How to Make It

1. Prep the base. Add onion, carrots, celery, garlic, oregano, thyme, bay leaf, and a drizzle of olive oil to the slow cooker.

   If you like, lightly sauté the veggies in a pan first for extra flavor, but it’s optional.

2. Pour in the broth. Add the chicken or vegetable broth. If using a Parmesan rind, toss it in now.
3. Slow cook. Cover and cook on Low for 5–6 hours or on High for 2–3 hours, until the vegetables are tender.
4. Add the orzo. Stir in the orzo and cook for another 20–30 minutes on High, until the pasta is tender but not mushy. Stir once or twice to prevent sticking.
5. Finish with greens and lemon. Remove the bay leaf (and Parmesan rind).

   Stir in the spinach or kale, letting it wilt for 2–3 minutes. Add lemon zest and juice. Start with the zest and juice of one lemon, then add more to taste.

6. Season and serve. Add salt, pepper, and red pepper flakes if you like.

   Stir in chicken now if using, just to warm through. Ladle into bowls and top with fresh parsley or dill. A sprinkle of grated Parmesan is a nice touch.

How to Store

• Refrigerator: Store leftovers in an airtight container for 3–4 days.

  The orzo will continue to absorb liquid, so you may want to add a splash of broth or water when reheating.

• Freezer: For best results, freeze the soup without the orzo. Cook and cool the base, freeze up to 3 months, then add fresh orzo when reheating. If already combined, it’s still fine to freeze, but expect softer pasta.
• Reheat: Warm gently on the stovetop over medium heat, adding liquid as needed.

  Avoid boiling to keep the orzo from breaking down.

Why This is Good for You

• Light but satisfying: Orzo adds carbs for energy without the heaviness of cream-based soups.
• Vitamin-rich veggies: Carrots, celery, and greens deliver fiber, vitamins A and K, and antioxidants.
• Lemon and garlic boost: Lemon provides vitamin C and brightness; garlic brings beneficial compounds and big flavor.
• Protein options: Add chicken or keep it plant-based with veggie broth—either way, it’s wholesome and nourishing.

Common Mistakes to Avoid

• Adding orzo too early: It will swell and turn mushy if it cooks for hours. Add near the end.
• Skipping the lemon zest: The zest adds deep citrus flavor without extra acidity. Don’t rely only on juice.
• Under-seasoning: Broth salt levels vary.

  Taste and adjust at the end, especially after adding lemon.

• Forgetting to stir the orzo: It can clump. Give it a couple of stirs during those last 20–30 minutes.
• Overcooking greens: Add spinach or kale at the end to keep color and texture fresh.

Variations You Can Try

• Lemony Greek-style: Stir in fresh dill and a handful of crumbled feta before serving.
• Avgolemono-inspired: Whisk two eggs with lemon juice, then temper with hot soup and stir in off heat for a silky finish.
• Vegan version: Use vegetable broth, skip Parmesan, and finish with a splash of olive oil and nutritional yeast.
• Herb swap: Try basil and parsley in summer, or rosemary and thyme in cooler months.
• Protein twist: Use chickpeas instead of chicken, or add cooked turkey or rotisserie chicken for convenience.
• Extra veggies: Add zucchini, mushrooms, or peas in the last 20 minutes for more texture and color.
• Creamy finish: Stir in a splash of half-and-half or coconut milk at the end for a richer broth.

FAQ

Can I cook the orzo separately?

Yes. Cook it on the stovetop until just al dente, then add to the soup when serving.

This helps control texture and prevents the pasta from absorbing too much broth.

What size slow cooker should I use?

A 5- to 6-quart slow cooker is ideal. If yours is smaller, halve the recipe or reduce the broth to avoid overflow.

How much lemon should I add?

Start with the zest and juice of one lemon, then taste. You can add more juice for brightness or more zest for a deeper citrus aroma.

The right amount depends on your broth’s saltiness and your personal preference.

Can I use rice instead of orzo?

You can. Use 3/4 cup of white rice and add about 30–35 minutes before serving. Brown rice takes longer and may need extra liquid.

Do I need to sauté the vegetables first?

No, but sautéing adds extra flavor.

If you’re short on time, add everything straight to the slow cooker—it will still be delicious.

How do I keep the soup from getting too thick when reheating?

Add more broth or water as it warms. The orzo continues to absorb liquid in the fridge, so loosening it up brings back a nice, soupy consistency.

Can I make this on the stovetop?

Yes. Sauté the vegetables in a large pot, add broth, simmer until tender (about 15–20 minutes), then add orzo and cook until al dente.

Finish with lemon and greens.
