Prep time


Cooking time




  • 2 large onions, thinly sliced

  • 8 oz (about 225g) of mushrooms, sliced

  • 2 tablespoons of butter or olive oil

  • Salt and pepper to taste


  • Prepare the Onions: Begin by slicing the onions thinly. This will ensure they caramelize evenly. A sharp knife is your best friend for this task.
  • Heat the Pan: In a large skillet, heat the butter or olive oil over medium-low heat. You want the heat to be low enough to allow for slow caramelization without burning.
  • Add the Onions: Once the butter or oil is hot, add the sliced onions to the pan. Stir them around to coat them with the fat evenly.
  • Caramelize the Onions: Cook the onions over low to medium-low heat, stirring occasionally. This process takes time; it can take anywhere from 20 to 45 minutes to achieve the desired caramelization. The onions should turn a rich, golden brown, and their sweetness should intensify.
  • Add the Mushrooms: When the onions are caramelized to your liking, add the sliced mushrooms to the pan. Mushrooms contain a lot of moisture, so be prepared for them to release liquid when they start cooking.
  • Sauté the Mushrooms: Continue to cook the mixture until the mushrooms become tender and slightly browned, usually about 10-15 minutes.
  • Season: Season the caramelized onions and mushrooms with salt and pepper to taste. You can also add fresh herbs like thyme or rosemary for an extra layer of flavor.


  • That’s it! You’ve just made a delicious batch of caramelized onions and mushrooms. You can serve them as a side dish, mix them into pasta or risotto, or use them as a topping for burgers or pizzas.

Tips and Tricks

Caramelizing onions and mushrooms may be a straightforward process, but there are some tips and tricks that can elevate your culinary prowess and ensure the best results:

Caramelized Onions and Mushrooms

1. Low and Slow

Caramelization is all about patience. Keep the heat low and cook the onions and mushrooms slowly to bring out their natural sweetness. Rushing the process can lead to uneven or burnt results.

2. Uniform Slicing

When preparing the onions, make sure to slice them uniformly. This ensures that they cook evenly and caramelize uniformly. Uneven slices can lead to some pieces being undercooked while others are overly browned.

3. Don’t Overcrowd the Pan

Avoid crowding the pan with too many onions and mushrooms. Overcrowding can lead to moisture being released and steaming rather than caramelizing the ingredients.

Cook them in batches if needed.

4. Season Thoughtfully

Season your caramelized onions and mushrooms toward the end of the cooking process. Adding salt too early can draw out moisture and interfere with caramelization.

5. Add a Splash of Liquid

If you find your onions or mushrooms sticking to the pan, you can add a small amount of water, broth, or white wine to deglaze and loosen any flavorful bits that have stuck to the pan.

6. Storage and Reheating

Caramelized onions and mushrooms store well in the refrigerator for several days. Reheat them gently in a pan with a little butter or oil when ready to use.
