This oven baked 3-ingredient hot dog and potato casserole is the kind of simple, comforting dinner that stretches a budget and still feels satisfying at the end of a long day. It has that old-school, make-do charm that so many family recipes carry, with sliced hot dogs baked together with tender potatoes until the edges turn golden and cozy. Recipes like this became favorites for a reason: they use inexpensive basics, feed a family, and somehow always get eaten fast.
Serve this casserole with something fresh and crisp to balance the richness, like a simple green salad, coleslaw, or steamed green beans. If you want to make it feel a little heartier, a side of buttered peas, applesauce, or even plain toast works well. It also fits right in for a casual lunch with pickles or a spoonful of ketchup or mustard on the side for anyone who likes a little extra flavor.
Oven Baked 3-Ingredient Hot Dog and Potato Casserole
Servings: 4 to 6
Ingredients
1 1/2 pounds potatoes, peeled and thinly sliced
6 hot dogs, sliced into rounds
1 can (10 1/2 ounces) condensed cream of mushroom soup
Directions
1. Preheat the oven to 375°F and lightly grease a medium glass baking dish.
2. Peel the potatoes and slice them into thin, even rounds so they cook through evenly in the oven. Slice the hot dogs into bite-size coins.
3. Spread a thin layer of condensed soup on the bottom of the baking dish. Add half of the potato slices, then half of the hot dogs, and spoon over half of the remaining soup. Repeat the layers with the rest of the potatoes, hot dogs, and soup, spreading the soup as evenly as possible.
4. Cover the dish tightly with foil and bake for 45 minutes. Remove the foil and continue baking for 20 to 30 minutes more, or until the potatoes are tender when pierced with a fork and the top is lightly browned around the edges.
5. Let the casserole rest for 5 to 10 minutes before serving so it sets up slightly and is easier to scoop.
Variations & Tips
Add a little cheese: If you want to stretch beyond the original 3-ingredient version, sprinkle shredded cheddar over the top during the last 10 minutes of baking for a more classic casserole feel.
Use different soup: Cream of chicken or cream of celery both work nicely if that is what you have in the pantry. The texture stays creamy and the flavor changes just a bit.
Slice potatoes thinly: This is the biggest key to success. If the potato slices are too thick, the casserole may brown on top before the centers become tender.
Make it ahead: You can assemble the casserole earlier in the day, cover it, and refrigerate until ready to bake. If baking straight from the fridge, add a few extra minutes to the covered baking time.
Season at the table: Since hot dogs and condensed soup already bring quite a bit of salt, it is best to wait and taste before adding any extra seasoning. A little black pepper, ketchup, or mustard can be added individually when serving.
