Old Fashioned Mushroom & Swiss Cheeseburger Casserole

The 2nd ingredient makes this truly irresistible….

What are your thoughts on a good ol’ fashioned mushroom Swiss cheese burger? You know, a nice hearty beef patty that’s topped with perfectly seasoned and sautéed mushrooms, covered by a healthy smattering of Swiss cheese. Yum, yum, yum. Even if you’re not a fan of mushrooms, we think this dish could win just about anyone over. But, you know the one bad thing about a mushroom burger? It’s over way too soon, plus, in order to make them at home you’d have to spend time grilling each burger while the others get cold. No, thank you.

DIRECTIONS:

Stir in minced garlic and cook for 1-2 minutes, or until fragrant, then season with Italian seasoning.

Add ground beef and cook until browned, then drain fat, if necessary, and mix in Worcestershire sauce, cream of mushroom soup and heavy whipping cream.

Reduce heat to medium and continue cooking for another 3-5 minutes, giving flavors a chance to blend, then stir in potato dumplings and cook for another 5 minutes …
