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!

The best part about this soup is the roasty, sweet depths of flavor combined with a thick and creamy texture. The key to getting the right flavor is allowing the onions and carrots to roast into caramelization.

Yes, even the carrots should be a bit charred to really get the smoky notes throughout the soup.

Adding to the flavor is the Worcestershire sauce (don’t skip!) and the spices: cumin, coriander, and paprika.

This smoky soup reminds me of lounging by a fire and brings me warmth and comfort when the cold hits.

Nutritional information is provided as a courtesy only, and is not to be taken as medical information or advice. 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.

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 in a dutch oven or soup pot over medium-high heat for 10-15 minutes. Make sure the onions are nice and brown!

Tip: a dash of white wine will help remove the onions stuck to the bottom of the pot, and will add a brightness to the flavor!

4. Put it all together

Add the roasted carrots, chicken bone broth, Worcestershire sauce, and lemon juice and bring to a boil over medium-high heat. Reduce the heat to low and simmer for approximately 30 minutes or until the carrots are fork tender. I leave my pot on low for a few hours to allow the flavors to settle in.

5. Blend it up

Remove from heat and let soup cool for 10-15 minutes. Transfer to a blender in batches and blend until smooth, or use an immersion blender. Make sure to vent the blender to let out the pressure from the heat!

6. Serve!

Dish out 1-cup servings and enjoy delicious soup that is low in calories!

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.
