Description

These Caramelized Onions and Mushrooms are filled with sweet flavors with the most amazing melt in your mouth texture. They taste amazing served as a side dish or over baked potatoes, burgers, steak and chicken.


Ingredients

Scale
  • 2 tablespoons salted butter
  • 2 tablespoons olive oil
  • 4-5 ounces of baby bella mushrooms (also known as cremini)
  • 1 large yellow onion (or 2 small onions)
  • 1/2 teaspoon salt
  • 1/8 teaspoon black pepper
  • 1/8 teaspoon dried thyme
  • 2 garlic cloves
  • 1 teaspoon balsamic vinegar

Instructions

  1. Slice the bottom 1/8 inch of the stem of the mushrooms and discard. Then, slice the mushroom into 1/4 inch slices. Peel the onion and slice in half, then cut into 1/4 inch slices.
  2. Heat the stovetop to medium low heat. Add the butter with 1 tablespoon of olive oil into a large stainless skillet. Toss in the onions and sauté for 10 minutes, stirring halfway through.
  3. Sprinkle in salt, pepper and thyme and continue to cook on medium low heat for another 10 minutes, stirring every 2-3 minutes. Remove onions to a plate and set aside.
  4. Add mushrooms in a single layer to the skillet and drizzle over the remaining 1 tablespoon of olive oil. Cook for 4 minutes, then flip and cook another 3 minutes.
  5. Add the onions back into the skillet. Toss in the minced garlic and 1 teaspoon of balsamic vinegar. Allow the mixture to cook for another 3-5 minutes, stirring frequently.
  6. Serve as a topping or side dish and enjoy!

Notes

  • Try to slice the onions about 1/4 inch thick and similar in size so they cook evenly.
  • I prefer a stainless steel skillet for this recipe because they distribute heat well and caramelize veggies perfectly. 
  • If the butter starts to burn or the onions brown too much too quickly, reduce the heat.
  • Caramelized onions are supposed to cook low and slow. Make sure to be patient and cook the entire time for the best flavor.
