Last January, after weeks of holiday indulgence left me feeling sluggish and heavy, I found myself craving something vibrant and alive. This rainbow soup emerged from that kitchen moment when I simply threw every colorful vegetable I could find into a pot. The way the broth turned this incredible jewel-toned magenta from the beets felt like magic happening right on my stove.

I first made this for my sister who was recovering from a nasty flu, and she swore it was the most healing thing shed eaten. Later that same week, I doubled the recipe and took some to work where even my skeptical coworkers kept coming back for seconds. Something about that combination of earthy beets, sweet carrots, and bright herbs just speaks to people.

Instructions

Start your aromatic base:
Heat olive oil in your large pot over medium heat and add onion and garlic, stirring until they soften and fill your kitchen with the most incredible fragrance
Add the root vegetables first:
Beetroot and carrots need the most time so toss them in and let them sauté for about 5 minutes until they start to glisten
Add the quicker cooking vegetables:
Throw in courgette, tomatoes and bell pepper and cook for another few minutes until everything smells amazing
Create the broth:
Pour in vegetable broth and watch as it turns this gorgeous pink color, then bring to a boil
Let it simmer slowly:
Reduce heat, cover and let everything get tender for 20-25 minutes while your house fills with nourishing smells
Finish with brightness:
Stir in fresh herbs, lemon juice, salt and pepper and taste as you go until it is perfect
Serve with love:
Ladle into bowls and maybe add extra herbs on top because this soup deserves to look as good as it tastes

Making It Your Own

Sometimes I add a can of chickpeas or lentils if I want it to be more filling for dinner. You could also throw in some spinach or kale in the last five minutes for extra green goodness.

Serving Suggestions

A slice of toasted whole grain bread is perfect for dunking into all those colorful juices. If you are serving this to guests, a drizzle of good olive oil on top looks beautiful.

Storage And Meal Prep

This soup keeps beautifully in the refrigerator for up to five days and actually gets better as the flavors develop. It freezes well too so I often make a double batch.

  • Store in airtight containers and leave space at the top because liquid expands when freezing
  • Thaw overnight in the refrigerator and reheat gently on the stove
  • The fresh herbs are best added after reheating so they stay bright and flavorful
