Ingredients
Sauté Ingredients
- 1 tbsp (15 ml) oil (or water sauté to make oil-free)
- 1 medium (150 g) onion minced
- ½ tsp minced garlic
- 2 cups (150 g) minced mushrooms
- 2 tbsp (15 g) minced celery or
- 1 tsp celery seeds
- 1 cup (180 g) tri-color quinoa, or any color
Pressure Cooker Ingredients
- 2½ cups (590 ml) water
- 1 cup (140 g) chopped golden beets
- ¾ cup (150 g) black beluga lentils (can substitute French lentils)
- ½ cup (65 g) chopped carrot
- 2 small bay leaves
- 1½ tsp (3 g) dried marjoram
- 1 tsp dried thyme
- ½ tsp dried basil
- 2 cups (680 g) Romanesco or cauliflower florets
Instructions
- Turn your Instant Pot to sauté. Add the oil and cook the onion until translucent, 3 to 5 minutes. Add the garlic and mushrooms. Sauté until the mushrooms are soft, about 5 minutes. Add the celery and quinoa, and sauté for 1 minute to lightly toast.
- Turn the sauté off, then add the water, beets, lentils, carrot, bay leaves, marjoram, thyme and basil to your Instant Pot.
- Wrap the Romanesco florets in foil and place on top of the stew. This will slow the cooking so they don’t get mushy.
- Cook on high pressure for 10 minutes and manually release the pressure. Carefully remove and open the foil packet.
- Remove the bay leaves. Dish up the stew into four bowls and divide the Romanesco florets between the 4 servings.
