I have made these little burger sliders in a casserole dish so many times, it’s almost funny! We do not only eat them for appetizers at parties, or on game day as we grill, but we make them on the stove for just my husband and I quite regularly as a main meal. I mean, we just absolutely love these! The mix of flavors between the caramelized onions, the melty cheese and that perfectly cooked patty inside a soft bun (pro tip: use Hawaiian rolls), is just out of this world!
Check out what our friends over at Host the Toast had to say about this:
“However, I’m pretty sure that this one right here is the reigning king of all things French onion. Friends, meet French Onion Beef Sliders.”
Yep! I have made a host of other French onion recipes, but this one is the best!
Ingredients
8 tablespoons (1 stick) Land O’ Lakes butter, divided
2 large sweet onions, sliced
2 pounds ground beef
2 tablespoons Better than Boullion beef base, divided
1 tablespoon Worcestershire sauce, divided
Kosher salt and black pepper, to taste
24 Hawaiian slider buns
12-16 ounces gruyere cheese, chopped
2 tablespoons sesame seeds
1 tablespoon fresh thyme
1 teaspoon onion powder
1 teaspoon garlic powder
Instructions
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 beef with half of the beef base and half of the Worcestershire sauce. Season generously with salt and pepper.
Add the beef to the skillet full of onions. Increase heat to medium-high and brown the beef, breaking it up and mixing with the onions as you go. Once browned, drain off excess grease.
Preheat the oven to 350°F. Lightly grease a large baking sheet. Separate the tops from the bottoms of the slider buns. Fit the slider bottom buns tightly on the baking sheet.
Evenly distribute the beef and onion mixture over the bottom buns. Top with the gruyere cheese. Cover with the top buns.
In a microwave safe bowl, melt the butter with the remaining beef base. Stir in the remaining 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.
Bake the sliders until the cheese is fully melted and the tops of the rolls are lightly browned, about 20 minutes.
