I’m sensing a new theme emerging in my weeknight cooking: vegan pasta sauces made in the blender. It all started with my very craveable cashew alfredo sauce, which has been a family staple for years.
But then I made my green pasta, and my vegan mac and cheese (also with silken tofu!) and now I realize that this just might be one of the easiest ways to put a nutritious meal on the table with minimal effort. Which is probably why I love it so much, because I’m a very lazy weeknight cook!
You just boil your favourite pasta, whip the sauce up in the blender, and if need be, add an extra side of roasted veggies or double down on the protein by opening a can of some creamy white beans. Et voila! A balanced, comforting vegan dinner without all the fuss.
Silken tofu is an incredible ingredient: ultra smooth and milder in the flavour than typical tofu, it can be used as a substitute for cream in plant-based recipes because it blends like a DREAM. It lends a creamy richness to any pasta sauce as well as a little boost of protein. Which, as a plant-based dietitian, we should probably talk about as I’m seeing some misleading information on blogs about just how much protein silken tofu has.
FAQ: does silken tofu have a lot of protein?
Silken tofu is an ultra smooth type of tofu that is higher in water content than typical firm or extra firm tofu, so it’s not as protein-dense. The local brand I use, Sunrise, has about 4g of protein per ⅓ cup (85g). If you have access to firm or extra firm silken tofu at your store, that increases protein a bit, about 6-7 grams. So it’s a nice boost, but not a lot of protein on it’s own.
I see a lot of blogs claiming that silken tofu pasta sauces are “high in protein” which is why you want to be careful with nutrition information on the internet (that is not written by an actual dietitian!). I wouldn’t say that 6-7 grams is high. 20 grams of protein? That’s high!
And yep, when served with pasta, this silken tofu pasta sauce will net you a high protein meal, without adding additional protein to this recipe. The combination of this sauce plus two cups of cooked pasta will net you 21 grams of plant-based protein. I bet you didn’t realize that cooked pasta contains a whopping 8.6 grams of protein per cup! And that’s before you swap in a higher protein pasta like a chickpea-based pasta OR add on a protein like grilled tofu or white beans.
How to make this creamy red pepper silken tofu pasta sauce
This sauce couldn’t be easier: in just 5 minutes, you’ll blend up silken tofu and some pantry staples for a no cook, no chop sauce that will dress a full pound of pasta! Here’s how to do it:
Step One: gather your ingredients. You’ll need a 12-14 oz package of silken tofu, jarred (or leftover) roasted red peppers, nutritional yeast, garlic powder, thyme, lemon juice, salt, smoked paprika and pepper.
Step Two: throw ALL those ingredients into your blender. You don’t even need a high speed blender for this one! Blend on low until everything is broken down, then slowly increase to medium high and blend until smooth, about 1-2 minutes total. You might need to scrape it down once.
Step Three: taste, adjust salt as needed. Because there is variation in the flavour of jarred red peppers, you can adjust to your taste. Tasting too acidic? Just a ½ teaspoon of sugar will help balance it. Need more umami? Try an extra shake of nutritional yeast.
Step Four: toss with hot pasta and serve. I find depending on the shape of the pasta, and how saucy you like it, you might have a bit more sauce than you need. Pour it into a jar and save it in the fridge. It’s great for when you reheat leftovers, as the sauce dries up a bit. You can also use it as a dipping sauce.

Where can I get the bean soup recipe
There is a search bar in the upper right hand corner of the website! Just pop “brothy beans” into the search bar…
This was so easy to make. Didn’t have a jar of roasted red peppers so just chopped up two fresh ones and roasted with some olive oil in the toaster oven for 20 min. Also, kid approved! 😁
Yay, I’m so glad!!! And that’s such a good tip to just roast up some peppers of your own if you don’t have any jarred ones. Thanks Michelle 🙂
Desiree – made this last night and we loved it. I had some fresh basil which I blended in for fun. Trial run for guests this weekend – it’s a win! Thank you.
I am SO glad you liked it Anita! Hope your guests do too 🙂
I made this with frozen roasted red peppers…I thought they were bell peppers but they were mostly jalapeños! So it was very spicy! I wonder if this pasta should have been tossed with a knob of butter as for the mac n cheese? The leftovers benefited from this addition. The leftover sauce was indeed a great sauce for burritos the next day.
