Expert Tips for Perfect Caramelized Onions and Beef

Great French onion flavor starts with deeply caramelizing your onions. To save time and effort, use the Mueller Pro-Series 10-in-1, 8 Blade Vegetable Chopper for quickly slicing your onions uniformly. Brown ground beef evenly using a Farberware Professional Heat Resistant Nylon Meat and Potato Masher—this ensures an even consistency in every casserole bite.

Cooking the onions low and slow in a quality nonstick skillet like the SENSARTE Nonstick Frying Pan Skillet, 9.5 Inch will yield the sweetest results without sticking, and makes cleanup a breeze.

Assembling Your French Onion Beef Casserole Dinner

After caramelizing your onions and browning the beef, toss everything together with beef broth, sour cream, and seasonings. Pour the mixture into your favorite casserole dish, top generously with shredded cheese, and scatter crispy fried onions or toasted bread crumbs on top.

To prevent sticking and for effortless release, line your baking dish with Reynolds Kitchens Brown Parchment Paper Roll, 45 Square Feet before adding your beef-and-onion mixture.
