Sheet Pan Broccoli Zucchini Soup is what happens when your sheet pan and blender team up to make a green soup that actually tastes amazing. We’re talking golden-roasted broccoli, zucchini, leeks, onion, and a whole head of garlic (because subtlety is overrated), blended into something creamy, cozy, and shockingly good for you.
It’s the kind of soup that makes you feel virtuous but tastes like you added a block of cheese, which, let’s be honest, we kind of did. (Hi, Boursin.) A splash of cream, a handful of spinach for color and vibes, and boom: a deeply flavorful, velvety green soup that doesn’t taste like sadness. Just roast, blend, swirl, and serve. Bonus: barely any dishes and no sad stovetop simmering. Since it's soup season, I also made a Delicious Roasted Cherry Tomato Soup!

💚 Why You’ll Love This Recipe
Sheet pan sorcery – Roast it all on one tray, toss it in a blender, and boom: gourmet soup with zero stovetop babysitting.
Creamy but not crazy – Thanks to heavy cream and a generous spoonful (ok, half the block) of Boursin, it’s silky without being too rich.
Veg-loaded and secretly filling – Between the roasted broccoli, zucchini, spinach, and a sneaky potato, this one eats like a meal, not just a starter.
Choose your own broth adventure – Go high-protein with chicken broth or keep it veggie-friendly. Either way, flavor for days.
Make once, eat all week – It reheats like a dream and stores beautifully in an airtight container.
💡 Pro Tip: Bonus points if you freeze a batch for Future You.

Ingredient Notes & Tips
Leek & Sweet Onion: The aromatic backbone of the soup, adding a mild, slightly sweet flavor.
Whole Head of Garlic: Roasting garlic cloves mellows them into buttery goodness.
Broccoli: The main star—roasting enhances its nutty side.
Zucchini: Adds bulk and creaminess once blended.
Yukon Potato: Helps thicken the soup naturally.
Spinach: Tossed in before blending for a nutrient boost and beautiful green color.
Cumin & Oregano: Warm spice notes that balance the earthiness of the veggies.
Heavy Cream + Boursin Cheese: Together, they transform this into a silky, indulgent soup.
What to Serve With This Soup
This soup is cozy and filling on its own, but I love pairing it with something crunchy on the side. One of my go-tos? Crispy Za’atar Pita Chips made in the air fryer. They’re the perfect dipper for a creamy soup like this, and they take less than 10 minutes.
Quick Recipe: Crispy Za’atar Pita Chips
Ingredients: 2 pita breads, 3 tablespoon olive oil, 2 tablespoon za’atar spice, ½ teaspoon kosher salt.
Instructions: Cut pitas into 1.5 inch wedges, toss with olive oil, za’atar, and salt. Air fry at 375°F for 6–8 minutes, shaking halfway, until golden and crisp.
Tip: If your pitas have pockets, split them for extra-thin chips.
Serve warm with your soup or store in an airtight container for up to 4 days.

Step 5: Stir in cream and Boursin cheese.

Substitutions & Variations
Dairy-Free: Swap heavy cream and Boursin for cashew cream and nutritional yeast.
Spicy Kick: Add red pepper flakes or cayenne before blending.
Herby Twist: Try parsley or dill instead of basil.
Vegan: Use veggie broth, coconut cream, and dairy-free soft cheese.
Extra Protein: Stir in white beans before blending.
FAQ
I did but optional! Yukon potatoes have thin skins that blend smoothly.
Any high powered blender will give you restaurant-smooth results, but an immersion blender works great too.