Ouch!! A red jalepeno sauce would be VERY spicy ha ha. And the addition of butter would be absolutely delicious too. Hope you like the sauce with real bell peppers next 🙂
I’m obsessed with this sauce, new go-to, especially for summer. I’m allergic to soy, so I used extra firm pumfu (tofu made from pumpkin seeds!) and it worked great. My blender had some trouble when I tried to blend on high, but a little water helped it out, and I was on my way to silky-smooth sauce in no time. I love that punchy roasted red pepper flavor! Thanks so much for this recipe, 11/10 for sure.
Okay what??? I need to find this pumpkin seed tofu, how cool! May I ask the brand??
easy and tastes great!
I’m so glad!!
I tried this last night and I was overwhelmed by the red pepper taste. I feel like it needs something else to balance it out. I love the technique. I just wish I would’ve liked the dish more. And I love red peppers.
Hi Susan,
Sorry to hear it – it’s definitely a very flavourful sauce. If you want to try again, a couple of options: one, use just 1/2 cup red pepper (make sure to pat it dry very well if using jarred peppers to minimize vinegar) OR add 1/4 cup of cashews to the blender. This recipe doesn’t have a lot of fat so the extra cashews will help make it creamier and richer and dilute the red pepper.
Hope this helps,
Desiree
Instead of making people go back to the blog in step 2 of instructions, why don’t you just add it to the printed version?
Hi! Great point…I didn’t want to unnecessarily complicate the instructions but honestly, I didn’t think about the situation where someone might not have read the post itself and it working from the printed version. I’m gonna pop those notes into the notes section on the recipe card so it prints 🙂
Can leftover sauce be frozen?
Hi Bernadette,
I suspect that it absolutely can…it will most definitely separate upon thawing bit a quick reblend should fix that!
How many servings is this please. I am. Loki g for one with leftovers!!
Thanks Valerie
Hi Valerie,
I would say that this is enough to cover a package of pasta, so four to six servings!
Just made this and did half recipe for myself. Loved it and so easy and had an arugula salad with it . Enough for 2 more meals.
Thanks
I am so glad you liked it Valerie!! Thank you for letting us know 🙂
Could this sauce be frozen if there are leftovers?
Yes! It absolutely can.
I made this once and it did come out bitter, so I tried again with some of your suggestions in the blog post/comments and it was amazing! I ended up making the following changes:
-16 oz of tofu (only size at my grocery store)
-Less roasted red peppers – used the contents of a 12 oz jar. Maybe 1 to 1.5 cups
-Increased to 3 tbsp nutritional yeast
-Added 1/4 cup cashews, soaked for a few mins before blending
-Increased salt slightly to 1.5 tsp
-Added 1 tsp sugar
Thanks for this!
Hi Liz,
Thanks for letting me know! The big challenge with this recipe is that roasted red peppers can taste SO different. I’m going to buy a different brand of roasted red peppers and see how it goes, and add some more notes to the recipe itself! Which brand of red peppers did you buy?
Hey Desiree, I can’t reply to my own comment for some reason, but the pumfu brand I used to make this recipe soy free was Foodies Vegan! Here’s the link if you or anyone else is interested.

Oh thank you!!
I made the Tofu Roasted Red Pepper Pasta last night. Easy, simple and delicious. A real keeper. Thank you for your recipes.
I am on a low fat vegan diet. This ticked all of the boxies.
Hi Anne Marie,
Thanks so much for taking the time to leave a rating and review…I’m so glad you like it!
So good! With the leftover sauce I think I’ll put it on mixed veggies over baked potatoes. And then freeze the rest of the sauce (to see how it does afterwards).
That’s a great idea Sandra…I think it would be delicious over baked potatoes!
As a follow-up up, this sauce was just as good out of the freezer! Afterwards, I used it as a sandwich spread (so great). Also topped a Gardein chick’n Filet with it (put it on and let it cook for 5 minutes more). Excellent.
Oh that’s such a good idea to do a hot sandwich with it, Sandra!!!
