This corned beef and noodle casserole is a delicious way to use the leftover corned beef, and it's a meal in one dish. Serve this easy corned beef casserole with a tossed salad and cornbread or biscuits for a hearty meal.

Though leftover or deli corned beef will have the best flavor and texture, this casserole can be made with canned corned beef as well. When I made it recently to update the photo, I used canned. I added it to the noodle mixture cold, without browning it first. 
 

What You'll Need

  • 8 ounces medium or wide egg noodles
  • 4 tablespoons butter, divided
  • 1 cup chopped onion
  • 2 1/2 to 3 cups diced corned beef, about 12 ounces
  • 16 ounces chopped frozen spinach, thawed, excess water squeezed out
  • 3 tablespoons all-purpose flour
  • 1/2 teaspoon ground mustard
  • 1 cup chicken broth
  • 1 cup milk (low-fat is fine)
  • 1/8 teaspoon black pepper
  • 1/4 teaspoon dried leaf thyme
  • 2 cups shredded sharp Cheddar cheese
  • 1/2 teaspoon salt, or to taste
  • 1/2 to 1 cup French fried onion rings or buttered bread crumbs, optional

How to Make It

  1. Heat the oven to 350 F (180 C/Gas 4). Butter a 2 1/2-quart baking dish.
  2. Using a large saucepan or stock pot, cook the noodles following package directions; drain well. Put noodles back in the pot or in a large bowl and set aside.
  3. In a medium saucepan, melt 2 tablespoons of butter over medium heat; cook the chopped onion for 2 minutes. Add the corned beef and cook until lightly browned. With a slotted spoon, transfer beef and onion mixture to the pot with noodles. Add the squeezed spinach to the pot and set aside.
  1. In the same medium saucepan, melt the remaining 2 tablespoons butter over medium-low heat; stir in the 3 tablespoons of flour and the mustard powder until well blended and bubbly. Continue cooking, while stirring, for 2 minutes. Gradually stir in chicken broth and milk. Cook, stirring constantly, until thickened and bubbly. Add pepper and thyme. Stir in the cheese, cooking until melted. Add salt to taste.
  2. Pour the sauce over the noodle and corned beef mixture and gently stir until well blended.
  3. Spoon the corned beef and noodle mixture into the prepared baking dish.
  4. If desired, top with crumbled French fried onions or buttered bread crumbs.
  5. Bake for 25 to 30 minutes, or until hot and bubbly and the topping is lightly browned.

Reader Comments and Suggestions

  • "Kids were a bit aghast at having corned beef five nights in a row, ( we had our own, then were given some as well) but boy were they happy when I served this one up. No more boring corned beef dinners - they told me to make it again tonight! It is so yummy, and I could easily take a portion out for my dairy allergic daughter before adding the cheese. Baked hers in a separate dish. Freshly whizzed breadcrumbs on top were yum too." Jules
  • "I searched high and low for a recipe other than "hash" to use up my leftover corned beef, and I really liked this one. I used about half the amount of cheese and found that adequate, and would recommend adding the breadcrumbs or something for the top, so the noodles don't dry out and harden. Also, I didn't add any salt, as between the corned beef and cheese, this seemed to be already high enough in saltiness. I will definitely make this again." Gina
