Leftover Noodles Casserole

Total Time
Prep 15 mins
Cook 40 mins

I make this when I have left-over, cooked lasagna noodles. I just slice them up and use them like any cooked pasta noodle. This is good at room temperature or as leftovers. You can use a commercially-made, dry onion soup mix or make your own, Copycat Lipton's Onion Soup Mix (that's what I use).

Ingredients Nutrition

  • 3 cups noodles, cooked
  • 2 tablespoons ghee or 2 tablespoons butter
  • 12 cup green pepper, chopped
  • 12 cup celery, chopped
  • 12 cup onion, chopped
  • 3 eggs, beaten
  • 1 cup any shredded cheese
  • 34 cup sour cream
  • 34 cup milk
  • 2 12 tablespoons onion soup mix (or 1/2 of an envelope)
  • 12 teaspoon salt (if NOT using commercial onion soup)
  • 2 tablespoons breadcrumbs, for topping (optional)


  1. Melt ghee in saucepan.
  2. Add the peppers, celery and onions and cook til soft. Remove from heat.
  3. In a large bowl, combine the eggs, cheese, sour cream, milk, soup mix, salt.
  4. Add the cooked vegetables, scraping the pan to get all the melted butter. Combine.
  5. Add the noodles and mix well.
  6. Pour into a greased 2-quart casserole.
  7. Sprinkle with bread crumbs and dot with ghee if desired.
  8. Bake 350 degrees for 40-minutes or until a test knife comes out clean.
  9. Let cool for 20-minutes and serve.

Leftover noodles? In my house? You have got to be kidding me! I'm lucky if I can keep enough of the drained and rinsed noodles around long enough until the sauce has been prepared. Keeping that in mind, and knowing how much the family loves noodle dishes, I just prepared the sauce first (as per the recipe) and then cooked up a batch of noodles to go with the sauce. Can I review a recipe entitled Leftover Noodles Casserole when I am not using Leftover Noodles? For argument's sake, let's pretend I can. And on to my review: I didn't really measure the vegetables, just tossed in the trinity of peppers, celery and onions. I used a strongly flavored local yellow cheese and a full cup of sour cream. I also mixed some of the shredded cheese with the breadcrumbs for an extra-crunchy topping. In our house, people fight over crunchy topping! All in all, good stuff!

This was very good. But I did make some changes according to what I had on hand. I used coconut oil only because it is so good for "you". I also used frozen broccoli because I didn't have celery and a few cloves of garlic. I sauteed all of this and caramelized the veggies a bit. I also used plain greek yogurt for the extra good for "you" stuff and because I didn't have an onion soup mix I used vegetable recipe mix from Knorr. My children are 7 & 10 and they mmm mmm loved it ;) My husband had seconds & my daughter wants to take it for lunch tomorrow at school. Definitely a keeper recipe. Oh, and for the topping I used crunched up potato chips added extra chopped up cheddar as another suggestion was given(good one) and Parmesan cheese and because my family loves garlic I added a bit of store bought minced garlic and added it the last 15 minutes of baking to get it really crispy.
Thanks for the ideas...

Since I never have leftover noodles, I made rotelle (corkscrew) noodles just for this. Great flavor! Nice balance of creaminess and veggies. I used red bell pepper instead of green for some extra color. My milk and sour cream were reduced fat. I'll certainly make this again....leftover noodles or not! I think muchrooms would be a great addition to this and I'm going to try that. Thanx for sharing!
