The key to a creamy sauce
If you’ve recently cut dairy out of your diet, I understand the struggle of not knowing what to use in cooking to make things creamy. Fortunately, there lots of amazing replacements these days to satisfy your creamy pasta cravings. There are a few key ingredients we will be using that will yield a super creamy red pepper sauce.
Cashews: Raw and soaked cashews are my go to ingredient to make any pasta sauce cream. I do have a slight intolerance to cashews, but I deal with pain after eating this pasta because it’s just so good.
Olive oil: A good quality olive oil is going to give this sauce depth of flavor and will help round out the creamy texture. You can omit this if you are oil-free, but it won’t be quite the same.
Almond milk: You can use any non-dairy milk in place of almond milk if needed. Just make sure it is both unflavored and unsweetened, we don’t want any hits of vanilla in this pasta!
How to make this recipe
First, add the cashews to a bowl of boiling hot water and soak them while you prep everything else. Next, you’ll want to chop the onion, peppers and peel the garlic.
Add them to a baking sheet lined with parchment paper and bake at 350 for 30 minutes. While those are roasting, bring a large pot of salted water to a boil and cook pasta according to package instructions. When it’s done, don’t rinse it, but drizzle with a bit if olive oil and toss around.
When the veggies are done, add them to a blender with the drained cashews and all remaining ingredients.
Process until smooth. Combine with the cooked pasta, top with fresh basil and enjoy!
Flavor tips
You don’t want to skimp on the onion or the garlic in this recipe. I recommend using 4 large, like really large, cloves of garlic or 6 smaller ones.
Always salt your pasta water! Generously! It will infuse a ton of flavor into the pasta while it cooks AND it even helps the sauce “stick” to the pasta better. Especially important if you’re using gluten free pasta
Frequently asked questions
Is it gluten free? Yes, the sauce is naturally gluten free! To keep this dish gluten free I used brown rice pasta, but any pasta will do! For extra protein you can use chickpea pasta or a legume based pasta.
Does it keep? Yes! Once prepared, this vegan roasted red pepper pasta will store in the fridge for about 3-5 days. To reheat, add the pasta to a pan with a splash of almond milk, oil or water to bring out the creaminess and reheat over low heat until warm.
You can also just pop it into a microwave safe bowl, add a drizzle of oil, then microwave for about 1 minute or until nice and hot.
Can I make it nut free? I have not tried this recipe with something in place of the cashews. You can try using tahini in place of cashews (about 1/4 cup tahini), but you will need to decrease the amount of milk to about 1/2 cup. I have not tried this myself, but I think it would work well! The flavor will be a bit different and more nutty, but still delicious!

Roasted Red Pepper Pasta
by: claire cary
Ingredients
- 16 ounces pasta of choice
- 2 large red bell peppers
- 1 large red onion
- 4 large cloves garlic
- 2 tbsp olive oil
- ½ cup raw cashews
- 3/4-1 cup plain unsweetened almond milk
- 1 tbsp arrowroot powder tapioca or cornstarch also work
- 2 tbsp nutritional yeast
- 1 tbsp tomato paste
- 1 tsp salt or to taste
- ¼ tsp red pepper flakes
- ¼ cup fresh basil
- Black pepper to taste
Instructions
- Add the cashews to a bowl and cover with boiling water. Set aside while you prep the remaining ingredients. If you have had trouble with cashew based sauces in the past, you can boil them in a pot for about 20 minutes while you prep all other ingredients which helps to soften them further.
- Preheat the oven to 350 degrees Fahrenheit.
- Peel the garlic, and chop the onion and bell peppers into large chunks.
- Place on a silicone baking mat or parchment paper and roast for 30 minutes.
- While the veggies are roasting, cook your pasta of choice.
- When the veggies are done, add to a high speed blender with the drained cashews and all remaining ingredients and process until completely smooth. Start with 3/4 cup of milk and add more as needed to thin it out.
- Stir the sauce into the cooked pasta, and top with fresh basil if desired!
Alison says
I used unsweetened oat milk instead of almond milk and it turned out very tasty. The family loved it so this recipe will be added to my roster of pasta sauces. It is easy to make so perfect for a weeknight meal.
Claire Cary says
Perfect, so glad your family enjoyed it!
Jahnvi says
So so so good, I did a little dance after first bite! My favorite sauce with chickpea pasta. Thank you 🙂
Claire Cary says
Love that, thank you!
