Common Questions About Beef Stroganoff Casserole:
What Cut of Beef Should I Use?
Ground beef or stew meat works well, but 80/20 ground beef is highly recommended. The 80% lean and 20% fat ratio ensures flavorful and moist meat. Avoid using very lean ground beef (90/10 or higher), as it may lead to a drier casserole.
What If I Don’t Have Sour Cream?
Plain Greek yogurt is an excellent substitute for sour cream. Choose plain, unsweetened Greek yogurt for the best results. Use the same quantity as sour cream—1 cup of Greek yogurt for 1 cup of sour cream.
Can I Prep This Casserole Ahead of Time?
Absolutely! You can assemble the casserole in advance. Combine all ingredients—beef, onions, noodles, sauce, etc.—in a greased 9×13 baking dish. Cover tightly with plastic wrap and foil, and refrigerate for up to 24 hours before baking. When ready to cook, remove the coverings and bake as directed.
What Sides Pair Well with This Casserole?
Beef Stroganoff Casserole is delicious alongside a bright, crisp green salad. The crunchy greens balance the creamy casserole perfectly. For a heartier option, consider roasted vegetables like cauliflower, Brussels sprouts, broccoli, or carrots. Roasting caramelizes these veggies, adding color and texture to your plate.
Can I Use a Different Noodle?
Definitely! You can substitute other noodle shapes, such as rotini, farfalle, or ziti, instead of egg noodles. Just choose a short, sturdy pasta that can hold up during baking, and be sure to cook it al dente to avoid mushiness in the casserole.
How Long Will Leftovers Last?
This casserole can be stored in the fridge for 3-4 days in a sealed container. Reheat thoroughly until hot throughout. It also freezes exceptionally well! You can freeze individual portions or the entire casserole for up to 3 months. Thaw overnight in the fridge before reheating.

Instructions
- Preheat the Oven: Begin by preheating your oven to 350°F (175°C). Prepare a 9x13 inch baking dish by greasing it with butter or non-stick spray. Set the dish aside for later use. You’ll be baking this delicious casserole until it’s bubbly and golden brown!
- Cook the Ground Beef: In a large skillet over medium heat, add 1 pound of ground beef. Use a wooden spoon to break it apart as it cooks, stirring frequently until it’s completely browned and crumbled, which should take about 10 minutes. Drain any excess grease to keep the casserole lean and healthy.
- Sauté Onions and Garlic: Add 1 diced medium onion and 2 minced garlic cloves to the skillet with the cooked beef. Sauté for 3-4 minutes until the onions are translucent and fragrant, being careful not to let them brown too much.
- Combine Ingredients: Stir the beef and onion mixture well, then add 1/2 teaspoon salt, 1/4 teaspoon black pepper, 1 cup beef broth, 1 cup sour cream, 10.5 ounces of condensed cream of mushroom soup (1 can), and 1 tablespoon Worcestershire sauce. Allow this mixture to come to a simmer and let it bubble gently for about 5 minutes to meld the flavors.
- Cook the Egg Noodles: While the sauce simmers, cook 8 ounces of egg noodles in a pot of salted boiling water until al dente (about 2 minutes less than the package directions). Drain the noodles thoroughly to prevent them from becoming mushy.
- Assemble the Casserole: Transfer the saucy beef mixture to the prepared baking dish and fold in the cooked egg noodles. Spread the mixture evenly in the dish and top with 2 cups of shredded mozzarella cheese for a cheesy finish.
- Bake: Place the casserole in the preheated oven and bake uncovered for 25-30 minutes until it’s piping hot and bubbly. The cheese should be perfectly melted and lightly browned.
- Garnish and Serve: Remove the casserole from the oven and sprinkle with 2 tablespoons of chopped fresh parsley for a burst of color and freshness. Let it sit for 5 minutes before serving to avoid burning your mouth on hot cheese. Enjoy this hearty Beef Stroganoff Casserole with your family—they’ll be asking for seconds!
Notes
Choose the Right Ground Beef: For optimal moisture and flavor, use 80/20 ground beef. This fat ratio ensures a juicy and flavorful casserole. Cook Noodles Al Dente: Boil the egg noodles until they are just al dente. This prevents them from becoming mushy during baking and keeps your casserole perfectly textured. Adjust Sauce Consistency: If the sauce appears too thick, add a splash of milk or water to achieve your desired consistency. This will help create a creamy, delicious sauce. Cover While Baking: If the top of your casserole browns too quickly while baking, cover it with foil to ensure even cooking without burning the cheese on top. Garnish with Fresh Herbs: Instead of parsley, consider garnishing your casserole with fresh dill or chives for a unique flavor twist and vibrant presentation. Incorporate Extra Veggies: Boost the nutrition of your casserole by stirring in 1 cup of frozen peas or diced carrots. This adds color and extra vitamins to your dish. Add a Spicy Kick: For those who enjoy a little heat, incorporate 1/4 teaspoon of cayenne pepper to give your Beef Stroganoff Casserole a spicy flavor boost.
