Ingredients You’ll Need

You only need a dozen or so simple pantry staples and a few fresh ingredients to pull off this soup, but don’t underestimate their impact! Each adds its own special flavor, aroma, or color, making your Pesto Broccoli Orzo Soup nourishing and knockout delicious.

• Garlic bulb: Roasting the garlic releases sweetness and adds a mellow, rich undertone to the soup.
• Olive oil: High-quality olive oil keeps the veggies roasting beautifully and adds a fruity depth.
• Broccoli crowns (about 3 small heads): The star of the show, lending a tender bite and bright green color.
• Garlic powder: Deepens the garlicky flavor and enhances the roasted vegetables.
• Fresh thyme: Offers a fragrant, woodsy note that pairs perfectly with broccoli.
• Shallots, diced: Adds subtle sweetness and savoriness, more delicate than onions.
• Fennel seeds: Brings a hint of anise and a fresh, aromatic lift to the base.
• Red pepper flakes (optional): For just a whisper of heat and dimension—skip if you prefer it mild.
• Vegetable broth: A good quality broth forms the flavorful backbone of the soup, so use your favorite.
• Warm water (or more vegetable broth): Helps balance the richness and adjust the soup’s consistency.
• Orzo: This tiny pasta acts like a sponge, adding a pleasant chew and helping to make the soup hearty.
• Lemon zest and juice: Brings zesty brightness and lifts every other flavor in the bowl.
• Pesto (homemade or store-bought, dairy-free): Swirled in at the end, this is where the soup really sings with herbaceousness.
• Fresh dill: For a final garnish with a pop of color and fresh, garden flavor.
• Kosher salt and pepper: Essential for balancing every other flavor—season to taste.
• Plant-based “feta” (for topping): Gives a creamy, tangy contrast that feels special and adds protein.

How to Make Pesto Broccoli Orzo Soup

Step 1: Roast the Garlic

Start by preheating your oven to 425F. Cut about 1/4-inch off the top of a whole garlic bulb so you reveal a peek of each clove; drizzle 1–2 teaspoons of olive oil over the top and sprinkle with a pinch of salt. Wrap the garlic snugly in foil, pop it on the oven rack, and roast for 35–40 minutes until it turns deeply golden and silky soft. Roasted garlic is what sets this soup apart, infusing it with an irresistible layer of savory sweetness.

Step 2: Prepare and Roast the Broccoli

While your garlic is getting cozy in the oven, cut two of the broccoli heads (including the stems) into small, bite-sized pieces. The remaining head gets cut into pretty florets for topping later. Toss all the broccoli onto a large baking tray with 1 tablespoon of olive oil, garlic powder, half the fresh thyme, and a generous sprinkle of kosher salt. Mix it all together, lay the florets cut side down, and roast for 20 minutes. You’ll end up with charred, crispy edges and a rich roasted flavor that gives this soup its comforting warmth.

Step 3: Sauté the Aromatics

Once your garlic is cool enough to handle, heat the remaining tablespoon of olive oil in a large soup pot over medium heat. Add diced shallots and a pinch of salt, letting them sweat for 2–3 minutes until they’re soft and fragrant. Toss in the fennel seeds and optional red pepper flakes. Then, squeeze out the roasted garlic cloves straight from the bulb into the pot—don’t be afraid to get a little messy! Lightly mash the garlic and stir it all together until it’s wonderfully aromatic.

Step 4: Add Broccoli, Broth, and Orzo

Scoop about two-thirds of your roasted broccoli (reserve the rest for toppings) into the pot with the aromatics. Pour in the warm vegetable broth and water. Bring everything to a gentle boil, then stir in the orzo and remaining thyme. Let it simmer for about 9–10 minutes, stirring regularly so the orzo won’t stick. This step allows the orzo to soak up all that roasted flavor, making each spoonful heartier and more delicious.

Step 5: Finish with Lemon, Pesto, and Serve

Once the orzo is just al dente, take the soup off the heat. Stir in the lemon zest, a squeeze of fresh lemon juice, and your dairy-free pesto. Taste and adjust with more salt and pepper as needed. Ladle the soup into bowls, then top each one with a scoop of the reserved charred broccoli, a crumble of plant-based “feta,” and a sprinkle of dill. Each spoonful feels like a bright, herby embrace—enjoy!

How to Serve Pesto Broccoli Orzo Soup

Garnishes

Garnishing your Pesto Broccoli Orzo Soup is half the fun (and all the flavor)! Scatter reserved roasted broccoli on top for texture, add a generous crumble of plant-based “feta,” and finish with a fresh sprinkle of dill or extra pesto. A drizzle of olive oil and a crack of black pepper make it feel restaurant-worthy.

Side Dishes

Pair your soup with a warm, crusty sourdough or a slice of grilled ciabatta to help mop up all the herby broth. For something extra comforting, try a simple leafy green salad with a lemony vinaigrette—the bright acidity complements the soup perfectly without overpowering.

Creative Ways to Present

Take your presentation up a notch by serving your Pesto Broccoli Orzo Soup in wide bowls topped with a swirl of extra pesto for dramatic effect. For gatherings, try ladling the soup into little mugs or shooters and topping each with a mini skewer of charred broccoli and “feta” for a fun soup starter. Even a sprinkle of crispy roasted chickpeas or toasted seeds can add crunch and intrigue!

Make Ahead and Storage

Storing Leftovers

Keep any leftover Pesto Broccoli Orzo Soup in an airtight container in the fridge for up to four days. The flavors actually deepen overnight, making the soup even more delicious on day two. If the orzo soaks up too much liquid, just stir in a little extra broth or water before serving.

Freezing

You can absolutely freeze this soup! Scoop the cooled soup into freezer-safe containers, leaving a little room at the top for expansion. It will keep well for up to three months. Note that orzo pasta may get a bit softer after thawing, but the flavors stay bright and bold.

Reheating

To reheat, simply pour the soup into a pot and warm it gently over medium heat, adding more broth or water as needed to loosen the consistency. If you’re microwaving, cover loosely and heat in bursts, stirring frequently for even warmth. Finish with a squeeze of fresh lemon juice to reawaken all those herby, vibrant notes.

FAQs

Can I use frozen broccoli instead of fresh?

Absolutely! If using frozen broccoli, there’s no need to thaw first. Just roast it straight from the freezer, keeping a close eye on the baking time as it may roast a bit faster than fresh. You’ll still achieve deliciously tender, flavorful results for your Pesto Broccoli Orzo Soup.

How do I make this gluten-free?

To make your Pesto Broccoli Orzo Soup gluten-free, simply swap out the regular orzo for your favorite gluten-free orzo or another small gluten-free pasta shape. Everything else in the recipe is naturally gluten-free, so you’re good to go!

What kind of pesto is best for this soup?

A classic basil pesto (homemade or store-bought) is wonderful, but feel free to get creative! A dairy-free pesto with extra lemon, arugula, or even kale works beautifully, especially for those who want a more peppery or earthy flavor profile.

Can I double the recipe for meal prep?

Definitely! Just use a large stockpot to accommodate the extra volume, and double all your ingredients. It’s perfect for meal prepping, lunch packing, or sharing with friends and family throughout the week. Remember to adjust your salt and seasonings as you go.

Will the soup thicken as it sits?

Yes, orzo continues to absorb liquid even after cooking, so your Pesto Broccoli Orzo Soup may thicken considerably in the fridge. Just add a splash of broth or water each time you reheat, and stir well to restore its soupy magic.

Final Thoughts

If you’re looking for an easy, fresh, and absolutely golden bowl of goodness, there’s no better place to start than this Pesto Broccoli Orzo Soup.
