How to Make Beef Stroganoff Casserole Recipe

Step 1: Prepare the Noodles

Start by preheating your oven to 350°F and boiling a large pot of salted water. Cooking the egg noodles according to the package directions ensures they’ll be perfectly tender but firm enough to hold up in the casserole. Once cooked, drain and set them aside while you prepare the savory beef mixture.

Step 2: Cook the Beef and Vegetables

In a large skillet over medium-high heat, brown the ground beef along with the diced onion and sliced mushrooms. This combination needs to cook until the meat is no longer pink and the veggies soften, releasing their flavors. The aroma that fills your kitchen during this step is simply unbeatable. Don’t forget to add minced garlic towards the end, cooking it just until fragrant to boost the dish’s savory depth.

Step 3: Make the Creamy Sauce

In a bowl, whisk together the mushroom soup, beef broth, milk, and Worcestershire sauce. Pour this mixture into your skillet with the cooked beef and veggies, bringing it to a gentle simmer. It’s important to simmer lightly so the flavors meld without scorching. Season with salt and pepper to taste for a perfectly balanced sauce that’s rich but not overwhelming.

Step 4: Combine and Bake

Remove the skillet from heat and stir in the sour cream to give the sauce that signature creamy tang. Then add the cooked egg noodles and toss everything together until every noodle is generously coated. Transfer this luscious mixture into a 9×13-inch baking dish, spreading it out evenly.

Step 5: Add the Crunch and Final Bake

Bake the casserole for 15 to 20 minutes, allowing the flavors to blend and the top to start bubbling. Next, sprinkle on the French fried onions—this little topping is the secret to a delightful contrast in texture. Pop it back into the oven for another 5 minutes or so, until the onions turn beautifully golden and crispy. Now, it’s ready to serve!

Make Ahead and Storage

Storing Leftovers

Once cooled, store any leftovers in an airtight container in the refrigerator. The Beef Stroganoff Casserole Recipe keeps well for up to 3 days, making it perfect for quick lunches or dinner the next day.

Freezing

You can freeze leftover casserole in a freezer-safe container for up to 2 months. To freeze, assemble the casserole as directed but do not add the French fried onions until after reheating, to maintain their crispiness.

FAQs

Can I use other types of noodles for this casserole?

Absolutely! While egg noodles are traditional and perfect for this Beef Stroganoff Casserole Recipe, you can swap in wide pasta like pappardelle or even penne. Just adjust cooking times accordingly.

You can substitute ground beef with ground turkey or chicken for a leaner version. Keep in mind that the flavor will be milder, so you might want to add extra seasoning or mushrooms to compensate.

Crumbled toasted breadcrumbs or crispy fried shallots make great substitutes and provide that essential crunchy topping for your casserole.

Is this recipe suitable for meal prepping?
