Ingredient Breakdown
This recipe uses fresh ingredients that bring out bold flavors in each bite of your Smoky Mayo Beef Patty Melts. Here’s exactly what you need and why each item matters.
Ground Beef (80/20 blend) – 1 pound
The 80/20 blend gives you the perfect balance of juicy meat and flavor without being too greasy. It ensures your patties stay moist while adding deep savory notes that pair well with cheese and smoky mayo.
Sourdough Bread – 8 slices
Sourdough’s mild tang holds up well when grilled and resists getting soggy from the juicy filling. Its sturdy structure is essential in keeping all ingredients together through every bite.
Swiss Cheese – 8 slices
Swiss cheese melts smoothly with just enough sharpness to stand up to beef and smoky mayo. Its creamy texture is perfect for creating that iconic cheese pull when you slice the finished sandwich.
Mayonnaise – 1/3 cup
The base for smoky mayo provides creaminess to the sauce. It blends smoothly with smoked paprika and Dijon mustard for an easy spread that brings everything together without overpowering other flavors.
Dijon Mustard – 1 tablespoon
Dijon mustard adds a subtle heat and depth to the smoky mayo without dominating the overall taste. It balances out the richness from mayonnaise wonderfully.
Worcestershire Sauce – 1 teaspoon
This umami-rich condiment deepens the complexity of both beef patties and smoky mayo sauce. Just a dash makes all other flavors pop without being too salty or overwhelming.
Yellow Onion – 1 large (thinly sliced)
Sautéed onions add sweetness that offsets some of the savory elements of this dish. Their tender texture melds into each bite while providing aromatic warmth to your melts.
Butter – 3 tablespoons (softened)
Spreading softened butter on bread before grilling gives it a golden crust that is crisp yet soft inside. It prevents sticking while enhancing overall flavor during cooking.
Kosher Salt & Black Pepper – to taste
A pinch of salt and pepper seasons both hamburger patties and onions perfectly. Adjust amounts as desired; they bring out natural flavors in meat and vegetables alike.

Step By step Recipe: Smoky Mayo Beef Patty Melts
This section guides you through preparing every element of your Smoky Mayo Beef Patty Melts so each layer stands out but comes together in a harmonious bite. Follow these steps for best results:
Step 1: Make the Smoky Mayo Sauce
Add one-third cup mayonnaise to a bowl along with one tablespoon Dijon mustard, 1 teaspoon smoked paprika, and one teaspoon Worcestershire sauce. Mix thoroughly until smooth and creamy, then cover and refrigerate until ready to assemble sandwiches.
Step 2: Shape & Season Beef Patties
Divide one pound ground beef into four equal portions. Gently form each portion into oval-shaped patties approximately half an inch thick. Sprinkle both sides evenly with kosher salt and freshly cracked black pepper; do not overwork meat to keep patties tender.
Step 3: Caramelize Onions
Add one tablespoon butter to a skillet set over medium-low heat. Toss in thinly sliced yellow onion and stir frequently as onions soften and turn translucent. Cook gently until golden brown, about 12 minutes, stirring occasionally to prevent sticking or burning.
Step 4: Cook Beef Patties
Add beef patties directly into a preheated skillet over medium-high heat. Sear each side until nicely browned, about 3 minutes per side, cooking to your desired doneness. Remove and let rest briefly on a plate tented with foil.
Step 5: Assemble Sandwich Layers
Spread smoky mayo generously on one side of each bread slice. Layer 4 bread slices, mayo side down, with a slice of Swiss cheese, seared patty, caramelized onions, another slice of Swiss, and top with remaining bread slices, mayo side up.
Step 6: Grill Your Patty Melts
Melt remaining butter in a clean skillet over medium-low heat. Place sandwiches in the skillet and cook until golden brown and crispy, about 3–4 minutes per side, pressing gently with a spatula. Repeat with remaining sandwiches.
Step 7: Serve
Slice each patty melt in half and serve immediately. Optional: add pickles or extra smoky mayo on the side. Enjoy while hot and melty!
Serving and Storing Tips
Slicing & Serving Suggestions
Let sandwiches rest two minutes before slicing diagonally. Serve with simple sides like fries, salad, or pickles to complement the creamy and savory flavors.
Storing Leftovers Properly
Cool sandwiches completely, wrap tightly in foil or plastic, and refrigerate up to three days. Reheat in a low oven to maintain crispness.
Best Way To Reheat For Maximum Crispiness
Reheat in a 350°F oven uncovered for 5–7 minutes until interior is warmed and crust is crisp. Microwave only as last resort.
Freezing For Later Meals
Wrap sandwiches individually in foil, store in airtight freezer bag. Defrost overnight in the fridge, then reheat in oven for best texture.
Mistakes to avoid
Using Cold Ingredients
Cold patties or sauce can lead to uneven cooking. Let beef come to room temperature and spread smoky mayo while soft and creamy.
Overcrowding the Skillet
Cooking too many sandwiches at once can lower temperature, causing steaming instead of searing. Leave space for a crisp crust.
Skipping Rest Time
Cutting too soon can let juices escape, making bread soggy. Let sandwiches rest a couple of minutes before slicing.
Tips and tricks
Choose the Right Bread
Use sturdy slices like rye or sourdough to hold juicy patties and creamy smoky mayo. Butter each slice for a golden, crispy finish.
Balance Meat and Cheese Ratios
Shape thinner patties for proper fit. Layer enough melty cheese and smoky mayo to balance flavors without overpowering the beef.
Crisp Onions Properly
Cook onions low and slow until golden and sweet. Properly caramelized onions add depth and contrast to beef, cheese, and smoky mayo.
Suggestions for Smoky Mayo Beef Patty Melts
Add Pickled Ingredients
Layer pickles or pickled jalapeños inside your melt for tangy crunch that contrasts with creamy smoky mayo and tender beef.
Try Different Cheeses
Swap Swiss for pepper jack, Gruyère, or provolone to explore different flavors and melt textures.
Go Vegetarian
Substitute beef patties with veggie burgers or grilled portobello caps. Smoky mayo keeps bold flavor intact.
