How to make beef stroganoff casserole

Print this recipe
Beef stroganoff is one of those dishes that everyone looks to when they need a helping or two of comfort. But when that comfort is needed, no one wants to have to stand in front of a stove whipping it up first. Enter this casserole, which brings all the creamy goodness of beef stroganoff, complete with the rich and earthy flavor of beef and mushrooms.
To prepare this classic dish for casserole form, a few adaptations are needed on the traditional recipe. Most people include canned mushroom soup but to keep things as fresh as possible, this recipe uses a basic bechamel, with mushrooms as the base. And in place of the lean strips of beef, which can quickly dry out when frozen or cooked for a long period, ground beef is used, and it's much more forgiving.

The recipe is written for one casserole, but a great way to save on time and take advantage of bulk pricing is to prep 2 or 3 casseroles. Eat one the first night, and freeze the rest for those days when you need a break from prepping food. Future you will thank you for it.

Beef Stroganoff Casserole
6
25 minutes
35 minutes
60 minutes
1 12-ounce package egg noodles
1 tablespoon (15 ml) olive oil
1 pound (450 grams) lean ground beef
1 cup (250 ml) mushrooms, roughly chopped
1 shallot, diced
3 cloves garlic, minced
¼ cup (60 ml) butter
¼ cup (60 ml) all-purpose flour
1 cup (250 ml) mushroom stock
1 cup (250 ml) milk
Pinch of nutmeg
½ cup (125 ml) sour cream
1 tablespoon (15 ml) Dijon mustard
Salt, to taste
Freshly ground black pepper, to taste
Preheat oven to 350 degrees Fahrenheit (180 degrees Celsius).
Bring a large pot of water to a rapid boil. Generously salt, add egg noodles, and cook for about 5 minutes, until they are just al dente, stirring regularly. Drain well and set aside in a large bowl.
While the egg noodles are cooking, heat olive oil in a large skillet set over medium heat. Add ground beef, breaking it up as you do, and cook until beef is no longer pink.
Add the mushrooms to the pan and toss to coat in the fat. Add the shallot and the garlic, stir, and season with salt and pepper. Cook for about 8 minutes, until the mushrooms have softened and are just beginning to brown.
Add the butter to the pan, let butter melt, then add flour and whisk to thoroughly combine. Cook for 2 minutes to let the raw flour cook out. Slowly add in the mushroom stock, whisking as you do to break up any clumps. Whisk in the milk, add the nutmeg, and season with salt and pepper. Let the mixture cook for another 5 minutes or so, just until it has thickened slightly.
Add the sour cream and Dijon mustard to the bowl with the other ingredients and stir thoroughly. Taste, and adjust seasoning if necessary. Add the cooked noddles and stir until well combined.
Pour the mixture into a 9" x 13" casserole dish, cover with foil. If you're going to use this as a make-ahead meal and want to freeze it, now is the time to do so. Before cooking, let the entire casserole come to room temperature than proceed to next step.
Place into the preheated oven. Bake for 45 minutes or until the mixture is hot and bubbling throughout.
If you want to add cheese to the casserole, remove foil halfway through cooking time and sprinkle it over top. Continue to cook for remainder of cooking time.
