If you're a fan of creamy pasta and mushrooms, then you're going to love this one-pot orzo! Cooking orzo in one pot results in an ultra-creamy dish in under 30 minutes.

What you'll need

• Orzo: This is a type of pasta that is shaped like a large grain of rice. It can be found in the pasta aisle at most grocery stores. Orzo cooks at a 1:2 ratio, so 1 cup of orzo will need 2 cups of liquid. Just like with risotto, the starches in orzo make this dish naturally creamy without adding any cream or cheese.
• Mushrooms: Baby bella are my go-to due to their rich flavor, but white mushrooms also work. If you don't want big pieces of mushrooms in your orzo you can finely chop them up instead of roughly chopping.
• Shallots: Substitute with white or yellow onion as needed.
• Pesto: While homemade pesto (like my avocado pesto, which is super popular!) is delicious, we're using jarred store-bought pesto in this recipe to cut down on time.
• Capers: This ingredient is super salty, so a little goes a long way. I recommend tasting the dish before adding more!

Step by step instructions

1. Heat a medium pot over medium-high heat. Once hot, drizzle in 1 tablespoon olive oil. Add the shallots, mushrooms and ¼ teaspoon salt. Cook until mushrooms are softened, about 8-10 minutes.
2. Add remaining 1 tablespoon of olive oil. Once hot, add the orzo. Toast orzo for 2-3 minutes, stirring frequently to prevent sticking. This gives the orzo a nutty flavor.
3. Drizzle in a small amount of vegetable broth to deglaze the pot and remove any stuck-on bits of orzo. Add remaining vegetable broth.
4. Bring to a boil over high heat. Once boiling, reduce to a simmer over medium-low and cover. Cook until orzo is cooked through, about 10 minutes.
5. Once the orzo is cooked through (it should be al dente like pasta), remove the lid and stir in remaining ingredients: pesto, chickpeas, spinach and capers. Serve topped with freshly ground black pepper and additional capers if desired. Enjoy!

Recipe FAQ and expert tips

• Serving: Serve mushroom orzo with plenty of freshly ground black pepper and red pepper flakes to each serving. You can also add extra capers to taste.
• Veggies: You can add in extra roasted or steam veggies like zucchini, bell peppers or eggplant when you add the pesto.
• Protein: You can mix in Italian-style veggie sausage or baked tofu for extra protein.

Notes

1. Vegetable broth: I use reduced sodium broth for better control over the salt content. This is reflected in the nutrition facts. You can use water but may need to adjust the seasons.
2. Pesto: Jars vary in size but anywhere around 6-7 ounces works. You can also use homemade pesto.
3. Leftovers: Keep refrigerated in a closed container for 3-4 days. Reheat on the stove over medium-low heat with a splash of vegetable broth or heat in the microwave.
