Tips
Don't skip the foil cover during the first bake phase; it keeps noodles from drying out and ensures even heating of all ingredients.
Watch fried onions closely during the final bake; they brown quickly and can burn in seconds once uncovered.
Good to Know
Cover and refrigerate up to 3 days. Reheat covered at 350°F until warmed through.
Assemble through step 5 up to 24 hours ahead. Refrigerate covered. Add 5-10 minutes to bake time if starting from cold.
Serve directly from baking dish. Pairs with a simple green salad or steamed broccoli.
Common Mistakes
Skip mixing before baking to avoid dry patches and uneven seasoning.
Add fried onions at the start to avoid soggy, limp topping.

FAQ
Can I use fresh cooked beef instead of the refrigerated package?
Yes. Use 17 ounces cooked shredded or cubed beef and replace the gravy by mixing 1 cup beef broth with 2 tablespoons cornstarch, heated until thickened.
What if I don't have french-fried onions?
Crush 2/3 cup panko breadcrumbs, toss with 3 tablespoons melted butter and pinch of salt, then sprinkle and bake. Or use crushed fried shallots or chow mein noodles.
Can I make this ahead and freeze?
Yes, freeze unbaked through step 5 up to 2 months. Thaw overnight in refrigerator, then bake adding 10-15 minutes. Add onions only after thawing before baking.
