What Makes Instant Pot Lemon Parmesan Orzo Great?
Fresh and flavorful food doesn’t have to be complicated. This pressure cooker Parmesan orzo is a testament to the incredible flavor of simple foods.
You simply don’t need a lot of ingredients to create a dish that is full of flavor and completely satisfying.
In fact, you probably have most of the ingredients for this lemon Parmesan orzo in your pantry already, but the key to making this recipe great is the fresh lemon zest and juice.
Sure, you can use bottled lemon juice, but it will not have the same intense, bright flavor of fresh lemons.
The second secret to the great flavor of this pressure cooker Parmesan orzo is frozen peas.
Allowing them to just heat through from the heat of the pasta will keep them crisp and flavorful. You definitely do not want to substitute mushy canned peas in this dish!
Finally, adding fresh herbs to the orzo is a great way to brighten the flavor and take it to the next level. You can easily swap out the herbs, depending on what’s in season, to make the recipe fresh and new all year round.
During the Spring and Summer, I love to add fresh parsley and basil. Fresh mint could also be a tasty addition!

Add minced garlic and stir to combine before canceling the saute function.

Deglaze and season. Next, you’ll deglaze the pan by adding the broth and using a spoon to scrape up any stuck-on bits. Add the lemon zest and black pepper.

Add pasta and cook. Next, you’ll add in the pasta and cook at high pressure for 4 minutes followed by a quick release of pressure.
Add the butter and Parmesan cheese and stir to combine.

Add lemon juice and peas. Next you’ll add in the lemon juice and the frozen peas. Cover for a few minutes and allow the heat of the pasta to warm the peas through.

Add fresh herbs and serve. Last, you’ll stir in any fresh herbs you wish and sprinkle with more Parmesan cheese before serving.

Notes and Adaptations:
- You can serve this as a standalone vegetarian meal, or add some crumbled Italian sausage, grilled chicken or shrimp, or baked fish.

Recommended Equipment:

You mentioned in the email you could use asparagus – how long would you cook that versus the frozen peas?
Hi Melissa! If the asparagus is pretty thin, I would just cut it into segments and stir it in after the pasta cooks, and let it sit in with the pasta (with the lid on) for about 5-7 minutes to soften. If the asparagus is thicker, you could probably just cook it along with the pasta (place it on top of the pasta before cooking). Alternatively, you could cook the asparagus separately in a skillet or in the oven if you want more control over how tender or crisp it is! Enjoy! 🙂
