What You’ll Need
- 2 tablespoons butter (or ghee)
- 1 tablespoon olive oil
- 1 medium onion, finely diced
- 4 cloves garlic, minced
- 4 cups low-sodium chicken broth
- 1 cup heavy cream
- 4 ounces cream cheese, softened and cubed
- 1 1/2 pounds cooked chicken, shredded or chopped (rotisserie works great)
- 3/4 cup freshly grated Parmesan cheese (plus more for serving)
- 1 teaspoon Italian seasoning
- 1/2 teaspoon garlic powder (optional for extra garlic flavor)
- 1/4 teaspoon nutmeg (classic for Alfredo)
- Salt and black pepper, to taste
- 2 cups fresh baby spinach (optional)
- 1 1/2 cups cauliflower florets or riced cauliflower (optional for more body)
- 2 tablespoons chopped fresh parsley, for garnish
- Red pepper flakes, to taste (optional)
How to Make It
- Warm a large pot over medium heat. Add butter and olive oil.
When the butter melts, add the diced onion and a pinch of salt. Cook 4–5 minutes until softened and translucent.
- Add the minced garlic. Stir for 30 seconds, just until fragrant.
Don’t let it brown.
- Pour in the chicken broth. Bring to a gentle simmer. If using cauliflower florets, add them now and simmer 6–8 minutes until tender.
- Reduce heat to medium-low.
Stir in the heavy cream and cream cheese. Whisk gently until the cream cheese fully melts and the broth looks creamy and smooth.
- Add shredded chicken, Italian seasoning, garlic powder, nutmeg, and a few grinds of black pepper. Simmer 5 minutes, stirring occasionally.
- Lower the heat to avoid boiling.
Sprinkle in the Parmesan a little at a time, stirring as you go. Let it melt before adding more to prevent clumping. Taste and season with salt as needed.
- If using spinach or riced cauliflower, stir it in now.
Simmer 2–3 minutes until the spinach wilts and the soup slightly thickens.
- Adjust consistency. For thicker soup, simmer uncovered a few extra minutes. For thinner soup, add a splash of broth or cream.
- Finish with chopped parsley and a pinch of red pepper flakes if you like heat.
Serve hot with extra Parmesan on top.
How to Store
- Refrigerator: Cool completely, then store in airtight containers for up to 4 days.
- Freezer: Cream-based soups can separate after freezing, but this one does fine if you reheat gently. Freeze up to 2 months. Thaw overnight in the fridge.
- Reheating: Warm on the stove over low heat, stirring often.
Add a splash of broth or cream if it thickens too much. Avoid boiling to keep the dairy smooth.
Why This is Good for You
- Low-carb, high-fat balance: Ideal for keto or low-carb lifestyles, helping stabilize energy and reduce cravings.
- Protein-packed: Chicken supports muscle maintenance and helps you feel full longer.
- Electrolyte-friendly: Broth adds sodium and minerals, which can be helpful on keto.
- Nutrient adds: Spinach brings fiber, folate, and vitamin K; cauliflower adds extra fiber and volume without the carbs.
What Not to Do
- Don’t boil after adding cream and cheese. High heat can cause curdling or a grainy texture.
- Don’t add all the Parmesan at once. Sprinkle gradually so it melts smoothly.
- Don’t skip salting in layers. Season the onions, then the soup. It builds balanced flavor without over-salting.
- Don’t use pre-shredded Parmesan if you can help it. Freshly grated melts better and tastes cleaner.
- Don’t overcrowd with too many add-ins. Keep it focused so the Alfredo flavor shines.
Variations You Can Try
- Broccoli Alfredo Soup: Swap the spinach for small broccoli florets.
Simmer until tender.
- Mushroom Alfredo Soup: Sauté 8 ounces of sliced mushrooms with the onions for deep, savory flavor.
- Bacon and Chicken Alfredo Soup: Crisp 4 slices of bacon first. Use the bacon fat with butter for the onions, then crumble the bacon on top.
- Creamy Pesto Twist: Stir in 2 tablespoons of pesto before serving for a fresh, herby kick.
- Roasted Garlic Upgrade: Swap minced garlic for a whole head of roasted garlic for sweeter, mellow depth.
- Dairy-Light Version: Use half heavy cream and half unsweetened almond milk, and reduce Parmesan to 1/2 cup. Texture will be lighter but still creamy.
- Spicy Alfredo: Add 1/2 teaspoon crushed red pepper flakes with the Italian seasoning.
FAQ
Can I make this with raw chicken?
Yes.
Dice chicken breasts or thighs and sauté them in the pot with a little oil and salt until cooked through, then remove and proceed with the recipe. Add the cooked chicken back in after the cream cheese melts.
What’s the best way to avoid grainy cheese?
Keep heat low, add Parmesan gradually, and stir continuously. Using freshly grated cheese and avoiding a hard boil makes the texture silky.
Can I make it without cream cheese?
You can.
The soup will be slightly less thick. Add an extra 1/4 cup Parmesan and simmer a bit longer, or blend a cup of the soup with cooked cauliflower and stir it back in for body.
Is this gluten-free?
Yes, as written it contains no flour. Always check your broth and cheese labels to be sure they’re gluten-free.
How many carbs per serving?
It varies based on brands and add-ins, but a typical serving lands around 5–7 net carbs without cauliflower or spinach.
Use a nutrition calculator with your exact ingredients for precise numbers.
Can I use coconut milk instead of cream?
Full-fat coconut milk works in a pinch, but it will change the flavor. If you try it, balance with extra Parmesan and a pinch more salt.
What can I serve with it?
A simple green salad with a zesty vinaigrette is perfect. For a heartier meal, add roasted broccoli or a side of garlicky sautéed zucchini.
