Casseroles can seem old-fashioned, but there’s a reason they’re still so popular today. When it comes to classic comfort food, nothing else quite compares. They’re warm and homey and even the most up-to-date variations evoke a feeling of nostalgia that’s hard to beat.

Beef and noodles are a great casserole base. We made a beef noodle casserole before that uses a tomato sauce, but this time I wanted to see what would happen if I used a creamy gravy to make a Beef Stroganoff Casserole. The answer is something very, very good. The noodles soak up some of the sauce and take on so much flavor. I must have eaten at least a half serving just standing over the stove “taste testing.” It’s that good.

Of course, if you prefer something more traditional, you can always check out our classic casserole series, too!

Can beef stroganoff casserole be made ahead of time?

The beauty of casseroles is that they’re perfect for making ahead! This casserole is great for bringing to a potluck, gifting to a friend with a newborn, or just prepping ahead for yourself so you don’t have to think about cooking on a weeknight. You’ll need to bake the casserole a little longer if it’s been refrigerated, but we’ll address that in the recipe itself.

How to make beef stroganoff casserole

Making this casserole is very similar to making traditional beef stroganoff. You’ll start by sauteing mushrooms and onions and then adding ground beef and a creamy sauce. The main difference is that you’ll need to make more sauce than normal, since the noodles will absorb some of it. Also, you’ll add cheese. Because everything is better with cheese, right? Stir in cooked egg noodles, pour it all into your favorite casserole dish, top with more cheese, and bake it until it’s bubbling and lightly browned.

What kind of mushrooms should I use?

I love using sliced cremini mushrooms in recipes like this one. They have more flavor than white mushrooms, but not so much that they overpower the rest of the ingredients the way something like a portobello might. They’re also pretty easy to find in most grocery stores. You can usually buy them pre-sliced too, which saves a ton of time.
