Ingredients You’ll Need

The beauty of Garlic Butter Orzo with Mushrooms and Spinach is just how simple yet impactful the ingredient list is. Each component is chosen for the flavor, color, or rich, cozy texture it contributes, making every bite irresistible.

Orzo: This rice-shaped pasta cooks up tender and creamy, providing the perfect canvas for a luxurious sauce.
Butter: Use it in stages for deep flavor—first to brown the mushrooms and again to create a deliciously silky base.
Mixed mushrooms: A blend of baby bella and shiitake gives earthy depth and a meaty bite to the dish.
Shallot: Milder than onion, shallots add a sweet, aromatic layer to the flavor profile.
Garlic: The star of the show—use plenty to infuse every forkful with savory richness!
Crushed red pepper flakes: Just a pinch for a subtle, warming kick that won’t overpower.
Heavy cream: A splash takes the sauce over the top, making it velvety smooth.
Fine sea salt and freshly-ground black pepper: Season as you go to build balanced flavor throughout.
Parmesan cheese: Freshly-grated adds salty, nutty depth, and helps thicken the sauce beautifully.
Fresh baby spinach: Two big handfuls wilt down into bright, nutritious green ribbons.
Chopped fresh basil: Tossed in at the end, basil lifts everything with a refreshing, herbal note.
Lemon zest and juice (optional): This brings a pop of brightness that ties the dish together.

How to Make Garlic Butter Orzo with Mushrooms and Spinach

Step 1: Heat the water for the orzo

Start by bringing a large pot of generously-salted water to a boil. You want the water ready and waiting so you can drop in the orzo without delay, letting it cook to tender perfection while your mushrooms brown on the side.

Step 2: Brown the mushrooms

In a large sauté pan, melt 1 tablespoon of butter over medium-high heat. Add half of your sliced mushrooms—don’t overcrowd the pan, this lets them caramelize instead of steam. Let them cook undisturbed for a few minutes, then flip and stir until golden brown. Transfer the batch to a plate, repeat with another tablespoon of butter and the rest of your mushrooms, then set aside.

Step 3: Cook the orzo

Add the orzo to your rolling boil. Cook the pasta until it’s just shy of al dente (about 2 minutes less than the package directs), so it will finish cooking perfectly in the sauce later. Reserve some of the pasta water before draining—it’s liquid gold for thickening the sauce!

Step 4: Sauté the veggies

With the mushrooms out of the pan, add your last tablespoon of butter along with minced shallot, garlic, and crushed red pepper flakes. Sauté for about two minutes until fragrant, then stir in the browned mushrooms, heavy cream, a generous pinch of salt, and some pepper. If the orzo needs more time, you can take the pan off the heat at this stage.

Step 5: Combine

When the orzo is ready, add it directly to the mushroom pan along with a cup of reserved pasta water. Stir frequently over gentle heat until the orzo is fully al dente and the sauce begins to cling to each grain, creating that luscious, creamy texture Garlic Butter Orzo with Mushrooms and Spinach is known for.

Step 6: Finish

Remove the pan from the heat. Add a handful of grated Parmesan, all that fresh spinach, chopped basil, and your lemon zest and juice if you’re using it. Gently fold until the spinach just wilts; now’s the moment to check the seasoning and add more salt, pepper, or lemon juice as needed. If you want it creamier, splash in extra pasta water. It’s ready to serve!

Make Ahead and Storage

Storing Leftovers

Any leftover Garlic Butter Orzo with Mushrooms and Spinach keeps beautifully! Transfer it to an airtight container and refrigerate; it will stay fresh and tasty for up to 3 days. The flavors even deepen after a night in the fridge.

Freezing

While best enjoyed fresh, you can freeze this dish in a pinch. Portion into freezer-safe containers, leaving a little extra space for expansion. Let it thaw in the fridge overnight before reheating. Just note that the texture of the spinach and cream may change a touch, but quick reheating helps revive it.

Reheating

Reheat Garlic Butter Orzo with Mushrooms and Spinach gently on the stovetop or in the microwave. Add a splash of water or milk to loosen the sauce as it warms, stirring often to keep it creamy. Top with fresh herbs and cheese for the best flavor.

FAQs

Can I use a different pasta shape?

Absolutely! While orzo provides the classic look and creamy texture this dish is known for, small shapes like ditalini or mini shells also work—just adjust the cooking time accordingly.

What’s the best way to clean mushrooms?

Wipe mushrooms clean with a damp cloth or soft brush to remove dirt. Avoid soaking them, as they’ll absorb water and won’t brown as well during cooking.

Is there a dairy-free version of this recipe?

You can create a dairy-free Garlic Butter Orzo with Mushrooms and Spinach by swapping in your favorite plant-based butter and cream, and using a vegan Parmesan-style cheese or a sprinkle of nutritional yeast for that savory finish.

Can I add protein to make this a full meal?

Definitely. Stir in shredded rotisserie chicken, sautéed shrimp, or crispy tofu cubes alongside the spinach for added protein and heartiness. Each complement the flavors of the dish beautifully.

How can I make this dish even lighter?

To lighten things up, use half-and-half instead of heavy cream, or omit it entirely and rely on the starchy pasta water for creaminess. You can also increase the spinach or add extra herbs for more freshness.
