This Instant Pot Meatloaf and Mashed Potatoes recipe is a complete comfort food meal made entirely in the instant pot! It takes just 20 minutes to prep and the result is moist, flavorful meatloaf and smooth, creamy mashed potatoes.
– Breadcrumbs: use seasoned breadcrumbs for easy flavor. You can use plain breadcrumbs but you will likely need to add more seasonings yourself. – Milk: soaks into the breadcrumbs to add tons of moisture. – Ground Beef and Ground Pork: I recommend using lean ground beef and pork so the meatloaf isn’t overly oily. The moisture in the instant pot prevents the lean meat from drying out anyway! – Parmesan Cheese: adds salty, cheesy flavor and additional moisture. – Eggs: binds the meatloaf together so it can hold its shape. – Italian Seasoning, Salt, Onion Powder, and Black Pepper: a simple blend of seasonings that gives the meatloaf so much flavor.
Combine meatloaf ingredients: In a medium bowl, stir together breadcrumbs and milk, then set aside. In a separate large bowl, combine beef, pork, cheese, eggs, Italian seasoning, salt, onion powder, and pepper. Add in the soaked breadcrumbs and mix until the breadcrumbs are incorporated.
Prep the potatoes: Cut the potatoes into 1 1/2-2″ chunks and place into the bottom of the instant pot. Add in the chicken broth.
Prep the meatloaf: Shape the meatloaf into a circle (so that it will fit into your pressure cooker with some room on the sides), then set onto a large piece of tin foil. Wrap the foil up around the sides of the meatloaf but not over the top. Place the foil covered meatloaf on top of the potatoes.
Cook: Place the lid on the instant pot, select Manual or Pressure Cook, and cook at high pressure for 30 minutes.
Make the glaze: Stir together the ketchup, sugar, and vinegar, then microwave for 20-30 seconds so the sugar can dissolve (optional.) Finish the meatloaf: When the cook time is up, let the pressure release naturally for 8-10 minutes, then open the valve and remove the lid. Remove the meatloaf, brush the glaze over the top, then cover and let rest.
Mash the potatoes: To the potatoes in the instant pot, add the milk, butter, salt, pepper, and garlic powder. Mash to desired smoothness, adding milk or butter if necessary. Taste and adjust the seasonings if needed.
