Ingredients

For this One-Pot Spinach Orzo with Parmesan, you’ll need:

• 1½ cups (300g) orzo pasta, uncooked
• 3½ cups (830ml) low-sodium chicken or vegetable broth
• 2 tablespoons (30ml) olive oil
• 1 medium yellow onion, finely diced (about 1 cup)
• 3-4 cloves garlic, minced (about 1 tablespoon)
• 6 cups (180g) fresh spinach, roughly chopped
• ¾ cup (75g) freshly grated Parmesan cheese, plus more for serving
• 2 tablespoons (30g) unsalted butter
• 1 teaspoon lemon zest (from 1 small lemon)
• 1 tablespoon fresh lemon juice
• ½ teaspoon red pepper flakes (optional)
• Salt and freshly ground black pepper, to taste

The orzo should be the standard rice-shaped pasta variety, while the Parmesan should be freshly grated for the best melting properties and flavor. Fresh spinach works better than frozen in this recipe, as it maintains a better texture and cleaner flavor in the finished cheesy orzo dish.

Pro Tips

Toast the orzo first: Before adding any liquid, spend 2-3 minutes toasting the dry orzo pasta in olive oil until it’s lightly golden. This extra step develops a nutty flavor that elevates the entire one-pot spinach dish and prevents the pasta from becoming too soft or mushy during cooking.

Manage your heat carefully: The key to perfect One-Pot Spinach Orzo with Parmesan is controlling the heat. Start with medium-high heat to bring the mixture to a simmer, then immediately reduce to low. A gentle simmer ensures the orzo cooks evenly without sticking to the bottom, while still allowing enough time for the starch to release and create that creamy texture without burning.

Add spinach in batches: Rather than dumping all the spinach in at once, add it in 2-3 batches, stirring between additions. This technique allows each portion to wilt properly and integrate into the Parmesan orzo mixture without cooling the entire dish or creating uneven pockets of spinach. The final result will be a perfectly distributed blend of greens throughout your creamy pasta.

Instructions

Step 1: Heat olive oil in a large, deep skillet or Dutch oven over medium heat. Add the diced onion and cook for 3-4 minutes until translucent. Add the minced garlic and cook for another 30 seconds until fragrant, being careful not to let it brown.

Step 2: Add the dry orzo pasta to the pan and toast it for 2-3 minutes, stirring frequently, until it begins to turn lightly golden. This step adds a wonderful nutty flavor to your One-Pot Spinach Orzo with Parmesan.

Step 3: Pour in the broth, add ½ teaspoon salt and ¼ teaspoon black pepper, and bring the mixture to a boil. Once boiling, reduce the heat to low, cover, and simmer for about 10-12 minutes. Stir occasionally to prevent sticking. The orzo should absorb most of the liquid and become tender.

Step 4: When the orzo is almost tender and most of the liquid has been absorbed (it should still look slightly loose as the sauce will thicken as it sits), begin adding the spinach in batches. Stir in one-third of the chopped spinach and allow it to wilt for about 1 minute before adding the next batch, continuing until all spinach is incorporated.

Step 5: Remove the pan from heat and immediately stir in the grated Parmesan cheese, butter, lemon zest, lemon juice, and red pepper flakes if using. Mix thoroughly until the cheese melts and creates a creamy sauce that coats the orzo and spinach.

Step 6: Let the One-Pot Spinach Orzo with Parmesan stand for 2-3 minutes to thicken slightly. Taste and adjust seasonings as needed, adding more salt and pepper if desired. The consistency should be creamy but not soupy – if it’s too thick, you can add a splash more broth.

Step 7: Serve immediately in warm bowls, topped with additional freshly grated Parmesan cheese and a crack of black pepper. This spinach Parmesan pasta is at its creamiest when freshly made, so enjoy it right away!

Variations

Mediterranean Spinach Orzo: Transform this One-Pot Spinach Orzo with Parmesan into a Mediterranean delight by adding ½ cup halved cherry tomatoes, ¼ cup pitted and chopped Kalamata olives, and ½ cup crumbled feta cheese (replacing some of the Parmesan). Finish with fresh chopped basil and a drizzle of extra virgin olive oil for a bright, flavor-packed variation.

Protein-Packed Option: For a heartier meal, add protein to your orzo with spinach. Stir in 2 cups of shredded rotisserie chicken, 1 pound of sautéed shrimp, or 1 can of drained and rinsed white beans during the last few minutes of cooking. This transforms the dish from a side into a complete one-pot meal while maintaining all the creamy Parmesan goodness.

Gluten-Free Adaptation: This comforting dish can be made gluten-free by substituting the orzo with a gluten-free rice-shaped pasta or even arborio rice (though cooking times will need to be adjusted for rice). The creamy texture and Parmesan flavor work beautifully with these alternatives, making the dish accessible for those with gluten sensitivities.

Storage & Serving

This One-Pot Spinach Orzo with Parmesan can be stored in an airtight container in the refrigerator for up to 3 days. When reheating, add a splash of broth or water and warm gently over medium-low heat, stirring frequently to restore its creamy consistency. The dish tends to thicken considerably when chilled, so additional liquid is essential for bringing back its original texture.

For serving, pair this creamy orzo with spinach alongside a simple protein like lemon-herb roasted chicken, pan-seared fish, or grilled shrimp for a complete meal. It also works beautifully alongside a bright arugula salad with lemon vinaigrette to balance the richness of the Parmesan sauce.

For an elegant presentation, serve the orzo in warmed shallow bowls, garnished with additional Parmesan shavings, a sprinkle of fresh herbs like basil or parsley, and a light drizzle of your best olive oil. For a special touch, add a few toasted pine nuts on top for a pleasant textural contrast to the creamy pasta.

FAQs

Can I use frozen spinach instead of fresh?
Yes, you can substitute frozen spinach, but thaw it completely and squeeze out excess moisture before adding. Use about 1½ cups of thawed frozen spinach in place of the 6 cups fresh, and add it slightly earlier in the cooking process.

Why is my orzo sticking to the bottom of the pot?
This typically happens when the heat is too high or you’re not stirring frequently enough. Keep the heat at a gentle simmer and stir every few minutes, especially toward the end of cooking time, to prevent sticking in your One-Pot Spinach Orzo with Parmesan.

Can I make this dairy-free?
Absolutely! Substitute the Parmesan with nutritional yeast or a dairy-free Parmesan alternative, and replace the butter with additional olive oil or vegan butter. The dish won’t have the same depth of flavor but will still be delicious.

How can I make this ahead for a dinner party?
Make it up to an hour ahead, but keep it slightly looser than desired by adding extra broth, as it will continue to absorb liquid as it sits. Reheat gently with a splash more broth, stirring constantly, and add the final Parmesan just before serving.

Can I double this recipe?
Yes, this recipe doubles well, but use a larger pot to ensure even cooking and be prepared to extend the cooking time slightly. The larger volume may take a few extra minutes for the orzo to become tender.

This One-Pot Spinach Orzo with Parmesan is comfort food at its finest — creamy, satisfying, and deceptively simple to prepare.
