Creamy Lemon Broccoli Pasta with Cashew Sauce
Discover a vibrant vegan pasta dish blending tender broccoli, zesty lemon, and silky cashew cream for a quick, nourishing meal ready in under 30 minutes.

Indulge in the perfect balance of creamy textures and bright citrus notes with this vegan pasta dish. Tender broccoli florets mingle with al dente pasta in a velvety cashew-based sauce infused with fresh lemon, creating a meal that’s both comforting and refreshing. Ideal for busy evenings, this recipe comes together in about 30 minutes using pantry staples and wholesome ingredients.
Why This Pasta Recipe Stands Out
Cashews transform into a luxurious cream when blended, offering a dairy-free alternative that’s rich in healthy fats and protein. Paired with broccoli’s crisp-tender bite and lemon’s tangy lift, the result is a dish that feels indulgent without heaviness. It’s naturally gluten-free adaptable, high in fiber from whole grains, and loaded with vitamins from fresh produce.
- Quick prep: Soak cashews while boiling pasta—no extra time needed.
- Customizable: Swap spaghetti for your favorite noodle or add proteins like chickpeas.
- Nutrient-dense: Broccoli provides vitamin C and K; cashews deliver magnesium and zinc.
Essential Ingredients for Success
Gather these simple components to craft the sauce and assembly. Measurements serve 4 generously.
| Ingredient | Quantity | Purpose |
|---|---|---|
| Raw cashews | 1 ½ cups (200g) | Base for creamy sauce |
| Lemon (juice and zest) | 2 medium | Bright acidity and aroma |
| Broccoli florets | 3 cups (300g) | Vegetable star with crunch |
| Dried pasta (whole wheat or gluten-free) | 14 oz (400g) | Heart of the dish |
| Vegetable broth or water | 1 cup (240ml) | Liquid for blending |
| Nutritional yeast | 2 tbsp (optional) | Cheesy umami boost |
| Garlic | 1 clove, minced | Savory depth |
| Sea salt and black pepper | To taste | Seasoning essentials |
| Fresh basil or parsley | ¼ cup, chopped | Herbaceous finish |
Pro tip: Use high-speed blender for smoothest sauce; raw cashews yield the creamiest results over roasted.
Step-by-Step Cooking Guide
Soak the cashews: Place cashews in a heatproof bowl and cover with boiling water. Let sit 20-30 minutes until softened. This step breaks down their structure for blending.
Prepare the sauce: Drain cashews and transfer to a blender. Add lemon juice, zest, minced garlic, nutritional yeast, salt, pepper, and broth. Blend on high until silky, about 1-2 minutes. Add more liquid if needed for pourable consistency.
Cook pasta and broccoli: Bring a large pot of salted water to a boil. Add pasta and cook per package to al dente, about 8-10 minutes. In the last 3-4 minutes, drop in broccoli florets. They’ll steam perfectly alongside.
Combine everything: Drain pasta and broccoli, reserving ½ cup pasta water. Return to the pot over low heat. Pour in cashew sauce and toss gently. Use reserved water to loosen if thick. Stir in fresh herbs.
Serve immediately: Divide into bowls, garnish with extra lemon zest and cracked pepper. Pairs beautifully with a crisp green salad.
Nutrition Breakdown and Health Benefits
This dish clocks in at around 500 calories per serving, with 15g protein, 10g fiber, and healthy unsaturated fats. Broccoli contributes antioxidants like sulforaphane, linked to anti-inflammatory effects. Cashews provide plant-based protein and heart-healthy monounsaturated fats. Opt for whole wheat pasta to maximize fiber intake, aiding digestion and blood sugar control.
- High in vitamin C from lemon and broccoli for immune support.
- Rich in plant sterols from cashews that may lower cholesterol.
- Vegan, dairy-free, and adaptable for low-carb with zucchini noodles.
Variations to Keep It Fresh
Elevate the base recipe with these twists:
- Protein-packed: Stir in white beans, tempeh, or grilled tofu.
- Spicy kick: Add red pepper flakes or chili oil to the sauce.
- One-pot method: Cook pasta, broccoli, and sauce ingredients together, using pasta water for creaminess.
- Seasonal veggies: Swap broccoli for asparagus, peas, or kale.
- Gluten-free: Use chickpea or lentil pasta for extra protein.
Common Mistakes and Pro Tips
Avoid these pitfalls for restaurant-quality results:
| Mistake | Solution |
|---|---|
| Grainy sauce | Soak cashews fully; use powerful blender. |
| Overcooked broccoli | Add only in final minutes of pasta cook time. |
| Bland flavor | Season generously; taste sauce before tossing. |
| Too thick sauce | Thin with pasta water or broth incrementally. |
Make-ahead: Prepare sauce up to 2 days in advance; store in fridge. Reheat gently with pasta.
Pairing Suggestions
Complement with:
- Drinks: Sparkling water with lemon or a light white wine like Sauvignon Blanc.
- Sides: Arugula salad with balsamic or garlic bread.
- Dessert: Fresh berries or sorbet for citrus harmony.
Frequently Asked Questions (FAQs)
Can I make this without a blender?
Yes, but texture will be less smooth. Finely chop soaked cashews and whisk with liquids, or use store-bought cashew cream.
Is nutritional yeast necessary?
No, but it adds a cheesy flavor mimicking Parmesan. Substitute with a sprinkle of vegan cheese.
How do I store leftovers?
Refrigerate in an airtight container up to 3 days. Reheat with a splash of water to revive creaminess. Freezes well for 1 month.
Can I use roasted cashews?
Raw is best for neutral flavor, but roasted works—adjust salt as they’re often salted.
What’s the best pasta shape?
Long noodles like spaghetti or linguine hold sauce well; short shapes like penne trap more cream.
Scaling for Crowds or Solo Meals
Double ingredients for 8 servings; sauce scales perfectly. For one, halve everything and use half a broccoli head. Batch-cook sauce for multiple meals—it’s versatile over veggies or grains.
This recipe embodies simple, joyful plant-based cooking. Experiment confidently, knowing the core flavors shine through variations.
