The kale is your flavor anchor—look for organic bunches with deep green leaves and no yellowing. Whole Foods or local farmers markets carry the freshest varieties, but the regular grocery store works too if you check the stems for crispness. Quinoa quality matters: Trader Joe's or Bob's Red Mill brands are reliable for even cooking. Toast your cumin seeds in a dry pan for 30 seconds—they'll release their aromatic oils instantly. The cashews should be raw and unsalted; Costco bulk bins offer the best value. Fresh ginger is a game-changer here—its bright zing cuts through the earthiness of kale, so don't skip it unless you're using a high-quality powdered substitute.
No cashews? Macadamia nuts or walnuts work in a pinch, though the texture will differ slightly. Short on vegetable broth? Water plus 1 tbsp soy sauce adds umami depth. The nutritional yeast might be new to you—it's the secret to that cheesy, savory note without dairy. Bob's Red Mill or Bragg are the most accessible brands. For the lemon zest, use an organic lemon if possible—the peel's brightness is worth the extra minute of prep. If you're making this ahead, store the cashew base separately to prevent sogginess, blending it fresh before serving for maximum creaminess.
This soup tastes even better the next day as flavors meld. Store the base (without cashew cream) in an airtight container for up to 5 days in the fridge, or 3 months frozen. The cashew cream keeps separately for 1 week refrigerated. For meal prep, portion into containers and freeze—just reheat with a splash of water. Garnish with lemon zest and toasted almonds right before serving to preserve their freshness. The quinoa will soften slightly upon reheating, so it's perfect for lunches. Double the batch and freeze half; you'll thank yourself when you're craving comfort food on a busy evening.

Step-by-step instructions for amy's kale and quinoa soup
This method transforms simple ingredients into a velvety, nutrient-dense soup with balanced earthy flavors.
Prepare the Base Ingredients
Begin by rinsing the 0.75 cup quinoa thoroughly under cold water in a fine-mesh strainer. This removes any bitterness and ensures even cooking. Place the rinsed quinoa in a medium saucepan with 4 cups vegetable broth and bring to a gentle boil over medium-high heat. Once boiling, reduce heat to low and simmer uncovered for 12-15 minutes until the quinoa is tender and the liquid is absorbed. You'll know it's done when the grains are plump and the mixture resembles a thick porridge.
While the quinoa cooks, heat 0.25 cup extra-virgin olive oil in a large pot over medium heat. Add the 1 whole yellow onion and 4 cloves garlic cloves, cooking for 5-6 minutes until the onion becomes translucent and the garlic releases its aromatic oils. This foundational step builds the soup's flavor profile through proper caramelization.
Develop the Flavor Foundation
Add the 0.5 tsp toasted cumin seeds and 1 tbsp fresh ginger to the pot, stirring constantly for 30 seconds until fragrant. The cumin should sizzle slightly and release its warm, earthy aroma. Immediately add the 4 cups chopped kale leaves, stirring to wilt them slightly. Cook for an additional 3-4 minutes until the kale begins to soften but still retains some vibrant green color.
In a separate small bowl, combine the 0.5 cup soaked raw cashews, 2 tbsp nutritional yeast, 1.5 tsp sea salt, and 0.5 tsp ground black pepper. Using an immersion blender or countertop blender, purée this mixture until completely smooth. This creates a creamy, protein-rich base that will blend seamlessly into the soup later.
Combine and Simmer
Carefully transfer the cooked quinoa mixture to the pot with the onion, garlic, and kale. Stir in the cashew purée and 2 tbsp lemon juice, then bring the entire mixture to a gentle simmer over medium-low heat. Allow the soup to cook for 8-10 minutes, stirring occasionally, until all ingredients are fully integrated and the flavors have melded together. The soup should have a thick, velvety consistency with no visible quinoa grains.
Taste and adjust seasoning if needed. If the soup needs more acidity, add another 1 teaspoon lemon juice. For additional depth, you might want to add a pinch more sea salt or ground black pepper. The soup should be well-seasoned but not overwhelmingly salty.
Finish and Serve
Remove the pot from heat and let the soup rest for 5 minutes. This resting period allows the flavors to fully develop and the soup to thicken slightly. Before serving, stir in the 1 tsp lemon zest and 0.25 cup toasted almond slices, reserving a small portion of the almonds for garnish. The lemon zest adds a bright, citrusy finish that cuts through the earthy flavors of the kale and quinoa.
Ladle the soup into bowls and garnish each serving with a sprinkle of toasted almond slices. Serve immediately while warm, as the flavors will continue to meld even after the soup has been removed from the heat. This soup is particularly satisfying when paired with crusty whole-grain bread or a side salad.
Pro Tips For Making Amy'S Kale And Quinoa Soup
- TOAST THE CASHEWS FIRST: I learned this the hard way—raw cashews straight into soup taste like wet cardboard. Dry them in a 350°F oven for 8–10 minutes, stirring once, until they smell nutty. This makes a real difference in texture and flavor, especially if you’re using them for creaminess later.
