This Mushroom Swiss Cheese Meatloaf delivers the ultimate in comfort food thanks to juicy ground beef, plenty of sautéed mushrooms, and a generous filling of melty Swiss cheese. Every slice is loaded with savory flavor, just the way my family enjoys it on cozy winter evenings.
The first time I made this, the Swiss cheese melted into gooey pockets and my kids begged for it again before we even finished dinner.
Ingredients
- Ground beef: provides richness and structure to the meatloaf so aim for eighty percent lean for the best balance of flavor
- Ground pork: delivers juiciness and a subtle sweetness that rounds out the beef so choose fresh pork for the best taste
- Breadcrumbs: absorb moisture and help hold the loaf together use fresh or dried but make sure they are not stale
- Milk: guarantees a tender texture and prevents the loaf from drying out whole milk is best
- Grated Parmesan cheese: adds a nutty bold flavor select a block and grate it yourself for the freshest results
- Finely chopped onions: introduce sweetness and depth dice very small for even flavor
- Finely chopped mushrooms: give earthy richness and keep the meatloaf moist use cremini or button mushrooms
- Cooked bacon: supplies smoky savoriness make sure it is crisp and well drained
- Shredded Swiss cheese: is the star for a creamy stretchy center buy it fresh and shred at home for best melt
- Large eggs: work as binders so pick fresh eggs for best texture
- Worcestershire sauce: deepens the umami flavor so find one with a rich aroma
- Ketchup: lends tangy zip and moisture to the mix opt for a high quality brand
- Garlic powder and dried thyme: round out the savory flavors pick dried herbs that smell fragrant and fresh

Step-by-Step Instructions
- Preheat the Oven:
- Set your oven to three hundred seventy five degrees Fahrenheit or one hundred ninety degrees Celsius so the meatloaf bakes evenly from the start
- Prepare the Ingredients:
- Cook the bacon in a skillet until it is very crispy then crumble it into little pieces In the same pan sauté onions and mushrooms over medium heat until mushrooms are tender and onions look translucent Set aside to cool
- Mix the Meatloaf:
- In your largest mixing bowl combine the ground beef ground pork breadcrumbs milk Parmesan cheese bacon Swiss cheese onions and mushrooms Crack in the eggs Pour in Worcestershire sauce and one tablespoon of ketchup Sprinkle in garlic powder thyme salt and pepper Gently mix everything with clean hands or a sturdy spoon until just combined For best texture do not overmix
- Shape and Add Topping:
- On a lined baking sheet or in a baking dish shape the mixture into a loaf about two inches high Smooth it gently so it does not crack Spread the remaining ketchup evenly over the top to lock in moisture
- Bake Until Done:
- Slide the pan into the oven and bake for sixty to seventy minutes The loaf should be deeply browned and the internal temperature must read one hundred sixty degrees Fahrenheit or seventy one degrees Celsius when checked in the center
- Rest and Serve:
- Remove meatloaf from the oven and let it rest for ten minutes before slicing This lets the juices settle and keeps every portion moist Serve while warm and enjoy

I always look forward to that little stretch of melted Swiss cheese in every bite For years my brother would try to sneak the cheesy center pieces before the rest of us could get to them and now we make two loaves to keep everyone happy
Storage Tips
Keep leftover meatloaf tightly wrapped in foil or in an airtight container for up to four days in the refrigerator For longer storage slice and freeze individual pieces wrapped in parchment for up to two months Simply reheat portions in the oven for best taste
Ingredient Substitutions
