Ingredients for Keto Broccoli Cheddar Soup

• 400 g broccoli (fresh or frozen)
• 1 medium onion (or ½ tsp onion powder for lower carbs)
• 2 garlic cloves
• 2 tbsp butter
• 500 ml chicken or vegetable broth (unsweetened)
• 200 ml heavy cream (33%+)
• 150 g shredded cheddar cheese
• Salt and pepper to taste
• Optional: pinch paprika or chili flakes
• Optional: a pinch of nutmeg

Instructions

1. Sauté the aromatics: In a large pot, melt the butter over medium heat. Add the finely chopped onion and garlic, cooking for 2–3 minutes until soft and fragrant. This forms the flavor base of the soup. If using onion powder, skip this step and add it later when blending.
2. Add broccoli and broth: Add the broccoli florets to the pot, then pour in the broth. Bring to a boil, then reduce to a simmer. Cook for 10–12 minutes or until the broccoli is tender and easily pierced with a fork.
3. Blend for desired texture: Using an immersion blender, puree about half the soup directly in the pot. This thickens the base while still leaving delicious chunks. For a classic smooth cream soup, blend the entire mixture. Adjust consistency with a splash of broth if needed.
4. Add cream and cheddar: Lower the heat to the minimum. Stir in the heavy cream until fully combined. Add the shredded cheddar gradually, stirring continuously until melted. Avoid boiling at this stage—excess heat can cause cheese to separate.
5. Finish and season: Season with salt, black pepper, paprika, chili, or nutmeg according to preference. Simmer gently for 1 more minute, then serve warm.
