📖 Instructions

1. First, let's tackle the burger patties. Gently combine the ground beef, breadcrumbs, egg, Worcestershire sauce, salt, and pepper in a large bowl. Don't overmix—we want a slightly loose texture for juicy burgers. Make sure you're wearing a clean apron, you don't wanna ruin your favorite shirt!
2. Next, shape the mixture into four equal-sized patties. I usually use a burger press for even thickness, but you can totally do this by hand—just make sure they're about 3/4 inch thick. Remember, consistency is key to perfectly cooked burgers.
3. Now, for the caramelized onions. Slice one large onion thinly, and then melt a tablespoon of butter in a large skillet over medium heat. Add the onions and a pinch of salt. Cook them slowly, stirring occasionally, until they're deeply golden brown and sweet—about 20 minutes or so. Don't rush this part; it makes a huge difference in the flavor profile of the burger. It's worth the wait, I promise!
4. Heat the same skillet again, over medium-high heat this time. Add a tablespoon of oil to prevent sticking. Once the pan is hot, gently place two of the patties in the skillet. Cook them for about 4-5 minutes per side, until they're nicely browned and cooked through. Remove them from the pan and set aside.
5. Repeat this step with the remaining two patties. Make sure not to overcrowd the pan, or the patties won't cook evenly. If you're using a larger skillet, you might be able to cook all patties at once, but monitor their cooking closely to ensure even cooking.
6. While the patties are resting, get the brioche buns ready. You can lightly toast them for that extra bit of warmth and crispness. It's a personal preference, really, but I recommend it!
7. Finally, assemble your Lunar Eclipse Burger. Spread some burger sauce or mayonnaise on the bottom half of each bun. Place a patty on the bun, top it with some of the delicious caramelized onions, a slice of cheese, and any other toppings of your choice. Don't forget to add the other bun half to finish it off!
8. There you have it—your very own Lunar Eclipse Burger! I recommend serving it immediately and enjoying every last bite. If you get a good photo, tag me on Instagram. I would love to see what you created!
9. One last thing. Don't forget to wash your hands and clean your kitchen after such a magnificent cooking experience. Remember to enjoy every step of the way!
