These burger sliders on baked sweet potato “buns” are filled with balsamic caramelized onions, crumbled feta cheese and your favorite burger toppings like sliced avocado!
These burger sliders are so easy to make and the sweet potato “buns” are the perfect addition to complete this fun meal or appetizer! Kids also love eating these because they are a great size for them!
I’m SUCH a fan of sweet potatoes. They are definitely one of my favorite foods! I’m all about the fries and the mashed potatoes and adding them to smoothies and making toast out of them and the chips and the nachos.
These sweet potato buns are made by slicing them and simply baking them in the oven! They crispy up nicely and can be made a head of time and re-heated when you are ready to assemble the burgers.
See? They are just so cute! Perfect little burger slider buns. Come on. You know you love it.
Juicy, beef burgers with golden, caramelized onions and creamy feta. Seriously bursting with so much flavor.
Ingredients you need for these sliders:
-large sweet potatoes
-spices like sea salt, pepper, garlic, parsley and red pepper flakes
I love making these for meal prep and keeping them in the fridge to reheat.
Just bake them a little less in the oven and you’ll have the perfect medium burgers (or the temperature you want use a meat thermometer!)
These burger sliders on sweet potato buns would also be a fun party appetizer that you could make the day before and reheat! And if you want the best condiment then make my Easy Paleo Mayonnaise!
If you are feeling a little extra then why not add some bacon crumbles or blue cheese crumbles or some more caramelized onions on top?
Seriously, sweet potato buns are taking over and these burger sliders are just waiting to be served!
Burger Sliders on Sweet Potato Buns
- 2-3 large sweet potatoes (20 round slices for buns)
- 1 lb ground beef
- 1 onion, sliced
- 1/2 cup milk I haven’t tested non-dairy milk
- 1 tbsp olive oil
- 1-2 tsp balsamic glaze
- 1/4 cup crumbled feta
- 2 tsp parsley
- 1 tsp garlic powder
- 1 tsp red pepper flakes
- sea salt & pepper
Preheat oven to 400 degrees.
Add ground beef to a bowl with 1/2 cup milk. This makes the beef so tender! If you have time, leave it in the fridge the night before to let the beef soak in the milk. Add the parsley, garlic powder, red pepper flakes to the meat. Take the bowl out of the fridge 45 mins before cooking to allow to come to room temperature. This ensures even cooking to the meat.
Slice sweet potatoes (leave skin on) into 1/4-1/2 inch rounds. You’ll want 20 slices for the sweet potato buns. Place on a baking sheet covered with parchment paper. Bake for 30 mins (or until tender) flipping halfway.
Slice an onion lengthwise. Heat a cast iron pan to medium-low on the stove top and add 1 tbsp of olive oil. Add the onion to the pan and cook until caramelized. Turn off the heat and add 1-2 tsp balsamic glaze. Allow onions to cool for a few minutes.
Add the caramelized onions to the ground beef mixture and 1/4 cup of crumbled feta cheese. Divide mixture into 10 slider patties on a plate with parchment paper (easy clean-up).
You can use the grill or the cast iron (then finish off in the oven) and right before cooking generously sprinkle sea salt and pepper to both sides of the burger patties.
Use the same cast iron skillet on medium heat and added the burger sliders in two batches (I actually have a HUGE cast iron skillet I can fit all of them on!) Cook for 5-7 mins flipping halfway. You just want a nice sear to the burgers. Bake the burgers in the oven for 15 mins in the cast iron pan or transfer to a large baking sheet covered with parchment paper.
Assemble the sweet potato buns, add the burger sliders and top with avocado and more feta or goat cheese! Add a slice of tomato or get fancy with some bacon!
