How to Make French Onion Patty Melt
Step 1: Caramelize the Onions
In a medium skillet, melt butter over medium-low heat. Add sliced onions and cook until they are deeply caramelized, about 15-20 minutes. Stir often and add water as needed to prevent burning. This step is crucial as it brings out the natural sweetness of the onions, creating that classic flavor we love from French onion soup.
Step 2: Prepare the Patties
In a large bowl, mix together ground beef with garlic powder, salt, and pepper. Shape into eight square patties slightly larger than your bread slices—they should be about ¼ inch thick. Making these patties uniform helps them cook evenly and fit perfectly into your sandwich.
Step 3: Cook the Patties
Wipe out the skillet from your onions and increase the heat to medium-high. Cook hamburger patties in batches (two at a time) for 1-2 minutes per side until browned. Don’t overcook them; they will continue cooking when they’re assembled in the sandwich!
Step 4: Toast Some Bread
Toast four pieces of Texas toast until golden brown. This adds crunch that contrasts beautifully with gooey cheese and juicy meat.
Step 5: Make Your Aioli Spread
In a small bowl, combine mayonnaise, lemon juice, pepper, garlic, parsley, and ketchup to create a delicious aioli spread. This creamy concoction adds zest to every bite!
Step 6: Assemble Your Sandwiches
On four untoasted slices of bread, layer shredded cheese first followed by a hamburger patty topped with caramelized onions. Spread aioli on both sides of another slice of toast before placing it on top. Add more cheese, place another patty atop that along with more onions before topping it off with another slice of bread.
Step 7: Grill It Up!
Spread one teaspoon of mayonnaise on top of each assembled sandwich. Wipe out your skillet again (to avoid burnt bits) and place sandwiches in with mayo side down. Use a weighted pan on top to keep them flat while cooking until golden brown (about 3 minutes). Carefully flip sandwiches after spreading mayo on top slice and cook for another 3 minutes until both sides are crisped up nicely.
Serve these warm French Onion Patty Melts while they’re still cheesy and deliciously melty! Enjoy every mouthful as they bring smiles around your dinner table!
Pro Tips for Making French Onion Patty Melt
Making the perfect French Onion Patty Melt is all about attention to detail and flavor. Here are some pro tips to elevate your dish!
- Caramelize onions slowly: Cooking your onions low and slow allows their natural sweetness to develop fully, creating a rich flavor that makes the melt irresistible.
- Use high-quality cheese: Opt for good-quality Gruyere cheese, as it melts beautifully and adds a nutty flavor that complements the savory beef and sweet onions.
- Don’t overcrowd the skillet: When cooking your patties, cook them in batches. Overcrowding can lower the pan’s temperature, preventing a nice sear and juicy texture.
- Press down while cooking: Using a weighted pan on top of your sandwiches helps ensure even cooking and creates that delicious crispy crust everyone loves.
- Let it rest before serving: Allowing your patty melts to sit for a couple of minutes after cooking helps the flavors meld together and makes it easier to slice!
How to Serve French Onion Patty Melt
Presenting your French Onion Patty Melt can turn a simple meal into something special. Here are some fun ideas!
Garnishes
- Fresh herbs: Sprinkle fresh parsley or chives on top right before serving for a pop of color and an added freshness.
- Caramelized onion drizzle: A spoonful of extra caramelized onions drizzled on top adds elegance and enhances the onion flavor.
Side Dishes
- Crispy French Fries: Golden, crispy fries are always a hit. They add crunch and pair perfectly with the melty goodness of the patty melt.
- Mixed Green Salad: A light salad with vinaigrette provides balance to the rich flavors of the melt. Use seasonal greens for freshness!
- Coleslaw: Crunchy coleslaw offers a refreshing contrast to the warm sandwich. Its tangy flavor complements the richness of the cheese.
- Pickles or Pickled Vegetables: The acidity from pickles cuts through the richness of the melt, adding brightness and extra flavor with every bite.
