Creamy Vegetarian Pasta With Veggies
This Creamy Vegetarian Pasta is a practical, vegetable-forward dinner that relies on a smooth cashew-based sauce rather than heavy dairy. By blending soaked raw cashews with standard pasta sauce, you create a velvety texture that coats penne and a variety of sautéed vegetables like broccoli, red bell peppers, and mushrooms.
As an editorial choice for busy weeknights, this recipe is designed to be efficient once your base ingredients are prepped. While the actual cooking time is approximately 30 minutes, the method requires a bit of forward-thinking regarding the cashews to ensure the sauce reaches the desired consistency. It serves as a reliable vegetable pasta dinner that is naturally vegan, provided you skip the optional parmesan garnish.

What You’ll Need
The success of this dish depends on the combination of fresh produce and the creaminess of the cashew-based sauce. Using penne pasta is recommended because its shape holds the weighted sauce and small vegetable pieces effectively.

- Penne pasta: 8 ounces provides the structural base for the dish.
- Olive oil: 1 tablespoon for sautéing the vegetables.
- Broccoli florets: 4 cups (about 250 grams), cut into bite-sized pieces.
- Red bell pepper: 1 large (150 grams), julienned for even cooking.
- Mushrooms: 1 heaping cup (100 grams), sliced.
- Quartered artichokes: One 14-ounce can, thoroughly drained.
- Cherry tomatoes: 1 cup (150 grams), halved to add a fresh finish.
- Salt and pepper: To taste.
- Pasta sauce: 1 1/2 cups of your preferred red sauce.
- Raw cashews: 3/4 to 1 cup, soaked until softened.
- For serving: Fresh basil and optional parmesan cheese (use vegan parmesan to maintain a creamy vegan pasta profile).
How to Make It
The cooking process involves boiling the pasta while simultaneously preparing the vegetables in a large skillet. Managing the timeline ensures that the sauce and vegetables are ready at the same time the pasta finishes cooking.
- Soak the raw cashews in a bowl of water overnight or for at least 4 hours. If you are short on time, cover them with water and microwave for 1–2 minutes until they are soft enough to blend.
- Bring a large pot of salted water to a boil. Cook the penne pasta according to the package instructions until it reaches an al dente texture.
- Before draining the pasta, reserve at least 2 tablespoons of the starchy pasta water to help emulsify the sauce later.
- In a high-speed blender, combine the pasta sauce and the drained, soaked cashews. Blend on high until the mixture is completely smooth and creamy.
- While the pasta water is coming to a boil, heat the olive oil in a large nonstick skillet over medium heat.
- Add the broccoli florets to the hot skillet. Season with salt and pepper and cook for 4–5 minutes, stirring occasionally.
- Incorporate the julienned red bell peppers and continue cooking for 3–4 minutes.
- Add the sliced mushrooms and another pinch of salt and pepper. Cook for an additional 3–4 minutes until the mushrooms have softened.
- Stir in the drained artichokes, the cooked pasta, the reserved pasta water, and the blended cashew pasta sauce.
- Mix everything thoroughly and allow the dish to warm through for 1–2 minutes. If the sauce appears too thick, stir in a little more pasta water.
- Gently fold in the halved cherry tomatoes just before serving.
- Top the pasta with fresh basil and serve immediately with optional bread or cheese.
Soak the Cashews First
To achieve a truly creamy vegetarian pasta, the texture of the cashews is the most critical factor. Raw cashews are quite hard, and without proper softening, the blender will leave small gritty bits in your sauce. For the best result, plan to soak your cashews in water for at least 4 hours or overnight.
If you find yourself needing to make this 30-minute dinner but forgot to soak the cashews, the microwave shortcut is a helpful editorial tip. By placing the cashews in a microwave-safe bowl, covering them with water, and heating them for 1 to 2 minutes, you can quickly soften the outer layers enough for a high-speed blender to process them into a smooth liquid.
Adjust the Sauce
The thickness of the cashew pasta sauce is easily customized based on the quantity of cashews you use. The recipe allows for 3/4 cup to 1 cup of soaked cashews. Using 3/4 cup produces a sauce that is lighter but still very creamy, while a full cup creates a much thicker, heavier coating for the penne.
Another essential tool for texture control is the pasta water. Because this sauce is vegetable-based and contains no dairy fats, it can thicken rapidly when it hits the hot pan. Reserving a small amount of the cooking water allows you to thin the sauce to your exact preference without diluting the flavor. Start with 2 tablespoons and add more only if the sauce feels too dry after mixing.
Cook the Veggies in Stages
To ensure every element of this vegetable pasta dinner has the correct bite, the vegetables must be added to the skillet in stages. Broccoli and mushrooms have very different cooking times, so following a specific order prevents the peppers from becoming mushy while the broccoli remains raw.
Begin with the broccoli, as it requires the most time to become tender-crisp. The peppers follow to soften slightly, and the mushrooms are added last so they can release their moisture without disappearing into the mix. The cherry tomatoes are only added at the very end; they should be just barely warmed through so they retain their shape and provide a burst of fresh flavor against the creamy sauce.

Freshness Notes
This dish is at its best immediately after assembly when the cashew pasta sauce is warm and fluid. Because cashew-based sauces tend to set and thicken as they cool, serving it right away ensures the smoothest mouthfeel. The addition of fresh basil at the end provides a necessary aromatic lift that complements the cooked vegetables.
Frequently Asked Questions
Is this creamy pasta vegan or vegetarian?
As written, the recipe is naturally vegan because the creaminess comes from blended cashews. It is considered a Creamy Vegetarian Pasta if you choose to serve it with standard parmesan cheese, but you can keep it strictly vegan by using a plant-based cheese alternative.
How long do cashews need to soak?
For the smoothest results, raw cashews should soak for at least 4 hours or overnight in room-temperature water. This ensures they blend completely into a cream without leaving a grainy texture in your sauce.
Can I use 3/4 cup or 1 cup of cashews?
You can use either amount depending on how thick you want the sauce to be. 3/4 cup is the preferred amount for a balanced consistency, while 1 cup will result in a much richer, thicker sauce.
How do I thin the sauce?
If the sauce becomes too thick once it hits the hot skillet, simply stir in a few extra tablespoons of the reserved pasta water. This helps maintain the creamy texture without changing the overall flavor profile of the dish.
Conclusion
This Creamy Vegetarian Pasta offers a practical way to enjoy a rich, satisfying meal without relying on dairy. By mastering the cashew soaking process and cooking your vegetables in stages, you can create a high-quality dinner in about 30 minutes of active time. Whether you use 3/4 cup for a lighter sauce or a full cup for extra thickness, the combination of penne, fresh broccoli, and savory mushrooms makes for a reliable weekday staple. Finish with fresh basil and enjoy a straightforward, vegetable-heavy meal.
