Ingredients

For 2-3 servings:

  • 1 large garnet sweet potato
  • 1 large yellow onion
  • 5-6 large garlic cloves
  • 7-10 sprigs fresh thyme (approximately 1 tablespoon chopped)
  • 3 cups chicken or vegetable broth
  • ½ cup canned coconut milk or heavy whipping cream
  • 2 tablespoons ghee, extra virgin olive oil, or refined coconut oil (plus 1-2 tablespoons for roasting)
  • 2 scoops collagen powder (optional)
  • 1 tablespoon nutritional yeast
  • 1-2 teaspoons salt (adjust based on broth sodium content)
  • 2 large canned or jarred bell peppers (optional)
  • Freshly grated nutmeg to taste (avoid pre-ground)
  • Small dash of cinnamon (optional)

Instructions

  1. Preheat your oven to 400°F (200°C) and begin by washing all vegetables and herbs.
  2. Peel and cut sweet potatoes and onion into medium/large dice. Keep them roughly the same size for even cooking.
  3. Toss the diced vegetables separately with ghee or oil of choice and arrange on a sheet pan, keeping them somewhat separated for even browning.
  4. Place the pan in the preheated oven and begin roasting for 20 minutes.
  5. Meanwhile, prepare the garlic: Using the flat side of your knife, press down on each clove to loosen the skin. Remove skins and place garlic on a piece of aluminum foil. Drizzle with oil or ghee, then wrap tightly in the foil. Add this packet to your sheet pan of roasting vegetables.
  6. While vegetables roast, strip thyme leaves from stems and add to your blender.
  7. Once vegetables are completely tender and lightly caramelized, transfer all ingredients except salt and nutmeg to a high-speed blender.
  8. Blend until perfectly smooth, then taste and adjust seasoning with salt and freshly grated nutmeg. Add more cream or coconut milk if desired for richness.

Storage & Freezing Tips

This soup is perfect for meal prep and freezes beautifully. For best results:

  • Portion into individual servings before freezing
  • Use coconut milk instead of cream if planning to freeze
  • Defrost overnight in the refrigerator
  • Reheat gently on stovetop over low heat, covered, stirring occasionally

Chef's Notes

The key to this soup's exceptional flavor lies in roasting the vegetables, which concentrates their natural sugars and adds depth. Fresh nutmeg makes a remarkable difference - its warm, complex aroma elevates the sweet potato's natural sweetness while adding sophistication to the final dish.

The addition of collagen not only boosts the nutritional profile but also contributes to a silky-smooth texture. Combined with the natural beta-carotene from sweet potatoes and the anti-inflammatory properties of garlic and herbs, this soup is as nutritious as it is delicious.

Remember that while both cream and coconut milk work beautifully in this recipe, coconut milk is the better choice if you're planning to freeze portions for later enjoyment. It maintains its smooth, creamy texture better through the freezing and reheating process.

Whether you’re looking for an easy potato soup recipe, a potato soup recipe that’s full of nutrients, or a creamy collagen broth-based dish, this sweet potato soup checks all the boxes. Cozy, nourishing, and simple to make—give this recipe a try and enjoy the benefits of sweet potatoes in every spoonful!
