This creamy keto chicken broccoli soup is perfect for busy weeknights when you want something comforting and nourishing without any fuss. It brings together tender chicken, vibrant broccoli, and a smooth cauliflower blend that feels indulgent but keeps carbs low.
I discovered this recipe on a hectic evening when I had just a few ingredients on hand and wanted something cozy. It quickly became a staple for chilly nights when I want warm comfort without the guilt.
Ingredients
- Cauliflower florets: form the creamy base. Pick bright white fresh heads for the best flavor and texture.
- Broccoli: adds freshness and a nice bite opt for firm green florets without yellowing.
- Chicken: provides lean protein use cooked chicken for ease or rotisserie for flavor.
- Better Than Bouillon chicken base: boosts depth but you can sub stock or broth.
- Parmesan cheese: melts into the cauliflower to enhance richness choose a good quality aged cheese if possible.
- Olive oil: adds smoothness and richness pick extra virgin for the best taste.
- Butter for sautéing: brings warmth and aroma use unsalted for control over seasoning.
- Garlic, dried minced onion, thyme and onion powder: layer flavors choose fresh garlic cloves for the brightest taste.
- Salt and pepper: balance and enhance all the other flavors.
Instructions
- Build the Creamy Cauliflower Sauce:
- In a soup pot, add cauliflower florets and enough water to almost cover them. Turn the heat to medium-high and cover the pot. Let it cook until the cauliflower is fork tender this usually takes about 10 to 12 minutes. The steaming soft cauliflower will become the base of your creamy sauce. Drain the water but reserve it.
- Puree the Sauce:
- Transfer the cooked cauliflower to a high-speed blender or food processor. Add olive oil, parmesan cheese, onion powder, thyme, crushed garlic, salt, pepper, and 1 cup of the reserved cooking water. Blend until thick, smooth, and creamy. This mixture will give the soup a luscious texture without needing any cream.
- Sauté Aromatics and Broccoli:
- Return to the same soup pot and melt butter over medium heat. Add the dried minced onion and sauté for about one minute allowing it to soften and release flavor without browning. Add the chopped broccoli, 2 cups of water, and Better Than Bouillon chicken base. If you prefer, use chicken broth instead of water for more depth. Simmer for 3 to 4 minutes to soften the broccoli slightly but keep some bite.
- Add Chicken and Combine:
- Add the cooked, chopped chicken to the pot and stir. Let it warm through for 1 to 2 minutes so it melds with the broccoli and broth.
- Finish the Soup:
- Pour in the creamy cauliflower mixture and stir well to combine everything. If you prefer a thinner soup, add a little more water or broth to reach your desired consistency. Allow the soup to cook on low for about 5 minutes so the flavors harmonize perfectly.

Out of all the ingredients I find that the cauliflower base is the real game changer here. It transforms simple veggies and chicken into a velvety soup that is deeply satisfying without needing cream or flour. This recipe reminds me of cozy family weekends where a big pot simmering on the stove meant laughter and warmth all around the table.
Storage Tips
Store any leftover soup in an airtight container in the fridge for up to four days. When reheating, stir in a splash of water or broth to refresh the texture. This soup also freezes well in individual portions for quick ready meals on busy days.
Ingredient Swaps
If you want to switch things up, swap broccoli for kale or spinach for a different green. Use nutritional yeast instead of parmesan for a dairy-free option. Chicken can be replaced by turkey or even firm tofu if you want to keep it vegetarian.
Serving Ideas
Serve this soup with a side of crisp keto bread or a simple salad to round out the meal. Garnish with extra parmesan or chopped fresh herbs like parsley or chives for a bright finish. A drizzle of olive oil on top adds a nice touch of richness too.

This soup hits the spot when you want something cozy but light. It’s become my go-to weeknight meal that feels like a warm hug in a bowl and I hope you enjoy it as much as my family does.
