Ingredients
The magic of this dish starts with a handful of high‑impact ingredients. Fresh red bell peppers provide the smoky backbone, while cashews deliver a silky, dairy‑free richness. Aromatics like garlic and shallots deepen the flavor, and a splash of smoked paprika adds a whisper of heat. Finally, a generous handful of grated Parmesan ties everything together with salty umami.
Produce
- 3 large red bell peppers
- 2 cloves garlic, minced
- 1 small shallot, finely diced
- 1 handful fresh basil leaves, torn
Pantry & Dairy
- 1 cup raw cashews (soaked)
- ½ cup grated Parmesan cheese
- 2 tablespoons olive oil
- ¼ cup vegetable broth (or pasta water)
Seasonings
- 1 teaspoon smoked paprika
- ½ teaspoon red‑pepper flakes (optional)
- Salt and freshly ground black pepper, to taste
Pasta
- 12 oz (340 g) linguine or fettuccine
These ingredients work in harmony: the roasted peppers provide a sweet, smoky base; cashews give a luxurious cream without dairy; garlic and shallot layer aromatic depth; and the Parmesan adds a salty finish. Together they create a sauce that clings to every strand of pasta, delivering comfort in each bite.
Step-by-Step Instructions
Roasting the Red Peppers
Preheat your oven to 450°F (230°C). Slice the peppers in half, remove seeds, and place them skin‑side up on a baking sheet lined with parchment. Drizzle with 1 tablespoon olive oil and sprinkle lightly with salt. Roast for 20‑25 minutes, turning once, until the skins blister and blacken. When done, transfer to a bowl, cover with plastic wrap for 5 minutes, then peel off the skins. The softened flesh is ready to be blended into a silky puree.
Cooking the Pasta
Bring a large pot of salted water to a rolling boil. Add the linguine and cook according to package directions until al dente, usually 9‑11 minutes. Reserve ½ cup of the starchy pasta water, then drain the noodles. The reserved water will later help emulsify the sauce and keep the pasta moist.
Preparing the Creamy Sauce
- Blend the Base. In a high‑speed blender, combine the peeled roasted peppers, soaked cashews (drained), ¼ cup vegetable broth, smoked paprika, and a pinch of red‑pepper flakes. Blend until completely smooth, about 30 seconds. The mixture should be thick yet pourable; add a splash more broth if needed.
- Sauté Aromatics. While the pasta cooks, heat the remaining 1 tablespoon olive oil in a large skillet over medium heat. Add the diced shallot and sauté for 2‑3 minutes until translucent. Stir in the minced garlic and cook another 30 seconds, being careful not to let it brown.
- Combine and Simmer. Pour the blended pepper‑cashew mixture into the skillet with the aromatics. Reduce heat to low and let the sauce simmer gently for 4‑5 minutes, stirring frequently. This step allows the flavors to meld and the sauce to thicken slightly.
- Finish the Sauce. Stir in the grated Parmesan and the reserved pasta water. Continue to whisk until the cheese melts and the sauce becomes glossy, coating the back of a spoon. Taste and adjust seasoning with salt and pepper.
Tossing Everything Together
Add the cooked linguine directly to the skillet, tossing to coat each strand evenly with the creamy red‑pepper sauce. Cook for an additional 1‑2 minutes, allowing the pasta to absorb some of the sauce. Remove from heat, stir in torn basil leaves, and serve immediately. A final sprinkle of Parmesan and a drizzle of extra‑virgin olive oil adds a luxurious finish.
Tips & Tricks
Perfecting the Recipe
Soak Cashews Overnight. For the smoothest sauce, soak cashews for at least 8 hours or use hot water for a quick 30‑minute soak. This ensures a truly creamy texture without graininess.
Peel Peppers While Warm. Cover the roasted peppers with a kitchen towel for a few minutes; the steam loosens the skins, making them easier to remove without tearing the flesh.
Flavor Enhancements
Add a splash of sherry vinegar or fresh lemon juice right before serving for a bright, acidic lift. For an extra layer of umami, stir in a teaspoon of miso paste or a drizzle of truffle oil during the final toss.
Common Mistakes to Avoid
Avoid over‑blending the sauce with hot pasta water; too much liquid can turn the sauce watery. Also, don’t skip the resting time for the roasted peppers—this step is crucial for easy skin removal and deeper flavor.
Pro Tips
Use a Heavy‑Bottomed Pan. A sturdy skillet distributes heat evenly, preventing scorching of the delicate sauce and ensuring a consistent simmer.
Reserve Pasta Water Early. Scoop the starchy water before draining the noodles; it helps bind the sauce to the pasta and adds a silky mouthfeel.
Finish with Fresh Herbs. Adding basil at the end preserves its bright flavor and color, preventing it from wilting during cooking.
Serve Immediately. The sauce thickens as it cools; plating right away keeps the pasta luxuriously coated and prevents it from drying out.
Variations
Ingredient Swaps
Swap the cashews for soaked almonds or silken tofu for a different texture while keeping the sauce dairy‑free. Replace linguine with gluten‑free penne or whole‑wheat spaghetti for a heartier bite. If you prefer a smoky depth, use fire‑roasted jarred peppers instead of fresh‑roasted ones.
Dietary Adjustments
For a vegan version, omit Parmesan and substitute with nutritional yeast or a vegan Parmesan blend. Those on a low‑carb plan can serve the sauce over spiralized zucchini noodles. To make it keto‑friendly, replace the pasta with shirataki noodles and increase the fat content by adding a tablespoon of coconut cream.
Serving Suggestions
Pair the pasta with a crisp arugula salad tossed in lemon vinaigrette for contrast. A side of garlic‑roasted cauliflower or a warm baguette makes the meal more substantial. For a festive touch, sprinkle toasted pine nuts and extra basil over the top before serving.
Storage Info
Leftover Storage
Allow the pasta to cool to room temperature, then transfer it to an airtight container. Store in the refrigerator for up to 3 days. For longer keeping, portion into freezer‑safe bags, flatten, and freeze for up to 2 months. Label with the date to track freshness.
Reheating Instructions
Reheat gently in a skillet over medium‑low heat, adding a splash of vegetable broth or water to loosen the sauce. Stir frequently until steaming hot, about 4‑5 minutes. In a microwave, cover the portion with a damp paper towel and heat on medium power for 1‑2 minutes, stirring halfway through. Finish with a pinch of fresh basil and extra Parmesan for revived flavor.
