Equipment

  • 9x13 inch casserole dish
  • Large deep skillet for browning the beef and onions
  • Large pot for boiling the noodles
  • Colander
  • Large mixing bowl
  • Cheese grater if shredding your own cheese
  • Measuring cups and spoons
  • Wooden spoon or spatula

Ingredients
  

  • 1 pound lean ground beef 450g, 80/20 blend
  • 1 tablespoon olive oil
  • 1 medium yellow onion about 1 cup or 150g, diced
  • 2 cloves garlic minced
  • 12 ounces wide egg noodles 340g
  • 1 can (10.5 ounces) condensed French onion soup 298g
  • 1 can (10.5 ounces) condensed cream of mushroom soup 298g
  • 1 cup sour cream 240ml
  • 2 cups sharp cheddar cheese 8oz or 225g, shredded, divided
  • 1 1/2 cups crispy French fried onions 170g, divided
  • 1 teaspoon Worcestershire sauce
  • 1/2 teaspoon dried thyme
  • Salt and pepper to taste
  • 2 tablespoons fresh parsley chopped, optional for garnish

Instructions
 

  • Preheat your oven to 350°F and lightly grease a 9x13 inch casserole dish with nonstick spray or butter.
  • Bring a large pot of salted water to a boil. Cook the egg noodles according to package directions, then drain and set aside.
  • Heat olive oil in a large skillet over medium-high heat. Cook the onion for 4-5 minutes until softened, then add the ground beef and cook until browned. Stir in garlic during the last minute.
  • Drain any excess grease, then reduce heat to medium-low. Add the French onion soup, cream of mushroom soup, Worcestershire sauce, and thyme. Stir until combined and let simmer for 2-3 minutes.
  • Remove from heat and stir in the sour cream until smooth. Fold in 1 cup of the cheddar cheese, then add the cooked noodles and gently fold until everything is coated.
  • Pour the mixture into the prepared casserole dish and spread into an even layer. Sprinkle the remaining 1 cup of cheddar cheese over the top.
  • Bake uncovered on the middle rack for 20 minutes, until the cheese is melted and the edges are bubbling.
  • Carefully remove from the oven and sprinkle the crispy French fried onions evenly over the top. Return to the oven and bake for 5-8 minutes more, until golden brown.
  • Let the casserole rest for 5-10 minutes before serving. Garnish with fresh parsley if desired.

Notes

  • Make ahead: Assemble the casserole up to a day ahead and refrigerate before baking. Hold off on adding the fried onion topping until just before baking.
  • Don't skip draining the beef: Excess grease can make the sauce feel heavy instead of creamy.
  • Cook noodles slightly under: Undercook the noodles slightly before baking so they don't turn mushy in the oven.
  • Shred your own cheese: Buy a block and shred it yourself for a meltier, more flavorful cheese than pre-shredded bags.
  • Add fried onions last: Add the crispy onions only in the final minutes of baking so they stay crisp instead of soggy.
  • Let it rest: Allow the casserole to rest before serving so the sauce sets and holds together neatly.
  • Storage: Refrigerate leftovers in an airtight container for up to 3 days.
  • Freezing: Freeze without the fried onion topping for up to 3 months. Thaw overnight in the refrigerator before reheating.
  • Variations: Swap ground beef for ground turkey, use Gruyère or Swiss cheese instead of cheddar, or add sliced mushrooms for extra depth.
  • Reheating: Reheat individual portions in the microwave in 30-second increments. For larger portions, reheat covered in a 325°F oven for about 20 minutes.
