Recipe: Instant Pot Meatloaf and Mashed Potatoes (2)

Have you discovered pot-in-pot Instant Pot cooking yet? The technique, which allows you to make two distinct dishes in your Instant Pot in just one round of cooking, is especially revolutionary for weeknight dinners.

My favorite of these pot-in-pot recipes is meatloaf and mashed potatoes. The potatoes are boiled to tenderness in the bottom of the pot, while homey meatloaf is cooked in a cake pan set atop the Instant Pot’s trivet. With pot-in-pot cooking, you can have homemade meatloaf and mashed potatoes in under an hour. Here’s how to do it.

What Is Pot-In-Pot Cooking?

Pot-in-pot cooking is a simple way to create layers within your electric pressure cooker’s insert. You’ll use a trivet (the one that came with your Instant Pot is ideal) to elevate a pan over another dish cooking in the Instant Pot at the same time. Cake pans or disposable aluminum pans are the most popular “pots” for pot-in-pot cooking.

Perhaps the most crucial step in pot-in-pot cooking is ensuring that once you set your pan inside your pot, there is enough room around it for steam to move freely and help build pressure. A six-inch cake pan is idea for this endeavor because it easily slides in and out of the Instant Pot.

It’s also helpful to create a sling for your pan, which makes it easier to remove from the hot Instant Pot. You can buy a silicone version or make a simple aluminum foil one for a single use.

Instant Pot Meatloaf and Mashed Potatoes

This is a pretty basic — albeit delicious — meatloaf and mashed potatoes adapted to the Instant Pot (meaning there are no special ingredients exclusive to this method). However, it’s important that you cook the potatoes in water, rather than broth or milk, which prevents receiving a “burn” message from your pot and ensures the pot reaches pressure.

As for getting a gorgeous glaze on you meatloaf, don’t attempt this in the Instant Pot! There’s too much steam and quite a bit of fat rendering off the meatloaf while it cooks. Instead, move the cooked meatloaf to the oven to achieve a glossy finish. This will give you just enough time to finish the potatoes anyway.

Nutritional Info

Ingredients

For the meatloaf

  • 2 pounds

    lean ground beef

  • 1/2 cups

    panko breadcrumbs

  • 1/3 cup

    whole milk

  • 1

    small yellow onion, grated on the large holes of a box grater

  • 1

    large egg, lightly beaten

  • 1 teaspoon

    kosher salt

  • 1/4 cup

    ketchup

  • 2 tablespoons

    packed ight brown sugar

  • 2 tablespoons

    Dijon mustard

  • 2 pounds

    large Yukon gold potatoes, peeled and quartered

  • 2 cups

    water

  • 1/2 teaspoon

    kosher salt

  • 1 cup

    half-and-half

  • 4 tablespoons

    unsalted butter

Instructions

  1. Place the ground beef, breadcrumbs, milk, onion, egg, and salt in a large bowl. Use your hands to gently combine until hom*ogeneous. Shape the meat mixture into a loaf, about 6 inches long and 4 inches wide, and set inside a 6-inch round cake pan; set aside.

  2. Combine the potatoes, water, and salt in the Instant Pot insert and stir to combine. Place a trivet over the potatoes.

  3. Create a sling for the meatloaf pan by folding a 12-inch long piece of aluminum foil lengthwise into a 3-inch wide strip. Place the meatloaf pan in the center of the strip and then fold up the sides — you should have 3 to 4 inches of overhang (handles) on either side.

  4. Lower the meatloaf pan into the Instant Pot and place on top of the trivet. Seal the Instant Pot and set to MANUAL pressure on HIGH for 35 minutes. While the meatloaf cooks, arrange a rack in the middle of the oven and heat to 400°F. Stir the ketchup, brown sugar, and mustard together in a small bowl to make the glaze.

  5. When the cook time is over, let the Instant Pot naturally release pressure for 10 minutes. Manually release any remaining pressure. Open the Instant Pot and use the foil sling to carefully remove the meatloaf — there will be quite a bit of fat and juices around the meatloaf, don’t worry if any of this drips into the potatoes. Carefully drain off the fat and juices around the meatloaf. Brush the meatloaf with the glaze and bake until it is glossy and caramelized, 8 to 10 minutes.

  6. While the meatloaf bakes, add the half-and-half and butter to the potatoes and mash to desired consistency. Slice the meatloaf and serve with the mashed potatoes.

FAQs

Why not cook meatloaf in the loaf pan? ›

By free-forming a meatloaf—not cooking it in a loaf pan—we get maximum surface area exposure, and therefore maximum flavor. So not only does it make it easier to slice and guard against sogginess, but mounding your meatloaf instead of panning it also makes your meatloaf literally tastier.

