🍔 Grilled Patty Melt Perfection
Ingredients (Makes 2 hearty sandwiches):
-
½ lb ground beef (80/20 for best flavor)
-
Salt & pepper to taste
-
4 slices rye bread (or sourdough, if preferred)
-
4 slices Swiss cheese (or a mix of Swiss & American)
-
1 large yellow onion, thinly sliced
-
2 tablespoons butter (plus more for grilling)
-
Optional: Thousand Island dressing or spicy mayo for spreading
Instructions:
🔹 1. Caramelize the onions:
-
In a skillet over medium heat, melt 2 tbsp butter.
-
Add sliced onions with a pinch of salt.
-
Cook low and slow for 15–20 minutes, stirring occasionally, until deep golden brown. Set aside.
🔹 2. Shape and cook the patties:
-
Form beef into two thin patties about the shape of your bread (they’ll shrink slightly).
-
Season both sides with salt and pepper.
-
Cook in a hot skillet or griddle over medium-high heat for 3–4 minutes per side until browned and cooked through. Set aside.
🔹 3. Assemble the melts:
-
Lay out the bread slices. Spread the insides (optional) with Thousand Island or a smear of mayo.
-
Layer in this order:
-
Bread slice (buttered side out)
-
Slice of cheese
-
Beef patty
-
Caramelized onions
-
Another slice of cheese
-
Top bread slice (buttered side out)
-
🔹 4. Grill the sandwiches:
-
Wipe the skillet clean and return to medium heat.
-
Grill sandwiches 2–3 minutes per side, pressing gently, until bread is golden and cheese is melted.
-
Slice in half and serve immediately.
✅ Tips for Perfection:
-
Use room temperature butter for even spreading.
-
If you like crispy edges, add a thin layer of shredded cheese between the bread and skillet (cheese crust hack).
-
Swap in caramelized mushrooms or jalapeños for a twist.
