What You’ll Need

Here are the ingredients you’ll need to make fajita sliders at home. See the recipe card located at the bottom of the post for full instructions.

  • Ground Beef– I like to use a lean ground beef 80% lean or higher.
  • Fajita Seasoning Mix– Check in the seasoning section of the grocery store. You can substitute taco seasoning mix if needed.
  • Cheese Slices– I like to use cheddar cheese for these sliders. Any of your favorite variety works great.
  • Onion– White onion works great for the recipe.
  • Red Bell Pepper– Thinly slices of red bell pepper is used to top on the sliders.
  • Mayonnaise– Mayonnaise is used on the rolls for the sliders.
  • Hawaiian Sweet Rolls– I like to use Hawaiian Sweet Rolls for these sliders, but any small roll will work just fine.
  • Lettuce– Iceberg or romaine are great for the sliders.

How To Make Baked Sliders

Preheat Oven and Prepare Baking Dish. Preheat oven to 350 degrees and spray a 9×13 inch baking dish lightly with non stick cooking spray.

Prepare Ground Beef Mixture. Place ground beef and Fajita Seasoning into a large mixing bowl, stirring to combine. Transfer beef to prepared baking sheet and press down evenly into dish.

Bake. Bake for 30 minutes, or until baked through. Remove and drain grease if necessary.

Add Cheese. Top with cheese slices and return back to oven for a couple minutes to melt cheese. Remove and cut burgers into appropriate squares to fit your slider rolls.

Cook Onions and Peppers. While burgers are baking, heat oil into a large skillet over medium heat. Add sliced onions and red bell peppers, stirring until softened. Takes about 10 minutes, stirring often.

Arrange Sliders. Spread mayonnaise onto rolls and layer with a burger, onions and peppers, then lettuce leaf. Close with top roll and use a long toothpick to keep together if desired. Serve warm.

    What an amazingly simple idea! I love beef fajitas, and this is the perfect spin on them. Baking in a 9×13 is much less work than firing up the grill, for sure! Thanks for the awesome recipe!

  5. Tracy

    What a GREAT idea! I am so doing this better than grease splattering everywhere or heating up the grill! Fabulous:)

  6. Heather Christo

    These are the cutest little sliders! I am not really looking forward to the chaos of the school year starting, but these would help!

  7. Jessica | Saucy Pear

    Why have I never thought to make slider patties in a 9×13 and then just cut them out?! I’d avoid the dreaded “the patty is smaller than the bun” syndrome!

  8. Heather @ Shards of Lavender

    My whole family would love these, especially on Hawaiian Sweet Rolls. Thanks for the easy recipe!