Anne says
I wonder what went wrong, because my dish tasted really bland. I didn’t have nutritional yeast, so I googled for substitudes and used dried porcini mushrooms. I wonder if I should have used soy sauce instead.
Claire Cary says
Hmm, I’ve never heard of using porcini mushrooms in place of nutritional yeast. I’d definitely give it a try with the nutritional yeast next time, it’s key for that bit of cheesy flavor! You can always add more salt, pepper or red pepper flakes as well.
Heather says
Should the peppers, onion and garlic be tossed in the oil and salt prior to roasting? It doesn’t really say in the recipe directions…
Claire Cary says
You can, but there’s not really a need. The oil, salt, pepper get added later.
Aarti says
Is this sauce freezer friendly?
Claire Cary says
I haven’t tried it, but it should be fine in freezer for up to 2 months.
Jamie says
This is A. MAZING. Tastes cheesy, creamy, and rich–with just the right tang from crushed red pepper and the veggies. Filling, too. Home run!
Claire Cary says
Thank you, Jamie!
MEGHAN says
I’m new to vegan recipes. I don’t know if I could go completely vegan, because it’s so time consuming. However, this recipe is so easy and literally gourmet. I doubled the recipe and bought fresh basil and had it for 7 nights in a row! It is delish! I love spice so I added (with the double recipe) 1 t of red pepper. And each night I had it, I added about 1 C of almond milk to thin it out. This is by far my fav recipe. I’m planning to make it tomorrow for my mom who is a “Minnesota” meat lover, but I know she will love it. Thanks so much for posting. This will be my staple recipe forever!!
Claire Cary says
Amazing, hope your mom loves it!
Christy says
It was really good! I made mine without the cashews (because I have a tree nut allergy) and used extra creamy oatmilk instead of almond milk and it still had great flavor! Plus, when you make it the way I did, it’s VERY low in points for WW!
Leah says
This pasta was SO GOOD! I made it for my family and everyone loved it. I doubled it so there was extra and they’re already looking forward to having it for lunch tomorrow! Will definitely be making again, thanks for the recipe 🙂
Harshini Deoroop says
I didn’t have almond milk so can I used water or coconut milk
Claire Cary says
Yes I would just use water!
Rachel says
I was really excited about this recipe! The only thing is that if didn’t come out quite as creamy as i was hoping. I’m not quite sure what I did wrong (maybe didn’t blend enough) but I ended up using 1 cup of non dairy milk, but my only other thought was to add more. Regardless, the taste was AMAZING! I’ll definitely try it again!
Claire Cary says
oh no sorry to hear that! I would try either boiling the cashews so they’re really soft, and/or blending the sauce for longer! Hopefully that does the trick!
Henna says
This was so delicious!! I will definitely be making this over and over again! I will probably bump up the spice level just a bit, but other than that – heaven!
Claire Cary says
So glad you liked it! I’m kind of a wimp when it comes to spice LOL so feel free to add more red pepper flakes for a bit of a kick!
M says
Hey there I only have unsweetened coconut milk and soya milk here but I’d still like to try, do you feel one would be better than the other?
Claire Cary says
Is your coconut milk from a can or a carton? If from a carton, that would be fine, but I think the soy milk would probably be best as long as it’s unsweetened!
Shanna says
Can i leave out the cashews all together and just add a bit more arrowroot or something else to thicken?
Claire Cary says
Yes you can just leave them out and then add more arrowroot as needed to thicken! It won’t be quite as rich/creamy this way though.
Sarah says
This sauce is so creamy and has so much flavor. I love the base alone but I enjoyed playing around with it to make it match my taste. I added a can of tomatoes, Italian seasoning, salt, pepper and red pepper flakes. I added zucchini, squash and artichokes for some texture and it was delicious!
Claire Cary says
So glad you were able to make it your own! Sounds delish with those additions
Ruby says
Loved this recipe. The pasta was so creamy and yummy.
Claire Cary says
Thank you Ruby! It’s one of my favorites 🙂
Alyssa says
This recipe was easy to make and was delicious. It was very creamy! The only trouble I had was that I only have a Nutribullet, so it didn’t blend as smoothly as I would have liked, but it was still good!
Claire Cary says
Thanks Alyssa! Next time you can try subbing the cashews for cashew butter, it should make it much creamier when you blend it 🙂
Naomi says
This looks great! Do you think the taste would be seriously compromised if I cheated and used roasted red peppers from a jar?
