Ingredients

Scale

Base Ingredients

  • 2 tablespoons extra virgin olive oil
  • 3 tablespoons butter
  • 1 small yellow onion, chopped
  • 1 carrot, chopped
  • 2 medium zucchini, chopped
  • 2 tablespoons fresh thyme leaves, plus more for serving
  • 1/4 teaspoon freshly grated nutmeg
  • 1/4 teaspoon cayenne, or more to taste
  • Kosher salt and pepper, to taste

Broth and Vegetables

  • 3 cups low sodium veggie or chicken broth
  • 4 cups broccoli florets
  • 2 bay leaves

Dairy

  • 1 cup whole milk
  • 2-3 cups shredded sharp cheddar cheese


Instructions

  1. Sauté Vegetables: Set the Instant Pot to sauté mode. Add the butter, olive oil, and chopped onion. Cook for about 5 minutes until fragrant and softened. Then add the chopped carrots, zucchini, fresh thyme leaves, nutmeg, cayenne pepper, and a generous pinch of salt and pepper. Stir to combine.
  2. Add Broth and Broccoli: Pour in the broth and add the broccoli florets along with the bay leaves. Secure the lid on the Instant Pot, select the manual/high pressure setting, and cook for 8 minutes.
  3. Release Pressure and Blend: When cooking is complete, use the quick release function to release the steam carefully. Remove the bay leaves and discard them. Transfer the soup in batches to a blender and pulse until it reaches a chunky smooth consistency, avoiding completely puréeing it. Return the blended soup to the Instant Pot.
  4. Finish Soup: Switch the Instant Pot back to sauté mode. Stir in the whole milk and shredded sharp cheddar cheese. Cook for about 5 minutes, stirring occasionally, until the cheese has fully melted and the soup is creamy.
  5. Serve: Ladle the soup into bowls and garnish with fresh thyme leaves. Serve immediately and enjoy!

Notes

  • If the cheese doesn’t melt well or curdles, you can add 2-3 tablespoons of flour during the last minute of cooking the onion in the first step to help bind the soup.
  • This recipe can also be made in a slow cooker by combining all ingredients and cooking on high for 3-4 hours or low for 4-6 hours before blending and adding cheese and milk.
  • For stovetop cooking, follow similar steps with cooking times adjusted accordingly (12-15 minutes simmering after adding broth and vegetables).
  • Use low sodium broth to control salt levels in the soup.
  • Adjust cayenne pepper quantity to your preferred spice level.
