Sweet Potato Smash Burgers

1: Thinly slice the onion, then add it to a large skillet over medium-low heat with olive oil and butter. Season, add in 1/4 cup of bone broth, and let the onions cook down, mixing every few minutes.

2: Once the liquid is gone, add another 1/4 cup of bone broth and mix every few minutes until the onions are almost done, then add in the maple syrup and let finish caramelizing.

3: While the onions are cooking, peel the sweet potato and cut it into ~1/3 inch circular slices. Add to a lined baking sheet, coat with avocado oil spray, and season both sides. Roast at 400°F until crispy and soft (about 30 minutes, flipping halfway through).

4: Add ground beef to a bowl, season generously, mix well, and form into 6 balls. Heat a skillet over medium-high heat, spray with oil, then place the meatballs on and smash them down thin and evenly.

5: Flip the patties after 1.5-2 minutes and add cheese on top while the other side finishes cooking.

6: Assemble the burgers and enjoy!
