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, vegan, 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.

It’s quite a simple preparation, which goes as follows:

Put stuff in a blender, and blend.


See why I love it so much? And just wait until you taste it (seriously).

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.

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.
