The Best Ground Beef for Meatloaf

This is super important.

For juicy meatloaf, use 80/20 ground beef.

That little bit of extra fat keeps everything moist and flavorful while baking. Super lean ground beef sounds healthier, but it can make meatloaf dry and crumbly.

And nobody wants sad dry meatloaf.

How to Make Meatloaf With Oatmeal

Step-by-Step Instructions

1. Preheat the Oven

Set your oven to 350°F.

Lightly grease a loaf pan or line a baking sheet with parchment paper if you prefer a freeform loaf.

2. Mix the Meatloaf Ingredients

In a large bowl, combine:

• Ground beef
• Quick oats
• Onion
• Milk
• Eggs
• Worcestershire sauce
• Salt
• Pepper
• Garlic powder
• Onion powder

Use your hands to gently mix everything together.

Do not overmix. That’s one of the biggest reasons meatloaf turns tough.

3. Shape the Meatloaf

Transfer the mixture into a loaf pan and smooth the top.

If using a baking sheet, shape the mixture into a loaf shape by hand.

4. Make the Glaze

In a small bowl, stir together:

• Ketchup
• Brown sugar
• Mustard

Spread half the glaze over the top of the meatloaf.

5. Bake the Meatloaf

Bake uncovered for about 1 hour.

Carefully drain excess grease if needed.

Spread the remaining glaze on top and bake another 10 minutes, or until the internal temperature reaches 160°F.

6. Let It Rest

This part matters more than people realize.

Let the meatloaf rest for 15 minutes before slicing so the juices stay inside and the slices hold together better.

Tips for the Best Meatloaf With Oatmeal

Use 80/20 Ground Beef

A little fat keeps the meatloaf juicy and flavorful.

Finely Chop the Onion

Large onion chunks can make the meatloaf fall apart.

Don’t Skip the Glaze

That sweet tangy topping adds so much flavor and gives the meatloaf that classic homemade look.

Avoid Overbaking

Overcooked meatloaf dries out quickly.

Use a meat thermometer if possible.

How to Keep Meatloaf From Falling Apart

Nothing is more heartbreaking than slicing meatloaf and watching it collapse into chaos.

Here’s how to avoid that:

• Use enough binder ingredients like oats and eggs
• Don’t add too many vegetables
• Avoid overmixing
• Let it rest before slicing
• Don’t overcook it

This recipe has the perfect balance, so it holds together nicely while still staying tender.

Easy Variations to Try

One of the fun things about meatloaf is how customizable it is.

Add Cheese

Mix shredded cheddar into the meat mixture for extra comfort-food vibes.

Honestly, melted cheese makes almost everything better.

Add Herbs

Parsley, oregano, or Italian seasoning work beautifully here.

Use BBQ Sauce Instead of Ketchup

For a smoky twist, swap the ketchup glaze for barbecue sauce.

Add Garlic

Fresh minced garlic gives the meatloaf extra flavor depth.

Swap the Protein

Ground turkey works too, though it’ll be slightly less rich than beef. If you want a lighter version that still stays juicy and flavorful, this cozy turkey meatloaf recipe is another easy family dinner option worth trying.

So good.

How to Store Leftovers

This meatloaf stores incredibly well.

Refrigerator

Store slices in an airtight container for up to 4 days.

Freezer

Wrap slices individually and freeze for up to 3 months.

I actually love freezing individual portions because it makes easy lunches later.

How to Reheat Meatloaf

The microwave works fine, but the oven gives the best texture.

Oven Method

Place slices in a baking dish with a splash of water or broth. Cover with foil and bake at 325°F until heated through.

Microwave Method

Heat in 30-second intervals until warm.

Easy.

The Secret to Amazing Meatloaf Sandwiches

Okay, this might actually be my favorite part.

Cold leftover meatloaf on toasted bread with mayo and extra ketchup is ridiculously good.

Add cheese if you want to make it extra cozy.

I’ve definitely made this for midnight snacks before and I’m not even sorry about it.

Common Meatloaf Mistakes

Using Lean Beef

This leads to dry meatloaf fast.

Overbaking

Too much oven time dries everything out.

Skipping the Rest Time

This causes crumbly slices.

Using Steel-Cut Oats

Please don’t do this. Your meatloaf will end up weirdly chewy.

Quick oats are the move.
