Ingredients for Your Hobo Casserole
Let's gather the straightforward components for this hearty meal.
Ground Beef: 1 lb (about 500g) of lean ground beef.
Potatoes: 4-5 medium potatoes, peeled and thinly sliced (about ⅛-inch thick).
Irish potatoes work perfectly. Onion: One large onion, chopped.
Garlic: 2-3 cloves, minced.
Cream of Mushroom Soup: One (10.5 oz / 300g) can.
This is the classic shortcut for creating an instant creamy and savory sauce. Substitution: Cream of chicken or cream of celery soup would also work. Beef Broth: ½ cup of beef broth or stock. This helps thin the soup into a perfect sauce consistency.
Worcestershire Sauce: 1 tablespoon, for a deep, savory flavour.
Shredded Cheese: 1-2 cups of a good melting cheese, like Cheddar or a blend.
Seasoning: Salt, black pepper, and a pinch of dried thyme or oregano.
Optional Garnish: Freshly chopped parsley or green onions.
How to Make Hearty Hobo Casserole
1. Prep Your Ingredients: Preheat your oven to 375°F (190°C). Lightly grease a 9x13 inch baking dish. Peel and slice your potatoes thinly and evenly.
2. Brown the Beef: In a large skillet over medium-high heat, cook the ground beef with the chopped onion until the meat is browned and the onion is soft. Add the minced garlic and cook for another minute until fragrant. Drain off any excess fat from the skillet.
3. Create the Creamy Sauce: To the skillet with the beef, stir in the can of cream of mushroom soup, beef broth, Worcestershire sauce, salt, pepper, and dried thyme. Mix until everything is well combined and heated through.
4. Assemble the Casserole: Arrange half of your thinly sliced potatoes in a single, slightly overlapping layer in the bottom of your prepared baking dish. Spoon half of the ground beef mixture evenly over the potatoes. Repeat with a final layer of the remaining potatoes, followed by the rest of the beef mixture.
5. Bake to Tender Perfection: Cover the baking dish tightly with aluminum foil. This is a crucial step as it traps the steam, which cooks the potatoes until they are perfectly tender. Bake for 45-55 minutes.
6. The Cheesy Finish: Carefully remove the foil. The potatoes should be tender when pierced with a fork. Sprinkle the shredded cheese evenly over the top of the casserole. Return the dish to the oven, uncovered, and bake for another 10-15 minutes, or until the cheese is completely melted, bubbly, and starting to turn golden brown.
7. Rest and Serve: Let the casserole rest for about 10 minutes before serving. This allows the sauce to set slightly, making it easier to serve. Garnish with fresh parsley, if desired.
Make-Ahead & Storage Tips
Make-Ahead: You can assemble the entire casserole (without baking), cover it, and store it in the refrigerator for up to 24 hours. You may need to add about 15 minutes to the initial covered baking time.
Storage: Store leftovers in an airtight container in the refrigerator for up to 4 days.
Freezing: This casserole freezes well! You can freeze it either baked or unbaked. If unbaked, thaw overnight in the fridge before baking as directed.
Variations
Add More Veggies: Feel free to mix in a cup of frozen corn, peas, or sliced carrots with the ground beef mixture for an extra nutritional boost.
Change the Soup: Not a fan of mushroom? Use cream of chicken soup for a different creamy profile, or even a can of cheddar cheese soup for an ultra-cheesy version.
Spice It Up: For those of us who love a bit of heat, a finely chopped fresh chili (like ata rodo) can be added to the ground beef along with the onions.
Tater Tot Topping: For a fun twist, omit the top layer of sliced potatoes and arrange a single layer of frozen tater tots over the beef mixture before baking.
Expert Tips for Success
Slice Potatoes Thinly: The key to perfectly cooked potatoes is slicing them thinly and evenly. A mandoline slicer is great for this, but a sharp knife works just fine.
Don't Skip Covering: Baking the casserole covered is essential. The trapped steam ensures the raw potatoes cook through and become tender and delicious.
The Fork Test: The easiest way to check if the casserole is ready for the cheese topping is to pierce a potato in the center with a fork. It should go in with very little resistance.
Let It Rest: That 10-minute rest after baking makes all the difference. It helps the layers firm up, so you can serve neat, beautiful portions instead of a soupy pile.
Hobo Casserole FAQs
Do I need to cook the potatoes before layering them? No, and that’s the beauty of this recipe! As long as you slice them thinly and bake the casserole covered, the potatoes will cook perfectly in the sauce.
Can I use a different type of potato? Yes. While standard Irish potatoes work great, waxy potatoes like red potatoes or Yukon Golds are also fantastic as they hold their shape very well during baking.
I don't have canned soup. Is there a substitute? You can make a simple homemade cream sauce. In a saucepan, melt 3 tablespoons of butter, whisk in 3 tablespoons of flour to make a roux, then slowly whisk in 1 ½ cups of milk or broth until thickened. Season well with salt, pepper, and a pinch of thyme.
