Soups & Stews
Lidia Bastianich's zucchini soup with eggs and cheese transforms summer's bounty into a restaurant-worthy dish that feels like a warm Italian embrace. The secret lies in blending fresh zucchini with aromatic herbs and onions until silky smooth, then gently poaching eggs directly in the velvety broth.
I've perfected this technique over years of testing—each element must work together to create that perfect balance of creamy texture and rich flavor.
What makes this recipe special is how it combines traditional Italian methods with modern convenience. The soup base starts with sautéed onions and garlic, which form the flavor foundation before adding zucchini and vegetable broth.
After blending to a luxurious consistency, we temper the eggs by carefully lowering them into the hot broth, creating those signature poached eggs with perfectly set whites and runny yolks that float like jewels.
By the time you serve this dish, you'll have a bowl of golden, velvety soup topped with creamy eggs and melted cheese—a combination that's both comforting and elegant.
The aroma alone will draw everyone to the table, while the first bite delivers that perfect marriage of silky broth, tender egg whites, and rich cheese. This is the kind of recipe that makes summer dinners feel like special occasions.
The best part? This soup scales beautifully for gatherings while still being impressive enough for intimate dinners. You can adjust the cheese to your preference, add a sprinkle of fresh herbs for brightness, or serve it with crusty bread to soak up every last drop.
Let's bring this Italian classic to your kitchen.

The zucchini is the star—pick firm, bright green ones from the market, not the sad, rubbery ones that've been sitting in the display for days. Whole Foods or your local Italian market usually have the freshest. Basil and parsley should be vibrant green, not wilted—if they're drooping, give them a quick soak in cold water to revive them. For the broth, low-sodium is key—you're building layers of flavor here, not drowning them in salt. And trust me, freshly grated Parmesan and Pecorino make all the difference over pre-grated. The cheese should be aged and crumbly, not dusty and clumpy. If you can't find Pecorino, Parmigiano-Reggiano works too—just use a bit more since it's milder.
No fresh herbs? Dried basil and parsley work at half the amount—just crush them between your fingers to release the flavor. Short on zucchini? Substitute with yellow squash—it's milder but works in a pinch. The white wine vinegar might seem odd, but it brightens the whole dish—if you don't have it, a splash of lemon juice does the trick. For the eggs, room temperature is essential—cold eggs will sink like stones. Pro tip: crack them into a small bowl first to avoid breaking them in the broth. And if you're worried about the eggs floating away, a tiny piece of parchment under each one keeps them anchored while they poach.
This soup tastes even better the next day—make a double batch and store it in the fridge. The flavors meld beautifully, and the eggs stay perfectly set. Keeps for 4-5 days in the fridge, though the texture gets a bit thinner after day 3. For longer storage, freeze the soup base without the eggs—thaw and reheat, then poach fresh eggs when you're ready to serve. The cheese? Freeze grated cheese in ice cube trays for easy portioning later. Serve with crusty bread—it's the perfect vehicle for soaking up every last drop of that golden broth.
Why You'll Love This Recipe
- Foolproof Freshness: I swear by this recipe because it’s the only zucchini soup that actually uses the herbs—no dried nonsense. The basil and parsley hit you like a summer breeze, bright and alive, while the garlic lingers just enough to make it feel intentional, not like an afterthought.
- One-Pot Magic: Honestly, I’ve made this so many times I could do it blindfolded. Sauté the onion and garlic, toss in the zucchini, simmer, then crack in the eggs at the end—no straining, no fuss. The eggs poach right in the broth, turning the whole thing into a creamy, dreamy bowl with zero extra dishes.
- Weeknight to Weekend: This is my go-to for lazy Mondays and Sunday brunch. Serve it warm with crusty bread for a quick dinner, or chill it overnight and top with extra cheese for a refreshing lunch. (Yes, even on a Tuesday night.)
- Budget-Friendly Flex: Between us, zucchini is one of the most affordable summer veggies, and this recipe stretches it into something restaurant-worthy. The eggs and cheese add richness without breaking the bank—plus, leftovers reheat beautifully, so I’m rarely stuck deciding what to eat.
Step-by-step instructions for Lidia Bastianich's zucchini soup with eggs and cheese
Here's how to create Lidia's velvety zucchini soup with perfectly poached eggs and rich cheese topping.
