From the roundup: 20 Zucchini Pasta Dinner Recipes Ready in 30 Minutes
This zucchini pasta soup with orzo is what I make on the nights when I want something that feels like real cooking but only have about 30 minutes and one pot to work with. The active part is maybe 10 minutes: dice the onion, cut the zucchini, drop in a Parmesan rind from the freezer. After that the soup mostly takes care of itself.
The Parmesan rind is the thing that makes the broth taste like you did something special. I keep a zip bag of rinds in the freezer and grab one whenever I need it. Even a small piece, two or three inches, turns plain chicken broth into something with actual body. Do not skip it if you have one.
One thing to watch: the orzo keeps absorbing liquid after you pull the pot off the heat. If you are feeding four people right away, it is perfect. If dinner gets pushed back 20 minutes because someone forgot soccer cleats, stir in a splash of broth before you ladle it out.
Why you will love this
- One pot, 30 minutes, and the prep is mostly just dicing zucchini and onion.
- The Parmesan rind does real work here, the broth tastes slow-cooked even though it is not.
- It lands between a light pasta dish and a bowl of soup, filling enough for dinner without feeling heavy.
- My kids eat the orzo and mild broth without complaint, which is not something I can say about every vegetable-forward dinner.
- Leftovers reheat well for lunch the next day with just a splash of extra broth stirred in.
Tips for success
- Do not rush the onion. Four minutes over medium heat until it is soft and translucent gives the broth a sweeter base. Pull it early and the broth tastes flat.
- Stir the orzo every couple of minutes while it simmers. It will stick to the bottom of the pot if you walk away, and a scorched spot will flavor the whole batch.
- Pull the pot off the heat as soon as the orzo has a slight chew. It keeps cooking in the hot broth, so slightly underdone at the stove means just right in the bowl.
- Fish out the Parmesan rind before you taste for salt. The rind adds sodium as it cooks, so season at the end, not the beginning.
If the soup gets too thick
- Orzo absorbs a lot of liquid as it sits. If the leftovers look more like pasta than soup, add a quarter to half cup of chicken broth or water when you reheat.
- Reheat on the stove over medium-low, not in the microwave, so the orzo warms through evenly without turning to mush.
- If the broth tastes thin before serving, let it simmer uncovered for an extra two or three minutes. The starch from the orzo will tighten it up.
Substitutions
For a vegetarian version, swap in vegetable broth and use a piece of Parmesan rind or two tablespoons of white miso stirred in at the very end for that same savory depth. Ditalini or small elbow macaroni work fine in place of orzo; just check the package cook time and adjust accordingly. Yellow squash can replace half or all of the zucchini if that is what you have.
For picky eaters who pick around anything green: skip the parsley and cut the zucchini into smaller pieces so it softens more into the broth. My middle one does not notice it at all when the cubes are small enough.
Make-ahead and storage
You can make the broth base with the zucchini up to two days ahead and keep it in the fridge. When you are ready to eat, bring it back to a simmer and cook the orzo fresh. This is worth doing if you want a genuinely quick weeknight dinner with almost no active time that evening.
Leftovers keep in an airtight container in the fridge for up to four days. The orzo will soak up most of the broth overnight, so add a splash of chicken broth or water and reheat on the stove over medium-low. This soup can be frozen for up to two months, but freeze it before adding the Parmesan garnish and expect the orzo to be softer once thawed. It is still good, just more of a thick, stewlike texture than a clear broth soup.
Zucchini Pasta Soup with Orzo and Parmesan Broth
Ingredients
Equipment
Method
- Heat the olive oil in a large saucepan or Dutch oven over medium heat. Add the diced onion and cook, stirring occasionally, for about 4 minutes until it softens and turns translucent. Do not rush this step. Soft onion gives the broth a sweeter base.
- Add the minced garlic and red pepper flakes if using. Stir and cook for about 1 minute until the garlic smells fragrant but has not browned. Garlic burns quickly at this stage, so keep it moving.
- Add the diced zucchini, season with the salt and black pepper, and stir to coat everything in the oil. Let the zucchini cook for 2 minutes, just long enough to start softening slightly on the edges.
- Pour in the chicken broth and drop in the Parmesan rind. Raise the heat to medium-high and bring the broth to a gentle boil. You will see the rind start to soften and release its flavor into the liquid.
- Stir in the dry orzo. Reduce the heat to a steady simmer and cook uncovered for 9 to 10 minutes, stirring every couple of minutes so the orzo does not stick to the bottom. The orzo should be tender but still have a slight chew, and the broth will thicken slightly from the starch.
- Fish out the Parmesan rind with a spoon and discard it. Taste the broth and adjust salt and pepper as needed. Ladle the soup into bowls, top each one with a generous pinch of grated Parmesan, a drizzle of olive oil, and a little chopped parsley if you have it. Serve right away with crusty bread on the side.
