Grilled Patty Melt

Category: Easy Sandwiches Done Right

This sandwich is a crowd-pleaser thanks to a few key elements. First, onions are slowly softened and sweetened for 30+ minutes, with a splash of vinegar for depth. The beef patties, made with 80/20 ground chuck, are seared till crusty on the outside but stay moist inside. Rye bread is slathered with butter for that perfect golden crunch on both sides when grilled. Melted Swiss cheese ties it all together for a satisfying bite every time—crispy bread, juicy beef, tender onions, and rich cheese in perfect harmony.

Elevate your burger game with this mouthwatering Patty Melt, combining succulent beef patties, sweet slow-cooked onions and gooey Swiss cheese, all sandwiched between crispy rye bread slices. This delightful creation merges the comfort of grilled cheese with the satisfaction of a hamburger in one amazing handheld treat.

Whenever I whip up this sandwich, I'm taken back to the neighborhood diner from my youth where I'd sit mesmerized watching the cooks flip these beauties on their seasoned griddle. I've spent years getting my home version just right, and the smell of those slowly browning onions still triggers those wonderful old memories.

Key Ingredients Breakdown

  • Ground Chuck: Go for 80/20 meat for ideal juiciness. Newly ground gives superior taste.
  • Rye Bread: Pick substantial, bakery-fresh slices that won't fall apart.
  • Swiss Cheese: Grate it yourself for smoother melting compared to store-bought shreds.
  • Yellow Onions: Choose ones that feel weighty and don't have any mushy areas.
  • Unsalted Butter: Fancy European varieties will give you nicer browning.

Step-By-Step Guidance

Step 3: Assembly Mastery
Brown your bread to golden perfection without burning. Put cheese right against the bread so it melts properly. Spread onions in an even layer. Apply gentle pressure when putting it all together.
Step 1: Perfecting Caramelized Onions
Cut onions the same size for consistent cooking. Use gentle heat without rushing. Don't stir too much so color can develop. They're done when they turn rich amber brown. Add a splash of liquid to scrape up all the tasty bits.
Step 2: Creating the Perfect Patty
Work the beef as little as possible for tenderness. Make the outer edge thicker than the middle. Add salt and pepper just before it hits the pan. Don't move it while it's cooking. Avoid squashing it with your spatula.

My dad always told me that taking your time with the onions was the secret to an amazing patty melt. Now that I've made hundreds of these, I totally get it. Those slow-cooked onions really turn this from an okay sandwich into something you'll crave again and again.

What makes this so wonderful is how basic it is. Every component has its job, and when you treat them right, they come together into something truly magical.

I've figured out that good bread makes all the difference. A nice rye brings just enough sourness to balance those sweet onions perfectly.

What You’ll Need

→ Main

01 6 slices of thick rye bread
02 3 teaspoons avocado oil
03 5 tablespoons plain butter, unsalted
04 6 ounces shredded Swiss cheese
05 2 large yellow onions, sliced very thin
06 1 pound of ground chuck (80% lean meat)
07 2 teaspoons apple cider vinegar

Step-by-Step Guide

Step 01

Over medium heat, let onions cook in butter covered for about 5 minutes. Drop the heat to low and stir them now and then for 30 to 35 minutes. They should turn a deep brown before adding vinegar to deglaze.

Step 02

Get 3 burger patties ready and wait to season them until you're about to cook. Set your griddle to reach 375–400°F.

Step 03

Sear patties in the oil for 3 minutes, then flip and cook the same on the other side.

Step 04

Smear butter across the bread slices, then place them on the griddle to toast for about 1 to 2 minutes per side.

Step 05

Put cheese, the caramelized onions, and a patty on top of each toasted bread slice. Put another slice of bread over the top. Serve hot.
