How To Make Bacon Mushroom Swiss Meatloaf
- Prep The Aromatics
- Cook the bacon in a skillet over medium heat until crisp but not burnt, about 8 minutes. Remove and drain on paper towels, then crumble into small pieces. Pour off most bacon fat but leave about a tablespoon in the pan. Add chopped mushrooms and onions to the same pan, cooking until onions become translucent and mushrooms release their moisture, about 5 minutes. Set aside to cool completely before mixing with other ingredients.
- Preheat The Oven
- Set your oven to 375°F. This moderate temperature allows the meatloaf to cook through evenly without drying out the exterior. Position the rack in the middle of the oven for best heat distribution.
- Mix The Ingredients
- In a large bowl, combine ground beef, ground pork, cooled mushroom mixture, crumbled bacon, Swiss cheese, Parmesan cheese, breadcrumbs, and milk. Add eggs, Worcestershire sauce, tablespoon of ketchup, and all seasonings. Use clean hands to gently mix until just combined. Overmixing will make the meatloaf tough, so stop when ingredients are evenly distributed.
- Form The Loaf
- Transfer the mixture to a parchment lined baking sheet or loaf pan. Shape into a uniform loaf about 9 inches long and 5 inches wide. If using a baking sheet, the freeform loaf allows for more crust development. Spread the remaining ketchup evenly over the top of the meatloaf, covering completely.
- Bake To Perfection
- Place the meatloaf in the preheated oven and bake for 60 to 70 minutes. The internal temperature should reach 160°F when tested with a meat thermometer in the center. The top should be caramelized and slightly darkened around the edges.
- Rest Before Serving
- Allow the meatloaf to rest for 10 minutes before slicing. This crucial step allows the juices to redistribute throughout the meat and helps the loaf hold together when sliced. Use a sharp knife for clean slices.
The bacon in this recipe isn't just for flavor. I discovered through much testing that the fat from the bacon helps keep the entire meatloaf moist while adding that smoky depth that makes people come back for seconds. My father in law who claimed to hate meatloaf ate three slices the first time I served this and asked for the recipe.

Make Ahead Options
This meatloaf can be assembled up to 24 hours before baking. Simply prepare the mixture, shape the loaf, cover tightly with plastic wrap, and refrigerate. When ready to bake, remove from refrigerator, spread with ketchup, and allow to sit at room temperature for 20 minutes before baking. This actually improves the flavor as the ingredients have time to meld together.
Perfect Pairings
This hearty meatloaf pairs wonderfully with classic comfort sides. Creamy mashed potatoes make the ideal base, soaking up the flavorful meat juices. Roasted vegetables like Brussels sprouts or carrots provide a nice textural contrast. For a complete comfort meal, serve with buttered corn and a simple green salad dressed with vinaigrette to cut through the richness.
Troubleshooting Tips
If your meatloaf tends to crack on top, you likely need more binding ingredients. Add an extra egg or 1/4 cup more breadcrumbs to your next batch. For a meatloaf that falls apart when slicing, you probably didn't let it rest long enough. The 10 minute rest is non negotiable. If the bottom of your meatloaf turns out too greasy, try placing it on a rack inside your baking dish to elevate it above the drippings.
Creative Leftovers
Transform leftover meatloaf into entirely new meals. Slice it thin for the best sandwich of your life, especially on sourdough with extra Swiss cheese and dijon mustard. Crumble cold meatloaf into pasta sauce for an instant meat sauce that tastes like it simmered all day. Dice it up and use in morning hash with potatoes and a fried egg on top for a breakfast that will fuel you through lunch.

Recipe FAQs
- → Can I make this meatloaf ahead of time?
Yes! You can prepare the meatloaf mixture up to 24 hours ahead and keep it refrigerated. Shape it just before baking. You can also fully bake it, cool completely, then refrigerate for up to 3 days or freeze for up to 3 months.
- → What can I substitute for Swiss cheese?
If Swiss isn't available, try Gruyère for a similar nutty flavor, or provolone, mozzarella, or cheddar for different but delicious results. Each will create a slightly different flavor profile while maintaining the moist texture.
- → How do I know when the meatloaf is fully cooked?
The most reliable method is using a meat thermometer to ensure the internal temperature reaches 160°F (71°C). The meatloaf should also be firm to the touch, and any juices should run clear.
- → Can I use different types of ground meat?
Absolutely! While this uses beef and pork, you can substitute ground turkey, chicken, or veal. Just note that leaner meats might result in a slightly drier texture, so consider adding a bit more moisture with extra ketchup or even some grated zucchini.
- → What sides pair well with this meatloaf?
Classic pairings include mashed potatoes, roasted vegetables, green beans, or a simple salad. For a complete comfort food meal, serve with garlic mashed potatoes and glazed carrots.
- → Can I make this without mushrooms?
Yes, you can omit the mushrooms if needed. Consider substituting with finely diced bell peppers or zucchini to maintain moisture and add vegetables. Alternatively, simply increase the onion amount for flavor.
