For the Onions

- 3 yellow onions (sliced thin)
For the Patties
- 2 pounds ground beef
- 1 tablespoon ketchup
- ½ teaspoon garlic powder
- 1 teaspoon salt
- ½ teaspoon pepper
For Assembly
- 2 cups Gruyere cheese (shredded)
- 12 slices Texas toast
For the Aioli Spread
- 8 teaspoons mayonnaise
- ⅓ cup mayonnaise
- 1 tablespoon lemon juice
- 1 teaspoon pepper
- 1 tablespoon (about 3 cloves) garlic (minced)

How to Make French Onion Patty Melt
Step 1: Caramelize the Onions
In a medium skillet, melt butter over medium-low heat. Add onions and cook until caramelized (about 15-20 minutes), stirring often. Add water as needed to prevent burning. Remove from skillet and tent to keep warm.
Step 2: Prepare the Beef Patties
In a large bowl, mix together ground beef, garlic powder, salt, and pepper. Make 8 square patties (a little larger than the bread). Each patty should be about ¼ inch thick.
Step 3: Cook the Patties
Wipe out the skillet and set the heat to medium-high. Add hamburger patties in batches (two at a time) and cook 1-2 minutes per side. Remove patties from skillet and set aside.
Step 4: Toast Texas Toast
Toast 4 pieces of Texas toast until golden brown and set aside.
Step 5: Make Aioli Spread
In a small bowl, combine mayonnaise, lemon juice, pepper, garlic, parsley, and ketchup to make the aioli spread.
Step 6: Assemble Sandwiches
Top 4 untoasted slices of bread with cheese, hamburger patty, onions, then add toast spread with aioli on both sides. Layer more cheese on top followed by a second beef patty, more onions, then cover with another slice of bread.
Step 7: Grill Sandwiches
Spread 1 teaspoon of mayonnaise on top of each sandwich. Wipe out skillet again and set heat to medium. Place sandwiches in pan mayo side down. Place a weighted pan on top to hold sandwiches firmly in place. Cook until golden brown (about 3 minutes). Remove weighted pan. Spread 1 teaspoon mayo on top slice of bread and flip carefully. Cook for another 3 minutes or until golden brown. Serve warm.

How to Perfect French Onion Patty Melt
Creating the perfect French Onion Patty Melt requires attention to detail. Here are some tips to ensure your sandwich turns out delicious every time.
- Use Quality Beef: Choose ground beef with some fat content (80/20) for juicier patties that won’t dry out during cooking.
- Caramelize Slowly: Take your time caramelizing onions; low heat over a longer period will bring out their natural sweetness.
- Grate Cheese Fresh: Use freshly grated Gruyere cheese instead of pre-shredded for better melting and flavor.
- Press While Cooking: When grilling your sandwiches, press down slightly with a weighted pan to ensure even browning and melting.
- Toast Your Bread: Lightly toast your Texas toast before assembling; this helps keep the bread from getting soggy from the fillings.
Best Side Dishes for French Onion Patty Melt
Pairing side dishes with your French Onion Patty Melt can enhance its flavors. Here are some great options:
- French Fries: Classic crispy fries complement any sandwich beautifully; try seasoning them with garlic powder for added flavor.
- Coleslaw: A tangy coleslaw provides crunch and acidity that balances the richness of the patty melt.
- Potato Chips: Crispy potato chips offer texture and make for an easy, no-fuss side option; choose flavored varieties for an extra kick.
- Corn on the Cob: Grilled corn is sweet and juicy, making it an excellent pairing with savory sandwiches like this one.
- Roasted Vegetables: Seasoned roasted veggies add color and nutrients; try carrots, zucchini, or bell peppers as great choices.
- Macaroni Salad: A creamy macaroni salad brings comfort food vibes that pair well with hearty sandwiches like the French Onion Patty Melt.
Common Mistakes to Avoid
Making a French Onion Patty Melt is simple, but there are a few common pitfalls to watch out for.
- Using the wrong bread: Texas toast is ideal for this recipe. Avoid using thin slices of bread, as they won’t hold up to the hearty filling.
- Overcooking the beef: Ground beef should be cooked just enough to maintain juiciness. Avoid cooking it too long as this will lead to dry patties.
- Not caramelizing onions properly: Take your time with the onions. If you rush, they might burn instead of caramelizing. Stir them often and add water if necessary.
- Skipping the aioli spread: This spread adds flavor and creaminess. Don’t skip it! Ensure you mix it well for an even taste.
- Neglecting to weigh down sandwiches: Pressing the sandwich while cooking helps achieve that golden crust. Use a heavy pan or skillet on top for best results.

Reheating French Onion Patty Melt
- Oven: Preheat to 350°F (175°C). Place sandwiches on a baking sheet and heat for about 10-15 minutes until warm.
- Microwave: Heat on medium power for 1-2 minutes. Be cautious, as this can make the bread soggy.
