French Onion Beef Casserole

Our French onion beef casserole combines savory ground beef, egg noodles, and French onion dip to create a warm and filling dish.

Over the years, Kim and I have shared a lot of different casseroles. A quick search on our site will give you plenty of options.

For example, you’ll a find a chicken Doritos casserole, a creamy chicken noodle casserole, easy tuna casserole, chicken spaghetti, spaghetti pie (kind of like a casserole) and even a crescent roll breakfast casserole.

Today, we’re adding to that list with our new French onion beef casserole using ground beef.

It’s a rich, creamy casserole dish that’s warm and filling. Imagine a Hamburger Helper skillet casserole with a French onion twist.

Try this recipe on a cold day and you won’t be disappointed! So, shall we get started?

How to make French onion beef casserole?

First, preheat your oven to 350 degrees F. and grease a 9×13-inch casserole dish with non-stick cooking spray.

After that, pre-cook the egg noodles using the package directions. See the tips section below to avoid mushy noodles.

Once they’re done, drain the noodles and chill them will cold tap water to stop the cooking process.

Next, place the ground beef and Worcestershire sauce into a large skillet and cook the beef over low-medium heat.

When the ground beef has completely cooked, drain the excess grease and return the meat to the skillet.

You’ll still use low-medium heat for the following steps of the recipe.

This one is a keeper! I used golden mushroom soup instead of cream of mushroom (just don't like it) and I added a generous 1/2 cup of half and half to the mixture so it wouldn't be too dry. I used mozzarella cheese because that's all I had on hand, but I'm definitely going to try a swiss/gruyere blend next time since I think it would blend best with the other flavors. Everyone loved it, even the picky kid!

Since the recipe is enough to fill a 13x9, I split it into two 8x8s...one for now, and one for the freezer.

Can you make the French onion homemade dip using the French onion soup packets and then use that in the casserole?

Hi Danielle!

We haven't tested that and can't say for sure how it would work. My concern would be that it might separate as the casserole bakes since it's not pre-mixed. However, it may work great! If you decide to try it, we'd love to know how it works out. Enjoy the rest of your weekend! :)

Holy crap this was AMAZINGA. I honestly could have eaten the noodle mixture as a dish alone, but the cheese and those crispy onions took it to another level. 10/10

Is the initial bake period covered, or uncovered? I assume uncovered as it doesn't say either way.

Hi Michelle!

It's uncovered. Thanks for asking!
