Creamy Roasted Red Pepper Pasta
After I posted two new rice recipes in a row, I thought it’s time for a new pasta dish recipe! One which you might like if you are a fan of creamy and flavorful sauces. I know, I am! I love everything saucy and flavorful. That’s why I created this delicious vegan roasted red pepper pasta.
You should give this recipe a try because it is:
- A tasty meat-free weeknight dinner
- Creamy, flavorful, and spicy (if you want to add red pepper flakes)
- Easy to make with simple ingredients
How To Make The Best Roasted Red Pepper Pasta?
- First, chop the veggies. Slice the peppers into strips, quarter the onion, and peel the garlic. Transfer the veggies onto a lined baking sheet and roast them in the oven for 15-20 minutes:
- At the same time, cook your favorite pasta. You can use regular wheat pasta or gluten-free pasta.
- Meanwhile, measure all other sauce ingredients.
- Once the veggies are nicely roasted, add them to a blender or food processor.
- Add all other sauce ingredients and blend on high speed for a few minutes until very smooth and creamy
- Heat up the sauce in a pot or skillet, toss in the cooked pasta and you are done!
This recipe is so easy to make with simple ingredients which you might already have at home. The main ingredients are peppers and since this is a roasted red pepper pasta, I would suggest using red bell peppers. As you might have noticed, I only had one red bell pepper, that’s why I used one orange bell pepper, haha.
I used cashew butter which makes the sauce super creamy. You can use 1/3 cup of cashews instead of cashew butter though. Make sure to soak the cashew nuts in hot water for about 20 minutes, this way they blend much easier and smoother.
Nutritional yeast flakes add a cheesy umami taste, however, you can leave them out. The sauce will still taste great but I think it’s even better with nutritional yeast. I order nutritional yeast flakes online but they are available in most supermarkets. If you can’t find them, you could use 1 tbsp of soy sauce instead, which will also add an umami taste.
If you want to make the recipe low-carb, simply use spiralized zucchini or squash instead of pasta!
How To Store Roasted Red Pepper Alfredo?
This recipe serves 2-3 people. You can double the recipe and store leftovers covered in the fridge for up to 4 days. You can simply reheat them in a pot with a splash of plant-based milk.
Creamy Roasted Red Pepper Pasta Sauce
The cashew butter and plant-based milk make the sauce creamy and delicious. You can use any plant-based milk of choice, for example, almond milk, cashew milk, coconut milk, or soy milk. I used canned coconut milk because I love the creaminess it adds.
This Creamy Roasted Red Pepper Alfredo Sauce Is:
- Vegan (meat-free, dairy-free)

- Preheat oven to 375 degrees Fahrenheit (190 degrees Celsius) and line a baking sheet with parchment paper.
- Slice the peppers into strips, quarter the onion, and peel the garlic cloves. Transfer the veggies onto the baking sheet (check the photos in the blog post above).
- You can drizzle some oil on top or roast the veggies without oil in the oven for about 15-20 minutes.
- At the same time cook your favorite pasta as per the instructions on the package.
- Meanwhile, measure the other ingredients.

- I used one red bell pepper and one orange bell pepper. Feel free to use only red bell peppers.
- You can use any plant-based milk of choice, e.g. almond milk, soy milk, cashew milk, etc.). I used canned coconut milk for extra creaminess.
- The cashew butter will make the sauce creamy and delicious. If you need a nut-free alternative, try tahini (keep in mind that it has a slightly bitter taste) or sunflower seed butter.
