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.

Could I use just normal red bell peppers bought from produce if I just grill them? If so how much do you think I’ll need?
Nicole per my experience, 4-6 large roasted red peppers equal approx two cups which is 16 oz’s. as needed for this recipe. I hope this helps.
