Easy One Pan Hobo Casserole With Ground Beef, Potatoes, Carrots, Green Beans, and Cheesy Mushroom Sauce for the Ultimate Comfort Meal

There are certain dishes that feel like a warm hug, the kind of comfort food that families have been making for decades because they’re hearty, affordable, and always delicious. The easy one pan hobo casserole is one of those timeless meals.

Born out of the idea of combining simple, humble ingredients into one filling dish, this casserole is as practical as it is mouthwatering.

With layers of tender potatoes, sweet carrots, savory ground beef, crisp green beans, and a creamy mushroom sauce topped with bubbling cheddar cheese, every bite is a little taste of home.

This dish has roots in campfire cooking traditions where “hobo meals” were wrapped in foil and cooked directly over the fire. Over time, families adapted the concept for their ovens, making the casserole a staple in weeknight cooking. It’s hearty enough to feed a crowd but simple enough for any night of the week.

A Casserole With History and Heart 

Hobo-style meals date back to the Great Depression and the era of train travelers, when resourceful cooks made the most of inexpensive and available ingredients.

Potatoes, ground beef, and canned vegetables were easy to find, inexpensive, and kept well without refrigeration.

Over time, casseroles like this became popular in American kitchens, especially during the mid-20th century, when canned soups and one-dish dinners became a household trend.

Time and Money Saving Tips

• Use a mandoline slicer for evenly thin potatoes—this cuts prep time dramatically.

• Buy pre-shredded cheese and pre-sliced carrots to save chopping time.

• Double the recipe and freeze one casserole for later—you’ll thank yourself on a busy night.

Fun Facts About Hobo Casserole 

Did you know the name “hobo casserole” often changes depending on the family? Some call it “poor man’s casserole,” while others just know it as “the casserole grandma always made.” The unpretentious charm is part of the appeal.

Another fun fact: while canned green beans are traditional, many modern recipes swap in frozen or fresh vegetables to lighten things up. The beauty of this dish lies in its adaptability—it welcomes substitutions without ever losing its soul.
