Step 1: Brown the Beef - Start by heating a large skillet over medium heat. Add the ground beef and let it cook until browned. Try to let it sit for a minute before stirring so it develops a deeper flavor. Once cooked, drain any excess grease. Add the butter and let it melt into the beef.
Step 2: Build the Flavor Base - Sprinkle in the French onion soup mix, then pour in the condensed French onion soup, beef broth, Worcestershire sauce, and garlic powder. Stir everything together until well combined. This is where that rich savory aroma starts to come together.
Step 3: Cook the Noodles - Bring the mixture to a gentle boil, then add the egg noodles. Reduce the heat and let it simmer for about 8 to 10 minutes. Stir occasionally so the noodles cook evenly and do not stick. They will soak up most of the liquid and become tender.
Step 4: Add the Cheese and Finish - Lay the slices of provolone cheese across the top of the skillet. Cover with a lid and let it sit for 2 to 3 minutes until the cheese melts into a smooth layer. Sprinkle the crispy fried onions over the top and add parsley if you like. Serve warm and enjoy every bite.
