Ingredients
Fresh, high‑quality ingredients are the backbone of this dish. The roasted red peppers give the sauce its signature color and smoky sweetness, while the cashews provide a dairy‑free creaminess that coats each noodle. Whole‑grain pasta adds a nutty bite and extra fiber, and the herbs finish the plate with a burst of freshness. Together these components create a balanced, satisfying meal that feels both wholesome and indulgent.
Pasta & Base
- 12 oz (340 g) whole‑grain penne
- 1 tablespoon olive oil
Roasted Red Pepper Sauce
- 3 large red bell peppers (or 2 cups jarred roasted peppers)
- ½ cup raw cashews, soaked 4 hrs
- 2 cloves garlic, minced
- 1 tsp smoked paprika
- ¼ cup vegetable broth (or water)
- 1 tbsp lemon juice
Seasonings & Garnish
- Salt and freshly ground black pepper, to taste
- ¼ cup fresh basil, torn
- 2 tbsp grated Pecorino Romano (optional)
The harmony of these ingredients is what makes the sauce sing. Roasting concentrates the peppers’ natural sugars, while the soaked cashews turn into a silky base without dairy. Garlic and smoked paprika add aromatic depth, and a splash of lemon juice lifts the richness with bright acidity. Finishing with basil and a sprinkle of cheese adds a fragrant, salty finish that ties the whole dish together.
Step-by-Step Instructions
Roasting the Peppers
Preheat your oven to 450°F (230°C). Slice the red peppers in half, remove seeds, and place them skin‑side up on a baking sheet lined with parchment. Roast for 20‑25 minutes, or until the skins blister and turn black. Transfer to a bowl, cover with plastic wrap for 5 minutes, then peel off the skins. The charred skins add smoky depth, while the tender flesh blends smoothly.
Preparing the Sauce
While the peppers cool, bring a pot of salted water to a boil and cook the penne according to package directions until al dente (about 9‑11 minutes). Drain, reserving ½ cup of pasta water. In a high‑speed blender, combine the roasted peppers, soaked cashews, garlic, smoked paprika, vegetable broth, lemon juice, and a pinch of salt. Blend until completely smooth; the mixture should be thick yet pourable. Adding a splash of the reserved pasta water later will help loosen the sauce without thinning it.
Finishing the Pasta
Heat the olive oil in a large skillet over medium heat. Pour the blended sauce into the pan, stirring constantly. Simmer gently for 4‑5 minutes, allowing the flavors to meld and the sauce to thicken enough to coat the back of a spoon. Toss the cooked penne into the sauce, adding a little reserved pasta water if needed to achieve a glossy coating. Season with salt and pepper, then fold in the fresh basil and optional Pecorino. Serve immediately, garnished with an extra drizzle of olive oil and a sprinkle of basil.
Detailed Cooking Steps
- Roast the peppers. Place halved peppers on a baking sheet, skin side up, and roast at 450°F for 20‑25 minutes. The skin should blister and blacken, indicating the sugars have caramelized for maximum flavor.
- Peel & cool. Transfer the hot peppers to a bowl, cover, and let steam for 5 minutes. This loosens the skins, making them easy to peel without tearing the flesh.
- Blend the sauce. Combine peeled peppers, soaked cashews, garlic, smoked paprika, broth, and lemon juice in a blender. Process until silky; a smooth texture ensures the sauce clings to every noodle.
- Cook the pasta. Boil water, add a generous pinch of salt, and cook penne until al dente. Reserve ½ cup of cooking water before draining.
- Simmer the sauce. Warm olive oil in a skillet, pour in the blended mixture, and simmer for 4‑5 minutes. This step reduces the raw edge of the cashews and melds the smoky notes.
- Combine & finish. Add the drained pasta to the sauce, toss, and adjust consistency with reserved pasta water. Finish with fresh basil, optional cheese, and a final pinch of salt and pepper.
Tips & Tricks
Perfecting the Recipe
Soak cashews properly: Soak raw cashews for at least 4 hours (or 15 minutes in hot water) to achieve a truly creamy texture without a gritty mouthfeel.
Use high heat for roasting: A scorching oven ensures the skins blister quickly, preserving the pepper’s natural sweetness while adding a subtle char.
Reserve pasta water: The starchy water helps emulsify the sauce, giving it a glossy finish that clings to each noodle.
Finish with fresh herbs: Adding basil at the end preserves its bright flavor and prevents it from wilting into the heat.
Flavor Enhancements
For an extra layer of complexity, stir in a pinch of red‑pepper flakes for gentle heat, or drizzle a teaspoon of smoked olive oil just before serving. A splash of sherry vinegar adds a subtle tang that brightens the creamy base without overpowering the roasted pepper flavor.
Common Mistakes to Avoid
Avoid over‑blending the sauce; a few seconds too long can turn the cashew base watery. Also, don’t skip the resting time for the roasted peppers—covering them lets the skins loosen, saving you from a frustrating peeling battle.
Pro Tips
Blend in batches: If your blender is small, blend the peppers first, then add cashews and liquids. This prevents the motor from overheating.
Season gradually: Taste the sauce after each addition of salt, pepper, or lemon juice. This ensures balanced seasoning without over‑salting.
Use a heavy‑bottomed skillet: Even heat distribution prevents the sauce from scorching, preserving its delicate flavor.
Finish with a pat of butter (optional): Swirling in a tablespoon of butter at the very end adds a luxurious sheen and rounds out the flavor.
Variations
Ingredient Swaps
Replace whole‑grain penne with gluten‑free rice pasta or spiralized zucchini for a lighter option. Swap cashews for soaked almonds or silken tofu to change the cream base. For a smoky twist, add a teaspoon of chipotle in adobo instead of smoked paprika. Each swap keeps the core flavor while tailoring texture and dietary needs.
Dietary Adjustments
To make the dish fully vegan, omit the Pecorino and use nutritional yeast for a cheesy note. For a low‑carb version, serve the sauce over spaghetti squash or shirataki noodles. Gluten‑free diners can simply use certified gluten‑free pasta and ensure the broth is also gluten‑free.
Serving Suggestions
Pair the pasta with a crisp arugula salad dressed in lemon vinaigrette, or serve alongside roasted garlic bread for extra soak‑up power. A side of grilled asparagus or sautéed spinach adds a green contrast, while a glass of chilled Sauvignon Blanc highlights the dish’s bright acidity.
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 the sauce and pasta separately, freeze in freezer‑safe bags, and use within 2‑3 months. This prevents the noodles from becoming mushy.
Reheating Instructions
Reheat gently in a skillet over medium‑low heat, adding a splash of broth or water to revive the sauce’s creaminess. Alternatively, microwave in a covered bowl for 1‑2 minutes, stirring halfway through. Avoid high heat, which can cause the sauce to separate and the pasta to dry out.