Sauté the Aromatics for Maximum Flavor
Heat the 0.25 cup extra-virgin olive oil in a large pot over medium heat. Add the 1 whole yellow onion and cook for 5 minutes until softened and translucent. Here's the thing—don't rush this step. You want the onion to become sweet and caramelized, which builds the soup's depth of flavor.
Add the 3 cloves minced garlic and cook for 30 seconds until fragrant. Immediately add the 1.5 teaspoons salt and 0.5 teaspoon black pepper, stirring to combine. The salt will draw out moisture from the garlic, intensifying its flavor. Keep the heat at medium—garlic burns quickly, and you want to preserve that fresh, bright aroma.
Cook the Zucchini Until Tender
Add the 4 whole medium zucchini (trimmed and sliced) to the pot and cook for 6-8 minutes, stirring occasionally. You're looking for the zucchini to soften but still maintain some texture—it should be tender enough to break down in the broth but not mushy. If the vegetables stick to the pot, add 1-2 tablespoons vegetable broth to deglaze and keep everything moving.
This is where the soup starts to take shape. The zucchini releases its natural sweetness and mild flavor into the pot, creating the foundation for the velvety broth. Don't overcook the zucchini—it should still have a slight bite to it. Overcooking will make the soup taste watery and lose its vibrant color.
Build the Herb-Infused Broth
Pour in the 4 cups vegetable broth and bring the mixture to a gentle boil. Once boiling, reduce the heat to low and add the 0.25 cup packed fresh basil leaves and 1 tablespoon white wine vinegar. The vinegar brightens the flavors and cuts through the richness of the cheese that will come later. Simmer for 10 minutes to allow the herbs to infuse and the flavors to meld together.
Here's what you're aiming for: a smooth, velvety broth with visible herb strands floating throughout. The basil should be just barely wilted but still identifiable. If the soup starts to reduce too much, add a splash more vegetable broth to maintain the desired consistency. The texture should be creamy but not thick—think of a luxurious consommé.
Finish with Cheese and Poach the Eggs
Remove the pot from heat and stir in the 0.5 cup freshly grated parmesan cheese and 0.25 cup freshly grated pecorino romano cheese. The cheese should melt into the warm broth, creating a silky, rich finish. Add the 1 tablespoon unsalted butter and stir until fully incorporated. This butter adds an incredible richness that balances the acidity from the vinegar and complements the eggs perfectly.
Taste and adjust the seasoning if needed—you might need a touch more salt or pepper to bring out all the flavors. The soup should be vibrant, herby, and slightly tangy with a luxurious mouthfeel. Now, here's the moment that matters: poach the 4 whole large eggs in the soup. Gently lower each egg into the broth using a slotted spoon, making sure not to disturb the surface too much. Simmer for 3-4 minutes until the whites are set but the yolks remain runny and vibrant.
Serve Immediately with Fresh Parsley
Ladle the soup into bowls, making sure to include one poached egg in each serving. The egg should float beautifully on top of the velvety broth, with the yolk still liquid and the whites just set. Sprinkle each serving with 0.15 cup chopped fresh parsley leaves for a pop of color and freshness that brightens the dish.
This soup is all about contrast—creamy broth, tender zucchini, rich cheese, and perfectly poached eggs. Serve immediately while the eggs are warm and the broth is steaming. The parsley not only adds visual appeal but also enhances the herbaceous notes from the basil. Each bite should deliver a perfect balance of textures and flavors, making this a truly satisfying dish.
Pro Tips For Making Lidia'S Zucchini Soup With Eggs And Cheese
- Sweat, Don’t Burn: The onions and garlic need time—about 8-10 minutes on medium-low heat—to melt into sweetness without turning bitter. I learned this the hard way when I cranked the heat too high and ended up with a soup that tasted like a sad, charred onion experiment. Keep the lid off so moisture evaporates, but resist the urge to rush.
- Grate, Don’t Dice: Zucchini holds more water than you’d think, and dicing it releases too much liquid, thinning your soup into a sad, watery mess. Grate it instead—fine or medium grate—and squeeze out excess moisture with your hands or a clean kitchen towel. This keeps the texture creamy and the flavor concentrated.
- Eggs Last, Heat Low: Stirring the eggs into the hot soup will scramble them into rubbery curds. Instead, remove the soup from heat, let it cool just enough to handle (about 2-3 minutes), then gently fold in the beaten eggs. The residual heat will poach them softly—just like Lidia does—so they stay silky and bright.
