How to Make French Onion Patty Melt
Step 1: Caramelize the Onions
In a skillet over medium heat, sauté 2 medium sweet onions, adding a pinch of salt until they turn golden brown and sweet. This should take about 15 minutes. Stir occasionally to prevent burning.

Step 3: Cook the Patties
Increase heat to medium-high. Cook each patty for approximately 4-5 minutes per side until they reach your desired doneness.

Common Mistakes to Avoid
Avoiding common mistakes can elevate your French Onion Patty Melt experience. Here are some pitfalls to watch out for:
- Skipping the caramelization: Not taking the time to properly caramelize onions can lead to a bland flavor. Cook them slowly until they are golden and sweet.
- Overcooking the patties: Cooking beef patties for too long can make them dry. Aim for a juicy center by checking doneness with a meat thermometer or by timing carefully.
- Using cold ingredients: Starting with cold cheese or bread can result in uneven melting. Allow your cheese to come to room temperature before assembling your sandwich.
- Neglecting seasoning: Forgetting to season your beef patties will lead to a lack of flavor. Always season with salt and pepper before cooking for the best taste.
- Not grilling long enough: Rushing the grilling process may leave your bread soggy and cheese unmelted. Grill until both sides are crispy and the cheese is perfectly melted.
