01 / WHAT YOU NEED

Ingredients

2 (8 ounce) packages baby portobello mushrooms, sliced 1 large onion, halved 1 large carrot, halved 1 stalk celery, halved 1 teaspoon salt 1 bay leaf 10 cups water

02 / HOW TO MAKE IT

Let's cook.

Pressure Cook Broth

Start by adding the mushrooms, onion, carrot, celery, salt, bay leaf, and water to your Instant Pot or any similar pressure cooker. Close the lid and make sure it’s locked. Set the cooker to high pressure and let it cook for 30 minutes. It will take a little while for the pressure to build up first, so be patient. Once the cooking time is up, let the pressure release naturally—this usually takes about 30 minutes. When it’s safe to open, remove the lid and give the broth some time to cool for about 20 minutes. Finally, strain the liquid through a fine sieve, discarding the veggies and herbs, and you’re left with a rich, flavorful mushroom broth.

03 / EXTRA DETAILS

Good to know.

Cook's tip

- Use a mix of different mushrooms for a more complex flavor.
- Don’t forget to sauté the mushrooms briefly before pressure cooking to enhance their aroma.
- Strain the stock well to remove any small bits for a clear broth.
