Creamy Vegan Red Pepper Pasta
Ingredients
- 1 lb rigatoni pasta
- 2-3 cups cherry tomatoes
- 1 tablespoon olive oil
- salt and pepper
- 1 1/4 cup cashews
- 1/4 cup olive oil
- 1 1/2 cups water
- 1 large roasted red pepper
- 1 clove garlic
- 2 tablespoons nutritional yeast
Instructions
- Cook rigatoni pasta according to package directions until al dente.
- Preheat your broiler. Toss cherry tomatoes with 1 tablespoon olive oil, salt, and pepper on a baking sheet. Broil for 10-15 minutes until blistered and juicy.
- While the pasta cooks and tomatoes broil, blend sauce ingredients: cashews, 1/4 cup olive oil, 1 1/2 cups water, 1 large roasted red pepper, 1 clove garlic, and 2 tablespoons nutritional yeast in a blender until very smooth and creamy.
- Drain the cooked pasta, reserving about 1/2 cup of the pasta water.
- Pour the creamy red pepper sauce over the hot pasta (off the heat). Stir well to coat every piece. If the sauce is too thick, add a splash of the reserved pasta water until it clings beautifully.
- Serve immediately, topping the pasta with the blistered tomatoes. Garnish with fresh herbs, extra salt, and pepper if desired.
Notes
– Ensure your cashews are soaked (if not using a high-speed blender) for the smoothest sauce.
– Reserve pasta water! It’s liquid gold for adjusting sauce consistency.
– Use good quality roasted red peppers for the best flavor base. Allergens: Tree nuts, Wheat. Nutrition information is an estimate, calculated automatically. Values vary with brands, substitutions and portion sizes.
The technique that makes it
The magic behind this creamy vegan red pepper pasta lies in the cashew cream sauce. The key is to properly soak the cashews. Soaking softens them, allowing them to blend into an incredibly smooth and luxurious sauce, mimicking the richness of dairy cream without any animal products. For the best results, soak raw, unsalted cashews in hot water for at least 30 minutes, or in cold water for 4-8 hours (or overnight). If you’re short on time, a quick soak in boiling water for 10-15 minutes can also work, though the texture might be slightly less silky. After soaking, it’s crucial to drain the cashews thoroughly before blending. This prevents the sauce from becoming too watery. The combination of soaked cashews, water, roasted red pepper for sweetness and color, nutritional yeast for a cheesy depth, and garlic for a pungent kick, creates a harmonious flavor profile. Blending until completely smooth is non-negotiable; any grittiness will detract from the overall experience of this red pepper pasta.
Troubleshooting
- Sauce is too thick: If your cashew cream sauce is too thick after blending, add more water, one tablespoon at a time, until it reaches your desired consistency. Be careful not to add too much at once.
- Sauce is too thin: If the sauce is too thin, it likely means too much liquid was added during blending. You can try to thicken it by simmering it gently in the pan for a few minutes, allowing some of the water to evaporate. Alternatively, blend in a few more soaked cashews.
- Sauce is bland: This red pepper pasta relies on balanced flavors. If it tastes bland, it might need more salt, pepper, or nutritional yeast. A squeeze of lemon juice can also brighten the flavors. Ensure your roasted red pepper is flavorful; sometimes store-bought ones can be mild.
- Pasta is clumpy: Ensure you’re cooking your pasta in plenty of salted boiling water and stirring it occasionally. After draining, toss it immediately with a little bit of the sauce or olive oil to prevent sticking.
Substitutions
- Cashews: For a nut-free version, soaked sunflower seeds (about 1.5 cups) can be used, though the flavor will be slightly different and the color may be less bright. Silken tofu (about 1.5 cups) is another option for a creamy base, but it will alter the flavor profile significantly.
- Roasted Red Pepper: If you don’t have pre-roasted red peppers, you can roast your own bell peppers under a broiler or on a grill until the skin is blackened, then steam them in a covered bowl before peeling and deseeding. Alternatively, jarred roasted red peppers in brine (drained) are a convenient substitute.
- Nutritional Yeast: While it provides a distinct cheesy, umami flavor, if unavailable, you can omit it, but the sauce will lack that savory depth. A small amount of Dijon mustard can add a subtle tang.
- Rigatoni: Any short, sturdy pasta shape like penne, fusilli, or ziti will work well. The ridges and hollows help to hold the creamy sauce effectively.
Pro tips
- For an extra cheesy flavor, don’t skip the nutritional yeast.
- Ensure your cashews are soaked (if not using a high-speed blender) for the smoothest sauce.
- Reserve pasta water! It’s liquid gold for adjusting sauce consistency.
- Use good quality roasted red peppers for the best flavor base.
Enjoy this fresh and deeply satisfying vegan red pepper pasta. It’s a versatile dish that’s perfect for any occasion.

Frequently asked questions
Can I use different vegetables in vegan red pepper pasta?
Absolutely! Zucchini, spinach, mushrooms, or even broccoli florets would be delicious additions. Sauté them with the onions and garlic before adding the peppers. Adjust cooking times based on the vegetables you choose to ensure they are tender but not mushy.
How do I store leftover creamy vegan red pepper pasta?
Let the pasta cool completely before transferring it to an airtight container. Store in the refrigerator for up to 3-4 days. The sauce may thicken upon chilling; you can loosen it with a splash of water or unsweetened plant-based milk when reheating.
What can I serve with vegan red pepper pasta?
This pasta is wonderful on its own, but it pairs well with a simple side salad dressed with a light vinaigrette. Garlic bread or crusty bread for dipping into the sauce is also a great option. For added protein, consider serving with pan-seared tofu or white beans.
How do I make vegan red pepper pasta thicker or thinner?
To thicken, simmer the sauce uncovered for a few extra minutes to allow excess liquid to evaporate. For a thinner sauce, stir in a little more unsweetened plant-based milk or pasta water until you reach your desired consistency. Avoid adding too much liquid at once.
