Sweet Roasted Carrot Onion Soup

A roasty, toasty, and smoky carrot and onion soup that is thick and creamy in texture! This soup is a great source of protein with chicken bone broth. Simply add the ingredients to the pot, bring to a boil and add a touch of cheese for flavor. Goes great with cheesy bread to complement!

Roasty, Toasty, and Smoky!

I stumbled onto this Sweet Roasted Carrot Soup recipe last winter when I had a bag of carrots that were starting to get soft. I almost threw them out, but decided to try roasting them instead. Honestly, I wasn't expecting much—carrot soup always seemed kind of bland to me.

But when I tasted it, I was genuinely surprised. The texture was much creamier than I expected, and there was this smoky sweetness that I hadn't anticipated. It's become one of my regular weeknight dinners now, especially when it's cold outside.

The key thing I've learned is to really let the carrots and onions get golden in the oven. I used to pull them out too early, but now I wait until the edges are actually caramelized and a little charred. It makes a huge difference in the flavor—you get these sweet, smoky notes throughout the soup.

I keep the spicing pretty simple: cumin, coriander, and a bit of paprika. The cumin especially adds this warm, earthy taste that works really well with the roasted carrots. A splash of Worcestershire sauce gives it a little more depth, and I always add lemon juice at the end because it brightens everything up and keeps it from tasting too heavy.

It's the kind of soup that actually fills me up and makes me feel good afterward, not sluggish. Perfect for those nights when I want something comforting but don't want to spend too long cooking.

Who will love it?

This soup works well for family dinners during fall and winter when everyone wants something warm. It suits my health-conscious friends because it fits their dietary needs - gluten-free, paleo, and nutrient-dense - while still being satisfying.

Parents — kids will actually eat this one! Especially if you add some cheesy toast on the side. It’s naturally sweet and smooth texture means no complaints about vegetables.

This is my go-to healing soup when someone in my house is feeling under the weather. The bone broth is gentle on the stomach, and the warm spices are comforting without being overpowering.

YES you can enjoy this if you are:

  • Gluten-Free - no wheat, barley, or rye ingredients

  • Dairy-Free - uses olive oil instead of butter option

  • Paleo - all ingredients are paleo-approved whole foods

  • Whole30 Compliant - no grains, legumes, dairy, or added sugars

  • Keto-Friendly - very low in net carbs, high in healthy fats

  • Low-Carb - mainly vegetables and broth

  • Anti-Inflammatory - bone broth, turmeric-family spices, omega-rich olive oil

NO, this won’t work if you are:

  • Vegan/Vegetarian - substitute the chicken bone broth for vegetable broth instead!

The nutritional values of your preparation of this recipe are impacted by several factors, including, but not limited to, the ingredient brands you use, any substitutions or measurement changes you make, and measuring accuracy.

I like that this soup both tastes good and is nutritious. Here's what's going on:

Carrots

Each serving provides beta-carotene that converts to vitamin A, supporting vision and skin health. The fiber helps with digestion and blood sugar stability, while potassium supports heart health and vitamin K contributes to bone strength.

Onions

These contain quercetin and sulfur compounds that have anti-inflammatory properties. They also provide prebiotics that feed beneficial gut bacteria, creating a healthier digestive environment. The chromium helps your body process nutrients more efficiently.

Chicken Bone Broth

This provides collagen for joint and skin health, along with amino acids like glycine and proline that support tissue repair. The calcium, magnesium, and phosphorus contribute to bone health, and the gelatin helps maintain gut lining integrity for better nutrient absorption. It's nice when something that tastes this good also supports your health.


What you will need

  • 6-7.5 quart pot

  • Two Baking Sheets

  • Parchment Paper

  • Measuring Spoons

  • Large Capacity Blender (around 8 cups)

  • Two 48 oz Storage Containers


How to Make it Step by Step

1. Gather Ingredients

Hopefully you have extra carrots and onions on hand, because this recipe requires a lot! I use baby carrots so that I can leave them whole without chopping them up. You will also need chicken bone broth, Worcestershire sauce, lemon juice, salt, pepper, garlic, coriander, cumin, and paprika.

2. Roast the carrots in the oven

Next, you will roast the carrots in olive oil, salt, and pepper at 400 degrees for about 45-60 minutes. Roast them well! The more charred, the sweeter the soup.

3. Caramelize the onions

Next, you will caramelize the onions with the garlic and spices. Make sure the onions are nice and golden brown. They should stick to the pot at the bottom ever so slightly.

4. Put it all together: carrots, onions, chicken bone broth, Worcestershire sauce, and lemon juice

Simmer the final mixture of carrots, onions, and bone broth and spices on low heat for approximately 30 minutes or until the carrots are fork tender. I leave my pot on low for a few hours to really allow the flavors to settle in.

5. Blend it up

Transfer to a blender in batches and blend until smooth, or use an immersion blender.

6. Serve!

Dish out 1-cup servings and enjoy delicious soup that is low in calories (160 cal/cup)! This soup pairs well with different sides. I usually finish mine with a drizzle of olive oil, which adds richness, and I like to sprinkle toasted pumpkin seeds on top for a crunch. When I want to make it more filling, I serve it with warm, crusty bread for dipping.

Storage (Because You’ll Want Leftovers)

This soup stores well, which makes it practical for meal prep. After cooling completely, it keeps in the fridge for up to 4 days. The flavors develop and improve overnight.

For longer storage, it freezes well for up to 3 months. I portion it into individual containers so I can thaw single servings as needed. Just thaw overnight in the fridge, then gently reheat on the stovetop with a stir to restore the smooth texture. It reheats nicely and maintains its quality.

Ingredients

Instructions

  1. First, bake the carrots in the oven. Line parchment paper on two baking sheets and preheat oven to 400 degrees.
  2. Place baby carrots on each baking sheet and drizzle lightly with 2 tbsp of olive oil. Add salt and pepper and toss the carrots until fully covered with oil. Bake carrots in oven for approximately 45-60 min, or until browned on the edges. Remove from oven and let cool.
  3. Next, prepare the soup. Heat olive oil in pot over medium heat. Add the diced onions and cook until softened, about 5-10 minutes. Add garlic, coriander, cumin, and paprika. Cook for 5 more minutes, stirring occasionally until onions are starting to brown and caramelize.
  4. Add baby carrots, chicken bone broth, Worcestershire sauce, and lemon juice. Bring to a boil, the reduce the heat to a simmer on low. Gently scrape the bottom with a wooden spoon to clear the caramelized onions stuck to the bottom of the pot.
  5. Simmer, covered, until carrots are very fork tender, around 30 minutes.
  6. Remove from heat. Transfer to a blender in batches and blend until smooth, or use an immersion blender.
  7. Pour into airtight storage containers and keep refrigerated for up to 4 days or in the freezer for up to 3 months.

Notes

Add more paprika for smokiness. The more brown the onions and carrots, the sweeter the soup!
