It’s gluten-free adaptable, nut-free options available, and clocks in at under 500 calories per serving.

Ingredients
Gather simple pantry staples and seasonal produce for this foolproof dish. Yields 4 servings.
| Ingredient | Quantity | Notes |
|---|---|---|
| Butternut squash, peeled and cubed | 3 cups (about 1 lb) | Fresh or frozen; roast for caramelization. |
| Spaghetti or linguine | 12 oz | Gluten-free if needed; high-protein pasta works too. |
| Cashews (soaked) | ½ cup | Or sunflower seeds for nut-free. |
| Nutritional yeast | ¼ cup | For cheesy umami; sub vegan parm. |
| Plant milk (unsweetened) | 1 cup | Almond, oat, or soy for creaminess. |
| Garlic cloves | 3 | Roasted for mellow sweetness. |
| Fresh sage leaves | ¼ cup | For frying; dried works in pinch (1 tsp). |
| Olive oil | 3 tbsp | Plus more for frying. |
| Lemon juice | 1 tbsp | Brightens flavors. |
| Salt & black pepper | To taste | Smoked salt elevates “bacon” vibe. |
| Optional toppings | Coconut bacon, tofu crumbles, breadcrumbs. |
Step-by-Step Directions
Preheat and roast: Set oven to 400°F (200°C). Toss squash cubes with 1 tbsp oil, salt, pepper, and minced garlic on a parchment-lined sheet. Roast 25-30 minutes until fork-tender and edges brown, stirring halfway. This caramelizes natural sugars for depth.
Boil pasta: Cook pasta in salted water per package to al dente. Reserve 1 cup pasta water, then drain. This starchy water thickens the sauce later.
Blend sauce: In a blender, combine roasted squash, soaked cashews, nutritional yeast, plant milk, lemon juice, and remaining garlic. Blitz until ultra-smooth, adding reserved pasta water if too thick. Taste and adjust seasoning—aim for cheesy, garlicky perfection.
Fry sage: Heat 2 tbsp oil in a skillet over medium. Fry sage leaves 1-2 minutes until crisp, then remove to paper towels. This adds aromatic crunch.
Toss together: Return pasta to pot over low heat. Pour in sauce gradually, tossing with tongs until coated and warmed through (2-3 minutes). Add pasta water for silkiness—avoid boiling to prevent separation.
Serve hot: Divide into bowls, top with fried sage, optional coconut bacon, and a nutritional yeast sprinkle. Pairs with green salad or garlic bread.
How to Make Coconut Bacon Topping
Elevate with smoky, crispy coconut flakes—a vegan bacon dupe that’s addictive.
- ¼ cup coconut flakes
- 1 tsp smoked paprika
- ½ tbsp soy sauce or tamari
- 1 tsp liquid smoke (optional)
- Pinch salt
Mix ingredients, spread thinly on a baking sheet. Bake at 350°F for 8-10 minutes, stirring once, until crispy. Cool completely for maximum crunch.

Storage & Make-Ahead Tips
Fridge: Store in airtight container up to 4 days. Reheat gently with splash of plant milk.

Substitutions & Variations

- Gluten-free: Chickpea or brown rice pasta.
- Protein boost: Stir in white beans, tempeh bacon, or lentils.
- Spice it up: Add chili flakes, nutmeg, or pumpkin pie spice.

Expert Tips for Perfection
- Roast at high heat for flavor, not steam—use convection if available.
- Soak cashews 4+ hours or boil 10 minutes for blendability.
- High-speed blender yields smoothest sauce; strain if grainy.
- Fresh sage transforms it—grow your own for pennies.
- Reserve pasta water like gold; it’s the emulsion key.
