Ingredients
Method
- Heat the olive oil in a skillet over medium heat. Sauté the onion until translucent, about 5 minutes.
- Add the minced garlic and cook for 1 minute, until fragrant.
- Transfer the onion and garlic to the slow cooker.
- Add the broccoli florets, chopped stems, and vegetable broth. Stir in the milk, cheddar cheese, Dijon mustard, salt, pepper, lemon juice, and butter.
- Cover and cook on low for 6 hours, or until the broccoli is tender.
- During the last 30 minutes of cooking, add the small piece of carrot I mentioned in the notes to naturally sweeten the soup.
- Just before serving, stir in the heavy cream for extra richness.
- Use an immersion blender to puree the soup until silky smooth, or transfer in batches to a countertop blender.
- Serve hot, garnished with a few reserved florets and a sprinkle of extra shredded cheddar.
Notes
I discovered that adding a small piece of carrot during the last hour of cooking sweetens the soup naturally and adds a subtle depth of flavor. Also, reserving a few florets for garnish keeps the soup bright.
