Ground sirloin melts in your mouth anyway. But why not simmer some sliders in caramelized peppers and onions and serve them on a sweet little bun? Add some coarse Dijon and I am a happy camper.

Blue Ribbon Recipe

Enjoy these caramelized onion and pepper sirloin sliders as a small appetizer or meal. Full of flavor, they're small bites of deliciousness. The savory ground beef burgers with Swiss cheese on top are a nice contrast to the sweet Hawaiian roll. Adding caramelized onions and peppers elevates the sliders and, along with coarse mustard, adds a pop of flavor.

How To Make caramelized onion and pepper sirloin sliders

Test Kitchen Tips

We couldn't find the roasted red peppers in the recipe, so we created our own. We sliced a red bell pepper and a yellow onion. We caramelized the onions in a skillet with 1 Tbsp of oil and then sauteed the red pepper slices.

Step 1

Combine the meat and ketchup. Form into 12 balls and flatten into small burgers.

Step 2

Heat a large skillet over medium-high heat. Add burgers and cook until well-browned on both sides. Remove burgers from the skillet. Pour off any fat.
Step 3

Add drained onions and peppers to the skillet and heat to a simmer.
Step 4

Place the burgers back into the skillet. Reduce the heat to low. Cover and cook for 1-2 minutes or until desired doneness. Top the burgers with the cheese if desired and cook until the cheese is melted.
Step 5

To serve, spread the bottom of the buns with a little coarse ground mustard.
Step 6

Place the burgers on the buns.
Step 7

Top each with 1 heaping tablespoon of caramelized onions and peppers. Then place the top on and serve.
