Swiss Smashburger Stroganoff

 

A rich, one-pan comfort dish that blends the crave-worthy flavor of a mushroom Swiss burger with the silky luxury of beef stroganoff.

---

Why This Dish Works

• Ground beef seared like a smashburger gives maximum flavor with caramelized bits.

• A silky Swiss cheese béchamel replaces traditional sour cream, for that melty burger richness.

• Sautéed mushrooms and onions bring the umami, layered like they would be on a classic diner burger.

• Served over buttered egg noodles or mashed potatoes for the stroganoff experience.
