I love how this Mushroom Swiss Patty Melt brings together everything I crave in a comfort sandwich. It is warm, cheesy, savory, and perfectly crisp on the outside while staying juicy and flavorful inside. Whenever I want something cozy and filling that feels like diner food made at home, this is what I make.
Why You’ll Love This Recipe
I enjoy this recipe because it is simple, satisfying, and packed with flavor. I like how the caramelized onions and mushrooms add sweetness and depth, while the Swiss cheese melts beautifully over the beef patty. It is also a great option when I want a quick stovetop meal that feels special without being complicated.
Ingredients
(Tip: You’ll find the full list of Ingredients and measurements in the recipe card below.)
1 lb ground beef
Salt and black pepper, to taste
1 small onion, thinly sliced
8 oz mushrooms, sliced
2 tbsp butter
1 tbsp oil
4 slices Swiss cheese
4 slices rye or sandwich bread
Directions
I start by seasoning the ground beef with salt and black pepper, then I shape it into two thin, oval-shaped patties that fit the bread nicely. I heat a skillet over medium heat and cook the patties until they are browned on both sides and cooked through, then I remove them from the pan and set them aside.
In the same skillet, I add the butter and oil. I put in the sliced onions and mushrooms and cook them slowly, stirring often, until they are soft, golden, and nicely caramelized. This usually takes about 8 to 10 minutes.
I lower the heat and return the beef patties to the skillet. I place Swiss cheese on top of each patty and let it melt slightly. I then assemble the sandwiches by placing a cheesy patty and a generous spoonful of the mushroom-onion mixture between two slices of bread.
I wipe out the skillet if needed, then lightly butter the outside of each sandwich. I grill them over medium heat, flipping once, until the bread is golden brown and crisp and the cheese is fully melted inside.
Servings And Timing
I usually make this recipe to serve 2 people.
Prep time is about 10 minutes.
Cook time is about 20 minutes.
Total time comes to roughly 30 minutes.
Variations
I sometimes swap the ground beef for ground turkey when I want a lighter option. When I feel like changing up the flavor, I use provolone or mozzarella instead of Swiss cheese. I also like adding a little garlic or a splash of Worcestershire sauce to the mushrooms for extra depth.
Storage/Reheating
I store leftover patty melts wrapped tightly in foil or in an airtight container in the refrigerator for up to 2 days. When reheating, I prefer using a skillet over low heat so the bread stays crisp and the inside warms evenly. I avoid the microwave when possible because it can make the bread soggy.
FAQs
Can I make this ahead of time?
I can prepare the patties and the mushroom-onion mixture ahead of time and store them separately, then assemble and grill the sandwiches when I am ready to eat.
What bread works best for a patty melt?
I like using rye bread, but any sturdy sandwich bread works well as long as it can hold up to grilling.
How do I keep the patties juicy?
I make sure not to overcook the beef and I keep the patties thin so they cook quickly and evenly.
Can I add sauce to this sandwich?
I sometimes add a thin layer of mayonnaise or a bit of mustard inside the sandwich for extra flavor.
Are mushrooms required?
I personally love the mushrooms, but I can leave them out or replace them with extra onions if needed.
