Roasted Broccoli Soup isn’t just another twist on a classic—it’s a flavor revelation. Did you know that roasting vegetables can boost their flavor profile by up to 40% compared to boiling or steaming? According to culinary studies and taste panels, roasting vegetables like broccoli caramelizes natural sugars, intensifying their depth and richness. That’s precisely what makes roasted broccoli soup a game-changer for cozy weeknight dinners and impressive dinner parties alike.
If you’ve only ever steamed broccoli into submission or tossed it raw into a salad, you’re missing out. This creamy roasted broccoli soup offers a smoky, savory twist on the classic, made with wholesome ingredients and a technique that maximizes flavor without unnecessary complexity. Let’s dive in.
Ingredients List
Gathering the right ingredients is the first step toward achieving a silky, flavor-rich roasted broccoli soup. Here’s what you’ll need:
-
2 heads of fresh broccoli, chopped into florets
Tip: For deeper flavor, keep the stems – just peel and slice them thinly. -
2 tablespoons olive oil
Enhances the caramelization of broccoli during roasting. -
1 medium yellow onion, chopped
-
3 garlic cloves, smashed
-
1 medium russet potato, peeled and diced
This gives the soup body without needing cream. -
4 cups low-sodium vegetable broth
-
1 cup unsweetened almond milk (or any milk of choice)
-
Salt and black pepper, to taste
-
1/4 teaspoon crushed red pepper flakes (optional, for heat)
-
Juice of half a lemon
Brightens the richness and balances the flavors.
Substitution Ideas:
-
Replace russet potato with cauliflower for a low-carb version.
-
Use bone broth instead of veggie broth for added protein.
-
Swap almond milk for oat milk for extra creaminess.

Step-by-Step Instructions
Step 1: Roast the Broccoli
Preheat your oven to 425°F (220°C). Spread the broccoli florets on a baking sheet, drizzle with olive oil, and toss to coat. Roast for 20 minutes, turning once halfway through, until edges are charred and crispy.
Pro Tip: Don’t overcrowd the pan. Crowding leads to steaming instead of roasting, and you want those crispy, golden edges.
Step 2: Sauté Aromatics
In a large pot over medium heat, add a splash of olive oil. Sauté the onions for 4–5 minutes until translucent. Add garlic and stir for another 30 seconds.
Step 3: Add Potato and Broth
Toss in the diced potato and pour in the vegetable broth. Bring to a gentle boil, then reduce heat and simmer for 10–12 minutes, or until potatoes are fork-tender.
Step 4: Combine & Simmer
Add the roasted broccoli to the pot. Let everything simmer together for another 5 minutes to meld flavors.
Step 5: Blend Until Smooth
Using an immersion blender, puree the soup directly in the pot until smooth. Alternatively, work in batches with a countertop blender.
Pro Tip: Want a chunkier texture? Reserve a handful of roasted broccoli to stir in after blending.
Step 6: Add Creaminess & Season
Stir in the almond milk and season with salt, pepper, and red pepper flakes. Finish with a splash of lemon juice to brighten.