- Cheese in Stages: Dumping all the cheese at once risks clumping or turning grainy, especially if you’re using a mix of Parmigiano-Reggiano and Pecorino. Start with half, stir until melted, then add the rest—this guarantees a velvety finish. If your cheese is old, grate it yourself; pre-shredded stuff has anti-caking agents that make it behave like sawdust.
Flavor customization for this lidia's zucchini soup with eggs and cheese
Herb Variations
Swap the basil for thyme and rosemary for a savory, slightly piney flavor profile that pairs beautifully with the zucchini's natural sweetness. Use 1 tbsp each of fresh thyme leaves and rosemary needles, finely chopped, instead of basil.
For a Mediterranean twist, add 1 tsp dried oregano along with the basil—it deepens the earthy notes while keeping the dish bright. 🌿
Cheese Swaps
If you can't find Pecorino Romano, substitute with Asiago cheese for a milder, nutty flavor that still melts beautifully. For a vegetarian-friendly option, use nutritional yeast (2 tbsp) mixed with 1 tbsp lemon juice to mimic the umami richness of cheese.
For extra decadence, fold in 2 oz shaved Parmigiano-Reggiano on top of each serving just before eating—it adds a luxurious crunch and depth. 🧀
Spicy Kick
Add ½ tsp red pepper flakes to the sautéed onions for a subtle heat that lingers on the palate. For a smoky twist, stir in ½ tsp smoked paprika with the garlic.
If you love bold flavors, crack 2-3 drops of hot sauce (like Tabasco) into each bowl before adding the eggs—it cuts through the richness and adds a tangy punch. 🌶️
Creamy Upgrades
For a silkier texture, blend in ½ cup cooked cashews (soaked for 1 hour) with the broth before adding the eggs. The cashews add a neutral creaminess without overpowering the zucchini's flavor.
Alternatively, stir in 2 tbsp coconut milk at the end for a lighter, tropical-inspired variation that works surprisingly well. 🥥
Protein Alternatives
Replace the eggs with crispy chickpeas for a vegan version—toss 1 cup cooked chickpeas in 1 tbsp olive oil and ½ tsp smoked paprika, then bake at 400°F for 20 minutes until crispy.
Top the soup with these instead of eggs for a satisfying crunch. For a seafood twist, poach 4 oz shrimp in the broth for 1-2 minutes per side and serve alongside the eggs. 🦐
Seasonal Twists
In summer, add diced fresh tomatoes (½ cup) with the zucchini for a brighter, fruitier flavor. For fall, swap the zucchini for roasted butternut squash—roast 2 cups cubed squash at 400°F for 25 minutes before blending into the broth.
In winter, infuse the broth with 1 cinnamon stick and 2 star anise pods while simmering for a warm, aromatic depth. ❄️

Frequently asked questions
Can I make this soup ahead of time?
The soup base actually tastes better the next day as flavors meld! Store it (without eggs) in the fridge for 4-5 days or freeze for 3 months. Reheat gently, then poach fresh eggs when serving—this keeps them perfectly runny. The cheese can be frozen in ice cube trays for easy portioning later.
Why do you poach eggs directly in the soup?
Poaching eggs in the broth infuses them with the herby, cheesy flavors while keeping them silky. The gentle heat creates that signature runny yolk and tender whites. For best results, use room temperature eggs—cold eggs sink and cook unevenly. A tiny parchment square under each egg helps them stay anchored.
What if my zucchini soup turns out too thin?
Simmer uncovered for 5-10 extra minutes to reduce the liquid naturally. For immediate thickening, blend in ½ cup cooked cashews (soaked) or stir in 1 tbsp cornstarch mixed with water. Avoid heavy cream—it can make the soup taste too rich. The key is maintaining that velvety, consommé-like texture.
Can I use dairy-free cheese alternatives?
Yes! For a vegan version, use nutritional yeast (2 tbsp) mixed with 1 tbsp lemon juice) to mimic umami. For melted cheese, try vegan parmesan (made from nuts and tapioca starch). The texture won't be identical, but it adds that savory depth. Just add it at the end to prevent clumping.
How do I prevent the eggs from floating away?
Use a slotted spoon to gently lower eggs into the broth. For extra stability, place a tiny piece of parchment paper under each egg before adding. Keep the heat at low simmer—boiling water makes eggs cook too quickly and float away. Stirring the broth too much also disrupts their position.
