Melty patty melt with sauce

Patty melts with secret sauce are my go-to answer when I want a diner classic at home. This sandwich is all about layers of caramelized onions perfectly seasoned beef gooey cheese and tangy sauce stacked between golden buttery marble rye. It is hearty comfort food and always disappears fast from the table.

The first time I made these my mom said it was better than our favorite lunch spot. Now we make them on Sunday nights whenever the family craves something special.

Step-by-Step Instructions

Make the Secret Sauce:

In a small bowl whisk mayonnaise Dijon mustard barbecue sauce and hot sauce together until totally smooth and creamy The mixture should be uniform golden and free of lumps

Prepare the Beef Patties:

In a large bowl combine ground beef Worcestershire sauce salt and black pepper Mix gently by hand just until the seasonings are evenly distributed Overmixing will make dense patties

Shape the Patties:

Divide the meat into six equal portions and form into oval patties Make them wider than the bread and flatter than you think as they will shrink and thicken as they cook

Caramelize the Onions:

Melt butter in a large skillet over medium heat Add thinly sliced Vidalia onions and stir often Cook slowly for 20 to 25 minutes until soft deeply golden and fragrant This base will sweeten as it cooks

Cook the Beef Patties:

Heat another skillet on medium high Place patties in and cook for about 2 minutes on each side The goal is a fast sear while keeping the inside juicy Transfer to a plate and wipe out the pan before grilling the sandwiches

Prep the Bread:

Spread softened butter on one side of every marble rye slice Soft bread and butter make this easier and keep the bread from tearing

Assemble the Sandwiches:

Place half the bread slices butter side down on a clean skillet Spread a tablespoon of secret sauce on each Add three tablespoons caramelized onions a slice of cheddar a beef patty a slice of Swiss more onions another drizzle of sauce and cap with bread butter side out

Grill the Patty Melts:

Cook sandwiches over medium heat pressing gently with a spatula to help melt the cheese Once the bottom is golden brown flip and repeat until the cheese is oozy and the bread is crisp Let each sandwich rest for a minute before serving

This is the sandwich I crave most often on chilly Friday nights when everyone wants to stay in The sharp smell of onions browning always reminds me of my grandfather who loved stacking his sandwiches sky high

How to Store and Reheat Patty Melts

These sandwiches taste best fresh off the skillet but leftovers are still delicious Store cooled sandwiches in a sealed container in the refrigerator up to two days Put a sheet of parchment or wax paper between them so they do not get soggy To reheat set in a skillet over medium low and toast until the bread is crisp and the cheese softens again Microwaving works very fast but the bread will lose its crunch

Ingredient Swaps That Work

If Swiss cheese is missing from your fridge provolone or Monterey Jack are tasty replacements Any sturdy bread stands in for marble rye Choose sourdough or Texas toast for a change of pace The secret sauce welcomes a pinch of smoked paprika or even just a splash of pickle juice for an extra tangy kick

Shaping and Sizing Tips

Make patties wider than your chosen bread since they shrink as they cook For smaller or larger bread slices trim your cheese so every bite is even Stack carefully for balanced bites and easier eating

Serving Suggestions

Pair with diner favorites like crisp pickles sweet potato fries or a green salad Patty melts are hearty enough for a filling lunch or an impressive dinner Treat your guests with hand cut fries and fizzy soda for the ultimate retro meal at home
