Shopping List – Ingredients

• Olive oil – 2 tablespoons (or avocado oil)
• Yellow onion – 1 medium, diced
• Garlic – 3–4 cloves, minced
• Celery – 2 ribs, diced (optional but adds depth)
• Potatoes – 2 medium Yukon Gold or Russet, peeled and cubed (about 1 lb)
• Frozen peas – 4 cups (about 500 g)
• Fresh baby spinach – 4 packed cups (about 120 g)
• Low-sodium vegetable broth – 5 cups (plus more to thin)
• Lemon – zest and juice of 1 (for brightness)
• Fresh herbs – 2 tablespoons chopped parsley or dill (optional)
• Ground black pepper – to taste
• Kosher salt – to taste
• Smoked paprika or chili flakes – optional, for heat
• Greek yogurt or coconut yogurt – optional swirl for serving
• Pepitas or toasted seeds – optional crunch on top

Cooking Instructions

1. Sweat the aromatics. Warm olive oil in a large pot over medium heat. Add onion and celery with a pinch of salt.

   Cook 5–7 minutes until translucent and soft, stirring occasionally. Add garlic and cook 30 seconds until fragrant.

2. Build the base. Add the cubed potatoes and stir to coat in the aromatics. Pour in vegetable broth.

   Bring to a simmer, cover slightly, and cook 12–15 minutes until potatoes are tender.

3. Add the peas. Toss in the frozen peas. Simmer 3–4 minutes until hot and bright green. Don’t overcook—keep that color glowing.
4. Spinach last. Stir in spinach and cook 1–2 minutes until just wilted.

   Remove from heat.

5. Blend to creamy perfection. Using an immersion blender, purée until silky. Or blend in batches in a high-speed blender (vent the lid). Thin with extra broth if needed.
6. Season like you mean it. Stir in lemon zest and juice.

   Add salt and pepper to taste. For a kick, add a pinch of smoked paprika or chili flakes.

7. Optional finishing move. Ladle into bowls and finish with a spoon of Greek or coconut yogurt, a drizzle of olive oil, herbs, and pepitas for crunch. Chefs kiss.

Storage Instructions

• Fridge: Cool completely, then store in airtight containers for 4–5 days.

  It will thicken; add a splash of water or broth when reheating.

• Freezer: Freeze up to 3 months in portioned containers. Leave headspace for expansion. Thaw overnight in the fridge or reheat gently from frozen with a bit of broth.
• Reheat: Low and slow on the stovetop over medium-low, stirring frequently.

  Avoid boiling to keep the color vibrant and flavor fresh.

Why This is Good for You

• Fiber for the win. Peas and potatoes provide soluble and insoluble fiber, which supports gut health, steadier energy, and fullness. Translation: fewer random snack attacks.
• Iron and folate. Spinach brings plant-based iron and folate; pairing it with vitamin C from lemon helps absorption. Smart and tasty—what a concept.
• Protein boost. Peas offer plant protein to make this soup more satisfying than your average veggie blend.
• Antioxidants galore. The vivid green isn’t just pretty; it signals phytonutrients that support overall wellness.

  Your cells are basically applauding.

• Heart-healthy fats. A bit of olive oil adds flavor and helps your body use fat-soluble nutrients.

Common Mistakes to Avoid

• Overcooking the greens. Spinach should just wilt. Cook it to death and you’ll dull the flavor and color. Don’t do that to yourself.
• Skipping the acid. Lemon is not optional if you want a bright, balanced flavor.

  Without it, the soup can taste flat.

• Under-salting. Potatoes and peas need a proper pinch of salt to wake up. Taste as you go—professional move.
• Blending too thick. If the soup looks like mashed potatoes, add more broth. You want luxurious, not gluey.
• Boiling after blending. High heat post-blend can dull color and flavor.

  Warm gently.

Mix It Up

• Protein add-ins: Top with crispy chickpeas, shredded rotisserie chicken, or a poached egg.
• Herb variations: Swap parsley for mint, basil, or dill. Mint + peas = classic spring vibes.
• Spice tweaks: Stir in a teaspoon of curry powder or harissa for a deeper, warming profile.
• Creamy upgrades: Blend in 1–2 tablespoons tahini or a splash of coconut milk for extra richness.
• Crunch factor: Finish with toasted almonds, pepitas, or whole-grain croutons. Texture is half the fun, IMO.
• Low-FODMAP note: Skip onion/garlic, use infused oils, and keep portions modest on peas to suit your needs.

FAQ

Can I use fresh peas instead of frozen?

Yes—use the same amount.

Blanch fresh peas 2–3 minutes before adding, then proceed as directed. Fresh peas are sweeter, but frozen are picked at peak and work perfectly.

What’s the best potato for this soup?

Yukon Gold gives a naturally creamy, buttery texture and holds body after blending. Russets work too but can turn gluey if over-blended, so blend just until smooth.

How do I make it vegan?

It’s already vegan if you skip dairy yogurt.

Use coconut yogurt or a drizzle of olive oil to finish. Everything else stays the same.

Can I make this in a slow cooker?

Yes. Add oil, onion, celery, potatoes, and broth to the slow cooker.

Cook on High 3–4 hours or Low 6–7 until potatoes are tender. Stir in peas and spinach for the last 15–20 minutes, then blend and season with lemon.

Is this freezer-friendly?

Absolutely. Cool fully, portion into containers, and freeze up to 3 months.

Reheat gently with extra broth to loosen. Flavor stays bright if you add fresh lemon after reheating.

How can I add more protein without changing the flavor?

Stir in a scoop of unflavored pea protein or collagen (if not vegan) after blending, or top with Greek yogurt. You can also add white beans during the simmer and blend them in.

My soup turned dull green—what happened?

Likely overcooking the spinach or boiling after blending.

Next time, add spinach at the end and warm gently. A squeeze of lemon will revive the color a bit, FYI.
