Roasted Red Pepper Sauce
This fantastically easy Roasted Red Pepper Sauce takes 5 minutes to make, and adds instant flavor to a ton of foods. I drizzle it on Crispy Smashed Potatoes, spoon it onto Spice Rubbed Chicken, toss it with pasta and vegetables, and more. It’s made without cream, and is friendly to all styles of eating (Whole30 compliant, paleo, gluten-free, etc).

Much like the Basil Vinaigrette I shared last week, this is a sauce that can go on sooooooooo many things. It’s basically flavor sauce.
Drizzle it on chicken, fish, vegetables, and so on, and boom! Flavor.
This is another recipe that I came to love during my Whole30, and I really have to thank the Whole30 for forcing me to rediscover the awesomeness of blender sauces. Because of the restrictions of the program, you’re forced to get creative with simple and flavorful recipes, and having this sauce on hand was key to many satisfying dinners.
Tips for Best Results
Brand matters – Because we will be using purchased roasted red peppers in a jar for this recipe, quality really matters! I have done side-by-side taste tests comparing various brands and it’s INCREDIBLE what a difference there is in flavor. My favorite brand is Divina (I have no affiliation with them).
Use the freshest ingredients possible – The other ingredients here, like the fresh basil, fresh garlic, lemon and so on, should be of peak freshness. Flavor deteriorates as these ingredients age, so try to use the freshest stuff possible.

As far as the preparation goes, it’s quite simple, and goes as follows:
Put stuff in a blender, and blend.
Done.
See why I love it so much? And just wait until you taste it (seriously).
Step by Step Guide:
For the prep, you’ll need roasted red peppers, shallot, garlic, capers, and basil:

Quick note on the peppers: make sure to use a good quality jarred roasted red pepper. I’ve seen brands where it’s a bunch of pepper scraps crammed into a jar, and in my taste tests, it wasn’t as good.
I usually use Divina brand, which I get from Whole Foods. The peppers are huge (about 3 to a jar), have those charred fire roasted bits, and are really delicious.
You may also roast your own peppers, but I’ve done it before numerous times via numerous methods (stovetop, grilling, broiling in the oven), and it’s a lot of work. The flavor isn’t better than a good quality jarred option, in my opinion.
Moving on: throw those ingredients into a blender, and also add some lemon zest, lemon juice, olive oil, salt, and pepper:

Blend on high for about 30-60 seconds, until completely smooth:

The sauce can now be stored in the refrigerator for one week, ready to be drizzled on whatever you’d like.
I LOVE this sauce on those Crispy Smashed Potatoes I posted the other day:

I also dunk roasted broccoli florets into this sauce, serve it with Crispy Spice Rubbed Chicken Thighs, or even plain Slow Cooker Chicken Breast when I’m in a pinch.
More Ways to Serve It
Drizzle on fish like Grilled Salmon, toss with pasta, serve with roasted Spatchcock Chicken or lamb, drizzle a little bit on a fancy vegetable pizza, spread on a sandwich, or dollop a spoonful onto your Turkey Burger.
You can also mix it into Homemade Mayonnaise or Aioli for serving with potatoes. It’s extremely versatile.
FAQ and Tips
Yes, for up to 2 months in an airtight container. You may also choose to freeze the sauce in an ice cube tray, then you can quickly add a few cubes for sauces and such.
Store in the fridge in an airtight container for up to 1 week.
Yes, parsley or oregano would both be great in place of the basil.

I love this sauce. Thank you!!’
I love roasted red pepper sauce! This creamy version is perfect!
I love this sauce. Thank you!!
Instead of peppers from a jar, can one use fresh raw peppers? Also, can one make the sauce with green peppers?
Made this tonight for the first time. Both my husband and I have chronic kidney disease, thankfully, we are in the low risk group – but not wanting to get worse. We both love pasta but now need to truly limit sodium and tomatoes. Red peppers are a kidney friendly veggie, and your recipe was SUPER delicious! It is perfect!
It came together in a snap, which is another bonus. We are going to be enjoying this recipe over and over and over again! I’m definitely sharing it with my cooks club on Facebook and my friends. Thank you so much!!!
Excellent the first time I made it. The second time I added a 1/2 cup + of almonds to add a pesto/crunch thing. Great stuff.
I add a little bit of honey and it just takes the whole thing up a notch. So delicious! Quinoa, black beans, pico, avocado with this sauce on top. My favorite lunch.
pardon me, but could i use something else, like olives in place of capers? this sounds delicious, thank you!
You can leave them out, or you can try the substitution since that might be really good!
This is a delicious tasting sauce and so versatile. I first tried it a few months back because I can no longer tolerate tomatoes. I’ve made it several times to put on Pasta dishes, and veggies. I love it so much I even got a little creative one evening and added some cream cheese to make a variation. It was fantastic too. Thanks for such a wonderfully delicious and versatile recipe!
Hi Joanne! I literally just put this together and had to come to the computer to send you my highest praises!! Looked through so many recipes online and thought your recipe had such a complementing array of ingredients. I and my husband both said WOW! that is fantastic!! Printed the recipe and it will definitely go in my most precious recipes folder. Thank you so much for sharing this. Btw the only thing I did different was put the cut lemon on the grill to char before using. My hubs is making a list of all the things he wants it on!! LOL Beautiful!
Really glad to hear this, Patty! Enjoy!
