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. Adding a sweet, tangy glaze to the top makes 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 with aluminum foil, so that you can easily lift the meatloaf out of the slow cooker, making clean up quick and easy.
How to make Mushroom Gravy?
The juices that have accumulated in the bottom of the slow cooker can easily be turned into a mushroom gravy to serve with the meatloaf. The gravy adds so much flavor to the meatloaf and can be poured over creamy mashed potatoes.
Simply transfer the liquid from the slow cooker to a skillet over medium-high heat. Bring it to a boil and whisk in two tablespoon of flour until smooth. Add one cup of milk and continue stirring for about 5 minutes until thick. Add salt and ground black pepper to taste. Reduce heat to medium-low. Gravy is ready when it has become thick and smooth.
What to serve with Mushroom Meatloaf?

How to make Mushroom Meatloaf?
Step-by-Step Instructions:
- 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.
- Mix together the ketchup, mustard and brown sugar in a small bowl. Pour the mixture over the meatloaf and spread evenly to cover.
- Put the lid on the slow cooker and cook on high for 3 1/2 hours.
- 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 side dishes. We had loaded mashed potatoes and mushroom gravy over the meatloaf. If you like mushrooms, you are going to love Slow-Cooker Mushroom Meatloaf.