- SAUTÉ ONIONS LOW AND SLOW: Cranking the heat on onions just burns them before they soften. Keep it at medium-low and let them cook for 8–10 minutes until translucent and just starting to caramelize—this builds flavor without bitterness. (Yes, even if you’re impatient like me.)
- CHOP KALE STEMS THIN: Whole kale stems turn the soup into a textural nightmare. Slice them into 1/4-inch strips—they’ll soften right along with the leaves. I skip this step sometimes, and the soup feels uneven. Don’t.
- ADD QUINOA LATE: Tossing quinoa in at the start turns it mushy. Wait until the soup’s simmering, then stir it in and cook for just 10–12 minutes—no more. This keeps the grains intact and prevents a gluey mess. (Your future self will thank you.)
Make-ahead tips for leftovers
Prep Ahead Strategy
Start by prepping the quinoa base first—rinse and cook the 0.75 cup quinoa in 4 cups vegetable broth for 12-15 minutes, then store it in an airtight container in the fridge for up to 3 days.
The flavors intensify as it sits, so this step saves you time later. I like to make a big batch of the cashew cream separately too—blend the 0.5 cup soaked cashews, 2 tbsp nutritional yeast, and seasonings, then refrigerate in a sealed jar.
This keeps for 1 week and blends fresh in seconds. 💡
Freezer-Friendly Base
For long-term storage, freeze the cooked quinoa and sautéed veggies (onion, garlic, kale) together in a single layer on a tray before transferring to a freezer bag. This prevents clumping and makes reheating easier.
When ready to serve, thaw overnight in the fridge, then reheat with fresh cashew cream and lemon juice. The texture remains creamy and the flavors stay vibrant. ❄️
Garnish On Demand
Toast your 0.25 cup almond slices and zest the lemon right before serving—these elements lose freshness when stored. I keep the lemon zest and almonds in separate small containers in my fridge, adding them just before eating.
This keeps the soup looking vibrant and tasting bright, even after reheating. A sprinkle of nutritional yeast also adds a cheesy note when freshly applied. 🍋
Reheating Perfection
For best results, reheat soup on the stovetop over medium-low heat, stirring occasionally. If it thickens too much, add 1-2 tablespoons water or broth to restore creaminess. Microwave reheating works in a pinch, but it can make the quinoa slightly mushy—always stir well after heating.
The cashew cream should be blended fresh before adding to maintain its silky texture. 🔥
Meal Prep Timeline
Plan to spend 20 minutes prepping ingredients the night before: chop kale, mince garlic, toast almonds, and soak cashews. Cook the quinoa and sauté veggies in one pot during your main meal, then store components separately.
When ready to serve, combine everything and simmer for 8-10 minutes. This approach cuts your active cooking time in half on busy days. ✨
Portion Control Tips
Use 1-quart glass jars for individual portions—they stack neatly in the fridge and reheat evenly. Store the cashew cream separately in a small container to prevent sogginess. When reheating, add a splash of broth to maintain consistency.
For lunchboxes, pack soup in a thermos with a small container of lemon zest and almonds on the side to add freshness at mealtime. 📅
Nutrition facts
Frequently asked questions
Can I make this soup without cashews?
For a creamy texture without cashews, try blending ½ cup cooked white beans (like cannellini or navy) with 2 tablespoons olive oil and 1 tablespoon nutritional yeast. Or use ½ cup silken tofu blended with 1 tablespoon lemon juice for a lighter option. Both work beautifully and keep the soup vegan-friendly.
How do I prevent the kale from turning mushy?
Kale softens quickly—cook it for only 3-4 minutes after adding to the pot. For extra tenderness without mushiness, remove the tough stems completely and chop the leaves into ½-inch pieces. Add kale later in the cooking process (after onions and garlic) to preserve its vibrant texture.
Is this soup gluten-free?
Yes, this recipe is naturally gluten-free! All ingredients are plant-based and gluten-free. Just double-check your vegetable broth label to ensure it doesn't contain wheat or barley. The quinoa and kale are also gluten-free staples. Perfect for gluten-sensitive diets!
Can I make this soup spicier?
Add ½ teaspoon smoked paprika or ¼ teaspoon cayenne pepper when sautéing the onions. For heat with depth, stir in 1 teaspoon gochujang (Korean chili paste)> during the final simmer. Adjust to taste—start small and add more if needed.
Why does my soup taste bland after reheating?
Reheating can dull flavors because the lemon juice loses brightness. Revive it by adding 1 extra tablespoon lemon juice and a pinch of sea salt while reheating. Stir in fresh lemon zest or a dash of hot sauce right before serving to restore freshness. The cashew cream should also be blended fresh before adding.
