👩🏻‍🍳 Why You’ll Love This Recipe

The Instant Pot makes this soup quick and effortless while concentrating flavors in a short time. It’s a great option for cool weather or anytime you want a bowl of something warm and restorative without a lot of hands-on cooking. The recipe relies on pantry staples—onions, carrots, celery, canned tomatoes and beans, potatoes, and frozen vegetables—so it’s easy to pull together with minimal shopping.

The texture is hearty from the potatoes and beans, while spinach and peas add bright color and nutrients at the end. This combination delivers a balanced, satisfying bowl that even picky eaters tend to enjoy, because the broth carries strong savory notes from garlic and dried herbs.

🥘 Ingredients Needed

• Oil – any neutral oil, such as olive or avocado oil.
• Mirepoix – onion, carrot, and celery form the aromatic base.
• Garlic – fresh minced garlic for best flavor.
• Seasoning – dried oregano, dried thyme, salt, and black pepper.
• Broth – vegetable broth to keep the soup vegetarian; chicken broth works if not vegetarian.
• Potatoes – russet or other starchy potatoes, diced to bite-sized pieces.
• Canned diced tomatoes – use diced or chopped tomatoes for acidity and body.
• Beans – navy beans are used here, rinsed and drained; other beans will work.
• Leafy greens – baby spinach is tender and quick to wilt; kale is an alternative.
• Frozen vegetables – peas and corn are added at the end for freshness and texture.

🔪 Instructions

1. Set the Instant Pot to SAUTE. Add the oil, then add the diced onion, carrot, celery, and minced garlic. Sauté for 2–3 minutes until the vegetables begin to soften and the garlic is fragrant.
2. Stir in the dried oregano, dried thyme, salt, and pepper. Sauté for another minute to bloom the spices.
3. Add the rinsed beans, diced potatoes, and the canned diced tomatoes to the pot. Stir to combine.
4. Pour in the vegetable broth, scraping any browned bits from the bottom of the pot. Ensure ingredients are evenly distributed.
5. Close the lid, set the valve, and pressure cook on HIGH for 5 minutes. Note: the pot will take 15–20 minutes to come up to pressure before the timed cook begins.
6. When cooking completes, perform a quick release or allow a brief natural pressure release if you prefer. Carefully remove the lid.
7. Add the chopped spinach, frozen peas, and corn to the soup and stir until the spinach wilts and the frozen vegetables are heated through.
8. Adjust seasoning to taste and serve immediately. Garnish with fresh herbs such as parsley or basil if desired.

💭 Other Helpful Tips

• To save prep time, use frozen diced onions, diced carrots, and frozen diced potatoes.
• Either canned or frozen peas and corn work fine; add them at the end so they stay tender and bright.
• Swap or supplement navy beans with chickpeas, black beans, or pinto beans for variety and extra protein.
• Leftovers keep well in an airtight container in the refrigerator for up to 5 days.
• Remember that the 5-minute cook time refers to pressure cooking only; allow for the time it takes the Instant Pot to reach pressure when planning.
• If you prefer a thicker broth, mash a small portion of the potatoes and beans into the soup, or remove a cup, mash, and return it to the pot.

📖 Variations

• Swap navy beans for black beans, pinto beans, or lentils for a different flavor and texture.
• Add extra vegetables such as zucchini, broccoli, or cauliflower for more variety and nutrients.
• Replace spinach with kale or other hearty greens; if using kale, remove tough stems and add a few minutes earlier if you like it very tender.
• Use fire-roasted diced tomatoes for a smoky flavor profile.

🥗 Suggested Side Dishes

This vegetable soup pairs well with crusty bread, garlic toast, a simple green salad, or roasted vegetables. A slice of toasted sourdough or a warm whole-grain roll makes the meal more filling and enjoyable.
