This 5-ingredient oven baked beef is the kind of cozy, no-fuss casserole that busy families rely on. You literally dump raw ground beef into the casserole dish, pour over a simple creamy mixture, add a few pantry staples, and let the oven do the work. It’s inspired by the old-fashioned Midwest “dump-and-bake” suppers many of us grew up with—simple, hearty, and comforting. The result is a savory, creamy beef bake that’s rich, satisfying, and easy enough for a hectic weeknight, but tasty enough that everyone will be asking for seconds.
Serve this creamy baked beef over fluffy mashed potatoes, buttered egg noodles, or steamed white rice so all that savory sauce has something to soak into. A simple green side salad, steamed green beans, or roasted broccoli balances the richness nicely. Warm dinner rolls or garlic bread are great for scooping up the extra sauce, and if you’d like to round things out, a side of applesauce or sliced fresh fruit keeps the meal feeling homey and kid-friendly.
5-Ingredient Oven Baked BeefServings: 4
Ingredients
1 1/2 pounds raw ground beef (80–90% lean)
1 (10.5-ounce) can condensed cream of mushroom soup
1 cup sour cream
1 (1-ounce) packet dry onion soup mix
1 cup shredded cheddar cheese
Directions
Preheat your oven to 375°F (190°C). Lightly grease a 9x13-inch oven-safe casserole dish with cooking spray or a thin swipe of oil.
Break the raw ground beef into small, even chunks and scatter them across the bottom of the casserole dish. Use clean hands or a spoon to spread it into a loose, even layer; it does not need to be perfectly flat or packed down.
In a medium bowl, stir together the condensed cream of mushroom soup, sour cream, and dry onion soup mix until the mixture is smooth and well combined. This should look like a thick, creamy sauce.
Pour the creamy mixture evenly over the raw ground beef in the casserole dish. Use a spatula or the back of a spoon to gently spread it so all of the beef is covered in the sauce. You should see the raw beef peeking through in places, surrounded by the creamy liquid.
Cover the casserole dish tightly with aluminum foil. Bake in the preheated oven for 30 minutes to allow the beef to cook through gently and release its juices into the sauce.
Carefully remove the foil, stir the casserole well to break up the beef and mix it into the sauce, then smooth it back into an even layer. Sprinkle the shredded cheddar cheese evenly over the top.
Return the uncovered casserole to the oven and bake for another 15–20 minutes, or until the cheese is melted, bubbly, and the beef is fully cooked through (no pink remains and the mixture is hot and bubbling around the edges).
Let the casserole rest for 5–10 minutes before serving so the sauce can thicken slightly. Spoon the creamy baked beef over mashed potatoes, egg noodles, or rice, and enjoy.
Variations & Tips
For picky eaters, you can swap cream of mushroom soup for cream of chicken or cream of celery if they don’t like mushroom pieces. If onions are a hard no, replace the dry onion soup mix with 1 teaspoon garlic powder, 1 teaspoon dried parsley, and 1/2 teaspoon salt for a milder flavor. For a slightly lighter version, use light sour cream and leaner ground beef, and drain off any excess fat after the first 30 minutes before stirring and adding cheese. To stretch this meal for a bigger family, stir in 1–2 cups of cooked egg noodles, cooked rice, or frozen mixed vegetables (like peas and carrots) after the first bake, then top with cheese and finish baking. For extra crunch, add 1/2–1 cup of crushed butter crackers or French-fried onions on top of the cheese before the final bake. If you like a bit of zip, mix in 1/4 cup salsa or a pinch of red pepper flakes into the creamy mixture. This recipe also reheats well, so you can double it and bake in two smaller dishes—serve one tonight and cool, cover, and refrigerate the other for an easy reheat later in the week.