Why milk instead of water in meatloaf? ›

Milk and other dairy products, like heavy cream and buttermilk, contain both water and fat, adding two types of moisture to our meatloaf. There's a long-held theory that milk can tenderize ground meat, and this is the reason often cited for cooking ground meat in milk to make a Bolognese-style ragù.

Why do you put baking soda in meatloaf? ›

Adding baking soda to the beef keeps it moist by stopping the proteins from binding too quickly (which dries out the meat). Using sauteed onions instead of raw ensures the onions don't turn out crunchy and adds extra moisture to the meatloaf. Moistened breadcrumbs, keep the meatloaf moist and tender.

How long do meatloaf and mashed potatoes last in the fridge? ›

For leftovers, the same 3 to 4 days guideline applies. Be sure to refrigerate the meatloaf within two hours of cooking to prevent bacteria growth. Recognizing signs of spoilage is crucial to avoid consuming food that may make you sick.

Should I cook my meatloaf covered or uncovered? ›

Should I cook my meatloaf covered or uncovered? The meatloaf can be cooked uncovered. However, if you are concerned about it burning, you can cover the meatloaf with foil for the first 45 minutes and uncover it for the final 15 minutes to allow the meatloaf to brown on top.

Why does my meatloaf fall apart when I cook it? ›

When this happens, it's because you didn't use enough. Next time, try adding in an extra egg and/or some more breadcrumbs.

What is the secret to a great meat loaf? ›

Use high-fat meat.

For a meatloaf made with a leaner beef or turkey, consider mixing in some ground pork and/or veal in order to achieve a moist, tender meatloaf. Chopping up bacon and adding it to the mix is always a great way to add fat. Oh, and covering it in bacon never hurts, either.

What does adding an extra egg to meatloaf do? ›

Sure, egg yolks add some rich flavor to a meatloaf, but the real reason we need eggs is for structure—to help bind the meatloaf together. This is especially important since we're making a free-form meatloaf, or one that you shape by hand, versus using a loaf pan.

What is the basic meatloaf formula? ›

The Basic Meatloaf Formula

All recipes for meatloaf start with the same basic formula: 2 pounds of ground meat and a “panade” made of bread or crackers soaked in milk. Along with a few eggs, this panade helps to hold the ground meat together and adds some essential moisture to the mix.

Should I saute onions before adding to meatloaf? ›

I later learned how I could avoid this problem and make a fully smooth meatloaf by pre-cooking any vegetables, especially the onion, before adding them to the ground meat. This way the meatloaf gets the flavor without the rawness -- a method from the smart people at Cook's Illustrated.

Are you supposed to drain the grease from meatloaf? ›

To prevent a soggy bottom, Bangor Daily News suggests draining the grease from the loaf pan 15 minutes before your cooking time is up; this helps guarantee all sides bake to perfection.

What is the secret ingredient to tenderize meat? ›

Whether hosting a holiday cookout, serving up some stir-fry or tackling game meats, baking soda is the go-to meat tenderizer to help make your steak, chicken or turkey silkier, juicier and yummier.

Can you eat 5 day old mashed potatoes? ›

How Long You Can Keep Leftover Mashed Potatoes. Mashed potatoes should easily last three to five days in the fridge if stored correctly and within two hours of cooking. This means ensuring there isn't any moisture buildup under the lid that could encourage the growth of bacteria.

Can you eat 5 day old meatloaf? ›

If you don't think you will eat your meatloaf within 3-4 days, consider freezing it for prolonged storage. You can freeze meatloaf for several months without it spoiling.

Can you eat mashed potatoes after sitting out all night? ›

Mashed potatoes can sit out for two hours at room temperature. Any longer than that, they can enter the “danger zone,” which are unsafe temperatures that promote the growth of bacteria. If temperatures go above 90 °F, mashed potatoes can only sit out for one hour.

Is a sheet pan better than a loaf pan for meatloaf? ›

When choosing a baking pan, avoid a small loaf pan or baking dish. A tight fit means that the loaf will steam — think school cafeteria meatloaf. Instead, use a sheet pan or a large baking dish and leave some breathing room so the edges will caramelize nicely.

What is the best pan to cook meatloaf in? ›

Loaf pans corral the juices and fat to create a moister, more steamed, texture. The steamed texture can often be more reminiscent of a school cafeteria meatloaf, which some people are averse to, but it will look more like a typical meatloaf when it's cooked this way as meatloaf in a sheet pan tends to be flatter.

How do you keep meatloaf from sticking to the loaf pan? ›

Lining your loaf pan with parchment paper creates a nonstick surface that makes it easy to get the meatloaf out of the pan when it's done.

Do you need to grease a loaf pan for meatloaf? ›

Here's a simple trick to reduce the grease in your homemade meatloaf. When making meat loaf, line the bottom of your pan with slices of bread. Place the meat mixture in the pan and bake as usual. The bread will absorb most of the fat from the meat as it cooks.
