Garlic (3 cloves): Adds a punch of aromatic flavor that elevates the entire dish.
Beef Broth (2 cups): Creates a savory foundation and enhances the meaty flavor. Use low-sodium for better control of seasoning.
Sour Cream (1 cup): Brings tangy creaminess that’s essential to traditional stroganoff.
Cream Cheese (4 oz): Adds body and velvety smoothness to the sauce, ensuring every bite is decadently creamy.
Worcestershire Sauce (2 tbsp): Deepens the umami flavor with subtle tang and spice.
All-Purpose Flour (2 tbsp): Thickens the sauce for that luscious, clingy texture you want in casseroles.
Olive Oil (2 tbsp): Used to brown the beef and sauté the vegetables, adding flavor at every layer.
Dried Thyme (1 tsp): Adds a herby aroma that complements the beef beautifully.
Mozzarella Cheese (1 cup): Melts into a golden, gooey topping—because every cheesy comfort food deserves it.

Pro Tips for Perfect Results

Slice Beef Thinly: Cutting the beef against the grain ensures tenderness and easy chewing.
Brown in Batches: Don’t overcrowd the pan—sear in small batches for deep, caramelized flavor.
Cool Sauce Before Adding Dairy: Prevent curdling by removing the skillet from heat before stirring in sour cream and cream cheese.
Use Freshly Shredded Cheese: It melts better and avoids the waxy texture of pre-shredded cheese.
Let It Rest: Allow the casserole to cool for 5–10 minutes after baking. It helps the sauce thicken and the flavors develop.
