One-Pot Cooking Instructions

1. Melt the butter in a large pot over medium heat until bubbly.
2. Add diced onion, chopped carrots, and chopped celery with a pinch of salt and pepper; increase heat to medium-high and cook, stirring occasionally, until onions are translucent, about 10 minutes.
3. Reduce heat to medium and stir in minced garlic, dried oregano, dried thyme, and dried sage; cook 1 minute, stirring.
4. Sprinkle in the flour and cook, stirring frequently, about 1 minute to coat the vegetables.
5. Pour a splash of vegetable broth into the pot to deglaze, scraping up browned bits from the bottom.
6. Stir in diced potatoes, drained corn, chopped broccoli, and the remaining vegetable broth; season with salt and pepper.
7. Cover the pot, increase heat to medium-high, and bring to a simmer.

8. Once simmering, reduce heat to low, keep covered, and cook 10–12 minutes until potatoes are fork-tender, stirring occasionally.

9. Optional: before adding dairy, blend half or all of the soup with an immersion blender or regular blender for a smoother, creamier texture.
10. Remove the pot from the heat and stir in the heavy cream, shredded sharp cheddar, and a splash of balsamic vinegar.
11. Stir until the cheese melts and the soup is smooth; garnish with chopped parsley, extra shredded cheddar, and oyster crackers.

Pro Tips for Perfect Soup

• Use whatever veggies you have on hand! This creamy vegetable soup is super flexible. I love making a big batch when I need to clean out the fridge. Just keep a similar veggie ratio and the soup will turn out delicious every time.
• Want it extra creamy? Before stirring in the cream and cheese, try blending half or all of the soup with an immersion blender or regular blender. Then finish with the cream and cheddar for a silky smooth texture.

Easy Swaps and Add-Ins

Here are some easy swaps and add-ins to tailor this creamy vegetable soup to your tastes or dietary needs.

• Swap the vegetables: Try cauliflower, zucchini, peas, green beans, or bell peppers instead of some or all of the broccoli and corn. Add tender greens like spinach or kale near the end for a fresh pop of color.
• Try different potatoes: Russets or red potatoes work well, or use sweet potatoes for a slightly sweeter, earthier flavor. Just note sweet potatoes may cook faster.
• Change up the cheese: Smoked Gouda, Gruyère, Monterey Jack, or pepper jack are all flavorful alternatives. For a lighter soup, skip the cheese altogether.
• Make it dairy-free or vegan: Swap butter for olive oil or vegan butter, replace heavy cream with canned coconut milk, cashew cream, or plant milk plus a cornstarch slurry to thicken, and use vegan cheese or nutritional yeast for cheesy flavor.
• Gluten-free options: Use a gluten-free flour blend instead of all-purpose flour, or thicken at the end with a cornstarch slurry (1-2 tablespoons cornstarch mixed with cold water).
• Add protein: Stir in cooked chickpeas or cannellini beans to keep it vegetarian, or add cooked shredded chicken, diced ham, or sausage if you want meat.
• Seasoning adjustments: Use Italian seasoning instead of the dried herbs, or add smoked paprika, red pepper flakes, or chipotle in adobo for a smoky kick. A squeeze of lemon juice or splash of white wine vinegar brightens things up too.
• Corn options: Fresh corn cut off the cob adds sweetness, or roast corn kernels beforehand for a caramelized flavor boost.
• Toppings: Try dollops of sour cream or Greek yogurt, chopped fresh herbs, crunchy croutons, or tortilla strips instead of oyster crackers for variety.

Storage, Freezing, and Reheating

• Make Ahead: This creamy vegetable soup is great for meal prep. I often make a big pot on Sunday and enjoy it for lunches all week. You can also chop up all the veggies a day or two ahead—just keep the potatoes submerged in water so they don’t brown.
• Storage: Keep leftovers in an airtight container in the fridge for up to 5 days.
• Freezing: Freeze the soup in an airtight container for up to 3 months. It’s perfect for a quick, comforting meal anytime.

• Reheating: Thaw frozen soup overnight in the fridge, then warm it gently in a saucepan over medium heat. Stir occasionally until hot, adding salt and pepper to taste before serving.
