Shopping List
- Butter or ghee
- Olive oil (optional, for sautéing)
- Yellow onion, finely chopped
- Garlic, minced
- Chicken broth or vegetable broth (low-sodium)
- Heavy cream (or full-fat coconut cream for dairy-light variation)
- Cream cheese, softened
- Fresh spinach (or frozen chopped spinach, thawed and well-drained)
- Cheese, shredded: Gruyère, sharp cheddar, or a blend
- Parmesan, grated
- Ground nutmeg
- Salt and black pepper
- Red pepper flakes (optional)
- Lemon juice (optional, for brightness)
Instructions
- Sauté the aromatics. Heat 1 tablespoon butter (and a drizzle of olive oil if you like) in a medium pot over medium heat. Add the chopped onion and a pinch of salt.
Cook 4–5 minutes until translucent. Stir in minced garlic and cook 30 seconds until fragrant.
- Add broth and simmer. Pour in 3 cups of chicken or vegetable broth. Bring to a gentle simmer for 5 minutes to let flavors develop.
- Wilt the spinach. Add 6–8 cups of fresh spinach (or about 10 ounces frozen, well-drained).
Stir until wilted, 2–3 minutes. If using frozen, cook a bit longer to remove excess moisture.
- Blend to your preferred texture. For a smoother soup, use an immersion blender right in the pot. For some texture, blend only half or skip blending entirely.
Keep heat on low.
- Stir in cream and cream cheese. Add 1 cup heavy cream and 4 ounces softened cream cheese. Whisk or stir until fully melted and smooth. Keep the soup just below a simmer to prevent curdling.
- Add the cheeses. Sprinkle in 1 to 1½ cups shredded cheese (Gruyère or sharp cheddar) and 1/3 cup grated Parmesan.
Stir slowly until melted and silky. If it seems too thick, add a splash of broth.
- Season. Add 1/8 teaspoon nutmeg, black pepper to taste, and more salt if needed. A pinch of red pepper flakes adds gentle heat.
A squeeze of lemon brightens the flavors.
- Adjust and serve. Taste and adjust seasoning. Ladle into bowls and garnish with a little extra Parmesan, cracked pepper, or a drizzle of olive oil.
Keeping It Fresh
- Storage: Cool the soup, then refrigerate in an airtight container for up to 4 days. It may thicken—thin with broth when reheating.
- Freezing: This soup can freeze for up to 2 months, but dairy can slightly separate.
Reheat gently and whisk to bring it back together.
- Reheating: Warm over low heat, stirring often. Avoid boiling once the cheese and cream are in to prevent graininess.
- Meal prep: Portion into single-serve containers for easy lunches. Keep toppings like bacon crumbles or extra cheese separate.
Benefits of This Recipe
- Keto-friendly macronutrients: High in fat, moderate in protein, and very low in carbs.
- Vegetable-forward: A tasty way to pack in greens without feeling like you’re eating a salad.
- Comfort with control: Satisfies cravings for creamy soups while keeping sugar and starches low.
- Budget friendly: Uses everyday ingredients and can be stretched with extra broth or spinach.
- Flexible flavors: Works with many cheeses and add-ins, so you can adapt to what you have.
What Not to Do
- Don’t boil after adding dairy. High heat can cause the cheese and cream to separate or turn grainy.
- Don’t skip salting in stages. Season the onions, the broth, and the final soup.
It builds balanced flavor.
- Don’t add cheese all at once. Sprinkle it in gradually, stirring, so it melts smoothly.
- Don’t use watery spinach. If using frozen, squeeze it dry. Extra water thins the soup and dulls flavor.
- Don’t over-blend with hard cheese already added. Blend before adding cheese to avoid gummy texture.
Alternatives
- Dairy-light version: Use coconut cream instead of heavy cream and reduce cheese by half. Add nutritional yeast for cheesy flavor without extra carbs.
- Cheese swaps: Try Gouda, Fontina, or Monterey Jack.
For sharper bite, use aged cheddar plus Parmesan.
- Protein boosts: Add shredded rotisserie chicken, cooked bacon, or browned sausage. Stir in at the end.
- Vegetable add-ins: Mushrooms, zucchini, or broccoli florets work well. Sauté before adding broth.
- Herb variations: Fresh thyme, chives, or parsley add freshness.
A little smoked paprika gives a cozy, smoky note.
- Thicker or thinner: For thicker soup, add extra cream cheese or simmer a few minutes. For thinner, loosen with broth.
FAQ
Is this soup really keto?
Yes. It’s built around low-carb ingredients like spinach, cream, and cheese.
Keep an eye on the onion amount and use low-sodium, no-sugar-added broth to maintain low net carbs.
Can I use frozen spinach?
Absolutely. Thaw it first and squeeze out as much water as possible. You may need a bit less broth since frozen spinach can release extra moisture.
How do I prevent the cheese from clumping?
Keep the heat low, add cheese gradually, and stir constantly.
Using room-temperature cream cheese and shredding your own cheese helps it melt smoothly.
Can I make it without cream cheese?
Yes. Replace with more heavy cream or mascarpone, or blend in a small amount of riced cauliflower to thicken without extra dairy.
What can I serve with it?
Keto-friendly sides like a leafy salad, almond flour biscuits, or roasted veggies pair nicely. A few bacon crumbles or a soft-boiled egg on top also works well.
How long does it keep?
It keeps up to 4 days in the fridge and up to 2 months in the freezer.
