These Meatloaf Sliders are mini sandwiches packed with flavor! Each bite combines juicy meat, savory spices, and a touch of sweetness from the ketchup. Yum!
They’re perfect for a fun gathering or just a cozy night in. I love serving them with crispy fries on the side—just makes sense, right? 🍔
Key Ingredients & Substitutions
Ground Beef: I usually go for 80% lean ground beef because it keeps the sliders juicy. You can substitute with ground turkey or chicken for a leaner option, but it may change the texture a bit. Adding a little extra moisture can help!
Breadcrumbs: Traditional breadcrumbs work great, but you can use panko for a crunchier texture. If you’re gluten-free, try crushed cornflakes or gluten-free breadcrumbs. I’ve even used oats in a pinch!
Onion and Garlic: Fresh is best for flavor, but if you’re short on time, onion powder and garlic powder can do the trick. Quick tip: soak dried onion in water for a few minutes, and it’ll soften nicely!
Ketchup: Ketchup adds moisture and sweetness. You can swap it with BBQ sauce for a smokier flavor. Mix in some hot sauce if you want a kick! Personally, I like a mix of ketchup and a bit of Sriracha.
Cheese: While mozzarella or provolone are my favorites, cheddar melts beautifully too! Feel free to swap with what you have; pepper jack adds nice heat as well.
How Do I Ensure My Meatloaf Sliders Are Cooked Just Right?
Getting the right cook on your meatloaf sliders can be tricky! Here’s how to do it:
- Always check the internal temperature with a meat thermometer. Aim for 160°F (71°C).
- Avoid overmixing the meat mixture to keep it tender. Just mix until combined!
- Shape your patties evenly so they’ll cook uniformly. If some are thicker, they’ll take longer to cook.
- Cooking time may vary based on your oven, so keep an eye on them.
By following these steps, you’ll get perfectly delicious sliders every time!

How to Make Meatloaf Sliders
Ingredients You’ll Need:
For the Sliders:
- 1 lb ground beef (80% lean)
- 1/2 cup breadcrumbs
- 1/4 cup milk
- 1/4 cup finely diced onion
- 1 clove garlic, minced
- 1 large egg
- 1 tbsp Worcestershire sauce
- 1 tsp salt
- 1/2 tsp black pepper
- 1/2 cup ketchup (plus extra for topping)
- 4 slider buns, soft and slightly sweet
- 4 slices mozzarella or provolone cheese (optional)
- Butter (for buns, optional)
- Lettuce or spinach leaves (optional)
How Much Time Will You Need?
This recipe will take about 30 minutes in total! You’ll spend about 10 minutes prepping the ingredients and shaping the patties, followed by 20-25 minutes baking them in the oven. If you choose to toast the buns, you may add an extra 5 minutes, but it’s totally optional!
Step-by-Step Instructions:
1. Preheat the Oven:
Start off by preheating your oven to 375°F (190°C). This will get it nice and hot while you prepare the sliders. No one likes waiting around for their food!
2. Mix the Meat Mixture:
In a large bowl, mix together your ground beef, breadcrumbs, milk, diced onion, minced garlic, egg, Worcestershire sauce, salt, black pepper, and 1/2 cup of ketchup. Use your hands or a spoon to combine everything gently, but be careful not to overwork the meat; just mix until everything is evenly distributed.
3. Shape the Patties:
Take a handful of the meat mixture and shape it into small oblong patties. Make sure they fit well inside your slider buns. About the size of your palm should do—just remember they will shrink slightly while cooking!
4. Prepare for Baking:
Place the patties on a baking sheet lined with parchment paper or lightly greased to prevent sticking. Give them a little space between each patty for even cooking.
5. Bake the Sliders:
Pop the baking sheet into your preheated oven and bake for about 20-25 minutes. Check for doneness by ensuring the internal temperature reaches 160°F (71°C). You’ll know they are deliciously cooked through!
6. Add the Cheese:
When the sliders are almost done, take them out of the oven, and place a slice of cheese on top of each patty. Return them to the oven for a few more minutes, just until the cheese melts perfectly.
7. Toast the Buns (Optional):
If you’d like to toast your slider buns, go ahead! Lightly butter the insides and place them in a skillet or oven until they are golden brown. This adds an extra touch of flavor and crunch!
8. Assemble the Sliders:
Spread a bit of extra ketchup on the bottom halves of each bun. Then place a meatloaf slider patty on top, followed by lettuce or spinach leaves if you’re using them. Cover with the top bun for that perfect mini sandwich.
9. Serve and Enjoy:
For added fun, secure each slider with a toothpick. Serve warm and enjoy these hearty, flavorful sliders at your next gathering or cozy night in!
These meatloaf sliders are easy to make and super satisfying—they’re sure to be a hit with the whole family!
Can I Use Ground Turkey or Chicken Instead of Beef?
Absolutely! Ground turkey or chicken works well for a leaner option. Just keep in mind that you may need to adjust the cooking time slightly, as poultry can cook faster. Always check that the internal temperature reaches 165°F (74°C).
What Can I Use Instead of Breadcrumbs?
If you don’t have breadcrumbs, crushed crackers, panko, or even rolled oats can be great substitutes. For a gluten-free option, use gluten-free breadcrumbs or crushed cornflakes to maintain texture!
How Do I Store Leftover Sliders?
Store any leftover sliders in an airtight container in the fridge for up to 3 days. When reheating, you can use the microwave or oven to warm them back up. If you’d like, add a splash of ketchup to revive the flavor!
Can I Make the Patties Ahead of Time?
Yes, you can! Shape the patties and refrigerate them for up to 24 hours before baking. Just remember to let them come to room temperature for about 15 minutes before putting them in the oven for even cooking!
