Ingredients You’ll Need

The beauty of Zucchini Soup (Stovetop and Instant Pot) lies in its simplicity—each ingredient has a role in building layers of flavor, color, and heartiness. Here’s what you’ll need for your next unforgettable bowl of soup:

Olive oil: Adds richness and helps sautée the veggies for maximum flavor infusion.

Onion (white, yellow, or green): Provides aromatic depth and a sweet savory base.
Carrot: Lends a touch of sweetness and vibrant color to the soup.

Bell pepper (any color): Brings crunch, natural sweetness, and beautiful hues.
Zucchini or yellow squash: The star of the show—delicate, tender, and packed with subtle, fresh flavor.

Fresh tomatoes or canned diced tomatoes in tomato sauce: Give the broth a tomatoey tang and body (canned is a great shortcut in winter months).
Vegetable broth or water: The liquid base draws everything together—broth adds a bit more flavor, but water works in a pinch.
Vermicelli pasta (optional): Tiny noodles offer extra heartiness and almost melt into the soup—perfect for a little something extra.

Salt and black pepper: Essential for seasoning; adjust to your taste preferences.
Chopped parsley or dill: Adds freshness, color, and a touch of herbal brightness at the end.
Lemon juice: This last-minute squeeze finishes the soup with a burst of acidity and balance.

How to Make Zucchini Soup (Stovetop and Instant Pot)

Step 1: Prep Your Ingredients

Before you even turn on the stove or Instant Pot, it’s worth spending a few minutes to chop all your veggies and measure out your ingredients. This makes the whole cooking process smoother, so you can relax and enjoy making Zucchini Soup (Stovetop and Instant Pot) without any scrambling.

Step 2: Sauté the Base Vegetables

For both stovetop and Instant Pot methods, begin by heating olive oil in a large soup pot or directly in your Instant Pot (on Sauté mode). Add the chopped onion, carrot, and bell pepper, and cook for 2 to 3 minutes, stirring often until they’re just starting to soften. This step is where all the aromatic magic happens and lays down the flavor foundation for your soup.

Step 3: Add Broth and Remaining Veggies

Pour in the vegetable broth or water—8 cups for stovetop, or 6 cups for Instant Pot. Bring the liquid to a gentle simmer (or simply proceed on Instant Pot). Stir in the chopped zucchini and freshly diced tomatoes (or canned tomatoes, if using). The mix of summer squash and tomatoes creates a bright, colorful canvas, filling your kitchen with inviting aromas.

Step 4: Simmer or Pressure Cook

On the stovetop, let everything gently bubble away for 15 to 20 minutes, until the zucchini is tender but not mushy. If using the Instant Pot, cancel Sauté, seal the lid, and set to high pressure for 5 minutes. Allow a 5-minute natural pressure release, then finish with a quick release. Each method guarantees perfectly cooked veggies, but Instant Pot fans will love just how fast dinner comes together!

Step 5: Add Pasta (Optional)

If you want to bulk up your Zucchini Soup (Stovetop and Instant Pot), sprinkle in a handful of vermicelli pasta right at the end. For the stovetop method, cook for another 5 to 6 minutes until the pasta is just tender. In the Instant Pot, turn on Sauté and simmer for 2 to 3 minutes. This extra finishing touch makes the soup irresistibly cozy.

Step 6: Finish and Season

Take the pot off the heat and stir in the freshly chopped parsley or dill, plus a big squeeze of lemon juice. This final step brightens up the whole pot and brings all the flavors into balance. Taste and adjust with a pinch more salt and pepper if you like, and get ready to ladle up a bowl of your new favorite Zucchini Soup (Stovetop and Instant Pot).

How to Serve Zucchini Soup (Stovetop and Instant Pot)

Garnishes

A simple soup like this absolutely shines with the right toppings! Try a sprinkle of extra fresh herbs, a swirl of olive oil, a pinch of cracked black pepper, or even a handful of buttery croutons for delightful crunch. For a little heat, add a dash of red chili flakes or ground black pepper right before serving—everyone gets to customize their own bowl.

Side Dishes

Pair your Zucchini Soup (Stovetop and Instant Pot) with slices of crusty bread, a seeded roll, or crispy pita chips for dunking. A big leafy green salad tossed in lemony dressing makes a refreshing partner, too. On chillier nights, a grilled cheese sandwich or a savory scone will transform this soup into a comforting dinner feast.

Creative Ways to Present

Serve the soup in colorful bowls, or go for mini mugs as an appetizer at a dinner party—guests will be delighted by the elegant simplicity! For a bit of fun, sprinkle bowls with toasted pumpkin or sunflower seeds, or finish with a dollop of yogurt or sour cream for a creamy contrast. Presentation makes a big difference, especially with a bright and cheery recipe like Zucchini Soup (Stovetop and Instant Pot).

Make Ahead and Storage

Storing Leftovers

Store any leftover Zucchini Soup (Stovetop and Instant Pot) in a tightly sealed container in the refrigerator. The flavors deepen beautifully overnight and it will keep well for up to four days, making it a fantastic make-ahead lunch or quick dinner solution.

Freezing

This soup freezes like a dream—just let it cool completely, then pour into freezer-safe containers or bags. Leave a little space at the top for expansion, especially if you added pasta. For best texture, freeze without the pasta and add it fresh when reheating. It’ll stay delicious for up to three months!

Reheating

Warm up your Zucchini Soup (Stovetop and Instant Pot) on the stovetop over medium heat, stirring occasionally until piping hot. For single servings, the microwave works just as well—heat in 45-second bursts, stirring between each, until heated through. If the soup thickens, just add a splash of broth or water to loosen it.

FAQs

Can I use only zucchini, or mix with yellow squash?

Absolutely! Use all zucchini for a more classic flavor, or mix equal parts zucchini and yellow squash for extra color variation and a milder taste. Both work beautifully in Zucchini Soup (Stovetop and Instant Pot).

Is this soup vegan and gluten-free?

The basic Zucchini Soup (Stovetop and Instant Pot) recipe is naturally vegan if you use vegetable broth and skip the optional pasta or substitute it with a gluten-free variety. Toppings like yogurt can be swapped for dairy-free alternatives easily.

Can I add protein, such as beans or tofu?

Definitely! White beans or chickpeas add heartiness and extra nutrition. Stir in rinsed beans with the broth and simmer as directed. Silken tofu blended in or cubed tofu added at the end makes the soup creamy and protein-rich.

What other herbs can I use besides parsley or dill?

Fresh basil, cilantro, or even a touch of mint add unexpected flavor twists. Toss in whatever fresh herbs you have on hand—the soup is wonderfully versatile!

Can I blend the soup for a creamy version?

Of course! After cooking, use an immersion blender to partially or fully puree the soup right in the pot for a smooth, creamy texture. It’s especially comforting and great for little ones, too.
