Full Ingredients

Main Ingredients

• Olive oil: 1 tablespoon
• Italian sausage: 12 ounces (340 g), sliced into 1/2-inch coins (mild or hot)
• Yellow onion: 1 small, finely chopped (about 3/4 cup)
• Garlic: 3 cloves, minced
• Orzo: 1 cup (190 g), dry
• Low-sodium chicken broth: 2 3/4 cups (660 ml)
• Kosher salt: 1/2 teaspoon, plus more to taste
• Black pepper: 1/4 teaspoon, plus more to taste
• Red pepper flakes (optional): 1/4 teaspoon

To Finish

• Baby spinach: 4 packed cups (about 5 ounces / 120 g)
• Parmesan cheese: 1/2 cup (50 g) finely grated, plus more for serving
• Lemon zest (optional): 1 teaspoon
• Lemon juice (optional): 1 tablespoon

Step-by-Step Instructions

Step 1: Heat the pot and prep the sausage

Set a large deep skillet (12-inch) or Dutch oven over medium-high heat. Add 1 tablespoon olive oil and let it heat for about 30 seconds. If your sausage is very fatty, you can start with less oil, but the tablespoon helps prevent sticking and encourages good browning.

Step 2: Brown the sausage

Add the 12 ounces sliced Italian sausage in an even layer. Cook, stirring occasionally, until the edges are well browned and the sausage is mostly cooked through, about 4–6 minutes. Browning builds flavor, so let some pieces sit against the pan for a minute or two before stirring.

Step 3: Soften the onion

Add the chopped onion to the pot. Cook, stirring, until the onion begins to soften and turns slightly translucent, about 2 minutes. If the bottom of the pan is getting too dark, lower the heat slightly to medium.

Step 4: Bloom the garlic, toast the orzo

Add the minced garlic and cook until fragrant, about 30 seconds. Stir constantly so it doesn’t scorch.

Add the dry orzo and stir for 1 minute. This quick toast helps the orzo keep a nice texture and picks up the flavorful fat and browned bits in the pot.

Step 5: Simmer in broth until saucy and tender

Pour in the 2 3/4 cups chicken broth. Stir well, scraping up any browned bits from the bottom (that’s flavor). Stir in 1/2 teaspoon kosher salt, 1/4 teaspoon black pepper, and 1/4 teaspoon red pepper flakes (if using).

Bring to a boil over high heat, then reduce to medium-low to maintain a steady simmer. Cover and cook until the orzo is tender and the mixture looks creamy/saucy, about 10–12 minutes. Stir well after 5 minutes and again near the end to prevent sticking and to help the sauce thicken evenly.

Step 6: Fold in spinach and Parmesan

Turn off the heat. Add the baby spinach in handfuls, folding it in until wilted, about 1–2 minutes.

Stir in the 1/2 cup grated Parmesan until melted and glossy. For a brighter finish, stir in the 1 teaspoon lemon zest and 1 tablespoon lemon juice (optional).

Step 7: Rest, adjust, and serve

Let the orzo rest uncovered for 2 minutes to thicken into a creamy, spoonable consistency. Taste and adjust with additional salt, pepper, and Parmesan as needed.

Serve hot in bowls, topped with extra Parmesan and a pinch of black pepper. If you used lemon, a final whisper of zest on top is a nice touch.

Pro Tips

• Stir at least twice while simmering: Orzo likes to settle; a couple good stirs prevents sticking and keeps the sauce silky.
• Control the consistency: If it gets too thick, stir in an extra 2–4 tablespoons warm broth or water. If it’s too loose, simmer uncovered for 1–2 minutes, stirring.
• Use finely grated Parmesan: It melts smoother than shredded and gives you a more cohesive sauce.
• Don’t overcook the spinach: Add it off the heat so it stays vibrant green and tender.
• Brighten strategically: Lemon zest adds aroma without making it sour; lemon juice adds tang. Use one or both depending on your preference.

Variations

• Creamier version: Stir in 1/4 cup (60 ml) heavy cream or 2 ounces (60 g) cream cheese with the Parmesan.
• Tomato-herb: Add 2 tablespoons tomato paste with the garlic, and finish with 1 tablespoon chopped fresh basil or parsley.
• Veg-forward: Add 1 cup diced zucchini or 1 cup chopped mushrooms with the onion; or swap sausage for 1 (15-ounce) can cannellini beans (drained and rinsed) stirred in at the end.

Storage & Make-Ahead

Cool leftovers to room temperature within 2 hours, then refrigerate in an airtight container for up to 4 days. Orzo will absorb sauce as it sits; reheat gently on the stovetop over medium-low heat or in the microwave, adding 1–3 tablespoons broth or water to loosen. For best texture, avoid freezing (the orzo can become soft and grainy), but it will keep frozen up to 2 months if needed; thaw overnight in the refrigerator before reheating.
