Roasted Red Pepper and Basil Mayo

Roasted Red Pepper and Basil Mayo

I love sauces. To me, nothing ruins a dish/sandwich/meal quicker than there not being enough sauce. It’s a make or break thing for me.

(Well, not having enough salt is also right up there.)

Anyway. Mayo on a sandwich or burger definitely elevates the whole experience for me.

And when you add basil and roasted peppers to mayo?

That really elevates the experience.

I found this recipe in a sidebar in my ATK Quick Family Cookbook* and I’ve made it a bunch of times in the last month or two. So delicious!

(*out of print, look for used copies on Amazon, or try your library.)

Roast your own peppers. Or don’t.

The recipe calls for roasted red peppers, and at first I used the ones in a jar.

But I did not realize that jarred red peppers go bad in a hurry, and when I discovered this, I was in the middle of making a batch of mayo.

I had some orange peppers in the fridge, so I decided to roast my own.

Which, as it turns out, is quite easy. You can roast a bunch, peel them, and freeze whatever you don’t need that day.

From here on out, that is probably what I will do, given that I can often find red peppers for $0.99/apiece, and that is definitely less than what I paid per pepper for the jarred kind.


Roast your own.

Or don’t.

Either will be fine!

And orange peppers work just as well as red peppers; they just make the mayo not quite as brightly colored.

You really should use fresh basil.

I know it’s the end of summer here in the northern hemisphere, and your basil plants are going to die soon.

But dried basil is not going to make this nearly as tasty, so hurry and make it while your basil is fresh, or buy some fresh basil from the grocery store if you make this during the winter.

Food processor or blender?

I use my food processor because I think mayo is way easier to scrape out there as compared to a blender. But either will work fine.

What should you use this on?

Well, anything that mayo, peppers, and basil are good with! It’s great on a variety of sandwiches, and I’ve also used it on sauteed veggies.

Go make a batch!

For all y'all mayo lovers there, if you have not tried the Japanese mayonnaise kind -- you definitely should! My all time favorite is Kewpie brand (no affiliation/interest, just a consumer for over 20 years). Korean copycats are good too, but not that good.

This looks delicious. I do have basil to use up too.

Love the aroma when roasting peppers. I like to blend them with heavy cream to make a quick sauce to drizzle over fried polenta/mush. Basil would be a good addition to the sauce.

Heavens! That sounds good!

When something includes the words, "blend with heavy cream", I am immediately interested!

My eyes just about bugged out of my head when I saw you mention that you can regularly get red peppers for 99 cents a pound!

I feel less bad about my grocery spending in comparison now, considering that 3.99 CAD a pound here is a stock up price! 4.99 CAD is normal.

Red peppers are 0.88 each in Illinois on sale, but “practically free” when I grow in my garden! Also free exercise and Vitamin D and happiness! I freeze unroasted peppers! Then roast from frozen when I have a painful. Or make stuffed peppers! I grow “practically free” basil, too! But since that can’t be frozen, I make pesto and stir that into mayonnaise for something similar to yours- that way it has a little extra protein and flavor. I couldn’t justify paying for grocery store fresh basil & it doesn’t grow well at all indoors. If you aren’t a gardener, but know one, most of us have lots of basil to give away from June- October (northern hemisphere, since it seems that Frugal Girl fans live all over! I’m really liking that!

Just wanted to add: grocery prices ARE higher in Canada than here in the U.S., from what I gather. So I completely agree that you should not feel bad about your spending. If I lived in Canada, I'd spend more too.

Worry less about the amount you are spending and more about how you are shopping. If you are doing things like planning ahead, watching sales, buying ingredients vs. meals, and so on, then you are probably spending exactly what you should be.

You misread. She said .99 each not .99 a pound, so you're pricing is on par.
