Sliders: In-N-Out Pull Apart

These In-N-Out Pull Apart Sliders are unfussy and flavor-packed! An notable filling of caramelized onions and au jus seasoned ground beef, In-N-Out spread and melty cheese sandwiched between toasty brioche slider buns. Serve with spicy peppers, French fries or potato wedges and extra spread on the side. Yields 12 sliders and will yield 6 (2 slider) servings.

I’ve got a flavor-packed recipe for you!

Inspired by In-N-Out, these sliders are so well-seasoned and simple. Brioche slider buns topped with American cheese, a well-seasoned ground beef mixture and kitchen-made In-N-Out spread. Baked until melty and the buns, slightly toasted – with French fries, hot peppers and extra spread on the side. You can also add lettuce, onion and tomato after they come out of the oven, but either way you serve them, they are notable.

I hope you love them as much as we do!

To Make These In-N-Out Sliders Gather:

• In-N-Out spread – I shared the recipe for my from-scratch spread here.
• unsalted butter – Lends flavor and fat for sautéing.
• yellow onion – Lends subtle sweetness and caramelized onion flavor.
• kosher salt – Helps to soften the onions when caramelizing.
• ground beef – Use any ground beef you prefer.
• au jus gravy mix – Use from-scratch or store-bought.
• brioche slider buns – Or substitute regular slider buns or Hawaiian slider rolls.
• american cheese – Lends smooth and gets ultra creamy once melted.

Make The In-N-Out Spread:

I shared this method a year or so ago. It consists of mayo, ketchup, mustard, dill pickle relish and vinegar. It’s pretty similar to Big Mac sauce and it’s deliciously addictive. I put the recipe below the slider recipe at the end of this post.

Make The Beef Filling:

In a 10 or 12-inch skillet, add 2 tablespoons unsalted butter and 1 large finely diced yellow onion with a pinch of kosher salt.

Cook over medium to medium-low heat, stirring often until the onions are tender and caramelized.

Next, add in 1 pound of ground beef.

Use a spatula to break up the meat into small crumbles, tossing with the caramelized onions and cook thoroughly.

Once cooked, drain and discard any fat in the pan. Next, measure and add 1½ tablespoons of au jus gravy mix.

Stir until combined and remove off of the heat.

Preheat your oven to 375°F (or 190°C).

Build The Sliders:

Line a rimmed baking sheet with parchment paper. Using a serrated bread knife, slice the slider buns in half horizontally, placing the bottom half of the sliders onto the prepared pan.

Top with 6 to 8 slices of American cheese and top with the beef and onion mixture.

Spread the beef and onion mixture evenly.

Drizzle with 1/3 cup of the In-N-Out spread.

Top with 4 to 6 more slices of American cheese, tearing them to fit if necessary.

Replace the top half of the sliders and bake in your preheated oven for 8 minutes or until the cheese has melted and the sliders are heated through.

That’s truly it! Although you could remove the top halves and top with thinly sliced tomato and crisp iceberg lettuce.

Serve with french fries or potato wedges, tots or a simple salad.
