieces stay small and tender. Once it is fully cooked, drain off any excess grease. This keeps the final dish rich but not oily.
Step 2: Add Beef to the Slow Cooker - Transfer the cooked ground beef to your slow cooker. Spread it out evenly across the bottom so the spices mix in well during the next step.
Step 3: Add the Seasonings - Sprinkle the paprika, onion powder, garlic powder, salt, sugar, and black pepper directly over the beef. Give everything a good stir so the meat is evenly coated with the seasoning mixture.
Step 4: Prepare the Thickening Base - In a small bowl whisk the cornstarch with the hot water until completely smooth. This prevents lumps later and helps the sauce thicken evenly as it cooks.
Step 5: Build the Sauce - Pour the cornstarch mixture and the milk into the slow cooker. Stir everything together so the beef and spices blend into the liquid. This mixture will slowly transform into a creamy savory sauce as it cooks.
Step 6: Slow Cook the Base - Place the lid on the slow cooker and cook on low for about three hours. This slow simmer allows the spices to bloom and the beef flavor to deepen.
Step 7: Add the Pasta - After the base has cooked, stir in the dry elbow macaroni. Make sure the pasta is mostly submerged in the liquid so it cooks evenly.
Step 8: Finish Cooking the Pasta - Cover again and cook for another twenty five to thirty five minutes. The pasta should become tender while soaking up the creamy cheeseburger flavored sauce.
Step 9: Stir in the Cheese - Once the pasta is fully cooked, stir in the shredded sharp cheddar cheese. Mix gently until the cheese melts completely and the sauce becomes smooth and creamy.
Step 10: Let It Rest - Let the dish sit for about five to ten minutes before serving. The sauce naturally thickens during this time and coats the pasta beautifully.
