This creamy vegan roasted red pepper pasta is full of flavor, but possibly the best part about it is that it only takes 20 minutes. Yep – well under 30 minutes for tender pasta swimming in a creamy, dreamy, and incredibly simple roasted red pepper sauce.
If you follow anyone from Seattle on social media, I’m sure you’ve heard all about the crazy amount of snow we’ve been getting. At our house, we’ve been snowed in for the majority of the past eleven days, and over the last day and a half it dumped probably another foot (!!!) of snow. This amount of snow is almost unheard of around here, and I’d go so far as to say that most of us were wildly unprepared for it.

We’ve been using garden shovels to scoop snow (why have a snow shovel when we only need it once every 10 years?! Oh right, because it would have been really nice to have one for #snowmageddon!) And only yesterday did it finally occur to us that we should knock snow off of flat roofs and other surfaces, drooping tree branches, and our (previously thriving) garden vines.
Meanwhile, our grocery stash is growing a bit slim. I really wanted to come up with a marvelous Valentine’s Day recipe for y’all, and I’ve been working on an amazing, almost-there raspberry sweet roll recipe. But I don’t have it quite right yet and I ran out of the ingredients to continue testing it.
Luckily, I had just enough groceries in the pantry to make and photograph this Creamy Vegan Roasted Red Pepper Pasta, a favorite dinner of late. It used up my last 1/2 of an onion and the basil in the fridge was definitely a little worse for the wear, but I managed to pull it off.

I really didn’t consider this one a Valentine’s Day recipe because instead of being red or pink it’s kind of more of an orange. But if you eat by candlelight and serve it up with some heart-shaped bread or something (is there such a thing? There should be), I think it’ll totally work.
So what do we have here? Pasta of course. I like rotini for this one. One with some nooks and crannies is desirable here because it’ll grab and cradle all of that delicious sauce.
And that sauce, my friends. It’s so deceptively simple. Sauteed onion, oregano, and garlic. A bit of tomato paste. A jar of roasted red peppers. Some cashews for their signature glorious creaminess. Puree until smooth and luscious, aaaand done.

This recipe comes together in about 20 minutes, which in my book makes it a contender for many a future weeknight dinner – not just V-Day.

Even if it’s more orange than red or pink, I love this recipe. And Valentine’s Day is all about love, right? I know, I know … it’s a stretch. Either way, Happy Valentine’s Day, and stay warm out there!

Creamy Vegan Roasted Red Pepper Pasta
Ingredients
- 8 ounces rotini pasta (or pasta of your choice)
- 1 tablespoon olive oil
- 1/2 medium yellow onion, diced (about 1 cup diced)
- 1 teaspoon dried oregano
- 2 medium cloves garlic (minced)
- 2 tablespoons tomato paste
- 1/2 cup water
- 1 (15-ounce) jar roasted red peppers, drained
- 1/3 cup raw whole cashews*
- 1/2 teaspoon kosher salt + more to taste
- 1/4 teaspoon freshly ground black pepper + more to taste
- 4-5 fresh basil leaves (chiffonaded)
Equipment
- High speed blender (like Blendtec or Vitamix)
Instructions
- Place a large pot of water on the stove to boil. Once boiling, add the pasta. Cook according to package instructions (usually about 8-10 minutes). Drain and set aside.
- While the pasta boils, set a medium saucepan over low heat. When hot, add the olive oil. Add the onion and oregano. Cook, stirring occasionally, until softened and beginning to get translucent, about 8 minutes. Add the garlic and cook, stirring frequently, for one more minute. Add the tomato paste and cook until warmed through. Pour in 1/2 cup water and stir to bring up all of the bits of everything.
- Pour the sautéed onion mixture into the blender. Add drained roasted red peppers, cashews, 1/2 teaspoon salt, and 1/4 teaspoon pepper. Puree until silky smooth, 2-3 minutes. If the sauce is too thick to puree, add a bit more water, a tablespoon at a time.
- Return the pasta to the pot you cooked it in or to the saute pan – whichever is biggest! Place over low heat. Add sauce. Stir gently and cook just until warmed through, 1-2 minutes.
- Taste and add more salt and pepper if desired.
- Sprinkle basil over the top and serve!
Could make a heart shaped garnish with a couple of red pepper strips
Cute! Love that idea!
This looks great – and with Lent on its way, I can use some fresh vegan ideas! Thanks so much for sharing : )
Could you provide the calorie content for this recipe? Sounds delicious, and easy. Thanks.
Hello, Kare, I tried this tonight and it was delicious! I love that it’s relatively low-calorie, and it was so creamy! Thanks for the great recipe!
I’m so glad you liked it! Thanks so much for coming back and reviewing the recipe. 🙂
I wanted to like this so much!!!! But honestly, it was a little bland for me. I ended up really salt and peppering it up and even adding some red pepper flakes for a bit of a kick.
I’m sorry this one wasn’t for you! I tend to call for lower amounts of salt and pepper initially and then suggest adding salt and pepper to taste since everyones’ salt/pepper tolerances vary – so that could have contributed.
Is it 1/2 cup or 1 cup of medium yellow onion?
Can you freeze this?
Pasta can be tricky; instead of freezing the whole thing, I would be apt to make the sauce and just freeze that, then thaw and toss with freshly cooked pasta.
Just made for the 4th or 5th time since discovering at the beginning of quarantine, so yum! Tonight I garnished mine (because I’m not vegan) with some goat cheese and it was wonderful!
This is my husband’s new favorite meal. Satisfying and full of flavor. Thank you for sharing!
Just made this and it was perfect! Thank u for sharing
This was SUPER yummy & filling! I used Trader Joe’s cauliflower gnocchi (2 bags worth for the amount of sauce in this recipe). I roasted broccoli and had that on the side 🙂
Oh gosh, I think I need a trip to TJ’s – cauliflower gnocchi sounds so good! Thanks so much for coming back to leave a review. I’m happy this was a hit for you!
Hi. Does the recipe still work well without the cashews? Thanks :))
Cashews are key for creaminess. You could try heavy whipping cream or full-fat coconut milk maybe?
Hi! Wondering how long this will keep in the fridge?
