Elevate your burger game with this mouthwatering Patty Melt, combining succulent beef patties, sugary soft onions and gooey Swiss cheese, all sandwiched between crispy rye bread slices. This tasty creation blends a hamburger and grilled cheese into something you won't be able to put down.
Whenever I make this, I think back to the small-town diner I went to as a kid, where I'd sit at the counter watching cooks flip these beauties on their seasoned griddle. I've spent ages getting it just right at home, and the smell of those slowly cooking onions always brings those memories flooding back.
Key Ingredients Breakdown
- Ground Chuck: Go for 80/20 meat for just the right amount of fat. Grab it freshly ground for the tastiest results.
- Rye Bread: Try to find thick, bakery-fresh slices that won't fall apart with all the fillings.
- Swiss Cheese: Grate it yourself instead of buying pre-shredded for smoother melting.
- Yellow Onions: Pick ones that feel heavy and don't have any mushy parts.
- Unsalted Butter: The fancy European kind will give you a nicer golden finish.
Step-By-Step Cooking Guide
- Step 1: Getting Those Onions Just Right
- Cut onions the same size so they cook evenly. Don't rush them on low heat. Only stir now and then to build color. They should turn a rich golden brown. Scrape up all the tasty bits from the pan.
- Step 2: Making Your Burger Patties
- Don't overwork the meat or it'll get tough. Make the sides a bit thicker than the middle. Add salt and pepper right before cooking. Let them cook without poking at them. Don't smash them with your spatula.
- Step 3: Putting It All Together
- Get your bread lightly golden but not burnt. Put cheese right against the bread so it melts properly. Spread onions all over. Lightly press everything together when you're done.

My dad always told me that taking your time with the onions was the secret to an amazing patty melt. After making tons of these sandwiches, I can tell you he wasn't wrong. Those slow-cooked onions turn a basic sandwich into something you'll crave again and again.
What makes this so good is how straightforward it is. Every part plays an important job, and when you take care with each step, you end up with something truly special.
I've found that good bread can totally change this sandwich. A nice rye has a slight sourness that works so well with those sweet onions.

Even though I've made countless patty melts over the years, this version still makes me happy every time. The mix of well-seasoned beef, sweet onions, and toasty rye creates something that's both cozy and a bit fancy at the same time.
