Beef Liver and Onions

### Instructions:

1. **Prepare the Liver**: Start by rinsing the liver slices under cold water and patting them dry with paper towels. If desired, lightly dust the liver slices with flour. This helps create a nice golden crust when frying. Season the liver generously with salt and pepper on both sides.

2. **Caramelize the Onions**: Heat 1 tablespoon of olive oil or butter in a large skillet over medium heat. Add the sliced onions and cook them slowly, stirring occasionally, until they are golden and soft. This process can take about 10-15 minutes. The slow cooking allows the onions to release their natural sweetness, which complements the liver perfectly. If the onions start to stick, add a splash of water or broth to deglaze the pan.

3. **Cook the Liver**: In a separate skillet, heat the remaining olive oil or butter over medium-high heat. Once hot, add the liver slices and cook for about 2-3 minutes per side, or until browned on the outside but still slightly pink inside. Overcooking the liver can make it tough, so be sure not to leave it on the heat too long.

4. **Combine and Add Flavor**: Once the liver is cooked, add the caramelized onions back into the pan with the liver. Pour in the beef broth and bring to a simmer. This will deglaze the pan and infuse the liver with the rich, sweet onion flavor. If you like, add a tablespoon of balsamic vinegar for extra depth.

5. **Serve**: Once the liquid has reduced slightly, check for seasoning and adjust with salt and pepper if needed. Serve the beef liver and onions hot, garnished with fresh parsley for a pop of color.

### Tips for the Best Beef Liver and Onions:
– **Don’t Overcook the Liver**: Liver should be cooked just enough to brown on the outside, leaving the inside tender and slightly pink. Overcooking it can make it tough and dry.
– **Caramelize the Onions Slowly**: The key to sweet, tender onions is patience. Cooking them over low to medium heat allows them to develop their sweetness without burning.
– **Add Variety with Seasonings**: Experiment with other seasonings such as thyme, garlic, or smoked paprika to personalize the dish to your liking.
