Slow-Cooker Mushroom Meatloaf

Published on January 20, 2017 by Raveaboutfood

Slow-Cooker Mushroom Meatloaf is a new twist on an old classic. Portabella mushrooms make this meatloaf rich and earthy. Cooking it in the slow-cooker makes it moist and juicy. Add a sweet, tangy glaze to the top for a hearty meal that is soon to be a regular in your recipe rotation!

Raise your hand if you have always made meatloaf in the oven? Yep, me too! Well, not anymore. I’m convinced using the slow-cooker is another great way to make meatloaf that is flavorful and juicy. And remember to line the slow-cooker so that clean up is a breeze.

Slow-Cooker Mushroom Meatloaf Recipe

What’s needed?

  • 1 small onion, chopped
  • 1 8-ounce package Portabella mushrooms, chopped finely
  • 1 teaspoon minced garlic
  • 1 cup Italian bread crumbs
  • 1 egg
  • 1/3 cup milk
  • 1 teaspoon each salt and pepper
  • 1 1/2 pound ground beef
  • 1/3 cup ketchup
  • 1 tablespoon mustard (regular or Dijon)
  • 1 tablespoon light brown sugar

How to make Mushroom Meatloaf?

  • Line the slow cooker with two long strips of aluminum foil. Place one lengthwise and press into the slow cooker. Place the other piece of foil across the slow cooker sideways, so all sides are covered.
  • Chop the onion and the mushrooms and put them in a bowl. I used the food processor to finely chop them.
  • Put the chopped mushroom mixture in a large bowl and add the garlic, bread crumbs, egg, milk, salt and pepper. Mix until well combined.
  • Add the ground beef and mix thoroughly. Using your hands is the easiest way to mix it well.
  • Form the beef mixture into a loaf and place it into the slow cooker.

  • Use the foil strips to lift the meatloaf out of the slow cooker. Remove it from the foil and place it on a platter for serving. Clean up is easy, no need to wash the slow cooker, just throw the foil away.

Serve the meatloaf with your favorite sides. We had mashed potatoes with mushroom gravy and asparagus. If you like mushrooms, you are going to love this version of Mushroom Meatloaf.