Claire Cary says
It’s not going to have quite the same flavor, but it might work! You definitely don’t want to leave out the roasted onion or garlic though, so may as well just throw the fresh peppers in there too!
Olivia says
I love this. So good to have for dinner. This is so easy to heat up and this is so flavorful!
Claire Cary says
Yes! It heats up so well, glad you liked it 🙂
Elle says
What kind of blender did you use to get the sauce so smooth? I have a Ninja and it came out super lumpy, no matter how long I blended it.
Claire Cary says
I have a vitamix! Did you soak the cashews? That should make it easier to blend! A food processor could also work
Elle says
I did. Boiled water, then poured it into the bowl so it covered the cashews and let it sit while I chopped and roasted the veggies. I even tried using an immersion blender after the regular blender. The cashews were raw.
Claire Cary says
An immersion blender is unfortunately not powerful enough for cashews, but you can try subbing the whole cashews for 2-4 tbsp cashew butter next time! You should get about the same result 🙂 Sorry for the trouble, a high speed blender is necessary for this recipe.
Amanda says
I boiled my cashews the whole time the peppers roasted instead of setting them in a bowl of boiled water and it worked in my Nutribullet. I’ve avoided cashew sauces in the past because they turned out gritty for me but this method solved that problem. The sauce was creamy and delicious-even my extremely picky three year old gobbled it up. Hope you try it again and have better results!
Claire Cary says
Such a good idea! I’ll make note of that for other readers who make the recipe. Thanks for the feedback and so glad you enjoyed it!
Kris says
Delicious and easy! I completely forgot to do the last step and poured the sauce straight from the blender over my pasta and it was still very tasty. I added some salt, pepper and hot pepper flakes before blending — I like heat in almost all of my food. Sautéed up some asparagus and mushrooms to mix in, and used plant-based higher protein penne.
This was so perfectly easy – will it freeze well? I’d love to double a batch next time I make it.
Claire Cary says
YUM! I love asparagus mixed in with this! I do think it would freeze well, however, certain gluten free pastas/legume based pastas don’t hold up very well so I’m not sure how well that would work. The sauce on it’s own would definitely be ok to freeze though! Let me know how it turns out if you try it 🙂
Joan says
Loooooove this recipe. It’s one of my go to’s that I just keep making. I add spinach, asparagus and cannellini beans to it usually. So easy to make! Thanks so much!! 😁
Claire Cary says
Thanks Joan! So happy it’s such a favorite! If you don’t mind leaving a star rating along with your review next time, it really helps us out:)
Garimaa says
Very tasty!
Claire Cary says
Thanks Garimaa! So glad you liked it 🙂
Jamet says
I only have original almond milk which has a bit of a vanilla aftertaste can you use that for this recipe?
Claire Cary says
I highly recommend using plain, unsweetened milk for this recipe. I’d check the ingredients on yours to make sure there is no added sugar. Otherwise, it may not turn out very well!
Elizabeth says
Just made this tonight. It was quick and super tasty. I added some spinach for some greens. This is the second recipe I’ve tried from your blog / instagram and they have both been so flavorful. So much that my teenage daughter not only eats it but says she will eat again. Thank you for posting them 🙂
Claire Cary says
That sounds delish! I’m so glad you’ve been liking the recipes!
Melissa says
I made this tonight, served with choice of Seitan “sausage” or regular Italian sausage for the carnivores in the house. Made a great one-dish meal.
Claire Cary says
Hi Melissa! I’m so glad it was enjoyed by all types of eaters! Thanks so much for trying it 🙂
Hanne says
This looks delicious. Roasted red peppers are amazingly versatile. I will be making this recipe soon.
Claire Cary says
Thanks so much Hanne! Let me know how you like it 🙂
Kelli says
I’m new to cooking Vegan, and my very first recipe called for adding nutritional yeast at the end. I thought it totally ruined the flavor of the meal. Does the yest do anything except fool people into thinking it’s ‘creamier’? Do you think this recipe would be okay with out? I’m so sorry, but I really didn’t like it! Thanks for any advice!
Claire Cary says
You can totally just leave it out if you don’t like it! It does give a slightly “cheesy” flavor, but I’ve made this recipe without the nutritional yeast many times, and it’s still delicious! Let me know what you think if you try it 🙂
Leslie says
Such a delicious recipe- thanks for sharing!
Claire Cary says
So happy you liked it!
Grace Cary says
Love this!

Thanks, Grace!
