Ingredients
1 1/2 pounds ground beef
Ground beef provides the hearty, savory foundation of the casserole. Browning it first develops deeper flavor while allowing excess grease to be drained before the mixture goes into the oven.
1 medium onion, thinly sliced
The onion adds sweetness and savory depth. As it cooks with the beef, it softens and blends into the casserole, giving the finished dish more flavor without requiring additional seasonings.
1 can (10 3/4 ounces) condensed tomato soup
Condensed tomato soup is the shortcut ingredient that brings everything together. It adds tomato flavor, moisture, and a creamy-saucy texture, helping the beef mixture stay tender and flavorful as it bakes.
2 cups shredded cheddar cheese
Cheddar creates the irresistible golden, melty topping. It adds richness and a familiar sharpness that balances the savory beef and tomato base.
How to Make Ground Beef Wentworth
1. Prepare the oven and baking dish
Preheat your oven to 350°F. Lightly grease a 9×13-inch glass baking dish so the casserole is easy to serve once baked.
2. Brown the beef and onion
Place a large skillet over medium heat. Add the ground beef and sliced onion and cook until the beef is completely browned and the onion has softened.
Break the beef apart as it cooks so you end up with evenly sized pieces throughout the casserole. Drain away any excess grease.
3. Add the tomato soup
Stir the condensed tomato soup into the browned beef and onion mixture. Continue stirring until everything is evenly coated and heated through.
This simple combination becomes the flavorful base of the casserole.
4. Assemble the casserole
Spoon the beef mixture into the prepared baking dish. Spread it into an even layer so the casserole cooks consistently from edge to center.
Sprinkle the 2 cups of shredded cheddar cheese evenly over the top.
5. Bake until bubbly
Place the uncovered casserole in the preheated oven and bake for 20 to 25 minutes.
You are looking for a casserole that is hot and bubbling, with the cheddar completely melted and lightly browned around some of the edges.
6. Let it rest
Remove the casserole from the oven and let it rest for about 5 minutes before serving.
That short resting period allows the saucy filling to settle slightly, making it easier to scoop onto plates without the casserole immediately spreading apart.
Pro Tips for the Best Ground Beef Wentworth
Drain the beef well. Removing excess grease after browning keeps the casserole from becoming unnecessarily oily while allowing the tomato soup and cheddar to remain the stars.
Don’t overbake it. Once the cheese is melted and the casserole is bubbling, it is ready. Too much oven time can dry out the beef mixture.
Shred your own cheddar when possible. Freshly shredded cheese melts smoothly and gives the casserole that beautiful gooey topping.
Finely chop the onion for picky eaters. Instead of larger slices, dice the onion very small. It will soften into the beef mixture and become much less noticeable.
Add seasoning only if desired. The original four-ingredient spirit of the recipe is part of its charm, but a little black pepper or garlic powder can be added if you want extra flavor.
Make it ahead. Brown the beef and onion earlier in the day, stir in the tomato soup, and refrigerate the mixture. When you’re ready for dinner, transfer it to the baking dish, add the cheese, and bake until thoroughly hot and bubbly.
Easy Variations
Change the cheese
Cheddar is the classic choice, but Colby Jack, Monterey Jack, or a mild cheddar blend can also work beautifully. For a stronger flavor, use a sharp cheddar.
Make it extra filling
Serve the beef mixture over mashed potatoes, cooked egg noodles, or rice. This is especially useful when you need to stretch the casserole to feed a larger family.
Make the onion milder
Finely dice the onion instead of slicing it. It will practically melt into the beef while cooking.
Add a little extra seasoning
For a slightly more seasoned version, add a pinch of black pepper, garlic powder, or your favorite mild dried herbs. Keep the additions subtle so the simple character of the original recipe remains intact.
What to Serve With Ground Beef Wentworth
This old-fashioned ground beef casserole is hearty enough to stand on its own, but a few simple sides turn it into a complete comfort-food dinner.
Try serving it with:
– Buttery green beans
– Sweet corn
– Roasted carrots
– A crisp garden salad

For a cozy harvest-season supper, mashed potatoes and green beans make an especially comforting combination. If you’re serving it at a casual potluck, simply cut or scoop portions directly from the baking dish and let the cheesy topping speak for itself.
Frequently Asked Questions
Can I make this casserole ahead of time?
Yes. Prepare the beef, onion, and tomato soup mixture ahead of time and refrigerate it. Add the cheese just before baking, then bake until the casserole is completely hot and bubbling.

How can I make it stretch further?
Serve the casserole over rice, egg noodles, or mashed potatoes. These additions turn the savory beef mixture into an even more substantial family meal.
