Whether you’re meal prepping for the week or craving a quick lunch, this soup delivers on both nutrition and satisfaction. The recipe scales effortlessly, so you can make a single serving or a batch for leftovers. Here’s how to create it—without compromising on taste.

Ingredients for 100 calorie soup

Bold flavors, light ingredients—this soup delivers restaurant-quality taste with just 100 calories per serving.

The broth is your flavor foundation—homemade or high-quality store-bought makes all the difference. I always grab Pacific Foods or Imagine from the store, but homemade is even better. For the zucchini, medium-sized works best—it’s mild enough to not overpower but adds satisfying texture. The mushrooms? Cremini or white are ideal, but shiitake adds depth if you want to splurge. Fresh ginger and garlic are non-negotiable here—they’re what give this soup its bright, aromatic punch. Costco or Trader Joe’s usually have good prices on fresh ginger, and I always grab extra since it keeps well in the freezer.

No fresh ginger? Ground ginger at half the amount works in a pinch, but it lacks the zing. Swapping white beans for chickpeas? Same quantity—they’re almost identical in texture and protein. The Greek yogurt is where the magic happens—non-fat, plain is key to keep calories low. If you’re vegan, unsweetened coconut yogurt works perfectly. For the veggies, baby carrots or regular both work—just slice them thin so they cook down nicely. And if you’re short on time, frozen spinach (thawed and drained) is a great shortcut.

This soup tastes even better the next day—4-5 days in the fridge is perfect for meal prep. For longer storage, freeze for up to 3 months—just reheat gently on the stove. I like to portion it into glass containers so I can grab and go. The yogurt adds a creamy finish, but if you’re sensitive to dairy, add it at the end so it doesn’t curdle during cooking. And trust me, the parsley isn’t just for looks—toss it in at the very end for that fresh, vibrant finish.

Step-by-step instructions for lightweight, flavor-packed soup

Here’s how to transform simple ingredients into a vibrant, nutrient-rich soup that clocks in at just 100 calories per serving.

Heat the 1 tablespoon olive oil in a large pot over medium heat. Add the 0.5 whole yellow onion and 0.5 lb carrots, cooking for 5-6 minutes until the onions become translucent and the carrots begin to soften. You’ll know they’re ready when they release their sweet aroma—this is your flavor foundation.

Add the 4 cloves garlic cloves and 1 tablespoon fresh ginger, stirring constantly for 30 seconds until fragrant. Here’s the thing—don’t let the garlic burn. It should smell heavenly but not bitter. The ginger will add that bright, zesty kick that balances the earthy vegetables perfectly.

Increase heat to medium-high and add the 1.5 lb zucchini and 0.5 lb mushrooms, stirring occasionally for 4-5 minutes until the zucchini begins to soften slightly. The mushrooms will release their moisture, creating a rich, umami base. You want them to brown just a little at the edges—that’s where all the flavor hides.

Stir in the 1 cup canned white beans and 4 cups low-sodium chicken broth, bringing everything to a gentle boil. Once boiling, reduce heat to medium-low and let it simmer uncovered for 10 minutes. This gives the vegetables time to meld together while the broth infuses with their flavors. The beans will help thicken the soup naturally without adding many calories.

After the initial simmer, stir in the 2 cups baby spinach and 1 tablespoon lemon juice. The spinach will wilt dramatically in just 1-2 minutes—that’s your cue to remove the pot from heat. The lemon juice brightens everything up, cutting through the richness of the vegetables and adding a refreshing finish. I know it seems like a small amount, but trust me, it makes all the difference.

Season with the 0.5 teaspoon salt and 0.25 teaspoon ground black pepper, tasting as you go. Remember, the broth is low-sodium, so you’ll need to adjust the seasoning carefully. The yogurt will add creaminess later, so don’t over-salt now.

Let the soup cool slightly for 5 minutes until it’s warm but not scalding. Stir in the 0.25 cup plain non-fat Greek yogurt until fully combined. This adds a luxurious creaminess without the calories of heavy cream. The yogurt also helps stabilize the soup’s texture, preventing it from becoming watery as it cools.

Real talk: If you’re serving this immediately, the yogurt will blend seamlessly. But if you’re prepping ahead, let it cool completely before adding the yogurt to prevent curdling. The final touch is the 0.25 cup fresh parsley, which adds freshness and a pop of color. Stir it in just before serving so it stays vibrant.

Serving suggestions for this recipe

Garnish Like a Pro

Fresh herbs elevate this soup instantly—try chopped cilantro or thyme sprigs for a different twist. I like to add crispy fried shallots (tossed in 1 tsp olive oil and fried for 2-3 minutes at 350°F) for a gourmet touch.

For extra crunch, top with toasted pumpkin seeds (roast 2 tbsp seeds with ½ tsp smoked paprika at 300°F for 8-10 minutes). 🌿

Bread Pairings

Serve with whole-grain crackers or rye toast for a satisfying bite. I love Trader Joe’s Everything Bagel Seasoning sprinkled on toasted bread—it adds a salty, herby contrast. For a lighter option, use gluten-free rice crackers (like Mary’s Gone Crackers) to keep calories in check.

Warm the bread slightly before serving so it soaks up the broth beautifully.

Protein Boosters

Add grilled shrimp (sauté 4 oz shrimp in 1 tsp olive oil for 2 minutes per side) or poached chicken breast (simmer 3 oz chicken in broth for 12 minutes) for extra protein.

For a vegan option, stir in ½ cup cooked quinoa or ½ cup lentils (cook ¼ cup dry lentils in 1 cup water for 20 minutes). These additions keep the soup under 150 calories per serving while adding heartiness.

Meal Prep Serving Ideas

Portion into glass meal prep containers with bamboo or stainless steel lids for easy grab-and-go lunches. I like to layer the soup with a small side of hummus (store-bought or homemade) and sliced cucumbers for a balanced meal.

For a cozy vibe, serve in mugs with a spoon—perfect for chilly days. Label containers with dates to track freshness (this soup stays fresh for 4-5 days in the fridge).

Dietary Adaptations

For a vegan version, swap the Greek yogurt for unsweetened coconut yogurt and use vegetable broth. Add 1 tsp nutritional yeast for a cheesy flavor. For gluten-free, ensure your broth is certified gluten-free (like Pacific Foods GF Chicken Broth) and use GF crackers.

For low-carb, reduce the beans to ½ cup and add ½ cup diced cauliflower instead. Each adaptation keeps the soup under 100 calories per serving while fitting dietary needs.

Seasonal Twists

In summer, add diced cucumber and mint leaves for a refreshing twist. For fall, swap zucchini for butternut squash (roast ½ cup cubes at 400°F for 20 minutes before adding).
