This sweet potato bisque with cinnamon toast croutons is anything but ordinary. It’s rich, creamy, and full of flavor, yet still simple to make.
I use bacon and a splash of bourbon, and they make all the difference. The bourbon adds depth and a subtle complexity, while the bacon brings richness and a salty crunch that finishes the soup beautifully.
It’s a hearty, satisfying soup that’s perfect for cold days when you want something warm and comforting. I love serving it as a starter for dinner parties or over the holidays—it feels a little special without being fussy. Plus, it’s easy to make ahead, which makes entertaining that much simpler.

Sweet Potato Bisque with Cinnamon Croutons
Ingredients
- 4 strips bacon
- 1 medium onion (chopped)
- 4 cloves garlic (minced)
- ¼ teaspoon chili flakes
- ¼ cup bourbon (optional)
- 6 cups chicken stock (can sub vegetable stock)
- 1 teaspoon EACH: sea salt and black pepper (more to taste)
- 4 medium sweet potatoes (peeled and chopped)
- 1 cup heavy cream
Cinnamon Toast Croutons
- 4 slices bread (crusts cut off and cut into squares)
- 1 tablespoon butter (melted)
- 2 teaspoons cinnamon sugar (see notes)
Instructions
- Add the bacon to a large soup pot over medium heat and cook until it is crispy, about 12 minutes. Remove it from the pot and crumble it when it is cool enough to touch.4 strips bacon
- If there is less than 2 tablespoons of bacon oil in the pot, add some olive oil. If there is more, remove it. Add the onion to the pot and saute it over medium heat until it starts to brown, about 5 minutes. Add the garlic and red chili flakes and cook for one minute more. If using, add the bourbon to the pot and scrape the bottom to remove any stuck-on bits.1 medium onion, 4 cloves garlic, ¼ teaspoon chili flakes, ¼ cup bourbon
- Add the stock, sweet potatoes, salt, and pepper, and bring the pot to a boil. Reduce the heat and simmer for 20 minutes, or until the sweet potatoes are soft.6 cups chicken stock, 4 medium sweet potatoes, 1 teaspoon EACH: sea salt and black pepper
- While the soup is simmering, make the croutons. Preheat your oven to 400 degrees. Pile the bread cubes on a baking sheet, drizzle them with the melted butter, and cinnamon sugar and then use your hands to mix it well so that the bread is evenly coated. Bake for 15-20 minutes, until the croutons are crispy. They will crisp more as they cool.4 slices bread, 1 tablespoon butter, 2 teaspoons cinnamon sugar
- When the sweet potatoes are soft, puree the soup either with an immersion blender or in batches using a regular blender. If you don't have a high-speed blender and you want a super smooth soup, you can pass the soup through a fine-mesh sieve.
- Stir the cream into the soup and gently reheat it – don't let it boil. Taste the soup and add more salt and pepper, as wanted. Serve the soup topped with the crispy bacon and croutons.1 cup heavy cream

You don’t indicate in your recipe what to do to prep the sweet potatoes. Should I peel them? Should I boil them first? Should I cube them? Chop them? Dice them? What? What? what? Please help!!!
Thank you for pointing that out! Peeled and chopped. 🙂
This was insane! Those cinnamon croutons were even better than I thought they’d be. Went really well with the soup.
