Ready in one dish and in under an hour, my vegetarian dump-and-bake lemon pepper orzo is creamy and bright! We save time by cooking the orzo and asparagus right in that lemony sauce. It’s a cozy dinner (but not heavy) that’s ideal for busy weeknights or low-effort entertaining!

If you loved my Marry Me Orzo Casserole or Lemon Pepper Chickpeas…this recipe takes everything great about them and throws them together!

This is the kind of recipe I reach for when I want real comfort without standing at the stove. Like my dump & bake veggie pot pie, I love that everything goes into the pan at once and bakes up evenly, with the orzo soaking in lemon pepper flavor as it cooks.

your new go-to veggie-filled dinner

  • No mushy orzo here! Just perfectly cooked pasta ☺️
  • True dump-and-bake ease with no boiling required
  • Minimal prep and minimal dishes – perfect for a weeknight oven pasta recipe

tested again and again…

We tested this specifically to avoid common baked-orzo issues like dry edges or gummy centers. We landed on a method that stays creamy, reheats well, and tastes just as good the next day, which is exactly what I want from an easy vegetarian dinner!

  • Covered Bake: We tested this creamy baked orzo with vegetables both covered and uncovered, and covering the dish was essential to trap steam so the orzo could hydrate evenly without drying out on top.
  • Orzo Quality Check: Different brands absorb liquid differently, so we tested timing ranges and confirmed that higher-quality orzo needs a longer first bake to stay al dente and creamy in a no-boil orzo pasta bake.
  • Chickpeas Optional: We tested this with and without chickpeas – both are great! The chickpeas make the recipe feel more like a main dish, adding a bit of protein and fiber.

Key ingredients

Jump down to the recipe card for exact measurements.

  • Orzo: We tested no-boil methods extensively, and orzo works best because its small shape absorbs liquid evenly in the oven.
  • Asparagus: Adds freshness and texture without releasing too much water during baking. Don’t chop the asparagus too small that it overcooks. Overcooked asparagus will end up mushy and stringy.
  • Lemon Pepper Seasoning: Provides acidity and brightness without needing extra steps or fresh lemon prep. You can make homemade lemon pepper seasoning or use store-bought.
  • Heavy Cream: The higher fat content withstands baking temperatures without curdling. Regular milk or oat milk won’t work, but vegan heavy cream and coconut milk do.
  • Parmesan Cheese: Adds savory depth and helps the sauce thicken naturally as it cools.
  • Spinach: Stirred in at the end so it wilts gently without overcooking.
  • Chickpeas (optional): To add a little protein and fiber, toss in a drained can of chickpeas at the same time as the orzo.

If your orzo gets mushy

This usually means the orzo is overcooked, which is probably because of the quality of the orzo. High-quality orzo needs an additional 10 minutes because the pasta is less processed. If it’s mushy, the orzo is likely lower quality and has been overcooked. It’ll still taste good, but next time just reduce the cooking time!

Need some more protein? Top it with lemon pepper tofu!

What vegetables go well?

A lot of veggies work well in orzo with lemon pepper seasoning! Here are some others we’ve tried and loved from time to time:

  • Mushrooms
  • Basil (instead of spinach or mixed with)
  • Cherry tomatoes
  • Broccoli
  • Zucchini

Notes

*Orzo cooking times differ by the quality of the orzo. For a high-quality Italian orzo, cook closer to 40 minutes during the first bake. Cheaper orzo cooks faster, about 30 minutes.
Storage: This recipe will last in the fridge for up to 4 days in an airtight container. You can also freeze it in a silicone soup mold for up to 3 months. Add a bit more broth to rehydrate it while reheating.
Make-ahead vegetarian pasta: You can prep this casserole the night before and just wait to add the cream until you’re ready to bake. Cover with foil and keep in the fridge until ready to bake.
If the orzo seems dry when you take the foil off the first time, feel free to add more broth on top and give it a good stir.
Can this recipe be made with gluten-free orzo or pasta? No, gluten-free pasta and orzo absorb liquid differently, so the ratios for this recipe will likely not work for gluten-free variations.
Don’t skip the foil: For no-boil pasta bakes cooked in the oven, like in this one-pan orzo bake, it’s important to cover the dish with foil. This keeps all the liquid inside the dish to help the pasta cook. Without the foil, the moisture will evaporate and the top of the pasta will become dry, hard, and won’t cook.

    This was really good. My husband (who is not plant based) also liked it. I couldn’t really taste the lemon pepper, so next time I would probably add more. I used half and half instead of full cream. After the first bake period, it had *just barely* started to curdle, but I stirred the casserole and the finished product showed no signs of curdled cream. I also used kale instead of spinach because that’s what I had on hand. I added the chickpeas, as suggested, but they were a little dry and the dish doesn’t really need them; it was filling enough on its own.

      I enjoyed this recipe! Really yummy flavors and easy to throw together. I made a few changes that turned out really well! 1) I added a can of artichoke hearts (chopped) for some more veggies 2) I used the zest of one lemon and a splash of lemon juice instead of the lemon pepper 3) I used feta cheese instead of Parmesan to make it more Mediterranean. Thanks for the recipe!

    I’ve made it twice now, was so easy for someone who is exhausted after work. I was able to easily make it vegan with soy milk, little vegan butter, and my favorite vegan cheese. One new favs!

    Delicious and easy! Our first casserole and it turned out really nice. We added .5 lb of ground beef which was nice. Our casserole journey has begun 😛

    Delicious! I couldn’t find the lemon pepper in our pantry so subbed juice from half a lemon and increased the amount of pepper. I was also tempted to do a lighter option for the cream but it was delicious as written. My 8 year old had two helpings which is amazing for something non veg. Love how easy and quick this was and will make it again!

      Yes! I haven’t tested this one with rice, though, so you’ll need to adjust the cook time a bit.
