French Onion Beef Sliders

My friend Leslie cooked these suckers up at a courthouse board meeting and they were nuts. We ended up making them the next night and it was a big winner with the fam. If you want something delicious that you can make in bulk, I highly recommend these. I changed the recipe a little bit to add some more protein, and I subbed a few things. Go make them, the hardest part is being patient with the onions!

Time to prep: 10 minutes

Time to done: 1 hour 15 minutes

INGREDIENTS

Meat and Onions

2 tbsp. butter
2 large sweet onions, sliced
3 pounds ground beef or turkey
1 tbsp. soy sauce
1 tbsp. Worcestershire sauce
Kosher salt and black pepper to taste

The Rest

36 slider buns
16 ounces gruyere cheese, chopped
1 tbsp. soy sauce
1 tbsp. Worcestershire sauce
6 tbsp. butter
2 tablespoons sesame seeds
1 tablespoon fresh thyme
1 teaspoon onion powder
1 teaspoon garlic powder

DIRECTIONS

Melt 2 tablespoons of the butter in a skillet over medium heat. Add in the onions and reduce the heat to medium low. Cook stirring occasionally, until lightly caramelized, about 25-30 minutes. If the onions start to look dry or burnt, add a tablespoon of water to the pan.

In a large bowl mix the ground protein with soy sauce and the Worcestershire sauce. Season with salt and pepper.

Add the protein to the skillet with the onions. Increase heat to medium-high and brown the protein breaking it up and mixing with the onions as you go. Once browned, drain off excess grease.

Preheat oven to 350 degrees. Lightly grease a large baking sheet. Separate the tops from the bottom of the slider buns. Fit the slider bottom buns tightly on the baking sheet.

Evenly distribute the protein and onion mixture over the bottom buns. Top with gruyere cheese. Cover with the top buns.

In a microwave-safe bowl, melt the 6tbsp. butter with the soy sauce. Stir in the Worcestershire sauce and continue to mix until well combined. Using a pastry brush, brush the beefy butter mixture over the top buns. Sprinkle with the sesame seeds, thyme, onion powder and garlic powder.
