Mama kept this clipping from a 1965 ladies’ auxiliary cookbook tucked inside her wooden recipe box, its edges softened from years of use. It was one of those wonderfully practical recipes that didn’t need a long ingredient list or complicated instructions to put a satisfying dinner on the table.
This 3-ingredient meatloaf combines ground beef, dry onion soup mix, and shredded cheddar cheese into a savory, hearty loaf with a beautifully browned exterior and a tender, cheesy center. The onion soup mix provides plenty of savory seasoning, while the cheddar melts into the beef for extra richness and flavor.
It is the kind of old-fashioned meatloaf recipe that feels made for busy weeknights: inexpensive, comforting, easy to prepare, and made with ingredients that require almost no preparation. Serve it with mashed potatoes and green beans, and you have the sort of classic family dinner that needs very little else.
Ingredients
1 ½ pounds ground beef
The ground beef forms the hearty foundation of the meatloaf. A moderately lean ground beef works especially well because it provides enough fat for tenderness without leaving the loaf excessively greasy.
1 packet dry onion soup mix
This is the recipe’s shortcut to big flavor. Dry onion soup mix brings savory onion flavor and seasoning throughout the meatloaf without requiring fresh onions, garlic, or a long list of spices.
2 cups shredded cheddar cheese
Cheddar adds richness, moisture, and a deliciously savory flavor. As it melts during baking, it helps give the meatloaf a tender interior and pockets of cheesy goodness.
How to Make 3-Ingredient Meatloaf
1. Prepare the oven
Preheat your oven to 350°F. Lightly grease a glass baking dish or loaf pan so the meatloaf releases easily after baking.
2. Combine the ingredients
Place the ground beef, dry onion soup mix, and shredded cheddar cheese in a large bowl.
Using clean hands or a spoon, gently mix everything together until the ingredients are evenly distributed. Avoid excessive mixing, which can make the finished meatloaf unnecessarily dense.
3. Shape the loaf
Transfer the mixture to the prepared baking dish. Shape it into a thick, even loaf, gently pressing the mixture together so it holds its shape while baking.
4. Bake
Place the dish in the preheated oven and bake for approximately 50 to 60 minutes, or until the meatloaf is browned and cooked through.
If there is a significant amount of rendered grease in the dish, carefully spoon some away during the final 10 minutes of cooking.
5. Check the temperature
For the most reliable result, use an instant-read thermometer inserted into the center. Ground beef should reach 160°F.
6. Rest before slicing
Remove the meatloaf from the oven and let it rest for 10 minutes before slicing. This gives the juices time to settle and makes it easier to cut neat, substantial slices.

Pro Tips for Perfect Meatloaf
– Do not overmix the beef. Gently combine the ingredients just until incorporated for a more tender texture.
– Shred the cheese yourself when possible. Freshly shredded cheddar melts smoothly into the meat mixture.
– Keep the loaf evenly shaped. A consistent thickness helps it cook more evenly from edge to center.
– Use a thermometer. Cooking time can vary depending on the shape and thickness of the loaf, so 160°F in the center is the best doneness check.
– Let it rest. Those 10 minutes after baking make a noticeable difference when slicing.
– Add a simple glaze if desired. For a more traditional finish, spread ketchup or chili sauce over the top during the final 15 minutes of baking.
Easy Variations
Classic Ketchup Glaze
Spread a thin layer of ketchup over the loaf before the final 15 minutes of baking for a sweet, tangy, glossy topping.
Cheesy Blend
Replace some of the cheddar with Colby, Monterey Jack, or pepper jack while keeping the total cheese amount around 2 cups.
Extra Savory
Serve each slice with a spoonful of the flavorful pan juices for an even more comforting finish.

How to Store Leftover Meatloaf
Allow leftovers to cool, then refrigerate them in an airtight container. The slices make an excellent next-day lunch and can be reheated gently until warmed through.
For an easy leftover meal, place a slice on toasted bread and add ketchup, mustard, or mayonnaise. A little melted cheddar on top turns it into a hearty meatloaf sandwich.
Frequently Asked Questions
Can I prepare this meatloaf ahead of time?
Yes. Mix and shape the meatloaf up to one day ahead, cover it tightly, and refrigerate until you are ready to bake it.
Can I use another cheese?
Yes. Cheddar is ideal for its familiar flavor, but Colby, Monterey Jack, or pepper jack can also work well.
How do I know when meatloaf is done?
The safest and most reliable test is an instant-read thermometer. The center should reach 160°F.
Why should I let meatloaf rest before slicing?
Resting allows the juices to redistribute, helping the slices stay together and remain moist instead of falling apart immediately.
