5-Ingredient Sheet Pan Meatloaf
If you’re looking for an easy, comforting dinner that doesn’t require a long list of ingredients or a sink full of dishes, this 5-Ingredient Sheet Pan Meatloaf is a great choice. It’s simple enough for a busy weeknight, but still hearty and satisfying enough for a family dinner.
The meatloaf is tender and flavorful on the inside, while the ketchup topping becomes slightly caramelized and glossy as it bakes. Everything is prepared on one sheet pan, which makes cleanup much easier.
Ingredients
You only need five main ingredients:
- 1 pound (500 g) ground beef
- 1 large egg
- 1/2 cup breadcrumbs
- 1/2 cup ketchup, divided
- 1 packet dry onion soup mix
You can also use a small amount of cooking spray or oil to prevent sticking. Salt and black pepper are optional, but keep in mind that the onion soup mix and ketchup already contain seasoning.
Instructions
1. Preheat the oven
Preheat your oven to 375°F (190°C).
Line a large rimmed sheet pan with parchment paper or lightly grease it with cooking spray. Using parchment paper makes cleanup especially easy.
2. Prepare the meatloaf mixture
Add the ground beef, egg, breadcrumbs, dry onion soup mix, and 1/4 cup of the ketchup to a large mixing bowl.
Using clean hands or a wooden spoon, gently mix everything together until the ingredients are evenly combined.
Try not to overmix the meat. Mixing it too aggressively can make the finished meatloaf dense and tough. You only need to mix until you no longer see large pockets of breadcrumbs or seasoning.
3. Shape the meatloaf
Transfer the mixture to the prepared sheet pan.
Shape it into a compact loaf, approximately 2 inches thick. Try to keep the thickness relatively even so that the meatloaf cooks evenly from the center to the edges.
Avoid making the loaf extremely thick, because the outside can become overcooked before the center reaches a safe temperature.
4. Add the ketchup topping
Spread the remaining 1/4 cup ketchup evenly over the top of the meatloaf.
The ketchup will form a flavorful glaze as it cooks. It also helps the top develop a beautiful deep-red, slightly caramelized finish.
5. Bake
Place the sheet pan in the preheated oven.
Bake for approximately 40–50 minutes, depending on the thickness of the meatloaf and your oven.
The most reliable way to check doneness is with an instant-read thermometer. The center of the meatloaf should reach 160°F (71°C).
If the top starts browning too quickly, you can loosely cover it with aluminum foil for part of the remaining cooking time.
6. Let it rest
Once the meatloaf is fully cooked, remove it from the oven and let it rest for 5–10 minutes before slicing.
This short resting period helps the juices redistribute throughout the meat and makes the meatloaf easier to slice without falling apart.
7. Slice and serve
Use a sharp knife to cut the meatloaf into thick slices.
Serve immediately while warm with your favorite side dishes.
What to Serve with Sheet Pan Meatloaf

For an especially easy dinner, you can roast potatoes and vegetables on the same sheet pan. Just make sure you leave enough space around the meatloaf so everything can cook and brown properly.
Tips for Making the Best Meatloaf
Don’t overmix the meat
This is one of the most important tips. Once the ingredients are combined, stop mixing. Overworking ground beef can result in a firm, rubbery texture instead of a tender meatloaf.
Keep the loaf an even thickness
A meatloaf that is much thicker in the center will take longer to cook. Shaping it evenly helps everything cook at approximately the same rate.
Use enough breadcrumbs
Breadcrumbs help absorb moisture and give the meatloaf structure. They also help prevent the finished loaf from becoming overly dense.
Don’t skip the resting time
It can be tempting to slice the meatloaf immediately, especially when it smells amazing coming out of the oven. However, giving it a few minutes to rest makes a noticeable difference.
Check the internal temperature
Cooking time is only an estimate because ovens, pans, and loaf thicknesses vary. A thermometer is the easiest way to make sure the center is fully cooked.
Easy Variations
Although this recipe is designed around five basic ingredients, there are several ways to change it if you have extra ingredients available.
Add cheese
For a cheesy version, add shredded cheddar or mozzarella to the meat mixture. You can also place a little cheese in the center of the loaf before shaping it.
Add vegetables
Finely chopped onion, bell pepper, mushrooms, or grated carrot can be mixed into the meatloaf for extra flavor and texture.
Make the topping sweeter
Mix the ketchup with a small amount of brown sugar for a sweeter, more caramelized glaze.
Add a little spice
For a spicy version, add crushed red pepper flakes, hot sauce, or a little chili powder to the ketchup topping.
Use a different ground meat
You can replace some or all of the ground beef with ground turkey, chicken, or pork. Keep in mind that different meats can have different cooking times and textures, so always check the internal temperature.
How to Store Leftovers
Allow leftover meatloaf to cool before transferring it to an airtight container.
Store it in the refrigerator and use it within 3–4 days.
You can reheat individual slices in the microwave, oven, or skillet. Adding a little ketchup or another sauce before reheating can help keep the slices moist.
How to Freeze Meatloaf
Meatloaf also freezes well.
For easy portions, slice the cooled meatloaf and wrap the individual slices before placing them in a freezer-safe container or bag.
When you’re ready to eat them, thaw the slices in the refrigerator and reheat until hot throughout.
Frequently Asked Questions
Can I make this meatloaf ahead of time?
Yes. You can prepare the meat mixture, shape the loaf, cover it, and refrigerate it until you’re ready to bake. This makes it a convenient option for meal prep or busy evenings.
Can I use fresh onion instead of onion soup mix?
Yes, but it will change the recipe slightly. The dry onion soup mix provides both onion flavor and seasoning, so if you replace it with fresh onion, you may want to add additional seasonings.
Why is my meatloaf falling apart?
This can happen if the mixture doesn’t have enough binder, if it was not mixed sufficiently to combine the ingredients, or if it was sliced immediately after baking. Letting it rest before slicing can help considerably.
Can I make smaller meatloaves?
Absolutely. You can divide the mixture into two smaller loaves. Smaller loaves will generally cook faster, so start checking the internal temperature earlier.
Can I make this recipe gluten-free?
Yes, provided you use gluten-free breadcrumbs and a gluten-free onion soup mix. Check the packaging of the specific products you use.
