Irresistible Beef Stroganoff Casserole in Just 30 Minutes

Oh my gosh, you guys – this beef stroganoff casserole is my ultimate comfort food hack! I first made it years ago when my cousin brought over unexpected dinner guests, and now it’s my go-to for every potluck, busy weeknight, or “I need something cozy” moment. The way those egg noodles soak up the creamy sauce? Absolute perfection.

What I love most is how it takes all the rich, savory flavors of classic beef stroganoff and turns them into the easiest baked casserole you’ll ever make. No standing over the stove stirring – just brown the beef, mix everything together, and let your oven do the work. It’s the kind of dish that makes everyone at the table go quiet except for the happy “mmm” sounds.

My grandma used to say good food should hug you from the inside, and this casserole does exactly that. The melty cheese on top, the tender noodles underneath, and that creamy stroganoff sauce tying it all together? Pure edible comfort. And the best part? Leftovers taste even better the next day (if you’re lucky enough to have any!).

The Beefy Goodness

• 1 lb ground beef (80/20 works best for flavor)
• 1 small onion, diced (yellow or white – whatever’s in your pantry)
• 2 cloves garlic, minced (or 1 tsp jarred if you’re in a rush)

The Creamy Dream Team

• 1 can cream of mushroom soup (don’t dilute it!)
• 1 cup sour cream (full-fat recommended for that luscious texture)
• 1/2 cup milk (whole milk makes it extra rich)
• 1 tbsp Worcestershire sauce (that secret umami boost)

The Noodle Situation

• 8 oz egg noodles (the wide, curly ones hold sauce best)

The Cheesy Finish

• 1 cup shredded cheddar cheese (sharp cheddar gives the best flavor pop)
• Fresh parsley for garnish (optional but pretty)

See? Nothing fancy – just good, honest ingredients that come together into something magical. Now let’s get cooking!

How to Make Beef Stroganoff Casserole

Step 1: Cook the Noodles

First, get those egg noodles boiling in salted water. Cook them just until al dente – about 1 minute less than the package says. They’ll finish cooking in the oven, and nobody wants mushy noodles! Drain them well and set aside.

Step 2: Brown the Beef

While the noodles cook, brown your ground beef in a large skillet over medium heat. Break it up as it cooks – I like using a potato masher for this! When the beef is nearly done, add the onions and garlic. Cook until fragrant and the onions turn translucent. Drain any excess fat (but leave a little for flavor!).

Step 3: Mix the Stroganoff Sauce

Now for the magic! Stir in the cream of mushroom soup, sour cream, milk, Worcestershire sauce, and seasonings right into the beef mixture. Keep the heat low – you just want everything warmed through and combined. The smell at this point? Absolute heaven.

Step 4: Assemble and Bake

Grease a 9×13 baking dish and spread the cooked noodles evenly on the bottom. Pour the beef mixture over top, spreading it gently to cover all the noodles. Sprinkle that glorious cheddar cheese over everything – be generous! Bake at 375°F for 20-25 minutes until bubbly around the edges and golden on top. Let it rest for 5 minutes before serving (the hardest part!).

See? Simple as can be! Now grab a fork and dig into that creamy, beefy, cheesy goodness.

Tips for the Best Beef Stroganoff Casserole

Here are my tried-and-true secrets for taking this casserole from good to “Oh my gosh, can I have the recipe?!” good:

• Freshly grate your cheese – pre-shredded stuff doesn’t melt as beautifully (and has weird anti-caking agents)
• Sneak in mushrooms if you’re feeling fancy – sauté them with the onions for extra umami
• Let it rest 5 minutes after baking – this helps the sauce thicken up perfectly
• Double the recipe and freeze one – you’ll thank yourself on busy nights!
• Toast your breadcrumbs for the topping if you want extra crunch (my grandma’s trick)

Little touches make all the difference with comfort food classics like this!

Make-Ahead and Storage Instructions

This beef stroganoff casserole is practically made for meal prep! You can assemble the whole dish up to 2 days ahead – just cover tightly and refrigerate until you’re ready to bake. Add 5-10 extra minutes to the baking time since it’ll be cold from the fridge.

Leftovers? They’re even better! Store cooled portions in airtight containers for 3-4 days in the fridge. Reheat individual servings in the microwave (stir halfway through) or pop the whole dish back in the oven at 350°F until warmed through.

Freezer tip: Assemble without the cheese topping, wrap well, and freeze for up to 3 months. Thaw overnight in the fridge, add cheese, and bake as directed. Perfect for emergency comfort food cravings!

Serving Suggestions for Beef Stroganoff Casserole

Oh, the possibilities! This casserole plays so nicely with others. My favorite way to serve it? With a crusty loaf of garlic bread for sauce-dipping and a simple green salad to cut through the richness. Roasted Brussels sprouts or honey-glazed carrots make fabulous veggie sides too.

At potlucks, I’ll often bring this alongside my famous cornbread muffins and a big bowl of tangy coleslaw. The combo disappears every time! For a heartier meal, add a baked potato bar setup – let everyone load up their plates with stroganoff-topped spuds. Pure comfort food heaven.
