Planked Beef Sliders with Provolone, Roasted Red Peppers and Caramelized Onions

Perfect little planked burgers topped with provolone cheese, roasted red peppers and caramelized onions. These burgers are so incredibly tasty but seriously easy to make. They would be perfect for game day!

Ingredients

For the Caramelized Onions:

  • 2 tablespoons butter
  • 1 sweet onion sliced thinly

For the Burgers:

  • 1 pound of ground beef
  • Salt and pepper to taste
  • 12 thin slices of Provolone cheese
  • 1/2 cup of roasted red peppers chopped
  • Caramelized onions cooked in advance
  • Slider buns

Instructions

How to Prep Your Plank:

  1. Soak your plank for at least an hour, but 2 hours is better for this recipe. Soak in water seasoned with a touch of salt.

For the Caramelized Onions:

  1. I do mine right on the grill. Preheat the grill to medium high heat. Take a cast iron skillet and spray it generously with non stick spray. Add butter. Let it start to sizzle a bit. Then add the onions.
  2. Cook them for about 10 to 15 minutes, you to keep a close eye on them, and stir them about as needed. You want them to start to turn a nice amber colour. Once they're done take them off the heat carefully and set aside till you need them. Careful when handling a cast iron pan that's hot. We want the onions to sizzle, not your hands!

For the burgers:

  1. Shape your sliders so they are just slightly bigger than your slider buns. Press your thumb into the middle of the burger just enough to indent it slightly.
  2. Sprinkle with salt and pepper.
  3. Pop your plank on the grill for a few minutes. It's going to get a big of a curl to it. So don't put the food on it yet. Once it gets a slight bend carefully turn it over with tongs. Now you can add your burgers to the plank.
  4. Pop the top of the grill down and allow them to cook for about 7 to 10 minutes for medium well.
  5. Lift the lid, turn the burgers over with tongs, and put the lid back down for about 4 to 7 minutes.
  6. Lift the lid and add the cheese. I used one slice of cheese per burger. I'm nuts for cheesy burgers.
  7. Pop the lid down and allow them to cook just till the cheese melts, about 2 minutes.
  8. Top with roasted red peppers and caramelized onions.
  9. Carefully remove the burgers from the plank.
  10. Slide on the toasted buns.
  11. Serve with a big old cheesy smile!

How to toast buns on the grill:

  1. Spread a little butter on the inside of the buns. Pop them on a hot grill, butter side down, and allow them to cook briefly, about 1 to 2 minutes. You just want them slightly brown.

Recipe Notes

Adapted from Bobby Flay's Philly Burger

We like our burgers with no pink so adjust the time depending on how you like your burgers. Also remember using the plank means the burgers will take a tad longer to cook than placing them right on the grill grate. You can use a meat thermometer if you're unsure how to time them perfectly.
