Roasted Vegetable Soup is one of my favorite cold-weather comfort foods that turns simple ingredients into something truly special. The secret lies in roasting the vegetables first, which creates deep caramelized flavors and a subtle smokiness that you just can’t get from boiling. This creamy soup is incredibly satisfying and perfect for cozy nights at home.
I still remember the first time I made roasted vegetable soup on a particularly chilly evening. I had a bunch of root vegetables sitting in my pantry, and instead of making a regular soup, I decided to roast them first. The difference was amazing! The roasting process brought out natural sweetness and added layers of flavor I never expected. Now, this roasted veggie soup has become my go-to recipe whenever I crave something warming and wholesome. It’s smooth, creamy, and customizable based on whatever vegetables you have on hand. The best part? Your kitchen will smell wonderful while those veggies caramelize in the oven.

What You’ll Need for This Roasted Vegetable Soup
Before you start, let me share a helpful tip: I always cut my vegetables into similar-sized chunks so they roast evenly. This prevents some pieces from burning while others stay undercooked. Here’s everything you need:
- 2 medium sweet potatoes, peeled and chopped into 1-inch chunks
- 2 medium onions, quartered (I prefer yellow or sweet onions for extra flavor)
- 3 large carrots, peeled and chopped into 1-inch pieces
- 2 medium parsnips or other root vegetables like turnips, chopped
- 2-3 whole garlic cloves, unpeeled (roasting them with the skin on makes them sweet and mild)
- 2-3 fresh rosemary sprigs
- 3-4 tablespoons olive oil for roasting
- Salt and black pepper to taste (be generous!)
- 4 cups vegetable stock or chicken stock, plus more as needed
- 1/2 cup single cream or heavy cream
- Optional: fresh herbs like parsley or chives for garnish
Pro tip: I recommend using two baking trays if your vegetables look crowded. Overcrowding causes steaming instead of roasting, and you’ll miss out on those beautiful caramelized edges that make this roasted vegetable soup so flavorful.
How I Make This Creamy Roasted Vegetable Soup
I prefer prepping all my vegetables before turning on the oven. It makes the process smoother and more enjoyable. Here’s my step-by-step method:
Step 1: Preheat your oven to 200°C (400°F). While it heats up, prepare your vegetables.
Step 2: Arrange the sweet potatoes, onions, carrots, parsnips, and whole unpeeled garlic cloves on a large baking sheet. Nestle the rosemary sprigs among the vegetables. Don’t peel the garlic yet. Roasting it in the skin makes it incredibly sweet and soft.
Step 3: Drizzle with 3-4 tablespoons olive oil, then season very well with salt and black pepper. Use your hands to toss everything together, making sure each piece is thoroughly coated. This step is crucial for developing those deep roasted flavors in your roasted vegetable soup.
Step 4: Pop the tray in the oven for 25 minutes. After 25 minutes, give everything a good stir to ensure even browning, then return to the oven for another 20-25 minutes. You’re looking for nicely caramelized edges and fork-tender vegetables. The onions should be golden, and the sweet potatoes should have some crispy bits. Total roasting time is 45-50 minutes.
Step 5: Remove the rosemary sprigs and discard them. Peel the skin from the roasted garlic cloves (they should slip right off). Transfer all the roasted vegetables to a deep saucepan and add 4 cups of stock.
Step 6: Use an immersion blender to blend everything until completely smooth and creamy. If using a regular blender, work in batches and be very careful with the hot liquid. Allow steam to escape by removing the center cap and covering with a kitchen towel to prevent pressure buildup. Blend until there are no chunks remaining.
Step 7: Once smooth, stir in the cream and taste the soup. Adjust seasoning with more salt and pepper if necessary. If the soup is too thick, add more stock a little at a time until you reach your desired consistency. Heat gently until warmed through, then serve and enjoy!
Common mistake to avoid: Don’t rush the roasting process. If your vegetables aren’t caramelized enough, your roasted vegetable soup will taste flat. Those golden-brown edges are where all the flavor lives!
Perfect Pairings for Roasted Vegetable Soup
This soup tastes wonderful on its own, but the right sides can turn it into a complete meal.
Crusty Sourdough Bread: Nothing beats tearing off chunks of warm, crusty bread to dip into this creamy roasted vegetable soup. The tangy sourdough complements the sweet roasted vegetables perfectly.
Simple Green Salad: A light arugula or mixed greens salad with lemon vinaigrette adds freshness and balances the richness of the soup. It’s also a great way to sneak in more vegetables.
Grilled Cheese Sandwich: For ultimate comfort food, pair your roasted vegetable soup with a classic grilled cheese. The crispy, buttery sandwich alongside the smooth soup is an unbeatable combination.
Roasted Chickpeas: Sprinkle some crispy roasted chickpeas on top for added protein and a delightful crunchy texture contrast.

Storing Your Roasted Vegetable Soup
This soup stores beautifully, making it perfect for meal prep. Let the soup cool completely, then transfer it to airtight containers. It will keep in the refrigerator for up to 3 days. The flavors actually deepen overnight, so it often tastes even better the next day!
For longer storage, freeze your roasted vegetable soup in portion-sized containers or freezer bags for up to 3 months. Leave some space at the top of containers since the soup will expand when frozen. Label with the date so you remember when you made it.
To reheat, thaw frozen soup overnight in the refrigerator. Pour into a saucepan and warm over medium-low heat, stirring occasionally. You might need to add a splash of stock or water if the soup has thickened during storage. I recommend reheating gently to preserve the creamy texture and avoid scorching.
Common Questions About Roasted Vegetable Soup
Can I use different vegetables in this roasted vegetable soup?
Absolutely! Butternut squash, bell peppers, cauliflower, and zucchini all work wonderfully. Just remember that softer vegetables like zucchini need less roasting time, so add them later.
My soup is too thick. How do I fix it?
Simply add more stock or water, a little at a time, until you reach your desired consistency. Reheat gently after thinning. The soup naturally thickens as it sits, so this is very common.
Can I make roasted vegetable soup without cream?
Yes! For a lighter version, skip the cream entirely or use coconut milk for a dairy-free option. You can also blend in a small boiled potato for creaminess without dairy.
How do I prevent my vegetables from burning?
Cut them into uniform pieces and stir them halfway through roasting. If your oven runs hot, lower the temperature by 25 degrees and check more frequently. Vegetables should be caramelized, not charred.
