Spinach-Mushroom Orzo With Toasted Walnuts

The aroma always pulls me back. It’s not just the savory dance of sautéed mushrooms and garlic, but the warm, nutty whisper of toasted walnuts. My grandmother used to make a simpler version of this dish – spinach and orzo with a sprinkle of parmesan – but one evening, experimenting in the kitchen, I added the earthy mushrooms and crunchy walnuts, elevating the whole thing to something truly special. It became a family favorite, a dish that felt both comforting and sophisticated, perfect for a weeknight meal or a cozy Sunday supper.

Recipe Overview

• Prep Time: 15 minutes
• Cook Time: 20 minutes
• Total Time: 35 minutes
• Servings: 8
• Dietary Type: Vegetarian

Ingredients

• 1⁄2 cup chopped toasted walnuts (can use 3/4 cup)
• 3 tablespoons olive oil
• 1 medium onion, chopped
• 3 large garlic cloves, chopped (do not finely mince the garlic)
• 1 pinch cayenne pepper (optional and adjust to taste)
• 1⁄2 lb fresh sliced mushrooms (can use more)
• 1 (10 ounce) package frozen chopped spinach, thawed and drained (hand-squeeze dry to remove any excess moisture)
• 3 cups chicken broth
• 1 1⁄2 cups uncooked orzo pasta
• 1⁄3 cup freshly grated parmesan cheese (or to taste)
• Salt & freshly ground black pepper (to taste)

Equipment Needed

• Baking sheet
• Saucepan
• Measuring cups and spoons
• Colander or strainer
• Wooden spoon or spatula

Instructions

1. Begin by toasting the walnuts. Preheat your oven to 350 degrees F (175 degrees C). Spread the chopped walnuts onto a baking sheet in a single layer. Bake for about 8-10 minutes, or until lightly browned and fragrant, tossing them a few times during the baking process to ensure even toasting. Watch them carefully, as they can burn quickly. Once toasted, remove from the oven and set aside.

2. While the walnuts are toasting (or after, depending on your multi-tasking skills!), prepare the vegetables. Chop the onion and garlic. Ensure the spinach is thoroughly thawed and drained of all excess moisture. This is crucial to prevent a watery final dish. The best method is to place the thawed spinach in a clean kitchen towel or several layers of paper towels and squeeze firmly to remove as much liquid as possible. Slice the mushrooms.

3. In a large saucepan, heat the olive oil over medium-high heat. Once the oil is shimmering, add the chopped onion and sliced mushrooms. Cook, stirring occasionally, until the onions are tender and golden brown – this may take about 5-6 minutes or a little longer. The key is to allow the onions to caramelize slightly, which will add depth of flavor to the dish.

4. During the last 2 minutes of cooking the onion and mushrooms, add the chopped garlic and a pinch of cayenne pepper (if using). Stir frequently to prevent the garlic from burning. The cayenne adds a subtle warmth that complements the other flavors; feel free to adjust the amount to your preference.

5. Add the drained spinach to the saucepan and cook, stirring constantly, for 2 minutes, allowing it to wilt and combine with the onion, mushrooms, and garlic.

6. Pour in the chicken broth and bring the mixture to a boil, stirring constantly to ensure everything is well combined.

7. Add the uncooked orzo pasta to the boiling broth. Stir, then reduce the heat to low, cover the saucepan, and simmer gently until the orzo is tender, about 20 minutes. Stir occasionally to prevent the orzo from sticking to the bottom of the pan.

8. Once the orzo is cooked through and has absorbed most of the liquid, remove the saucepan from the heat.

9. Stir in the toasted walnuts and grated parmesan cheese. The heat from the orzo will melt the parmesan, creating a creamy, flavorful sauce.

10. Season the Spinach-Mushroom Orzo with salt and freshly ground black pepper to taste. Remember that the parmesan cheese is already salty, so start with a small amount of salt and adjust as needed.

Expert Tips & Tricks

• Toasting the walnuts is essential for enhancing their flavor and adding a delightful crunch to the dish. Don’t skip this step!
• Ensure you drain the spinach thoroughly. Excess moisture will result in a watery, less flavorful dish.
• For a richer flavor, use homemade chicken broth or a high-quality store-bought broth.
• If you want to add a touch of richness, stir in a tablespoon of butter or a drizzle of cream at the end of cooking.
• This dish is also excellent with other types of mushrooms, such as cremini or shiitake.
• To prevent the orzo from sticking, stir it occasionally during the simmering process.
• If the orzo absorbs all the liquid before it is fully cooked, add a little more chicken broth or water.
• Make ahead tip: You can prepare the spinach-mushroom mixture ahead of time and store it in the refrigerator. When ready to serve, simply add the chicken broth and orzo and continue with the recipe.

Serving & Storage Suggestions

Serve the Spinach-Mushroom Orzo hot as a main course or side dish. It’s delicious on its own or paired with grilled chicken, fish, or tofu. Garnish with extra parmesan cheese and a sprinkle of freshly chopped parsley for added visual appeal.

Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. To reheat, gently warm on the stovetop over low heat, adding a splash of chicken broth or water if needed to prevent it from drying out. You can also reheat it in the microwave. I do not recommend freezing this dish as the texture of the orzo may change upon thawing.

Variations & Substitutions

• For a vegan version, substitute the chicken broth with vegetable broth and omit the parmesan cheese, or use a vegan parmesan alternative. Nutritional yeast can also add a cheesy flavor.
• Add other vegetables, such as diced bell peppers, zucchini, or carrots, to the onion and mushrooms for added nutrition and flavor.
• Use different types of nuts, such as pecans or almonds, instead of walnuts.
• Try using whole wheat orzo for a more nutritious option.
• If you don’t have frozen spinach, you can use fresh spinach, but you will need to use about twice the amount.

FAQs (Frequently Asked Questions)

Q: Can I use dried spinach instead of frozen?
A: I don’t recommend dried spinach. Frozen spinach, once thawed and squeezed dry, provides the best texture and flavor. If you must substitute, use fresh spinach, but increase the amount significantly, as it wilts considerably when cooked.

Q: How can I make this dish spicier?
A: Increase the amount of cayenne pepper, add a pinch of red pepper flakes, or use a spicy sausage instead of mushrooms.

Q: Can I use a different type of pasta instead of orzo?
A: Yes, you can use other small pasta shapes, such as ditalini or acini di pepe. Keep in mind that cooking times may vary depending on the type of pasta you use.

Q: What if I don’t have chicken broth?
A: Vegetable broth works well as a substitute. You can also use water, but the dish will be less flavorful.

Q: Can I add protein to this dish?
A: Absolutely! Grilled chicken, shrimp, or chickpeas would be great additions.
